Educational use only
The techniques taught here are dual-use: they can protect systems or attack them. Skills go where the wielder points them.
By accessing the course you agree that:
- You will not attack systems you do not own or lack written authorisation to test.
- You accept full responsibility for how you apply these techniques.
- DevLune and the author are not responsible for misuse.
- Some techniques are restricted in some jurisdictions (game cheats in Germany, certain tooling in the United Kingdom, and others). Consult your local law.
- Nothing here constitutes legal advice.
If you do not agree with these terms, do not proceed.
What you get
One personal, non-transferable licence to read the course under the email address you use at checkout. Access is lifetime — as long as DevLune runs the site — and covers every future update to the same course.
Every page is watermarked with your email
The reader renders a low-opacity watermark tiling your email, a short account id and the date across every lesson. This is intentional — it does not obscure the content, and it makes any copy that appears elsewhere traceable to the account it came from. Screenshots and printouts carry the same mark.
If access is misused
Signals we act on include a mass fetch spike, repeated fingerprint changes on the same account, or a copy appearing in public that matches the watermark on this account. When those show up together, we pause access without notice and reach out on the buyer's email. Innocent explanations are the norm, and access is restored once things check out.
Refund window
Full refund within seven days of purchase, provided you have opened fewer than three lessons. Refunds after that are handled case-by-case — write to sidharth@devlune.in with the reason. No refund on gifted or promotional access.
Lawful use only
The course covers reverse engineering, patching, hooking and license bypass techniques. It teaches these against fictional targets and against real binaries you own or have written authorisation to analyse — security research, interoperability, malware analysis, and personal fair-use. It is not authorisation to touch systems, licences or platforms you do not have permission to work on. You agree not to use the material for those, and you understand that DevLune is not liable for what you do with it.
No warranty
The course is provided as-is. Every technique changes over time, some faster than others (kernel-mode anticheat is the extreme). Where a technique needs re-derivation against a live target the course says so; where a tool has moved on, we replace the lesson at the next update. No guarantee is made that any specific technique currently works against any specific product, and no guarantee is made about the outcome of any particular attempt.
