Privacy Policy

Duskreel ("the App", "we", "us", "our"), operated by Tranquil Mind Technology JSC, respects your privacy. This Privacy Policy explains what information we collect, how we use and share it, and the choices and rights you have. By using the App, you agree to this Policy.

Duskreel is a vertical short-drama streaming app: you swipe through series whose episodes run one to two minutes each. You do not need to create an account to use it — there is no sign-up, login, or profile, and we do not ask for your name, email address, phone number, or contacts.

1. Information we collect

The App collects the following automatically, through the third-party services listed in Section 3 and through our own streaming service:

• Device and advertising identifiers — including the Android Advertising ID (the App declares the com.google.android.gms.permission.AD_ID permission), the Firebase installation/app-instance identifier, and an anonymous purchase identifier generated by our billing provider. Used for advertising, analytics, install attribution, purchase validation, and fraud prevention.
• Approximate location — derived by our advertising, analytics, and attribution providers from your IP address (country/region level, not GPS). The App does not request device location permission and does not collect precise location.
• App activity — in-app events and interactions such as screens viewed, series and episodes opened, playback events, ads viewed and rewards earned, and paywall or purchase events. Used for analytics, install/activation attribution, and advertising measurement.
• Crash logs and diagnostics — crash reports, stack traces, device model, operating-system version, and app version, used to detect and fix stability issues.
• Purchase status — the fact, type, and status of any coin purchase or premium (VIP) subscription, processed through Google Play Billing and our subscription provider. Purchase events (the product bought, its price, and currency) are also recorded in our analytics and logged automatically by the Meta (Facebook) SDK to measure our advertising campaigns. We do not receive or store your payment card details.
• App and device integrity signals — our anti-tamper component checks whether the App has been modified, repackaged, or is running under a debugger, hooking framework, emulator, or rooted device, and reports these signals (together with device model, OS version, app version, and app signature) to its provider and to our analytics. This protects the licensed video content from unauthorized copying.
• Network connection state — the App checks whether a network connection is available (Android ACCESS_NETWORK_STATE permission) so it can pause playback and show an offline notice. This check stays on your device.
• Streaming service request data — when you browse the catalogue or play an episode, your device requests content from our streaming service at epsdrm.com and from the content delivery networks that host the video files. Those requests include your IP address, the requested series/episode identifier, the language code you selected, and standard technical request data (user agent, timestamps), which are processed to deliver the content and kept in server logs for security and troubleshooting.
• Install referrer — on first launch on Android, the App reads the Google Play Install Referrer once to detect whether you installed through a friend's invite link and, if so, to grant welcome coins. The invite code is processed on your device.
• App attestation — requests to our streaming service carry a Firebase App Check (Play Integrity) token, which lets us verify the request comes from the genuine App.

Stored only on your device (not collected by us): your continue-watching progress and watch history, the series you save, your coin balance and check-in streak, your language, subtitle language, playback speed, Night mode (sleep timer and screen dimming) and hidden-genre preferences, your ad-consent choices (stored in the standard IAB TCF format your device already keeps), and any ad-free window earned from a rewarded ad. These are held in local app storage and are removed when you clear the App's data or uninstall it. Search is performed on your device against the catalogue already downloaded — your search terms are not sent to us.

Reminders (optional). If you turn on the check-in reminder or the evening watch reminder, the App asks for notification permission and schedules local notifications on your device at the time you choose. Both are off until you opt in, and the schedule and reminder text never leave your device.

Permissions the App declares (Android): INTERNET, ACCESS_NETWORK_STATE, com.google.android.gms.permission.AD_ID, and POST_NOTIFICATIONS (only used for the optional reminders above). The App does not request camera, microphone, contacts, calendar, precise location, or file/photo access.

2. How we use information

• Provide, operate, and maintain the App and deliver the series and episodes you request.
• Remember your progress, saved series, coins, and preferences on your device.
• Serve and measure advertising, including personalized advertising where you have consented, and grant the rewards (coins, temporary ad-free time) earned from rewarded ads.
• Measure the effectiveness of our marketing campaigns (install and activation attribution).
• Analyze usage to understand and improve performance, content, and features.
• Detect, prevent, and investigate fraud, abuse, piracy, tampering, and security issues.
• Process and validate coin purchases and premium (VIP) subscriptions, and restore them for you.
• Comply with legal obligations.

