Welcome to Rectangular Mosaic (“we,” “us,” “our,” or “the App”). We understand the importance of your personal information and are fully committed to protecting your privacy and security. We strive to maintain your trust by adhering to the following principles: lawfulness, fairness, and transparency; purpose limitation; data minimization; accuracy; storage limitation; integrity and confidentiality; and accountability.

This Privacy Policy is designed to help you understand what information we collect, how we use it, and what choices you have.

Please read this Privacy Policy carefully before using the App.

1. Information We Collect and How We Use It

To provide our services, we collect and use your information based on the following core functions:

a) Core Image Processing (Offline Functionality)

The core function of this App is to provide you with image mosaic processing services. This functionality operates entirely locally on your device.

• Camera Permission: When you choose the “Take Photo” feature, we will request your camera permission. This permission is used solely for taking a photo for immediate editing within the App. We do not store or share your photos.
• Photo Library / Storage Permission: When you choose to “Select from Gallery” or need to save your processed images, we will request permission to read and write to your photo library or device storage. This permission is used only to access the images you select for editing and to save your finished work back to your device. All of your image files are processed locally on your device and are never uploaded to our servers or any third-party servers.

b) Third-Party Services

Some services within the App are provided by third-party SDKs. When you use these services, these third parties may collect some of your information.

• Advertising Services (Google AdMob): To keep the App free, we have integrated the Google AdMob SDK to display advertisements. During this process, Google AdMob may collect your device information (e.g., device model, operating system version), IP address, device identifiers (such as IDFA and GAID), and ad interaction data to serve personalized ads and for ad performance analysis. We do not provide Google AdMob with any information that can directly identify you personally. For more information on how Google AdMob collects and processes your data, you can review Google’s Privacy & Terms. You can also limit personalized ad tracking through your device’s system settings (the “Tracking” setting on iOS or the “Ads” setting on Android).
• App Update Service: To ensure you receive timely feature and security updates, the App checks for new versions upon launch. This process involves a network request to our update server, which may log your IP address. We use this information for statistical and security purposes only and do not link it to your other personal information.

2. Device Permissions We Request

To ensure the proper functioning of the App, we may request the following device permissions:

• CAMERA: To use the camera for taking photos to edit.
• STORAGE / PHOTOS (READ/WRITE_EXTERNAL_STORAGE, READ_MEDIA_IMAGES): To read image files from your device and to save your edited images back to your device.
• INTERNET: To fetch ad content and to check for new versions of the App.

You can manage or withdraw these permissions at any time through your device’s system settings. Please note that disabling certain permissions may affect your ability to use some features of the App.

3. Data Storage and Security

• Storage Location: As stated above, your core personal data, such as images, is stored only on your local device.
• Security Measures: We implement industry-standard security technologies and measures to protect the information handled by third-party services (like the AdMob SDK) from loss, misuse, unauthorized access, or disclosure.

4. Children’s Privacy

This App is intended for a general audience and is not directed to children under the age of 13 (or the relevant age in your jurisdiction). We do not knowingly collect personal information from children. If you are a parent or guardian and believe that your child has provided us with personal information, please contact us using the details below, and we will take steps to delete such information promptly.

5. Your Rights and Choices

You have control over your personal information. You can manage your ad preferences and app permissions through your device’s system settings. If you have any questions or requests regarding this Privacy Policy or your personal information, please contact us.

6. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated effective date. We encourage you to review this page periodically for the latest information on our privacy practices. For significant changes, we may notify you through an in-app notification.
