Privacy Policy

Jetella ("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.

Jetella is an entertainment app that streams short, vertical drama series — romance, CEO/billionaire, mafia, werewolf, revenge and more — in bite-sized episodes. You do not need to create an account, sign in, or give us your name or email to use it: the App authenticates to our content provider anonymously using a randomly generated device session identifier.

1. Information we collect

We collect only what is needed to run, secure, monetize and improve the App. We do not ask you for your name, email address, phone number, photos, contacts, files or precise GPS location, and the App requests no such permission.

Collected automatically

• Device and advertising identifiers — the Google Advertising ID (the App declares the com.google.android.gms.permission.AD_ID permission), the Android App Set ID, and a randomly generated session identifier sent to our content provider. These are used for advertising, measurement, anti-fraud and attribution.
• Device and technical information — device model and brand, operating-system version, app version, app language and interface locale, time zone, and network connection state.
• Approximate location derived from IP address — country/region level only, used by our advertising and analytics partners for ad delivery, measurement and legal compliance. The App does not use any location permission or GPS/geolocation SDK.
• App activity — screens viewed, series and episodes opened, playback and progress events, interactions with ads (including rewarded ads), and onboarding choices, logged through Firebase Analytics.
• In-app search terms — the keywords you type in Search are sent to our content provider so it can return matching series. They are not linked to your name or to an account.
• Crash logs and diagnostics — stack traces, device state at the time of a crash and non-fatal error reports, collected by Firebase Crashlytics in release builds.
• Integrity and anti-tampering signals — Firebase App Check (Play Integrity) attestation tokens attached to content requests, and device-integrity signals from our anti-tampering component (for example, whether the app binary or signing certificate has been modified, or whether the device appears rooted or emulated). These are used solely to protect our content APIs from abuse and unauthorized redistribution.

Stored only on your device (not transmitted to us)

• Your chosen interface language, subtitle preference, onboarding state, liked series, watch progress and coin balance are saved in local storage on your device. Uninstalling the App deletes them. We do not hold a server-side copy tied to you.

2. How we use information

• Provide, operate and maintain the App, stream drama content and return search results.
• Remember your language, subtitle choice, liked series and the exact episode and position you stopped at.
• Display advertising, including rewarded ads that grant in-app coins, and measure ad performance.
• Attribute app installs and in-app events to marketing campaigns.
• Analyze usage to understand which features and content are used and to improve the App.
• Detect, prevent and investigate fraud, abuse, content piracy, tampering and security incidents.
• Comply with legal obligations and enforce our Terms of Service.

We do not use your information to make automated decisions that produce legal effects about you.

3. Third-party services

The following data-transmitting services are integrated in the App. Each operates as an independent controller or processor for the data it receives, under its own privacy policy:

Ad consent (EEA/UK and other consent regions). The App uses Google's User Messaging Platform (UMP) to request your consent before loading personalized ads where consent is required. You can change or withdraw your choice at any time from the privacy options available in the consent form.

Advertising ID controls. You can reset your Google Advertising ID or opt out of ad personalization at any time in Android Settings → Google → Ads. Opting out does not remove ads; it makes them less relevant.

Notifications. The App may ask for permission to send notifications (POST_NOTIFICATIONS) and uses local, on-device reminders only — for example, a reminder if you have not finished setting up the App or have not opened it for a while. These are scheduled on your device and do not involve push messaging or a server-side contact list.

4. How we share information

We do not sell your personal information for money. We share data only:

• with the third-party services listed in Section 3, for the purposes stated there;
• for legal reasons — to comply with applicable law, legal process or a valid government request, or to protect our rights, users and the security of our services;
• in connection with a merger, acquisition or other business transfer, subject to this Policy.

U.S. state privacy laws. Where personalized advertising is enabled, sharing your advertising identifier and ad-interaction data with advertising partners may be treated as a "sale" or "sharing" / "targeted advertising" under laws such as the CCPA/CPRA and similar state statutes. You may opt out at any time using the Android advertising-ID controls described in Section 3, by declining consent in the UMP form where it is shown, or by contacting us at the address in Section 13.

5. Legal bases (EEA/UK — GDPR)

• Consent — personalized advertising and, where required, analytics; notification permission.
• Legitimate interests — operating and securing the App, non-personalized advertising and measurement, fraud and piracy prevention, product improvement.
• Legal obligation — retaining records and responding to lawful requests.

6. Data retention

We retain data only as long as necessary for the purposes above or as required by law. Advertising and analytics identifiers are retained by our partners under their own retention schedules (see their policies in Section 3); Firebase Analytics data is retained according to the retention setting configured in our Firebase project. Crash and diagnostic reports are kept for a limited period for debugging. Preferences, liked series, watch progress and coin balance live on your device and are removed when you uninstall the App or clear its storage.

7. Your rights

EEA/UK (GDPR). You have the right to access, correct, delete, port, object to or restrict the processing of your personal data, to withdraw consent at any time, and to lodge a complaint with your local data protection authority.

California (CCPA/CPRA). You have the right to know what personal information is collected and how it is used and disclosed, to delete it, to correct it, to opt out of its sale or sharing and of targeted advertising, and not to be discriminated against for exercising these rights.

Other regions. Comparable rights exist under laws such as Brazil's LGPD, Canada's PIPEDA and similar frameworks, and we honour them on request.

How to exercise your rights. Email us at the address in Section 13. Because the App has no accounts, we cannot identify you by name — please include your Google Advertising ID and your device model and operating-system version so we can locate the relevant records with our partners. You can also delete all locally stored data yourself by uninstalling the App or clearing its storage in Android Settings.

8. Children's privacy

The App is intended for users aged 18 and over and is not directed to children. Some drama content includes mature romantic and dramatic themes. We do not knowingly collect personal information from children under this age (or the higher age of digital consent that may apply in your region). The App has no chat, messaging, comments, profiles or any other feature that lets users communicate with each other or upload content. If you believe a child has provided us personal information, contact us at contact@tranquilmind.co 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 rely on appropriate safeguards (such as Standard Contractual Clauses) for these transfers.

10. Data security

We use encryption in transit (HTTPS/TLS) for all network requests, request signing and Play Integrity attestation on our content APIs, and other reasonable technical and organizational measures to protect your data. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.

11. Third-party content

All drama series, episodes, artwork, titles, synopses and cast information in the App are supplied and streamed by a third-party content provider and are the property of their respective rights holders. We do not host this content and do not control it; catalogue availability may change at any time without notice. We are not responsible for the content, accuracy or privacy practices of third-party services or links. Please review their policies before interacting with them.

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 of the updated Policy.
