Privacy Policy

Last updated: January 2026

The Short Version

MaskContext processes all text locally in your browser. We don't collect, store, or transmit your text content. Your data never leaves your device.

1. Data Controller

The data controller for this website is:

Milestone One
contact@milestone-one.com

2. Data We Don't Collect

MaskContext is designed with privacy as the core principle. We explicitly do NOT collect:

  • Your text content - All text processing happens locally in your browser
  • Personal identifiers - We don't require registration or login
  • Usage data - We don't track what you anonymize
  • Cookies for tracking - We don't use tracking cookies

3. How the Service Works

MaskContext uses AI models that are downloaded to and run entirely within your web browser:

  • AI models are loaded once and cached in your browser
  • Text processing happens on your device using WebAssembly
  • No text is transmitted to our servers or any third party
  • The service works even when you're offline

4. Technical Data

Our web hosting provider may collect basic technical data for security and performance purposes, such as:

  • IP address (anonymized)
  • Browser type
  • Access timestamps

This data is used solely for security monitoring and is not linked to any personal information or your usage of the anonymization features.

5. Third-Party Services

MaskContext loads AI models from Hugging Face's content delivery network. This is a one-time download that is cached in your browser. The models themselves do not transmit any of your text content.

6. Your Rights Under GDPR

As a resident of the European Union, you have rights under the General Data Protection Regulation (GDPR). However, since we don't collect personal data, most of these rights don't apply in practice:

  • Right of Access - We don't store your data, so there's nothing to access
  • Right to Erasure - No data to erase
  • Right to Rectification - No data to correct
  • Right to Data Portability - No data to transfer

If you have any questions or concerns about your privacy, you can contact us at contact@milestone-one.com.

7. Children's Privacy

Our Service is not directed to children under 16. We do not knowingly collect any information from anyone, including children.

8. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by updating the "Last updated" date. Your continued use of the Service after changes constitutes acceptance of the new policy.
