+
+3. Provision of the Service by Google
+

+
+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.

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).

+
+4.10 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.
+
+8.3 If you have been given an explicit right to use any of these brand features in a separate written agreement with Google, then you agree that your use of such features shall be in compliance with that agreement, any applicable provisions of the Terms, and Google's brand feature use guidelines as updated from time to time. 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.
+
+9. License from Google
+
+9.1 Subject to terms and conditions of these Terms, Google gives you a personal, worldwide, royalty-free, non-assignable and non-exclusive license to use the Service as provided to you by Google. 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. ACCORDINGLY, ONLY THE LIMITATIONS WHICH ARE LAWFUL IN YOUR JURISDICTION WILL APPLY TO YOU AND OUR LIABILITY WILL BE LIMITED TO THE MAXIMUM EXTENT PERMITTED BY LAW.

+
+12.4 NO ADVICE OR INFORMATION, WHETHER ORAL OR WRITTEN, OBTAINED BY YOU FROM GOOGLE OR THROUGH OR FROM THE SERVICE SHALL CREATE ANY WARRANTY NOT EXPRESSLY STATED IN THE TERMS.
+
+12.5 GOOGLE FURTHER EXPRESSLY DISCLAIMS ALL WARRANTIES AND CONDITIONS OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO THE IMPLIED WARRANTIES AND CONDITIONS OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT.
+
+13. LIMITATION OF LIABILITY
+
+13.1 SUBJECT TO OVERALL PROVISION IN PARAGRAPH 12.1 ABOVE, YOU EXPRESSLY UNDERSTAND AND AGREE THAT GOOGLE, ITS SUBSIDIARIES AND AFFILIATES, AND ITS LICENSORS SHALL NOT BE LIABLE TO YOU FOR:
+
+  (A) ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL CONSEQUENTIAL OR EXEMPLARY DAMAGES WHICH MAY BE INCURRED BY YOU, HOWEVER CAUSED AND UNDER ANY THEORY OF LIABILITY. THIS SHALL INCLUDE, BUT NOT BE LIMITED TO, ANY LOSS OF PROFIT (WHETHER INCURRED DIRECTLY OR INDIRECTLY), ANY LOSS OF GOODWILL OR BUSINESS REPUTATION, ANY LOSS OF DATA SUFFERED, COST OF PROCUREMENT OF SUBSTITUTE GOODS OR SERVICE, OR OTHER INTANGIBLE LOSS;
+
+  (B) ANY LOSS OR DAMAGE WHICH MAY BE INCURRED BY YOU, INCLUDING BUT NOT LIMITED TO LOSS OR DAMAGE AS A RESULT OF:
+
+    (I) ANY CHANGES WHICH GOOGLE MAY MAKE TO THE SERVICE, OR FOR ANY PERMANENT OR TEMPORARY CESSATION IN THE PROVISION OF THE SERVICE (OR ANY FEATURES WITHIN THE SERVICE);
+
+    (II) THE DELETION OF, CORRUPTION OF, OR FAILURE TO STORE, ANY CONTENT AND OTHER COMMUNICATIONS DATA MAINTAINED OR TRANSMITTED BY OR THROUGH YOUR USE OF THE SERVICE;
+
+    (III) YOUR FAILURE TO PROVIDE GOOGLE WITH ACCURATE ACCOUNT INFORMATION; OR
+
+    (IV) YOUR FAILURE TO KEEP YOUR PASSWORD OR ACCOUNT DETAILS SECURE AND CONFIDENTIAL.
+
+13.2 THE LIMITATIONS ON GOOGLE'S LIABILITY TO YOU IN PARAGRAPH 13.1 ABOVE SHALL APPLY WHETHER OR NOT GOOGLE HAS BEEN ADVISED OF OR SHOULD HAVE BEEN AWARE OF THE POSSIBILITY OF ANY SUCH LOSSES ARISING.
+
+14. Indemnification
+
+14.1 You agree to hold harmless and indemnify Google, and its subsidiaries, affiliates, officers, agents, employees, or licensors from and against any third party claim arising from or in any way related to (a) your breach of the Terms, (b) your use of the Service, or (c) your violation of applicable laws, rules or regulations in connection with the Service, including any liability or expense arising from all claims, losses, damages (actual and consequential), suits, judgments, litigation costs and attorneys' fees, of every kind and nature. In such a case, Google will provide you with written notice of such claim, suit or action.
+
+15. Changes to the Terms
+
+15.1 Due to things like changes to the law or changes to functionality offered through the Service, Google may need to change these Terms from time to time. You should look at the Terms regularly. We'll post notice of the modified Terms within, or through, the Service. Once the modified Terms are posted, the changes will become effective immediately, and you are deemed to have accepted the modified Terms if you continue to use the Service. If you do not agree to the modified Terms for the Service, please stop using the Service.
+
+16. General legal terms
+
+16.1 The Terms constitute the whole legal agreement between you and Google and govern your use of the Service (but excluding any service which Google may provide to you under a separate written agreement), and completely replace any prior agreements between you and Google in relation to the Service.
+
+16.2 You agree that Google may provide you with notices, including those regarding changes to the Terms, by email, regular mail, or postings on the Service.
+
+16.3 You agree that if Google does not exercise or enforce any legal right or remedy which is contained in the Terms (or which Google has the benefit of under any applicable law), this will not be taken to be a formal waiver of Google's rights and that those rights or remedies will still be available to Google.
+
+16.4 If any court of law, having the jurisdiction to decide on this matter, rules that any provision of these Terms is invalid, then that provision will be removed from the Terms without affecting the rest of the Terms. The remaining provisions of the Terms will continue to be valid and enforceable.
+
+16.5 You acknowledge and agree that each member of the group of companies of which Google is the parent shall be third party beneficiaries to the Terms and that such other companies shall be entitled to directly enforce, and rely upon, any provision of the Terms which confers a benefit on (or rights in favor of) them. Other than this, no other person or company shall be third party beneficiaries to the Terms.
+
+16.6 The Terms, and your relationship with Google under the Terms, shall be governed by the laws of the State of California without regard to its conflict of laws provisions. You and Google agree to submit to the exclusive jurisdiction of the courts located within the county of Santa Clara, California to resolve any legal matter arising from the Terms. Notwithstanding this, you agree that Google shall still be allowed to apply for injunctive remedies (or an equivalent type of urgent legal relief) in any jurisdiction.

