Any update? This was posted in 2016. If it was genuinely "planned" it would be done already...

Protonmail claims to be privacy first. How can you require us to install Google's spyware on our phones?

Please, provide the APK so people don't download random APKs from insecure sources!

Or even better, provide a bridge for Android so we can use our favourite mail client and don't have to use a different app at all.

I am in the process of moving to ProtonMail, but having recently changed phone OS, this is really making me think twice! Unfortunate as ProtonMail has otherwise been great

I cant even open my protonmail app now without updating it. Where is the direct download for the apk?
Google IS the problem. How do we know you are true to your statements about privacy when you use one of the most intrusive spies in the world?

Seriously, Google has been
getting fines from all over because of their practices. They don't respect anyones privacy.

I liked the app, but I guess rhis is the end of the app. I am not going to give Google even more info than what they have already covertly gathered on me.

ID theft is a big enough problem in the US. If you really did go to MIT you would know this.

Need push notifications without Google services !

Hello,
The Tutanota app works very fine without the google system framework. It's available in the f-droid repository, so no dependency to Google whatsoever. It is imho more or less a (little) JOKE that Protonmail (security and privacy for the user??) when it depends on Google services. When Tutanota can, Protonmail should also be able to ditch Geegle dependency. I now use the slow protonmail mobile website login on my phone (Lineage/ViperOS without google system framework). I am thinking about moving all my e-mail to Tutanota...).

Tutanota has removed Google dependencies on their email app. Why cant ProtonMail?

F-Droid recommends to uninstall my application because it will be removed from F-Droid: f-droid.org package-Droid relies on the standard tools for verifying the signatures of APKs, Know more at https://www.brotherprintersupportnumber.com/blog/how-to-fix-brother-printer-offline-status-error-on-windows-10/

+1. Please remove GAPPS depency and provide apk. many thanks.

@65801207-the-protonmail-team Please re-open this idea for votes.

The Pushy team answered some questions for me, here are some specifics:

1. Encryption for Push notifications? Pushy Pro plan uses plaintext MQTT to deliver notifications downstream to devices. Their Enterprise plan however is fully TLS encrypted in all communications to and from Pushy, including your servers to theirs

2. Opensource? The Enterprise plan Some parts of their service is open source, others are not. Mostly their client SDKs are open source (but not the core Android SDK)

Use Pushy. It is a replacement for GCM but each app developer must manually embed Pushy in their apps. Pushy cannot itself be flashed onto a non-GMS phone to replace GCM.

Protonmail app development should support devices without GMS, you can embed the Pushy SDK in your app and it will work on these devices, instead of using GCM.

In the fight for privacy why not open a page on Diaspora* or Mastodon and Delete your Facebook and Google+ page.

Implementation or further work towards imap support for usage of clients such as K9 mail would be beneficial and would aid to the goal or removal of the dependence of google's push service.

im currently working on a temp. fix for getting notifications to work with nothing but fdroid resources and microg.

As far as I've understood, the only usage of GSF is for push notifications.
My phone does not have GSF installed, and the only annoyances are the message on start and the fact that e-mails are not synced in the background. I see that this "feature" is planned, but it has been planned for almost 2 years. I think someone should definitely start working on it....

These are the guys who are abusing our privacy, and why I came to ProtonMail to begin with. It is kind of silly for you to be offering a great privacy product, but then steer us to the greatest abusers of privacy in the world. I would not want to see any links to Facebook or Google at ProtonMail.

As a contributor to Protonmail, I find quite hilarious how dependent it is on Google and it's services. Why on earth would I want Google to keep a registry of my downloaded apps? Not to talk about other 'features' in the app, which apparently need Google to function?
Even though APKs can be found in the wild, it would be nice to get it from a centralized and trusted source like F-Droid. Makes upgrading easier too...
