The User retains full ownership to the content uploaded on the Pensoft website and associated ARPHA Platform. We claim no intellectual property rights over the material provided by the User to Pensoft. However, by setting pages to be viewed publicly (Open Access), the User agrees to allow others to view and download the relevant content.

The User may not copy, modify, alter, publish, transmit, distribute, display, participate in the transfer or sale, create derivative works or, in any way, exploit any of the Copyrighted Material, in whole or in part, without written permission from the copyright owner.

Open Access Materials

Pensoft is a supporter of open science. Open access to content is clearly marked, with text and/or the open access logo, on all materials published under this model. Unless otherwise stated, open access content is published in accordance with the Creative Commons Attribution 4.0 license (CC-BY).

Privacy Statement

Users agree to submit their personal data to this Journal.

Pensoft and its hosting platform ARPHA collect personal information from users (i.e. name, postal and email address) only for the purpose of its services.

All personal data will be used exclusively for the purposes stated on the website and will not be made available for any other purpose or to third parties.

In the case of co-authorship, each of the co-authors states that they agree that their personal data are collected, stored and used by Pensoft.

When one of the co-authors of a manuscript is not registered with Pensoft, it is presumed that the corresponding author who is registered has requested and obtained his/her consent that his/her personal data will be collected, stored and used by Pensoft.

The corresponding author ensures the provision of an e-mail address to the unregistered co-author, to whom Pensoft will send a message inviting the unregistered co-author to give his/her explicit consent for the processing of his/her personal data by Pensoft.

Pensoft is not deemed responsible if the provided e-mail is inaccurate or invalid. In such cases, it is assumed that the processing of the personal data of the unregistered co-author is done on a legal basis and with a given consent.

Pensoft undertakes to collect, store and use the provided personal data of third parties (including but not limited to unregistered co-authors) solely for the purposes of the website, as well as in those cases explicitly stated by the legislation.

In case Pensoft starts using personal data for purposes other than those specified in the Terms of Use, it undertakes to immediately inform the person and request his/her consent.

If the person does not give his/her consent to the processing of his/her personal data pursuant to the preceding paragraph, the Journal shall cease the processing of the personal data for the purposes for which there is no consent, unless there is another legal basis for the processing.

Users may request Pensoft to correct their personal data if the data is inaccurate or outdated and Pensoft is obliged to correct the inaccurate or outdated personal data in a timely manner.

Users may request Pensoft to restrict the use of their personal data insofar as this limitation is not contrary to the law or the Terms of Use.

Users may request their personal data to be deleted (the right to be forgotten) by Pensoft, provided that the deletion does not conflict with the law and the Terms of Use.

The User has the right to be informed:

  • whether his or her personal data have been processed;
  • for which purposes the personal data are processed;
  • the ways in which his/her personal data are processed;
  • the types of personal data that the journal processes.

The User undertakes not to interfere with and impede Pensoft activities in the exercise of the provided rights.

In case of non-fulfilment under the previous paragraph, Pensoft reserves the right to delete the User's profile.

Disclaimer of Warranty and Limitation of Liability

Neither Pensoft and its affiliates nor any of their respective employees, agents, third party content providers or licensors warrant that the service will be uninterrupted or error free; nor do they give any warranty as to the results that may be obtained from use of the platform, or as to the accuracy or reliability of any information, service or merchandise provided

Legal, medical, and health-related information located, identified or obtained through the use of the service, is provided for informational purposes only and is not a substitute for qualified advice from a professional.

In no event will Pensoft, or any person or entity involved in creating, producing or distributing the service or the contents included therein, be liable in contract, in tort (including for its own negligence) or under any other legal theory (including strict liability) for any damages, including, but without limitation to, direct, indirect, incidental, special, punitive, consequential or similar damages, including, but without limitation to, lost profits or revenues, loss of use or similar economic loss, arising from the use of or inability to use the Platform. The User hereby acknowledges that the provisions of this section will apply to all use of the content on the Platform. Applicable law may not allow the limitation or exclusion of liability or incidental or consequential damages, so the above limitation or exclusion may not apply to the User. In no event will Pensoft’s total liability to the User for all damages, losses or causes of action, whether in contract, tort (including own negligence) or under any other legal theory (including strict liability), exceed the amount paid by the User, if any, for using the service.

Third Party Content

Pensoft may be solely a distributor (and not a publisher) of SOME of the content supplied by third parties and Users of the Platform. Any opinions, advice, statements, services, offers, or other information or content expressed or made available by third parties, including information providers and Users, are those of the respective author(s) or distributor(s) and not of the Provider.
