Lumo AI, Proton newest #privacy product has a hard dependency on Google Play Services, so it won’t work on GrapheneOS or CalyxOS.

No APK is provided too, meaning you can’t download the app from GitHub, Obtanium, or F‑Droid—you’re forced to get it from the Google Play Store. The same thing happened with Proton Wallet.

People can’t honestly tell if it's sheer incompetence or a deliberate honeypot.