+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the

+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+--------------------------------

+
+Each Contributor hereby grants You a world-wide, royalty-free,
+non-exclusive license:
+
+(a) under intellectual property rights (other than patent or trademark)
+    Licensable by such Contributor to use, reproduce, make available,
+    modify, display, perform, distribute, and otherwise exploit its
+    Contributions, either on an unmodified basis, with Modifications, or

+
+(b) under Patent Claims of such Contributor to make, use, sell, offer
+    for sale, have made, import, and otherwise transfer either its
+    Contributions or its Contributor Version.
+
+2.2. Effective Date
+
+The licenses granted in Section 2.1 with respect to any Contribution
+become effective for each Contribution on the date the Contributor first
+distributes such Contribution.
+
+2.3. Limitations on Grant Scope
+
+The licenses granted in this Section 2 are the only rights granted under
+this License. No additional rights or licenses will be implied from the
+distribution or licensing of Covered Software under this License.
+Notwithstanding Section 2.1(b) above, no patent license is granted by a
+Contributor:
+
+(a) for any code that a Contributor has removed from Covered Software;
+    or
+
+(b) for infringements caused by: (i) Your and any other third party's
+    modifications of Covered Software, or (ii) the combination of its
+    Contributions with other software (except as part of its Contributor
+    Version); or
+
+(c) under Patent Claims infringed by Covered Software in the absence of
+    its Contributions.
+
+This License does not grant any rights in the trademarks, service marks,
+or logos of any Contributor (except as may be necessary to comply with
+the notice requirements in Section 3.4).
+
+2.4. Subsequent Licenses
+
+No Contributor makes additional grants as a result of Your choice to
+distribute the Covered Software under a subsequent version of this
+License (see Section 10.2) or under the terms of a Secondary License (if
+permitted under the terms of Section 3.3).
+
+2.5. Representation
+
+Each Contributor represents that the Contributor believes its
+Contributions are its original creation(s) or it has sufficient rights
+to grant the rights to its Contributions conveyed by this License.
+
+2.6. Fair Use
+
+This License is not intended to limit any rights You have under
+applicable copyright doctrines of fair use, fair dealing, or other
+equivalents.
+
+2.7. Conditions
+
+Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
+in Section 2.1.
+
+3. Responsibilities
+-------------------
+
+3.1. Distribution of Source Form
+
+All distribution of Covered Software in Source Code Form, including any
+Modifications that You create or to which You contribute, must be under
+the terms of this License. You must inform recipients that the Source
+Code Form of the Covered Software is governed by the terms of this
+License, and how they can obtain a copy of this License. You may not
+attempt to alter or restrict the recipients' rights in the Source Code
+Form.
+
+3.2. Distribution of Executable Form
+
+If You distribute Covered Software in Executable Form then:
+
+(a) such Covered Software must also be made available in Source Code
+    Form, as described in Section 3.1, and You must inform recipients of
+    the Executable Form how they can obtain a copy of such Source Code
+    Form by reasonable means in a timely manner, at a charge no more
+    than the cost of distribution to the recipient; and
+
+(b) You may distribute such Executable Form under the terms of this
+    License, or sublicense it under different terms, provided that the
+    license for the Executable Form does not attempt to limit or alter
+    the recipients' rights in the Source Code Form under this License.
+
+3.3. Distribution of a Larger Work
+
+You may create and distribute a Larger Work under terms of Your choice,
+provided that You also comply with the requirements of this License for
+the Covered Software. If the Larger Work is a combination of Covered
+Software with a work governed by one or more Secondary Licenses, and the
+Covered Software is not Incompatible With Secondary Licenses, this
+License permits You to additionally distribute such Covered Software
+under the terms of such Secondary License(s), so that the recipient of
+the Larger Work may, at their option, further distribute the Covered
+Software under the terms of either this License or such Secondary
+License(s).
+
+3.4. Notices
+
+You may not remove or alter the substance of any license notices
+(including copyright notices, patent notices, disclaimers of warranty,
+or limitations of liability) contained within the Source Code Form of
+the Covered Software, except that You may alter any license notices to
+the extent required to remedy known factual inaccuracies.
+
+3.5. Application of Additional Terms
+
+You may choose to offer, and to charge a fee for, warranty, support,
+indemnity or liability obligations to one or more recipients of Covered
+Software. However, You may do so only on Your own behalf, and not on
+behalf of any Contributor. You must make it absolutely clear that any
+such warranty, support, indemnity, or liability obligation is offered by
+You alone, and You hereby agree to indemnify every Contributor for any
+liability incurred by such Contributor as a result of warranty, support,
+indemnity or liability terms You offer. You may include additional
+disclaimers of warranty and limitations of liability specific to any
+jurisdiction.
+
+4. Inability to Comply Due to Statute or Regulation
+---------------------------------------------------
+
+If it is impossible for You to comply with any of the terms of this
+License with respect to some or all of the Covered Software due to
+statute, judicial order, or regulation then You must: (a) comply with
+the terms of this License to the maximum extent possible; and (b)
+describe the limitations and the code they affect. Such description must
+be placed in a text file included with all distributions of the Covered
+Software under this License. Except to the extent prohibited by statute
+or regulation, such description must be sufficiently detailed for a
+recipient of ordinary skill to be able to understand it.
+
+5. Termination
+--------------
+
+5.1. The rights granted under this License will terminate automatically
+if You fail to comply with any of its terms. However, if You become
+compliant, then the rights granted under this License from a particular
+Contributor are reinstated (a) provisionally, unless and until such
+Contributor explicitly and finally terminates Your grants, and (b) on an
+ongoing basis, if such Contributor fails to notify You of the
+non-compliance by some reasonable means prior to 60 days after You have
+come back into compliance. Moreover, Your grants from a particular
+Contributor are reinstated on an ongoing basis if such Contributor
+notifies You of the non-compliance by some reasonable means, this is the
+first time You have received notice of non-compliance with this License
+from such Contributor, and You become compliant prior to 30 days after
+Your receipt of the notice.
+
+5.2. If You initiate litigation against any entity by asserting a patent
+infringement claim (excluding declaratory judgment actions,
+counter-claims, and cross-claims) alleging that a Contributor Version
+directly or indirectly infringes any patent, then the rights granted to
+You by any and all Contributors for the Covered Software under Section
+2.1 of this License shall terminate.
+
+5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+end user license agreements (excluding distributors and resellers) which
+have been validly granted by You or Your distributors under this License
+prior to termination shall survive termination.

