← back to home01 What this page covers
This page documents the procedure for deleting the data collected by Jerwis Conseil through Meta services (Facebook, Instagram), in particular:
- The events generated by the Meta Pixel installed on jerwis.fr (page view, purchase, etc.)
- The server-side events sent via the Conversions API (Purchase event after a Stripe payment)
- The matching data used to measure the effectiveness of Facebook/Instagram ads (SHA-256 hashed email, _fbp/_fbc cookies)
For other data (newsletter, invoices, etc.), see the Privacy policy, which covers all of the processing.
02 Deletion procedure
The procedure is deliberately simple. No form, no account to create, no captcha to solve:
In the body of the message, please include:
- The email address you used on the site (so I can find the matching events)
- Optional: your Facebook or Instagram ID if you want cross-deletion
- Whether you want to delete only the Meta data or delete everything (newsletter, anonymized invoices, etc.)
03 What I'll do
Within 7 business days max from receiving your request:
- Delete the Meta Pixel and Conversions API events associated with your hashed email, via the Meta Custom Audiences Removal API and the Conversions API deletion API.
- Delete the
_fbpand_fbccookies on the browser side (they'll clear automatically on expiry, at most 90 days, if you don't come back to the site). - Send a confirmation email to the address you sent the request from, with a screenshot of Meta's response.
Limits: the Meta events are also stored on Meta Platforms Inc.'s side under their own rules. Deletion on the Jerwis Conseil side does not automatically erase the data held by Meta. For full deletion at Meta, also use: Facebook Privacy Center.
04 Withdraw your consent without a specific request
If you just want to stop the tracking without filing a GDPR request:
- Decline cookies via the banner at the bottom of the page (the "Manage my cookies" link)
- Block third-party cookies in your browser (Safari and Firefox do it by default; Chrome offers a toggle in its Settings)
- Turn on an extension like uBlock Origin or Privacy Badger
- On your Meta account: Ad preferences → turn off "Activity from other websites using Meta"
05 Recourse
If you feel the deletion wasn't carried out properly or within the deadline, you can file a complaint with the CNIL, the French data protection authority.
To file a complaint directly against Meta, contact the Irish Data Protection Commission (Meta's lead authority for the EU).
