These Terms of Use (“Terms”) govern your use of the mobile application Cave Mapper (the “App”). By installing or using the App, you agree to these Terms. If you do not agree, do not use the App and uninstall it.
The App helps you build three-dimensional maps of caves and underground cavities without relying on GPS while surveying. It uses Visual SLAM (ARCore visual-inertial odometry), the device camera, and onboard sensors (barometer, magnetometer, IMU). The App can collect a point cloud and a trajectory, store mapping sessions on the device, and export data to local files (including PLY, GeoJSON, CSV, LAS, and E57, depending on the version).
You must use the App only in compliance with applicable laws and only in places you are allowed to enter. You must not use the App to trespass, to map restricted sites without authorization, or for any purpose that violates property, privacy, or criminal law. You are responsible for obtaining any required permits and consents.
The App is a mapping aid, not a safety system and not a substitute for cave training, proper equipment, a survey team, or emergency services. Underground environments are hazardous. Do not rely on the App for navigation, rescue, or life-safety decisions. In an emergency, contact local emergency services.
The App may request access to the camera (required for AR tracking), location (optional start-of-session GPS fix on the surface), and motion/environment sensors. If you deny or revoke permissions, some features may be unavailable or unreliable. Location, if captured, is stored only in the local session on your device.
Mapping data is processed and stored on your device. The App is designed to work without a network connection and does not require a cloud account. You are responsible for backing up, sharing, and deleting the files you export.
Point clouds, trajectories, depth, and heading depend on lighting, camera quality, sensor hardware, magnetic anomalies, battery-saving modes, and ARCore tracking. Drift can accumulate, especially in long sessions or low light. The App is provided for informational and field-sketch purposes; we do not guarantee survey-grade accuracy, uninterrupted service, or fitness for a particular purpose.
Exported files reflect the data collected in a session, including any start GPS coordinate you allowed. Once you share a file, you control where it goes. We are not responsible for copies you send to others or store outside the App.
The App uses Google ARCore and other platform components. Their use is subject to those providers’ terms and privacy policies. AR features require a compatible device and may be unavailable if ARCore cannot run.
The App, its branding, and its content (except the mapping data you create) are protected by intellectual property laws. You receive a limited, non-exclusive, non-transferable license to use the App for personal or professional field mapping in line with these Terms. Mapping data you capture belongs to you, subject to the rights of landowners and applicable law.
To the fullest extent permitted by law, the App is provided “as is” and “as available,” without warranties of any kind, express or implied, including merchantability, accuracy, or non-infringement.
To the fullest extent permitted by law, the operator of the App is not liable for injury, getting lost, equipment damage, indirect, incidental, special, consequential, or punitive damages, or for loss of profits, data, or goodwill, arising from your use of the App, including reliance on maps, depth, or heading. Total liability for any claim related to the App is limited to the greater of (a) amounts you paid for the App in the twelve months before the claim, or (b) zero if the App was free. Some jurisdictions do not allow certain limitations; in those cases, liability is limited to the maximum permitted by law.
You agree to defend and indemnify the operator against claims arising from your misuse of the App, unauthorized entry, your violation of these Terms, or your violation of others’ rights, to the extent permitted by law.
We may modify these Terms. We will indicate an updated “Last updated” date. Continued use after changes may constitute acceptance where allowed by law. If you disagree, stop using the App and uninstall it.
Sessions, point clouds, sensor readings, and an optional start GPS coordinate are stored locally on your device. The App does not require you to create an account. Do not log or share precise coordinates if you are not allowed to disclose the location of a cave.
Unless mandatory consumer protection laws in your country require otherwise, these Terms are governed by the laws applicable to the operator’s place of establishment, without regard to conflict-of-law rules. Courts in that jurisdiction may have exclusive jurisdiction, except where consumers cannot be deprived of their statutory protections.
