I turned off these Google settings to improve privacy

"I use Google for almost everything. Search, email, maps, videos, documents, even my calendar. The biggest advantage here is convenience. I don't have to create dozens of accounts and manage them separately. But it also means I'm giving way too much data to a single company. That's not exactly a smart thing to do if you care about privacy. I didn't want to abandon Google entirely, so I did the next best thing."

"If there's one Google account setting that tracks the most data, it's this one. Google's Web & App Activity setting keeps a log of what you search for, which apps you use, which websites you visit, the YouTube videos you've watched, and a lot more. Head to the Google My Activity page and you might get a shock. Almost everything you've done inside Google apps and services shows up here."

Google services consolidate search, email, maps, videos, documents, and calendar into a single account for convenience. That convenience removes the need to create and manage many accounts but concentrates a large amount of personal data with one company. Web & App Activity records searches, app usage, visited websites, YouTube viewing history, and many in-app actions. Those logs enable personalized recommendations and more relevant search results while creating extensive tracking records. Users can turn off Web & App Activity on the Google My Activity page and choose 'Turn off and delete activity here' to remove stored records. Location History (Timeline) records precise movements, visited places, routes, and trip details; disabling it stops Google from recording those movements.
