Our Promise
We work hard to make Jam Kham reliable and effective. We use research-backed spaced repetition and continuously improve our platform.
The Legal Disclaimer
Jam Kham is provided "as is" without warranties of any kind, express or implied. We don't guarantee that:
- The service will be uninterrupted or error-free
- You'll achieve specific learning outcomes
- All bugs will be fixed immediately

No Professional Advice
Jam Kham is a language learning tool, not professional linguistic or educational advice. Use it as a supplement to, not a replacement for, comprehensive Thai language study.
9. Limitation of Liability
To the fullest extent permitted by law, Jam Kham and its founders shall not be liable for:
- Indirect, incidental, or consequential damages
- Loss of data, profits, or business opportunities
- Service interruptions or errors
- Actions of other users
Our total liability for any claim related to Jam Kham is limited to the amount you paid us in the 12 months before the claim, or $100, whichever is greater.
Some jurisdictions don't allow these limitations, so they may not apply to you.
10. Dispute Resolution
Talk to Us First
If you have a problem, please contact us at support@jamkham.com. We'll work with you to resolve it.
Governing Law
These Terms are governed by the laws of the United States and the state where Jam Kham is headquartered, without regard to conflict of law provisions.
Informal Resolution
Before filing any legal action, you agree to attempt informal resolution by contacting us. We'll try to resolve disputes within 60 days.
Arbitration
If informal resolution fails, disputes will be resolved through binding arbitration, not court. You waive the right to a jury trial or class action.
Exception: Either party can seek injunctive relief in court for intellectual property violations.
11. Changes to Terms
We may update these Terms from time to time. When we do:
- We'll update the "Last updated" date
- For material changes, we'll email you 30 days in advance
- The new terms take effect 30 days after notice
Your continued use after changes means you accept the new terms. If you don't agree, cancel your account before the changes take effect.
12. General Provisions
Entire Agreement
These Terms, along with our Privacy Policy and Cookie Policy, constitute the entire agreement between you and Jam Kham.
Severability
If any provision is found invalid, the rest of the Terms remain in effect.
No Waiver
Our failure to enforce any right doesn't waive that right.
Assignment
You can't transfer your rights under these Terms. We can assign our rights to another company (e.g., if acquired).
Force Majeure
We're not liable for delays or failures due to events beyond our reasonable control (natural disasters, wars, pandemics, etc.).
