Google collects lots of data, which is used to curate content recommendations on services like Google Play and YouTube, as well as market ads to you based on your activity.

Google is rolling out a new account feature that lets you set an expiration date for your data. You can set a kill date of three or 18 months, so even if you forget to clear it out, a record of the places you visit online and in real life won’t stay around forever.

First let’s go over the data that can be automatically deleted, which Google organizes into 3 different categories:

  • Web and app history. This includes voice and audio data from Google assistant and other apps; data collected from apps synced to your Google account; all Chrome browsing history.
  • YouTube search and watch histories
  • Google Maps history and GPS location data

A more tangible reason is that deleting your data is helpful for up-to-date content (and ad) curation. People change, our tastes evolve, and periodically deleting your outdated content history is like giving your YouTube, Google Play, or even Google Podcast recommendations a refresh based on your current interests.

How to auto-delete your Google data

This process is almost identical on both mobile and web. We’ll focus on the latter, but the former is easy to figure out, too:

  1. Go to your Google activity dashboard (you’ll need to sign in to your Google account first).
  2. Click “Activity controls” from the left-hand sidebar.
  3. Scroll down to the data type you wish to manage, then select “Manage Activity.”
  4. On this next page, click on “Choose how long to keep” under the calendar icon.
  5. Select the auto-deletion time you wish (three or 18 months), or you can choose to delete your data manually.
  6. Click “Next” to save your changes.
  7. Repeat these steps for each of the types of data you want to be auto-deleted. For your Location History in particular, you’ll need to click on “Today” in the upper-left corner first, and then click on the gear icon in the lower-right corner of your screen. Then, select “Automatically delete Location History,” and pick a time.
