Privacy Policy
Last updated: August 20, 2026
1. Overview
This tool (part of Hanzilingo) is a personal, internal utility operated by a single independent developer. It has no public-facing feature and no account registration, and it does not collect any data from any user.
2. Data We Process
The only data processed by this tool is a TikTok OAuth authorization token, obtained through TikTok's own official login and authorization screen. The developer never sees or has access to the TikTok account password at any point in this process.
3. How the Token Is Used
The authorization token is stored locally on the developer's own machine and used solely to publish videos to the developer's own TikTok account through TikTok's official Content Posting API.
4. Data Sharing
This data is never shared, sold, or disclosed to any third party.
5. Data Retention & Revocation
The token is kept only for as long as needed to operate the tool. Access can be revoked at any time from the TikTok account's connected apps settings, which immediately and permanently revokes this tool's access.
6. Changes to This Policy
This Privacy Policy may be updated at any time to reflect changes in how the tool operates.
