How to cancel Languagetool Premium by mail
Find your account details
Put the account email, the plan or product name and the invoice or order number from your latest receipt in front of you before you write: the request to Languagetool Premium is only as good as the details it quotes.
Prepare the letter
Postbye writes the letter in German from our German template, because Languagetool Premium's address is in Germany. It opens with the subject line “Betreff: Kündigungsanfrage – [your name]” and asks Languagetool Premium to end the subscription, stop all further charges and confirm in writing.
Mail it with tracking
Take the letter to the post office and ask for certified delivery to 14482 Potsdam. Keep the tracking number it gives you.
Hold on to the receipt
It shows the date Languagetool Premium received your letter. Check your next statement: no Languagetool Premium charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

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