About the offline game
Gravisky is an offline single-player game by Silva Studios. You do not need a Gravisky account. This release has no advertising or in-app purchases.
The game does not collect or share personal data off your device. It has no analytics, advertising, billing or remote crash-reporting service enabled. It does not ask for your name, birth date, email address, location, contacts, microphone or camera access. Optional frame-time information is shown only on your device.
Google Play and Android provide their own installation, store and device services under their own privacy practices.
Progress, backup and deletion
The game saves completed courses, your last course and layout, eligible best times, your best completed Cloud Hunt keepsake count, and control, sound and display settings in its app storage. An unfinished flight is not saved after closing the game.
Android may include this storage in device backups or transfers, depending on your settings and platform behavior. Silva Studios has no access to these backups and does not operate a game-save server. Restore is not guaranteed.
Clearing the app's storage or removing the app deletes its local records and settings. Backups may remain or restore records later; manage those copies through your device or platform's backup controls. We cannot remotely recover or delete your local progress.
Support and privacy requests
Contact support@gravisky.com for player support or privacy enquiries.
If you email us outside the game, we receive your address and the message or attachments you choose to send. We use these to answer your enquiry and resolve the issue. The game has no contact form and does not send game records to this mailbox.
Messages are handled through Google mail. Marco Da Cruz Silva is the only person at Silva Studios with access to the support mailbox. Google also processes messages to provide its email service.
You can use the same address to ask about, correct or request deletion of information you have sent us.
How long we keep messages
We delete resolved support and privacy conversations from the mailbox after three months.
If a conversation must be kept longer for an unresolved issue or a legal obligation, we keep it only for that reason and delete it when it is no longer needed. Google's service may retain separate backup or technical records under its own practices; this period does not promise deletion of every provider-held copy.
Please do not send passwords, payment details or unnecessary personal information. A parent or guardian can contact us on a child's behalf.
For records held only on your device or in Android backups, use the controls described on the progress page.
Younger players and future changes
Gravisky's design target is ages 10 and up. The offline game does not ask players for their age or require an account. This design target is separate from a content rating assigned through Google Play.
This policy covers the offline release. If payment or online features are introduced later, we will review their data practices and update this policy and the store disclosures to describe the actual release.
You can return to this policy from the course library or Pause, even without an internet connection. For questions about this policy, contact support@gravisky.com.
