Private by design
Your health data belongs to you
Jandost works on your phone first. Cloud sync is optional, and you can download or permanently delete everything at any time.
About privacyEncrypted on your phone
The local database uses SQLCipher (AES-256) with a key kept in the phone’s secure keystore.
Encrypted on the server
Sensitive fields are encrypted at the field level; traffic is HTTPS only.
Offline, always
Everything works without internet; sync catches up when you reconnect.
You decide
Cycle data syncs only with your explicit consent and is never shared with anyone.

Frequently asked questions
Is Jandost free?
Yes. Logging, charts, reminders, reports and sync are free. No ads, and we never sell data.
Do I need an account?
No. The app works fully without one. An account is only needed for backup, syncing between devices and the web dashboard.
Which devices does it work with?
Android and iOS. Steps, sleep and heart rate import from Health Connect and Apple Health, and glucose sensors are scanned over NFC.
Does it replace my doctor?
No. Jandost is a logging and tracking tool and gives no treatment advice. Make treatment decisions with your doctor.
What if I change phones?
Sign in on the new phone and all your data and settings come back.
How do I delete my data?
Use “Delete account” in the app or web dashboard. After 30 days, everything is permanently erased from the server.
