Questions & Answers

Frequently AskedQuestions

Find answers to common questions about Antachat's security, privacy, and features.

Yes. Our end-to-end encryption means that only you and your conversation partner(s) can read messages. We cannot decrypt your content on our servers, and we do not store your encryption keys.

PQC refers to cryptographic algorithms that are resistant to the theoretical threat posed by large-scale quantum computers. We use a hybrid approach, combining classical ECDH with modern ML-KEM (Kyber) to provide robust security for both today and the future.

We are designed to collect virtually no metadata. We do not know who you are talking to, when, or for how long. The only data we store is the time your account was created and the last time you connected to the service.
