Indeed. They offer up the original .apks from their respective github sources, so generally don’t include trackers etc as you’d find on the Google store versions, or even f-droid at times.

Same can be achieved with Proton, which accept Bitcoin. Bitcoin is pseudonymous, so just buy on a DEX/P2P, and transact, there will be no link to your PII. Buying on a CEX links to PII.

Use Obtanium or Zapstore to get the non-Google and non-F-Droid .apk, as those contain trackers for the notification system to work.

Metal Gear (Solid) series, Legacy of Kain series.

Also Spider-Man: Web of Shadows, and Sacred (1&2).

I revisit all these on a rotating basis from time to time.
