Terms of service.

Your account

Keep your account information accurate and your API keys secret. Anything done with your keys counts as done by you, so revoke a key immediately from the dashboard if you think it has leaked. One account per person or organization; you must be legally able to enter into this agreement.

Acceptable use

Use the service lawfully and within the limits of your account. Do not: circumvent or attempt to circumvent rate limits, credit accounting, or usage metering; share, pool, or resell API keys or access to the service; probe or disrupt the service's security or availability; or use automated means to create accounts. We may throttle or reject traffic that threatens the stability of the service for others.

The data

The elevation datasets we serve originate from public open-data programs (for example USGS, NRCan, and INEGI) and remain governed by their source licenses, including any attribution requirements those licenses carry. We do not claim ownership of the source data, and, subject to those source licenses, what you build from data you retrieve through Darly is yours. The service itself (the APIs, normalized catalog and metadata, documentation, and website) belongs to Darly and may not be copied or offered as a competing service.

Accuracy: read this one

Elevation data is derived from third-party surveys and models. It contains errors, gaps, datum differences, and artifacts, and values can change as sources are updated or re-ingested. The service is not suitable for safety-of-life or safety-critical uses, including aviation, navigation, emergency response, or as the sole basis for engineering or construction decisions. Verify independently before relying on any value where the consequences of an error are serious.

Credits, billing, and refunds

Elevation requests, raster extracts, and Darly-hosted downloads are paid for in credits, at the rates on the pricing page. Every account receives free monthly credits, which reset at the start of each calendar month (UTC), do not roll over, and are used before purchased credits. Free-credit amounts may evolve.

Purchased credits are bought in one-time packs; there is no subscription and nothing renews. Payments are processed by Stripe; we never see or store your card details. No VAT is charged (TVA non applicable, art. 293 B du CGI); the price shown is the price you pay. Purchased credits do not expire, are tied to your account, and cannot be transferred or exchanged for cash. When you run out, requests that need credits are rejected until you buy more or your free credits reset; we never bill overages.

Within 14 days of a purchase you can ask us to refund that purchase's unused credits by writing to [email protected]; we refund the unused share of the price to the original payment method. After 14 days, purchases are not refundable. This does not limit any right you have under consumer law, including the right of withdrawal.

If we change prices or what a credit buys, we will give at least 30 days' notice. If a change makes your purchased credits buy less, you can ask for a refund of your unused purchased credits within those 30 days. If we discontinue the service, or close your account for a reason other than your breach of these terms, we refund your unused purchased credits. Credits are forfeited if you delete your account, or if we close it because you broke these terms.

Availability and changes

We work to keep Darly fast and available, but unless you have a written SLA with us the service is provided without an uptime guarantee. We may add, change, or retire features; if we discontinue something you depend on, we will give reasonable notice where practicable.

Termination

You can stop using Darly and delete your account at any time from the dashboard (see the privacy policyfor what happens to your data). We may suspend or terminate accounts that break these terms, abuse the service, or fail to pay, with notice where practicable. What happens to purchased credits on termination is set out under "Credits, billing, and refunds" above. Sections that by their nature should survive, including the data-license, accuracy, and liability sections, do.

Disclaimers and liability

The service and all data are provided "as is" and "as available", without warranties of any kind, express or implied, including fitness for a particular purpose and accuracy. To the maximum extent permitted by law, Darly is not liable for indirect, incidental, special, or consequential damages, or for lost profits, revenue, or data; and our total liability for any claim is limited to the amount you paid us in the twelve months before the claim arose. Nothing in these terms excludes liability that cannot be excluded by law.

Governing law

Darly is operated from France by Nicolas Brown (EI), trading as Darly Geospatial (see the mentions légales). These terms are governed by French law, with disputes belonging to the French courts, except where the consumer-protection rules of your place of residence give you rights that cannot be waived.

Changes and contact

If these terms change materially, we will note it here and email account holders at least 14 days before the changes take effect; continued use after that is acceptance. Questions go to [email protected].
