How to remove yourself from AdDefend
browsing-behavior and adblock-status tracking data tied to cookies on partner publisher sites — not classic name/address PII
Owner / network: AdDefend GmbH (Germany) — standalone ad-tech vendor providing anti-adblock detection/recovery for publishers; not a classic name/address data broker
Removing yourself, step by step
- 01
Visit https://www.addefend.com/en/opt-out/ in each browser you use.
- 02
Click the "Opt-Out" button (page will confirm the change).
- 03
Repeat on every device/browser combination.
- 04
Do not clear cookies afterward, or the opt-out is lost. Note: if you run an ad blocker that blocks def-platform.com, the opt-out page itself may fail to load or verify — temporarily allow that domain to complete the process.
Data brokers re-list. Check again in 30–60 days.
Re-listing risk for this site: High — the opt-out lives entirely in a browser cookie; clearing cookies, switching browsers, or switching devices silently resets you back to "not opted out"
