Privacy Policy

Account Data

When you register, we collect your name, email address, and (if available) profile photo. When signing in via Google or GitHub, this data is provided by the respective provider.

Progress Data

We store information about completed lessons, earned XP, current level and streak — to show your learning progress.

Technical Data

Standard technical data: IP address (to prevent abuse), browser type, pages viewed. This data is not linked to a specific user and is deleted automatically.

Service Provision

Data is used exclusively to operate the platform: authentication, saving progress, personalizing learning.

Security

IP addresses and request counters are used to protect against brute-force attacks and spam. We never sell or share this data with third parties.

Analytics

We use Cloudflare Web Analytics — anonymous visit statistics collection without cookies and without storing personal data.

Where data is stored

Data is stored on secure servers. Passwords are never stored in plain text — only as a hash (bcrypt).

Sessions

Authorization sessions are stored as encrypted JWT tokens. Session validity — 30 days.

HTTPS

All traffic between browser and server is protected by HTTPS with HSTS.

Google / GitHub OAuth

If you sign in via Google or GitHub, we only receive the public profile (name, email, photo). We do not access your repositories, emails or other private data.

Cloudflare

The site is protected and accelerated by Cloudflare. Cloudflare may process network requests according to its own privacy policy.

AI Assistant

Requests to the AI assistant may be processed by an external AI provider. Do not share personal or confidential information in the chat.

Data Access

You have the right to request a copy of your personal data stored on the platform.

Account Deletion

You can delete your account and all associated data at any time. Data is fully deleted within 30 days.

Correction

You can change your name and other profile data in your account settings.

Session cookies

We only use technically necessary cookies to maintain the authorization session. No advertising or tracking cookies.

Theme settings

Theme choice (dark/light) is stored in the browser's localStorage — locally, without being sent to the server.

We may update this policy. We will notify you of significant changes through the platform. By continuing to use the service after an update, you accept the new terms.
