Iranian state television on Tuesday afternoon urged the country’s public to remove the messaging platform WhatsApp from their smartphones, alleging the app — without offering specific evidence — gathered user information to send to Israel.

In a statement, WhatsApp said it was “concerned these false reports will be an excuse for our services to be blocked at a time when people need them the most.” WhatsApp uses end-to-end encryption, meaning a service provider in the middle can’t read a message.

“We do not track your precise location, we don’t keep logs of who everyone is messaging and we do not track the personal messages people are sending one another,” it added. “We do not provide bulk information to any government.”

End-to-end encryption means that messages are scrambled so that only the sender and recipient can see them. If anyone else intercepts the message, all they will see is a garble that can’t be unscrambled without the key.

Gregory Falco, an assistant professor of engineering at Cornell University and cybersecurity expert, said it’s been demonstrated that it’s possible to understand metadata about WhatsApp that does not get encrypted.
