No Molly, an independent Signal fork for Android, listing? Among other things, Molly handles data encryption at rest better and also has Tor support...which your spreadsheet doesn't even list Tor support.

I can understand not wanting to including Molly due to it being only on Android (though I think/hope a lot of privacy enthusiasts run GrapheneOS on Pixels) even though it currently rides the Signal servers so in compatible with other Signal clients, but at least add Tor compatibility, please.

Still using Google fonts for this spreadsheet ? Why ?

Is there no Google Sheets alternative that would allow to display it without having to download?

Also, there's not a lot of value in placing it on GitHub if you can't even preview the changes of a submitted pull request.

Fix your readme and give a use case for how to use this git repo

Still very biased towards Matrix Vs XMPP when it comes to encryption. If it is "provider specific" for XMPP it should be also "provider specific" for Matrix... or rather in 99% of the cases it is not "provider specific" at all but available and enabled by default for both. That there are a few non-compliant server+client combinations is just a result of an open-source and decentralized network.

Edit: same for the "what apps can hand over to police section", which is also highly provider specific as it doesn't really concern the "app" but rather the server (which can be self-hosted).

For matrix there is a no for client removes image metadata. Did you check all clients? I would imagine it was client dependent.

Here is a good overview. You could compare this with your findings:

Please just focus on messaging apps. That's a big enough task.

do one thing and do it well

There is a typo: Three O's in "Outlook". Also, please add a row for services that include padded encrypted messages. Love this project!

Edit before I get shot down: I am aware the repo says "If you see errors or would like something added, please submit an issue here.", but Github is not private and therefor I will not create an account. Apologies for the inconvenience.
