@Edent the best option, when possible, is not to use apps created by institutions that have reason to sell you out, but to use their websites instead. this typically sidesteps the listed security concerns while also protecting your privacy from the relentless analytics + lowkey (or not-so-lowkey) spyware included in so many apps on android (and on most other platforms).

apps on android can track you in many more ways than even their "permissions" would imply, and google's measures to limit these have been inadequate.
