Understand ads, locked options and Premium

Preview before applying

Concentric Clock lets you preview locked options. A preview does not mean the option has been unlocked or applied. Look at the lock indicators and any confirmation before continuing.

Optional rewarded unlocks

Selected colour accents, presets and Fast ticking offer a rewarded ad when available.

1. Choose an option that offers a rewarded unlock.
2. Read the confirmation and continue only if you want to watch the ad.
3. Complete the ad’s reward requirement. Leaving before the reward is earned, cancellation or a failed ad does not grant a reward.
4. Wait for the ad to close and check that the chosen option was applied.

Keep local rewards

Rewards belong to the current app installation. Uninstalling Concentric Clock or clearing its app data removes them. Do not clear storage as a routine fix for a widget problem. An ad may be unavailable because of connectivity, privacy choices or ad availability; no unlock is applied when an ad cannot be shown.

Premium faces and privacy choices

Some clock faces require Premium access rather than a rewarded ad. Premium purchasing is not available in the current development build. Do not treat preview access or an informational price as a completed purchase. Where the app provides Ad privacy choices in Settings, use it to review the available choices. The privacy page explains advertising services and related data handling.
