Terms of Use

Effective November 9, 2026.

These terms cover your use of the Mapsheet app and of the optional online features described below. Apple's Standard Licensed Application End User License Agreement governs your licence to the app itself; these terms add to it. If they conflict, Apple's agreement wins for the licence and these terms win for the map data and online features.

Mapsheet is a map viewer

Mapsheet shows the position your device reports on maps you choose. It doesn't make, check or update maps. GPS accuracy depends on your device, the sky and the terrain, and phones fail, run out of power and lose signal. Don't rely on Mapsheet, any one device or any one map for safety, navigation in hazardous conditions, boundary determinations or emergencies. Carry a backup, check maps against the ground, and follow the instructions of the authorities in charge (for example on a fire).

Maps and data from others

Maps you import, maps in the free map list, maps reached through links and QR codes, and aerial and topographic map downloads come from public agencies and other third parties (for example the U.S. Geological Survey, the USDA Forest Service, Natural Resources Canada, NSW Spatial Services, the Queensland Government, Land Information New Zealand, and incident teams posting to the national fire file share). They are provided "as is", without warranties of any kind, and may be out of date, inaccurate or incomplete. Their publishers' own terms and licences apply, and the credit each requires is shown in the app.

These sources can change, move, stop, or start charging at any time, and Mapsheet may add or remove them. Maps you've already downloaded stay on your device. Mapsheet doesn't promise that any source, list or download will be available.

Optional online features

Mapsheet's free map list and its imagery service for New Zealand run on Mapsheet's own server. They're free extras offered without any service level: they may be slow, unavailable or discontinued. The core app (your maps, GPS, points, tracks, measuring and crew packs) doesn't need them.

Fire information

Fire perimeters, incidents and hotspots in Mapsheet are copied from public agency feeds (NIFC/WFIGS, NASA FIRMS, Natural Resources Canada's CWFIS, the BC Wildfire Service, the NSW Rural Fire Service and the Queensland Fire Department) and can be hours old, incomplete, estimated or wrong. A satellite hotspot is a heat detection, not a confirmed fire, and a missing fire doesn't mean there is none. Fire information in Mapsheet is not a warning service and must never be used for evacuation, safety or tactical decisions: follow official warnings, your incident's briefings and the authorities in charge.

Crew nearby

Crew nearby shows where crew members' phones last reported themselves, when they're in range and sharing. Positions can be late, wrong or missing: phones move out of range, lose power or stop sharing without warning. It is not a personnel accountability, tracking or emergency locator system; keep your organization's own check-ins and radio procedures. Share positions only with people who agree to it.

Exported maps

A map you export as a geospatial PDF carries its original publisher's terms and credit, and the points, lines and areas you drew on it are yours. Check the placement in your GIS before relying on it for measurement.

Your responsibilities

• Use maps you have the right to use and share, and follow their licences.
• Follow the law where you use Mapsheet, including rules on land access and private property.
• Don't use the online features to download in bulk, resell data, or overload Mapsheet's or anyone else's servers.

Subscriptions

Mapsheet Field and Mapsheet Crew are auto-renewing subscriptions sold and billed by Apple. Manage or cancel them in Settings › Apple Account › Subscriptions; refunds are handled by Apple. Organizations can buy Crew for their people through Apple Business Manager. If a plan ends, you keep every map; you just can't add more than the free plan allows.

Limitation of liability

To the fullest extent the law allows, Mapsheet and its developer are not liable for any loss, injury, damage or cost arising from the use of, reliance on, or inability to use the app, any map, any position shown, or any online feature, including indirect, incidental or consequential damages. Where liability can't be excluded, it is limited to the amount you paid for Mapsheet in the twelve months before the claim. Some places don't allow these limits, so they may not all apply to you; nothing here takes away rights you have under consumer law.

Trademarks

GeoPDF is a registered trademark of TerraGo Technologies. Avenza is a trademark of its owner. Mapsheet is not affiliated with TerraGo, Avenza, Blue Marble Geographics, Esri, the USGS, the USDA Forest Service, NRCan, LINZ or any agency whose maps it can open.

Changes and contact

We may update these terms; the date above shows the latest version, and continuing to use Mapsheet means accepting it. Questions: laddothis at gmail dot com.
