Over time, your Android device accumulates various types of history—from browsing data to app usage - that can not only pose a privacy risk but also slow down your phone. This comprehensive guide explain what history to delete and provides step-by-step instructions on how to delete history on Android devices.

When we talk about "history", it encompasses several different data types that are stored across your Android device and associated Google Account. For optimal privacy and performance, you should consider deleting the following:
Browser History and Cache: The list of websites you've visited and the temporary files (images, scripts) saved by your browser (Chrome, Firefox, etc.). Deleting this improves privacy and frees up storage.
Google Search History: The list of queries you've entered into the Google search engine. This is often tied to your Google Account.
Google Activity History (Web & App Activity): A comprehensive record of your activity across Google services (search, Maps, YouTube) and non-Google websites/apps that use Google services.
Google Play Store Search History: The list of apps, games, movies, etc., you've searched for in the Play Store app.
Cookies: Small files stored by websites to remember your preferences and tracking data.
Sometimes, it also contains the stored passwords and autofill data, and the saved credentials and form data can be a security risk if your phone falls into the wrong hands.
Clearing browsing history and data from your Android's web browsers is a fundamental step for improving privacy and reclaiming storage space.
Delete the history of Google Chrome on Android:
Step 1: Open the Chrome app, and tap the three-dot menu in the top right corner.
Step 2: Select "History", and tap "Clear browsing data..." at the top. In the "Basic" tab, choose a "Time range" (e.g., All time).

Step 3: Ensure "Browsing history", "Cookies and site data", and "Cached images and files" are checked. Tap "Clear data". You may also want to check the Advanced tab for more options like saved passwords and autofill data.

Remove the history of Firefox on Android:
Step 1: Open the Firefox app on your Android phone, and click the three-dot menu in the bottom right corner or top right. Then choose "Settings".
Step 2: Scroll down to the "Privacy and Security" section, and click "Delete browsing data".
Step 3: Select the data you want to clear (Browsing history, Cookies, Cached images and files, etc.), and tap the "Delete browsing data" > "Delete" button.

While closely related to Google Activity, you can specifically clear the search history saved directly to your device and associated with your Google Account.
To delete Google search history on Android:
Step 1: Open the Google app on your Android device, and click your profile picture in the top-right corner.
Step 2: Select "Search history". Here, select the search history you want to remove, and click "Delete".
Step 3: Then you can select a time range. You can choose "Delete today", "Delete all time" or "Delete custom range".

Google Activity is one of the most comprehensive history records, covering Web & App Activity, Location History, and YouTube History.
To delete Google Activity history on Android:
Step 1: Browse https://myactivity.google.com/ on your Android phone, and you log in to your Google Account.
Step 2: Now you can see your activity history on the screen. Please click "Delete".
Step 3: Select a time period you want, such as "Last hour", "Last day", "All time", or "Custom range". Choose one, and your activity history during the period will be deleted.

You can also delete your search history on the Google Play Store on your Android device. However, clearing this history removes suggestions based on previous searches when you use the Play Store.
Here's how:
Step 1: Open the Google Play Store app, and tap your "Profile Picture" in the top right corner.
Step 2: Choose "Settings" > "General" > "Account and device preferences".
Step 3: Scroll down to the "History" section, and tap "Clear device search history" > "CLEAR HISTORY".
