Privacy
What HouseMouse collects, why, who helps run it, and how to see, correct or delete it.
Last updated October 13, 2026
The short version
- HouseMouse never asks for your email inbox, bank logins or passwords, and never keeps your street address.
- The AI behind HouseMouse runs on private models: the provider doesn’t keep or log what you send, and none of it trains an AI.
- Your partner sees what’s in your shared household. That’s the point of it.
- We don’t sell your information or use it for advertising.
- You can see and correct the household’s record on the web page, and delete your account there at any time.
Who we are
HouseMouse is an independent project, not yet a registered company. Its privacy officer is responsible for your information. For anything on this page, including access, correction and deletion requests, write to privacy@housemouse.house. We answer within 30 days.
What we collect
- Your phone number, to sign you in with a code and, if you connect it, to reach you on WhatsApp.
- Your number on the waitlist, if you join it while HouseMouse is invite-only. We keep it only to invite you, and delete it if you ask.
- A first name, if you choose one, so HouseMouse and the money pages can tell the two of you apart.
- What you tell HouseMouse: your chats on WhatsApp and on the web page, and the documents, photos and voice notes you send it.
- Your household’s record: bills, costs and who paid, the Home Plan, appliances and warranties, routines and chores, groceries and dinner.
- Where your home is, roughly: your province or state, and if you give them, your postal code and city. Never your street address. Only the first three characters of the postal code reach the AI.
- Your setup answers, kept in your own browser for up to 30 days until you save your plan.
- How the site is used, described under Analytics and cookies below.
How we use it
To run HouseMouse for your household: answering you, keeping the record, sending the reminders you’ve asked for and proposing changes for one of you to approve. We also use it to keep the service secure and, in aggregate, to understand which parts work. We don’t use it for anything else without asking you.
Who else handles it
These services process information on our behalf, only to run HouseMouse. Your information is stored in, and may be processed in, the United States, where it is subject to that country’s laws.
| Service | What it does | What it receives |
|---|---|---|
| Supabase | Database, sign-in and file storage, in the United States (US East) | Everything described above |
| Railway | Runs the website and HouseMouse | Requests as they pass through; it stores nothing of yours |
| Venice AI | The AI behind HouseMouse, on private models that don’t keep or log what is sent | Your messages and recent chat, the household’s record, first names, documents and photos you send, voice notes to transcribe, and the first three characters of your postal code |
| WhatsApp (Meta) | Carries messages between you and HouseMouse, if you connect WhatsApp | Your WhatsApp number and the messages, documents and photos sent either way |
| MessageBird | Sends the code you sign in with | Your phone number |
| Cloudflare | Checks the sign-in form isn’t being used by a bot | Technical details from your browser while you use that form |
| PostHog | Product analytics, in the United States | Which pages and buttons are used, with a random ID; session recordings with every piece of text and input masked; for each request to HouseMouse’s AI, its size, cost and timing and a general error type, never its words |
Inside your household
A household is at most two people, and both of you see the same record: shared costs, what HouseMouse remembers, and its chat. In a shared WhatsApp chat HouseMouse never says which of you did what, except who owes whom on shared costs.
Analytics and cookies
- Sign-in cookies keep you signed in to the web page.
- PostHog measures which pages and buttons are used. It is linked to a random ID, never your name or number, and any event that looks like it holds a phone number is dropped before it is sent. Session recordings mask every piece of text and every input.
- There are no advertising or cross-site tracking cookies.
If your browser sends Global Privacy Control or Do Not Track, PostHog doesn’t load at all: nothing is measured and nothing is recorded. The site works the same either way, and if your browser blocks analytics.
How long we keep it
Your household’s record is kept while your account is open. Some things go sooner, automatically: daily briefs after 14 days, sent reminders after 90 days, and the household summaries HouseMouse works from after 90 days. Anything you tell HouseMouse to forget stops being used at once. A fact or staple it forgot can be brought back from the web page for 30 days, and is then deleted for good.
Deleting your account
Delete your account from the web page (You two, then Delete account), after confirming it’s you with a code.
- If you’re the only member, the household, its record, and the documents and photos stored for it are deleted with your account.
- If your partner is still a member, you leave and the household stays theirs. What you added stays in the record, shown as from a former member, and your phone number is removed.
If you leave and your partner stays, the documents and photos you sent stay with the household too. To have those erased, or to ask for anything else to be deleted, write to privacy@housemouse.house.
Your rights
Wherever you live, you can ask what we hold about you, have it corrected, have it deleted, or withdraw your consent (which may mean closing your account). Write to privacy@housemouse.house.
In Canada
We handle personal information under the Personal Information Protection and Electronic Documents Act (PIPEDA). If you’re not satisfied with our answer, you can complain to the Office of the Privacy Commissioner of Canada.
In the United States
You have the same rights to know, correct and delete, and we won’t treat you differently for using them. We don’t sell or share personal information for advertising.
Keeping it safe
Information is encrypted in transit and at rest. The database lets each household see only its own record, and files sit in private storage. Sign-in uses a one-time code, so there’s no password to steal.
Who it’s for
HouseMouse is for adults. We don’t knowingly collect information from anyone under 18.
Changes
When this notice changes, the date at the top changes too. If a change affects how your information is used, we’ll tell you before it takes effect.
