Privacy Policy

Effective Date: February 24, 2026

Last Updated: February 24, 2026

This Privacy Policy explains how SereneArc LLC ("SereneArc," "we," "us," or "our"), operator of the Zzzon mobile application, collects, uses, discloses, and protects your information. We are committed to protecting your privacy, especially because Zzzon is a sleep and wellness app where you may share sensitive information about your emotional and mental state.

By using Zzzon, you agree to the collection and use of information as described here.

1. Information We Collect

1.1 Information You Provide

When you create an account and use Zzzon, we may collect:

  • Account Information: Name (optional), email address, or Apple ID

  • Username: Your chosen display name

  • ZzzLog Entries: Journal content including emotion states, reflection text, and timestamps — stored privately, linked to your account

  • Challenge Responses: Your answers to challenge questions and ratings (thumbs up/down)

  • Feedback: Written feedback you submit about challenges or the app

  • Survey Responses: Optional onboarding survey answers about your sleep situation

1.2 Information Collected Automatically

When you use the App, we automatically collect:

  • Usage Data: Challenges started, completed, and exited; time spent in app; categories accessed

  • Device Information: Device type, OS version, and app version

  • Analytics Events: Key in-app actions (challenge starts, completions, exits, journal entries, purchases)

  • Crash Reports: Error logs to help us fix bugs

We do not collect sleep tracking data, location data, microphone audio, or contacts.

We do not use third-party advertising SDKs or cross-app tracking technologies.

1.3 Payment Information

All purchases are processed by Apple through the App Store. SereneArc LLC does not collect or store payment card details. We receive limited transaction data (subscription tier and status) from RevenueCat and Apple to manage your premium access.

1.4 Sensitive Information

Zzzon may collect information that could be considered sensitive, including emotional states you record in ZzzLogs. We treat this information with particular care. Zzzon does not process emotional or journal data for diagnostic, profiling, or health assessment purposes. ZzzLog content is not used for analytics, profiling, or product decision-making. Other non-content usage data (such as challenge sessions, interactions, and feedback) may be analyzed to improve the Service.

2. How We Use Your Information

We use collected information to:

  • Provide, operate, and maintain the Zzzon Service

  • Process and manage your account and subscriptions

  • Personalize your in-app experience

  • Track progress and award points through the gamification system

  • Analyze user activity (such as challenge sessions, interactions, and feedback) at both aggregated and individual levels to understand product usage, troubleshoot issues, and improve the Service

  • Send important service-related communications

  • Respond to support requests and feedback

  • Detect and prevent fraud, abuse, or Terms violations

  • Comply with legal obligations

We may review user activity through internal tools and dashboards in order to understand how the Service is used, diagnose issues, and improve user experience. Access to this information is restricted and used only for internal product, support, and operational purposes.

We do not use your ZzzLog content or challenge responses for advertising. We do not sell your personal data to third parties.

3. Legal Basis for Processing (GDPR)

When you delete your account, we will delete or anonymize your personal data within 30 days, except where we are required by law to retain it. Anonymized, aggregated analytics data that cannot be linked back to you may be retained for service improvement purposes.

For EEA/UK users, we ensure compliance with applicable data protection laws, including through standard contractual clauses or equivalent safeguards where required.

10. Analytics and Crash Reporting

We use analytics tools (such as Firebase Analytics) and internal systems to understand how users interact with Zzzon, including challenge usage, session outcomes, and feedback.

This analysis may include both aggregated and user-level activity data for the purpose of improving product design, debugging issues, and enhancing user experience.

Firebase Crashlytics helps us identify and fix app crashes. Google's use of Firebase data is governed by Google's Privacy Policy (firebase.google.com/support/privacy).
