Pelyr Data Licence 2.0

Version 2.0 · 23 October 2026 · replaces the earlier versions for data made available from that date on

You are free to

• Use it commercially — under the plan that delivers it. Data You receive through Pelyr Stream, the HTTPS API or the MCP server while You hold a paid developer plan (Fleet, Horizon, Global, Enterprise), and data You receive through the map of the Pelyr portal while You hold the Premium Plus map plan, may go into products You charge for. Everything else is for non-commercial use only, unless a written permission from us allows commercial use — also data from the Free developer plan when You hold Premium Plus, and map data on Map Free or Premium when You hold a paid developer plan. Zone alerts follow the zone: alerts of a zone created through the HTTPS API are commercial while You hold a paid developer plan, alerts of a zone created in the portal while You hold Premium Plus. Accounts that existed before 23 October 2026 keep commercial use until 23 December 2026.
• Analyse it. Forecasts, statistics, reports, alerts, models — and, where You have commercial use, sell those.
• Show it. On your map, in your interface, in the documents you export.
• Keep it. What you have received stays yours to use, indefinitely.

Under these conditions

• Credit us — for non-commercial use. “AIS data from Pelyr (pelyr.com), Pelyr Data Licence 2.0”, visible wherever your users see the data. Where you may use the data commercially, crediting us is optional; the credit that other sources require is always due.
• Your product only. The data works inside what you offer. It is not itself what you offer.

You may not

• Pass on the raw data — not as a file, not as a feed, not through an API. Not for money, and not for free.
• Relay the Service.
• Turn your product into a data tap. No bulk or systematic extraction, not even through your own interface, and no export or download that hands your users the positions as data.
• Mine our public map. No systematic extraction from pelyr.com, and no un-masking of the pseudonymous ids it shows.
• Track people. Not for surveillance, harassment or the tracking of individuals.

Legal code

Licensor: Dr. Zürner GmbH, operating under the brand “Pelyr”, Gerichtsstraße 13, 9300 St. Veit an der Glan, Austria, FN 507663 p, Landesgericht Klagenfurt · hello@pelyr.com

0. What this licence covers

This licence governs AIS data, and data products derived from it, made available by the Licensor (“Pelyr”, “we”, “us”), specifically:

1. every data frame, response, message or notification delivered through any interface of the Service, and every group of fields within it, whose license field resolves to the entry that names this licence — against the sources[] array in the welcome frame of your connection, or against the array served by GET /v1/sources;
2. any other AIS data that we make available by any means — including through the public map on pelyr.com and our other public interfaces — whatever the origin of the underlying messages: our own and community receiving stations, or third-party feeds whose providers permit us to license their data on these terms; and
3. data products we derive from such data and make available by any means, including vessel and route events, zone alert events, time slices, track histories, archive extracts and answers of the Pelyr MCP server,

unless it is expressly made available under a different licence.

Data that resolves to a different entry in sources[] is not covered by this licence and remains governed by the licence that entry names.

The Service means every interface through which we make data available to You, including Pelyr Stream, the Pelyr HTTPS API, the Pelyr MCP server, alert notifications to the channels You choose (webhooks, Telegram), and the Pelyr portal. The Pelyr API Terms govern access to it.

The data covered by this licence is referred to as the Licensed Data.

