GridSumDuel
GridSumDuel is a fully offline neon disco number puzzle. This page explains what the app does and does not do with your data.
GridSumDuel does not collect, transmit, or share any personal information.
Information we collect
None. GridSumDuel has no account or sign-in and never asks for personal details. It runs entirely on your device.
Data stored on your device
To make the app work, GridSumDuel stores the following only on your device, using the operating system's local storage:
- puzzle progress and current board state
- best scores, streaks and stats
- game settings/preferences
This data never leaves your device. It is not uploaded to GridSumDuel or to any third party. Uninstalling the app or clearing its storage deletes all of it permanently.
Permissions
GridSumDuel requests no runtime permissions. It does not access your camera, microphone, location, contacts, photos, or the internet.
Network use
GridSumDuel is fully offline. It makes no network connections and talks to no servers. The only exception is the system share sheet: if you choose to share, your device hands your chosen text to the app you pick — GridSumDuel itself sends nothing.
Third-party services
None. No analytics, advertising, crash-reporting, or tracking SDKs are embedded.
Children's privacy
GridSumDuel is safe for all ages. It collects no personal data and makes no network requests, so it complies with COPPA and GDPR-K by design.
Your rights
All data stays on your device. Clear the app's data in your device settings or uninstall the app to permanently delete all progress, scores, and preferences.
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.
