LIFF Terms of Use

1. Scope

These Terms apply when you open or use Samta through the LINE Front-end Framework (LIFF) or the LINE in-app browser, including LINE login and LIFF display. If you do not agree to these Terms or the main Terms, do not use Samta via LIFF.

2. Relation to the main Terms

• These LIFF Terms supplement the main Terms of Use.
• If there is a conflict on LIFF / LINE-specific matters, these LIFF Terms prevail for that matter.
• All other topics (service nature, liability, IP, etc.) follow the main Terms.
• Thai versions of the main Terms and LIFF Terms are primary; English pages are for convenience.

3. LINE in-app browser (LIFF)

• When opened via LIFF, the service runs inside LINE’s in-app browser environment.
• Cookies, storage, and browser capabilities may differ from an external browser.
• Updates to the LINE app, OS, or LINE policies may affect LIFF behaviour.
• We do not control LINE Corporation’s policies or the LINE app itself.

4. LIFF login and profile

• You may sign in with LINE via LIFF when that feature is enabled.
• If you authorize it, we may receive LINE profile data such as display name, profile image, and a user identifier (within LINE’s and your granted scopes).
• You are responsible for the security of your LINE account and the permissions you grant.
• You may revoke access or stop using the service via channels supported by LINE and our app.

5. Data obtained from LINE

LINE data we may process when you use LIFF is generally used to:

• Authenticate and create/link a Samta account
• Show your display name or profile image in the app (if available)
• Provide logged-in features and improve the experience

We do not request more data than needed to operate the service, and we do not sell your personal data. See Privacy below and the main Terms for more.

6. Google vs LINE account linking

• You may sign in with Google or LINE (LIFF), or use guest mode if enabled.
• Accounts from different identity providers may not merge automatically unless an in-app linking flow exists and you complete it.
• Subscriptions, history, and profile data may be tied to the sign-in method used — use the same method to access the same account.
• To request account merge or data migration, contact us via the feedback form.

7. Entertainment / education — not professional advice

Astrology, timing (“yam”), and charts shown in LIFF are for entertainment and education only. They are not medical, legal, financial, investment, or other professional advice. Do not rely on them instead of qualified professionals. Outcomes may be incomplete or inaccurate.

8. Payments when opened in LIFF

• If you subscribe or pay while using LIFF, the main Terms on payments apply (typically via Stripe).
• Methods may include PromptPay, cards, and Apple Pay where supported by Stripe, your device, our domain, and the LIFF environment.
• The LINE in-app browser may limit some payment methods or Checkout behaviour — you may need an external browser.
• A subscription takes effect when Stripe payment succeeds. If no charge is made, access follows what the app shows (for example a trial).

9. Privacy and PDPA

Personal data (including LINE data you authorize) is handled under our Consent & Personal Data Notice (PDPA / GDPR-aligned) and applicable Thai law, including the Personal Data Protection Act B.E. 2562 (PDPA) as applicable. Data is generally used to operate the service, authenticate users, process payments (if any), and improve the product (optional analytics/marketing only with your consent on the consent page).

10. Contact and feedback

Contact the Samta platform operator via the feedback form or channels announced by the admin.

11. Governing law and updates

These LIFF Terms are governed by the laws of Thailand. Disputes are subject to Thai courts, except where consumer law requires otherwise. We may update this document; continued use via LIFF after the “Last updated” date means you accept the revised Terms.
