YouTube Chapter Builder

Privacy Policy

YouTube Chapter Builder processes chapter data locally in your browser.

Information handled

Chapter timestamps and titles that you type, import, or capture with Alt+C are stored using chrome.storage.local so they remain available on this device. The extension does not transmit, sell, or share this chapter data off the device.

No hidden services

Version 1.0.0 has no account, analytics, advertising, AI service, cloud sync, or backend service. The content script runs on YouTube pages only to provide timestamp capture and availability detection.

Clipboard and exports

TXT and CSV files are created only when you select an export action. Copy actions write chapter text to the clipboard only after you explicitly select a copy button.

Data control

Saved chapter data can be removed with the extension's clear control. Removing the extension clears its local extension storage according to Chrome's storage behavior.
