If anyone who has access to your phone or PIN can see your profile, or if the app can be opened without any additional code, your <span style=\"font-weight: bold\" class=\"Apple-style-span\">data<\/span> is at risk.

One of them is knowing whether or not the message has been received; a question like &#8220;h<span style=\"font-weight: bold\" class=\"Apple-style-span\">as she read it?<\/span>&#8221;&nbsp;can bother us more than the possibility of a hacker.<\/p>\n<p>We considered the security and privacy features that users value the most when sending messages, and these are the <span style=\"font-weight: bold\" class=\"Apple-style-span\">parameters<\/span> we finally chose for comparison:<\/p>\n<ul>\n<li><span style=\"font-weight: bold\" class=\"Apple-style-span\">Delivery icons:<\/span> Does the app tell you if the message has been read or copied?

If you can\u2019t, you\u2019ll appear in contact lists without knowing it.<\/li>\n<li><span style=\"font-weight: bold\" class=\"Apple-style-span\">Prevent unauthorized access:<\/span> For convenience, many people don\u2019t block their phone, but that means anyone can access their messages. Can the app be locked individually?<\/li>\n<li><span style=\"font-weight: bold\" class=\"Apple-style-span\">Downloading multimedia files:<\/span> Unsolicited files could be a risk to the safety and privacy of others (and can get you into trouble). Can the automatic downloads be disabled?<\/li>\n<li><span style=\"font-weight: bold\" class=\"Apple-style-span\">Self-destruction and secret chats:<\/span> Does the app have a powerful encryption system and are messages self-destructing? Is it reliable?<\/li>\n<li><span style=\"font-weight: bold\" class=\"Apple-style-span\">Block unknown users:<\/span> Can you stop people who aren&#8217;t in your phone book from contacting you? Does it have a generic filter for unknown users, in addition to your contacts?<\/li>\n<li><span style=\"font-weight: bold\" class=\"Apple-style-span\">Hide notifications:<\/span> Can you hide message notifications completely to maintain secrecy?
