Install the Extension

Three steps to take control of your ad profile. Works on Chrome, Edge, Brave, and any Chromium browser.

1

Build your ad profile

Head to the profile builder and pick the topics you care about. Set percentage weights for each. When you save, you'll get a profile token — copy it.

Your profile token looks like: a3f8c2e1...b9d4. It's how the extension knows what cookies to inject.

2

Load the extension

Until we're on the Chrome Web Store, install manually:

↓ Download adtune-extension.zip
  1. Unzip the downloaded file anywhere on your computer
  2. Open chrome://extensions in your browser
  3. Enable Developer mode (top-right toggle)
  4. Click Load unpacked and select the unzipped extension/ folder

You'll see the AdTune icon appear in your toolbar.

3

Connect your profile

Click the AdTune icon in your toolbar, paste your profile token, and hit Connect. The engine will immediately:

  • Purge tracking cookies from 40+ ad networks
  • Inject interest-signaling cookies matching your profile
  • Schedule automatic refreshes (every 6 hours by default)

That's it. Your ad profile is now yours.

Questions

What tracking cookies does it delete?

AdTune targets cookies from 40+ ad-tech domains including Google DoubleClick, Facebook, The Trade Desk, Criteo, AppNexus/Xandr, PubMatic, Oracle BlueKai, Adobe Audience Manager, and more. It also recognizes tracking cookie patterns like _ga, _fbp, and UUID-based identifiers.

How does the injection work?

The extension sets cookies on ad-tech domains with encoded values representing your chosen interests (IAB categories, Google Topics, DV360 audiences). When these domains are contacted during ad auctions, they read the cookie data and serve ads matching your profile instead of their surveillance-built one.

How often does it refresh?

By default, every 6 hours. You can change this to anywhere from 30 minutes to 24 hours in the extension settings. It also runs automatically when you open your browser.

Does it work with ad blockers?

Yes. AdTune doesn't block ads — it reshapes which ads you see. If you have an ad blocker, AdTune still cleans tracking cookies. If you whitelist certain sites, AdTune ensures the ads you see there match your interests.

What permissions does it need?

The extension requires cookies (to read/write/delete cookies), alarms (for scheduled refreshes), and storage (to save your settings). It also needs host permissions for ad-tech domains to manage cookies on those domains.
