Aspect Ratio Calculator
Legal & Transparency

Privacy Policy

Last updated: September 2026. We believe privacy should be the default on the modern web.

1. Our Privacy Philosophy: Client-Side by Design

Aspect Ratio Calculator is engineered from the ground up as a completely static, client-side application. When you use this website to compute aspect ratios, calculate dimensions, or inspect images, all computation happens exclusively within your browser’s JavaScript engine.

We do not own, operate, or maintain any backend servers or databases that collect or store your inputs. Your data never leaves your device.

2. Image Processing Privacy Guarantee

When you drag-and-drop, upload, or paste (Ctrl+V) an image into the calculator:

  • The image file is loaded strictly into your local browser memory using the standard HTML5 URL.createObjectURL() API.
  • The browser reads the intrinsic naturalWidth and naturalHeight properties of the image element to calculate its aspect ratio.
  • No image data, filenames, or EXIF metadata are ever transmitted to any server, third party, or cloud storage.
  • When you close the tab or click the clear (×) button, the temporary in-memory object URL is immediately revoked and deleted from your system RAM.

3. Cookies and Analytics

We take a strict anti-tracking stance:

  • No Tracking Cookies: We do not set any tracking, advertising, or cross-site cookies.
  • No Third-Party Analytics: We do not load Google Analytics, Facebook Pixels, or intrusive session recording scripts.
  • Local Storage: We utilize a single item in your browser’s localStorage named theme to remember whether you prefer Dark Mode or Light Mode across visits. No personal identifiers are stored.

4. Edge Hosting via Cloudflare Pages

This website is hosted on Cloudflare Pages. Like standard web servers, Cloudflare may temporarily process standard network routing information (such as your IP address and user-agent) to deliver static assets and protect against DDoS attacks, governed by Cloudflare’s Privacy Policy. We have zero access to personally identifiable server logs.

5. Changes to This Policy

Should we ever introduce new features, this policy will be updated accordingly. However, our foundational commitment to 100% client-side privacy will never change.
