> only with trusted code

That's a big assumption. Have you read all the code, and the dependencies of the dependencies of your code? If you haven't, how do you know it can be trusted? What if there is a backdoor in an obscure dependency that can inject a script into your website to steal your sensitive data? Don't laugh it off. When there is money on the line, someone is going to try it.

What about the extensions you installed in your browser? What about the user scripts (if you use them)?

> Huh? Please don't do this, especially not for "local first" applications, would defeat the entire purpose.

Why not? Why do you want a local first app in the first place? What's the purpose of a local first app, if not security?

I think you're misunderstanding what kind of application this is.

It's not a website, it doesn't run in your normal browser. It runs as a standalone application.

Because as soon as those keys aren't available (either because the endpoint no longer exists, or you cannot connect to the endpoint for whatever reason (like being offline)), you can no longer access your data.

That isn't "local first" at all, it's something else entirely.

The encryption key doesn't have to be stored in the cloud. It just has to be stored somewhere else -- it could be in the file system.

Even if it's a standalone application, it doesn't mean the code can be entirely trusted. I wouldn't take that risk.

Right, makes sense. I was saying to not store it in the cloud, specifically. Encrypt local data at rest, makes sense. Storing encryption keys for said content somewhere where you need internet access to get, doesn't make much sense.

"Trusted" here refers to "not user provided inputs" that SaaS/website usually does somewhere. Obviously, there is code somewhere that you haven't read and verified, that's true for literally everyone using a computer today, no one has read and verified all the code they've run, we'd get nothing done if that was common practice.

Just for curiosities sake, what OS you use and how much of your software you use daily have you read through the source code of?

Very few. It depends on the data I need to store in the program. I don't store sensitive data in Figma or VSCode, so I don't really care if they don't encrypt my data in local storage. But if I'm in the market for something that offers to manage my sensitive financial data, then yes, I want to dig into its dependencies and security strategy first.
