CARTEMA
Start free

These terms apply to everyone who uses Cartema: the website at cartema.app, the web application at cartema.mdvia.am with its map viewer and Studio, and the Cartema app for iPhone. By creating an account or signing in you accept them. If a workspace has published a public app, these terms also apply to anyone who views it.

You can use Cartema on a personal plan that you choose and pay for yourself (see pricing), or as a member of an organisation (a client) that uses Cartema under a written agreement with us or with a partner that provides Cartema to it. In an organisation's workspace, the organisation invited you and decides what you can see and do. Where an organisation's agreement with us says something different from these terms, the agreement prevails.

Who we are

Cartema is operated by “M.D.V.I.A.” LLC (“MDVIA”, “we”), a company registered in the Republic of Armenia at 47/1 Khanjyan Street, building 2, Kentron, Yerevan 0001, registration number 273.110.1353425, tax ID 02901114. Contact: info@mdvia.am.

Your account

  • Personal accounts are created by you when you sign up. Accounts in an organisation's workspace are created by invitation from its owner or administrator, or by us on their behalf.
  • An account is for one person. Do not share your password or let anybody else use your session.
  • Choose a password you do not use elsewhere, and tell us at once (and your workspace's owner, if it is not you) if you think someone else has used your account.
  • The owner of a workspace can change your role or remove your access at any time. We may suspend an account or a workspace that breaches these terms or endangers the service or other users, and will inform its owner.

Using Cartema properly

You may use Cartema for your own work or your organisation's, within the role you have. You must not:

  • try to reach workspaces, apps, data or accounts that were not shared with you, or test the security of Cartema without our written permission;
  • copy data out of Cartema in bulk by automated means (scripts, scrapers) unless this was agreed with us in writing; the exports Cartema offers (such as a table as CSV) are there to be used;
  • put an unreasonable load on the service, or interfere with its operation;
  • upload anything unlawful, anything that infringes someone else's rights, or malicious code;
  • use the map data or imagery against the licences under which they were provided to you, including the terms of the basemap and terrain providers listed in the privacy policy;
  • remove attributions shown on the map.

Your data

  • The data you or your organisation put into Cartema (layers, imagery, drawings, attributes, styles and documents) belongs to you or your organisation, or to whoever licensed it to you. We claim no ownership of it.
  • We use it only to provide Cartema to you: to store it, draw it, search it, print it and back it up. We do not sell it, use it to advertise, or use it to train models.
  • You are responsible for having the right to upload what you upload, and for its accuracy.
  • When you close your account, or when an organisation's agreement ends, the data can be handed back in open formats before it is deleted, as described in the privacy policy.

Our software

Cartema (its software, design, name and logo) is licensed to us by its author and protected by copyright. Using Cartema gives you no rights in the software beyond using it as described here. You must not copy, decompile or reverse-engineer it except where the law allows that regardless of these terms.

If you send us suggestions, we may use them without obligation to you.

Maps, measurements and heights

Cartema shows your data as precisely as the data allows, but a map is not a survey. Measurements are computed from the data on screen; heights marked “≈” come from a world terrain model with cells of about 30 m and can be several metres off; basemaps and imagery from third parties may be out of date or misaligned. Check anything that matters (a boundary, a distance, a level) against authoritative sources before relying on it.

The 3D ground of the map is produced using Copernicus WorldDEM-30 © DLR e.V. 2010-2014 and © Airbus Defence and Space GmbH 2014-2018 provided under COPERNICUS by the European Union and ESA; all rights reserved. The organisations in charge of the Copernicus programme by law or by delegation do not incur any liability for any use of the Copernicus WorldDEM-30.

Where the 3D ground is a bare-earth terrain model, it is made from GEDTM30, the Global Ensemble Digital Terrain Model at 30 m by OpenGeoHub (Ho, Hengl et al., 2025; doi:10.5281/zenodo.18887460), licensed under the Creative Commons Attribution 4.0 International licence (https://creativecommons.org/licenses/by/4.0/) and cut into map tiles by Cartema. GEDTM30 is itself derived from Copernicus WorldDEM-30 and ALOS AW3D30 © JAXA, and is provided as it is, without warranty; it is not survey-grade data.

Availability and changes

We run Cartema with care: it is monitored, updated and backed up every day. We may still need to interrupt it for maintenance or to fix a fault, and we will try to do that outside working hours and announce longer interruptions. We improve Cartema continually; features may change or be replaced. For an organisation, what we commit to in terms of availability and support is set out in its agreement.

Keep your own copy of the original files you upload: backups protect the service, not your archive.

Plans, trial and payment

  • Personal plans. The Free, Starter, Plus and Pro plans, what each includes and its price are shown on the pricing page. Paid plans are billed monthly or yearly, in US dollars.
  • Free trial. Each paid personal plan starts with a 14-day free trial, and no card is needed to start it. If you do not subscribe, the trial ends and nothing is charged.
  • Paddle. Personal plans bought online are sold through our online reseller Paddle.com, the Merchant of Record for those orders: Paddle takes the payment and the sales tax, answers payment questions and handles refunds, and its own terms apply to the purchase.
  • Renewal and cancelling. A subscription renews at the end of each period until it is cancelled. You can cancel at any time from your account; cancelling stops the next renewal, and you keep access until the end of the period you paid for. Part of a period is not refunded, except where the law gives you that right. The refund policy has the details.
  • Allowances. A plan's monthly allowances (storage, people, drone photos processed, and use of Buddy and Buddy Pro) apply per calendar month; what is not used does not carry over. Add-ons, such as more storage or another person, are billed with the plan.
  • Organisation plans are agreed with and invoiced by M.D.V.I.A., LLC under a written agreement. They are not sold through Paddle.
  • Plans bought in the Apple App Store or Google Play are sold by those stores under their terms.

Liability

Cartema is provided for professional use. To the extent the law allows, we are not liable for indirect or consequential loss, lost profit or lost data. On a personal plan, our total liability is limited to what you paid for Cartema in the 12 months before the claim; for an organisation, it is limited as set out in its agreement. Nothing in these terms limits liability that cannot be limited by law.

Privacy

How we handle personal data is described in the privacy policy.

Changes to these terms

We may update these terms. The date at the top shows the current version; when a change matters to you, we will tell you (or your organisation) in advance.

Law and disputes

These terms are governed by the law of the Republic of Armenia. Disputes go to the courts of Yerevan, unless an organisation's agreement with us provides otherwise. If you use Cartema as a consumer, this does not take away the protection that the law of the country where you live gives you.
