Cache Out - A Privacy Focused Free Tool For Multiple Browsers

Mac Apps

Cache Out, a free new single-purpose utility from veteran Mac developer Jim Mitchell, fits right into an app category that is severely underrepresented - utilities that work across multiple browsers from a single interface.

What It Does

Cache Out's superpower is selective data removal from a variety of popular macOS browsers with the click of a single button. It removes five categories of information - cache, history, downloads, favicons, and cookies. You select the browsers you want cleared from a list. You select the categories of data to remove. Then, you click a single button and BOOM. It's done. After the files are removed, you aren't left in the dark about what happened since you get a report on the number of files and MBs that were removed.

There are currently seven supported browsers:

  • Safari
  • Chrome
  • Firefox
  • Edge
  • Brave
  • Opera
  • Orion

I'd like to see a few more on the list, including Vivaldi, Arc, and Atlas. Thankfully, Mitchell indicates that more browsers are coming.

Cache Out punches all the right buttons for a privacy-focused app. It doesn't phone home or collect analytics. It doesn't require an account or registration. It's Apple-notarized. Everything happens on your machine.

Why You Need It

Don't think that an app like this is the ultimate Boss Button. Most corporate-owned computers track Internet traffic in real time, so your IT department can still track your history if this is your only precaution. Still, most undermanned and overworked support workers don't care where you go as a general rule. Likewise, your home ISP can track your DNS requests for almost every site you visit unless you use a no-log VPN or a service like NextDNS that offers name resolution over HTTPS. Even then, you have to be savvy enough to set it up correctly.

Still, there are a lot of reasons for running clean browsers. In a world where browser fingerprinting is maximally invasive and pervasive, one defense is using multiple browsers to make yourself harder to track for the data scrapers of the world. You'll quickly build up GBs of data for almost every browser you use. If you're stuck with a small hard drive you can't upgrade (like my brand-new M4 Mac Mini's 256GB), you always have to be careful with space. Cache Out is the perfect app to do that.

Also, many countries, including my own, are seeing a rollback of civil liberties. To make matters worse, areas where people travel with their computers offer less privacy than you'd have at home. If you gave the slightest concern about the TSA, ICE, or the CBP looking through your browser history, use Cache Out before you travel.
