Hey everyone — PrestaBook is a loan tracker I built because I was tired of tracking loans with notes apps and spreadsheets. A few things that make it different: - Your data stays yours — local-first, encrypted on your device. If you sync, it goes to your own Google Drive as an encrypted backup. - No backend — PDF receipts generated in-browser, everything works offline. - No signup — just open and start tracking. I made it for tracking loans to friends, family, and clients without the awkwardness of "hey, remember you owe me." It's a PWA so it works on any device, and there's a mobile app coming. Would love your feedback — especially on whether the local-first approach makes sense for this use case.
