Was shocked to see Bitwarden is tracking? Any explanation as to why?
Your answer lies in the Security FAQs here:
You can also disable crash reporting in the settings menu.
In the mobile apps, Firebase Cloud Messaging (often mistaken for a tracker) is used only for push notifications related to sync and performs absolutely no tracking functions. Microsoft Visual Studio App Center is used for crash reporting on a range of mobile devices. In the web vault, Stripe and PayPal scripts are used for payment processing only on payment pages.
For those who prefer to exclude all 3rd party communication, Firebase and Microsoft Visual Studio App Center are removed completely from the F-Droid build. Additionally, turning off push notifications on a self-hosted Bitwarden server will disable using the push relay server.
Thanks for the responses. Somehow I missed it in the FAQ.
