Terms of Service

NullStrike sells Claude Skills — markdown procedures designed to be loaded into Anthropic's Claude Code or similar Claude-based clients. Purchase is between you (the buyer) and the NullStrike operator.

On successful payment you receive a download link to one or more skill packages, delivered by email within minutes. Links are signed and expire 24 hours after issue. If a link expires before you can use it, reply to your order email and we'll issue a fresh one.

You receive a perpetual, non-transferable license to use the purchased skills:

• For yourself, on engagements you are authorized to perform.
• For your direct employer, on engagements your employer is authorized to perform.

You may not:

• Redistribute the skills publicly (paid, free, or as part of another product).
• Repackage the skills for resale.
• Use the skills against systems you do not own or do not have documented authorization to test.

You may:

• Modify the skills for your own use.
• Reference the skills in writeups, talks, or training (please credit NullStrike).

Because skills are digital goods delivered instantly, all sales are final.If the file is broken, missing, or the download is failing, email us and we'll make it right — but we do not issue refunds for "changed my mind" or "didn't use it."

If we update a skill you've purchased, we'll email you the new version at no extra cost. We do not guarantee any particular update cadence.

The skills are provided "as is." Penetration testing tools and procedures fail, generate false positives, miss findings, and produce side effects. You are the operator; you remain responsible for the outcome of every command you run. NullStrike disclaims all implied warranties to the maximum extent permitted by law.

To the maximum extent permitted by law, NullStrike's total liability for any claim arising from your use of the skills is limited to the amount you paid for them.

By purchasing, you confirm:

• You are at least 18 years old.
• You are buying for authorized security testing use.
• You have read and accept the Authorized-Use Disclaimer.
• You will not use the skills to commit crimes.
