Open Settings in the app and tap Manage subscription — one tap, straight to Apple's subscription screen. You can also go to iPhone Settings → your name → Subscriptions. Cancelling stops the next renewal; Pro stays available until the period you paid for ends.
Open the app, go to Settings or the Pro screen, and tap Restore purchases. Use the same Apple ID that bought the subscription.
Settings → Export writes every medication, shot, weight entry and side effect to a CSV file and hands it to the share sheet. Pro also exports a PDF for appointments. The CSV is plain text — any spreadsheet opens it, and it is the same format the app imports.
Pro can import an export file from Shotsy and MyFitnessPal. Export from the other app first, then use Settings → Import and pick the file. Nothing is overwritten — an import can be undone straight after it runs.
Check iPhone Settings → Notifications → GLP-1 Shot Log and make sure notifications are allowed. If Focus or Do Not Disturb is on at your reminder time, iOS holds the notification back.
Deleting the app removes the on-device database and every progress photo with it. There is no copy anywhere else — export first if you want to keep your history.
