Privacy Policy
Last updated: July 5, 2026
This Privacy Policy explains how Silver Mountain Technologies ("we", "us"), the maker of the RunGait iPhone app, handles information in connection with the app and the rungait.com website (together, the "Service"). We built the Service to be private by design: the gait analysis runs entirely on your device, and your video never leaves your phone unless you explicitly choose to share it.
1. Information we collect
- Account information. If you sign up with email, we store your email address and a securely hashed password (we never store your password in plain text). If you use Sign in with Apple, we store the identifier Apple provides and, if you share it, your email.
- Screening results and motion data. When you are signed in, the results of a screen (scores, findings, and your training plan) and the pose data (the anonymous body-landmark coordinates the app extracts from a clip) are saved to your account. This powers your history, lets you retest over time, and helps us improve the analysis. This data does not include your video.
- Video clips (only if you opt in). By default your clips are analyzed on your device and are not uploaded. If you turn on "Share clips to improve RunGait," the raw clips for that screen are uploaded to our secure storage and used to improve the analysis. You can turn this off at any time.
- Subscription information. Purchases are processed by Apple. We (and our subscription provider, RevenueCat) receive your subscription status and related identifiers so we can unlock paid features. We never receive your payment card details.
- Basic technical data. Standard information such as app version and device type, used to operate and debug the Service.
2. How we use information
- To provide the Service: run screens, save your history, and sync it across your devices.
- To operate subscriptions and unlock paid features.
- To improve the accuracy of our analysis and build better screening.
- To respond to support requests and keep the Service secure.
3. How information is shared
We do not sell your personal information. We share it only with service providers that help us run the Service, under agreements that limit their use of it:
- Apple — app distribution, Sign in with Apple, and subscription billing.
- RevenueCat — managing subscription status.
- Our hosting provider — running our servers and storing your account data.
- Our AI writing provider — the optional plain-language summary of your results is generated by sending only the anonymized numeric findings (no video, no name, no email). If you leave this feature off, nothing is sent.
4. Data retention and deletion
We keep your account data while your account is active. You can ask us to delete your account and associated data, including any uploaded clips, by emailing us at the address below. Some records may be retained where required by law.
5. Security
Data is encrypted in transit. Passwords are stored using a strong one-way hash. No method of storage or transmission is perfectly secure, but we take reasonable measures to protect your information.
6. Children
The Service is not directed to children under 13, and we do not knowingly collect their information.
7. Your choices and rights
You can keep clip sharing off, request access to or deletion of your data, and cancel your subscription at any time in your Apple account settings. Depending on where you live, you may have additional rights under laws such as the GDPR or CCPA; contact us to exercise them.
8. Not a medical service
RunGait is a training and screening tool, not a medical device. It does not diagnose, treat, or prevent any condition. Findings are training hypotheses, not medical advice.
9. Changes
We may update this policy. Material changes will be reflected by the "Last updated" date above.
