Privacy Policy

Effective date: 23 September 2026

This is a plain-language draft written to accurately describe what the TikTok Viral Clipper desktop app actually does. It is not legal advice, and hasn't been reviewed by a lawyer. If you're relying on this for a business, jurisdiction-specific compliance (UK GDPR, EU GDPR, CCPA, etc.), or anything beyond satisfying a developer-app registration, have it reviewed before treating it as final.

TikTok Viral Clipper ("the app") is a desktop application. This policy explains what data the app accesses, where it goes, and who can see it.

The short version

The app runs entirely on your own computer. There is no server operated by the developer that your videos, transcripts, or TikTok/YouTube account data are sent to, pass through, or are stored on. Anything the app needs to remember (your API key, sign-in tokens, settings) is saved in a local file on your own device, never uploaded anywhere by the developer.

What the app accesses, and why

Video you provide

You give the app either a local video file or a publicly available Live VOD URL. If it's a URL, the app downloads that video directly from its source to your computer using the open-source tool yt-dlp -- this traffic goes straight from your device to the video's host, not through any server the developer runs.

Transcription

The app transcribes the video's audio locally, on your own computer, using the open-source faster-whisper library. The video and its transcript never leave your device for this step.

AI analysis (Anthropic's Claude API)

To identify likely-viral moments, the app sends the video's transcript text directly from your device to Anthropic's Claude API, using an API key you provide and control yourself. The developer does not see, receive, or store this data -- it goes straight from your computer to Anthropic. Anthropic's own privacy policy governs their handling of that request; see anthropic.com/legal/privacy.

TikTok account access

If you choose to connect TikTok (to schedule posts), the app uses TikTok's own OAuth sign-in -- you log in directly with TikTok in your browser, and TikTok issues an access token straight to the app running on your device. That token is saved in a local file on your computer (alongside the app's other settings) so you don't have to sign in every time. The developer's infrastructure never receives this token; there is none to receive it, since the app has no backend server. When you post a clip, the video file and caption are uploaded directly from your device to TikTok's Content Posting API using that token.

Until a TikTok developer app has passed TikTok's own audit, posts made this way land as private ("only me") drafts in your TikTok inbox rather than going out publicly -- a TikTok platform restriction, not something this app or policy controls.

YouTube account access

Connecting YouTube works the same way: you sign in directly with Google's own OAuth consent screen, using OAuth client credentials you download yourself from Google Cloud Console. The resulting token is saved locally on your device. Uploading a clip sends it directly from your device to the YouTube Data API using that token.

What's stored, and where

All of the following live only in a local folder on your own computer, never on a server:

Your Anthropic API key
Your TikTok Client key/secret and sign-in token
Your YouTube OAuth client file and sign-in token
App settings (output folder, clip-length preferences, etc.)
Your scheduled-post queue and its history
Downloaded videos and exported clips

On Windows this is %APPDATA%\TikTokClipper\. Deleting that folder removes all of it. Uninstalling the app does not delete it automatically, so you can reinstall without re-entering everything -- delete the folder yourself if you want a clean wipe.

What the developer does and doesn't do with your data

The developer does not operate a server that the app talks to, does not collect analytics or telemetry from the app, and has no access to your videos, transcripts, API keys, or TikTok/ YouTube tokens -- these never leave your device except to go directly to the third-party service you've asked the app to use (Anthropic, TikTok, YouTube, or the site hosting a video you gave it a URL for), under your own credentials.

Third parties involved

Depending on which features you use, your data may reach these services directly from your device:

Anthropic (Claude API) -- transcript text, for AI analysis.
TikTok (Content Posting API / Login Kit) -- account sign-in and any clips you choose to post.
Google/YouTube (YouTube Data API) -- account sign-in and any clips you choose to upload.
The host of a video URL you provide (e.g. TikTok's own CDN for a Live VOD link) -- to download the video.

Each of these is governed by that provider's own privacy policy, not this one.

Children's privacy

This app is not directed at children and is not knowingly used to collect data from children.

Changes to this policy

If this policy changes, the updated version will be posted at this URL with a new effective date.
