Sluip — Privacy-First Cycling PWA
Personal Project
About
Sluip is a privacy-first cycling PWA built with vanilla JS, Leaflet maps, and IndexedDB storage. It targets commuters in the Netherlands, EU, and US who want a Strava alternative without surveillance. The app features live route mapping, wind data overlays, commute tagging, GPX/CSV export, light/dark mode, route image sharing, and full offline support — all without requiring an account, server, or any form of tracking.
The story behind the name
In the Netherlands, every cyclist knows a sluiproute — a back road, a shortcut, the quiet path through the neighborhood that skips the busy intersection. The word comes from sluipen (to move quietly) and route: the way a local rides when they know the roads well enough to find a better one. Sluip is named after this idea. It's a cycling app for the ride you actually take every day — your commute, your familiar route — without being tracked, profiled, or asked to create an account. Your routes stay on your device, your data stays yours, and the name stays Dutch: practical, daily, private.
How to say it
Start with "sl," then say "oy" as in boy but with rounded lips, and finish with a "p."
