Legal
Privacy Policy
What this site collects, what it deliberately does not, and which other companies your browser ends up talking to. Written against the actual code, so it is specific rather than reassuring.
Effective Terms of Use
The short version
You can search this entire site without telling us anything. There is no sign-up wall and nothing to fill in before you can look at a house. Signing in exists, and it gates exactly one feature: the watchlist. Everything else — every search, every filter, every home — works without it.
There is exactly one thing we ask you for, and only if you ask us first. Looking asks for nothing. Saving a home to a watchlist means signing in with Google, because a watchlist has to live somewhere that is yours and alerts need somewhere confirmed to go. We then store your verified email address, the words you agreed to, when you agreed to them, and the list of things you are watching. No profile, password or budget.
We only write to an address someone has proved is theirs. Typing an address into a form does not prove anything, so those addresses are held and never written to. Signing in with Google is the proof, and it is the only way an alert email gets sent — which is the entire reason signing in exists here. We do not ask Google for your name or profile picture.
What we also receive, from everyone, is the ordinary record of a web request — your IP address, your browser type, which page you asked for — plus usage analytics, part of it cookieless and part of it not. Some of that analytics we keep ourselves: a record of which pages were used, holding no cookie and no IP address, deleted after 90 days. And when a page shows a map or a photograph, your browser fetches those directly from other companies, which see your IP address as a result. All of that is set out in full below.
We do not sell anything about you and we run no advertising. We do run Google Analytics to understand site usage, which sets a cookie that recognizes your browser on a repeat visit to this site — the “Cookies and device storage” and “Who else your browser talks to” sections below say exactly what it does and does not do.
The one thing we ask you for
What we ask, and when
Looking asks for nothing. Saving a home or community to a watchlist asks you to sign in with Google, once: pressing Save while signed out takes you to the sign-in page, and the save completes when you come back. We ask Google to verify the email address before we ever send anything to it.
The email permission and the notice that continuing accepts the Terms of Use are printed against the Google button, on the screen where you press it.
What we store
- Your verified email address, Google’s stable account identifier, what you saved and which kinds of change you asked to hear about.
- The exact consent and Terms sentences shown to you, copied word for word with the date and source page, plus a one-way hash of the random session token that lets this browser find the server list again.
That is the complete list. No name, profile, password, mobile number, postal address or information about you from another source.
Two things we want to be straight about
Older unverified subscriptions are never emailed. An earlier version of this site allowed someone to type an address. Those legacy records remain separate and silent until the owner verifies the address; the current product no longer creates them.
Deleting is a button, not a request. Your account page and your watchlist each carry a control that erases your address, your consent record, your Terms acceptance, every watch and every saved search immediately. You do not have to email anyone or explain why.
Signing in with Google
Signing in gates one feature: the watchlist. Every page, every search, every filter and every home on this site works without it; saving something to watch is what requires it, because a watchlist has to belong to someone before changes can be recorded and delivered for them. We refuse to write to an address nobody has proved is theirs, proving it ourselves would mean emailing you a link — which is the very thing we are trying to earn the right to do — and Google has already done that check and will tell us the answer.
What Google tells us
- A stable account identifier. Not your email address: Google lets an account change its address, and this is the thing that does not move. It is how we know you are the same person next time.
- Your email address, and Google’s statement that it has been verified. We refuse the sign-in outright if that statement says otherwise.
What we ask Google for, and what we do not
We request two permissions — openid and email — which is the smallest set that produces the facts above. We do not request access to Gmail, your contacts, your calendar, your files, or anything else, and Google’s consent screen will confirm that.
We also deliberately do not ask for offline access. That is the permission that hands a site a long-lived key to talk to Google about you later, without you present. There is no moment after sign-in when this site needs to contact Google again, so we never hold one.
What happens to the list you already had
If you were already watching homes in that browser — including a list saved on the device under an earlier version of this site — those watches and saved searches move onto your account and the old record is deleted. It is your list either way — this only stops it disappearing at the moment you sign in. Nothing merges based on an address alone: only the subscription belonging to the browser you are signing in from, and never one that belongs to another signed-in account.
Signing out is not deletion, and we do not pretend otherwise. Signing out ends that browser’s session. Deleting your details erases the address, the consent record, every watch and every saved search — and that is a separate button that says so.
