Privacy

Last updated 27 August 2026

The short version: this website collects nothing. Playing LingoRun on your own server sends us nothing. Playing the invitation-only hosted game stores your practice — and only your practice — in a private world that exists for you alone.

This website

lingorun.com is a static page. It sets no cookies, runs no analytics, and loads every file — including its fonts — from this domain, so visiting it tells no one else anything. It is served by Cloudflare Pages, whose infrastructure handles the network request like any web host does; Cloudflare's own practices are described in the Cloudflare privacy policy.

Running your own server

LingoRun listens to your voice — that's how you steer — and grades what you say and what you draw. When you run the judge server yourself, on your own computer and your own network, all of that stays between your device and your server. There is no account, no analytics, and no third-party service: your recordings, your drawings, and your review history live on hardware you control, and we never see any of it.

Playing at play.lingorun.com (invitation only)

The hosted game exists so an invited guest can play without running anything. There is no registration: a personal invitation link, valid for 30 days, is the only way in. Opening it sets one cookie — the invitation itself, so you stay let in — and nothing else; there are no analytics or advertising trackers of any kind.

While you play, your voice is streamed to your world's judge server to be graded, exactly as it would be to a self-hosted one. What the game needs to remember — recordings of your attempts, your drawings, your review history, and any notes you capture — is stored in an isolated per-invitation world on Cloudflare's infrastructure, readable by no other guest. Text you capture as study material (not your voice) may be sent to Anthropic's API to generate your personalised sentences; Anthropic's handling is described in their privacy policy.

Your world lives as long as your invitation and is deleted afterwards; if you want it gone sooner, say so and it will be.
