This Privacy Policy describes how we process your data, including personal information when you use the Altroo browser plugin (the “Application”) or visit (the “Website”) – which are collectively referred to as the “Service”. Any references to „us” in this Privacy Policy refer to Plum Research S.A. (a company with its registered office at Al. Piastów 22, 71-064, Szczecin, Poland, National Court Register (KRS) no.: 0000696107; tax identification number (NIP): 8522635486), while the references to “you” refer to persons who use the Service.

We act as the data controller of personal data collected through the Service.

This Privacy Policy also includes information on how we use cookies while providing the Service.

  1. What data do we collect?

    When you use the Service (by running the Application, for instance) and its functionalities (such as its support contact form), we collect the following data about you (the scope of data depends on your use of the Service):

    • contact and account data: your email address and login – which you have provided in the Service or, in case you decide to log in through a third party service provider like Google or Facebook (single sign-on), which you have allowed us to receive from such third parties;

  2. How do we collect your data?

    The data we collect primarily comes from you. We process your data when you use the Service, fill in the support contact form or when you communicate with us in any way.

  3. How do we use your data and on what legal basis?

    We use your data for the following purposes:

    • to pursue our legitimate interests – in particular, to conduct our business, analyze and improve our Service and the services we provide, in order to contact you (by answering your questions asked via the contact form, for instance), to allow you to use the Service, including its account system, as well as to establish, exercise or defend any legal claims;
    • on the basis of your prior, express consent – in particular in relation to the automated processing of your browsing history, to log you in the Service using a third party service provider, to send you newsletters, or to allow you to participate in our surveys or contests.

    We retain your personal data for the term necessary to fulfil the purpose for which it was collected, to fulfil our contractual or legal obligations, or to enforce our rights. Because of this, the storage period depends on the nature of the information and the purposes of processing. We will store the data processed on the basis of your consent until you withdraw it, unless we have another legal basis for such processing.

    In case your personal data is processed based on your consent, you have the right to withdraw that consent at any time, although the withdrawal will not affect the processing that has already taken place.