What we receive when you visit
Server logs
Our host, Vercel, records the ordinary information any web server receives in order to serve a page and to stay online: your IP address, your browser and operating system, the page you requested, the page you came from, and the time. This is standard infrastructure logging, used to run the site, diagnose faults and defend against abuse. Vercel retains these logs for a limited period under its own retention policy; we do not build a separate copy of them and we do not use them to profile visitors.
Suggesting a market
Vercel resolves your IP address to a coarse location at its edge and passes us the city, region and country — not the address itself. We use that for exactly one thing: if it falls inside a market we cover and you are looking at a different one, we show a banner offering to switch. It is an offer and nothing more. The page you asked for is the page you get, and no market changes unless you press the button.
- We do not store it. The city and region are read while your page is being built and are gone when the response is sent. Nothing about your location is written to our database, and it is not part of the visit record described below.
- We still do not ask your browser. This uses only what your request already carried in reaching us. The site never calls the browser’s location API, so you will never see a location permission prompt from us.
- Your answer stays on your device. If you dismiss the banner, or accept it, that is recorded in your browser’s local storage so we do not ask again. It sets no cookie and is never sent to us.
- It is often wrong, and it fails quietly. An IP address places a network, not a person — a VPN, a corporate connection or a phone can resolve anywhere. When the location does not land inside a market we cover, we show nothing rather than guess at the nearest one.
Vercel Web Analytics
We use Vercel Web Analytics to understand which pages are used. It is worth stating precisely what it does, because “analytics” covers a lot of very different things:
- It sets no cookies and stores nothing on your device.
- It does not follow you to other websites. There is no cross-site identifier.
- It identifies a visit by a hash computed from your request — derived in part from your IP address — rather than by storing your IP address or a persistent ID. Vercel discards that hash after 24 hours.
- It records the page URL, the referring page, coarse location (country or region level), device type, operating system and browser, and the time.
We call this pseudonymous rather than anonymous, because that is what it is: for a day, a hash groups one visitor’s page views together. Note also that this site puts your search criteria in the page URL — the cities, price range, bedroom count and any text you typed — so those travel into the analytics record along with the URL. We do not use any of it to identify anyone, and we could not.
Our own record of what pages were used
We also keep a copy of this ourselves, in our own database, rather than only sending it to the two companies above. It is the same information — which page, which link, when — and it exists because an operations page we can actually read is the only way to tell whether the site is working for the people using it, and neither of the tools above can be read from inside this site.
Being our own copy, we can be exact about it:
- It sets no cookie and stores nothing on your device. Nothing changed about the cookies on this site when we added it — the list in “Cookies and device storage” below is the same list.
- It identifies a visit by a hash computed from your request — from a secret of ours, the date, your IP address, your browser’s user-agent string and this site’s address. Your IP address is not stored. It goes into that calculation and is discarded in the same breath; there is no column for it in our database and nothing there it could be recovered from.
- The hash changes every day at midnight UTC, because the secret it is built from rotates. The practical consequence is the one worth stating: we can see that a visit read four pages this afternoon, and we cannot tell that the same browser was also here last Tuesday. We gave that up deliberately.
- It does not follow you to other websites. There is no cross-site identifier, and there could not be one — the hash is specific to this site’s address.
- It records the page URL, the referring site’s host name (never the full referring URL), a device class, a browser family, an operating system family, and the country and region our host tells us. No version numbers, and no full user-agent string.
- If your browser is carrying a signed-in session, the visit is marked as a subscriber’s and not as yours. Which subscriber is not recorded, and there is nowhere in that table to put it. We do not link your browsing to your account.
- It is deleted after 90 days, by a job that runs every night. Unlike the retention question for the two tools above, this one is entirely ours to answer.
Same caveat as for Vercel’s tool, for the same reason: this site puts your search criteria in the page URL, so the cities, price range and bedroom count you chose travel into this record along with the URL. What you typed into a search box does not — the record of a search says that one happened and on which page, never the words.
Google Analytics
We also run Google Analytics on every page. It works differently enough from Vercel’s tool that describing it in the same terms would be misleading:
- It sets cookies — two of them, covered in full under “Cookies and device storage” — the first time you load any page, whether or not you ever subscribe or sign in.
