Privacy Policy

Effective date: September 19, 2026

This Privacy Policy explains how Nha Si Ech Dental processes information when users connect supported accounts and use content management or publishing features.

1. Information we process

Depending on the permissions a user grants, we may process basic TikTok profile information, user or account identifiers, OAuth access and refresh tokens, creator settings returned by TikTok, video and caption metadata, publishing selections, post identifiers, status information and technical logs needed to operate and secure the service.

2. How information is obtained

Account information and authorization tokens are obtained through TikTok Login Kit and TikTok APIs after the user grants requested permissions. Content information is provided or selected by the user through the service.

3. How we use information

We use information to authenticate authorized users, display the connected account, retrieve available creator and privacy settings, submit user-confirmed posts, refresh authorized sessions, report publishing status, prevent abuse, troubleshoot errors and maintain service security.

4. Sharing

Information is shared with TikTok when required to provide authorized TikTok features, and may be processed by infrastructure or automation providers used to operate the service. We do not sell personal information or use TikTok user data for unrelated advertising profiles.

5. Token and data security

Authorization tokens should be handled server-side and are treated as sensitive credentials. We apply reasonable technical and organizational measures to reduce unauthorized access, disclosure or misuse.

6. Retention

We retain information only for as long as reasonably necessary to provide the authorized features, maintain required records, resolve security issues or comply with applicable obligations. Tokens may become unusable when they expire or when the user revokes authorization.

7. User choices

Users may revoke TikTok authorization through their TikTok settings. Users may also request deletion of service-held account connection information by contacting us. Revoking access may prevent publishing and account-related features from functioning.

8. Children

The service is not intended for children and should only be used by persons eligible to authorize the connected platform account and accept these terms.

9. Changes

We may update this policy as the service or platform requirements change. The effective date above will be updated when material revisions are made.

10. Contact

Privacy questions or deletion requests may be sent to contact@huyhanhmarketing.io.vn.
