Notifications aren't firing
Reminders are available in the native iOS app, not the browser version. For the native app, check iOS Settings > Marcy > Notifications and make sure Allow Notifications is on.
Backing up or moving your data
Go to the data page and tap “export backup” to save your data as a file. If you reinstall the app or switch devices, use “import backup” to restore it. There is no account or cloud sync — the backup file is the only copy outside your device.
Deleting your data
Use “fresh start” on the Data page and confirm “erase data” to remove local history, settings, and recovery copies and cancel pending reminders. Downloaded backups are not deleted, and this does not remove an email address already submitted for product updates.
Predictions look off
Marcy starts with a 28-day default and uses eligible intervals between logged periods to estimate cycle length. You can also set it manually. Timing remains estimated, even with more history.
Small shifts are normal. Marcy helps you recognize patterns, even when cycles vary by a few days. Use its estimates as a starting point, alongside what she notices and shares with you. Larger changes in cycle timing can make estimates less reliable. Marcy does not confirm ovulation, and its daily guidance may not match everyone’s experience.
