Privacy Policy
HomeJot · Effective October 17, 2026
HomeJot helps you keep your home's records: the equipment and finishes in it, their manuals, receipts and warranties, your notes, and maintenance tasks. It is built so that your records stay on your iPhone. There are no accounts, no ads, no analytics and no tracking.
What stays on your iPhone
Everything you save in HomeJot (items, documents, notes, photos, scanned pages and tasks) is stored only in the app on your iPhone. We have no copy of it. The text in your photos and PDFs is read on the iPhone itself.
Like other app data, your records are included in your iPhone's iCloud or computer backups, which Apple's or your computer's own privacy terms cover.
What leaves your iPhone, and only when you use an AI feature
Three optional features use AI. Nothing is sent unless you use one of them:
- Scan a label sends the photo of the label, so its brand, model and serial number can be read.
- Ask sends your question with your home's records as text: items, notes, tasks, document titles and the text read from your documents. It doesn't send the photos or PDF files themselves.
- Suggest maintenance sends the same kind of text records, for one item or the whole home, and today's date.
These go to the HomeJot service, which picks the parts that matter for the request and passes them to our AI provider, OpenAI, to produce the answer. The answer comes back to your iPhone. The HomeJot service doesn't save the photo, question, records or answer.
We ask OpenAI not to store these requests. Under OpenAI's terms for its API, data sent to it is not used to train its models, and it may be kept for up to 30 days to detect abuse before being deleted. See OpenAI's privacy policy.
What the HomeJot service keeps
- A device key. To make sure requests come from the genuine HomeJot app on a real iPhone, the app uses Apple's App Attest, which creates a random key on your iPhone. The service keeps the public part of that key. It doesn't identify you or your iPhone to us.
- A daily count of AI requests per device key, to apply the daily AI limit.
- Usage totals: how many requests each AI feature handled each day and how much AI processing they used, added up across everyone, to track running costs.
- Server logs. Our hosting provider, Fly.io, records each request's IP address, time and web address, and any errors, for a limited time, to keep the service running and secure. The logs don't contain your photos, questions or records.
Sharing
We don't sell or rent data, and we don't share it with advertisers or data brokers. The only companies involved are the ones above that run the service for us: OpenAI (AI processing) and Fly.io (hosting).
Your choices
- You can use HomeJot without the AI features; then nothing about your home leaves your iPhone.
- To delete your records, use Settings › Erase all data on this iPhone in the app, or delete the app. Remember to delete any backups you no longer want.
- Because we have no accounts and keep nothing that identifies you, there is no account to delete. You can still contact us with any question about your data.
Children
HomeJot is meant for adults managing a home. It isn't directed at children under 13, and we don't knowingly collect anything from them.
Changes
If this policy changes, we'll update it here and change the date at the top. If a change affects what leaves your iPhone, we'll also say so in the app.
