Privacy Policy

STKH App ("Sự thật khoa học") · Last updated: October 1, 2026

STKH App (the "App") is a personal desktop application that runs locally on the user's own computer. It has no server, no user accounts of its own, and no analytics. This policy explains what data the App handles and where it goes.

1. Data from TikTok

When you connect your TikTok account, the App receives:

• Your TikTok open ID, display name and avatar URL (scope user.info.basic), used only to show which account is connected.
• An access token and refresh token, used only to upload videos to your account when you ask it to (scopes video.upload and, if enabled, video.publish).
• Creator settings (such as allowed privacy levels), used only to show valid posting options.

Tokens are stored in a file on your own computer that only your user account can read. They are never sent anywhere except to TikTok's API.

2. Data sent to other services

• TikTok: the videos and captions you choose to upload.
• Microsoft Edge text-to-speech / Google Text-to-Speech: the voice-over text of your scripts, to generate audio.
• Pollinations: the image prompts of your scripts, to generate images.

None of your TikTok account data is sent to these voice or image services.

3. What the App does not do

• It does not sell, rent or share your data with anyone.
• It does not use cookies, tracking or advertising.
• It does not read your TikTok videos, followers, messages or any data beyond what is listed above.

4. Retention and deletion

Data stays on your computer until you delete it. Clicking "Disconnect" in the App deletes the stored TikTok tokens. You can also revoke the App's access in your TikTok account settings, and delete the App's data folder to remove all locally stored data.

5. Children

The App is not intended for children under 13 (or the minimum age required by TikTok in your country).

6. Changes

This policy may be updated from time to time. The "Last updated" date above shows when it last changed.

7. Contact
