Terms of Service

Last updated: February 20, 2026  ·  Effective: February 20, 2026

These Terms of Service ("Terms") govern your access to and use of the Jiskta Climate Data API and website (collectively, the "Service") operated by Jiskta ("we", "us", or "our"). By creating an account, purchasing credits, or making any API call, you agree to be bound by these Terms. If you do not agree, do not use the Service.

1. The Service

Jiskta provides a programmatic API that queries historical atmospheric reanalysis data (including nitrogen dioxide and particulate matter concentrations) sourced from the Copernicus Atmosphere Monitoring Service (CAMS) operated by ECMWF. The data is delivered in processed form via a proprietary query engine.

2. Data Accuracy and Disclaimer

You acknowledge and agree that:

• Reanalysis data is a modelled estimate of historical atmospheric conditions, not a direct measurement. It inherits the uncertainties, spatial resolution limits (0.1° ≈ 11 km), and temporal resolution limits (hourly) of the underlying CAMS model.
• Our query engine spatially sub-selects and decompresses tile data. While we take care to ensure correctness, query results may contain inaccuracies arising from software defects, tile encoding errors, boundary rounding, or incomplete data coverage.
• We make no warranty, express or implied, regarding the accuracy, completeness, fitness for a particular purpose, or reliability of any data returned by the API.
• Data should not be used for: environmental compliance filings, medical or clinical decisions, aviation or navigation, emergency response, or any application where inaccurate values could cause harm or legal liability.
• We provide no guarantee that data coverage is complete for any given geographic region or time period.

3. Data Source Attribution

The underlying atmospheric reanalysis data is produced by the Copernicus Atmosphere Monitoring Service (CAMS). When publishing or redistributing results derived from the Jiskta API, you must include an attribution notice such as:

"Contains modified Copernicus Atmosphere Monitoring Service information [year]. Neither the European Commission nor ECMWF is responsible for any use that may be made of the Copernicus information or data it contains."

This attribution requirement is imposed by the Copernicus License and passes through to you as a condition of use.

4. Acceptable Use

You may use the Service for any lawful purpose, subject to these restrictions. You must not:

• Redistribute raw API output as a standalone data product or data feed that competes with Jiskta or the Copernicus data programme;
• Use the Service to circumvent, scrape, or systematically archive the entire dataset for purposes other than your own analysis;
• Attempt to reverse-engineer the tile file format or the query engine binary beyond what is permissible under applicable law;
• Share, sell, or transfer your API key to any third party;
• Use automated tooling to hammer the API in ways that degrade service for other users (the adaptive throttling will return HTTP 429, but deliberate abuse may result in account termination);
• Use the Service to process data in violation of any applicable privacy or export-control law.

5. Credits, Payments, and Refunds

• The Service operates on a prepaid credit model. Credits are purchased in fixed packages (Starter, Professional, Enterprise) via Stripe.
• Credits are deducted per query based on the number of geographic regions, time months, and pollutants queried.
• Credits do not expire.
• All purchases are final. We do not offer refunds on purchased credit packages, whether or not the credits have been consumed, except where required by applicable consumer protection law.
• If you believe credits were deducted in error, contact us at [email protected] within 30 days. We will investigate and, if we caused the error, restore the affected credits. We do not offer cash refunds for disputed credit deductions.
• Prices are shown in Euros (EUR) and are exclusive of any taxes that may apply in your jurisdiction.
• We reserve the right to change pricing at any time. Price changes do not affect already-purchased credits.

6. Accounts and API Keys

• You are responsible for keeping your API key confidential. Treat it like a password.
• Any API calls made with your key are your responsibility, regardless of whether you authorised them.
• If you believe your key has been compromised, regenerate it immediately via the dashboard.
• You must provide accurate information when creating your account. One account per person or legal entity.

7. Service Availability

We aim to keep the Service available at all times but provide no uptime guarantee or SLA. The Service may be interrupted for maintenance, security patches, or reasons beyond our control (hardware failure, upstream provider outage, etc.). We are not liable for losses arising from periods of unavailability.

8. Limitation of Liability

To the fullest extent permitted by applicable law:

• The Service is provided "as is" and "as available", without warranties of any kind.
• In no event shall Jiskta, its operators, or contributors be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to loss of profits, loss of data, business interruption, or reputational harm, arising out of your use of or inability to use the Service or the data it provides.
• Our total aggregate liability to you for any claim arising from or related to these Terms or the Service shall not exceed the total amount you paid us in the 12 months preceding the claim.
• This limitation applies even if we have been advised of the possibility of such damages.

Some jurisdictions do not allow limitation of certain warranties or liabilities. In such jurisdictions, our liability is limited to the minimum extent permitted by law.

9. Indemnification

You agree to indemnify and hold harmless Jiskta and its operators from any claim, loss, liability, or expense (including reasonable legal fees) arising out of: (a) your use of the Service in violation of these Terms; (b) your violation of any third-party rights; or (c) any decisions you make based on data returned by the API.

10. Intellectual Property

The Jiskta query engine, tile format, website, and API design are proprietary. Nothing in these Terms grants you any licence to the underlying software or infrastructure. The underlying atmospheric data is subject to the Copernicus licence (see Section 3).

11. Termination

We may suspend or terminate your account at any time for material breach of these Terms, illegal use, abuse of the API, or non-payment of chargebacks. On termination, unused credits are forfeited unless termination was caused by our error, in which case we will refund unused credit value at the applicable package rate.

You may close your account at any time by contacting [email protected]. Unused credits are non-refundable on voluntary account closure.

12. Changes to These Terms

We may update these Terms from time to time. Material changes will be notified by email to the address on your account at least 14 days before they take effect. Continued use of the Service after that date constitutes acceptance of the revised Terms.

13. Governing Law and Disputes

These Terms are governed by the laws of Belgium, without regard to conflict-of-law principles. Any dispute that cannot be resolved informally shall be submitted to the exclusive jurisdiction of the courts of Belgium. If you are a consumer in the EU, you retain any mandatory protections granted by the laws of your country of residence.
