This has been a pet project I've chipped away at here and there for quite a while. I believe I started even before Local First software was a thing. However, it turns out that if you're passionate about privacy and performance, you end up self-discovering many of the Local First principles. I found out later that Local First was a thing and that what I had been doing lined up with it's principles very nicely. See "Related Reading" below for more info on what Local First is if you're not familiar.
The Sqrte Tasks front end can operate independent of a backend when running on a single device. Your data is stored locally in the browser and can be exported at will. I decided to open source the parts required to run standalone like this. The "premium" parts required for syncing across multiple devices (with e2e encryption) remain closed at this point but many of these parts reside in the public repo (under a different license) so that people can still see how it all works.

I hope you like this take on what todo lists can be. I would love to hear any feedback you may have. Have fun!
