If you don’t wish to transfer ownership of your feedback to us then please do not provide your feedback to us.

9.6.   Independent Development. Nothing in this Agreement will impair our, or our group companies’ or affiliates’ or partners’ right to develop, acquire, licence, market, promote or distribute games, products or technologies that perform the same or similar functions as, or otherwise compete with, any games, products or technologies you may create, whether using our Software and Services or not.


In order to use the Software and Services, you must (unless Improbable agrees otherwise in writing): (i) not copy the Software and Services (no back-up, archival or storage copies are permitted); (ii) not upload the Software and Services to the internet, servers or to any cloud based system permitted other than the Servers and as authorised by Improbable; (iii) not modify, merge, distribute, translate, reverse engineer, decompile, disassemble, create derivative works of, hack or interfere with the Software and Services or any part of it; (iv) only use SDKs and GDKs provided by or authorised by Improbable with the Software and Services; and (v) not use the Software and Services, or upload content to the Servers, in any way which breaches the Acceptable Use Policy; and (vi) not use our Software and Services to make or operate a competing virtual worlds platform.


Neither party will disclose confidential information to any third party and will only release the confidential information to those of its (or its group companies’, in the case of Improbable) directors, officers or employees who need to know it strictly for the purpose of exercising or performing that party's rights and obligations under this Agreement. Each receiving party will treat confidential information with the same degree of care and apply no lesser security measures than it affords to its own confidential information. The receiving party warrants that these measures provide adequate protection against unauthorised disclosure, copying or use. The receiving party will make no commercial use of the confidential information, except for the Purpose. Confidential information may be disclosed if and to the extent: (i) it is required by law, court order or other authority of competent jurisdiction or any regulatory or government authority to which the receiving party is subject, but in each case only to the extent required and for the purpose of such disclosure and provided that the disclosing party is promptly informed of the disclosure; (ii) the receiving party reasonably considers it necessary to disclose the information to its professional advisers, auditors or bankers provided that it does so on terms protecting the information; (iii) the information entered the public domain through no fault of the receiving party; (iv) the information was previously disclosed to the receiving party without any obligation of non disclosure; or (v) the disclosing party has given its consent in writing.
