About Cache Flow
Design Philosophy
Cache Flow is a single HTML file with zero dependencies. No build system, no frameworks, no servers, no accounts, no tracking. Open it in any browser, on any OS.
Your financial data is encrypted with AES-256-GCM and stored in your browser's local storage. It never leaves your device. Back up by exporting JSON; migrate by copying the HTML file and your export.
Simple. Private. Durable.
Support Development
Cache Flow is free and open source. If you find it useful, please consider supporting its development.
