I've been trying to keep everything stripped down on my new Pixel with GrapheneOS. I'm basically avoiding apps with sneaky permissions and anything Google. However, I wanted to use an independent mail client because I sadly have a particular gmail account that I use quite often. I am testing out Thunderbird right now. And it works flawlessly. But trying to search anywhere else online in an attempt to find out if Thunderbird is truly safe or not just doesn't pan out. I'll leave it at that so I don't sound too harsh.
Can any Devs or people with experience vouch for this program or give me a legit reason to uninstall it? They claim open source and "privacy focused"...But that's basically like saying "all natural" in the 21st century.
I appreciate any input.
