-# F.A.Q.
-
-## Why KeePass DX?
-
-KeePass DX is an **Android password manager** implemented from Keepass password manager.
-
-KeePass DX was created to meet the security and usability needs of a KeePass application on Android :
-
- - To be easy to use with **secure password management and form filling tools**.
- - To use only tools under **open source license** to guarantee the security of the application (With [open source store](https://f-droid.org/en/) and no closed API).
- - To be in a **native langage** (java) for weight, security and a better integration of the application.
- - To respect **Android design, architecture and ergonomic**.
-
-## What makes KeePass DX stand out from other password managers?
-
- - We **do not recover your sensitive data** on a private server or a closed cloud, you have control of your passwords.
- - We respect **KeePass file standards** to maintain compatibility and data porting on different devices (computers and portable devices with different operating system).
- - The code is **open source**, which implies increased **security**, you can check how the encryption algorithms are implemented.
- - We remain attentive to **your needs** and we can even integrate the features that you have defined.
- - We **do not put advertising** even in the free version.
-
-## How am I sure my passwords are safely stored on the application?
-
-- We allow users to save and use passwords, keys and digital identities in a secure way by **integrating the last encryption algorithms** and **Android architecture standards**.
-- You can increase the security of your database by increasing the rounds of encryption keys. *(In Settings -> Database Settings when your database is open)* **Warning**: *Increase the number of rounds sparingly to have a reasonable opening time.*
-
-## Can I store my data on a cloud storage?
-
-**Yes** this is possible. Otherwise, we **recommend using cloud with personal server and open source license**, like [NextCloud](https://f-droid.org/en/packages/com.nextcloud.client/) to be sure how your databases are stored.
-
-## Can I recover my passwords on another device if I loose my main device?
-
-**Yes** you can, but you **must first save the .kdb or .kdbx file from your database to an external storage** *(like a hardrive or a cloud)*.
-We recommend you save your data after each modification so incase you loose your android device you could retrieve the data and import it into the new KeePass DX installed on the new android device. 
-
-## Why are updates not available at the same time on all stores?
-
-- **PlayStore** only needs an APK generated and manually signed to be available on the store, it usually takes **20 minutes** to be available because it is deployed with fastlane. But the management of the APK and its data by the google servers is obscure.
-- **F-Droid**, to **ensure that the code is open source**, checks the sources directly on git repository (by checking the presence of new tags) and builds itself the APK that the server signs during the compilation of code and dependencies. Updating the project will take **1-10 days** for F-Droid to analyze all available repositories, build sources and deploy the generated APK. So F-Droid is slower for deployment but it is run by **volunteers** and guaranteed a **clean APK**. :)
-
-## Why not an online version?
-
-The offline and online client concepts only exists with Keepass2Android because the file access network tools are directly integrated into the code of the main application. Which is a very dubious choice knowing that **it is not normally the purpose of a password management application to take care of external file synchronization on clouds** (which can be under closed licensed and recover your data base), it is rather the purpose of the [file management application](https://developer.android.com/guide/topics/providers/document-provider).
-
-## Can I open my database easily other than with a password?
-
-**Yes**, we have integrated a secure openning option of fingerprint for android devices that support this feature, so no one can access the application without scanning his/her fingerprint or fill a master key.
-
-## Can I open my database without my master key (master password and/or key file)?
-
-**No**, you can not open a database file without the master password (and / or) the associated key file. Be sure to remember your master password and save the key file in a safe place.
-
-## Can I suggest features and report bugs for the application?
-**Yes**, we welcome this you could go ahead and do that on our github:

+-----------------------------------------------------------
+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide
+development of collaborative font projects, to support the font creation
+efforts of academic and linguistic communities, and to provide a free and
+open framework in which fonts may be shared and improved in partnership
+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded, 
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.
+
+DEFINITIONS
+"Font Software" refers to the set of files released by the Copyright
+Holder(s) under this license and clearly marked as such. This may
+include source files, build scripts and documentation.
+
+"Reserved Font Name" refers to any names specified as such after the
+copyright statement(s).
+
+"Original Version" refers to the collection of Font Software components as
+distributed by the Copyright Holder(s).
+
+"Modified Version" refers to any derivative made by adding to, deleting,
+or substituting -- in part or in whole -- any of the components of the
+Original Version, by changing formats or by porting the Font Software to a
+new environment.
+

+writer or other person who contributed to the Font Software.
+
+PERMISSION & CONDITIONS
+Permission is hereby granted, free of charge, to any person obtaining
+a copy of the Font Software, to use, study, copy, merge, embed, modify,
+redistribute, and sell modified and unmodified copies of the Font
+Software, subject to the following conditions:
+
+1) Neither the Font Software nor any of its individual components,
+in Original or Modified Versions, may be sold by itself.
+
+2) Original or Modified Versions of the Font Software may be bundled,
+redistributed and/or sold with any software, provided that each copy
+contains the above copyright notice and this license. These can be
+included either as stand-alone text files, human-readable headers or
+in the appropriate machine-readable metadata fields within text or
+binary files as long as those fields can be easily viewed by the user.
+
+3) No Modified Version of the Font Software may use the Reserved Font
+Name(s) unless explicit written permission is granted by the corresponding
+Copyright Holder. This restriction only applies to the primary font name as
+presented to the users.
+
+4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
+Software shall not be used to promote, endorse or advertise any
+Modified Version, except to acknowledge the contribution(s) of the
+Copyright Holder(s) and the Author(s) or with their explicit written
+permission.
+
+5) The Font Software, modified or unmodified, in part or in whole,
+must be distributed entirely under this license, and must not be
