Privacy Policy

Last updated: July 11, 2026

Volume Kit does not collect, store, or transmit any personal or usage data. Everything it does happens locally on your device.

Volume Kit ("the extension") is a Chrome extension that lets you adjust the playback volume of the browser tab you are using — boosting it up to 1000% or lowering it — with optional equalizer presets. This policy explains what the extension does and does not do with your information.

Data we collect

None. Volume Kit does not collect, transmit, sell, or share any personal information, browsing history, or usage analytics. There are no servers, no accounts, no tracking, and no third-party services. The developer has no access to any of your data.

Audio processing

The extension captures the audio of the active tab only after you interact with it, and processes that audio entirely on your device using the browser's built-in Web Audio engine. Audio is never recorded, stored, or sent anywhere — it passes through a volume and equalizer stage in real time and is played straight back to you.

Information stored on your device

To make the extension useful, a small amount of your own settings are saved locally using Chrome's storage API. This data stays on your device (and syncs only through your own Chrome profile if you have Chrome Sync enabled). It includes:

Per-site volume level and equalizer preset, so each website's setting is restored on your next visit.
Interface preferences, such as the selected theme and color mode.

This information is never transmitted to the developer or any third party. You can clear it at any time by removing the extension or clearing its data in Chrome.

Permissions

Volume Kit requests only the permissions required to control tab volume: activeTab, tabCapture, offscreen, tabs, and storage. It uses no content scripts, does not read the content of web pages, does not access all websites, and does not intercept network requests. Each permission is used solely to capture and adjust the current tab's audio and to remember your settings locally.

Children's privacy

Volume Kit is a general-purpose utility and is not directed at children. Because it collects no data, it does not knowingly collect information from anyone, including children.

Changes to this policy

If this policy changes, the updated version will be posted on this page with a new "Last updated" date.
