+6. GMP
+
+GMP is a free library for arbitrary precision arithmetic, operating on signed integers, rational numbers, and floating point numbers.
+GMP is distributed under the GNU LGPL <http://www.gnu.org/copyleft/lesser.html>. This license makes the library free to use, share, and improve, and allows you to pass on the result. The license gives freedoms, but also sets firm restrictions on the use with non-free programs.
+
+GMP is part of the GNU project. For more information about the GNU project, please see the official GNU web site <https://www.gnu.org/>.

+
+GNU LESSER GENERAL PUBLIC LICENSE
+
+Version 3, 29 June 2007
+
+Copyright © 2007 Free Software Foundation, Inc. <http://fsf.org/ >
+
+Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
+
+This version of the GNU Lesser General Public License incorporates the terms and conditions of version 3 of the GNU General Public License, supplemented by the additional permissions listed below.
+
+0. Additional Definitions.
+
+As used herein, “this License” refers to version 3 of the GNU Lesser General Public License, and the “GNU GPL” refers to version 3 of the GNU General Public License.
+
+“The Library” refers to a covered work governed by this License, other than an Application or a Combined Work as defined below.
+
+An “Application” is any work that makes use of an interface provided by the Library, but which is not otherwise based on the Library. Defining a subclass of a class defined by the Library is deemed a mode of using an interface provided by the Library.
+
+A “Combined Work” is a work produced by combining or linking an Application with the Library. The particular version of the Library with which the Combined Work was made is also called the “Linked Version”.
+
+The “Minimal Corresponding Source” for a Combined Work means the Corresponding Source for the Combined Work, excluding any source code for portions of the Combined Work that, considered in isolation, are based on the Application, and not on the Linked Version.
+
+The “Corresponding Application Code” for a Combined Work means the object code and/or source code for the Application, including any data and utility programs needed for reproducing the Combined Work from the Application, but excluding the System Libraries of the Combined Work.
+
+1. Exception to Section 3 of the GNU GPL.
+
+You may convey a covered work under sections 3 and 4 of this License without being bound by section 3 of the GNU GPL.
+
+2. Conveying Modified Versions.
+
+If you modify a copy of the Library, and, in your modifications, a facility refers to a function or data to be supplied by an Application that uses the facility (other than as an argument passed when the facility is invoked), then you may convey a copy of the modified version:
+
+    a) under this License, provided that you make a good faith effort to ensure that, in the event an Application does not supply the function or data, the facility still operates, and performs whatever part of its purpose remains meaningful, or
+    b) under the GNU GPL, with none of the additional permissions of this License applicable to that copy.
+
+3. Object Code Incorporating Material from Library Header Files.
+
+The object code form of an Application may incorporate material from a header file that is part of the Library. You may convey such object code under terms of your choice, provided that, if the incorporated material is not limited to numerical parameters, data structure layouts and accessors, or small macros, inline functions and templates (ten or fewer lines in length), you do both of the following:
+
+    a) Give prominent notice with each copy of the object code that the Library is used in it and that the Library and its use are covered by this License.
+    b) Accompany the object code with a copy of the GNU GPL and this license document.
+
+4. Combined Works.
+
+You may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work and reverse engineering for debugging such modifications, if you also do each of the following:
+
+    a) Give prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are covered by this License.
+    b) Accompany the Combined Work with a copy of the GNU GPL and this license document.
+    c) For a Combined Work that displays copyright notices during execution, include the copyright notice for the Library among these notices, as well as a reference directing the user to the copies of the GNU GPL and this license document.
+    d) Do one of the following:
+        0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.
+        1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version.
+    e) Provide Installation Information, but only if you would otherwise be required to provide such information under section 6 of the GNU GPL, and only to the extent that such information is necessary to install and execute a modified version of the Combined Work produced by recombining or relinking the Application with a modified version of the Linked Version. (If you use option 4d0, the Installation Information must accompany the Minimal Corresponding Source and Corresponding Application Code. If you use option 4d1, you must provide the Installation Information in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.)
+
+5. Combined Libraries.
+
+You may place library facilities that are a work based on the Library side by side in a single library together with other library facilities that are not Applications and are not covered by this License, and convey such a combined library under terms of your choice, if you do both of the following:
+
+    a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities, conveyed under the terms of this License.
+    b) Give prominent notice with the combined library that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work.
+
+6. Revised Versions of the GNU Lesser General Public License.
+
+The Free Software Foundation may publish revised and/or new versions of the GNU Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Library as you received it specifies that a certain numbered version of the GNU Lesser General Public License “or any later version” applies to it, you have the option of following the terms and conditions either of that published version or of any later version published by the Free Software Foundation. If the Library as you received it does not specify a version number of the GNU Lesser General Public License, you may choose any version of the GNU Lesser General Public License ever published by the Free Software Foundation.
+
+If the Library as you received it specifies that a proxy can decide whether future versions of the GNU Lesser General Public License shall apply, that proxy's public statement of acceptance of any version is permanent authorization for you to choose that version for the Library.

