Privacy policy

Cold Case Files is a free side project run by Kishan Bisoyi in Berlin, Germany. This page explains what information the game keeps about you and why. The short version: only what it needs to save your progress and show the leaderboard. No ads, no tracking, and nothing is sold.

What we collect

• From your Google account, when you sign in: your email address, name and profile picture link. They identify your account. Your email and name are never shown to other players.
• Your detective name: the username you choose. It appears publicly on leaderboards.
• Your game activity: cases you open, notes, hints used, guesses and scores, so you can resume a case and earn points.

We don't ask for, and don't receive, your Google password or access to your Gmail, contacts or files.

Cookies

The game uses cookies only to keep you signed in. There are no advertising or analytics cookies, so there's no cookie banner.

Who processes your data

• Supabase stores accounts and game data, on servers in the EU (Ireland).
• Vercel hosts the website.
• Google handles signing in.

Each one processes data only to provide its service to this game.

Why we use it

To provide the game you signed up for: saving your progress, scoring your solves and showing leaderboards (under the GDPR, this is processing necessary to provide the service you asked for).

How long we keep it

For as long as you have an account. If you ask us to delete your account, your data is removed within 30 days.

Your rights

You can ask to see, correct, export or delete your data at any time. Email hello@kishanbisoyi.com from the address you signed in with. If you're in the EU, you can also complain to your local data protection authority.

Changes

If this policy changes in a meaningful way, the date at the top will change and the game will say so.
