Information Stored Locally

Eluna may store the following information only on your device:

• user-created mixes and the sounds included in them;
• individual sound volume levels and playback preferences;
• language and interface preferences;
• sleep timer, alarm, and reminder settings; and
• cached subscription entitlement used to keep Plus features available offline.

Poison Studio does not receive the names you give your mixes or the exact content of your locally saved settings.

Information Collected Automatically

Eluna uses Google Analytics for Firebase and AppMetrica. Depending on your device, operating system settings, and service configuration, these services may process:

• App activity: screens viewed, buttons or features used, selected sound or composition identifiers, timer actions, paywall interactions, purchase outcomes, app language, and general subscription status such as “free” or “plus”.
• App and device information: app version, device model, operating system version, screen characteristics, language, network information, and technical identifiers such as an app-instance ID, Firebase installation ID, AppMetrica device identifier, or Android Advertising ID when available.
• Approximate location: a country or general region inferred from a masked IP address. Eluna does not request Android precise or approximate location permission.
• Diagnostics: crash information, stack traces, application performance, battery state, loading time, and related technical information.
• Subscription information: product identifier, product name, price, currency, purchase or renewal event, and purchase result. Poison Studio does not receive your full payment card or bank account details.

How We Use Information

We use information described in this Policy to:

• provide audio playback, timers, alarms, subscriptions, and other App functionality;
• verify access to Eluna Plus features;
• deliver configuration values through Firebase Remote Config;
• understand which screens and features are useful;
• diagnose crashes, performance issues, and technical errors;
• improve the App, user experience, and subscription flow;
• protect the App, prevent abuse, and comply with legal obligations; and
• respond to support, privacy, and data deletion requests.

Eluna does not display third-party advertising in the version covered by this Policy. Analytics providers may process advertising or device identifiers for measurement and attribution where those identifiers are available under your Android settings.

Sharing and Sale of Information

We do not sell your personal information. Information may be transmitted to the service providers listed above so they can provide analytics, diagnostics, configuration, and subscription services. We may also disclose information when required by law, to protect users or our legal rights, or as part of a merger, acquisition, or transfer of business assets, subject to appropriate confidentiality protections.

Data Retention

• Local App data remains on your device until you clear App storage or uninstall Eluna.
• Analytics and diagnostic information is retained according to our configured retention settings and the applicable policies of Google and AppMetrica.
• Support communications and privacy requests may be retained as reasonably necessary to resolve the request, maintain records, and comply with legal obligations.
• Aggregated or irreversibly de-identified information may be retained because it can no longer reasonably be associated with a user or device.

Data Security

We use reasonable technical and organizational safeguards intended to protect information. Information transmitted to Google services and AppMetrica is encrypted in transit. However, no electronic transmission or storage method is completely secure, and we cannot guarantee absolute security.

International Data Transfers

Our service providers may process information in countries other than the country where you live. Where required, we and our providers use recognized legal safeguards for international data transfers.

Children’s Privacy

Eluna is not directed to children under 13, or the minimum age required by applicable law in their country. We do not knowingly collect personal information from children. If you believe a child has provided information through the App, contact us so we can investigate and take appropriate action.
