After the fulfilment of a given purpose has ended, the data necessary to establish, pursue or defend claims are stored solely for that purpose and to the extent necessary for it. After the retention period expires, personal data are irreversibly deleted or anonymised, if the provisions so permit. Anonymised data, including aggregated data used for statistical and analytical purposes, may be stored without time limit, unless the provisions require a shorter retention period. In the case of claims whose limitation period is two years or more, the retention period may be extended until the end of the calendar year in which the limitation period expires (Article 118, second sentence, of the Civil Code).
3.4.
Where the Controller contacts owners and editors of other websites in order to propose cooperation (for example mutual referrals to the Calculators), the Controller obtains their contact details (first name and surname, e-mail address, name of the website) from publicly available sources, i.e. from the websites of those services. The processing takes place for the purpose indicated in the table above. In the first message, the Controller provides the information referred to in Article 14 of the GDPR or indicates where it can be found, and the data subject may object to further contact at any time.

4. RECIPIENTS OF DATA ON THE WEBSITE

4.1.
For the proper functioning of the Website, it is necessary for the Controller to use the services of external entities, such as a hosting provider, an e-mail provider or a provider of analytics tools. The Controller uses only the services of such processors that provide sufficient guarantees to implement appropriate technical and organisational measures in such a manner that processing meets the requirements of the GDPR and protects the rights of data subjects.

The Controller transfers personal data outside the EEA only when necessary and while ensuring an adequate level of data protection, in particular by: (1) transfer to an entity in a country in respect of which the European Commission has issued a decision finding an adequate level of data protection (for example to an entity in the United States certified under the EU-U.S. Data Privacy Framework); (2) the use of standard data protection clauses adopted by the European Commission; or (3) on the basis of another instrument compliant with Chapter V of the GDPR. With regard to Vercel Inc., the basis for the transfer of data is the certification of that entity under the EU-U.S. Data Privacy Framework and standard contractual clauses.

8. COOKIES ON THE WEBSITE AND ANALYTICS

8.1.
Cookie files (cookies) are small pieces of text information in the form of text files, sent by the server and stored on the side of the person visiting the Website page, for example on the hard drive of a computer or laptop or on the memory card of a smartphone – depending on the device used by the person visiting the Website. Detailed information on cookies, as well as the history of their creation, can be found, among others, here: https://en.wikipedia.org/wiki/HTTP_cookie.
8.2.
The Controller provides on the Website page a tool for easy and active management of cookies – available upon the first visit to the Website page and subsequently available in the footer of the Website page. Active management makes it possible, among other things, to check which cookies are or may be stored while using the Website page, as well as to select and subsequently change the scope and purposes of the use of cookies. When starting to use the Website page, the visitor will be asked to choose cookie settings. Until a choice is made, only necessary cookies are activated. Refusing consent to cookies other than necessary cookies is as easy as accepting them and does not affect the ability to use the Calculators. The visitor’s choice is remembered for a period of 12 months, after which the visitor will be asked to choose again. The choice can be changed or withdrawn at any time.
8.3.
Regardless of the web browser, it is possible to check which cookies are being sent at a given moment by the Website page using tools available, for example, at: https://www.cookiemetrix.com or https://www.cookie-checker.com.
8.4.
Cookies that may be sent by the Website page can be divided into different types according to the following criteria:
1. a)by their provider: first-party cookies, created by the Controller’s Website page, and cookies belonging to third persons or entities other than the Controller;
2. b)by the storage period on the device of the person visiting the Website page: session cookies, stored until the web browser is closed, and persistent cookies, stored for a specified time defined by the parameters of each file or until manually deleted;
3. c)by the purpose of their use: necessary cookies, enabling the proper functioning of the Website page, including remembering the choice concerning cookies; functional cookies, enabling the Website page to be adapted to the preferences of the person visiting the page; analytics cookies, collecting information on how the Website page is used; marketing, advertising and social media cookies, collecting information about the person visiting the page in order to display advertisements and measure their effectiveness.
8.5.
The Controller may process data contained in cookies when visitors use the Website page for the following specific purposes:
1. a)remembering the visitor’s choice concerning cookies and ensuring the proper operation of the page – necessary cookies;
2. b)adapting the content of the Website page to the individual preferences of the visitor, for example the selected units of measurement (metric or imperial) – functional cookies;
3. c)keeping statistics showing how the Website page is used – analytics cookies.
The Controller does not use marketing, advertising or social media cookies on the Website.
The choice concerning cookies and the selected units of measurement are stored in the browser’s local storage (localStorage), not in a cookie. The browser’s local storage is a technology similar to cookies: it allows information to be stored on the visitor’s device and is subject to the same rules as cookies. The selected units of measurement are remembered only after consent to functional cookies has been given; without such consent, the choice applies only to the current page. The provisions of this chapter concerning cookies apply accordingly to the browser’s local storage.
8.6.
As standard, most web browsers available on the market accept the storage of cookies by default. Everyone can determine the conditions for using cookies through the settings of their own web browser. This means that it is possible, for example, to partially restrict or completely disable the storage of cookies – in the latter case, however, this may affect certain functionalities of the Website, for example remembering selected settings.
8.7.
Web browser settings concerning cookies are relevant from the point of view of consent to the use of cookies by the Website. Detailed information on changing cookie settings and on deleting cookies yourself in the most popular web browsers is available in the help section of the web browser and on the following pages – just click the relevant link:
8.8.
The Controller uses on the Website the Google Analytics 4, Google tag (gtag.js) and Google Search Console services provided by Google Ireland Limited (Gordon House, Barrow Street, Dublin 4, Ireland). These services help the Controller keep statistics and analyse traffic on the Website. The data collected are processed within the above services to generate statistics helpful in administering the Website and in analysing traffic on the Website. These data are aggregated. Using the above services, the Controller collects data such as the sources and media through which visitors to the Website are acquired and the way they behave on the Website page, information on the devices and browsers from which they visit the page, the IP address and domain, and geographical data. The analytics tools are activated only after consent to analytics cookies has been given.
8.9.
A person can easily block the sharing with Google Analytics of information about their activity on the Website page – for this purpose, for example, a browser add-on provided by Google Ireland Ltd. can be installed, available here: https://tools.google.com/dlpage/gaoptout?hl=en.

After an Affiliate Link is clicked and the visitor goes to the website of a third party, in particular Amazon, that entity may store on the visitor’s device its own cookies used to determine that the purchase was made via the Website and to calculate the commission. These files are stored and controlled by that entity, not by the Controller, on the terms set out in its privacy policy.
