Rentenrechner - Simple retirement planning for everyone in Germany

Most German pension calculators look like they were built in 1998, only speak German, and require you to hand over sensitive financial data to a server. Rentenrechner is a high-performance, privacy-first tool designed to demystify the "Rentenlücke" (pension gap). I want to build a tool for retirement planning in Germany that can be used by people in Germany who don't speak German. It is meant to be simple to use but also allow heavy customization. Why it’s cool: Zero-Server Architecture: 100% client-side. Your salary and savings never leave your browser. Period. Trilingual Core: Instantly toggle between English, German, and Turkish. Thus, making the German system accessible to almost everyone. Simple but also detailed: Specifically designed to help people understand how their points (Entgeltpunkte) actually work. Vite-Fast: Built with React/Vite for a sub-second, snappy experience. No clunky forms, just instant results. Stop guessing your future. Map it out in 30 seconds.
