Note your account details
You will need the name and email on the account and, if you have one, an account or customer number. Use exactly the details Katapult holds, so the request can be matched to your account.
Put the request in writing
Postbye drafts the request in German, the language of Germany, with “Betreff: Kündigungsanfrage – [your name]” as the subject line. It asks Katapult to close the subscription, stop billing and confirm in writing.

Keep proof the letter arrived
Once the letter is delivered, the date on the receipt is the date Katapult was told. Compare it with your statements over the next billing cycle.

Before you cancel Katapult, check these
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
