-Terms of Service
-
-This is the terms of service for the Android Backup Service.
-
-1. Your relationship with Google
-
-1.1 Your use of the Android Backup Service (referred to as the "Service" in this document) is subject to the terms of a legal agreement between you and Google. "Google" means Google LLC, whose principal place of business is at 1600 Amphitheatre Parkway, Mountain View, CA 94043, United States. This document explains how the agreement is made up, and sets out some of the terms of that agreement.
-
-1.2 Unless otherwise agreed in writing with Google, your agreement with Google will always include, at a minimum, the terms and conditions set out in this document. These are referred to below as the "Terms".
-
-1.3 The Terms form a legally binding agreement between you and Google in relation to your use of the Service. It is important that you take the time to read them carefully.
-
-2. Accepting the Terms
-
-2.1 In order to use the Service, you must first agree to the Terms. You may not use the Service if you do not accept the Terms.
-
-2.2 You can accept the Terms by clicking to accept or agree to the Terms, where this option is made available to you by Google.
-
-2.3 You may not use the Service and may not accept the Terms if you are not of legal age to form a binding contract with Google.
-
-2.4 You represent that you have full power, capacity and authority to accept these Terms. If you are accepting on behalf of your employer or another entity, you represent that you have full legal authority to bind your employer or such entity to these Terms. If you don't have the legal authority to bind, please ensure that an authorized person from your entity consents to and accepts these Terms.
-
-3. Provision of the Service by Google
-
-3.1 Google has subsidiaries and affiliated legal entities around the world ("Subsidiaries and Affiliates"). Sometimes, these companies will be providing the Service to you on behalf of Google itself. You acknowledge and agree that Subsidiaries and Affiliates will be entitled to provide the Service to you.
-
-3.2 Google is constantly innovating in order to provide the best possible experience for its users. You acknowledge and agree that the form and nature of the Service which Google provides may change from time to time without prior notice to you.
-
-3.3 As part of this continuing innovation, you acknowledge and agree that Google may stop (permanently or temporarily) providing the Service (or any features within the Service) to you or to users generally at Google's sole discretion, without prior notice to you. You may stop using the Service at any time. You do not need to specifically inform Google when you stop using the Service.
-
-3.4 You acknowledge and agree that if Google disables your Backup Service Key, you and the Android application(s) you developed ("Application(s)") may be prevented from accessing the Service and any content that is stored with the Service.
-
-3.5 You acknowledge and agree that Google may set a fixed upper limit on the number of backup transmissions you may send or receive through the Service or on the amount of storage space used for the provision of the Service at any time, at Google's discretion. You agree to abide by any such fixed upper limits.
-
-4. Use of the Service by you
-
-4.1 In order to access the Service, you must have a unique application identifier ("Package Name") for your Application as described in the documentation for the Service.
-
-4.2 After supplying Google with the Package Name and accepting the Terms, you will be issued an alphanumeric key ("Backup Service Key") assigned to you by Google that is uniquely associated with your Application. Your Application must include this Backup Service Key as described in the documentation for the Service.
-
-4.3 There is currently no limit to the number of Backup Service Keys you may obtain in this manner provided that you use a different Package Name for each Backup Service Key you obtain. You agree that each Backup Service Key is only valid for Applications with the corresponding Package Name. You agree that Google may, in its sole discretion, impose a limit on the number of Backup Service Keys that may be obtained in the future. You agree that your continued use of any of the Backup Service Keys assigned by Google, or distribution of any Applications using such Backup Service Keys, constitutes your continued agreement to these Terms.
-
-4.4 You agree to use the Service only for purposes that are permitted by (a) the Terms and (b) any applicable law, regulation, third-party terms of service, or generally accepted practices or guidelines in the relevant jurisdictions (including any laws regarding the export of data or software to and from the United States or other relevant countries).
-

-
-4.7 You agree that your use of the Service will be in compliance with any documentation guidelines provided by Google and that failure to comply with the documentation guidelines may result in the disabling of the Backup Service Key(s) for your Application(s).
-

-
-4.10 You agree that in your use of the Service, you and your Applications will protect the privacy and legal rights of users. You must provide legally adequate privacy notice and protection for users whose data your Applications back up to the Service. Further, your Application may only use that information for the limited purpose of backing up the data to the Service unless the user has given you permission for further use. If the user has not given you permission to back up information to the Service, you may not transmit such information to the Service.
-
-4.11 You agree that you and your Applications will not transmit or store sensitive user information, such as user names, passwords, or credit card numbers, through the Service.