+8. PCRE2 LICENCE
+
+PCRE2 is a library of functions to support regular expressions whose syntax and semantics are as close as possible to those of the Perl 5 language.
+Release 10 of PCRE2 is distributed under the terms of the "BSD" licence, as specified below, with one exemption for certain binary redistributions. The documentation for PCRE2, supplied in the "doc" directory, is distributed under the same terms as the software itself. The data in the testdata directory is not copyrighted and is in the public domain.
+The basic library functions are written in C and are freestanding. Also included in the distribution is a just-in-time compiler that can be used to optimize pattern matching. This is an optional feature that can be omitted when the library is built.

+Das LfSt wird nach seiner Wahl und auf seine Kosten entweder die Steuersoftware so ändern oder ersetzen, dass das Schutzrecht nicht weiter verletzt wird, oder den Steuerbürger von Lizenzgebühren gegenüber dem Schutzrechtsinhaber oder Dritten freistellen.
+Gelingt dies dem LfSt zu angemessenen Bedingungen nicht, wird das LfSt dies dem Steuerbürger mitteilen und ihm die Nutzung ab einem bestimmten Zeitpunkt untersagen. Der Steuerbürger ist nach Wahl des LfSt verpflichtet, die Steuersoftware einschließlich der Dokumentation und aller Kopien entweder zu löschen oder an das LfSt zurückzugeben.
+(2) Voraussetzungen für die Haftung des LfSt nach § 8 Absatz 1 sind, dass der Steuerbürger das LfSt von Ansprüchen Dritter unverzüglich verständigt, die behauptete Schutzrechtsverletzung nicht anerkennt und jegliche Auseinandersetzung, einschließlich etwaiger außergerichtlicher Regelungen, entweder dem LfSt überlässt oder nur im Einvernehmen mit dem LfSt führt. Die dem Steuerbürger nach Verständigung des LfSt durch die Rechtsverteidigung entstandenen, notwendigen Gerichts- und Anwaltskosten gehen zu Lasten der Steuerverwaltung.
+Stellt der Steuerbürger die Nutzung der Steuersoftware aus Schadensminderungs- oder sonstigen wichtigen Gründen ein, ist er verpflichtet, den Dritten darauf hinzuweisen, dass mit der Nutzungseinstellung ein Anerkenntnis der behaupteten Schutzrechtsverletzung nicht verbunden ist.
+(3) Soweit der Steuerbürger die Schutzrechtsverletzung selbst zu vertreten hat, sind Ansprüche gegen das LfSt ausgeschlossen.
+(4) Weitergehende Ansprüche des Steuerbürgers wegen einer Verletzung von Schutzrechten Dritter sind ausgeschlossen. Dieser Ausschluss gilt nicht bei Vorsatz, grober Fahrlässigkeit und bei der Verletzung des Lebens, des Körpers oder der Gesundheit. Die Regelung in § 6 Absatz 1 bleibt hiervon unberührt.
+
+§ 9 Ein- und Ausfuhrkontrolle
+
+Es liegt in der Verantwortung des Steuerbürgers, alle anwendbaren Ein- und Ausfuhrbestimmungen einzuhalten. Der Steuerbürger wird darauf hingewiesen, dass das ElsterFormular auch kryptographische Techniken verwendet (OpenSSL).
+
+§ 10 Datenschutzhinweis
+
+(1) Mit dieser Software werden personenbezogene Daten im Sinne des Art. 4 Nr. 1 Datenschutzgrundverordnung (DSGVO) und Art. 9 Abs. 1 DSGVO zum Zwecke der Verarbeitung erhoben. Neben den reinen Daten, die zur Steuerveranlagung benötigt werden, erhebt die Software Daten über die Art des Betriebssystems des Nutzers und übermittelt diese an die Finanzverwaltung. Diese Daten werden benötigt, um die ordnungsgemäße Verarbeitung der Daten sicherzustellen und Fehlern im Verarbeitungsprozess vorzubeugen. Die Nutzung der Daten erfolgt im Rahmen des Art. 6 Abs. 1 UAbs. 1 Buchst. e i.V.m. Abs. 3 UAbs. 1 Buchst. b DSGVO i.V.m. bundes- bzw. landesgesetzlicher Steuergesetze durch die Finanzverwaltung und nur für den genannten Zweck.
+(2) Im Rahmen der Anwendung werden Protokolldateien erstellt und lokal gespeichert. Die Protokolldateien verbleiben lokal beim Steuerbürger. Lediglich im Supportfall können sie nach ausdrücklicher Erlaubnis des Steuerbürgers an den ELSTER-Support übermittelt werden.
+
+§ 11 Wirksamkeitsklausel
+
+Die Unwirksamkeit einer Bestimmung dieses Vertrages berührt den übrigen Vertragsinhalt nicht.
+
+§ 12 Deutsches Recht
+
+Auf diesen Vertrag ist ausschließlich deutsches Recht mit Ausnahme des EGBGB anwendbar.
