π 100% In-Browser Execution β’ Zero Telemetry Storage
Privacy Policy
Effective Date: November 2026
1. Client-Side Telemetry & Activity Privacy
RunningOverlay.com is designed from the ground up to protect your personal privacy. When you
upload or configure a GPS activity file (.GPX):
- All GPX parsing, telemetry calculation, canvas graphics rendering, and video encoding
(WebAssembly / FFmpeg) execute 100% locally inside your web browser on your
device.
- Your GPS coordinates, routes, elevation, heart rate, cadence, power, timestamps, and video
exports are never sent to, processed on, or stored by any server.
- When you close or refresh your browser tab, all session memory and temporary activity data
are completely cleared by your browser.
2. Strava API Integration & Data Compliance
RunningOverlay.com integrates with the Strava API in strict accordance with the Strava
API Agreement, Strava API Policy, and Strava API Brand
Guidelines:
- Minimal Necessary Scope: We request only read-only access
(
activity:read_all) to allow you to select and import your own running or
cycling activities and their associated telemetry streams. - Zero Telemetry Stored on Servers: All GPX streams, GPS coordinates,
elevation, speed, heart rate, cadence, and power data retrieved from Strava are loaded
directly into your client browser and processed entirely in memory on your local machine. No
telemetry data is ever transmitted to, stored on, or retained by any server or external
database.
- No Third-Party Sharing, Resale, or Profiling: We never share, sell,
license, disclose, or distribute your Strava athlete information or activity data to
advertisers, data brokers, or third parties.
- No AI or Machine Learning Model Training: Your Strava activity data is
strictly prohibited from being used to train, evaluate, or fine-tune artificial intelligence
or machine learning models.
- Revocation & Instant Data Deletion: You retain complete control over
your data. You may revoke access and delete all stored tokens and cached activities at any
time by clicking the "Disconnect" button in the Strava modal, or by revoking access directly
via your Strava Account Settings (under "My Apps"). Disconnecting immediately purges all
tokens and Strava-related data from your browser's local storage.
3. Cookies, Local Storage & Tracking
RunningOverlay.com does not use tracking cookies, advertising beacons, digital fingerprinting, or
third-party behavioral analytics. Browser local storage is used solely for functional,
user-requested
preferences: remembering your KM/MI unit selection and retaining your Strava authentication so
you do not have to reconnect on every visit. You can clear this anytime via your browser
settings or by clicking "Disconnect" in the Strava dialog.
4. Cloudflare Pages Hosting & Server Logs
This website is hosted statically via Cloudflare Pages. As with standard web hosting protocols,
Cloudflare processes transient technical access logs (such as requesting IP address and
User-Agent) solely for internet routing, security, and DDoS mitigation in compliance with the
Cloudflare Privacy Policy.
5. External Third-Party Links
The website contains optional external links (such as "Buy Me a Coffee" for voluntary creator
support). Clicking external links directs you to third-party domains with their own respective
privacy policies and terms.
