How to cancel Klay by mail
Note your account details
Klay will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Prepare the letter
The request is prepared in French (template fr), under the subject line “Objet : Demande d'annulation – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Mail it with tracking
Post it by certified mail to Klay in Paris, France, using the exact address below, and note the tracking number.
Save the tracking record
It shows the date Klay received your letter. Check your next statement: no Klay charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Klay cancellation letter goes
Klay takes its post at Rue Saint-Sauveur 4bis, 75002 Paris, France, which is where a cancellation letter belongs.
The postcode 75002 belongs to Île-de-France, France, so this is where the envelope is delivered.
Your name, address and email appear in a short block labelled Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré, under the greeting “À qui de droit,”.

Before you cancel Klay, check these
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- 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.
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.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
