Privacy

Effective date: November 12, 2026

GridClash shows no ads and doesn't sell your information. This page describes what it keeps and why.

If you have an account

Your email address and username. Your password is handled by our sign-in service and stored in hashed form, not as readable text.
Your games: daily grid runs (answers, points and time), head to head matches, chat messages and reactions, and the players you've used.

If you play without an account

Your daily grid runs are kept in your browser. The names you played are also sent to the server with a random run id, and nothing about you.
Head to head gives you an anonymous identity so the match knows whose turn it is. Your match, the name you chose and your chat are kept like any other match. If you create an account later, your matches move to it.

Visits

The site keeps its own record of visits. It does not record names, emails or IP addresses with it. A random visitor id, kept in a cookie and replaced every day, is sent with:

which GridClash site and pages you open, and when
where your visit came from (for example a search engine, or a shared link)
your approximate city, region and country, which the site's host works out from your connection (your IP address itself is not stored)
your browser, operating system, whether you're on a phone, tablet or computer, your browser's time zone, and the phone's maker and model when your browser shares them
whether you touched, typed or scrolled on the page (to tell people from automated visits)
what you did, with the time: started or finished a daily grid (with its score), practiced, answered right or wrong, created or joined a match, shared a result, created an account or signed in

This record is kept with no end date. The visitor id is replaced every day, so the record doesn't carry one id from one day to the next.

What other players see

Your username and daily scores on the leaderboard. Players who have finished today's grid can open yours.
In head to head, your opponent sees your name, moves and chat.

Cookies and browser storage

GridClash uses a few cookies and your browser's storage for: keeping you signed in, the daily visitor id, noting where a visit came from (until you close the browser), guest daily runs, and settings such as sound. GridClash shows no ads and sets no advertising cookies.

Who else is involved

Supabase runs the database and sign-in. Its sign-in service records the IP address and browser each time an account signs in.
Vercel hosts the site and may keep standard server logs, including IP addresses.
Fonts come from Google Fonts, and team logos and player photos load from the leagues' own websites. Like any web request, these see your IP address.
The database is backed up every night, and each backup is kept for 30 days.

Your choices

Your account and games are kept until you ask for them to be deleted. You can change your username at any time from your account menu. To delete your account and its data, or to ask what's kept about you, email hello@gridclash.app.

Age

GridClash is meant for people 13 and older.

Your rights where you live

Depending on where you live and which laws apply, you may have rights concerning your personal information. To make a privacy request, contact hello@gridclash.app.
