Fitport Privacy Policy

Effective Date: April 2026 Last Updated: April 2026

Overview

Fitport is a Chrome Extension that exports fitness data from Peloton and MyFitnessPal. All data processing happens entirely within your browser. No fitness data is ever transmitted to external servers.

Data Collection

What Fitport Accesses

Peloton workout data: Retrieved via the Peloton API using your existing browser session. Includes workout history, performance metrics, heart rate, and instructor information.
MyFitnessPal nutrition data: Extracted from your food diary pages using your existing browser session. Includes daily calorie totals, macronutrient breakdowns, and meal entries.

What Fitport Does NOT Collect

No personally identifiable information (PII) is collected or stored
No fitness data is transmitted to any server
No analytics, telemetry, or tracking scripts are included
No third-party services receive your data
No browsing history outside of supported platforms is accessed

Data Processing

All data processing occurs 100% client-side within the Chrome extension:

Data is read from the platform (Peloton API or MFP page DOM)
Data is normalized into a unified format within the extension
Data is formatted (Markdown-KV, JSON, YAML, or CSV) in-browser
The formatted output is provided to you via clipboard copy or file download

At no point does your fitness data leave your browser.

Data Storage

Fitport uses minimal Chrome extension storage:

chrome.storage.sync: Stores only your Pro license activation record — the license key, an opaque per-install instance ID, the current status flag, and an expiration timestamp returned by the licensing provider. Contains no fitness data.
chrome.storage.session: Temporarily stores export state during an active export (cleared when the export completes or the browser session ends)

No fitness data is persisted in any storage. Exported data exists only in memory during the export process.

Third-Party Services

Fitport itself runs no servers. The only third-party service the extension contacts beyond the source platforms is Lemon Squeezy, which handles payments and license-key validation for the optional Pro tier:

When you upgrade, you complete checkout on Lemon Squeezy's hosted checkout page. Lemon Squeezy is the Merchant of Record and processes the payment under its own privacy policy.
When you activate or validate your license key inside Fitport, the extension sends only the license key string and an opaque per-install instance ID to Lemon Squeezy's License API.
No fitness data is ever sent to Lemon Squeezy or to any other third party. Lemon Squeezy never sees your workouts, nutrition entries, or any data extracted from Peloton or MyFitnessPal.
If you choose to remain on the free tier, the extension makes no calls to Lemon Squeezy at all.

Chrome Extension Permissions

Fitport requests the following permissions, each for a specific purpose:

Permission	Purpose
`sidePanel`	Renders the Fitport UI as a Chrome side panel
`activeTab`	Detects which platform (Peloton/MFP) is open in the active tab
`storage`	Stores the Pro license activation record (license key, instance ID, status, expiration)
`cookies`	Checks Peloton login status via session cookie
`alarms`	Keeps the service worker alive during long exports
`scripting`	Injects content scripts to extract MFP nutrition data from page DOM

Host Permissions

https://members.onepeloton.com/* — Peloton platform detection and cookie access
https://www.myfitnesspal.com/* — MFP platform detection and content script injection
https://api.onepeloton.com/* — Peloton API requests for workout data

GDPR and Data Portability

Fitport is a data portability tool aligned with GDPR Article 20 (Right to Data Portability). It enables users to export their own fitness data in structured, commonly used, and machine-readable formats. Since all processing is client-side, no data controller obligations apply to the extension itself.
