Privacy Policy

Last updated: April 1, 2026

Abstia, LLC (“we,” “our,” or “us”) operates the Abstia mobile application (the “App”). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our App.

1. Information We Collect

Account Information

When you create an account, we collect:

  • Display name
  • Email address
  • Authentication credentials (password hash — we never store plaintext passwords)

If you sign in with Google or Apple, we receive your name and email from those providers. We do not receive or store your Google or Apple password.

Fasting Data

When you use the App, we collect data you provide:

  • Fast start and end times
  • Target durations and fasting schedules
  • Fast completion status (completed or cancelled)
  • Biofeedback entries: mood (great/struggling), hunger type (physical/mental), and energy level (high/low)
  • Optional notes you add to fasts

Preferences

  • Timer display mode (countdown or count-up)
  • Theme preference (system, light, or dark)
  • Notification settings and preferences
  • Timezone

Device Information

  • Push notification token (if you enable notifications)
  • Device platform (iOS or Android)

2. How We Use Your Information

We use the information we collect to:

  • Provide and maintain the App
  • Track and display your fasting history and progress
  • Generate personalized AI coaching tips based on your fasting patterns
  • Send notifications you have opted into (target reached, ending soon, starting reminders, coaching tips)
  • Sync your data across devices
  • Improve the App

3. Data Storage and Security

Your data is stored securely in the cloud with strict access controls. Your data is fully isolated — only you can access your own records, even at the database level.

The App also stores data locally on your device using SQLite for offline access. Local data syncs with our servers when connectivity is available.

All data transmission is encrypted using TLS/SSL. We use industry-standard security practices to protect your information.

4. Data Sharing

We do not sell, trade, rent, or otherwise share your personal information with third parties, except:

  • Service providers: We use Supabase for authentication and data storage, and PowerSync for offline data synchronization. These providers process data on our behalf under strict data protection agreements.
  • Legal requirements: We may disclose information if required by law or in response to valid legal processes.

5. Third-Party Authentication

If you choose to sign in with Google or Apple, those services provide us with your basic profile information (name and email). Their respective privacy policies govern how they handle your data:

6. Data Retention

We retain your data for as long as your account is active. If you delete your account, we will delete your personal data within 30 days. Anonymized, aggregated data may be retained for analytics purposes.

7. Your Rights

You have the right to:

  • Access the personal data we hold about you
  • Correct inaccurate data
  • Delete your account and associated data
  • Export your data in a portable format
  • Opt out of any or all notifications at any time through the App settings

To exercise these rights, contact us at privacy@abstia.com.

8. Children's Privacy

The App is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13. If we become aware that we have collected data from a child under 13, we will delete it promptly.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of material changes by posting the updated policy in the App or on our website. Your continued use of the App after changes are posted constitutes acceptance of the revised policy.
