By downloading, installing, or using Red Grid Link ("the App"), you agree to be bound by these Terms of Use. If you do not agree to these terms, do not use the App.
Red Grid Link is designed for personal and team coordination use in outdoor activities including search & rescue, backcountry navigation, hunting, and training exercises. The App is provided as a coordination tool, not a safety device.
You may not use this App for any unlawful purpose or in any way that could damage, disable, or impair the App.
Red Grid Link is offline-first. No user data is collected, transmitted to, or stored on any external server. All position data, session data, and configuration remain on your device.
Field Link peer-to-peer communication occurs directly between devices via Bluetooth and WiFi Direct. Position data shared during a session is encrypted with AES-256 and is not retained after the session ends on peer devices.
The Field Link feature uses Bluetooth Low Energy and WiFi Direct for peer-to-peer communication. Actual range depends on terrain, vegetation, weather, and device hardware.
Field Link is not a substitute for proper communication equipment (radios, satellite communicators). Do not rely on Field Link for life-safety communications.
Certain features require a paid subscription or one-time purchase. Subscriptions auto-renew unless cancelled at least 24 hours before the end of the current period. Payment will be charged to your Apple ID or Google Play account at confirmation of purchase.
Subscription management and cancellation are handled through your device's account settings (Settings > Apple ID > Subscriptions on iOS, or Google Play > Subscriptions on Android). Refund policies are subject to the respective store policies.
THE APP IS PROVIDED "AS IS" WITHOUT WARRANTIES OF ANY KIND. GPS accuracy, MGRS coordinate accuracy, and connectivity are subject to device hardware, environmental conditions, and other factors outside our control.
We do not warrant that the App will be uninterrupted, error-free, or that coordinates will be accurate to any particular precision.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE DEVELOPERS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES ARISING FROM USE OF THE APP.
Always carry proper navigation equipment including compass, paper maps, and backup communication devices.
We reserve the right to modify these terms at any time. Continued use of the App after changes constitutes acceptance of the new terms.
