1. Introduction

ROTUNDA TECH LTD ("Company", "we", "our", or "us") operates CastBrowser ("App", "Service"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application.

Please read this Privacy Policy carefully. By using the App, you agree to the collection and use of information in accordance with this policy.

2. Information We Collect

2.1 Information Stored Locally on Your Device

The App stores certain data locally on your device to provide its functionality:

• Browsing data: History, bookmarks, and session data you create while using the built-in browser
• WebView storage: Cookies, site data, and cached content from websites you visit through the App
• App preferences: Your settings and configuration choices
• Casting session data: Information needed to connect to and control your casting devices

This local data remains on your device and is not transmitted to our servers. You can clear this data at any time through the App settings or by uninstalling the App.

2.2 Information Collected Automatically

When you use the App, we automatically collect certain information through third-party services:

• Analytics data: App usage patterns and feature interactions (via Firebase Analytics). We do not log full URLs in analytics; we log domain-level information.
• Device information: Device type, operating system version, app version, and general device identifiers
• Crash and error reports: When errors occur, we collect diagnostic information (such as device state, logs, view hierarchy, and information about the connected casting device like device type and device name) to help us identify and fix issues (via Sentry). This may also include a screenshot and an on-error session replay of the app UI (captured only when an error occurs), which may include on-screen content.

2.3 Network and Casting Information

To provide casting functionality, the App discovers devices on your local network:

• Local network discovery: The App scans your local network to find compatible casting devices (Chromecast, DLNA/UPnP devices)
• Device information: IP addresses and device names of casting devices on your network are processed locally to enable casting

This network information is processed on your device to enable casting. We do not transmit your local network scan results to our servers as part of normal operation.

2.4 Information You Provide

When you contact us for support, we receive the information you provide in your message, which may include your email address, device information, and app version that you choose to share.

2.5 Purchases and Subscriptions

The App does not currently offer subscriptions, one-time purchases, or in-app purchases. If we introduce paid features in a future release, payment processing will be handled entirely by the relevant app store (Google Play or Apple App Store), and we will update this Privacy Policy before those features go live.

2.6 Content Filtering Rules

The App may periodically download content filtering rules from our servers. These requests are subject to standard server logging (IP address, request time, device type) for security and operational purposes.

2.7 Search Suggestions

When you type in the App's address bar, your input is sent in real-time to Google's autocomplete service (suggestqueries.google.com) to provide search suggestions. This means:

• Search queries: Text you type in the address bar is transmitted to Google
• IP address: Your device's IP address is visible to Google along with your queries
• Real-time transmission: Data is sent as you type, not just when you submit a search

This data is processed by Google and is subject to Google's Privacy Policy. We do not store or have access to the search suggestion queries you make.

3. How We Use Your Information

We use the information we collect for the following purposes:

• To provide the Service: Enable browsing, video detection, and casting functionality
• To improve the App: Analyze usage patterns to enhance features and user experience
• To fix issues: Diagnose and resolve crashes, errors, and technical problems
• To communicate: Respond to your support requests and inquiries
• To ensure security: Protect against fraud and maintain service integrity

4. Legal Bases for Processing (EEA/UK Users)

If you are located in the European Economic Area (EEA) or United Kingdom (UK), we process your personal data based on the following legal grounds:

• Contract performance: Processing necessary to provide the Service you requested (browsing, video detection, and casting)
• Legitimate interests: Analytics, crash reporting, and service improvement, where our interests do not override your rights
• Consent: For optional features or permissions where consent is required by law
• Legal obligations: Where required to comply with applicable laws

Note: The App does not currently use personalized advertising. If that changes in the future, we will present any required consent flow before enabling it.

5. Advertising

The App does not currently display third-party advertisements or use ad monetization SDKs. If we introduce advertising in a future version, we will update this Privacy Policy before the change takes effect and provide any consent or opt-out disclosures required by law.

6. Third-Party Services

The App uses the following third-party services that may collect information:

• Google Analytics for Firebase: For usage analytics - Firebase Privacy
• Sentry: For crash and error reporting - Sentry Privacy Policy
• Google Play Services: For app distribution, licensing, and related platform services - Google Privacy Policy

When you browse websites using the App, those websites may have their own privacy policies and may collect data according to their terms. The App's WebView stores cookies and site data from these websites locally on your device. We recommend reviewing the privacy policies of websites you visit.

7. Data Sharing and Disclosure

We do not sell your personal information. We may share information in the following circumstances:

• Service Providers: With third-party vendors who assist in operating the App (analytics and crash reporting)
• Legal Requirements: If required by law or in response to valid legal processes
• Business Transfers: In connection with a merger, acquisition, or sale of assets

8. Data Security

We implement appropriate technical and organizational measures to protect your information. However, no method of transmission over the Internet or electronic storage is 100% secure, and we cannot guarantee absolute security.

9. Data Retention

We retain information for as long as necessary to provide the Service and fulfill the purposes described in this Privacy Policy:

• Analytics data: Retained according to Firebase's retention policies (typically 14 months)
• Crash reports: Retained according to Sentry's data retention settings (typically up to 90 days)
• Local device data: Retained until you clear it through App settings or uninstall the App

10. Children's Privacy

The App is not intended for children under 13 years of age (or 16 in some jurisdictions). We do not knowingly collect personal information from children. If you are a parent or guardian and believe your child has provided us with personal information, please contact us and we will delete such information.