1. Definitions

• You — the natural or legal person exercising the rights granted by this licence. Your has the corresponding meaning.
• Your Product — a product or service that You provide under Your own name and Your own responsibility.
• Derived Result — any output produced from the Licensed Data by analysis, aggregation, modelling, enrichment or presentation, which does not itself contain the Licensed Data or a substantial part of it.
• End User — a person who uses Your Product without themselves obtaining access to the Licensed Data.
• Processor — a person who handles the Licensed Data solely on Your instructions and solely for Your Product, such as a hosting provider or a contracted developer.
• Commercial Use — any use directed towards a commercial advantage or monetary compensation, in particular use in or for a product or service that is offered for a fee or financed by advertising, the sale or licensing of Derived Results, and use in the course of a business, a trade or a profession, including internal business operations. Use by a natural person for purely private purposes, and use for non-profit research or teaching, is not Commercial Use, provided it generates no income.
• Paid Plan — a paid developer plan of the Service (Fleet, Horizon, Global or Enterprise) as described in the Pelyr API Terms, while it is active. The Free Plan is the developer plan without charge. A map plan of the Pelyr portal is not a Paid Plan.
• Community access — the access described in section 9 of the Pelyr API Terms. It is not a Paid Plan, and for section 2.2, data received through the Developer Interfaces under it counts as received under the Free Plan.
• Developer Interfaces — Pelyr Stream, the Pelyr HTTPS API and the Pelyr MCP server.
• Portal Map — the map of the Pelyr portal for signed-in accounts, with its vessel lists and track views.
• Database Right — the sui generis right of the maker of a database under §§ 76c et seq. of the Austrian Copyright Act (Urheberrechtsgesetz) and the corresponding provisions of Directive 96/9/EC and its national implementations.

2. Grant of rights

2.1 Subject to Your compliance with section 3, we grant You a worldwide, non-exclusive, royalty-free and perpetual licence, subject to section 7, to:

1. access, store, reproduce and process the Licensed Data;
2. create Derived Results from it;
3. display the Licensed Data and Derived Results within Your Product; and
4. make Derived Results available to third parties, commercially only as permitted by section 2.2.

The licence itself carries no fee. Fees under a paid plan are payable for access to the Service, not for this licence.

2.2 Commercial use depends on the plan under which You received the data. Each plan grants Commercial Use only for the data it delivers.

1. Licensed Data You received through the Developer Interfaces while Your account held a Paid Plan may be put to Commercial Use.
2. Licensed Data You received through the Portal Map while Your account held the Premium Plus map plan may be put to Commercial Use.
3. Alert notifications follow the alert zone they are about. Those for an alert zone created through the Developer Interfaces may be put to Commercial Use while Your account holds a Paid Plan; those for an alert zone created in the Pelyr portal may be put to Commercial Use while Your account holds the Premium Plus map plan. Where an alert zone was created is fixed when it is created.
4. Licensed Data not covered by (a), (b), (c), (e) or (f) may be used for non-commercial purposes only: in particular data received through the Developer Interfaces under the Free Plan, even while Your account holds Premium Plus; data received through the Portal Map on the Map Free or Premium map plan, even while Your account holds a Paid Plan; alert notifications outside (c); and data received through the public map on pelyr.com.
5. Accounts that existed before 23 October 2026, the date this version took effect, keep Commercial Use during their transition period, which ends on 23 December 2026 (two months after that date): Licensed Data such an account receives through the Service before the end of the transition period, through the Developer Interfaces, the Portal Map or as alert notifications, may be put to Commercial Use whatever its plans.
6. Licensed Data that a written permission from us allows You to put to Commercial Use, within its terms.

Where You may put data to Commercial Use, You may charge for Your Product and for Derived Results made from it. What You may do with a given item of Licensed Data is fixed when You receive it. Taking up a plan later does not permit Commercial Use of data received earlier without it; ending a plan does not withdraw the permission for data received while it was active (section 2.4).

2.3 This licence is not transferable and not sublicensable. Section 4 governs who other than You may handle the Licensed Data. Where You are merged into another company, or split, and Your rights pass by universal succession, the successor enters into these same conditions in Your place; the licence does not thereby extend to any other company in the successor’s group.

2.4 The rights granted in respect of Licensed Data You have already received are perpetual. They survive the end of Your access to the Service and the end of any agreement between You and us. Section 7 is the only exception.

2.5 This licence rests on two independent bases: as a licence under the Database Right, and as a contractual undertaking between You and us. If either basis is unavailable or unenforceable in a given case or jurisdiction, the other continues to apply on its own.

2.6 Rights beyond those granted in this licence are available only by separate written agreement with us.

3. Conditions

3.1 Attribution

Section 3.1 applies to Licensed Data that You may use for non-commercial purposes only under section 2.2. For Licensed Data that You may put to Commercial Use, the attribution is optional.

