WalkBrisk is a personalized interval walking coach. This policy explains what data we collect, how we use it, and the choices you have.

When you use WalkBrisk, we may collect:

• Account information: your email address and first name, used to identify your account and personalize greetings.
• Location and GPS route data: during outdoor walks, we use your device's GPS to track distance, pace, route, and elevation. This data is stored only if you grant location permission, and only for walks you actively start.
• Motion and step data: if you grant motion permission, we use your device's accelerometer to detect steps for more accurate activity tracking.
• Workout history: workout dates, times, duration, intervals, steps, distance, calories, pace, and elevation for walks you complete.
• Physical profile: age, sex, height, and weight that you provide to improve calorie and step-detection accuracy.
• Goals and activity level: your selected fitness goals and self-reported activity level, used to personalize your training plan.
• Settings preferences: voice, cue, color, and unit preferences.

• To generate and personalize your 8-week walking program.
• To track and display your workout history, progress, and achievements.
• To provide voice coaching and interval cues during walks.
• To calculate calorie and pace estimates based on your physical profile.
• To improve the app's accuracy and user experience.

Your data is stored securely and is associated with your account. Each user's data is isolated — other users cannot access your workouts, profile, routes, or settings. GPS route data and motion data are only collected during workouts you actively start.

We do not sell your personal data. We do not share your precise GPS routes, physical profile, or workout history with third parties. Anonymous, aggregated usage statistics may be used to improve the app.

Your workout history and profile remain on your account until you delete them. You can delete your account and all associated data at any time from Settings → Delete Account. This permanently removes your profile, workout history, GPS routes, interval data, and settings.

Location and motion access are optional. You can use WalkBrisk's interval coaching without granting these permissions. If you decline, distance, route, elevation, and automatic step counting will show as "Not tracked." You can change these permissions at any time in your device or browser settings.

WalkBrisk is not intended for children under 13. We do not knowingly collect data from children under 13.

We may update this policy from time to time. We will notify you of significant changes within the app.

If you have questions about this policy or your data, contact us through the app's support channel.
