Guest mode
Guest mode saves cycles 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. Local data is not automatically uploaded.
Account mode
If you create an optional account, future saved cycle estimates 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. 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 are not silently moved to Supabase. If you log in and local cycles exist, the dashboard asks before importing them 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 saved cycles as JSON from data controls. You can delete individual saved cycles 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.
