How to cancel Empiricus by mail
Get your account details together
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Empiricus names the right account the first time.
Draft the request
Empiricus is based in Brazil, so the letter goes out in Brazilian Portuguese, built from our Brazilian Portuguese template. Subject line: “Assunto: Solicitação de cancelamento – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Mail it with tracking
Mail the letter by certified mail to the São Paulo address in the next section, and keep the tracking number.
Hold on to the receipt
Keep the tracking record with your copy of the letter. If Empiricus 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 Empiricus, 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
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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
