Cookie policy
This page tells you what PHIEZ uses cookies and browser storage for, and how you can turn them off or delete them. The site shows Google AdSense ads, so Google and advertising partners may place cookies on your device.
Updated: October 21, 2026
1. What are cookies?
Cookies are small text files a website saves on your device. Besides cookies, browsers have similar stores such as Local Storage or IndexedDB. On this page we call them all "cookies and local storage".
2. What we use
Below are all the groups of local data that PHIEZ uses:
Local Storage — settings, results, history, favorites, mini game records, draw tool data
Remembers your settings and progress right on your device.
Provided by: PHIEZ
Cookies _ga, _ga_*
Tells anonymous visits apart so we can count page views.
Provided by: Google Analytics
Advertising cookies (for example IDE, __gads, __gpi)
Show ads, limit how often an ad appears, measure ad performance and prevent ad fraud. May be used to personalize ads if you allow it.
Provided by: Google AdSense and advertising partners
Sign-in storage (Local Storage / IndexedDB)
Keeps you signed in so you do not have to sign in every time. Only present when you sign in.
Provided by: Firebase Authentication
3. What we do not do
- We do not sell your cookie data or personal data to anyone.
- We do not pass your name, email or quiz results to advertisers.
- We do not install any other tracking tools beyond those listed above.
4. Advertising cookies (Google AdSense)
Google and its partners use advertising cookies to show ads based on your visits to this site and other sites. Cookies also help limit how many times you see an ad, measure performance and detect fraud.
- Turn off personalized ads at adssettings.google.com.
- Opt out of cookies from other ad providers at aboutads.info/choices.
- See how Google uses cookies at policies.google.com/technologies/cookies.
- Users in the European Economic Area, the United Kingdom and Switzerland will be asked about advertising cookies through a notice on the site, and can change their choice at any time.
5. Analytics cookies (Google Analytics)
PHIEZ uses Google Analytics to learn which pages are viewed and which devices and browsers are common, so we can improve content and interface. The data is aggregated and not used to identify you personally.
You can opt out by blocking cookies in your browser or by installing the Google Analytics opt-out add-on provided by Google. The site still works normally if you do.
6. Managing and deleting
- Open your browser's privacy settings to block or delete cookies and site data.
- Deleting the data of PHIEZ removes the settings, quiz history and game records stored on your device (scores synced when signed in remain on your account).
- Blocking advertising cookies does not remove ads; it only makes them less relevant to you.
- Blocking Local Storage may stop some features from saving your progress.
7. Changes to this policy & contact
When our use of cookies changes, we will update this page and show the update date at the start of the page. See how we handle data in the Privacy policy.
