How To enforce Google to delete your Personal info 3 month once.

Until now, you had to manually delete this data or turn it off entirely. Deleting it means Google doesn’t always have enough information about you to make recommendations on what it thinks you’ll like, or where you might want to go.

Step 1: Visit myaccount.google.com and login if you haven’t already.

Step 2:  “Data & Personalization” on the left-side panel.

Step 3: Select the arrow next to “Web & App Activity.”

Step 4: Choose “Manage Activity.”

Step 5: Select “Choose to delete automatically.”

Step 6: Select either 18 months or three months.
