Privacy Policy

Last updated: May 11, 2026
Effective date: May 11, 2026

This Privacy Policy applies to the Longevity Axis mobile apps operated by [LEGAL NAME OR COMPANY NAME], including Longevity Axis: Sleep, Longevity Axis: Hydration, and Longevity Axis: Movement.

The Longevity Axis apps are designed as local-first wellness tools. Your sleep logs, hydration logs, movement logs, habits, goals, and wellness insights are stored on your device and are not sent to our servers.

Educational and Wellness Use Only

The Longevity Axis apps provide educational wellness insights only. They are not medical devices, do not provide medical advice, and are not intended to diagnose, treat, cure, or prevent any disease or medical condition. Always consult a qualified clinician before making health, medical, hydration, exercise, or lifestyle decisions.

The apps may store information locally on your device so they can show progress, calculate trends, and remember your preferences.

This information is stored through the device’s local app storage. We do not operate a cloud account system for these apps, and we do not receive or store copies of your wellness logs on our servers.

Cross-App Local Integration

Some Longevity Axis apps may read scores from other Longevity Axis apps installed on the same device. For example, Hydration may read a Sleep score, and Movement may read Sleep and Hydration scores. This is local device storage access only. These scores are not transmitted to our servers.

Information We Do Not Collect

The apps do not require an account.
The apps do not collect your email address through the apps.
The apps do not collect precise or approximate location.
The apps do not access your camera, microphone, contacts, photos, or files.
The apps do not connect to Apple Health, Google Fit, or wearable sensor APIs in the current builds.
The apps do not collect biometric identifiers.
The apps do not use advertising SDKs or third-party analytics trackers.
The apps do not sell your personal information.
The apps do not share your wellness logs with advertisers.

Notifications

The apps may offer local reminders, such as sleep, hydration, or movement reminders. If notification permission is requested and you grant it, reminders are scheduled locally on your device. You can turn notifications off through the app settings where available or through your device notification settings.

Subscriptions and Purchases

If you purchase an optional Pro subscription, payment is processed by Apple through the App Store or by Google through Google Play. We do not receive, store, or process your payment card information.

The apps use RevenueCat to help verify subscription entitlement status and restore purchases. RevenueCat may receive purchase-related information, app identifiers, device information, and an anonymous app user identifier needed to provide subscription functionality. Your sleep logs, hydration logs, movement logs, habits, goals, and morning check-ins are not sent to RevenueCat. You can review RevenueCat’s privacy policy at https://www.revenuecat.com/privacy.

How Information Is Used

To show your progress and history.
To calculate streaks, goals, scores, and wellness trends.
To generate educational insights based on your local entries.
To remember your preferences.
To enable local reminders.
To confirm whether Pro features should be unlocked.
To provide optional cross-app insights when multiple Longevity Axis apps are installed.

The analysis and insight calculations run locally in the apps.

Data Sharing

We do not share your locally stored sleep logs, hydration logs, movement logs, habit logs, morning check-ins, or custom habits with third parties. Subscription-related information may be handled by Apple, Google, and RevenueCat so purchases can be processed, verified, and restored.

Data Retention and Deletion

Your wellness data remains on your device unless you delete it. You can delete local app data by using the “Clear All Data” option in each app’s settings, uninstalling the app, or clearing the app’s storage through your device settings where supported.

Because we do not receive your local wellness logs, we cannot delete that local device data for you remotely.

Security

We use a local-first design to reduce the amount of information transmitted outside your device. No method of electronic storage is perfectly secure, so you should protect your device with a passcode, biometric unlock, and operating system security updates.

Children’s Privacy

The apps are not directed to children under 13. We do not knowingly collect personal information from children under 13. If you believe a child under 13 has used a Longevity Axis app and you need help managing local app data, please contact us.

International Users

If you use the apps outside the United States, you understand that subscription providers and app stores may process purchase-related information in the countries where they or their service providers operate.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time. If we make changes, we will update the “Last updated” date above. Continued use of the apps after a policy update means you accept the updated policy.
