Where is my migraine data stored?
Migraine records stay in HeadKind's protected container on your iPhone. HeadKind has no account or cloud health record. You can create a PDF or JSON archive from Settings when you want a copy.
How do I restore HeadKind Pro?
Open HeadKind Settings and choose Restore Purchases. Use the same Apple Account that made the original purchase. You can manage or cancel the subscription from the same section.
Why did a reminder not appear?
Check HeadKind Settings to confirm reminders are enabled, then open iPhone Settings → Notifications → HeadKind and allow notifications. Focus modes and scheduled summaries can also delay a reminder.
How do I delete my data?
Delete a migraine from its History detail, or use Delete all data in HeadKind Settings. Deletion is permanent unless you exported a copy. The two-migraine free allowance is not reset by deletion.
