Symmetry Pattern Lab ("we", "our", or "us") respects your privacy. This Privacy Policy explains how our mobile application handles user information and data.
By using Symmetry Pattern Lab, you agree to the collection and use of information in accordance with this policy.
1. Information Collection and Use
Symmetry Pattern Lab is designed with privacy first.
•
No Personal Data Collection: We do not collect, store, transmit, or request any personally identifiable information (such as your name, email address, phone number, location, or contacts).
•
No User Account Required: You can use all features of Symmetry Pattern Lab without registering an account or providing any personal details.
2. Photo & Image Data Handling (Local Device Processing)
To generate seamless patterns, Symmetry Pattern Lab allows you to select photos or graphics from your device:
•
100% Local Processing: All image cropping, symmetry math transformations, tile rendering, and color effect adjustments happen entirely locally on your device.
•
No Image Uploads: Your photos, artwork, and generated pattern files are never uploaded to external servers, cloud storage, or third-party databases.
•
Private Project Storage: When you save a favorite pattern project inside the app, the source image copy and project parameters are stored in your device's private app storage directory (context.filesDir). This data remains completely private to you on your device.
3. Third-Party Services & Advertising (Google AdMob)
Symmetry Pattern Lab uses Google AdMob to display banner advertisements. Google AdMob may use pseudonymous identifiers (such as the Android Advertising ID) to serve ads and measure ad performance in compliance with Google Play Developer Policies.
AdMob’s use of data is governed by Google’s Privacy Policy:

•
Google AdMob Terms & Policies
4. Device Permissions
Symmetry Pattern Lab requests minimal device permissions strictly necessary for its functionality:
•
Photo / Media Picker Access (GetContent): Required only when you explicitly choose to select an image from your device gallery to generate a pattern.
•
Save to Storage / Gallery (MediaStore): Required only when you explicitly choose to save your exported high-resolution pattern artwork or seamless tiles to your device's Pictures folder.
•
File Sharing (FileProvider): Used temporarily when you explicitly tap the "Share" button to share a pattern image file and message with another app (such as WhatsApp, Instagram, or email).
5. Children's Privacy
Symmetry Pattern Lab does not knowingly collect any personal information from children under the age of 13. Since the app processes images locally and collects no personal data, it is safe for general audiences.
6. Security
We value your trust in using Symmetry Pattern Lab. Because all core image processing and design saving happen locally on your phone, your creative work remains securely stored on your own device.
7. Changes to This Privacy Policy
We may update our Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last Updated" date.
