I've been working on an application that uses nostr at its core called Cypher Log. It's not another social media site but rather a re-envisioned way to help manage all the complexities and tasks associated with running a home and storing information about your life. The goal of the site is to help track the more innocuous things that always get forgotten or lost. It stores info of when you bought furniture/applianaces/things and the documents associated with them, car maintenance and information, companies and services you use but put the contact details on sticky note you can't find, pet information and vet visit info, tracking warranties on products you bought, and planning/tracking small home DIY projects. I'm looking for feedback if anyone is interested in trying it out.
https://www.cypherlog.io/Everything is open source and its encouraged to run your own relay and blossom server to host the data for privacy reasons but if you choose to host the data on public relays everything is NIP44 encrypted so no one can read your intimate details. Pdf/image uploads require a blossom server and do not guarantee privacy unless the server is personal. Access all your information on any device through a browser or a PWA that works pretty well (atleast on android, I dont have an iphone). I think it may even be possible to connect an open claw agent via a NIP26 delegatee key that can manage and add new data to the site without having to do it yourself. Which is batshit crazy and awesome and an avenue i may pursue.
