Privacy Policy

This Privacy Policy explains what data is collected, how it's processed, and what rights you have when you use the Stridavo mobile app, built by Zyphorion, and this website (stridavo.com).

1. Data collected in the Stridavo app

To power run, walk, and ride tracking, Stridavo processes the following data. None of it is sent to a server — it's kept only in the app's local storage on your own device:

• Location data: when you start an activity, your device's GPS location is used to calculate your route, distance and pace/speed.
• Motion/step data: the step-counter sensor may be used to support run and walk statistics (not used for cycling).
• Heart rate data: if you've paired a Bluetooth heart rate band or smartwatch, your live heart rate and average/max heart rate during a workout are recorded.
• Profile information: optional details like name, age, gender, height and weight, used for personalized pace and calorie estimates.
• Activity history: distance, time, pace/speed, route, elevation, splits, and heart rate data for each completed activity is saved on your device.

2. Device permissions

Stridavo may request the following operating-system permissions to deliver its core features:

• Location: to calculate your route and distance during an activity.
• Physical activity / motion sensors: for step data.
• Bluetooth: to pair a heart rate band or smartwatch and read live heart rate.
• Notifications: to show pause/resume/stop controls in the notification area during an activity.
• Storage / photos: to save your share card or exported GPX file to your device.

None of these permissions are used to collect data silently in the background — each is only active when you're using the related feature, and you can revoke any of them at any time in your device settings.

3. Heart rate devices and Health Connect

When you pair a Bluetooth heart rate band or smartwatch, heart rate data travels directly device-to-device — it never passes through Stridavo's or Zyphorion's servers.

On Android, you can use Health Connect to import an activity your smartwatch's own app already recorded (distance, duration, heart rate, steps) into Stridavo. This import only happens with your consent, through Android's own Health Connect permission screen, and the imported data is likewise stored locally on your device.

4. How data is stored

Stridavo doesn't require creating an account or signing in. Your profile and activity history are stored in a local database on your device and are not automatically uploaded to our servers or any cloud service. Deleting the app also deletes this data from your device.

5. The iOS notify-list website (stridavo.com)

When you submit the iOS notify form on this website with your email address, that information is stored so we can notify you when Stridavo launches on iOS.

Your email is used only for that notification and directly related updates — it's never sold to third parties or used for advertising. You can request deletion of your entry at any time by emailing stridavo@outlook.com.

6. Third-party services

The Stridavo app does not include any advertising network or third-party analytics tracking. The contact form may use a form-processing service (e.g. Formspree) to collect submissions; that service processes the information you submit only in order to deliver it to us.

7. Children's privacy

Stridavo does not knowingly collect data from children under 13. If we become aware that this has happened, we will delete the relevant data.

8. Your rights

You can edit or delete your profile and activity data at any time directly within the app. For access, correction or deletion requests related to your notify-list entry, contact us using the details below.

9. Changes to this policy

We may update this policy from time to time. Material changes will be posted on this page and the “last updated” date above will be revised.
