Removing yourself, step by step

  1. 01

    Visit https://id5-sync.com/privacy in each browser and opt out of the ID5 ID.

  2. 02

    Enable Global Privacy Control in your browser.

  3. 03

    Email privacy@id5.io requesting erasure of your identifiers (include hashed email if known) under GDPR Art. 17 / state law.

  4. 04

    Keep confirmation; re-check after 30 days.

Data brokers re-list. Check again in 30–60 days.

Re-listing risk for this site: High for cookie-scoped opt-out (cleared cookies = reset); GPC helps persist per-browser.
