What data is accessed
ShortsTrack's content script runs only on www.youtube.com pages. It reads:
- The video ID (an 11-character code) from Shorts URLs on the page, to know which Short a thumbnail or player refers to.
- Playback position of the Short you're actively watching, to calculate how much of it you've seen.
It does not read video titles, thumbnails, channel names, comments, your Google account, or any other page content.
What data is stored
All of the following is stored locally in your browser via chrome.storage.local
and is never transmitted anywhere:
- A map of watched video IDs → watch progress (0–100%), a completed flag, and a last-updated timestamp.
- Your extension settings (Free/Pro state, whether "hide watched" is enabled).
- Free-tier history is automatically deleted after 7 days; Pro removes this limit.
What data is collected
None. ShortsTrack has no analytics, no telemetry, no crash reporting, and no third-party tracking scripts of any kind.
External servers & third-party services
| Service | When contacted | What's sent |
|---|---|---|
| api.lemonsqueezy.com | Only when you enter and activate a Pro license key on the Options page, and during an automatic re-check roughly every 6 hours if a key is active | The license key you entered, and an installation identifier (not tied to your identity). No browsing history, video IDs, or watch data are ever included. This request goes directly to Lemon Squeezy, our payment provider — never through unikdev.app's own servers. |
Free-tier use of ShortsTrack makes zero network requests.
