Quick answer

On One UI 8.5, Customization Service is under Settings, General management, near the bottom of the page. Samsung's privacy notice still says Settings, Privacy, but on our One UI 8.5 phone it was no longer listed there. Tap it to see whether it is on and to turn it off.

Your Galaxy runs an older One UI. Samsung's own privacy notice gives the older place: Settings, Privacy.

About this guide

Customization Service is the Samsung account feature that uses data from your phone to personalise content and ads. On One UI 8.5 it moved, so the path in older guides and in Samsung's own notice leads nowhere.

Good to know

Samsung's privacy notice says the service can use information such as your apps, location and browsing to build a profile for recommendations and, with consent, ads. It runs through your Samsung account.

Fewer personalised ads from Google as well: how to reset or delete the advertising ID on a Samsung Galaxy.

In short: One UI 8.5: Settings, General management, Customization Service. No longer under Privacy.
