Common questions
How do I cancel my subscription or trial?
Open You, tap Account, then tap Account and billing (or Manage next to your plan). Tap Change or cancel to open the billing portal, where you can cancel.
If you subscribed through the App Store or Google Play, cancel in that store’s subscription settings instead. Either way you keep access until the end of the period you paid for.
When does my trial end, and when am I charged?
The trial is 7 days. The date it ends is shown under your plan: open You and tap Account. Your card is charged on that date unless you cancel before it. A few days before, a note on Today shows the date.
Can I get a refund?
No. Web subscriptions are not refunded. Cancel before your trial ends and you are not charged. Cancel later and you keep access until the end of the period you paid for. App Store and Google Play purchases are handled by that store under its own policy, so ask Apple or Google.
The app looks out of date.
Sinter downloads new versions in the background and switches over when you leave it. Close Sinter, then open it again.
The build date at the bottom of the Account page (open You, tap Account) shows which version you have. If you installed Sinter from the App Store or Google Play, update it there.
How do I move to a new phone?
Install Sinter on the new phone and sign in with the same account. Your data downloads on its own once you are online.
Does building a plan need the internet?
No. Build with AI uses AI when you are online and builds on your phone when you are not, so you always get a plan.
How do I export my data?
Open You and tap Your data. Export my data saves your data as a file.
Export keeps working after a subscription ends.
How do I delete my account?
Open You, tap Account, scroll to the bottom and tap Delete account, then Delete permanently. Everything is deleted at once and cannot be undone.
A web subscription is cancelled for you. An App Store or Google Play subscription is not, so cancel it in the store as well. Can’t open the app? See deleting your data.
I can't sign in, or the reset email never came.
On the sign-in screen, tap Forgot password? under the password field and enter your account email. The link can take a minute to arrive. Check your spam folder.
If you signed up with Google or Apple, use Continue with Google or Continue with Apple. There is no password to reset.
A food has the wrong numbers.
Some entries in the food database are wrong. Make your own: open Food, tap +, then tap Create under the search results and enter the label’s values per 100 g. It is kept under Saved, where you can edit it later.
