No, not that I’m aware of. And I think that would be meaningless to 99.8% of users. It’s not like you can filter your searches anyway.

If people DID start thinking of it as some kind of sealer quality, unscrupulous actors would simply open source their apps and leave all the garbage in. So it would become meaningless.

Further, what does it being open source help? They could publish the app source without the tracking SDKs (especially as some of them are big enough now that you have to hassle with git-lfs even if you wanted to commit it) and then build it with the tracking SDKs before submitting to the App Store.

Other people could build these apps at build farm and publish under trusted vendor name like linux distributions do. You don’t trust vim.deb from anyone, but e.g. vim.org and ftp.??.debian.org/debian have at least strictly no intent to abuse you.

You realize we are talking about iOS / the App Store, right?

Apple has removed GPL-licensed apps from their store.

No but open source apps will usually tell you in their description.
