Free, private, open-source retirement planning — no login, no server, no data leaving your browser.
We believe everyone should be able to plan their retirement without handing their financial life to a third party. Everything we build starts from that idea: your data stays on your device, the code is open for anyone to inspect, and the core planning tools are free.