You agree that you are solely responsible for (A) any Content that is transmitted through the Service by your Applications, and (B) any Content that Devices retrieve from the Service by virtue of your Applications. For purposes of the Terms, "Content" means information such as data, messages, settings information, written text, computer software, music, audio files or other sounds, photographs, videos or other images. "Device(s)" means device(s) powered by the Android operating system.
-
-7.2 You agree that you will not transmit any Content through the Service that is copyrighted, protected by trade secret or otherwise subject to third party proprietary rights, including patent, privacy and publicity rights, unless you are the owner of such rights or have permission from their rightful owner to transmit the Content through the Service.
-
-8. Proprietary rights
-
-8.1 You acknowledge and agree that Google (or Google's licensors) own all legal right, title and interest in and to the Service, including any intellectual property rights which subsist in the Service (whether those rights happen to be registered or not, and wherever in the world those rights may exist).
-
-8.2 Unless you have agreed otherwise in writing with Google, nothing in the Terms gives you a right to use any of Google's trade names, trademarks, service marks, logos, domain names, and other distinctive brand features.
-

These guidelines can be viewed online at http://www.google.com/permissions/ guidelines.html (or such other URL as Google may provide for this purpose from time to time).
-
-8.4 You agree that you shall not remove, obscure, or alter any proprietary rights notices (including copyright, trade mark notices) which may be affixed to or contained within the Service.
-

This license is for the sole purpose of enabling you to use and enjoy the benefit of the Service as provided by Google, in the manner permitted by the Terms.
-
-9.2 You may not (and you may not permit anyone else to) copy, modify, create a derivative work of, reverse engineer, decompile or otherwise attempt to extract the source code from the Service or any part thereof, unless this is expressly permitted or required by law, or unless you have been specifically told that you may do so by Google, in writing.
-
-9.3 Unless Google has given you specific written permission to do so, you may not assign (or grant a sub-license of) your rights to use the Service, grant a security interest in or over your rights to use the Service, or otherwise transfer any part of your rights to use the Service.
-
-10. Your code
-
-10.1 Google claims no ownership or control over any source code written by you to be used with the Service. You retain copyright and any other rights you already hold in this code, and you are responsible for protecting those rights, as appropriate.

-
-  (B) Google is required to do so by law (for example, where the provision of the Service to you is, or becomes, unlawful); or
-
-  (C) Google is transitioning to no longer providing the Service; or
-
-  (D) your Application fails to meet the documentation guidelines provided by Google.
-
-11.4 Nothing in this Section shall affect Google's rights regarding provision of the Service under Section 3 of the Terms.
-
-11.5 When these Terms come to an end, all of the legal rights, obligations and liabilities that you and Google have benefited from, been subject to (or which have accrued over time whilst the Terms have been in force) or which are expressed to continue indefinitely, shall be unaffected by this cessation, and the provisions of Sections 12, 13 and Paragraph 16 shall continue to apply to such rights, obligations and liabilities indefinitely.
-
-12. EXCLUSION OF WARRANTIES
-
-12.1 NOTHING IN THESE TERMS, INCLUDING SECTIONS 12 AND 13, SHALL EXCLUDE OR LIMIT GOOGLE'S WARRANTY OR LIABILITY FOR LOSSES WHICH MAY NOT BE LAWFULLY EXCLUDED OR LIMITED BY APPLICABLE LAW. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES OR CONDITIONS OR THE LIMITATION OR EXCLUSION OF LIABILITY FOR LOSS OR DAMAGE CAUSED BY NEGLIGENCE, BREACH OF CONTRACT OR BREACH OF IMPLIED TERMS, OR INCIDENTAL OR CONSEQUENTIAL DAMAGES.

-## 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!

+## What is KeePass DX?
+
+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.
+
+KeePass DX 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, KeePass DX 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 features may not be available to incentivize the contribution to the work of open source projects. These optional visuals are accessible after a donation (and a small 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.*
