As someone running a TestFlight beta, I can tell you: that’s not true. TF captures the AppleID used to sign up and how many times the app is opened and crashed, but, unless you set the app to collect other personal details (major red flag), the only other thing a Lemmy client should store is login details and app preferences.
Are you saying that your Lemmy client is mining personal data from users phones? Why in the world would you do that?
Edit: TF betas can also be configured for signups via a link, so that users emails are not captured by TF, and AppStore Connect only registers the users as “Anonymous”. This is how we do it. The only user emails we capture are those in our internal test group— the developers themselves.
its back up, btw
