Stempel Support
Stempel is designed to work without setup or an account. If something does not behave as expected, these are the fastest places to start.
Contact support
Tell us what happened, what you expected, your iPhone or iPad model, your iOS or iPadOS version, and the Stempel version shown in Settings. Screenshots are helpful when available.

Timer, widgets, and Live Activities
Open Stempel once after installation so its widgets and Shortcuts can register. If a widget does not refresh, open the app, confirm the timer state, and remove and add the widget again. Live Activities also need to be allowed in iOS Settings.
iCloud synchronization
Confirm that your devices use the same Apple ID, iCloud Drive is available, and iCloud Sync is enabled in Stempel Settings. If iCloud is unavailable, records continue to save locally. Reopen Stempel after the service returns; if the status still shows unavailable, turn iCloud Sync off and on again.
CSV import and export
Use Settings → Data to export all records or import a Stempel CSV. A valid file uses the header: date, start, end, duration_seconds, note. Keep a copy of important exports in Files or another destination you control.
Purchases and Family Sharing
Stempel is a paid App Store download with no in-app purchases or subscription. Apple handles downloads, purchase history, refunds, and Family Sharing. For account or billing issues, contact Apple Support.
