Terms of Service

The service provider and owner of Check2Fly is Grzegorz Kniażuk, a sole trader operating under the business name Grzegorz Kniażuk Software Development, ul. Garbarska 18A/98, 20-340 Lublin, Poland, Polish tax identification number (NIP) 9462761962, REGON 543548683, entered in the Polish Central Register and Information on Economic Activity (CEIDG).

Check2Fly is an informational service presenting simplified summaries of drone flight rules in selected European countries.

The service is supportive in nature and does not constitute an official source of law, administrative decisions, or binding aviation information.

The purpose of the service is to help the user perform an initial review of key information before flying a drone.

The service is intended primarily for consumers and people who use drones recreationally. Access to the service is not, however, restricted exclusively to those groups.

The service may also be used by operators conducting commercial or professional flights. A flight’s commercial purpose does not by itself determine its operational category; the user must establish the applicable category, qualifications, authorisations, and procedures from current information published by the competent authority. The service content may be incorrect, incomplete, or outdated and does not constitute a professional assessment or confirmation that a specific operation is permitted.

The service may be used by users worldwide, although the content currently published concerns selected European countries.

Access to publicly available content is not subject to a minimum age. The service is not specifically directed at children. Minors should use it with the support of a parent or guardian, and access to the service does not mean that they may independently operate a drone; the applicable age, competence, and supervision requirements must always be checked before a flight.

The service may present, among other things:

• a rule summary for a given country,
• pre-flight guidance and checklists,
• links to authorities, zone maps, and other external sources,
• editorial content related to safe and informed drone use.

The user may use the service only in accordance with the law, good practices, and the intended purpose of the service.

The following is prohibited in particular:

• using the service content in a way that violates the law,
• taking actions that may disrupt the operation of the service,
• automated large-scale data extraction that burdens the service infrastructure,
• bulk, automated, or anticipatory downloading of map tiles, downloading them for offline use, or otherwise using OpenStreetMap Foundation services contrary to its usage policies,
• impersonating the service owner or suggesting that the information is official when it is not.

The content available on Check2Fly is informational and indicative only.

Country data and articles are collected, generated, and refreshed by an automated process that uses artificial intelligence (AI). They are not subject to a fixed review schedule or regular manual or expert substantive verification, and their publication or automated refresh does not mean that they have been approved by a person, expert, or competent authority.

Before any flight, the user must independently verify current laws, airspace restrictions, registration and training requirements, and local operating rules in official sources.

The user is responsible for deciding whether to carry out a flight and for ensuring that their actions comply with applicable law, without prejudice to any liability of the service provider arising under mandatory provisions of law.

Drone regulations, airspace restrictions, and official guidance may change, and an automated process may fail to detect a change, misinterpret a source, or reflect it only after a delay. The service therefore does not guarantee that every summary will be complete and current at all times.

To the extent permitted by applicable law, the service provider is not liable for the consequences of decisions made without the required verification in official sources or for the content, availability, or operation of independent external services beyond its control. This applies in particular to denied flights, administrative penalties, or losses caused by the user’s violation of laws or official restrictions.

The limitation above does not apply to damage arising from circumstances for which the service provider is liable under applicable law.

Nothing in these terms excludes or limits the service provider’s liability for damage caused intentionally or through gross negligence, personal injury, non-performance or improper performance of an obligation to the extent that such a limitation is prohibited, or any other liability that cannot be excluded under mandatory provisions of law. These terms do not limit the statutory rights of consumers.

The content, page layout, descriptions, editorial materials, graphic elements, and other materials available in the service are protected by copyright or other applicable regulations.

The service provider permits copying, quoting, and further distribution of Check2Fly’s own textual materials, in whole or in part, provided that the source is clearly identified as Check2Fly. For online publication, the attribution should include an active link to the service page from which the text was taken, where technically possible.

If the user changes or abridges the text beyond an ordinary quotation, the modification must be clearly indicated, and the altered version must not be presented as an official Check2Fly statement or a current account of the rules.

This permission does not cover third-party materials, including maps, third-party graphics, photographs, or other elements marked with separate authorship or licensing terms. It also does not permit use of the Check2Fly name or logo in a way that suggests cooperation, endorsement, or official status. Statutory rights, including quotation and fair use or fair dealing, remain unaffected.

