How to cancel Adapta One by mail
Find your account details
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Adapta One names the right account the first time.
Put the request in writing
Postbye writes the letter in Brazilian Portuguese from our Brazilian Portuguese template, because Adapta One's address is in Brazil. It opens with the subject line “Assunto: Solicitação de cancelamento – [your name]” and asks Adapta One to end the subscription, stop all further charges and confirm in writing.
Send the letter by certified mail
Send it certified to São Paulo, Brazil, copying the address from the next section letter for letter, and keep the receipt slip.
Keep the proof of delivery
Keep the tracking record with your copy of the letter. If Adapta One bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Adapta One, 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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
