Privacy Policy

Last updated: 1 November 2026

    The short version: your camera video never leaves your device. The Work Runner works out
    your steps inside your own browser and only ever sends numbers (like distance and steps) to our server.
    We don't ask for your name, email or password.
  

Your camera

The Work Runner uses your camera to detect your running motion. The video is processed entirely in your browser by a pose-detection model running on your device. No video, photos or images of you are uploaded, stored or seen by anyone. The pose model files are downloaded from a public content network (jsDelivr and Google's model storage), but your camera images are never sent to them.

What we store

Data	Why
Your username	Shown on leaderboards, groups and live rooms.
Your runs: distance, steps, active time, top speed, start time	To build your totals and the leaderboards.
Your country (from your network connection, set when you create your username)	For country leaderboards.
Groups you create or join, and invites	To run group leaderboards.
A hashed version of your recovery code and login tokens	So you can stay logged in and recover your account. We can't read the original codes.
A hashed version of your IP address, kept for at most 24 hours	To limit abuse, like mass sign-ups.

While you're in a live room, other runners in that room see your username, distance and speed for that session.

What stays in your browser

Your browser's local storage keeps your username, a login token and your recovery code, so you stay logged in. Clearing your browser data removes them. Use your recovery code to get your account back.

Bot protection

When you create a username we use Cloudflare Turnstile to check you're a person. Turnstile may process information about your browser and device for that check, under Cloudflare's privacy policy.

Hosting

The Work Runner runs on Cloudflare, which processes network requests (including IP addresses) to deliver the site.

Advertising

The Work Runner may show ads in the future. If we do, this policy will be updated before then to explain which ad provider is used and what cookies it sets.

What we don't do

We don't collect your real name, email address or phone number.
We don't record, upload or store camera video or images.
We don't sell your data.

Deleting your data

To delete your account and all your runs, contact us with your username and recovery code (so we know it's really you) at alfi.siby.work@gmail.com.

Children

The Work Runner is not directed at children under 13, and we don't knowingly collect data from them.

Changes

If we change this policy we'll update the date at the top of this page.
