Pyramids Labs ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains our practices regarding information collection, usage, and storage when you use the GridSketch Pro Max mobile application (the "App").
By downloading and using the App, you agree to the terms of this Privacy Policy.
GridSketch Pro Max is engineered to operate completely offline.
All vector canvases, pixel coordinate maps, multi-layer configurations, color laboratory variables, and history recordings are processed and stored strictly on your local device.
We do not transmit, sync, or upload your creative designs or projects to any external servers, cloud databases, or third-party storage.
We firmly believe in your right to absolute storage privacy.
No Personal Data: The App does not require you to create an account, register, or provide any personal identification information (such as name, email address, phone number, or age).
No Analytics or Tracking: We do not integrate third-party analytics SDKs (such as Google Analytics or Firebase), tracking cookies, or diagnostic tools. Your app usage patterns and interaction history remain completely private to you.
No Advertising Data: GridSketch Pro Max is completely ad-free. We do not collect or share mobile advertising identifiers (like IDFA or AAID).
Any project details you save within the App are stored locally using Android’s native system storage parameters (SharedPreferences).
If you choose to export your designs as JSON, CSV, SVG, or ASCII vector markups, these are copied directly to your device's clipboard or saved to your local storage.
Deleting the App will permanently remove all locally stored design files, blueprints, and historical sequences from your device unless you have manually copied or backed up your exported code files elsewhere.
The App is built with minimal permission requirements:
Audio Feedback: We use the device's standard internal audio synthesis API (ToneGenerator) to produce responsive draw sounds. This does not require external microphone or recording permissions and operates completely locally.
