What we store on your device, why, and how to change your choices
Last updated: October 28, 2026
This page lists the cookies and similar browser storage used on playversusai.com, what each one is for, and how to change your choices. It sits alongside our privacy policy, which covers personal data more broadly, and our terms of service.
A cookie is a small text file a website asks your browser to keep and send back on later visits. Local storage is a related browser feature that keeps data on your device; the site's own code can read it, but the browser does not send it to a server automatically. PlayVersusAI itself does not set any cookies of its own. Everything we store ourselves is in local storage, and the cookies you may see on this site are set by Google for its consent tool and advertising.
These are needed for features you ask for, so they do not require consent.
| Name | Type and provider | Purpose | Retention |
|---|---|---|---|
| sb-…-auth-token | Local storage, set by the Supabase login library | Keeps you signed in between pages and visits. Only created when you log in. | Until you log out or clear site data |
| FCCDCF, FCNEC | Cookies, set by Google's consent tool | Remember the privacy and cookie choices you made in the consent message so it is not shown on every page. | Set by Google, typically up to 13 months |
These remember your game data on your own device. They never leave your browser and are not shared with anyone.
| Name | Type | Purpose | Retention |
|---|---|---|---|
| pvai_best_… | Local storage | Your personal best score or time in each solo game, shown next to the board. | Until you clear site data |
| pvai_wg_state | Local storage | Today's Word Guess board, so reloading the page does not reset or restart the daily puzzle. | Replaced each day |
| pvai_wg_streak | Local storage | Your Word Guess streak. It is kept only on this device and browser. | Until you clear site data |
| pvai-show-anon | Local storage | Whether the leaderboard page includes anonymous guest results. | Until you clear site data |
We do not currently use any analytics cookies or analytics service. The site's code includes an optional Google Analytics 4 integration that is switched off. If we ever enable it, we will list its cookies here first, and visitors in the EEA, UK and Switzerland will only receive them with consent.
Advertising keeps every game free. We use Google AdSense, and Google and its partners may set or read cookies to serve ads, limit how often you see the same ad, measure ad performance, detect fraud and, depending on your region and choices, personalise ads to your interests. Examples include __gads, __gpi and __eoi on playversusai.com and IDE on doubleclick.net. These cookies are set by Google, not by us, and we cannot read their contents. Google publishes the list and lifetimes of its advertising cookies in How Google uses cookies.
Opting out of personalised advertising does not remove ads; it means the ones you see are not chosen using your browsing history. Google explains how it uses information from sites like ours at policies.google.com/technologies/partner-sites.
The Supabase code library loads from the jsDelivr content delivery network. That request reveals your IP address and browser details to jsDelivr, but it does not set cookies.
Ads currently appear only in side rails on wide desktop screens, outside the main page content. They are never placed inside a game board, never overlaid on a game in progress, and never positioned where they could be mistaken for a game control. Pages for account management, such as your profile and password reset, do not load ads. If an ad ever interferes with a game, report it via the contact page with a screenshot and we will fix it.
We use Google's consent management platform (Google Privacy & messaging, certified under the IAB Europe Transparency & Consent Framework). Visitors from the European Economic Area, the United Kingdom and Switzerland are asked for consent before advertising cookies are used. Until you choose, Google Consent Mode tells Google's tags that advertising and analytics storage are denied in those regions, so ads are not personalised and advertising cookies are not used. Strictly necessary storage does not require consent because the features you asked for cannot work without it.
You are in control, and you can play every game without accepting advertising cookies.
If we add a service that sets new cookies or stores new data on your device, we will update this page and the date at the top before it goes live. Wider changes to how we use your data are covered in the privacy policy.
