Cookie policy
LAST UPDATED · 8 MAY 2026
Lexica uses a small number of cookies and pieces of browser storage to make the service work. This page lists each one, what it's for, and how long it lasts. The free game at the root of the site is covered by the main cookie policy.
How we categorise them
Under UK PECR and the ICO's guidance, we split cookies into two groups:
- Strictly necessary — needed to deliver something you've actively asked for (signing in, joining a tournament, paying). These don't require consent.
- Optional — anything else, like analytics. We only set these after you've consented via the cookie banner.
Strictly necessary
| Name | Purpose | Type | Duration |
|---|---|---|---|
vm-lexica-client-id | Recognises you on return visits to a tournament so you keep your username and score. | First-party cookie | 1 year |
vm-username | Remembers the last username you used so you don't have to type it again. | First-party localStorage | Until you clear it |
vm-lexica-tournaments | A list of tournaments you've joined, so they appear on the landing page for easy return. | First-party localStorage | Until you clear it |
__clerk_*, __session | Sign-in session for organisers. Set by Clerk, our authentication provider. | Third-party cookies (Clerk) | Up to 30 days |
__stripe_* | Set by Stripe during checkout to prevent fraud and complete payment. | Third-party cookies (Stripe) | Up to 1 year |
vm-cookie-consent | Records your choice on the cookie banner. | First-party localStorage | Until you clear it |
Optional (consent required)
| Name | Purpose | Type | Duration |
|---|---|---|---|
_ga, _ga_* | Google Analytics — anonymous usage stats so we know what to improve. | Third-party cookies (Google) | Up to 2 years |
| Vercel Analytics | Page-view counts and basic performance metrics, no personal identifiers. | First-party | Per visit |
We don't set any of the optional ones until you accept them on the banner. If you accept, you can change your mind any time on the main cookie page.
How to control cookies
- Use the cookie banner on first visit, or revisit the cookie page to change your mind.
- Most browsers let you block or delete cookies through their settings. Blocking strictly necessary cookies will break sign-in, payments, and roster recognition.
Updates
If we add or change cookies in a way that affects you, we'll update this page and, if appropriate, re-prompt for consent.
