Tab Drowse
Privacy policy
Last updated: 31 October 2026. Product: Tab Drowse.
The extension unloads eligible inactive tabs using the browser's native discard mechanism. The developer operates no backend for the extension. There is no account, advertising, analytics or telemetry in the extension.
Information processed on your device
The extension reads current tab information, including URLs, titles, site icons, active/pinned/audio/loading/discarded state, frame information and last-access times. It uses this information to choose eligible tabs, respect site exceptions, count discarded tabs and mark sleeping tabs. It does not request the browser history API or create a browsing-history archive.
Scripts run on HTTP and HTTPS pages and their supported frames. To detect unfinished work, they observe input and form-submission events and inspect input/textarea values, default values, editable text and focus, including within supported Shadow DOM and iframe editors. The check can encounter sensitive text, such as passwords, contact details, payment or health information, or message drafts, depending on the page. Password inputs are not excluded by the current check. Values are checked locally, not copied to extension storage or sent to the developer. References to edited fields are held in page memory while that document is loaded.
The extension checks audio/video playback position and state, live microphone/camera/screen-sharing track state and detected WebRTC call state. It does not record or upload audio, video or screen contents and does not initiate capture. It reads the existing notification permission state to avoid unloading sites where notifications are allowed. It does not request that permission or read notification messages. Page checks report a busy/not-busy result to the extension's background worker on the same device.
Information stored
chrome.storage.local: exact hostnames on your exception list (keep), the selected idle duration in minutes (idleMinutes) and the pause-end timestamp (pauseUntil). The idle duration remains until changed or the extension is uninstalled. Exceptions remain until removed or the extension is uninstalled. Resume removes the pause timestamp; an expired timestamp may remain stored until a later change or uninstall, but no longer pauses sleep.chrome.storage.session: a tab identifier and last-load timestamp (loaded:<tabId>), used to give a newly loaded tab the selected idle duration (fifteen minutes by default) before it becomes eligible. Entries are removed when the corresponding tab is removed/replaced; session storage is temporary and is cleared on browser restart and extension reload/update/disable.
The extension does not use browser-account storage sync. You can remove exceptions in the popup, resume sleep to remove the pause timestamp, or uninstall the extension to remove its local settings. No draft backup is stored.
Transfers, code and external websites
The extension does not transmit page contents, field values, tab addresses or settings to the developer or third parties. It uses the browser's internal favicon endpoint to read site icons, not an external icon service. Executable code is packaged with the extension; it does not download or execute remote code.
Reloading a sleeping tab makes ordinary requests to that website. Opening a link to a privacy or support website also makes ordinary browser requests to that destination. Those websites and the browser have their own data practices; this policy describes the extension itself.
Information accessed through browser APIs is used only for the tab-sleep functionality described here. Its use complies with the Chrome Web Store User Data Policy, including the Limited Use requirements. No data is sold, used for advertising or credit decisions, or transferred for unrelated purposes.
Questions: studio@artbrain.com.ua. Do not send passwords or private page contents with a support request. If you choose to email the developer, your email provider and the developer receive the information you include; the extension does not send support reports automatically.
