Privacy policy

Last updated 8 June 2026 · J&B Creations

Hueline is a daily color puzzle. We designed it to need as little of your data as possible. This policy explains what the app touches and why.

What stays on your device

  • Your play history, streak, and The Mosaic (daily results, scores, stats) are stored locally on your device with Apple's SwiftData, and shared with your Apple Watch and widgets through a private App Group container. We don't have a server and we never see it.
  • Your settings (reminder time, sound, haptics, accessibility options) are stored locally.

What we don't collect

  • No account, no sign-in, no email required.
  • No contacts, photos, location, or health data.
  • We do not sell your data. Ever.

Optional analytics

If enabled, Hueline uses PostHog to record anonymous, aggregate product events (for example, "a round was completed" or "the paywall was shown") to understand how the app is used. These events are not tied to your identity.

Advertising

The free tier shows occasional ads via Google AdMob (a single post-session interstitial and an optional rewarded video for hints, no banners). Before any ad measurement that involves tracking, iOS will ask for your permission (App Tracking Transparency). Hueline plays exactly the same whether you allow tracking or not. Hueline Pro removes ads entirely.

Purchases

Hueline Pro (subscriptions and the lifetime unlock) is processed by Apple through the App Store. We use RevenueCat to manage subscription status; it receives an anonymous app user ID and your purchase receipt to unlock features, not your name or payment details. Apple handles all payment and billing.

Game Center

If you choose to sign in to Apple Game Center, leaderboards and achievements are handled by Apple under Apple's privacy policy. Game Center is entirely optional; Hueline plays fully without it.

Notifications

If you turn on the daily reminder, Hueline schedules a local notification on your device. No reminder data leaves your device.

Children

Hueline is suitable for all ages and collects no personal information.

Your choices

  • Turn ad-related tracking off by declining the App Tracking Transparency prompt (or in Settings, then Privacy & Security, then Tracking).
  • Delete all local data by deleting the app.
