Are you sure the Android app itself is open source? I can’t find the source.

I’m pretty sure all clients base on the same javascript + html source code in this repo: https://github.com/ProtonMail/WebClient

The license seems to be MIT.

I sent protonmail an email and got this reply. Don’t think protonmail’s going to be in f-droid for a while :/

Yes I received a similar answer :
Hello,

You can find our app on the Android store. We will open-source is later this year. At the moment we don’t plan on publishing it on various Android stores, but may do so in the future.

For the official app, you can find it in the Google Play Store. Other versions in other app marketplaces may be fake, so be careful.

Best regards,
The ProtonMail Security Team

They have releases some sources, but I don’t see the Android app there:
