  Also WhatsApp privacy policy: As part of the Meta Companies, WhatsApp receives information from, and shares information (see here) with, the other Meta Companies. We may use the information we receive from them, and they may use the information we share with them, to help operate, provide, improve, understand, customize, support, and market our Services and their offerings, including the Meta Company Products. This includes: - improving their services and your experiences using them, such as making suggestions for you (for example, of friends or group connections, or of interesting content), personalizing features and content, helping you complete purchases and transactions, and showing relevant offers and ads across the Meta Company Products ==== Popular theory is they can't see or store your messages, but can analyze them on the client and profile you (e.g. interested in brazil nuts)

  Meta controls the proprietary Whatsapp client software that decrypts your messages and they can have that decrypt and scan the messages for them and send back metrics and how often different words are used. They can of course also have their app de-crypt and re-encrypt the messages to the key of a requesting third party like police or hired reviewers if certain keywords are used. Authorities could also have Google or Apple ship a signed tampered Whatsapp binary to any user or group of users, like protestors, that uses a custom seeded random number generator so they can predict all encryption keys generated and no one else, including Meta, will know. The variant of end to end encryption where third parties control the proprietary software on both ends, is called marketing.

  It's possible that the client blindly fetches a mapping from keyword to ads, saw the keyword client-side, then requested the ad.
  • Drakim 4y ago
    You'd indirectly reveal what those keywords are to Meta by which ads are being requested. If an ad for a sex toy is being requested, it's pretty obvious what the two parties are talking about.

    Still information leaks the encrypted channel and the trust is broken.

  > WhatsApp privacy policy Facebook has a deep culture of pathological lying. They lied to the FTC [1]. They lied to WhatsApp and to the EU [2]. They created an Oversight Board and then lied to it [3]. Each of those lies are more substantial than lying in a privacy policy.

    saying someone lied in the past is not convincing evidence that any arbitrary statement by them is affirmatively a lie

  What does “conversation “ mean in that text. I can perfectly mean just the audio exchanges when both parties talk. Also: E2E does not imply necessarily that they do not know the key.

  I hate to break it to you, but a privacy policy is not a legally binding document.

  Prove it. Open source the client and open the server for 3rd party apps to use.
