Colorflow is a small, independent puzzle game. We collect as little information as possible — only what's needed to power the game's online features and to serve ads. We do not sell your data, share it for marketing, or track you across other apps and websites.

What we collect

When you play Colorflow, we collect:

• A username you choose — used to display you on leaderboards and the Daily Challenge.
• A randomly generated device ID — used to associate gameplay progress with your device. This is not your Apple ID, name, or email.
• Gameplay data — levels completed, daily challenge times, achievements unlocked, in-game coins, and similar progress. Used to power leaderboards, achievements, and to restore your progress if you reinstall.

We do not collect your email address, real name, phone number, contacts, photos, precise location, or payment information. Purchases are handled entirely by Apple — we never see your payment details.

Ads (AdMob)

Colorflow shows optional rewarded video ads served by Google AdMob. When an ad is shown, AdMob may collect:

• Your device's advertising identifier (IDFA on iOS, AAID on Android)
• IP address and approximate location (country/region level)
• Device type and OS version
• Ad interaction data (whether an ad was viewed, tapped, or completed)

This data is collected by Google, not by us. You can limit ad tracking at any time:

• iOS: Settings → Privacy & Security → Tracking → turn off "Allow Apps to Request to Track"
• Android: Settings → Google → Ads → "Delete advertising ID"

How we store data

Gameplay data and your username are stored on Convex, our backend provider. Data is transmitted over HTTPS and stored on Convex's servers in the United States. See Convex's privacy practices: https://www.convex.dev/legal/privacy
