100% Local Processing Guarantee

Kavrylo is built with a privacy-first architecture. Your identity documents, passports, and PDFs are processed entirely inside your web browser. No files are ever uploaded, stored, or transmitted to any server.

1. Legal Notice (Mentions Légales)

In accordance with standard digital publication requirements, please find below the corporate and hosting identification details for this website:

  • Website Owner & Publisher: Antoine Viala
  • Director of Publication (Directeur de la publication): Antoine Viala
  • Contact Information: For any legal inquiries or support requests, please contact contact@kavrylo.me.
  • Web Hosting Provider (Hébergeur): This website is hosted completely by Neocities (Neocities LLC, USA). Website: neocities.org.

2. Document Data and Processing

When you select an image or a PDF document to watermark on Kavrylo, the application relies exclusively on standard client-side browser features (the HTML5 Canvas API) and local JavaScript libraries (PDF.js and PDF-lib). Because processing happens purely on your local machine, we cannot access, view, or retain your documents under any circumstances.

3. Third-Party Services We Use

While your files never leave your device, Kavrylo uses a few standard external tools to ensure site performance, compliance, and sustainability:

  • CookieYes: We use this consent management platform to let you control your cookie preferences dynamically, in accordance with global privacy frameworks like GDPR.
  • Google Analytics (G-8F3D2930VT): We use this service to understand general aggregated metrics such as page views, duration of visits, and device types. It tracks anonymized usage statistics but does not have access to your documents or personalized data.
  • Google AdSense: To support this free service, we display contextual ads. Google AdSense may use cookies or device identifiers to serve tailored ads based on your web browsing history.

4. Cookies and Tracking Technologies

Cookies are tiny files stored on your device. Kavrylo uses essential cookies to save your user settings and non-essential analytics/advertising cookies provided by foreign scripts (as mentioned above). You can adapt or fully withdraw your consent at any time via the CookieYes interactive widget layout on our site.

5. Data Rights & General Inquiries

Since we do not collect personal profiles, email addresses, or uploaded document data, we do not possess any personal archives to delete or alter upon request. For general questions about how the local canvas engine processes information, please reach out via our official contact address.

6. Changes to This Policy

We may update this Privacy Policy from time to time to mirror potential revisions to client-side features or standard operations. Any edits will be made transparent on this link with an updated timestamp.
