Signal proti WhatsAppu: kateri Messenger dejansko ohranja vaše klepete zasebne?

24. junij 2026 · 2 min branja · Komentarji

Obe aplikaciji pravita, da uporabljata šifriranje od konca do konca. Toda šifriranje je le del zgodbe. Tukaj je tisto, kar ju pravzaprav ločuje.

Kaj pravzaprav pomeni šifriranje od konca do konca

End-to-end encryption means only you and the person you're messaging can read the contents of your messages. Not the app company, not your mobile carrier, not the government — unless they get into your actual phone.
Both Signal and WhatsApp use end-to-end encryption for message content. On this point, they are equal. The difference is everything else.

Even if WhatsApp can't read your messages, it can — and does — collect metadata: who you talk to, how often, at what times, your location, your device, your contacts list.
Meta (WhatsApp's parent company) uses this data to build advertising profiles and shares it across Instagram and Facebook.
Signal collects almost none of this. The only data Signal holds about you is your phone number and the date you last connected.

Signal's code is open source — anyone can read it, audit it, and verify it does what it claims. Security researchers around the world have done exactly this.
WhatsApp's code is closed. You have to take Meta's word for it that the encryption is correctly implemented and that no backdoors exist. Given Meta's track record with user data, that's a lot of trust.

The only real drawback: your contacts need to have Signal too. You can't send a Signal message to a WhatsApp user.
Signal has grown significantly — it now has over 100 million users. Many people already have it.
The practical approach: keep WhatsApp for group chats with family who won't switch, move sensitive conversations to Signal.

Signal Advantage: — z veliko razliko, če vam je zasebnost pomembna.