Wherever the Licensed Data or a Derived Result is visible to End Users — in the interface, on the map, in a document exported from Your Product — You must display:

The notice must be reasonably prominent and reasonably legible in the medium concerned. Placing it only in source code, in a configuration file or in internal documentation does not satisfy this condition.

Where the medium makes a visible notice impracticable — an SMS alert, a voice response, a machine-to-machine interface — a notice in the accompanying documentation or at a stated URL is sufficient for that medium.

Where a Derived Result is an aggregate from which no individual position report can be identified, attribution may be given once for the publication as a whole rather than at each figure.

Where You obtain data through the Pelyr HTTPS API, a single response routinely carries data from more than one source. Attribution is then collective: You must display the notice for every source represented in what You show, this one among them.

3.2 Your product only

The Licensed Data may be used only in and for Your Product.

The test is this: the Licensed Data flows into what You offer. It is not itself what You offer. Where a recipient is receiving, or paying for, the data rather than something You have made from it, this licence does not permit it.

3.3 No redistribution of the data

You must not make the Licensed Data, or a substantial part of it, available to any third party — whether for payment or free of charge — and in particular not:

1. as a file, dump or dataset in any format;
2. through an interface that returns position reports;
3. as part of a database, data product or data collection;
4. by way of sale, licence, sub-licence, publication, or contribution to an open data collection.

3.4 No relay of the Service

So far as it carries Licensed Data, You must not forward, re-serve, proxy or mirror the Service, in whole or in part — neither the frames of Pelyr Stream nor the responses of the Pelyr HTTPS API — and must not allow any third party to receive it through Your access. Individual alert notifications may be shown or passed on within Your Product or to Your own staff, together with any attribution required for them.

3.5 No systematic extraction

You must not carry out, and must not permit, the repeated and systematic extraction of insubstantial parts of the Licensed Data in a manner that amounts, cumulatively, to the extraction of a substantial part.

This applies to extraction through Your Product’s own interface exactly as it applies to any other route. Where Your Product exposes the Licensed Data to End Users, You must take reasonable measures to prevent extraction of that kind through that exposure.

3.6 Model training

You may use the Licensed Data to train, validate or evaluate statistical or machine-learning models.

The resulting model must not be capable of reproducing individual position reports from the Licensed Data on demand, and must not be distributed as a means of making the Licensed Data available. A model that does either is treated as the Licensed Data itself under section 3.3.

3.7 No surveillance of individuals

You must not use the Licensed Data for the surveillance, harassment or tracking of individuals.

3.8 The public map

The map on pelyr.com is a feature of our website. It is not an access route to the Licensed Data, and using it as one is not permitted: You must not extract data from it systematically, whether through the map itself or through the interfaces behind it.

Its anonymous view identifies vessels by a pseudonymous identifier that carries no MMSI and no vessel name, and that is replaced at regular intervals. You must not attempt to resolve that identifier to a vessel, and must not link it across a change, whether by correlating positions or by any other means.

4. Who other than You may handle the data

4.1 End Users may see the Licensed Data and Derived Results within Your Product. They acquire no rights in the Licensed Data. Displaying the data to them is not redistribution under section 3.3.

4.2 Processors may handle the Licensed Data on Your behalf, provided they do so solely for Your Product, solely on Your instructions, and under obligations at least as protective as those in this licence. A Processor acquires no rights in the Licensed Data. You remain fully responsible for their compliance.

The provider of an AI model that processes the Licensed Data on Your behalf during interactive use — for example when You query the Pelyr MCP server through an AI assistant — counts as a Processor, provided it does not use the Licensed Data to train its models.

4.3 No one else. This licence does not extend to companies affiliated with You, whether parent, subsidiary or sister companies. Each requires its own licence.

5. Examples

Illustrations, not an exhaustive list. Where a case is not listed, section 3.2 decides it.

