Terms of Use
Last updated: 21 July 2026
By downloading or using Crumb you agree to these terms. The app is provided by ZeroSix Studio.
Licence
We grant you a personal, non-exclusive, non-transferable licence to use Crumb on Apple devices you own or control, as permitted by the App Store Terms of Service. You may not copy, reverse-engineer, resell or redistribute the app.
Acceptable use
Use the app lawfully. Don’t try to disrupt it or bypass its purchase mechanisms, and don’t submit photos or questions to the AI features that you have no right to submit.
Crumb Pro subscription
Crumb is free to download, and the calculators stay free. Crumb Pro is optional and unlocks the temperature-smart schedule for every bake, unlimited AI crumb scans, multiple starters, the unlimited journal and premium recipes. Current options and prices are shown in the app and on the App Store; they vary by country and may change.
- Payment is charged to your Apple ID at confirmation of purchase.
- Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period.
- Manage or cancel any time in iOS Settings → your name → Subscriptions. Deleting the app does not cancel a subscription.
- Any unused part of a free trial is forfeited when you buy a subscription during the trial.
- Billing and refunds are handled by Apple, not by us: support.apple.com/HT204084.
- Purchases restore on a new device with the same Apple ID via Restore Purchases.
Your content
Everything you create in Crumb — bakes, starters, photos, notes — is yours, and it is stored on your device (see the Privacy Policy). Crumb has no cloud sync, so keeping a device backup is on you; deleting the app deletes your data.
Guidance, not guarantees
Schedules, timings and AI feedback are estimates based on the numbers you enter and on general baking practice. Dough is a living thing: use your own judgement, and treat oven temperatures and hot surfaces with the caution they deserve.
Availability and changes
We may update, change or discontinue features. We aim to keep the app working on currently supported iOS versions, but we don’t guarantee uninterrupted availability.
Disclaimer and liability
The app is provided “as is”, without warranties of any kind to the extent permitted by law. We are not liable for indirect or consequential damages, or for loss of data. Nothing here limits rights you have under mandatory consumer law in your country.
