Restrict Chrome Browsing History Deletion & Disable Personal Google Sign-In on Managed iPads

You are better off using Microsoft Edge it has endless amounts of app configs to accomplish this.

Microsoft Edge Mobile Policy Documentation | Microsoft Learn

This is a example.

You could enroll your devices into CBCM...wait it’s called Google Chrome Enterprise Core now.  It’s free and a simple token to deploy via config profile from JAMF.  There are two settings in there you can set for this:

You can restrict browser sign-in

Turn on enable all history

There’s not any policy from anywhere to stop them from clearing the history manually (regardless of Chrome or Edge for that matter - since Edge is a re-wrappered Chrome and has the same “switches”).

Thanks! I actually have Chrome Enterprise Core set up and those policies configured, but they don't seem to have any effect on our managed iPads.

Students are still able to sign into Chrome with personal Google accounts, and they're still able to clear their browsing history.
