Privacy Policy

How we protect your privacy when using our Vegan E-Number Checker

Last updated: July 29, 2025

Privacy-First Approach

🔒 Your Data Stays on Your Device

Our Vegan E-Number Checker is designed with privacy as a core principle. All processing happens directly in your browser - we never see, store, or transmit your images or text data to our servers.

What We Do NOT Collect

📷 Images

Images you upload are processed entirely in your browser using client-side OCR technology. They never leave your device.

📝 Text Data

Ingredient text you enter is analyzed locally in your browser. We do not store or transmit this information.

🔍 Search Results

E-number analysis results are generated in your browser and are not saved or tracked by us.

👤 Personal Information

We do not require accounts, emails, or any personal information to use our service.

How Our Technology Works

Our Vegan E-Number Checker uses modern web technologies to provide a completely private experience:

  • Client-Side OCR: Image text extraction happens in your browser using Tesseract.js, without server communication.
  • Local Processing: E-number identification and vegan status checking occurs entirely on your device.
  • Static Hosting: Our website is hosted as static files with no backend database or user tracking systems.
  • No Cookies: We do not use tracking cookies or analytics that could identify you.

Technical Data We May Collect

Like most websites, our hosting provider may automatically collect minimal technical information for security and performance purposes:

  • Your IP address (for security and abuse prevention)
  • Browser type and version (for compatibility)
  • Date and time of access (for performance monitoring)
  • Pages visited on our site (for analytics)

This technical data is anonymized, cannot be used to identify you personally, and is automatically deleted after a short period.

Third-Party Services

Hosting Provider

Our website is hosted by a reputable hosting provider. They may collect basic server logs as described above, but have no access to any data you process using our application.

No Analytics or Tracking

We deliberately choose not to use Google Analytics, Facebook Pixel, or other tracking services that could compromise your privacy.

Your Rights

Since we do not collect personal data, most data protection rights do not apply. However:

  • Right to Information: This privacy policy explains exactly how our service works.
  • Right to Control: You have complete control over what data you input and when.
  • Right to Delete: Simply close your browser tab - all processing data is automatically cleared.

Data Security

Since all processing happens on your device, your data security is primarily in your hands:

  • Keep your browser and device updated
  • Use our website over HTTPS (which we enforce)
  • Be cautious when using public or shared devices

Our website uses modern security headers and HTTPS encryption to protect your connection to our service.

Children's Privacy

Our service does not collect personal information from anyone, including children under 13. The privacy-first design makes it safe for users of all ages.

International Users

Since all processing happens in your browser, there are no international data transfers of your personal content. Our privacy-first approach complies with GDPR, CCPA, and other privacy regulations worldwide.

Changes to This Policy

We may update this privacy policy occasionally to reflect changes in our service or legal requirements. Any updates will be posted on this page with a new “Last updated” date.

Open Source

Our commitment to transparency extends to our code. You can review our source code to verify our privacy claims and see exactly how your data is processed.
