Terms of Use

Effective 22 August 2026 · How the application may be used. These rules sit alongside the Terms & Conditions; where the two speak to the same point, the Terms & Conditions prevail.

1. Use it for planning, not for authorisation

ReliefMapper draws areas and divides them into sectors. It does not know your airspace, your permissions, your aircraft, the weather or the people on the ground.

Operational responsibility stays with you.
  Before any flight, the operator and the pilot in command remain responsible for
  airspace and authorisation checks, for ground risk, for the accuracy of the area
  flown, and for compliance with the rules of the country of operation. A sector grid is
  a plan, never a clearance.

2. What you may do

Use the tool for your own operations, professional or personal, including commercial work.
Export your areas and sectors, and use those files in any flight-planning software you like.
Install the application on your device and use it offline.
Share the exports with your own team, clients or authorities.

3. What you may not do

Attempt to break, overload or probe the site, the API or the accounts of others.
Automate the interface to generate requests at machine scale, or resell access to it as if it were your own service.
Copy the application to pass it off as your own product, or remove the marks that identify it.
Use it to plan anything unlawful, or in a way that would put people at risk.
Upload or paste content you have no right to use.

4. Fair use of the map services

The map and the place search are public services of the OpenStreetMap Foundation, provided free of charge to everybody. They are not ours, and they are not unlimited. Use them as a person uses a map: pan, zoom and search at human pace. Do not script bulk searches, do not scrape tiles, and respect the tile usage policy and the Nominatim usage policy. Abuse of these services can get an entire application blocked — for everyone using it.

5. Your account and your storage

When you connect Microsoft OneDrive or Google Drive, the application writes only to the folder it creates for your projects, using the access your provider grants it. Keep your provider account secure; sign out on shared devices. If you believe your account has been misused, tell us at innovations@onesevenoh.com.

6. Offline copies

The application can be installed and will keep working without a connection, using the parts already stored on your device — including map tiles you have already viewed. An offline copy is a snapshot: areas outside the tiles you have seen will not appear until you are online again, and an offline copy may be older than the live version until it updates itself.

7. If these rules are broken

We may restrict or end access, as set out in section 7 of the Terms & Conditions. We would rather write to you first, and in nearly every case we will.
