Out of the box, Chrome tracks more than it needs to and keeps running apps after you close it. Ten toggles fix most of it.

What that means

Low risk. This fix only checks things, or changes settings you can switch back in the same place. This change is reversible — you can return to the previous state without professional help or data loss.

Steps

01
- Settings → Privacy and security → Third-party cookies → 'Block third-party cookies' — kills cross-site tracking
02
- Privacy and security → Security → Safe Browsing → pick 'Enhanced protection' for real-time threat checks, not just a known-bad list
03
- Same pageAdvancedturn on 'Use secure DNS'(Cloudflare or your OS default) so your ISP can't read which sites you visit
04
- Settings → System → turn off 'Continue running background apps when Google Chrome is closed'
05
- myactivity.google.com/activity-controlsWeb & App ActivityAuto-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.
