How to cancel Fitinn by mail
Start with your account details
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 Fitinn is the easiest one to set aside.
Draft the request
Fitinn is based in Austria, so the letter goes out in German, built from our German template. Subject line: “Betreff: Kündigungsanfrage – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Post it with proof of delivery
Take the letter to the post office and ask for certified delivery to 1120 Wien. Keep the tracking number it gives you.
Keep proof the letter arrived
File the receipt with the letter. A Fitinn charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Fitinn cancellation letter goes
Fitinn lists Edelsinnstraße 4, 3 stock, 1120 Wien, Austria as its mailing address.
Copy the postal code 1120 exactly: it is what routes the letter to Wien, Austria.
Your name, address and email appear in a short block labelled Kontoinhaber, Hinterlegte Rechnungsadresse and Hinterlegte E-Mail-Adresse, under the greeting “Sehr geehrte Damen und Herren,”.

Before you cancel Fitinn, 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
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