6. No warranty, no liability, and a safety and compliance restriction

6.1 The Licensed Data is provided as is and as available. We give no warranty of any kind. It may be incomplete, delayed, inaccurate, spoofed or entirely absent for any vessel or area at any time.

6.1a Where You are a consumer and received the Licensed Data under a paid plan, Your statutory rights regarding conformity are unaffected.

6.3 For our liability, the following applies:

• We are liable without limitation for damages arising from injury to life, body or health, and for damages caused intentionally or by gross negligence.
• We are not liable for slight negligence, except where an essential contractual obligation is breached (an obligation whose fulfilment makes the proper performance of the contract possible in the first place and on whose fulfilment You regularly rely and may rely); in that case liability is limited to the damage that, at the time the Licensed Data was made available, was objectively foreseeable as typical of a contract of this kind.
• If You are not a consumer, our total liability, except in the cases of the first item, is limited to the fees You paid for the Service in the one month before the event giving rise to the claim.
• Where You are not a consumer and we are liable for slight negligence only, we are not liable for loss of profit, loss of data, business interruption, or any damage arising from the unavailability, incompleteness, delay or inaccuracy of the Licensed Data.
• Where we are liable for slight negligence only, we are not liable for any consequence of use contrary to section 6.2.

Nothing in this licence limits liability under product liability law, including under the Austrian Product Liability Act (Produkthaftungsgesetz).

7. Breach

7.1 If You breach any condition in section 3, the rights granted in section 2 terminate automatically.

7.2 Termination is permanent if the breach concerns section 3.3, 3.5, 3.7 or 3.8, or if You have breached the same condition before. In all other cases the rights are reinstated automatically if You cure the breach within 30 days of discovering it or of our notice of it, whichever is earlier; if You do not, termination is permanent. We may reinstate rights that have terminated permanently at our discretion, and only in writing.

7.3 Once termination is permanent You must cease all use of the Licensed Data and delete such copies of it as are within Your control. Derived Results already created that contain neither the Licensed Data nor a substantial part of it are unaffected.

7.4 Nothing in this section limits any other right or remedy available to us, including termination of Your access under the Pelyr API Terms.

8. Versions

8.1 We may publish new versions of this licence. Each carries its own version number.

8.2 Licensed Data remains subject to the version under which it was made available. Where the sources[] entry resolved for a data frame or an HTTPS response names a licence identifier that carries a version number, that identifier determines the version; otherwise the version published on this page at the time the data was made available applies. A new version applies only to data made available after its publication.

8.3 Data made available under versions 1.0 to 1.2 of this licence remains licensed under those versions, without charge and without time limit, including the commercial use those versions permitted.

9. General

9.1 No trade mark rights. This licence grants no right to use “Pelyr” or any Pelyr name or logo, other than as required or permitted by section 3.1.

9.2 No endorsement. Attribution does not imply that we endorse You or Your Product, and You must not state or imply that we do.

9.3 No other rights. Rights not expressly granted are reserved. This licence does not affect rights You have under mandatory law, including exceptions and limitations to the Database Right.

9.4 Data under other licences. Data that resolves to a different entry in sources[] — for example one licensed under CC-BY-4.0 or NLOD — is governed by that licence and not by this one. Where Your Product combines them, each licence applies to its own part.

9.4a Copernicus data. Imagery and detections derived from Copernicus Sentinel data are not Licensed Data. They remain subject to the Copernicus terms. Wherever they are visible to End Users, You must display “Contains modified Copernicus Sentinel data [year]”, giving the year or years of the data in place of [year].

9.5 Language. The English text is the authoritative version.

9.6 Governing law and jurisdiction. This licence is governed by Austrian law, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods. If You are a consumer — a natural person acting for purposes outside their trade or profession — this choice of law does not deprive You of the protection of the mandatory provisions of the law of Your country of residence. If You are not a consumer, the courts competent for St. Veit an der Glan, Austria, have exclusive jurisdiction.

9.7 Severability. If any provision of this licence is or becomes invalid, the validity of the remaining provisions is unaffected.