+*  Covered Software is free of defects, merchantable, fit for a        *

+
+9. Miscellaneous
+----------------
+
+This License represents the complete agreement concerning the subject
+matter hereof. If any provision of this License is held to be
+unenforceable, such provision shall be reformed only to the extent
+necessary to make it enforceable. Any law or regulation which provides
+that the language of a contract shall be construed against the drafter
+shall not be used to construe this License against a Contributor.
+
+10. Versions of the License

+
+10.1. New Versions

+# Android KeePassDX
+
+<img src="https://raw.githubusercontent.com/Kunzisoft/KeePassDX/master/art/icon.png"> KeePassDX is a **multi-format KeePass manager for Android devices**. The app allows creating keys and passwords in a secure way by integrating with the Android design standards.
+
+<img src="https://raw.githubusercontent.com/Kunzisoft/KeePassDX/master/art/screen.jpg" width="220">
+
+### Features
+
+ - Create database files / entries and groups.
+ - Support for **.kdb** and **.kdbx** files (version 1 to 4) with AES - Twofish - ChaCha20 - Argon2 algorithm.
+ - **Compatible** with the majority of alternative programs (KeePass, KeePassX, KeePassXC, …).
+ - Allows opening and **copying URI / URL fields quickly**.
+ - **Biometric recognition** for fast unlocking *(fingerprint / face unlock / …)*.
+ - **One-Time Password** management *(HOTP / TOTP)* for Two-factor authentication (2FA).
+ - Material design with **themes**.
+ - **Auto-Fill** and Integration.
+ - Field filling **keyboard**.
+ - Dynamic **templates** 
+ - **History** of each entry.
+ - Precise management of **settings**.
+ - Code written in **native languages** *(Kotlin / Java / JNI / C)*.
+
+KeePassDX is **open source** and **ad-free**.
+
+## 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).*

-# Android Keepass DX
-
-<img src="https://raw.githubusercontent.com/Kunzisoft/KeePassDX/master/art/icon.png"> Keepass DX is a **multi-format KeePass manager for Android devices**. The application allows to create keys and passwords in a secure way by integrating with the Android design standards.
-
-<img src="https://raw.githubusercontent.com/Kunzisoft/KeePassDX/master/art/screen.jpg" width="220">

-
-Keepass DX is **open source** and **ad-free**. 
-
-## 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.
