Draft the request
The request is prepared in German (template de), under the subject line “Betreff: Kündigungsanfrage – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Send the letter by certified mail
Use certified mail for the 68309 Mannheim address in the next section, so the post office records the delivery. Write down the tracking number.
Keep the proof of delivery

With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Fitbase, check these
- 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.
- Use the same name and email as on the account. A mismatch can delay the request.
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

A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
