General Terms of Use & Data License Agreement
Tl;dr: License required in the following cases:
Commercial or for-profit entities: Any use by a for-profit or commercial entity — including government and military contractors — requires a written license from OpenSky Network, regardless of purpose.
Operational REST API use: Use of the REST API in any operational capacity — including integration into a live product, service, or automated system (even if only internal) — requires a previous written agreement, even for non-profit or governmental entities.
To obtain a license, contact contact[at]opensky-network.org.
The following terms comprise the Acceptable Use Policy and Data License Agreement (collectively, the
"AGREEMENT"), for all data sets made available to You by the OpenSky Network, an non-profit
association
pursuant to Article 60 ff. of the Swiss Civil Code, located in Burgdorf, Switzerland. Certain data
sets
may have additional Supplemental provisions. References to this AGREEMENT shall include any and all
relevant Supplemental provisions. OpenSky Network has the authority and reserves the right, in its
sole
discretion, to refuse requests for data set(s) or discontinue further access and use to anyone. If
You
feel Your request is inappropriately denied please contact OpenSky Network by sending a message to
contact[at]opensky-network.org. In consideration for requesting and receiving access to OpenSky Network
data set(s), You acknowledge that You understand and agree to be bound by the terms and conditions
of
this AGREEMENT. Any violation of this AGREEMENT may result in the immediate suspension or
termination of
this AGREEMENT and/or other action entitled by law such as injunctive or equitable relief. You are
individually liable and responsible for compliance with this AGREEMENT. This AGREEMENT is legally
binding under the laws of the Swiss Confederation. You may terminate this AGREEMENT by contacting
OpenSky Network in writing and receiving acknowledgement of such request.
1. LICENSE
OpenSky Network’s authorization to access the data grants You a limited, non-exclusive,
non-transferable, non-assignable, and terminable license to copy, modify, and use the data in

Government entities may obtain an exemption at the discretion of the OpenSky Network.
No license is granted for any other purpose and there are no implied licenses in this AGREEMENT.
Any use by a for-profit or commercial entity requires written permission and a license
granted by the OpenSky Network. This includes any and all government and military contractors.
Operational use of the REST API in any live product, service, or automated system also requires

This AGREEMENT shall become effective as of the date of approval

Network sole discretion. OpenSky Network shall have the right to use any of Your feedback received

(ii) You consent that OpenSky Network can make public or otherwise disclose Your name as the
registered requester, the name of Your Affiliated Institution, the name of the data set(s) that
OpenSky has made available to You under this AGREEMENT, and the brief description of the type of

(iii) You will abide by any and all modifications. If a modification occurs, it will be explicitly
communicated to You via Your registered email address and shall become effective fifteen (15) days

3. USE RESTRICTIONS
If You have any concerns or questions about these restrictions, You are encouraged to contact OpenSky
Network’s management committee via email. To obtain an exemption from any of these restrictions, You
will need a written authorization from OpenSky Network’s management committee.
(i) While using non-anonymized data set(s), You will respect the privacy of persons that may be
identified in the data. For any publication or other disclosure, You will anonymize or de-identify
personally-identifiable information, aircraft identifiers, sensor locations and other data
identified in Supplemental provisions (if any). If You have any concerns or questions about
anonymization, You are encouraged to contact OpenSky Network’s management committee via email.
(ii) While using anonymized data set(s), You will not attempt to reverse engineer, de-anonymize,
derive or otherwise re-identify anonymized information.
(iii) You will not distribute, disclose, transfer or otherwise make available the data set(s) to any
person other than those employed by your institute who are assisting or collaborating with You using
the data set(s). Other entities with whom You are collaborating in research using the data set(s)
must request access to the data set(s) separately and directly from OpenSky Network.
(iv) All conditions, restrictions and obligations attached to this data shall accompany any and all

in any operational capacity — including but not limited to integration into a live product, service,
or automated system — requires a written license from OpenSky Network, regardless of the entity's

independently; (c) the data is or becomes generally available to the public through no wrongful act

privacy is compromised; or (b) You receive any legal, investigatory, or other government demand to
reverse engineer, decrypt, de-anonymize or otherwise disclose anonymized or confidential data.

such as a written description of Your data protection plan or a written affirmation that You have
disposed of any and all copies of the received data set from all systems reasonably known to you.
