Tighten up Chrome — the 10-minute pass — schematic diagram

Before you start

Low risk. This change is reversible — you can return to the previous state without professional help or data loss.

Steps

  1. Settings → Privacy and security → Third-party cookies → 'Block third-party cookies' — kills cross-site tracking
  2. Privacy and security → Security → Safe Browsing → pick 'Enhanced protection' for real-time threat checks, not just a known-bad list
  3. Same page → Advanced → turn on 'Use secure DNS' (Cloudflare or your OS default) so your ISP can't read which sites you visit
  4. Settings → System → turn off 'Continue running background apps when Google Chrome is closed'
  5. myactivity.google.com/activity-controls → Web & App Activity → Auto-delete after 3 months — or switch it off entirely if personalization isn't worth the trail

How to verify the fix

Third-party cookies are blocked, Enhanced Safe Browsing is on, and Chrome no longer runs background apps after you close it.

If this didn't fix it

A site breaks after the cookie block — allow that specific site's cookies in Site Settings rather than reverting everything.
