Privacy Policy

Jade Browser ("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.

Jade Browser is a lightweight web browser with a built-in ad and pop-up blocker. You do not need to create an account to use it.

Your browsing stays on your device. The web pages you visit, your history, tabs, and data you enter into websites are processed on your device and are not transmitted to us. This Policy covers only the limited data described below that our third-party SDKs send off the device.

1. Information We Collect

We do not ask you to provide personal information such as your name, email, or phone number. The App and its integrated third-party services automatically collect the following limited data:

• Device and advertising identifiers — including your device's advertising ID (AAID), device model, operating system version, and similar technical identifiers, used mainly for advertising and analytics.
• Approximate location — coarse location inferred from your IP address by our advertising partners for ad targeting and measurement. We do not collect precise/GPS location, and the App does not request any location permission.
• App activity — in-app interactions and events (screens viewed, buttons tapped, features used) collected for analytics. This does not include the websites you browse.
• Crash logs and diagnostics — crash reports, error logs, and performance data to help us fix problems and improve stability.
• Purchase status — records of in-app purchases and subscription status (processed by Google Play Billing) so we can unlock ad removal and provide support.

2. How We Use Information

We use the information above to:

• Provide, operate, and maintain the App;
• Display and measure advertising (including personalized ads where you have consented);
• Understand usage through analytics and improve the App;
• Detect, prevent, and address fraud, abuse, and security issues;
• Process and validate in-app purchases and subscriptions;
• Comply with legal obligations.

3. Third-Party Services

The App integrates the following third-party services, which may collect and process data as described in their own privacy policies:

• Google Firebase (Analytics, Crashlytics, Remote Config) — analytics, crash reporting, remote configuration — Privacy policy
• Google AdMob — advertising — Privacy policy
• Meta Audience Network (ad mediation) — advertising — Privacy policy
• AppLovin, Unity Ads, Pangle, Mintegral, IronSource, LiftOff (Vungle), InMobi (ad mediation) — advertising — AppLovin · Unity · Pangle · Mintegral · IronSource · LiftOff (Vungle) · InMobi
• Adjust — attribution and analytics — Privacy policy
• Meta (Facebook) SDK — attribution — Privacy policy
• Google Play Billing — purchase processing — Privacy policy

Advertising consent (GDPR / UMP)

In the European Economic Area, the United Kingdom, and other regions where required, we present a consent request using Google's User Messaging Platform (UMP) before showing personalized ads. Your choice determines whether you see personalized or non-personalized advertising. You can change or withdraw your consent at any time from within the App's settings.

Resetting or limiting your advertising ID

You can reset your advertising ID or opt out of ad personalization at any time in your device settings (Android: Settings → Privacy → Ads; iOS: Settings → Privacy & Security → Tracking / Apple Advertising).

4. How We Share Information

We do not sell your personal information for money. We share data with the third-party services listed in Section 3 so they can perform advertising, analytics, attribution, and payment processing on our behalf or for their own purposes as described in their policies. We may also disclose information to comply with the law, enforce our terms, or in connection with a merger, acquisition, or sale of assets.

U.S. state privacy notice. Because we use partners that serve personalized ads, the sharing of advertising and device identifiers for targeted advertising may be considered a "sale" or "sharing" of personal information under certain U.S. state laws (e.g. California's CCPA/CPRA). You may opt out of personalized ads as described in Sections 3 and 7.

5. Legal Bases (EEA/UK — GDPR)

• Consent — for personalized advertising and, where required, analytics.
• Legitimate interests — for core functionality, non-personalized ads, security, fraud prevention, and product improvement.
• Contract / legal obligation — for processing purchases and complying with law.

6. Data Retention

We and our partners retain data only as long as necessary for the purposes described or as required by law. Advertising and analytics identifiers are retained according to each partner's retention schedule; crash and diagnostic data are retained for a limited period needed to diagnose and fix issues.

7. Your Rights

Depending on where you live, you may have rights to access, correct, delete, port, or restrict processing of your personal information, to object to processing, and to withdraw consent.

• EEA/UK (GDPR): access, rectification, erasure, portability, restriction, objection, withdrawal of consent, and the right to lodge a complaint with your data protection authority.
• California (CCPA/CPRA): the right to know, delete, and correct personal information, to opt out of the sale/sharing of personal information and targeted advertising, and to non-discrimination for exercising your rights.
• Other regions (e.g. LGPD, PIPEDA): equivalent rights under your local law.

Because the App has no user accounts, please include your device advertising ID and device details when you contact us so we can identify the relevant data. Contact us at contact@tranquilmind.co.

8. Children's Privacy

The App is intended for users 18 years of age or older and is not directed to children. We do not knowingly collect personal information from children. If you believe a child has provided us information, contact us and we will take appropriate steps to delete it.

9. International Data Transfers

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

10. Data Security

We use encryption in transit (HTTPS/TLS) and other reasonable technical and organizational measures to protect information. However, no method of transmission or storage is 100% secure, and we cannot guarantee absolute security.

11. Third-Party Content

Jade Browser lets you access third-party websites and content. We do not create, control, or endorse that content and are not responsible for it or for the privacy practices of the sites you visit. Please review the policies of any website you use.

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.
