How to cancel Basefit by mail
Get your account details together
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Basefit is the easiest one to set aside.
Prepare the letter
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.
Post it with proof of delivery
Take the letter to the post office and ask for certified delivery to 8604 Volketswil. Keep the tracking number it gives you.
File the delivery record
It shows the date Basefit received your letter. Check your next statement: no Basefit charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Basefit, check these
- Use the same name and email as on the account. A mismatch can delay the request.
- Check your next statement: no charge should appear after the cancellation date.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
