TEXAS INSTRUMENTS APP SOFTWARE LICENSE AGREEMENT

By downloading the software and/or documentation you agree to abide by the following provisions.

  1. License: Subject to your payment of any applicable license fee, Texas Instruments Incorporated ("TI") grants you a license to copy and use the software program(s) on a TI calculator and copy and use the documentation from the linked web page or CD ROM (both software programs and documentation being "Licensed Materials"). In addition to the copy resident on your calculator, you may keep a copy on your computer for backup / archive purposes only.

  2. Restrictions: You may not reverse-assemble or reverse-compile the software program portion of the Licensed Materials that are provided in object code format. You may not sell, rent or lease copies of the Licensed Materials. You may not use the Licensed Materials on any emulator of a TI calculator unless the emulator is obtained from TI.

  3. Support: Support for the Licensed Materials is described in the documentation that accompanies the software. Absent such documentation, support shall be provided by TI.

  4. Copyright: The Licensed Materials and any accompanying documentation are copyrighted. If you make copies, do not delete the copyright notice, trademark, or protective notices from the copies.

  5. Warranty: TI warrants that it has the right to provide the Licensed Materials. TI does not warrant that the Licensed Materials will be free from errors or will meet your specific requirements.

    The Licensed Materials are made available "AS IS" to you or any subsequent user.

    Although no warranty is given for the Licensed Material, the media (if any) will be replaced if found to be defective during the first three (3) months of use, when the package is returned postage prepaid to TI. THIS PARAGRAPH EXPRESSES TI'S MAXIMUM LIABILITY AND YOUR SOLE AND EXCLUSIVE REMEDY.

    Some states or jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation may not apply.

    This Agreement will immediately terminate if you fail to comply with its terms. Upon termination of this Agreement, you agree to return or destroy the original package and all whole or partial copies of the Program in your possession and so certify in writing to TI.
