CHAIN DUEL · iPhone · iPad
Privacy Policy
Effective October 8, 2026. This policy explains privacy when you use CHAIN DUEL.
Offline play
CHAIN DUEL works offline and does not require an account. The game contains no advertising, analytics tools, user tracking or in-app purchases. We do not collect or receive personal data from the game.
Settings and progress
Your language, audio settings, tournament progress, scores, trophies and completed training challenges are saved locally on your device using system preferences. The game does not send this information to us or to an external server.
Storage and deletion
Local data remains available between play sessions. Deleting the app removes its local data from your device. System backups and their restoration depend on your device settings and Apple's policies.
Music credit links
The music credits include links to the recordings' source pages and licenses. Selecting a link opens an external website in your browser. Its operator may process data under its own privacy policy; the game does not receive information about your browsing.
Apple services
App Store downloads, app updates and your device's system services are subject to Apple's policies. Data processed by Apple as part of these services is not collected by the game.
Policy updates
If the game's privacy practices change, we will update this policy and its effective date. The full policy is also available in the app without an internet connection.
Contacting support
If you choose to send a support email, Łukasz Pociask will receive your email address and message to handle your request. This is voluntary correspondence outside the game, not automatic data collection by the app. You can send requests concerning that correspondence to the same address.
Contact
A question or bug? Contact Łukasz Pociask. Include your device model, iOS/iPadOS and game version, and a short description. Do not send passwords or other confidential data.
