FAQ

1. What is the difference between TLS and end-to-end encryption in scheduling applications?

Transport Layer Security (TLS) encrypts data during transmission between the user’s browser and the scheduling server, protecting against interception during transit. However, the data is decrypted at the server, making it accessible to the service provider. End-to-end encryption (E2EE), on the other hand, encrypts messages on the sender’s device and only decrypts them on the recipient’s device, ensuring that even the scheduling service provider cannot access the content. This provides a higher level of privacy for sensitive scheduling communications but can make certain server-side features more challenging to implement.

2. How does message encryption affect scheduling app performance?

Encryption operations require computational resources, which can impact performance, especially on mobile devices or older browsers. The performance impact depends on several factors, including the encryption algorithms used, the volume of data being encrypted, and the device’s processing power.
