Your Data and Privacy

Kaizora holds some of the most personal data there is. This page says plainly who can see it and where it goes. The Privacy Policy has the full detail.

Who Can See Your Data

• You. One account is one person. Every row of your data belongs to your account alone, and the database itself refuses anyone else’s reads and writes, whatever the app asks for.
• No one else using Kaizora. Nothing is shared between accounts.
• The people who run Kaizora, only when needed. Your data is encrypted on its way to and from the app and where it’s stored, but it isn’t end-to-end encrypted: the people who operate Kaizora could reach it. It’s looked at only to run the service, to fix a problem you’ve asked about, or when the law requires it.

Kaizora has no ads, no trackers, and no analytics in the app, and your data is never sold. To protect your account further, turn on two-factor authentication.

What Stays on Your Device

• Files you import are read in your browser; only the entries read from them are saved, never the file. See Import a File.
• Photos: only each photo’s time, position, and camera are read and saved; the photos never leave your device.
• Your profile photo: only a small square cut from it is uploaded, never the original or its time and place.
• Your days’ stays and trips are worked out on your device, and never looked up by address.

What’s Sent to Other Services

• Searching for a place sends what you type, and your device’s rough position to rank nearby results, to Photon, a search service built on OpenStreetMap.
• Maps load their tiles from OpenStreetMap, which sees which area you’re viewing.
• Withings, once you connect it, sends your readings to Kaizora. The access it gives is kept where the app can’t read it, and disconnecting stops it.
• The AI overview, only once you agree, sends Anthropic a summary of your numbers, never your name, notes, or locations, and never reproductive health data. See Get an AI Overview of Your Data.

Outdoor air from public stations is downloaded for everyone at once, so your position isn’t sent to look it up.

Your Location

Kaizora records your location only when you log one, import a history, or turn on tracking on a device. Tracking is off until you turn it on, and records only while Kaizora is open.

Notifications on Your Screen

Notifications shown outside the app say only what kind of thing happened, such as “A metric is out of range”, never which metric or value.

Export or Delete

• Export Your Data, free, at any time.
• Delete What a Source Brought In, or delete an entry.
• Delete Your Account, with everything in it.

A Note on Health

Kaizora helps you keep track of your own data. It doesn’t diagnose or treat anything, and its ranges and flags aren’t medical advice.
