Your attendees have real reasons for privacy
If you're running any kind of 18+ event, your attendees are trusting you with sensitive information. Their name, email address, and the fact that they attended your event are all things they may not want anyone else to know about.
On a commercial ticketing platform, that data sits in plain text on someone else's servers. Platform staff and contractors can access it. A data breach would expose not just names and emails but a record of which events each person attended.
Chobble Tickets encrypts all personally identifiable information at rest using hybrid RSA-OAEP + AES-256-GCM encryption. Even if someone gained access to the database, they could not read attendee names or contact details without your private key.
