1. Data Controller

HighLoad.Fun ("we", "us", "our") is responsible for the processing of your personal data. For privacy-related inquiries, contact us at privacy@highload.fun.

2. Data We Collect

Data from GitHub OAuth

When you sign in via GitHub, we receive and store:

• GitHub user ID, login, full name, email address
• Avatar URL, company, location

Data You Provide

• Profile description and links
• Source code submissions
• Discussion comments and articles

Platform-Generated Data

• Reputation points (RP) and activity log
• Solution submissions, scores, and execution metrics
• Timestamps (registration, last seen, submissions)

3. Legal Basis

We process your data based on:

• Contract performance — to provide the platform services you signed up for
• Legitimate interest — to maintain platform integrity, prevent abuse, and improve our services
• Consent — for non-essential cookies (analytics and marketing)

4. Cookies

Essential Cookies

These are required for the platform to function and cannot be disabled:

• Session cookie — maintains your authenticated session
• OAuth CSRF token — protects the login flow
• Cookie consent — remembers your cookie preference

Marketing & Analytics Cookies

With your explicit consent, we may load:

• Google Ads — for advertising and conversion tracking
• Google Analytics — for traffic and behavior analytics
• Facebook (Meta) Pixel — for advertising and analytics

You can manage your cookie preferences at any time using the "Cookie Settings" link in the footer.

Google AdSense loads on every page. Without your "Accept All" consent, AdSense runs in non-personalized mode (no interest-based targeting cookies); after consent it switches to personalized ads on subsequent navigation.

Google Analytics also loads on every page, but uses Google Consent Mode v2: without your consent it runs in cookieless mode (no identifiers, no tracking cookies, only aggregated pings); after "Accept All" it switches to full analytics with identifiers for the current session.

5. Your Rights

Under GDPR and applicable data protection laws, you have the right to:

• Access — obtain a copy of your personal data
• Rectification — correct inaccurate data (update your GitHub profile; changes sync on next login)
• Erasure — delete your account and associated personal data
• Portability — export your data in a machine-readable format

Sign in to exercise your access, portability, and erasure rights.

6. Third Parties

• GitHub — OAuth authentication provider
• Google Ads — advertising (only with consent)
• Google Analytics — traffic analytics (only with consent)
• Facebook (Meta) — pixel analytics (only with consent)

7. Data Retention

We retain your personal data for as long as your account is active. When you delete your account, your personal data is anonymized. Submitted solutions remain on the platform under an anonymized profile ("[deleted]") for leaderboard integrity.
