6 Cookies & Tracking Technologies

399der's website and app use cookies and similar tracking technologies. These help improve your browsing experience and ensure the security of the platform.

Cookie Types:

• Essential Cookies: Required to maintain login sessions and ensure security — these cannot be disabled.
• Functional Cookies: To remember your language preference, theme, and other settings.
• Analytics Cookies: To understand which pages are used most — data is fully anonymized.
• Security Cookies: To detect bot activity and fraudulent login attempts.

You can delete or disable cookies at any time through your browser settings. However, disabling essential cookies may cause some platform features to not function properly.

7 Security Measures

399der uses industry-leading security technology to protect your data. Our security team monitors the platform around the clock, 24 hours a day.

• SSL/TLS Encryption: 256-bit SSL encryption is applied to all data transmissions.
• Two-Factor Authentication (2FA): Additional OTP verification at login.
• Data Encryption: All stored sensitive data is protected with AES-256 encryption.

• Regular Security Audits: Regular audits conducted by third-party security experts.
• Staff Training: Only authorized personnel can access data on a need-to-know basis.

In the event of a security incident, we will promptly notify affected users and take the necessary steps. That said, no system on the internet is 100% secure, so keeping your password private and avoiding unfamiliar links is equally important.
