+    Son from SimpleLogin here. I hope you are doing well and are staying at home in this difficult time. By the way I'm writing this newsletter from my couch with my cats proofreading the text :). <br>

+    1) <b>Mobile apps</b> <br><br>
+
+    <img src="https://simplelogin.io/blog/devices.png" style="max-width: 100%"> <br><br>
+
+    Now you can quickly create aliases on-the-go with SimpleLogin Android and iOS app,
+    thanks to our mobile guy Thanh-Nhon! <br>
+
+    Download the Android app on
+    <a href="https://play.google.com/store/apps/details?id=io.simplelogin.android">Play Store</a> and the iOS app on
+    <a href="https://apps.apple.com/us/app/simplelogin-anti-spam/id1494359858">App Store</a>. <br>
+
+    With the release of the mobile apps, SimpleLogin now covers most major platforms: <br>
+
+    - Desktop with SimpleLogin web app or Chrome, Firefox and Safari extension <br>
+    - Mobile with Android and iOS app <br>
+
+    The code is of course open-source and available on our <a href="http://github.com/simple-login/">Github</a>
+
+  {% endcall %}

+  {% call text() %}
+    2) <b>Dark mode</b> <br><br>
+
+    <img src="https://simplelogin.io/blog/dark-mode.gif" style="width: 100%"> <br><br>
+
+    You have asked for it and now the dark mode is finally available, kudos to Dung - our full-stack guy. <br>
+    You can finally enjoy using SimpleLogin in the dark.
+  {% endcall %}
+
+  {% call text() %}
+    3) <b>Alias name, new UI, security page, new policy privacy</b> <br><br>
+
+    <img src="https://simplelogin.io/blog/new-ui.gif" style="width: 100%"> <br><br>
+
+    You might have noticed that the web UI is now more compact: the web app has undergone a remake
+    to make it more responsive for usual actions like enabling/disabling an alias, updating alias note, etc. <br>
+
+    You can set a name for your alias too: this name is used when you send emails or reply from your alias.<br>
+
+    We have also created a new <a href="https://simplelogin.io/security/">security page</a> that goes into the technical details of SimpleLogin.
+    Our <a href="https://simplelogin.io/privacy/">privacy page</a> is also rewritten from scratch: nothing changes about your data protection
+    but the page is more clear and detailed now.
+
+  {% endcall %}
+
+  {% call text() %}
+    4) <b>Facebook, Google, Github login deprecation</b> <br>
+    We have decided to deprecate those social login options because of several reasons: <br>
+
+    - Privacy: every time you sign in using one of these methods, the respective company knows and
+    we have no information on what they do with this data. <br>
+    - Not fully open-standard compatible: these platforms enjoy their monopolies and
+    don't play well with open standards like OAuth2/OpenID: in fact, implementations on mobile of these social login
+    require their SDK that we refuse to add because of privacy concern. <br>
+    - Uniform experiences for all users: to have these social login in our iOS app, we need to support "Sign in with
+    Apple" that isn't broadly available for Android users.
+    Again, another big tech enjoying its monopoly. <br>
+
+    If you happen to use one of these social login options, please create a password for your account on the
+    <a href="https://app.simplelogin.io/dashboard/setting">Setting page</a> <br>
+
+    You can still sign in using these social login until 2020-05-31. After this date, they will be removed.