- It identifies your browser by a persistent identifier stored in those cookies, not a hash discarded the next day. By Google’s own default, which is what we use, that identifier lasts up to two years unless you clear it yourself.
- It records what Vercel’s analytics records — page URL (including your search criteria, as above), referring page, coarse location, device and browser — plus your IP address, sent to Google directly by your browser rather than by us.
- What Google itself retains, and for how long, is set in our Google Analytics account and governed by Google’s own privacy policy once the data reaches them — not by this document, and not within our control the way Vercel’s 24-hour discard is.
We are naming that trade-off rather than letting the word “analytics” above cover both tools as if they behaved the same way. They do not.
Who else your browser talks to
Some things on this site are served by other companies rather than by us. Your browser contacts them directly, which means they see your IP address even though we never send them anything about you. This is the part of a privacy policy most often left out, so here it is in full.
| Who | When | What they receive |
|---|---|---|
| CARTO | Whenever a map is displayed | Your IP address, your browser type, the page you were on, and which map tiles you requested — which indicates the area you were looking at |
| Builder websites and image hosts | Whenever a home photograph is displayed | Your IP address, your browser type, and the page you were on. Photographs are loaded from the builder’s own servers rather than copied onto ours. Where a home is shown as a drawing instead, that drawing is ours and is served from this site |
| Google Analytics | Every page view | Your IP address, your browser and device, the page URL — including your search criteria, as noted above — the referring page, coarse location, and a persistent identifier that recognizes this browser on a later visit. See “What we receive when you visit” for the full description |
| Google (sign-in) | Only if you press “Continue with Google” | During sign-in, everything Google normally sees when you sign in to something: your IP address, your browser, and that it was this site asking. No Dwellmark page sends Google anything further about your account after that sign-in finishes — though Google Analytics, listed above, still runs on every page regardless |
| Vercel | Every page view | Hosting and analytics, as described above |
| Supabase | Server-side only | Our database. Almost all of it is property information; it also holds subscriber addresses and consent records, which no browser ever connects to it directly to reach |
| Resend | Server-side only, when an alert is sent | Our email provider. To send you a message they necessarily receive your address and the message itself. Your browser never contacts them, and our messages carry no tracking pixel — we do not ask them, or anyone, whether you opened one |
Vercel, Supabase and Resend handle data on our behalf, under contracts that let them use it to provide the service to us and for nothing of their own. CARTO and the image hosts are not doing anything for us — they are simply the servers your browser has to reach to draw a map or show a photo. Google is different from all of them: sign-in is on our behalf, the way Vercel and Resend are, but Google Analytics is not — Google’s standard terms let it use what Analytics collects for Google’s own purposes too, under Google’s own privacy policy, which we do not control. And Google now reaches every visitor, not only people who sign in.
One thing we do not do, which most sites do: our fonts are served from this site rather than from Google Fonts, so font loading itself does not reveal your IP address to Google. That remains true on every Dwellmark page. It no longer means Google is kept out of the picture, though — Google Analytics, above, contacts Google on every page view regardless of fonts.
What we do not do
These are true today, and we will change this page on the day any of them stops being:
- We do not sell your personal information, and we do not rent, trade or otherwise hand it to anyone for money or for anything else of value.
- We do not share it for advertising. There is no advertising on this site, no ad network, no advertising pixel, no conversion tracking and no behavioural-targeting arrangement with anyone.
- We do not run retargeting, and we do not buy or receive data about you from data brokers. We do run Google Analytics, which is a tracking technology in the ordinary sense of that word — it sets a cookie and recognizes your browser again on a later visit to this site. “Cookies and device storage” above and the Do Not Track disclosure below say exactly what it does. We also keep our own record of which pages were used, described above; it sets no cookie, stores no IP address, and cannot recognize your browser tomorrow.
- We do not write to unconfirmed addresses. We hold addresses people typed in and gave us permission to use, and we send nothing to any of them, because typing an address does not prove it is yours. The only messages that leave this site go to addresses confirmed by signing in.
- We do not track whether you opened an email. No tracking pixel, no rewritten links, no open or click reporting. We do not know, and have not asked our email provider to tell us.
