Privacy Policy

We collect minimal data:

• Anonymous Analytics: Page views, tool usage, and general interaction patterns to improve our service. We use privacy-friendly analytics that don't track individual users.
• Technical Information: Browser type, device type, and screen resolution for optimization purposes.
• No Personal Information: We do not collect names, email addresses, or any personally identifiable information unless you explicitly contact us.

100% Local Processing:

• Text Diff: All text comparison happens in your browser using JavaScript. Your text never leaves your device.
• JSON Diff: JSON parsing and comparison execute locally. We never see your JSON data.
• Image Diff: Images are decoded and compared using HTML5 Canvas API in your browser. Your images are never uploaded to our servers.
• Before/After Slider: Image processing happens entirely on your device.

What this means: Even if we wanted to access your files, we technically cannot. The comparison logic runs entirely in your browser.

• No File Uploads: Your files are never uploaded to our servers or any third-party service.
• No Data Storage: We don't store your comparison results, files, or any content you input.
• No Tracking Cookies: We use minimal, privacy-friendly analytics without tracking cookies.
• No Third-Party Data Sharing: Your data never leaves your browser, so there's nothing to share.
• No Account Required: You can use all tools without creating an account or providing any personal information.

We use minimal browser storage:

• Essential Cookies: Small technical cookies for basic site functionality (e.g., remembering your preference for view mode).
• Analytics Cookie: A single cookie from our privacy-friendly analytics provider to distinguish unique visits.
• No Tracking: We don't use advertising cookies or cross-site tracking.

Your browser automatically clears any temporary data (Object URLs, Canvas data) when you close the page.

We use minimal third-party services:

• Hosting: Cloudflare Pages (for serving the website)
• Analytics: Privacy-friendly analytics (Plausible or similar) that doesn't track individual users
• CDN: Content delivery network for faster page loads

None of these services have access to your comparison files or content.

Since we don't collect personal data, there's minimal data to manage. However:

• Access: You can use browser developer tools to see what minimal data is stored locally.
• Deletion: Clear your browser cookies and cache to remove any stored preferences.
• Opt-out: Use browser settings or privacy extensions to block analytics if desired.

We may update this privacy policy from time to time. We will notify you of any changes by posting the new policy on this page with an updated "Last updated" date.

We encourage you to review this policy periodically for any changes.
