What you can do to reduce being targeted

Use browser privacy modes, block third-party cookies, and use privacy extensions (uBlock Origin, Privacy Badger).
Opt out of ad personalization: Google Ad Settings, Apple/Android ad ID reset & limit ad tracking.
Use tracker-blocking browsers (Brave, Firefox with strict tracking protection) or a VPN.
Exercise privacy rights under local laws (CCPA/GDPR) to request deletion or opt-out.
