How to cancel Ai Fitness by mail
Get your account details together
Start with the account email, the plan or product name and the invoice or order number from your latest receipt, so the request to Ai Fitness names the right account the first time.
Write your request
Postbye writes the letter in German from our German template, because Ai Fitness's address is in Germany. It opens with the subject line “Betreff: Kündigungsanfrage – [your name]” and asks Ai Fitness to end the subscription, stop all further charges and confirm in writing.
Post it with proof of delivery
Use certified mail for the 47803 Krefeld address in the next section, so the post office records the delivery. Write down the tracking number.
Save the tracking record
File the receipt with the letter. A Ai Fitness 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 Ai Fitness cancellation letter goes
Ai Fitness takes its post at Gutenbergstraße 152, 47803 Krefeld, Germany, which is where a cancellation letter belongs.
Copy the postal code 47803 exactly: it is what routes the letter to Nordrhein-Westfalen, Germany.
Your details go in a block headed by Kontoinhaber, Hinterlegte Rechnungsadresse and Hinterlegte E-Mail-Adresse, and the opening line is “Sehr geehrte Damen und Herren,”.

Cancelling a software or app subscription
Software plans are billed per plan or per seat, often yearly, and the app store version is billed by the store rather than the developer, so the request has to name the plan and who bills it.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
