Privacy Policy

Last updated: September 30, 2026

TL;DR: The CacheSweeper extension doesn't send your browsing history, page contents or cleared data to us or anyone else. All of its clearing happens locally, in your browser. If you buy Premium, it keeps your license key in your browser and sends it to Lemon Squeezy to confirm it. Version 1.0 also saved its settings, including any site names you typed into them, with Chrome sync (see below). The extension has no accounts, no tracking and no analytics. This website uses Google Analytics and Google Ads only if you allow them; see Cookies and this website.

What CacheSweeper does

CacheSweeper is a Chrome extension that clears browser storage (HTTP cache, cookies, localStorage, sessionStorage, IndexedDB, CacheStorage, and related data) when you click the toolbar icon or press the keyboard shortcut. If you switch them on, it can also clear browsing history, download history, and autofill form data; those toggles are off by default, and passwords are never touched. All clearing operations run locally through Chrome's built-in APIs. Nothing you browse, type into websites, or store there leaves your machine through CacheSweeper. If you buy Premium, it sends your license key to confirm it, described below.

Data the extension doesn't collect

  • No browsing history or page content ever leaves your browser
  • No keystrokes, form data, or passwords
  • No analytics, telemetry, or usage tracking inside the extension
  • No personal information. The free tier doesn't even have a concept of an account

Data stored locally

Your profiles and preferences (which storage types to clear, auto-reload settings, and so on) are saved with Chrome's chrome.storage API, along with the numbers behind the Metrics tab (how many clears, how much space was freed, cookies removed). This data lives in your browser. From version 1.0.1 it stays in this browser and is not synced. Version 1.0 saved your profiles and preferences with Chrome's built-in sync, so if you have Chrome sync on, Google may keep and sync the copy 1.0 saved across your devices under Google's privacy policy (opens in a new tab); 1.0.1 reads that copy once, to move your settings into this browser. That's between you and Google; we never see it.

Two things are handled only for as long as they are needed, and never stored on disk or sent anywhere. While Chrome is open, the extension keeps a list of the site addresses your tabs have visited (the origin only, such as https://example.com) in Chrome's session storage, which Chrome discards when it closes; it uses the list to honour protected domains and tab-close clearing. And when it clears localStorage, it briefly copies the page's sessionStorage and puts it straight back, because Chrome's localStorage removal would otherwise wipe sessionStorage in your open tabs.

If you purchase Premium, your license key is stored locally in that browser only (it is not synced). To activate it, and afterwards to confirm it is still valid (about once a day, and when you open the settings page, at most once an hour), the extension sends the key and an activation ID to Lemon Squeezy's license service. Nothing else goes with it: no browsing data, no settings, no identifiers from your machine beyond a label such as "Chrome on Windows".

Version 1.0's settings page loads its fonts from Google Fonts and its icons from the jsDelivr CDN, which shows your IP address and user agent to those services when you open it. From version 1.0.1 both ship inside the extension.

Premium payments

Premium purchases are processed by Lemon Squeezy (opens in a new tab), our merchant of record. When you buy, Lemon Squeezy collects the information needed to complete the transaction (your name, email address, billing details, and payment method) and handles VAT and receipts. Their handling of your data is described in the Lemon Squeezy privacy policy (opens in a new tab).

From that transaction, we receive only your email address and license information, which we use solely to deliver and validate your license and to provide support.

Cookies and this website

This site is served through Cloudflare, which processes visitor IP addresses to deliver and protect the site (see the Cloudflare privacy policy (opens in a new tab)). It uses Cloudflare Web Analytics, a cookieless, aggregate measurement of page views and load performance that sets no cookies, keeps no client-side identifiers, and does not track you across sites. The site loads fonts from Google Fonts and icons from the jsDelivr CDN. Those requests expose your IP address and user agent to the respective CDN, as with any site using them.

The Google tools below are optional and stay off until you allow them. A card asks on your first visit, and the Cookie settings button in the footer of every page brings it back, so you can change your mind at any time. Your choice is saved in this browser's local storage (as cs-consent) for 180 days; after that, or sooner if the choices themselves change, we ask again.

  • Site improvement (Google Analytics). Shows us which pages and guides people read, whether they scroll most of the way down, and which links out of the site they click, such as Add to Chrome, the pricing buttons and the support email link. We use it to decide what to improve, and we have set Google Analytics to keep this data for 14 months.
  • Ad performance (Google Ads). Lets Google Ads tell us when a visit, or a click on Add to Chrome, came from one of our ads, so we can stop paying for ads that don't work.
  • Reminder ads (Google Ads). Lets Google show you CacheSweeper ads on other websites, YouTube and Google Search after your visit. Third-party vendors, including Google, use cookies to serve these ads based on your earlier visits to this site. It only works with Ad performance on, so switching it on switches that on too.

Google Tag Manager loads these tools, and only after you allow at least one of them. What Google does with the data is described in How Google uses information from sites or apps that use our services (opens in a new tab).

With your permission, these tools store the following in your browser for cachesweeper.com:

  • _ga and _ga_JNGT2RKD1F: Google Analytics cookies, kept for up to two years (Chrome limits cookies to 400 days).
  • _gcl_au: a Google Ads cookie, kept for 90 days. If you arrive by clicking one of our ads, Google Ads may add _gcl_aw, _gcl_gs or _gcl_ag, also for 90 days.
  • _gcl_ls: a Google Ads entry in local storage.

Switching Site improvement or Ad performance off deletes the entries above that belong to it, and the page reloads so the tool stops running. Google also sets cookies on its own domains, such as IDE on doubleclick.net (see Google's list of advertising cookies (opens in a new tab)). This site can't delete those: they last until they expire or you clear them in your browser. Google's My Ad Center (opens in a new tab) lets you switch off personalized ads from Google.

You can also opt out with Google directly: the Google Analytics opt-out add-on (opens in a new tab) is a browser extension from Google that stops Google Analytics collecting your visits, and the Network Advertising Initiative's opt-out page (opens in a new tab) covers other advertising companies.

None of this applies to the extension. It contains no analytics and no advertising code, and it never contacts Google Analytics or Google Ads.

Permissions, explained

Core

browsingData

The clearing engine. This is the Chrome API that deletes cache, cookies, and storage.

Core

All URLs & scripting

Lets the extension run a small script in the site's tabs to show the clear summary, ask the optional confirmation, measure how much storage a clear freed, and clear or preserve sessionStorage (Chrome's clearing API cannot reach it). It never reads page content, and nothing is sent anywhere.

Core

tabs

Reads the current tab's address to scope a clear to that site and pick the right profile, finds the site's other open tabs for sessionStorage, and notices when a tab closes for tab-close clearing.

Core

activeTab

Keeps the toolbar icon, shortcut and right-click menu working on the current tab if you limit CacheSweeper's site access to "On click".

Core

notifications

Shows a system notification after a scheduled clear, or when a clear cannot run on the current page.

Core

contextMenus

The right-click menu on the toolbar icon: clear now, switch profiles, open settings.

Core

storage

Saves your profiles and preferences locally.

Premium

alarms

Runs scheduled clears on the timer you set, and re-checks a Premium license about once a day.

Premium

idle

Lets the extension clear when your computer goes idle, if you enable that option.

Core

cookies

Counts how many cookies a clear removes so the clear summary and metrics can show it. Counts only; cookie values are never used, stored, or sent.

If a permission isn't needed for clearing, we don't request it.

Changes to this policy

If this policy changes, we'll update the date at the top of this page. Material changes will also be noted in the extension's release notes.
