I would prefer being able to use KeepassDX on my mobile (I assume you meant that), but I got burnt trying to use that while syncing my database through my Nextcloud. KDX does not check for external changes before overwriting the database, and with background-sync being as unreliable as it is on android, I have lost a few passwords that way without noticing it.

Why do you need search category data to develop a browser?

I too think that it would be better for everyone if the USA was cut off from technology.

Personally I'd just use Librewolf then

Why would you use mullvad browser if you're not going to use mullvad vpn?

True, I wasn't aware. Free accounts get deactivated after 6 months without login. They can only be reactivated using a paid account and the correct credentials.

Tuta.io maybe

Cannot confirm. If I type in anything between "fdr" and "fdroid" it brings up F-droid for me.

Niagara Launcher is not FOSS, it's closed-source. If you want an open-source search-based launcher, there are Kvaesitso and KISS Launcher for example

I'm not sure if that helps you, but there are plenty of search focused launchers for android that let you add keywords as tags to apps as well like KISS Launcher and Kvaesitso

While I personally use KeepassXC and Keepass2Android on mobile devices (as with KeepassDX there is no reliable way of syncing the database that I know of) to other less tech-inclined people I'd always recommend Bitwarden as it is much more suitable to most people's usecases.

What kind of maniac posts a screenshot of their code instead of the code itself to ask for help tho
