How to cancel Klar by mail
Get your account details together
Before writing, collect the account email, the last four digits of the linked bank account or card and the membership tier. Klar can only act on a request it can match to an account.
Set out the request
Postbye writes the letter in Latin American Spanish from our Latin American Spanish template, because Klar's address is in Mexico. It opens with the subject line “Asunto: Solicitud de cancelación – [your name]” and asks Klar to end the subscription, stop all further charges and confirm in writing.
Send the letter by certified mail
Send the letter to the Ciudad de México mailing address shown below by certified mail. Keep the tracking number safe.
Hold on to the receipt
Keep the tracking record with your copy of the letter. If Klar 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.
Where your Klar cancellation letter goes
Written requests to Klar go to Calz Gral Mariano Escobedo 595, Piso 1, Of 01-119, Col Bosque Chapultepec I, 11580 Ciudad de México, Mexico.
Ciudad de México is in CDMX, Mexico; the postal code to quote is 11580.
Your details go in a block headed by Titular de la cuenta, Dirección de facturación registrada and Correo electrónico registrado, and the opening line is “A quien corresponda:”.

Before you cancel Klar, check these
- Ask for the direct debit or card authorisation to be ended, not only the membership.
- Investment and credit-builder products can have their own steps for closing the underlying account.
- Check your bank statement after the cancellation date for any further charge.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a finance or credit subscription
Finance and credit apps bill a membership fee through a linked account, so the request has to end the membership and the authorisation to take payments.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
