DELE.TO - Alternative to OneTimeSecret

Comparing client-side vs server-side encryption approaches. Both are popular, but they handle your data very differently.

Critical Security Difference

DELE.TO encrypts your data in your browser before sending it anywhere (zero-knowledge). OneTimeSecret receives your plaintext data and encrypts it on their servers. This is a fundamental architectural difference that affects your privacy and security.

DELE.TO
