For android I tend to like Safe Notes. It’s relatively simple, encrypted with either passphrase or biometrics, and stored locally, with a way to back up to a file. Just make sure you memorize/save the passphrase so you don’t lose your entries. It’s android only though, if that matters. I only use it for shorter stuff, so I’m not sure how well it works for longer entries.

I haven’t used Chameleon, but it seems to do some stuff like change the user agent that JShelter doesn’t do. I’d assume it’s more useful to get around a site designed for a specific browser or operating system.

JShelter isn’t mainly for spoofing, it’s about blocking a bunch of potentially harmful advanced javascript features, often used for tracking. Any spoofing is mostly to keep sites working with the missing javascript features.

I have it installed on one of my browsers. I wouldn’t recommend using it unless you’re willing to tweak the settings for new sites you visit, because I’ve had it break sites pretty often with the default settings.

There’s also Arity. It isn’t the best interface, but it has functions, variables, and graphs.

I was also using Unitto for unit conversions, but apparently the creator doesn’t want forks or for f-droid to host it, so I’m looking for another one.

They’re not browsers, but if you want lemmy in the terminal there’s Neon Modem Overdrive, which also handles Discourse forums and some other sites. For emacs there’s lem.el.

There’s also clauses about revoking your license if you try to sue them, and how you need to still include the system to pay them in your modified version.

I’m pretty sure most screen readers and stuff like copy/paste would also get whatever nonsense you filled it with.

A lot of the ways they scrape documents are the same used by accessibility tools, so I’d generally recommend against doing this.

It was a term for modded crappy japanese motorcycles and cars, that derived from a slur for asian people.
