CALC AI Proprietary License and Terms of Use

Last updated: November 15, 2026 · Copyright © 2026 CALC AI. All rights reserved.

These terms cover the CALC AI firmware and source code, the firmware files, and this flasher website and everything on it (together, “the Software”). The Software is licensed, not sold. By using this website or the Software, you agree to these terms. If you do not agree, do not use them.

  1. What you may do

    If you bought a CALC AI calculator, you may use this website to install or update CALC AI firmware on the CALC AI calculator you own, for your own personal use. Nothing else is permitted unless CALC AI gives you written permission.

  2. What you may not do

    Without CALC AI’s written permission, you may not:

    1. Sell, resell, rent, lease, license or otherwise give the Software, or any part of it, to anyone else, whether or not you charge for it.
    2. Use the Software, or any part of it, to make, build, flash or sell any product or service, including calculators or boards that you sell or give to other people.
    3. Share, publish, upload, post, send or otherwise make available the Software, its source code, its firmware files, or any copy of them, including copies captured from this website or read back from a board.
    4. Copy, download, extract, decompile, disassemble, reverse engineer or modify the Software, except where the law expressly allows it despite this restriction.
    5. Get around, disable or interfere with any part of this website, including its protections.

  3. Ending your permission

    If you break these terms, your permission to use the Software ends immediately, and you must stop using it and destroy any copies you have.

  4. Enforcement

    Breaking these terms infringes CALC AI’s copyright and breaches this agreement. Violations will result in legal action. CALC AI may seek damages, an injunction, and its legal costs and attorney’s fees wherever the law allows.

  5. Open-source parts

    The firmware and this website include open-source components made by others (for example the ESP32 Arduino core and libraries, and esptool-js). Those components stay under their own licenses, and nothing in these terms limits any right those licenses give you. Everything else in the Software belongs to CALC AI.

  6. No warranty

    The Software is provided “as is”, without warranties of any kind, to the fullest extent the law allows. Follow the instructions on this website, including taking a battery out before connecting USB-C. To the fullest extent the law allows, CALC AI is not liable for any indirect, incidental or consequential damages from using the Software or this website.

  7. Changes

    CALC AI may update these terms. The version on this website at the time you use it applies.

  8. Contact
