We never store, log, or track any phone numbers or messages you enter. Everything happens securely inside your own web browser, ensuring complete data sovereignty.

This means your message is sent through WhatsApp's own secure infrastructure. OPN Chat simply provides a convenient interface — we never intercept, read, or store your messages. It's the same as typing a wa.me link manually, but faster and easier.
