In English: If you have the Facebook app or Instagram app installed on your Android device, then Meta may have secretly collected your identity and your browsing history. This is true even if you don't have a Facebook account. It's true even if you don't use the Facebook app. It's true even if you took steps to hide your browsing history like clearing cookies or using a private browser window. On June 3rd, Meta claimed that the code responsible had "been almost complete removed"; this is [weasel wording][] which actually means "the code has not been removed". Even if Meta actually did remove the code from their apps, there are still several problems: 1. Meta has an [atrocious privacy record][]. It would be foolish to take Meta at their word and they have a strong incentive to try this again or something similar in the future. 2. Removing code does not address the information Meta has already collected. This information could be leaked in a data breach or subpoenaed by law enforcement. 3. Malicious or [trojaned][] apps could listen on the same local ports and collect the same information. The [Local Mess][] researchers demonstrated this with a proof-of-concept app. Additional privacy recommendations: 1. Prefer web sites over apps. Many services use [deceptive patterns][] to trick you into using an app instead of a web site. They do this because an app can collect more information about you than a web site. 2. Remove unused and rarely used apps. 3. Stop using Google Search. I recommend [DuckDuckGo][]. 4. [Stop using Google Chrome][ditch-chrome]. I recommend [Firefox][] with [uBlock Origin][] and some [configuration changes][firefox-privacy]. Some folks swear by [DuckDuckGo Browser][], but I haven't used it myself. See also: [The case for ditching Chrome][vox-chrome]. If you really do need Chrome or Edge, then at least install [uBlock Origin Lite][]. 5. Switch from Microsoft Windows to [Linux][]. I recommend [Ubuntu][] for new users. I use [Debian][debian]. If you really do need Windows, then at least [disable Windows telemetry][]. 6. Switch from text messaging and WhatsApp (owned by Meta) to [Signal][]. 7. Set up [Pi-hole][] on your home network. It has an easy-to-use web interface and can help block ads and tracking on mobile devices and "smart" TVs. 8. Consider [Tor Browser][] or [Tails][] if the you need more protection and are willing to accept some tradeoffs.