- We have never sent a marketing email, and there is no mechanism to. The only two messages this site can produce are a change to something you asked to watch, and a one-off confirmation the first time you sign in.
- We do not ask for your location. The site never requests location access from your browser, so no location permission prompt ever comes from us. We do use the coarse city and region our host resolves from your IP address — which your request carried anyway — to offer to switch you to a nearer market, and that offer changes nothing until you accept it. It is set out in full under “Suggesting a market” above, including the fact that we store none of it.
- We do not ask for anything we do not need. No name, no password, no budget, no “tell us about your search” form standing between you and a listing.
The one qualification we will make on “we do not sell or share”: because maps, photographs and Google Analytics are all served by other companies named above, loading a page necessarily reveals your IP address to them. For maps and photographs we receive nothing back except the tile or the photograph. Google Analytics is different — we receive the usage data described earlier in exchange, which is the entire reason we run it. We would rather flag that than make a flat claim that a careful reader could pick apart. Our own record of page use is the one piece of this that goes nowhere: it is written to our database and read by us, and no other company is involved in it.
Alerts, and what we will never send
Email alerts are running. Text messages are not. If you have signed in with Google, changes to the homes, communities and searches you watch are emailed to you. If you only typed an address into a form, it is being held and nothing is being sent to it — see above for why. No text message has ever been sent by this site to anyone.
These are the terms, and they are the ones written into the sentence you agreed to rather than a separate set of aspirations:
- We confirm your address before the first message. Nothing goes to an address that has not been confirmed — which also means nothing goes out on the strength of a permission recorded before the confirmation existed.
- At most one message a day for each kind of update — the homes you watch get an alert, the communities you follow get a brief — and only when something you are watching has actually changed. On a day when nothing changed, nothing arrives. Several changes on the same day become one message, not several. If you would rather read everything once a week, your account page can switch delivery to Saturday mornings — still at most one message per kind, covering the week.
- Only what you asked for. No newsletters, no “you might also like”, no re-engagement campaigns, no marketing of any kind. There is exactly one message that is not a change you subscribed to: a single confirmation the first time you sign in, saying what will and will not arrive. If we ever want to send anything else, we will ask separately.
- Every message has a working unsubscribe link, and honours the one-click unsubscribe button your mail app shows — and texts will honour STOP, with HELP returning who we are and how to reach us. All of them take effect immediately and permanently. Stopping the emails does not delete anything: your watchlist stays yours and you can switch them back on. You do not need a message to stop either, and if you want everything erased rather than paused, the button on your account page and on your watchlist does that instead.
- No open tracking and no click tracking. Our messages contain no tracking pixel and no rewritten links. We do not know whether you opened one.
- We will never sell, rent or share a subscriber list with builders, agents, lenders or anyone else. Not now, and not as part of any future arrangement.
- Text messages need their own consent, given separately, with the sender, the frequency, the rates, STOP and HELP shown next to the box rather than behind a link. Giving us an email address is not permission to text you, and there is no way to give us both at once.
An earlier version of this page warned that switching delivery on would force unsubscribing to leave behind a minimal suppression record — enough to know not to contact you again — and that this would be the one part of “delete erases everything” that had to change. It did not. Unsubscribing keeps your account and flips a switch on it, so there is nothing to suppress; and deleting erases the row entirely, after which nothing about you exists to be written to. We never import or re-import an address from anywhere, so there is no list you could reappear on. We are leaving the retracted warning here rather than deleting it, because a policy that quietly drops a promise it made is one nobody can rely on.
Information about homes, not about you
Most of what this site stores is information about houses: prices, floor areas, lot numbers, community names, builder offers and how those changed over time. It comes from builders’ public websites, and it describes new-construction inventory that a builder is currently advertising for sale — not a home someone lives in, and not anything about a buyer or an owner.
We do not collect or publish information about residents, owners, past sales, or the people involved in any transaction. If you believe something on this site identifies you personally, write to support@serenialabs.space and we will look into it and remove it if it does.
How long we keep things
A policy that says “as long as necessary” has said nothing. Here is what each thing actually is:
- Your address, your consent record, your Terms acceptance and your watchlist: until you delete them. There is no expiry timer and no automatic clean-up, which we would rather admit than describe a job that does not run. What there is instead is a button on your account page and on your watchlist that removes all of it in one press, at any time, with no waiting on us.