The OpenStreetMap base layer and geographic data are made available by the OpenStreetMap Foundation and OpenStreetMap contributors under the applicable licence terms. The required “© OpenStreetMap contributors” attribution is displayed directly on the map.

The local country outlines used on the map and in graphics are generated from world-atlas 2.0.2 data, based on Natural Earth 4.1.0. Natural Earth data is in the public domain, while the world-atlas package is licensed under the ISC licence.

The service may contain links to authority websites, zone maps, analytics tools, and other external services.

The service owner is not responsible for the content, availability, operating rules, or privacy policies of those external services.

Using an external link means moving to an independent service that may be subject to its own terms and policies.

Displaying the interactive map automatically downloads the tiles needed for the current view from tile.openstreetmap.org, a service operated by the OpenStreetMap Foundation. Use of the base layer is also subject to the OSMF terms and tile usage policy. The technical data transmitted and how it is processed are described in the Check2Fly privacy policy.

The service may be temporarily unavailable for technical, development, security, or other reasons beyond the service owner’s control.

Service functions may be changed, developed, limited, or removed only in accordance with the rules and for the reasons specified in section 12 of these terms.

For matters concerning the service, contact kontakt@kniazuk.dev.

Reports concerning incorrect or outdated information may be sent by email to kontakt@kniazuk.dev. The information identified in the report is checked by an automated process against available sources. If that process identifies it as incorrect or outdated, it will be corrected or removed. This content error reporting process is separate from the complaint procedure described in section 11.

The OpenStreetMap base layer is an external service provided without a guarantee of continuous availability. Temporary unavailability, restrictions imposed by OSMF, or the connection being blocked by the browser or network may result in only the local country-outline layer being displayed; the country list and the service’s core content remain available.

Using the service requires an end device with Internet access and a current version of a commonly used web browser supporting HTML5, CSS3, encrypted TLS connections, and JavaScript.

Disabling JavaScript may prevent use of the interactive map, search, checklists, language and theme switching, and privacy settings. Basic content may remain partly available, but the service provider does not guarantee that all functions will operate correctly when JavaScript is disabled.

• cookie and localStorage support is needed only to remember the selected language, theme, and privacy decision; blocking them does not restrict access to basic content, but selected settings may not be retained between visits,
• an active email address and an email application or service are required only to send a report, complaint, or other message by email; a complaint may also be sent by traditional post in accordance with section 11,
• external authority websites, maps, and other providers opened through links in the service may set their own independent technical requirements.
• displaying the complete map base layer requires the browser to be allowed to download images over an encrypted connection from tile.openstreetmap.org; blocking this connection does not prevent use of the country list or core content,

An agreement for the provision of electronic services is entered into when the user starts using the service, in particular by opening any of its pages or using an available function, after having been given an opportunity to review these terms. Use of the service is voluntary and free of charge and requires neither an account nor a subscription.

The agreement remains in effect while the service is being used. The user may terminate it at any time, without giving a reason and without incurring costs, by closing the website or ceasing to use the service.

The service provider may temporarily restrict or terminate the provision of the service to a user who violates these terms or the law, disrupts the operation of the service, attempts to compromise its security, or uses it in a manner that threatens the service provider or other persons. Where the nature of the violation permits, the service provider will first request that the user cease the violation.

The service provider may also restrict, suspend, or discontinue the service for technical, security, or legal reasons, or discontinue operation of the service for a justified reason specified in section 12 of these terms. Where possible, information about a planned permanent discontinuation of the service will be published on the website in advance.

Complaints concerning the operation of the service or the provision of electronic services may be submitted free of charge by email to kontakt@kniazuk.dev or in writing by traditional post to: Grzegorz Kniażuk Software Development, ul. Garbarska 18A/98, 20-340 Lublin, Poland. No form is required. Complaints are reviewed by the service provider, who is the administrator of the service.

A complaint should include an email address or postal address for the response, a description of the problem, and the approximate date and circumstances in which it occurred. The sender’s email address is treated as the return address unless another address is specified. No other data is required when submitting a complaint.

