How to cancel Qilibri by mail
Get your account details together
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Qilibri is the easiest one to set aside.
Set out the request
Because Qilibri is dealt with in French, the letter is written in French (template fr). Subject: “Objet : Demande d'annulation – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Send it by certified mail
Send the letter to the Paris mailing address shown below by certified mail. Keep the tracking number safe.
Hold on to the receipt
It shows the date Qilibri received your letter. Check your next statement: no Qilibri charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Qilibri cancellation letter goes
For a letter to Qilibri, use Rue Réaumur 81, 75002 Paris, France.
The envelope is going to Paris in Île-de-France, France, so the postcode 75002 must be on the front.
Your details go in a block headed by Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré, and the opening line is “À qui de droit,”.

Before you cancel Qilibri, check these
- Use the same name and email as on the account. A mismatch can delay the request.
- 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.

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 letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
