How to cancel Allsecur by mail
Gather your account details
Allsecur 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
Postbye writes the letter in French from our French template, because Allsecur's address is in France. It opens with the subject line “Objet : Demande d'annulation – [your name]” and asks Allsecur to end the subscription, stop all further charges and confirm in writing.
Send it by certified mail
Take the letter to the post office and ask for certified delivery to 92087 La Défense. Keep the tracking number it gives you.
Keep proof the letter arrived
Once the letter is delivered, the date on the receipt is the date Allsecur was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Allsecur cancellation letter goes
Written requests to Allsecur go to TSA 90001, 92087 La Défense, France.
“TSA 90001” is a post-office box or mail-sorting line, so it takes post and not couriers: certified mail is the right way to reach it.
The letter greets the reader with “À qui de droit,”; your own details sit under the labels Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

Before you cancel Allsecur, check these
- 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.
- Check your next statement: no charge should appear after the cancellation date.
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
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
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.
