To get a fast answer, include your iPhone model, your iOS version, the app version (Settings → About in the app), and what you expected to happen.
My notifications never arrive
Check iOS Settings → Notifications → Crumb and make sure alerts are allowed, then open the bake and confirm reminders are switched on for it — a bake started with reminders off shows a banner offering to turn them on. Focus modes and Low Power Mode can also delay delivery.
Restore a subscription
Open Crumb → Settings → Restore Purchases, signed in with the Apple ID that made the purchase. If it still doesn’t appear, email us the date of purchase and we’ll help.
Cancel a subscription
iOS Settings → your name → Subscriptions → Crumb → Cancel. Apple handles billing and refunds (support.apple.com/HT204084). Deleting the app does not cancel a subscription.
The schedule doesn’t match my kitchen
Crumb re-times the remaining stages from the dough temperature you log, so log it again whenever it changes — after mixing, and once during bulk. If your kitchen runs persistently cold or warm, the plan will shift accordingly rather than sticking to the recipe’s fixed hours.
Export or delete my data
Bakes and starters can be deleted individually in the app. Everything is stored on your device, so deleting the app removes all of it. If you want a copy of a bake, use the share action on the bake to send it out as text and photos.
Report a bug or request a feature
Email us — feature requests genuinely shape the roadmap, and several shipped features started as one message.
