Set Google activity auto-delete without losing useful history unexpectedly

A Google Account can retain activity that supports features such as recommendations and history. Auto-delete limits how long selected account activity is kept, but changing it can remove records you expected to revisit. Different activity controls and locally stored browser history are separate.

Before you start​

Sign in to the correct Google Account and decide whether you need any history for work, records or troubleshooting. Export or record needed items through Google's supported controls before choosing a shorter period.

Do it step by step​

1. Open myactivity.google.com directly and inspect a few entries to confirm you are looking at the right account.
2. Under My Google Activity, select the particular Activity control, such as Web & App Activity. Do not assume the setting covers YouTube History or Timeline too.
3. Select Auto-delete, review the available retention choices and choose the period that fits your privacy and utility needs.
4. Read the confirmation, including any activity that will be deleted immediately, then select Next and Confirm only if that is intended.
5. Reopen the control to verify the saved choice. Review other account activity categories separately and, if desired, use manual deletion for specific items.

Check the result​

The selected control should show the chosen auto-delete period. Look at My Activity later to verify older entries age out as expected; service behavior and rollout can vary.

If something goes wrong​

If the labels have changed, Google may be rolling out separate Search-service controls. Follow the current account screen and official help instead of clicking a similarly named setting blindly.

Know the limit​

Deleting Google Account activity does not necessarily clear browser history on a device or data held elsewhere. Google also notes that some activities expire sooner than the selected timeframe. Google's activity controls Google's My Activity explanation
