Vyuhh is a free game made by one person in India. It keeps as little about you as it can. This page says what that is, in plain words.

You can play the computer, a friend on one device, puzzles, and online games without signing in. Games you finish on this device, your settings and your puzzle progress are kept only in your browser (its local storage). They never leave your device, and clearing your browser data removes them.
For an online game as a guest, the game gives your browser a random anonymous id so the two boards can talk. The moves of online games are stored on our server so both players see the same game.
Signing in uses your email address. We use it only to send you sign-in codes. We don't send newsletters, don't share it and don't sell it, and other players can never see it.
Your profile — username, and if you choose to add them a display name, country and a short bio — is public, along with your rating, your results and the online games you have played. That is the point of a profile: other players can look you up.
Accounts and online games are stored with Supabase, the site is served by Netlify, and sign-in emails are sent by Resend. These services may store data outside India. They handle it only to run Vyuhh.
Vyuhh uses no advertising and no tracking cookies. Your browser stores a sign-in token so you stay signed in.
Play your own games. Don't use an engine or anyone else's help during a rated game, don't create extra accounts to raise a rating, and don't choose a username that is offensive or pretends to be someone else. Accounts that do may be renamed or removed.
Vyuhh is offered free and as it is. It may change, have bugs or be unavailable at times, and ratings or records may occasionally be corrected. You must be at least 13 to create an account; if you are under 18, please have a parent or guardian's permission.
