• No ads, no tracking, and no data sharing: We protect your privacy.
• Zero-knowledge architecture: Entire events, including event notifications, are encrypted and hidden from our servers. We do not know when your meetings are taking place, who they are with, or what they are about.
• Based in Germany: All data is safeguarded by strict German data protection laws.
• Fully GDPR-compliant
FULLY FEATURED
