Personal means personalYour body.
Your body.
Your information.
No sign-up. No health records sent to a server. VitaCycle keeps your records in the app’s private storage and excludes them from Android cloud backup and device transfer.
You can view and copy your data as JSON, or delete your local records and recovery copies from Settings. Keep any exports somewhere you trust.
Read the full privacy policy ↗VitaCycle is not a medical device and does not diagnose, treat, cure or prevent any medical condition. Predictions are estimates and must not be used for contraception. Consult a qualified healthcare professional for medical advice, diagnosis or treatment.
Before you begin.
Does VitaCycle work without internet?
Yes. Tracking, history, estimates, themes and the in-app privacy policy work offline. Fonts are included in the app, and no account is required.
What if my cycle is irregular?
You can still record your periods and check-ins. Date estimates become less reliable when cycles vary. VitaCycle shows your recorded cycle range, explains limited history, and discloses intervals excluded from its simple average.
Can I move my records to another phone?
Automatic cloud sync and data import are not included. You can view and copy a JSON export for your own records. Exported files are sensitive, and uninstalling or clearing the app can remove your local history.
Can I use predictions to prevent pregnancy?
No. Calendar estimates cannot establish when you ovulate and should not be used for contraception. Ask a qualified healthcare professional about suitable contraception.