Receipt of a complaint sent by email will be acknowledged promptly by reply email. If information necessary to review it is missing, the service provider will request only the strictly necessary information within a reasonable period of at least 7 days. Failure to provide the information does not suspend the response deadline; the complaint will be reviewed to the extent possible on the basis of the information available.

The service provider will respond no later than 14 days after receiving the complaint. In the case of a consumer complaint, failure to respond within that period means that the complaint is accepted, unless specific provisions of law state otherwise.

The response will be sent on a durable medium: by email to the specified email address or by post to the specified postal address. If both addresses are provided and no preferred response method is indicated, the service provider will reply through the same channel by which the complaint was received. The response will include the decision, a brief explanation, and information about any further action. The complaints procedure does not limit any rights available to the user under applicable law.

The service provider may change these terms or the functions of the service only for a justified reason: a change in law or a judgment or decision of a competent authority; a change to official data sources or external services used by the service; the need to ensure security, accessibility, interoperability, or technical compatibility; the correction of errors or ambiguities; the addition or development of functions; the withdrawal of a function or discontinuation of the service because of the permanent unavailability of essential technology, negligible use, or disproportionate maintenance costs; or a change to the service provider’s identification, contact, or organizational details.

Each change must be proportionate to its reason and must not go beyond what is necessary to achieve the stated purpose. A change to these terms or the functions of the service may not in itself impose charges on the user; introducing a paid function requires the user’s separate, express agreement and the provision of the relevant terms before the agreement is entered into.

The current version of these terms and any planned version are published on this page with their publication and effective dates. Material changes are announced at least 14 days before they take effect, together with a brief description. Purely editorial changes, the correction of an obvious error, or changes urgently required by law or security may take effect earlier; the reason and effective date will be stated in the service.

Changes do not apply retroactively and do not affect agreements that ended before their effective date. Because an agreement remains in effect only for the duration of the current use of the service, the new version of these terms applies to agreements entered into from its effective date. A user who is using the service when a change takes effect retains the previous terms until that current use ends, unless an immediate change is required by mandatory law or is necessary to remove a security threat and is legally permitted. The user may cease using the service at any time without cost.

Under the current model, the service does not provide accounts, subscriptions, or continuing obligations and does not use contact addresses for the ongoing provision of the service, so publication in the service is the primary means of notification. If the future nature of the service enables or requires individual notification, information about a material change will be provided sufficiently in advance on a durable medium, such as by email.

If Articles 43p and 43q of the Polish Consumer Rights Act apply to a particular agreement, and a modification of digital content or a digital service materially and adversely affects the consumer’s access to or use of it, the service provider will inform the consumer sufficiently in advance, on a durable medium, of the features and timing of the modification and the consumer’s applicable rights. The consumer may terminate the agreement without notice within 30 days from the date of the modification or from receipt of information about it, if that occurs later. This right does not apply if the service provider has enabled the consumer, at no additional cost, to retain the digital content or digital service in an unchanged state and in conformity with the agreement. These provisions do not limit any more extensive rights under applicable law.

These terms and any agreements for the provision of electronic services concluded under them are governed by Polish law.

The choice of Polish law does not deprive a consumer of the protection granted by provisions that cannot be derogated from by agreement and that apply in the country of the consumer’s habitual residence where those provisions would otherwise be applicable under the relevant conflict-of-laws rules, in particular Article 6(2) of Regulation (EC) No 593/2008 (Rome I). Where such provisions offer the consumer more favourable protection than Polish law, the more favourable protection applies.

Nothing in these terms limits the user’s right to submit a complaint, use statutory out-of-court dispute resolution procedures available to them, or pursue claims before a court having jurisdiction under applicable law. These terms do not establish the exclusive jurisdiction of Polish courts over consumers.

The Polish version of these terms is the source version. The other language versions were prepared using machine translation and are provided for users’ convenience. In the event of discrepancies, the Polish version serves as the point of reference. This does not limit any rights available to consumers under mandatory law or the rule that ambiguous standard terms are interpreted in the consumer’s favour where applicable.

As at the publication date of this version, the service is entirely free of charge and does not offer accounts, payments, subscriptions or a newsletter, display advertising, or use affiliate links. Introducing any of these features requires a prior legal review, appropriate updates to these terms and the privacy policy and, where required by law, the user’s separate consent.
