Refund policy

Last updated: 6 November 2026

Kits are digital products that can be copied once downloaded, so we cannot offer "change of mind" refunds. We do stand behind them working:

Full refund if the kit does not work

• If, within 7 days of purchase, the kit does not install or the demo does not start on a supported system (Windows 10/11 64-bit, Python 3.10-3.12, at least 8 GB RAM and 10 GB free disk), write to [email protected] with the error message.
• We will try to fix the problem with you. If we cannot fix it within 7 days of your e-mail, we refund the full price.
• Accidental duplicate purchases are refunded in full.

Not covered

• Unsupported systems (e.g. 32-bit Windows), or problems caused by changes you made to the code.
• Training speed on your hardware, or results that differ slightly from ours.
• Grades, project approval or any academic outcome.

How refunds are paid

To the original payment method, through our payment partner, usually within 5-10 working days after approval.
