Zephyr Bolt
Zephyr Bolt is an offline one-touch runner game in which a clockwork courier vaults gaps and glides over hazards along a brass catwalk. This page explains what the app does and does not do with your data.
Zephyr Bolt does not collect, transmit, or share any personal information.
Information we collect
None. The game has no account, no sign-in and no contact form, and it never asks for your email, contacts or payment details. The only text you can type is an optional courier name on the profile screen, and that name stays on your device.
Data stored on your device
To make the app work, Zephyr Bolt stores the following only on your device, using the operating system's local storage:
- your courier name and badge choice, plus lifetime run count, total distance and best Perpetual Run score;
- stars, best score, best cog haul and attempt count for each stage you have played;
- your cog balance, the day you last opened the daily supply crate and how many crates you have opened;
- the workshop fittings you have bought and the commendations you have earned;
- your Controls settings (hazard tags, high contrast, reduced flash, ambient motion) and flags recording that you have seen the intro and each chapter card.
This data never leaves your device. It is not uploaded to Zephyr Bolt or to any third party. Uninstalling the app or clearing its storage deletes all of it permanently.
Permissions
The release build of Zephyr Bolt requests no permissions at all: no internet access, camera, microphone, location, contacts, photos, storage or notifications.
Network use
Zephyr Bolt is fully offline. Every stage, image and font ships inside the app. It does not contact any server, API or content delivery network, and it plays the same in airplane mode.
Third-party services
None are integrated. There is no analytics, crash-reporting, advertising, attribution or social SDK, and no in-app purchases. Apart from the Flutter framework, the app uses only open-source libraries for local storage and animation (sqflite, shared_preferences, flutter_bloc, flutter_animate, confetti, intl), none of which collect or send data.
Children's privacy
Because the game collects and transmits nothing, it is suitable for players of any age and complies with COPPA and GDPR-K by design. We do not gather personal information from children or from anyone else.
Your rights
Everything is stored locally, so it is already under your control. To erase it permanently, clear the app's storage in Android settings or uninstall the app; Android deletes its private database and settings along with it. There is no server copy to request, export or delete.
Changes to this policy
If this policy ever changes, the date at the top of this page will be revised. Material changes will be noted in the app's release notes.
