Our data is encrypted in transit and at rest. Data received is encrypted in transit using https, SSL/TLS, and DTLS 1.3/SRTP. Data is encrypted at rest with AES256.
All persistent data is encrypted at rest according to the policies of Google Cloud Firestore and Google Cloud Storage. Chat and calling is encrypted in transit, and all stored data is encrypted at rest. This is the norm for video calling software and is equivalent to the security of Google Meet, for example.
