Privacy Policy

Last updated: July 2026

RC Replay — the website at rc-replay.dev and the RC Replay mobile app — lets you watch replays and live timing of radio-control (RC) car races. This policy explains what data we handle.

No account, no personal data

RC Replay has no sign-up or login, and keeps no profile of you. It reads publicly available race timing directly from myrcm.ch, everlaps.com and liverc.com. The website and the app send a small number of anonymous usage events, described below.

Data sources

Race schedules, results, and live timing are public data published by myRCM (myrcm.ch), Everlaps (everlaps.com) and LiveRC (liverc.com). RC Replay is an independent viewer and is not affiliated with, or endorsed by, myRCM, Everlaps or LiveRC.

Analytics

The rc-replay.dev website uses aggregate analytics (Vercel Analytics and Speed Insights) to understand traffic and performance. The website and the mobile app also send a short, fixed list of anonymous product events to PostHog (EU region) — which providers are watched live, that a replay was opened, that a driver was followed, that a notification was tapped, and when a track map or a provider request failed. These tell us which features are worth keeping and where the app is broken.

Both also record which pages or screens are opened, and the app records when it is opened and closed, so we can see which parts are used at all. Screens are recorded as their route shape (for example “/event/[id]/[section]/[k]”), not as a list of the particular races you looked at.

What they never contain: your name, a driver’s name, your follow list, or any account or device identifier we could tie back to you. There is no session recording, no automatic capture of taps or clicks, and no user profiles — only counts. On the website you can opt out entirely by opening any page with ?noanalytics=1, which switches analytics off for that browser permanently.

Notifications

On both the website and the mobile app you can optionally “follow” a driver to get a push notification when they are up next. This is off until you opt in on your first follow. If you opt in, we store your device’s push subscription — a browser push subscription on the web, or an Expo push token on mobile — solely to deliver those notifications. The list of drivers you follow is kept on your own device. You can stop any time by unfollowing or revoking notification permission.

Data sharing & retention

We do not sell or share your data, and we keep no personal profiles. Push subscriptions and tokens (if you opted in) are removed when they expire or when you unfollow.

Children

RC Replay is a general-audience app and does not knowingly collect data from children.
