Last Updated: March 21st, 2025

This Privacy Policy explains how information about you is collected, used, and disclosed by YMMV LLC ("we," "us," or "our") when you use our mobile application "Null Fasting" (the "App") and related services (collectively, the "Services").

By using the Services, you agree to the collection, use, and disclosure of your information in accordance with this Privacy Policy. If you do not agree, please discontinue use of our Services.

We may change this Privacy Policy from time to time. If we make changes, we will notify you by revising the date at the top of the policy and, in some cases, provide you with additional notice (e.g., an in-app alert or email). We encourage you to review this Policy whenever you access the Services to stay informed about our information practices and the ways you can help protect your privacy.

  • Fasting Data: When you use the App, we collect information about the fasts you create, track, and complete, including fast types, durations, start and end times, completion status, and any notes you add.
  • Health Metrics: If you choose to enter health information such as weight or water intake, we collect this data to help you track your progress.

  • Usage Data: We may automatically collect information regarding your use of the Services, such as features accessed, fasting patterns, app performance metrics, error logs, and interaction data.

2. USE OF INFORMATION

We use the information we collect to:

  • Provide fasting tracking functionality and maintain accurate records of your progress.
  • Generate statistics, streaks, and insights about your fasting patterns.
  • Track awards and achievements related to your fasting journey.
  • Operate, maintain, and improve the Services and personalize the user experience.
  • Respond to your inquiries, provide support, and send important updates about the App.
  • Analyze app performance, monitor usage trends, and improve our understanding of user preferences.
  • Send you technical notices, updates, security alerts, and administrative messages.
  • Detect, investigate, and prevent fraudulent or illegal activities, and protect the rights, property, or safety of our users or others.

3. SHARING OF INFORMATION

We may share your information in the following ways:

  • Service Providers: We may share information with third-party vendors, consultants, and other service providers who need access to such information to carry out work on our behalf (e.g., hosting, analytics, customer support).
  • HealthKit Integration: With your permission, we may share certain health-related data with Apple HealthKit. This sharing is exclusively for providing the functionality you request, and we do not use data from HealthKit for advertising or data mining. Our use of HealthKit data complies with Apple's guidelines and your sharing preferences.
  • Compliance with Legal Obligations: We may disclose your information to comply with a legal or regulatory requirement, to respond to a subpoena or court order, or in connection with any legal process or governmental request.
  • Protection of Rights and Safety: We may disclose information when we believe doing so is necessary to protect the rights, property, or safety of YMMV LLC, our users, employees, or others.
  • Business Transfers: If we are involved in a merger, acquisition, financing, or sale of assets, your information may be transferred as part of that transaction.
  • With Your Consent: We may share information about you for any other purpose disclosed to you and with your consent.

4. LOCAL DATA STORAGE

Null Fasting primarily stores your fasting tracking data locally on your device using Core Data. This means your personal fasting information remains on your device and is not routinely transmitted to our servers. However, certain features of the App may require data transmission for functionality, such as analytics and error reporting.

5. SECURITY

We implement reasonable security measures to protect your information from unauthorized access, use, alteration, and disclosure. However, no method of transmission over the Internet or method of electronic storage is completely secure, and we cannot guarantee its absolute security.

6. CHILDREN'S PRIVACY

The App is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us at support@nullfasting.com so we can remove the information.

7. USER-GENERATED CONTENT

The fasts, notes, and other content you create within the App are considered user-generated content. While this information is primarily stored locally on your device, please be mindful when creating custom fast notes that may contain personal information.

8. YOUR CHOICES

App Data:
You can delete individual fasts or all app data through the App's settings. Local data can be removed by uninstalling the App.

Push Notifications:
You can manage or opt out of fast reminders, milestone notifications, and other notifications by adjusting the permissions in your device settings or within the App.

You can control which health data is shared with the App through your device's Health app settings. You can enable or disable the App's access to specific data types at any time.

9. INTERNATIONAL DATA TRANSFERS

We may process your personal information outside of your home country. Data protection laws vary among jurisdictions. If we transfer your information to another country, we will ensure the transfer is lawful and that adequate security measures are in place to protect your information.

10. DATA RETENTION

We retain personal data for as long as necessary to provide the Services, fulfill the transactions you have requested, or for other essential purposes such as complying with our legal obligations, resolving disputes, and enforcing our agreements. Your fasting tracking data remains on your device until you choose to delete it or uninstall the App.

To the fullest extent permitted by law, YMMV LLC and its affiliates, officers, employees, agents, partners, and licensors are not liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to lost profits, personal injury, or property damage related to or in connection with your use of the App and its content.