- Messages we sent you: a record that a message went out, which message, and when — kept as long as your account is, and erased with it. Resend holds its own copy of what it delivered, under its retention schedule. We do not record whether you opened anything, because we do not collect that at all.
- Your session: one row per browser, holding a hash of a token and the time it was last seen. Removed when you delete your details or sign that browser out.
- Server logs: held by Vercel under its own retention schedule, which is a limited period measured in days for request logs. We keep no separate copy.
- Our own record of page use: 90 days, then deleted by a job that runs every night — the one retention period on this list that is entirely ours to set. It holds no cookie and no IP address, and the hash that groups one visit’s pages together stops working at midnight, so what is left after that is a set of pages and times that cannot be gathered back into a person.
- Analytics we send elsewhere: Vercel discards its per-visitor hash after 24 hours; what survives is counts — page views by day, by country, by device — which are not about you and cannot be resolved back to you. Google Analytics is different: the cookie identifying your browser lasts up to two years by default, and how long Google itself keeps the resulting data is set in our Google Analytics account and governed by Google’s own privacy policy — not by us.
- Information about homes: kept indefinitely, on purpose. The history is the product, and a price observed in 2026 is worth more in 2028 than it was the day we saw it. None of it is about you.
If we ever start deleting dormant subscriptions on a schedule — which would be a reasonable thing to do — we will say so here, with the period, before it starts.
When information could leave us
We have said we do not sell or share anything about you. That is the general rule, and it has three specific exceptions, all of which we would rather name than leave you to discover:
- The companies that run this thing for us. Vercel hosts the site, Supabase holds the database, and Resend sends the alert emails — which means Resend necessarily receives your address and the message itself. They process what they process in order to provide that service to us, under their terms, and not for purposes of their own. They are named above and there are no others.
- Google, if you choose to sign in. This one is the other way round from the rest of the list: signing in sends you to Google, and Google tells us a stable identifier and your verified address. We send them nothing about your watchlist, what you searched for or whether you came back.
- If the law compels it. We may disclose information where we are required to by law, by a subpoena or by other valid legal process, or where we believe in good faith it is necessary to prevent imminent physical harm. We will insist on process that is actually valid, we will give no more than it asks for, and we will tell you it happened unless we are legally prohibited from doing so — in which case we will tell you as soon as we are allowed to.
- If the business changes hands. If Serenia Labs LLC is sold, merged, or its assets transferred, subscriber information could transfer with the rest of the business. If that happens: any buyer takes it subject to this policy for information collected under it, and we will publish notice here — and email subscribers who have given us an address — before the transfer, with enough time to press the delete button first if you would rather not come along.
That is the complete list. Not to advertisers, not to builders, not to agents, not to lenders, not to data brokers, not for money, and not as a favour.
Your choices, and asking us for things
We will be straight with you about the legal position rather than claim a compliance badge. Our markets are in Arizona, California, Texas, Georgia, North Carolina, South Carolina, Florida, Tennessee and Washington, so those are the states most people reading this are in — though anyone in the country can use the site, and which state you are in changes what we owe you. Some of those states have a comprehensive consumer privacy statute and some have none — and as of the effective date of this policy, this is a small, free operation that falls under the entry thresholds every one of those statutes sets before it applies to anyone. We are not going to claim to “comply with” regimes that do not reach us; an unkept promise of that kind is worse than no promise.
That is not the whole picture, and we will not let it stand as if it were. A separate set of laws — California’s Online Privacy Protection Act among them — applies to any commercial website that collects personal information from a resident, with no size threshold at all. This document is written to meet those: it says what we collect, who else receives it, how to review and change it, when it took effect, how you will learn if it changes, and how we respond to tracking signals. And if we ever cross a threshold into one of the comprehensive statutes, we will comply with it and say so here rather than wait to be asked.
In the meantime we offer the same things voluntarily, to anyone who asks, wherever you live and without needing a legal basis for asking:
- Ask what we have about you. If you have subscribed, the answer is your address, the sentence you agreed to and when, the Terms acceptance recorded at the same moment, and your watchlist. If you have not, it is server logs, a day of pseudonymous Vercel analytics, and whatever Google Analytics has recorded against your browser — which is Google’s record, not a database we query directly. Either way we will say so honestly, and your account page already shows you most of it without having to ask.
