Privacy Policy

1. Introduction

GridMaster is an online grid drawing tool created to help artists, sketchers, and painters create proportional grids on reference images. We are committed to transparency and respecting your digital privacy. This policy explains what happens when you visit and use our website at gridmastertool.com.

2. Client-Side Image Processing

All image editing, grid application, scaling, cropping, rotation, and export generation occur strictly on your device inside your web browser. When you upload or drag a photo into GridMaster, the image data is processed using client-side JavaScript and the HTML5 Canvas API.

Your images are never uploaded to our servers, never stored remotely, and never visible to us or any third party.

3. Information We Do Not Collect

Because GridMaster is a client-side utility:

• No account registration or personal profile is required to use the tool.
• We do not collect names, passwords, phone numbers, or physical addresses.
• We do not store or monetize your uploaded reference artwork or drawing photos.

4. Local Browser Storage

GridMaster may store non-sensitive tool preferences (such as your chosen grid line color, cell dimension, line thickness, or label visibility) in your browser local storage (localStorage). This data never leaves your device and serves solely to remember your preferred settings during future visits. You can clear this data at any time via your browser settings.

5. Hosting & Technical Logs

Like virtually all internet websites, our hosting infrastructure may temporarily log standard HTTP technical data (such as browser user-agent, referring URL, date/time stamp, and approximate IP address) solely for diagnosing technical errors, preventing abuse, and guaranteeing network security.

6. Contact Inquiries
