Privacy Policy
Metamorph (the “Operator”, “we”, “us”) respects your privacy. This policy explains what data the Walking Speed App (“the App”) accesses and how it is used.
Data We Access
- Health data you allow via Apple HealthKit: walking speed and step counts. These are used only to compute in‑app summaries and analysis. The App does not write data to HealthKit.
- Diagnostic information (e.g., crash logs) may be collected by Apple or the operating system to improve reliability. The App itself does not collect personally identifying information.
How We Use Data
- Provide core features like summaries, trends, and PDF export
- Improve quality and troubleshoot issues (e.g., via system diagnostics)
Sharing and Third Parties
We do not sell or share your health data with third parties. If the App integrates optional services in the future (e.g., analytics), those will be documented here and governed by the respective provider’s policy.
Retention
Health data is read from HealthKit on‑device and used in real time to compute views. We do not store your health data on our servers.
Security
Health data access requires your explicit HealthKit permission. On‑device protections apply as provided by iOS and Apple Health.
Children’s Privacy
If you are under the age required by your local law to consent to data processing, use the App only with a parent or guardian’s permission.
Your Rights
You can manage HealthKit permissions in the iOS Settings or the Apple Health app. For questions or requests regarding your information, contact us at the email below.
Changes to This Policy
We may update this policy as needed. Significant changes will be reflected on this page.
