How to cancel G Data by mail
Get your account details together
G Data will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Draft the request
Because G Data is dealt with in German, the letter is written in German (template de). Subject: “Betreff: Kündigungsanfrage – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Post it with proof of delivery
Send the letter to the Bochum mailing address shown below by certified mail. Keep the tracking number safe.
File the delivery record
File the receipt with the letter. A G Data 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 G Data cancellation letter goes
G Data lists Königsallee 178 a, 44799 Bochum, Germany as its mailing address.
Copy the postal code 44799 exactly: it is what routes the letter to Nordrhein-Westfalen, Germany.
Inside, the salutation reads “Sehr geehrte Damen und Herren,”, followed by your details under Kontoinhaber, Hinterlegte Rechnungsadresse and Hinterlegte E-Mail-Adresse.

Before you cancel G Data, check these
- 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.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
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 subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
