The short version: Most SEDX apps work entirely offline, require no account, and collect no personal data. The exceptions — apps that need an account to function — are called out explicitly below.
This Privacy Policy describes how SEDX, LLC (operating as RLTW, "we," "us," or "our") handles information in connection with the mobile applications we publish (each, an "App"). It applies to all Apps listed at our home page, including the Ranger Handbook, Cadet Handbook, Army Survival Manual, FM Library, Helicopter Pilot, the Army Branch Handbooks series, Coxswain HQ, MUTCD 11th Edition, Robert's Rules, Abrahamic Reader, Video Timer, TeamHQ, and TrackHQ.
Our reference and training Apps — including Ranger Handbook, Cadet Handbook, Army Survival Manual, FM Library, Helicopter Pilot, the Army Branch Handbooks (Infantry, Armor, Aviation, Field Artillery, Medical, Military Police, and others), Coxswain HQ, MUTCD 11th Edition, Robert's Rules, and Abrahamic Reader — are designed to work entirely offline.
For these Apps:
Video Timer records video on your device with a stopwatch overlay. To do this it requests the camera, microphone, and local storage / photo library permissions. Recorded videos are saved to your device's local storage or photo library. We do not upload, view, or have any access to your recordings.
TeamHQ is a multi-user team coordination App, so it requires an account and synchronizes data between team members through our servers. When you use TeamHQ we collect:
We use this information solely to operate the App — authenticating you, syncing data across your devices and teammates, and sending notifications you've enabled. We do not sell your data or use it for advertising. You can request deletion of your account and associated data at any time by emailing the address below.
TrackHQ is a track & field meet-management platform with live results, which requires an account and a server-side database. When you use TrackHQ we collect:
Athlete results are typically published publicly by their nature (results boards, leaderboards). Account credentials and any non-public data are kept private and used only to operate the App.
An App will only request a device permission (camera, microphone, storage, notifications, etc.) when a feature you use requires it. The permission's purpose is described above for the Apps that request any.
Our Apps are distributed through the Google Play Store and (where applicable) the Apple App Store. Those stores independently collect information about your installs, purchases, crashes, and device per their own privacy policies, which we do not control. We may receive aggregate, de-identified statistics from these stores (such as install counts and crash summaries) which are not tied to individual users.
Some Apps may use Google Play's In-App Review feature to invite you to rate the App. This is a Google-mediated interaction; we do not receive any personal information from it.
Our Apps are not directed to children under 13, and we do not knowingly collect personal information from children under 13. For Apps that require an account (TeamHQ, TrackHQ), accounts are intended for users 13 and older, or in the case of minor athletes, created and managed by an adult coach, parent, or guardian on the athlete's behalf. If you believe a child has provided us with personal information, please contact us so we can delete it.
For offline Apps, your data never leaves your device, so its security depends on your device's own protections (screen lock, OS-level encryption). For TeamHQ and TrackHQ, we use industry-standard encryption (HTTPS in transit, encrypted storage at rest) and limit access to your account data to what's necessary to operate the service. No system is perfectly secure, and we cannot guarantee absolute security.
Our reference Apps reproduce or organize unclassified, publicly available source material (U.S. Army field manuals, FAA handbooks, the FHWA MUTCD, public-domain editions of Robert's Rules of Order, and the public-domain editions of religious texts). These Apps are provided for reference and training purposes and are not affiliated with, endorsed by, or sponsored by any government agency or other rights-holder.
We may update this policy from time to time. Material changes will be reflected by an updated "Last updated" date at the top of this page. Continued use of an App after a change indicates acceptance of the revised policy.
