Terms of use

Effective 25 October 2026 · last updated 25 October 2026

1. Scope

These terms apply when you use modernengineer.dev, including the website, accounts, the REST API and MCP. The service is run by Thiệu Nguyễn as an individual, personal tax ID 054090008718.

2. Accounts

  • You sign in with email or a linked account, and you keep that inbox secure.
  • Each account is for one person. Do not share reading access or API keys with anyone else.
  • I may suspend an account that breaks these terms and tell you by email, except in urgent cases such as a leaked API key or an attack on the system.

3. Content and license

Articles, videos and file packs are copyright Thiệu Nguyễn unless an article states another license. You may read them, use the files in your own work and quote them with a link to the original. You may modify and use the files in your own or your clients' projects, paid projects included. Do not resell, share publicly or republish articles or packs verbatim, modified versions included.

4. Subscriber access and paid packs

  • Subscriber access is personal, lasts for the term of your plan and can be revoked if these terms are broken.
  • Packs you bought can be downloaded again, updates included, while your plan is active. If the service shuts down, I will give at least 30 days' notice so you can download them.
  • Refunds follow the Refund policy.

5. API and agents

API keys belong to your account and have reasonable call limits, described in the API docs. Do not use the API to bulk-copy or redistribute paid content.

6. Limitation of liability

The content shares hands-on experience, not guaranteed professional advice. Judge it yourself before applying it to your systems. To the extent the law allows, my total liability to you is limited to what you paid for the service in the last 12 months.

7. Changes to these terms

When these terms change, I update the date at the top. Changes that affect your rights are announced by email at least 14 days ahead.

8. Governing law and contact

These terms are governed by the laws of Vietnam. Send questions to contact@modernengineer.dev.
