Chrysa privacy policy

Last updated 12 September 2026

Chrysa is a personal life companion. Everything it knows about you lives in a database on your phone. There is no account, no login, and no server of ours. We never see your data, so we cannot sell it, share it, or lose it.

What stays on your phone

• Who you said you want to become, your goals, your reflections, and the line you wrote in your own words.
• What you log: activities, meals, sleep, water, routines, the optional weekly weight number.
• On Android, if you allow it: per-app screen time and app opens (usage access), a sleep estimate from when your phone goes quiet, and your step count. These are read on the device and never transmitted.
• On Android, if you allow it: events from the calendars you pick, so free time can route around them. Read on the device and never transmitted; Chrysa never writes to your calendar.
• Your settings, including which apps you chose for "a pause before an app".

The one thing that can use the internet

In You there is a switch called Places and weather from the internet. It is off by default. When you turn it on, Chrysa sends a location rounded to about one kilometre, and nothing else, to two free public services: Open-Meteo for the weather and OpenStreetMap (the Overpass API) for named places nearby. No identifier goes with it. Turn the switch off and the fetched places and weather are removed.

Permissions, and why

• Usage access (Android): to show your own screen time, offer a pause when a chosen app opens, and estimate sleep. Optional; explained in the app before you are sent to the Settings switch.
• Display over other apps (Android): only so the pause can appear over the app that just opened. Optional; without it the pause is a notification.
• Physical activity (Android): the step counter, for a daily step figure and a "looks like you walked" prompt you confirm yourself.
• Calendar (Android): read-only, to keep your events out of the free blocks and show them on your day. Optional; the standard system prompt.
• Notifications: at most two a day, chosen by you, plus the pause notification when that feature is on.
• Location: foreground only, one-shot, only when you ask for nearby places or turn on the internet switch. Never in the background.

Software updates

The app checks for updates to its own code through Expo's update service. That request carries the app's version and platform, not your data.

Your controls

• Export everything as a file, in You → Privacy.
• Delete all my data, in the same place. It erases every row on the phone. Uninstalling the app does the same.
• Switch any source off at any time in You; Chrysa stops reading it even if the phone still allows it.

How to delete your data

Chrysa stores everything on your phone, so deleting it is instant and complete. Either of these removes all of it:

1. In the app, open You, scroll to Privacy, plainly, and tap Delete all my data. Every goal, log, setting, and permission record on the phone is erased at once, and the app returns to its first screen.
2. Uninstall the app. Its database is removed with it.

Nothing is kept anywhere else, so there is no retention period and nothing to request from us. The only data that ever left the phone, if you switched on places and weather, was a location rounded to about a kilometre with no identifier attached; the two public services it went to hold nothing that can be tied to you.

Children

Chrysa is for adults and is not directed at children under 13.

Changes

If this policy changes, the date at the top changes and the app's Privacy section says so.
