Privacy Policy

Last Updated: February 22, 2026

1. Introduction

Welcome to TianDev Studio ("we", "our", or "us"). We are committed to protecting your personal information and your right to privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile applications available on the Apple App Store and Google Play Store (collectively, the "Apps").

Please read this policy carefully. If you disagree with its terms, please discontinue use of our Apps.

2. Information We Collect

We may collect the following types of information depending on which App you use:

Information You Provide Directly

• Account registration details (e.g., name, email address) where applicable
• Content you create, upload, or process within the Apps (e.g., documents, photos, audio files)
• Feedback, support requests, or communications you send us
• In-app purchase and subscription information (processed by Apple App Store or Google Play)

Information Collected Automatically

• Device information (device model, operating system version, unique device identifiers)
• Usage data (features used, session duration, crash reports, performance diagnostics)
• IP address and approximate geographic location (country/region level)
• Advertising identifiers (IDFA on iOS, GAID on Android) when advertising is enabled

Information from Third Parties

• Analytics data from Firebase (Google Analytics for Firebase)
• Crash reports from Firebase Crashlytics
• Advertising data from Google AdMob and associated ad networks

3. How We Use Your Information

We use the information we collect to:

• Provide, operate, and maintain our Apps and their features
• Process in-app purchases and manage subscription access
• Improve, personalize, and expand our Apps' functionality
• Understand and analyze how users interact with our Apps
• Develop new products, services, and features
• Send you technical notices, updates, security alerts, and support messages
• Respond to your comments, questions, and support requests
• Display relevant advertisements (where applicable) and measure ad performance
• Detect, prevent, and address fraud, security issues, and technical problems
• Comply with legal obligations

4. Data Processing and Storage

Most of our Apps process your data locally on your device. Files and content you work with (such as documents, audio, or images) are processed on-device and are not uploaded to our servers unless a specific feature explicitly requires it.

Aggregated, anonymized analytics data may be transmitted to and stored on servers operated by our trusted third-party partners (e.g., Google Firebase) located in the United States and other countries. We ensure appropriate data transfer mechanisms are in place for international transfers.

5. Advertising and Third-Party Services

Our free Apps may display advertisements served by Google AdMob and its partner networks. These services may use cookies, device identifiers, and similar technologies to serve ads tailored to your interests.

Advertising is disabled for users who have an active paid subscription within the App.

Third-party ad partners we may work with include:

• Google AdMob / Google Ad Manager
• Meta Audience Network
• AppLovin
• Unity Ads

These partners have their own privacy policies governing their data practices. We encourage you to review them. You can opt out of personalized advertising on iOS via Settings > Privacy & Security > Tracking, and on Android via Settings > Google > Ads.

6. Children's Privacy

Our Apps are not directed to children under the age of 13 (or 16 in the European Economic Area). We do not knowingly collect personal information from children under these ages. If you are a parent or guardian and believe your child has provided us with personal information, please contact us immediately and we will take steps to remove such information.

7. Data Retention

We retain your personal information only for as long as necessary to fulfill the purposes described in this Privacy Policy, unless a longer retention period is required or permitted by law. Analytics data is typically retained for 14 months. You can request deletion of your data at any time by contacting us.

8. Your Rights and Choices

Depending on your location, you may have the following rights regarding your personal information:

• Access: Request a copy of the personal data we hold about you
• Correction: Request correction of inaccurate or incomplete data
• Deletion: Request deletion of your personal data ("right to be forgotten")
• Portability: Request transfer of your data in a machine-readable format
• Objection: Object to processing of your data for certain purposes
• Opt-out of targeted advertising: Use your device's privacy settings to limit ad tracking

To exercise any of these rights, please contact us using the information in the Contact Us section below.

9. Security

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

10. Links to Third-Party Services

Our Apps may contain links to third-party websites or services. We are not responsible for the privacy practices of those third parties. We encourage you to review their privacy policies before providing any personal information.

11. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of any material changes by updating the "Last Updated" date at the top of this page, and where appropriate, by providing notice within the App. Your continued use of our Apps after any changes constitutes your acceptance of the updated policy.
