Last updated September 26, 2026 · Version 1.0

Your puzzles.
Your progress.

One Line does not require an account, display ads, track you across apps, or send gameplay analytics to Colorblast LLC.

Progress and preferences

The app stores completed puzzles, ongoing attempts, hint and tap counts, streaks, unlocked worlds and settings locally on your device. These records make resume, scoring and personalization work. If iCloud is enabled, the app also uses Apple's iCloud key-value storage to sync progress and settings between devices signed in to your Apple Account. Colorblast does not operate a gameplay server or receive this save data.

Purchases

Apple processes the optional one-time unlock through the App Store. The app checks Apple's signed purchase status to provide access and restore purchases. We do not receive your card or bank details. Apple's own data handling is covered by Apple's Privacy Policy.

Reminders and sharing

If you choose a daily reminder, the app asks for notification permission and schedules local notifications. It does not use a remote push-notification service. Sharing a puzzle result opens the iOS share sheet; nothing is sent until you choose a destination and complete the action.

Analytics and permissions

Version 1.0 does not enable third-party analytics or advertising. One Line does not request your location, contacts, photos, microphone or camera. Diagnostic information you choose to share with Apple is governed by your device settings and Apple's policies.

Your choices

You can change the reminder time and switch off sounds and haptics in the app. Use Manage notification permission in the app to open iOS Settings and turn reminders on or off. Manage iCloud access in your device's Apple Account settings. Removing the app deletes its local data, but an iCloud copy may remain and restore after reinstalling; manage that copy through Apple's iCloud storage controls. There is no separate One Line account to delete.

Support

If you email us, we receive the email address, message and attachments you choose to provide and use them to respond to your request. Do not include passwords or payment details. For support or privacy questions, contact hello@getghar.com and mention One Line.