- Ask us to delete something. If we can identify it, we will.
- Ask us to correct something.
- Ask for a copy of what we hold about you, in a form you can keep.
- Ask a question and get an actual answer about how any of this works.
Write to support@serenialabs.space — starting the subject line with “Privacy” helps, but is not required. We aim to reply within 30 days, we will never charge you for asking, and we will never treat you differently for having asked. If we cannot identify you from what you send us — which is genuinely possible here, because we hold no name — we will tell you that rather than demand more personal information to prove a point.
Tracking signals
Do Not Track. We do not currently change this site’s behaviour based on a Do Not Track signal. Google Analytics loads and sets its cookies the same way whether or not your browser sends one, and our own record of page use is written the same way too. If we add Do Not Track handling later, we will describe exactly what it does here rather than imply more than it does.
Global Privacy Control. We honour it. We treat it as an instruction not to sell or share your information — which we already do not do, so it changes nothing, and we would rather say that plainly than imply we switched something off for you.
Things you can do without asking us
- Delete everything we hold about you, immediately. The button is on your account page and on your watchlist: it erases your address, consent record, Terms acceptance, every watch and every saved search, and signs your browser out. No email, no form, no waiting for us. A list an earlier version of this site saved on your device can be removed by clearing this site’s browser data.
- Stop the emails without deleting anything. One switch on your account page, the link at the bottom of any message, or the unsubscribe button in your own mail app. Your watchlist is untouched and you can switch them back on.
- Stop watching one thing without removing anything else, from the watch button on any home or community.
- Block scripts or use a tracker blocker. The site is built to work without analytics — Vercel’s or Google’s — and blocking either or both costs you nothing.
Security, and what happens if we get it wrong
Traffic to this site is encrypted in transit. Our database enforces row-level security, and the credential the website itself uses can only read the catalogue of homes — it cannot write to it, and it cannot read subscriber addresses or consent records at all. Those are reachable only from server code holding a separate credential that is never sent to a browser.
There are no passwords here to steal. Subscribing does not create one, because there is no login: your browser holds a random token, and what we store is a one-way hash of it. Someone with a copy of that table cannot turn it back into a working session. That removes the largest single category of breach from this site entirely.
No system is perfectly secure, and we are a small operation. If a breach affects personal information, we will notify the people affected and any regulator that the law requires — and we will get that right by where you are, not by where we are. Breach notification in the United States is set by the law of the state the affected person lives in, so two subscribers in different states are owed different notices on different deadlines, and the state we are incorporated in decides neither. We will work to the shortest deadline that applies to anyone affected rather than the longest, and we will tell you what happened rather than the least we can get away with.
Children
This site is for adults shopping for a house. It is not directed to children, and we do not knowingly collect personal information from anyone under 13. We do not ask anyone’s age, because collecting birthdates in order to prove we do not want them would mean collecting more personal information, not less. If you are a parent or guardian and believe your child has provided us with something, write to support@serenialabs.space and we will delete it.
Where we operate
This service is offered to people in the United States. It covers homes in Phoenix Metro (Arizona), San Francisco Bay Area (California), Austin Metro (Texas), Dallas–Fort Worth Metroplex (Texas), Houston Metro (Texas), Atlanta Metro (Georgia), Charlotte Metro (North Carolina and South Carolina), Orlando Metro (Florida), Tampa Bay (Florida), Nashville Metro (Tennessee) and Seattle Metro (Washington), and it is offered to people in Arizona, California, Texas, Georgia, North Carolina, South Carolina, Florida, Tennessee and Washington and anywhere else in the country someone might be shopping from. Our infrastructure is in the United States, so information is processed there.
It is not offered or directed to people in the European Economic Area, the United Kingdom or Switzerland, and we do not knowingly offer services to, or monitor the behaviour of, people located there.
Changes to this policy
When we change this policy, we will change the effective date at the top. If we make a change that materially reduces the protection this policy describes — for example if we add advertising, begin sharing information with a third party, or start sending messages — we will say so clearly on the site rather than quietly editing this page, and we will do it before the change takes effect, not after. Where we hold an email address for you, we will use it.
Previous versions are available on request.
How to reach us
