  • Does NOT collect personal data
  • Covered in Sections 4-14

  • Uses Google Analytics cookies
  • Collects anonymous usage statistics
  • Covered in Section 3

3. WEBSITE ANALYTICS (vi-voice.com)

This section applies ONLY to our website vi-voice.com, NOT to the Vi Voice extension.

Our website uses Google Analytics and Google Tag Manager to understand how visitors use our site. This helps us improve the website experience.

What Google Analytics collects:

  • Pages you visit on vi-voice.com
  • Time spent on each page
  • Your browser type and language
  • Country/region (based on IP address)
  • How you arrived at our site (referrer)

Cookies used on the website:

  • _ga - main Google Analytics cookie (expires: 2 years)
  • _gid - distinguishes users (expires: 24 hours)
  • _gat - throttles request rate (expires: 1 minute)
  • cookiescript_accept - your consent preferences (expires: 1 year)

Legal basis: Legitimate interest (GDPR Art. 6.1.f) - we need to understand website usage to improve our service. You can opt-out via the Cookie Settings button below.

Data sharing: Analytics data is processed by Google LLC (USA). Google's Privacy Policy applies: https://policies.google.com/privacy

Your control: You can manage your cookie preferences using the "Manage Cookie Settings" button in Section 15 below.

IMPORTANT: Google Analytics cookies are ONLY on the website vi-voice.com. The Vi Voice extension itself does NOT use any cookies or tracking.

4. WHAT DATA THE EXTENSION COLLECTS

This section describes data collected by the Vi Voice extension, NOT the website.

We collect the minimum amount of data necessary for the extension to function:

Device ID - a unique pseudonymized device identifier

  • Generated randomly in your browser
  • Required to authorize your requests
  • Not linked to your identity
  • Legal basis: legitimate interest (GDPR Art. 6.1.f) - the service cannot function without it

Encrypted OpenAI API key (stored encrypted with AES-256-GCM)

  • Associated with device_id for your authorization
  • We cannot decrypt it without your master_secret

Usage statistics:

  • Number of service requests
  • Request processing time
  • GPT model used (gpt-3.5-turbo, gpt-4o-mini, gpt-4o)
  • Dictation language
  • Number of processed tokens

5. WHAT DATA THE EXTENSION DOES NOT COLLECT

This section describes what the Vi Voice extension does NOT collect.

The extension does NOT collect or store:

  • Personal data (name, email, phone, address)
  • Texts you dictate
  • IP addresses
  • Your browsing history
  • Information about your computer or browser

6. DATA AGGREGATION AND MINIMIZATION

We apply the principle of data minimization to protect your privacy and comply with GDPR. This means we transform detailed information into anonymous statistics, making it impossible to track specific users.

HOW IT WORKS:

  • Every hour: detailed logs become aggregated statistics
  • After aggregation we know "there were 50 users", but not who they are
  • After 90 days: all records with device identifiers are completely deleted

RESULT:
After data processing it is impossible to:

  • Track specific device activity
  • Restore usage history
  • Link statistics to a specific user

We retain only anonymous metrics to improve the service: total number of users, average response time, popular languages. This data contains no information about specific devices or users.

7. HOW WE USE DATA

Collected data is used exclusively for:

  • Providing text processing service
  • Protection against abuse (rate limiting)
  • Improving service quality
  • Creating anonymous usage statistics

8. DATA SECURITY

We apply modern protection methods:

  • API key encryption: AES-256-GCM
  • Text encryption during transmission: XOR with one-time key
  • Secure connection: HTTPS/TLS
  • "Zero knowledge" principle: we cannot decrypt your API keys without your master_secret
  • Dictation texts exist only in server RAM for 2-3 seconds during processing

9. DATA RETENTION PERIODS

  • Detailed logs with device_hash: automatic deletion after 90 days
  • Encrypted API keys: stored until manually deleted by user
  • Aggregated statistics: indefinitely (completely anonymous)
  • Dictation texts: not stored at all

10. DATA SHARING WITH THIRD PARTIES

We share data only with:

  • OpenAI - for text processing through their API (their Privacy Policy applies)
  • Google LLC - website analytics through Google Analytics and Google Tag Manager (only for vi-voice.com website visitors, not extension users). Google Privacy Policy applies: https://policies.google.com/privacy
  • We DO NOT sell, rent, or share your data with other companies

11. YOUR RIGHTS (GDPR)

Under the General Data Protection Regulation (GDPR), you have the right to:

  • ACCESS - request what data we store about you
  • CORRECTION - correct inaccurate data
  • DELETION - when deleting API key through the extension:
    • Immediately deleted: device_id and encrypted API key
    • Within 90 days deleted: all request history (device_hash)
    • After complete deletion it is impossible to restore or link data to your device
  • RESTRICTION - restrict processing of your data
  • PORTABILITY - receive your data in machine-readable format
  • OBJECTION - object to data processing

To exercise these rights, contact us:

12. CHILDREN'S DATA

Our service is not intended for persons under 16 years of age. We do not knowingly collect children's data. If you believe we have accidentally collected a child's data, please contact us.

13. INTERNATIONAL DATA TRANSFER

Your data is processed on servers in the USA (through OpenAI API). By using the service, you agree to such data transfer.

14. CHANGES TO POLICY

We may update this policy. We will notify you of significant changes through the extension. The date of the last update is indicated at the top of the document.
