DuckDuckGo has privacy already setup, vs Fennec/Firefox can do the same but you need to do your own research to know what Add Ons will make them as good as DuckDuckGo. Also keep in mind that Fennec is Open Source which is a good place to start. The do some searches to see what AddOns will that it up to DuckDuckGo level. Plus DuckDuckGo is an AddOn fro Fennec and that might bring it all together. I use Fennec and FireFox because I love the way it handles passwords and everything can be Synced between Fennec for Android and FireFox for PC. If your serious about privacy get free or premium ProtonMail which has Calendar, Contacts, Drive Beta, all encrypted, plus free or premium ProtonVPN, also free and open source encrypted messaging is Silence, built with same security as Signal but without all the silly stuff that Signal is going to. Also another Open Source on droid to replace android, is Simple Mobile which has a suite of de- googled apps such as, well, everything basic phone function. Camera, notes, photo editor, their website highlights all their de-googled apps.
I use ProtonMail, Calendar, Contacts, Drive (beta), VPN, they have a free version of everything for casual users and paid for heavy users. ProtonVPN is located on fdroid and ProtonMail includes everything else. There are Apps for iPhone and Android plus can be browser accessed. Everything is locked down and encrypted. Drive is a work in process.
GrapheneOS is the best as it severely degoggles and is best at security and privacy. It only uses Google Pixel phones that are not sold through carriers. LineageOS degoogles but is lax on security, especially that it doesn’t lock boot. It is an oxymoron to say you want to degoogle and than add microG. With GrapheneOS you’ll start with just the basic phone functions and they are all secured, from there you can go to Fdroid and download more and I suggest looking at Simple Mobile suite of apps in fdroid. OsmAnd~ is an actual fdroid open source turn by turn map/guidance app.
Yes, indeed, another wonderful day!
