RadaeePDF SDK 

Software license agreement for RadaeePDF SDK, formerly PDFViewer SDK

Please read carefully: by using the library (as defined below) and/or clicking on the 'accept' button below, you (either on behalf of yourself as an individual or on behalf of an entity as its authorized representative) agree to all of the terms of this end user license agreement regarding the use of the software. If you agree with all of the terms of this agreement, click on the 'Agree' button: you will be able to download the SDK.


Subject to the terms below (the 'Agreement'), Radaee Studio (“Radaee”) hereby grants you a non-exclusive, non-transferable license to use the dynamic library RadaeePDF SDK (the 'Software').

Here Radaee is represented by GEAR.it s.r.l., Italy (“GEAR.it”).

This EULA applies to the product RadaeePDF SDK, formerly RadaeePDF SDK.

1.1 You are permitted to use the software for development and internal purposes for free and without developers number limitation.

1.2 The Software can be distributed in your applications only with a valid license. You can share the full SDK package inside your company or working team. Any other distribution, transmitted via email, physical media, website or other electronic delivery system is not allowed.

1.3 You may copy the Software for back-up or archival purposes.

1.4 Applications using unlicensed version of RadaeePDF SDK shall be used only for development, testing, demoing purposes. Developers can distribute, publish, sell application only containing licensed RadaeePDF SDK. Each license will be strictly tied to a unique application package. 

1.5 Each application, identified by a unique application package name (on Android), bundle id (on iOS), unique name/uuid (on MS Windows platforms) needs a single commercial license for each Operating System. The developer can then distribute that licensed application on the Apple AppStore, Ms Store, Google Play and other public marketplaces. The user is allowed to distribute generated binaries though private repository. The user is not allowed to distribute binaries as preloaded Application in devices (ie.: builtin as system app, oem app, odm, app, etc.).

1.6 For the avoidance of doubt, the delivery for use by third parties is not covered by the free use license.

1.7 Each license should be tied to a single self contained application running in a specific OS environment: no external plugins, software module, printer driver (i.e.: via Android intent mechanism) should contain the RadaeePDF SDK binary library, java code or activation key.

1.8 OEMs, device manufacturers and distributors need a special “OEM license” to be able to distribute applications containing RadaeePDF SDK library bundled with their own devices. To obtain the correct license you must write to sales@radaeepdf.com

To know the correct price for this supplementary use, write to sales@radaeepdf.com.

1.9 The dynamic library, when packaged within your binary application, may be redistributed royalty free, as long as it is produced using a licensed version of the Software.

1.10 Developers could use, modify and extract any part of the source code they will find in the original distribution package (i.e.: demo project).

1.11 Doing any reverse engineering techniques on binaries, compiled code and native libraries is explicitly forbidden.

Developers who bought Professional or Premium license are eligible to get source codes from Android Java wrapper and interfaces.

1.12 Anyway, GEAR.it and Radaee are not liable for any claim, direct or indirect, and damages resulting from the use of the product arising out of this agreement, except if it is specified and extraordinary allowed. For that product GEAR.it and Radaee are not able to provide support and guarantee its good use.

1.13 Every developer and customer is eligible to receive software update for free.

Licensed version of the library will stay still valid from a RadaeePDF SDK version to a newer one.

Software activation keys won’t be affected by software updates.

2) TITLE: You acknowledge that no title to the intellectual property in the Software is transferred to you. Title, ownership, rights, and intellectual property rights in and to the Software shall remain that of Radaee and GEAR.it. Copyright and patent laws of Italy and international treaties protect the Software.



3.1        Each party represents and warrants to the other party that, by using the library – covered by this license – when making the download and using it to build up their own applications, automatically accepts all the terms of this agreement.

In particular:

(a)        it is duly organized, validly existing and in good standing as a corporation or other entity as represented herein under the laws and regulations of its jurisdiction of incorporation, organization or chartering;

(b)        it has the full right, power and authority to enter into this Agreement, to grant the rights and licenses granted hereunder and to perform its obligations hereunder;

(c) when executed and delivered by such party, this Agreement will constitute the legal, valid and binding obligation of such party, enforceable against such party in accordance with its terms; and

(d) in the case of GEAR.it only, GEAR.it represents and warrants that it has the authority to bind Radaee as set forth in this Agreement.

3.2 You agree that both GEAR.it and Radaee has made no express warranties, oral or written, to you regarding the products and that the products are being provided to you 'as is' without warranty of any kind. Radaee disclaims any and all other warranties, whether expressed, implied, or statutory. Your rights may vary depending on the state in which you live. Both GEAR.it and Radaee shall not be liable for indirect, incidental, special, cover, reliance, or consequential damages resulting from the use of this product.


You use this library solely at your own risk. In no event shall both GEAR.it and Radaee be liable to you for any damages, including but not limited to any loss, or other incidental, indirect or consequential damages of any kind arising out of the use of the software, even if both GEAR.it and Radaee has been advised of the possibility of such damages. In no event will both GEAR.it and Radaee be liable for any claim, whether in contract, tort, or any other theory of liability, exceed the cost of the software.

The use of the SDK and its license have no time limit.

Anyway, this Agreement shall terminate automatically if you fail to comply with the limitations described in this Agreement. No notice shall be required to effectuate such termination. Upon termination, you must remove and destroy all copies of the Software.

In the event of failure to destroy all copies of the Software, GEAR.it reserves the right to take legal action for damages.
