Privacy Policy

This page describes what information the iiibd.com website collects and how it is used. The document is informational and is maintained by the project team.

What data we collect

• Account: email and password (hash), so you can sign in to your personal account.
• Profile data: name, avatar, lesson progress and saved patches — only what you enter yourself.
• Analytics: anonymized visit statistics (Yandex.Metrica), including pages, sources and device.
• Requests and forms: contact details you submit through forms (name, email, phone, message).

How we use the data

• To run the personal account and save progress.
• To respond to your requests and feedback.
• To improve the site and the content (aggregated analytics).
• For security — detecting attacks, bots and abuse.

Sharing with third parties

We do not sell personal data. Technical contractors (hosting, analytics, AI providers) process data only to the extent required to run the service.

Cookies
