Privacy policy
Last updated: October 3, 2026
This policy covers the HomeKnows mobile app (on Google Play and the App Store) and this website, both provided by HomeKnows ("we", "us"). It explains what we collect, why, who processes it for us, how long we keep it, and the choices you have.
What we collect
- Account: your email address, a user id, and your password (stored only as a secure hash by Amazon Cognito).
- Home details: the address, home type, year built and other facts you enter.
- Photos: pictures you take in the app of equipment, labels or problems.
- Documents: photos you add of receipts, warranties and manuals.
- Records the app creates and your input: equipment details, maintenance tasks, history and notes, questions you ask, problem descriptions, and the AI answers you receive.
- Usage counts: how many scans, questions and diagnoses you used this month, to apply plan limits.
- Subscription status: your plan, renewal date and Stripe customer id. Card details are entered on Stripe's page and never reach our servers.
- Push token: an identifier for your device's notifications, only if you allow notifications, so we can send reminders.
- Reports: if you report an AI answer, the report and the answer it refers to.
The app does not access your location, contacts, microphone, or your photo library. It uses the camera only when you take a picture, and the system file picker only for files you choose.
How we use it
Only to provide HomeKnows: to identify your equipment, build maintenance plans, answer your questions, assess problems, send reminders, review reports about AI answers, keep the service secure, and manage your subscription. We do not sell your data, use it for advertising, or track you across other apps or websites. There are no ads and no third-party analytics in the app.
AI processing
Photos, documents, questions and problem descriptions are sent to AI models hosted on Amazon Bedrock (Amazon Web Services) to produce results. Amazon Bedrock does not use this content to train models and does not share it with model providers. AI answers can be wrong or incomplete: HomeKnows gives general information, not professional advice.
Who processes data for us
We use these service providers, which process data only on our instructions to run HomeKnows:
- Amazon Web Services (United States): hosting, database, file storage, sign-in (Cognito), sign-in emails, and AI (Bedrock).
- Expo (650 Industries): delivers push notifications using your push token and the reminder text.
- Stripe: subscription payments and billing records, if you upgrade.
We may disclose information if required by law. We do not share your data with anyone else.
Where it's stored and how it's protected
Your data is stored on Amazon Web Services in the United States. It is encrypted in transit (HTTPS/TLS) and at rest. Files are private to your account and can only be accessed with your sign-in.
How long we keep it
- Account data, homes, items, photos and documents: until you delete them (see below) or delete your account.
- Encrypted database backups: expire automatically within 35 days.
- Server logs: deleted after 30 days.
- Payment and invoice records: kept by Stripe and us as required by tax and accounting law (typically up to 7 years).
Your choices and rights
In the app you can view your home, items, documents, warranties and history. You can delete any item (open the item, then Delete item), which also deletes its maintenance tasks, photos, documents and warranty. You can delete a single document on its own in Documents (Delete document); if that document added a warranty, the warranty is deleted with it. Your home, its timeline history, your questions and answers, and any photo attached to a problem report or diagnosis are deleted when you delete your account. You can turn off notifications in your phone's settings. You can delete your account and all its data at any time in the app (Settings → Delete account) or on our account deletion page, without the app. Deletion from our live systems happens immediately. To request a copy of your data, or to ask us to correct or delete specific data, contact us as described on our Support page.
Children
HomeKnows is intended for adults (18+) and is not directed to children. We do not knowingly collect data from children under 13; if you believe a child has given us data, contact us (see our Support page) and we'll delete it.
Changes
If we change this policy, we'll update the date above and, for significant changes, tell you in the app or by email.
