In offering these privacy tools, Google is a step ahead of other internet giants like Facebook and Twitter, which don’t provide ways to easily delete large batches of dated posts.
Yet there’s no one-size-fits-all for how people should use Google’s privacy controls, since everyone has different lifestyles and levels of paranoia. To give an idea of how you can tailor these settings, here’s my personal setup:
I set my search history to auto-delete. I rarely use Google Assistant and don’t visit Google News, meaning I don’t benefit from personalized recommendations. But I’m often checking Google Maps, and it’s useful to have a recent history of those searches to revisit destinations. So I set Web & App Activity to automatically delete after three months.
I set my YouTube history to self-destruct. I go in and out of phases that involve cooking different types of foods, and I like it when YouTube surfaces new recipes based on recent searches. So I set my YouTube history to auto-delete after three months.
I set my location history to auto-delete, too. I use Google Maps regularly, and I go on big trips twice a year. It’s useful for me to let Google know where I have been recently so that its Maps app can load relevant addresses and remember places I have been. But it’s not useful for Google to continue to know that I went to Hawaii last month for vacation. So I set my location history to auto-purge after three months.
It’s difficult to imagine why anyone wouldn’t want to take advantage of Google’s auto-delete tools. There’s no practical benefit to letting Google keep a history of our online activities from years back. So don’t delay in wiping a tiny bit of your digital traces away.
