Privacy Policy

MMU — Multi-Media Uploader · Effective date: July 9, 2026

MMU ("the App") is a personal desktop application that publishes short-form videos to the account owner's own social media accounts on YouTube, TikTok, Instagram, and Facebook using each platform's official API. The App runs entirely on the owner's local computer. It is operated by a single individual for their own accounts and is not offered as a service to third parties.

1. Information the App accesses

• OAuth access and refresh tokens issued by YouTube (Google), TikTok, and Meta (Instagram/Facebook) after the account owner explicitly authorizes the App.
• Account metadata returned by the platform APIs (e.g. channel or account identifiers, display names, creator posting options).
• Content the owner chooses to publish: video files, titles, captions, and tags, all created and stored locally by the owner.
• Post-publish statistics of the owner's own published videos (view, like, comment, and share counts) retrieved via the platform APIs.

2. How information is used

Tokens are used solely to upload and publish the owner's videos and to read statistics of the owner's own posts. Statistics are used solely to display performance history to the owner. No information is used for advertising, profiling, or any purpose other than operating the App for its owner.

3. Storage and security

All data — tokens, publish records, and statistics — is stored locally on the owner's computer. OAuth tokens are stored in the operating system's credential manager (Windows Credential Manager). No data is transmitted to any server other than the official platform APIs themselves.

4. Sharing

The App does not share, sell, or transmit any data to third parties. There are no third-party analytics, advertising SDKs, or tracking technologies.

5. Data retention and deletion

Data remains on the owner's computer until the owner deletes it. Platform authorization can be revoked at any time from each platform's security settings (Google Account permissions, TikTok app settings, Meta Business settings), which immediately invalidates the App's access. Local data can be removed by deleting the App's data directory.

6. YouTube API Services

The App uses YouTube API Services. By using it, the owner agrees to the YouTube Terms of Service and the Google Privacy Policy. The App accesses, stores, and uses YouTube data as described above, in accordance with the YouTube API Services Developer Policies. Stored YouTube data is limited to the owner's own authorized channel and can be deleted at any time as described in Section 5, or by revoking access via Google security settings.

7. Changes

Any changes to this policy will be posted on this page with an updated effective date.
