This Agreement is a legal agreement between you (the Customer) and Paulo Renato Centeno Holvorcem (the Licensor) for this software product, including the software, any associated media and documentation (collectively referred to as the Software). By installing, copying, or using the Software, the Customer agrees to be bound by the terms of this Agreement. If you do not agree to be bound by the terms of this Agreement, you must return the unused software to the vendor for a refund. In this case, you must not retain any copies of the software, its license key, or documentation, which you may have in your possession.

This Software is licensed (not sold), being the property of the Licensor and protected by copyright law. Upon payment of the license fee, the Licensor grants the Customer a non-exclusive and non-transferable license to use the Software, subject to the following limitations:

• You may use the Software to schedule observations and to carry out observations on a single telescope, whose aperture and location you must communicate to the Licensor. If you stop using the Software with one telescope and start using it with another telescope, the aperture and location of the second telescope must be immediately communicated to the Licensor; additional license fees may be due if the second telescope is larger than the first telescope. Communication of false information about the telescope with which the Software will be used, or omission of information about changes of telescope, is considered a violation of this agreement, and will be prosecuted to the full extent of law.
• You may install and use the Software on up to three computers, but, as described above, may use it to schedule observations and to carry out observations on a single telescope. To use the Software on more than three computers or with more than one telescope, you must have separate licenses for each telescope and/or additional computers.
• You may make one copy of the Software for archival purposes.
• You may not transfer the Software to third parties.
• You may not reveal the license key(s) provided to you by the Licensor to third parties.
• You may not share, sublicense, rent or lease all or any portion of the Software.
• You may not reverse engineer, decompile, disassemble, modify, translate, or create derivative works from the Software.
• You may not use the Software for paid public exhibition.

TITLE. Title, ownership rights, and intellectual property rights of the Software belong to the Licensor. The Customer acknowledges these rights and will not take any action which may jeopardize, limit, or interfere with the Licensor's rights with respect to the Software. Such actions could result in irreparable damage to the Licensor, which would then be entitled to injunctions and other equitable relief in addition to whatever remedies which may be provided by law. The Software is protected by copyright and other intellectual property laws, and by international treaties.

TERMINATION. If the Customer does not comply with the terms of this Agreement, the Licensor may terminate it. Upon termination, the Customer must return any Licensor-supplied media containing the Software (including its documentation) to the Licensor, and destroy any copies of the Software and its license key which may be in the Customer's possession.

LIMITED WARRANTY. The Licensor does not warrant that the Software is defect-free or will meet the Customer's requirements. This warranty is exclusive and in lieu of all other warranties, whether express or implied, including the implied warranties of merchantability, fitness for a particular use, and non-infringement.

LIMITATION OF LIABILITY. Under no circumstances shall the Licensor be liable to you for any special, consequential, indirect, or similar damages, including lost data, lost profit, work stoppage, computer failure or malfunction, or any commercial damages or losses, resulting from the use or misuse of the Software, even if the Licensor has been advised of the possibility of such damages. Under no circumstances shall the Licensor's liability exceed the value of the license fee paid by the Customer.
