Privacy Policy

1. Information We Do Not Collect

Unlike traditional web services, we do not require account registration, email submission, or login credentials. Because our DPI inspection engine operates strictly client-side:

• We do not upload, view, or retain your image files (JPG, PNG, WebP, TIFF).
• We do not harvest personal metadata embedded in your images (such as GPS coordinates or camera serial numbers).
• We do not build user tracking profiles or sell any behavioral information to data brokers.

2. Client-Side Processing Architecture

Our application uses modern HTML5 and JavaScript technologies, including the FileReader and DataView APIs. When you interact with the tool:

• Binary headers (EXIF, JFIF, PNG pHYs, and TIFF IFD tables) are parsed directly in your device's volatile memory.
• As soon as you close or reload the browser tab, the temporary object references in your browser memory are discarded.
• The tool is capable of running completely offline once the page has loaded.

3. Local Storage and Cookies

We use local browser storage (localStorage) solely to remember your user interface preferences:

• theme: Remembers whether you prefer Dark Mode or Light Mode across visits.

We do not use tracking cookies, cross-site profiling cookies, or marketing trackers.

4. Third-Party Hosting and Content Delivery

Our static website files (HTML, CSS, JavaScript) are served via secure Content Delivery Networks (CDNs). Like virtually all web hosts, web servers may record standard technical server logs, including your IP address, browser type, referring URL, and timestamp for network security and DDoS mitigation. These server logs do not and cannot contain the contents of images processed by your browser.

5. External Links

Our website may contain hyperlinks to educational resources or specifications. If you click on an external link, you will be directed to that third party's website, which operates under its own independent privacy policy.

6. Children's Privacy

Our website does not knowingly collect personally identifiable information from children under the age of 13. Because our service collects zero personal data, children may safely use our image resolution calculation tool without data risks.

7. Updates to This Policy

We may update this Privacy Policy periodically to reflect changes in legal requirements or platform enhancements. Any modifications will be posted directly to this page with an updated revision date.
