Privacy Policy

Last updated: February 15, 2026

This explains what data we collect and what we do with it.

What We Collect

If you play anonymously:

• A unique ID assigned by Firebase (Google's authentication service)
• Your game stats and leaderboard position
• Analytics data through Google Analytics (pages visited, session duration, device type)
• Technical logs and "replays" if the game crashes (to help us find and fix bugs)
• Your IP address

If you create an account:

• Your email address (if you sign up with email)
• Your Google account info (if you sign up with Google)
• Your chosen username
• Everything listed above for anonymous users

If you purchase premium features:

Payment information is processed by Stripe. We don't see or store your credit card details, but Stripe does.

What We Do With It

We use this data to:

• Make the game work (authentication, saving your progress)
• Show you on the leaderboard
• Improve the game through analytics
• Process your payment if you buy premium features

Where Your Data Is Stored

Your data is stored on Google's servers in the United States via Firebase. If you're outside the US, your data is transferred internationally when you use the service.

Who We Share It With

Your data is shared with:

• Google (Firebase & Analytics) — they process authentication and analytics data
• Stripe — they process payments if you purchase premium features

We don't sell your data to anyone. We don't share it with advertisers or marketing companies.

Cookies

Google Analytics uses cookies to track your session. By using the site, you're consenting to these cookies.

Leaderboards Are Public

Your username and stats appear on public leaderboards. If you choose an identifiable username, that's on you. Default usernames are randomly generated.

Why We're Allowed To

We process your data based on:

• Contract performance — running the game, saving your progress, processing purchases
• Legitimate interest — analytics to improve the game, preventing cheating
• Consent — when you create an account or make a purchase

How Long We Keep It

We keep your account data until you delete your account. Google Analytics data is retained according to Google's default retention periods (typically 14–26 months).

If you delete your account, all your data goes with it.

Your Rights

You can:

• Request deletion of your account and all associated data
• Request a copy of your data
• Request correction of inaccurate data

To exercise any of these rights, email us at support@blackjacksmack.com.

Kids

You must be at least 13 to create an account. If you're under 13, don't give us your email address. You can still play anonymously.

Changes

We might update this policy. If we make significant changes, we'll update the date at the top.
