+## What is KeePassDX?
+
+An alternative to remembering an endless list of passwords manually. This is made more difficult by **using different passwords for each account**. If you use one password everywhere and security fails only one of those places, it grants access to your e-mail account, website, etc, and you may not know about it or notice, before bad things happen.
+
+KeePassDX is a **password manager for Android**, which helps you **manage your passwords in a secure way**. You can put all your passwords in one database, locked with a **master key** and/or a **keyfile**. You **only have to remember one single master password and/or select the keyfile** to unlock the whole database. The databases are encrypted using the best and **most secure encryption algorithms** currently known.
+
+## Small print?
+
+KeePassDX is under **open source GPL3 license**, meaning you can use, study, change and share it at will. Copyleft ensures it stays that way.
+From the full source, anyone can build, fork, and check whether for example the encryption algorithms are implemented correctly.
+There is **no advertising**.
+
+Do not worry, **the main features remain completely free**.
+
+Optional visual styles are accessible after a contribution (and a congratulatory message (Ո‿Ո) ) or the purchase of an extended version to encourage contribution to the work of open source projects!
+*If you contribute to the project and do not have access to the styles, do not hesitate to contact the author at [contact@kunzisoft.com](contact@kunzisoft.com).*

-## What is KeePassDX?
-
-Today you need to remember many passwords. You need a password for your e-mail account, your website's FTP password, online passwords (like website member account), etc. etc. etc. The list is endless. Also, you **should use different passwords for each account**. Because if you use only one password everywhere and someone gets this password you have a problem... A serious problem. The thief would have access to your e-mail account, website, etc. Unimaginable.
-
-KeePassDX is a **free open source password manager for Android**, which helps you to **manage your passwords in a secure way**. You can put all your passwords in one database, which is locked with one **master key** or a **key file**. So you **only have to remember one single master password or select the key file** to unlock the whole database. The databases are encrypted using the best and **most secure encryption algorithms** currently known.
-
-## Is it really free?
-
-Yes, KeePassDX is under **free license (OSI certified)** and **without advertising**. You can have a look at its full source and check whether the encryption algorithms are implemented correctly.
-
-*Note : If you access the application from a store, visual styles may not be available to encourage contribution to the work of open source projects. These optional styles are accessible after a contribution (and a congratulation message :) or the purchase of an extended version, but do not worry, the main features remain completely free. If you contribute to the project and you do not have access to the themes, do not hesitate to contact me at [contact@kunzisoft.com](contact@kunzisoft.com), I will give you the procedure.*
