Terms

By using TerrainFold Drill, you acknowledge that it is a free educational exercise supplied as-is for basic visual practice.

No field-navigation advice

The diagrams are generic and omit scale, direction, coordinates, contour interval, route, weather, access and hazards. Do not use an exercise, explanation, score or asset to plan travel, navigate, assess terrain risk or make a safety decision. Use current authoritative maps, suitable equipment, qualified instruction and local advice.

No competence claim

A correct answer or high accuracy applies only to this simplified ten-round session. It does not certify outdoor, cartographic, rescue, surveying, military or professional competence.

Accuracy and availability

Reasonable effort is made to keep the broad classroom relationships internally consistent, but no guarantee is made that the service will remain available or error-free. Report a suspected content or accessibility issue through the public maintainer route.

Original content

The site’s code, interface copy, brand, original mathematical diagrams and generated terrain artwork may not be represented as an official product of another organization. Third-party marks remain the property of their owners; no affiliation is claimed.

Changes

The exercise and these terms may change as errors are corrected or features are narrowed. Continued use after an update means the current version governs that visit.
