Nesta Life ("we", "us", or "our") is committed to protecting your privacy. This Privacy Policy describes the types of information we collect when you use the Nesta Life mobile application ("App"), how we use and protect that information, and your rights and choices regarding your data.
By using the App, you agree to the collection and use of information as described in this policy. If you do not agree, please do not use the App.
Information you provide directly includes:
Health data via Apple HealthKit (only with your explicit permission):
Information collected automatically (only where required for App functionality):
Nesta Life routes your health data and user-provided inputs to an AI coaching agent powered by Google Cloud Vertex AI. The AI processes this data to generate personalised challenges, biohacks, directives, and coaching recommendations. All data sent to the AI agent is processed securely and is not used to train third-party AI models.
Important: All AI-generated content — including coaching conversations, challenges, biohacks, and directives — is automatically and permanently deleted every day at 12:00 AM. This data is not retained in any form after deletion.
A minimal set of account data is stored in Google Cloud Firestore solely to enable core app functionality:
No personal health data, workout logs, nutrition entries, AI conversations, or HealthKit data is stored in Firestore. Accounts inactive for more than 30 days are automatically and permanently deleted from our database.
We do not use your data for advertising, and we do not sell your personal data or health information to any third party.
Nesta Life integrates with Apple HealthKit to retrieve health and fitness metrics. We strictly adhere to Apple's HealthKit guidelines:
You may revoke HealthKit access at any time via Settings > Privacy & Security > Health on your iOS device.
Google Cloud & Vertex AI: Your health, workout, and wellbeing inputs are securely transmitted to Google Cloud Vertex AI to power the Nesta AI coaching agent. Data is processed under a data processing agreement and is not retained for AI training purposes.
RevenueCat: Handles subscription management and payment processing. For details, see their Privacy Policy at revenuecat.com.
Apple Push Notification Service (APNs): Used to deliver Nesta messages and reminders to your device. Apple's standard privacy terms apply.
Local app data is stored on your device using iOS UserDefaults and Keychain. Data transmitted to cloud services uses TLS/HTTPS encryption. We apply industry-standard security practices for all cloud data access.
No method of electronic storage or transmission is completely secure. While we strive to protect your data, we cannot guarantee absolute security.
To request deletion of any server-side data associated with your account, please contact us at [email protected].
The App is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe we have inadvertently collected such information, please contact us immediately at [email protected] and we will take steps to delete it as soon as possible.
Depending on your location, you may have the right to access, correct, delete, or export your personal data, or to withdraw consent for data processing at any time. To exercise any of these rights, please contact us at [email protected]. We will respond within 30 days.
You can disable Nesta Life push notifications at any time by going to Settings > Notifications > Nesta Life on your iOS device. Disabling notifications will not affect the core functionality of the App.
We may update this Privacy Policy from time to time. We will notify you of significant changes through an in-app notification at least 30 days before changes take effect, where practicable. Continued use of the App after the updated policy becomes effective constitutes your acceptance of the revised policy.
