Cookie Policy
Last updated: October 26, 2026
This policy explains the cookies and similar technologies Highlights uses on highlights.ai and in the Highlights apps, and how you can control them. These technologies let us, or the providers we work with, store or read information on your device (for example in a cookie or in local storage) or run code there (for example a script). We call them all "trackers" below, and say "cookies" only when we mean browser cookies.
Some trackers are ours ("first-party"); others enable services from third parties ("third-party"), who can access the trackers they manage. How long a tracker lasts is set by us or by its provider, and some expire when you close your browser. The providers' privacy policies, linked from our Privacy Policy, have more detail, or you can ask us.

Google Analytics 4 is a web analytics service from Google LLC. Google uses the data to track and examine use of highlights.ai, prepare reports on it and share them with other Google services, and may use it to contextualize and personalize ads in its own advertising network. IP addresses are used at collection time and discarded before data is logged. See Google's privacy policy and the opt-out add-on.
Advertising measurement
_fbp,_fbc- Tells us which Meta ads led to visits and purchases on highlights.ai (
_fbconly after a click on a Meta ad). - Set by the Meta Pixel · Lasts 90 days
Meta may also use this data under its own privacy policy. Google Analytics, above, also measures our ads.
Google Analytics and the Meta Pixel don't load when your browser sends a Global Privacy Control or Do Not Track signal, or after you opt out on Your Privacy Choices.
How to control trackers
- Opt out on Your Privacy Choices. Google Analytics and the Meta Pixel stop loading on highlights.ai in that browser.
- Send a privacy signal. Turn on Global Privacy Control or Do Not Track in your browser, and Google Analytics and the Meta Pixel won't load on highlights.ai.
- Browser settings. Block or delete cookies and other stored data in your browser: Chrome, Firefox, Safari, Edge. Deleting your browsing history also clears other trackers your browser stores.
- Device settings. On phones and tablets, you can limit some trackers in your device's advertising and tracking settings.
- Provider opt-outs. Use the Google Analytics opt-out add-on, the choices described in each provider's privacy policy, or contact the provider.
You're free to decide which trackers to allow. If you block the ones needed to run Highlights, signing in and checkout won't work.

We can't fully control third-party trackers, so what this page says about them is indicative; their providers' privacy policies have the complete information. If you'd like to know more about how Highlights uses these technologies, contact us.
