Privacy Policy

1. Overview & Core Privacy Promise

At FIT Overlay, we take your personal data privacy seriously. Unlike cloud-rendering video platforms, FIT Overlay operates on a local-first, client-side rendering model. Your raw video files (.mp4, .mov) and telemetry files (.fit, .gpx) are processed directly inside your local browser using WebCodecs and WebAssembly. Your video footage is never uploaded to or stored on our servers.

2. Data We Collect & How We Use It

A. Account & Authentication Data

When you sign in or create an account, we collect your email address and an authenticated user identifier via our database provider (InstantDB) to manage your Pro subscription status.

B. Payment & Billing Data

Payments are processed securely via Stripe, Inc. We do not store or process your credit card numbers or banking details directly. Stripe handles and secures all transactional information in compliance with PCI-DSS standards.

C. Strava & Intervals.icu API Integration

If you connect your Strava or Intervals.icu account, we request read-only access to your activities to fetch telemetry streams (speed, power, cadence, heart rate, GPS coordinates). This telemetry data is streamed directly to your local browser session and is not shared with third parties. You can disconnect your integration at any time in the account dialog.

D. Analytics & Diagnostics

We use privacy-friendly analytics (Vercel Analytics & Google Tag Manager) to monitor website performance and conversion effectiveness.

3. Cookies & Consent Mode

We adhere to the European ePrivacy Directive and GDPR Consent Mode v2 standards. Essential cookies required for authentication and session persistence are loaded automatically.

4. Your Rights (GDPR / DSGVO)

Under European data protection laws, you have the right to request access to your stored personal data, rectify inaccuracies, request deletion of your account, or restrict data processing. Contact us at support@fitoverlay.com.
