Quote from: PePinJeNek on January 02, 2013, 06:35 amI wish everyone a mindblowing 2013!!Just wanted to get some opinions about the usage of whatsapp for sensitive information.I have an android smartphone and use whatsapp to sometimes send text messages that if intercepted by LE could be harmfull for my safety.I'm not a noob but just wanted to find out if anyone can confirm that this service is safe to use and really encrypted all their traffic.I know that previous versions had safety issues and that people could hack your wifi and read all your messages, but apparently this issue is solved plus I never use wifi.For the people who don't know what it is, it is a messenger service for your mobile that uses mobile dataor wifi connection and it claims that their latest version fully encrypted all your messages.Any info or suggestions are welcome.PeaceTake a close look at their Terms of Service (TOS):  Log File Information: When you use the WhatsApp Site, our  servers automatically record certain information that your web  browser sends whenever you visit any website. These server logs  may include information such as your web request, Internet Protocol  ("IP") address, browser type, browser language, referring / exit  pages and URLs, platform type, number of clicks, domain names,  landing pages, pages viewed and the order of those pages, the  amount of time spent on particular pages, the date and time of  your request, one or more cookies that may uniquely identify your  browser, your phone number, phone number you are requesting the  status of and various status information. When you use the  WhatsApp Service, our servers log certain general information  that our application sends whenever a message is sent or received,  or if you update or request any status information, including time  and date stamps and the mobile phone numbers the messages were sent  from and to.   [...]  We may collect and release Personally Identifiable Information  and/or non-personally-identifiable information if required to do  so by law, or in the good-faith belief that such action is necessary  to comply with state and federal laws (such as U.S. Copyright Law),  international law or respond to a court order, subpoena, or search  warrant or equivalent, or where in our reasonable belief, an  individuals physical safety may be at risk or threatened. WhatsApp                                ^^^^^^^^ also reserves the right to disclose Personally Identifiable  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Information and/or non-personally-identifiable information that  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ WhatsApp believes, in good faith, is appropriate or necessary to  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ enforce our Terms of Service, take precautions against liability,  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ to investigate and defend itself against any third-party claims or  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^  allegations, to assist government enforcement agencies, to protect  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ the security or integrity of the WhatsApp Site or our servers, and  to protect the rights, property, or personal safety of WhatsApp, our  users or others.   So, in other words, they reserve the right to themselves to hand over your personal information to government agencies if, in their opinion, it is necessary or appropriate -- even in the absence of a warrant or other judicial process. Still feel good about them now?