3. Third-party services

The App uses the following third-party services, which may receive the data described above. Each is governed by its own privacy policy:

Ad consent (UMP). Where required (e.g. in the EEA/UK), the App presents a consent request managed through Google's User Messaging Platform before serving personalized ads. To change your choice later, clear the App's data in your device settings (the consent request is shown again the next time you open the App — note that this also resets progress and coins stored on your device), or contact us and we will help.

Reset or opt out of your advertising ID. You can reset or delete your Android Advertising ID, or opt out of ad personalization, in your device settings under Settings → Privacy → Ads (the path may vary by device). Doing so limits personalized advertising.

Sharing a series. If you use the share button, the App hands a link and a short text to the app you choose (messaging, social, email). We do not receive the recipient's details, and nothing is shared until you pick a destination.

4. How we share information

We do not sell your personal information for money. We share information with the third-party providers listed in Section 3 to operate the App, deliver content, and serve advertising; for legal reasons (to comply with law or to protect rights, property, and safety); and in connection with a business transfer (e.g. merger or acquisition).

U.S. state privacy notice. Because the App serves personalized advertising, the sharing of advertising and device identifiers with ad partners may be considered a "sale" or "sharing" (for targeted advertising) under certain U.S. state laws. You can opt out using the ad-consent controls and your device's advertising-ID settings described above.

5. Legal bases (EEA/UK — GDPR)

• Consent — personalized advertising and analytics where consent is required.
• Legitimate interests — providing and securing the service, preventing fraud and content piracy, and improving the App.
• Contract / legal obligation — processing and validating purchases and subscriptions, and meeting legal requirements.

6. Data retention

We keep information only as long as necessary for the purposes described or as required by law. Advertising, attribution, and analytics identifiers are retained according to each partner's retention periods; crash and diagnostic data are retained for a limited period to diagnose issues; streaming server logs are kept for a short period for security and troubleshooting. Data stored locally on your device remains until you clear the App's data or uninstall it.

7. Your rights

• GDPR (EEA/UK): access, correction, deletion, portability, objection, restriction, withdrawal of consent, and the right to complain to a data protection authority.
• CCPA/CPRA (California) and other U.S. states: the right to know, delete, and correct, to opt out of sale/sharing and targeted advertising, and to non-discrimination.
• Other regions (e.g. LGPD, PIPEDA): equivalent rights under applicable law.

To exercise your rights, contact us at contact@tranquilmind.co. Because the App has no accounts, please include your Android Advertising ID and relevant device details (and, for purchase-related requests, your Google Play order ID) so we can identify the associated data. You can also delete the data held on your device at any time by clearing the App's storage or uninstalling it.

Requesting deletion of your data. Email contact@tranquilmind.co with the subject "Data deletion request" and include your Android Advertising ID (Settings → Privacy → Ads). We will delete the data we hold that is linked to that identifier, ask our analytics and attribution providers to do the same, and confirm within 30 days. Data that we must keep for legal, tax, or fraud-prevention reasons (for example, purchase records) is retained only as long as required. Because the App has no accounts, there is no account to delete.

8. Children's privacy

The App is intended for users aged 16 and older and is not directed to children. Some series contain mature dramatic themes. The App has no chat, messaging, comments, profiles, or any other way for users to communicate with each other or upload content. We do not knowingly collect personal information from children under 16 (or the applicable minimum age of digital consent in your region). If you believe a child has provided us with information, contact us and we will delete it.

9. International data transfers

Your information may be processed in countries other than your own, including the United States. Where required, we and our providers rely on appropriate safeguards (such as Standard Contractual Clauses) for these transfers.

10. Data security

We use encryption in transit (HTTPS/TLS), app-integrity and anti-tampering protections, and other reasonable technical and organizational measures to protect information. However, no method of transmission or storage is 100% secure.

11. Third-party content

The series available in Duskreel are supplied through our streaming service and its content licensors and delivery networks. Advertising shown in the App is served by the ad partners listed in Section 3 and may link to third-party websites or stores. We do not control third-party websites or advertisers' privacy practices — please review their policies before providing them with information.

12. Changes to this Policy

We may update this Policy from time to time. Material changes will be posted here with a new "Last updated" date. Your continued use of the App after changes take effect constitutes acceptance.
