Effective date: September 16, 2026
These Terms of Use (“Terms”) govern your use of Map Area Calculator, shown on your home screen as “Map Area Calc” (“the App”), developed by Tigran Barseghyan (“we”, “us”). By downloading or using the App you agree to these Terms. If you do not agree, do not use the App.
We grant you a personal, non-exclusive, non-transferable, revocable license to use the App on Apple devices that you own or control, in accordance with these Terms and Apple’s Media Services Terms and Conditions. Files you export from the App are yours to use as you wish, subject to the map-data licences in section 7.
The App is free to download. The free tier includes two Area measurements and two Distance measurements, unlimited Markers, every basemap and every unit. A measurement is counted once a shape reaches a result — three points for an area, two for a distance; editing that shape further is not counted again.
Map Area Pro removes the limit, making Area and Distance measurements unlimited. It is offered as an auto-renewable subscription (monthly or yearly) or as a one-time Lifetime purchase.
We may change what the free tier includes, and the price or structure of Pro, in future versions of the App. A change of this kind does not affect a subscription period you have already paid for or a Lifetime purchase you have already made.
Payment is charged to your Apple Account at confirmation of purchase. Prices are shown in the App before you buy and are set by the App Store for your country.
A subscription renews automatically for the same period and price unless you cancel it at least 24 hours before the end of the current period. Your Apple Account is charged for renewal within 24 hours before the current period ends.
You can manage or cancel a subscription at any time in iOS Settings → your name → Subscriptions, or from … → Manage Subscription inside the App. Cancelling stops future renewals; Pro remains active until the end of the period already paid for. No partial refund is given for the unused part of a period.
The Lifetime plan is a non-consumable, one-time purchase. It does not renew and does not expire, for as long as the App remains available on the App Store. It does not entitle you to any separate app we may publish in future.
Purchases can be restored on any device signed in to the same Apple Account using Restore Purchases on the Pro sheet (… → Upgrade to Pro).
Refunds are handled exclusively by Apple under App Store policies; we cannot issue refunds directly.
The App calculates area, perimeter and distance from the points you place on the map, using geodesic formulas on the WGS‑84 ellipsoid. The result is only as good as the placement of those points and the map beneath them. Satellite and aerial imagery may be out of date, offset from true ground position, distorted by terrain or captured at a resolution that hides real boundaries; street and terrain maps are community-maintained and may be incomplete or wrong.
Measurements from the App are estimates for information and planning only. They are not a survey, a legal description or a certified measurement, and must not be used as the basis for land registration, property boundaries, conveyancing, construction set-out, tax or regulatory filings, or any other purpose where an error could cause loss. For such purposes, engage a licensed surveyor.
The App is not a navigation tool. Do not rely on it for driving, hiking, aviation, marine, emergency or safety-of-life purposes.
Map imagery is streamed over the internet from third-party services (section 7). A connection is required to display it; measuring, saving, importing and exporting work offline. We do not control those services and cannot guarantee that any basemap remains available, current or free of interruption.
Saved measurements are stored on your device only. We do not hold a copy and cannot recover measurements lost by deleting the App, resetting a device or a device failure. Export what you want to keep.
We may add, change or remove basemaps, units, file formats and other features in future versions of the App.
You agree not to: use the App to download, cache, scrape or redistribute map tiles in bulk or for any purpose other than viewing them in the App; use the App in a way that places excessive load on the map services it relies on; reverse engineer, decompile or modify the App except as permitted by law; alter the App’s stored data or purchase records, or circumvent the free-tier limit or the purchase mechanism; or use the App in violation of any applicable law.
Satellite imagery is provided by Esri World Imagery and is subject to the Esri Master Agreement and the terms of the underlying imagery providers.
Street Map data is © OpenStreetMap contributors, available under the Open Database License (ODbL). Tiles are served subject to the OSMF Tile Usage Policy.
Terrain tiles are © OpenTopoMap (CC‑BY‑SA), based on OpenStreetMap data and SRTM elevation data.
The map view is built on Apple’s MapKit; purchases are processed by Apple’s App Store.
If you publish or distribute files exported from the App together with map imagery, or screenshots of the map, you are responsible for complying with the attribution and licence terms of the relevant provider. We are not responsible for the availability, accuracy or conduct of third-party services, which are governed by their own terms.
The App, including its design, code, icons and name, is owned by us or used with permission, and is protected by copyright and other laws. Map data and imagery belong to their respective providers as described in section 7. Your purchase grants the personal license in section 1 — it does not transfer ownership of the App or any map content.
The App is provided “as is” and “as available”, without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, accuracy or non-infringement. Without limiting the foregoing, we do not warrant that any measurement is accurate or suitable for any particular purpose, that map imagery is current or correctly positioned, that the App will be uninterrupted or error-free, or that saved data will never be lost.
To the maximum extent permitted by law, we shall not be liable for any indirect, incidental, special, consequential or exemplary damages, or any loss of data, profits, goodwill, land, property or business, arising from your use of or inability to use the App, or from reliance on any measurement it produces. Our total liability for any claim relating to the App shall not exceed the amount you paid for the App and its in-app purchases in the twelve (12) months preceding the claim.
Nothing in these Terms limits liability that cannot be limited under the mandatory law of your country of residence.
These Terms are effective until terminated. Your rights under these Terms end automatically if you fail to comply with them. Upon termination you must stop using the App and delete it.
These Terms are between you and us, not Apple. Apple has no obligation to provide support or maintenance for the App. Apple is not responsible for addressing any claims relating to the App. Apple is a third-party beneficiary of these Terms and has the right to enforce them against you.
We may update these Terms from time to time. The current version, with its effective date, will always be available at this page. Continued use of the App after changes take effect constitutes acceptance.
These Terms are governed by the laws of the country of the developer’s residence, without regard to conflict-of-law rules, except where the mandatory consumer-protection law of your country of residence applies.
