Subsight is an offline-first subscription tracker for people who don't want to hand over their bank login just to see what they're paying for. No account. No bank linking. No cloud sync. Every subscription, renewal date, and cost — tracked entirely on your device, across 170+ currencies. Built solo by a self-taught 19-year-old developer using AI-assisted workflows. No team, no funding — just a belief that tracking spending shouldn't mean giving up financial privacy. Your data stays yours.
