    Signal works the same but without the user tracking from Meta/Facebook. Many people use it as well but I'm surprised that a majority sticks to WhatsApp. Source: 5 months ago
  • A Practical Guide For Safety And Reporting Crimes For Our Community
    A question I often get is "Well are my text messages safe" The short answer is... Maybe? Depends on what type of phone you use, your carrier, and a bunch of other factors. One way to avoid this is to use an end-to-end encrypted text service like Signal if that is a concern of yours. VERY IMPORTANT NOTES: Telegram and WhatsApp are not secure. The way to think of this security is that if is retained by a server... Source: 5 months ago

    The linked page is on signalusers.org, but Signal's regular home site is https://signal.org/. I'm looking all over signal.org for some link from there to signalusers.org, as that would make me more relaxed about the authenticity of the latter -- i.e., that it really is run by the same people who run signal.org. Yes, maybe I'm being paranoid. But we're talking about an app whose whole purpose is secure... - Source: Hacker News / 6 months ago

    WhatsApp and Signal: Of course I’m going to conclude with the point to point encrypted communication apps Signal and WhatsApp. Most of our clients around the world communicate in these apps more than they make phone calls or send emails. Set up an account in each app and start leveraging the text, photo, phone and video features to have easy and fast conversations with your global contacts. See https://signal.org...

  • us What's a good (under $500, preferably lower than $200 though) android for geeks?
    Ironically, Pixels are the best for de-Googling. GrapheneOS requires a Pixel, as does CalyxOS for the most part. If you don't want your money going to Google, a used/refurb Pixel gets around that in my opinion. Source: 10 months ago
