Privacy Policy

Last updated: February 2026

Overview

WalkSync is a personal fitness app that connects to WalkingPad treadmills via Bluetooth and optionally syncs walking sessions to Strava. Your privacy is important, and this policy explains what data we collect and how it's used.

Data We Collect

Walking Session Data

When you use WalkSync, the app collects:

  • Duration of your walking sessions
  • Distance traveled
  • Walking speed
  • Session start and end times

This data is stored locally on your device and is not transmitted to any server unless you choose to sync to Strava.

Bluetooth Data

WalkSync connects to your WalkingPad treadmill via Bluetooth Low Energy (BLE) to read real-time walking data. No Bluetooth data is stored or transmitted beyond what's needed to display your current session.

Strava Integration

If you choose to connect your Strava account:

  • We store OAuth tokens securely in your device's Keychain
  • Walking sessions are uploaded to Strava only when you tap "Sync to Strava"
  • We request only the minimum permission needed: activity:write

Data Storage

  • Session history: Stored locally on your device
  • Strava credentials: Stored in iOS Keychain (encrypted)
  • No cloud storage: We do not operate any servers or cloud services

Third-Party Services

WalkSync integrates with Strava. When you sync activities, your data is subject to Strava's Privacy Policy.

Data Sharing

We do not sell, rent, or share your personal data with anyone. Your walking data stays on your device unless you explicitly sync it to Strava.

Your Rights

You can:

  • Delete the app to remove all local data
  • Disconnect Strava at any time in Settings
  • Delete individual sessions from your history
