If this changes
Today, your entries are stored only on this device and are not sent anywhere. There is no account and no server for them.
If a future version offers syncing between your own devices, it will be opt-in and off until you say yes, and this page will say exactly what moves before it ships.
If the app ever counts anonymous usage beyond the page views described on this page, it will ask you first, it will stay off until you say yes, and this page will say exactly what is counted before that ships.
What we measure
We use Vercel Analytics to count anonymous page views, and Vercel Speed Insights to measure how fast pages load. These do not use cookies and do not identify you.
No journal text, mood values, energy values, or cycle dates are ever included in analytics.
The camera
Heart-rate readings are off unless you turn them on in Settings. The camera is used only while a reading is taken.
Each frame is reduced on your phone to a single colour average. No picture or video is kept, and nothing is sent. The reading is an estimate, not a medical measurement.
Voice notes
Voice notes you record are stored on this device only. Nothing is uploaded in this version.
A locked backup
The app can make a locked copy of everything you have kept here. Only your passphrase can open it. You choose where it goes, and the app never sends it anywhere. In Settings, choose Protect your data.
Export your data
In Settings, under Advanced, choose Export a readable copy to download everything as a JSON file you can keep or move. It is not locked: keep it somewhere private.
Delete everything
In Settings, choose Delete everything and confirm twice. All of your data is erased from this device and cannot be recovered.
Clearing your browser's site data for this app does the same.
Cycle data
Your cycle data stays on this device. It is never sent to a server, never shared, and never used for analytics.
