Guest mode
Guest mode saves cycle estimates and actual period records only in this browser on this device. No account is required, and guest history does not sync across browsers or devices.
Privacy
Choose local privacy or optional account history.
Guest mode stores saved cycles only in this browser on this device. Account mode stores saved cycle estimates in Supabase when you are signed in and can store actual period records for adaptive cycle-based estimates. Local data is not automatically uploaded.
Account mode
If you create an optional account, future saved cycle estimates and actual period records can be stored in Supabase so you can view account history across devices after logging in.
What saving stores
Saved cycles include calculator inputs, estimate results, confidence, warnings, and created date. Actual period records include period start date, optional period end date, quality flags, and visible caution notes. Account mode also stores the authenticated user ID needed to keep each record private to that account.
Local data is not auto-uploaded
Local guest cycles and actual period records are not silently moved to Supabase. If you log in and local data exists, the dashboard asks before importing it to your account.
What is not stored
The app does not store partner details, payment details, GP or clinic details, lab results, wearable data, uploaded files, intercourse logs, or free-text medical notes.
Exporting and clearing saved cycles
You can export local or cloud fertility data as JSON from data controls. You can delete individual saved cycles and actual period records from the dashboard or clear all local or account fertility data from data controls.
Account deletion is separate
Deleting fertility data does not delete your login email or authentication account. Signed-in users can request account deletion from data controls through a server-side flow that requires re-authentication and typing DELETE.
