Everything TabNap stores — your tab list, protected sites, RAM savings — stays in Chrome's local storage on your device.
TabNap has no server. It cannot send your data anywhere, because there's nowhere for it to send it to.
No analytics, no ads, no account, no tracking, nothing sold or shared.
Uninstalling TabNap deletes everything it stored. Nothing persists anywhere else.
What TabNap is
TabNap is a Chrome extension that puts idle browser tabs to sleep — automatically under real memory pressure, or on a timer — and measures the RAM that actually gets freed. It runs entirely inside your browser. There is no TabNap server, account system, or backend of any kind.
What it stores, and where
TabNap keeps a small amount of data in chrome.storage.local — a storage area built into Chrome and scoped to your device. It is never transmitted, synced to a remote server, or readable by any other extension or website.
Tab metadata — URL, title, favicon, last-accessed time, and how often you switch to it. Used to decide which idle tabs are safe to sleep and which sleeping tab to wake first.
Your protected-sites list — any domains you've told TabNap to never sleep.
Measured RAM savings — the running total shown in the sidepanel, calculated from your device's own free-memory readings.
Full Memory Scan results — per-tab measurements, kept only until your next scan.
None of this is bundled, exported, or made available to TabNap's developer. There is nothing to send it to — the code that would need to exist to do that simply isn't in the extension.
Permissions, and why each exists
Chrome requires every permission an extension uses to be declared up front. TabNap requests six, and uses each one for exactly what it says:
storage
Save your tab list, protected sites, and savings total locally, so they survive a browser restart.
tabs
See open tabs' URLs and titles, and discard (sleep) or reload them.
sidePanel
Show the TabNap control panel in Chrome's side panel.
system.memory
Read your device's free-RAM level, to detect real memory pressure and measure real savings.
notifications
Let you know when RAM is high and which tabs just got put to sleep.
contextMenus
Add "Open Tab Manager" to the toolbar icon's right-click menu.
alarms
A once-a-minute check that wakes TabNap's background process if Chrome has paused it from inactivity, so it can't silently stop watching your memory for long.
TabNap does not request <all_urls>, host permissions, or the ability to read the content of your pages. It has no content script — it never sees what's on a page, only that a tab exists and what its URL is.
What TabNap does not do
Collect analytics or usage telemetry
Read, log, or transmit page content
Show ads or run affiliate links
Sell, rent, or share data with any third party
Require or create a user account
Use cookies or cross-site tracking
Deleting your data
Uninstall TabNap from chrome://extensions and Chrome deletes its local storage along with it — tab history, protected sites, and savings totals all go with it. To clear just the savings counter without uninstalling, use the reset button in the TabNap sidepanel.
Children's privacy
TabNap is a general-purpose browser utility, not directed at children, and collects nothing from anyone regardless of age — there is no data collection to restrict.
Changes to this policy
If TabNap's data handling ever changes, this page will be updated and the effective date above will move. Given the extension has no server to begin with, any future change of substance here would be a meaningful shift worth reading, not routine legal boilerplate.
