Smart TechDev Studio ("we", "us", or "our") respects your privacy and is committed to protecting your information when you use our applications. This Privacy Policy applies to Android applications published and operated by Smart TechDev Studio through Google Play (collectively, "our Apps").

This Privacy Policy explains how we collect, use, process, share, and protect user information. Since different Apps may have different features and configurations, actual data practices may vary depending on the specific App version and functionality.

1. Information We Collect

To provide App functionality, improve service quality, and maintain App stability, we or our integrated third-party services may collect certain device and usage information.

Such information may include device model, operating system version, device language, country or region information, network information, IP address, device identifiers, Android Advertising ID, App usage information, operation logs, crash reports, diagnostic data, and performance information.

When users use our App features, we may process information voluntarily provided by users, such as video links entered by users, download task information, download status, and user-selected file storage locations.

We do not intentionally collect users' video content, third-party platform account passwords, or authentication information used to access third-party platforms.

2. How We Use Information

We may use collected information to provide and maintain App functionality, process user-initiated download requests, display download status, improve App performance and stability, analyze App usage, enhance user experience, deliver and measure advertisements, detect abnormal activities, prevent fraud, and maintain App security.

We may also process information when required by applicable laws and regulations.

We do not use collected information for purposes materially inconsistent with those described in this Privacy Policy.

3. Permissions, Local Processing, and Downloaded Content

Depending on App functionality, we may request access to certain device permissions.

Storage or media access permissions may be used to save downloaded video files, read download status, and manage local files selected by users. Network access permissions are used to access network services, process download requests, perform video download tasks, load App content, and provide related services. Notification permissions may be used to provide download completion reminders, task status updates, or other App-related notifications. Some Apps may use foreground services or background execution permissions to ensure that user-initiated download tasks continue running properly.

We only request permissions necessary for providing App functionality and do not access information unrelated to video downloading features.

Certain App features, such as file saving, download task management, and downloaded file management, may be processed locally on the user's device. Unless a feature explicitly requires it, we do not upload users' downloaded video files to our servers.

Our Apps may allow users to download video content by entering links, using in-App browsing features, or through other supported methods. Users are responsible for ensuring that downloading, saving, using, or sharing video content complies with applicable laws and third-party platform terms of service.

We do not own, host, control, or represent any video content downloaded by users through our Apps, and we are not affiliated with any third-party video platforms, social media platforms, or content providers. Users should independently confirm whether they have the legal right to download, save, or use such content.

We do not access downloaded video content unless required by App functionality, such as saving files, managing download tasks, or providing features explicitly requested by users.

4. Third-Party SDKs and Services

Our Apps may integrate third-party SDKs for advertising, privacy choice management, analytics, performance monitoring, and App optimization.

These third-party services may collect and process certain information according to their own privacy policies, such as device information, IP address, Advertising ID, App usage data, and advertising interaction data.

These third-party SDKs process information according to their own privacy policies.

5. Advertising Services

Some Apps may display third-party advertisements.

We use advertising services primarily to support App operations, display relevant advertisements, and improve advertising experience.

Where required by applicable laws, we use Google User Messaging Platform (UMP) or other appropriate mechanisms to provide users with advertising privacy choices.

Users can manage advertising preferences through privacy settings within the App and Android system settings.

6. Data Sharing, Security, and Retention

We do not sell, rent, or trade users' personal information.

Certain information may be processed by third-party service providers that support our Apps, such as advertising providers, analytics services, and technical service providers. These services may process limited information, including device information, IP address, Advertising ID, and App usage data, only for providing their related services, such as displaying advertisements, measuring performance, analyzing App usage, and improving service reliability.

Downloaded files and media content selected or saved by users are generally stored locally on the user's device. We do not store or access users' downloaded video files on our servers unless a specific feature explicitly requires such processing.

We take reasonable measures to protect information handled by our Apps, including applying appropriate technical safeguards and limiting access to collected data. However, no online service or electronic storage method can guarantee complete security.

Information is retained only for the period necessary to provide services, maintain App functionality, comply with legal obligations, resolve disputes, or enforce applicable agreements. Data handled by third-party providers is retained according to their respective privacy policies and data retention practices.

7. User Privacy Rights

Depending on applicable laws, users may have rights to access, correct, delete, or restrict the processing of their personal information.

Where GDPR applies, users may have rights to access, correct, delete, restrict processing, object to processing activities, and request data portability.

Where CCPA/CPRA applies, California residents may have rights to know, access, delete personal information, and opt out of the sale or sharing of personal information where applicable.

We do not sell users' personal information.

To exercise applicable privacy rights, users may contact us through the email address below.

Updates and Contact Information

Some Apps may provide subscriptions, in-app purchases, or other paid services.

Payments are generally processed through Google Play Billing. We do not directly collect or store users' complete payment card information.

Subscription details, pricing, billing periods, and purchase conditions are displayed within the App purchase page and Google Play page.

We may update this Privacy Policy from time to time due to changes in legal requirements, third-party SDKs, business operations, or App functionality.

The latest version and update date will be published on this page.
