Cookie Policy
This policy explains which cookies and similar technologies we use on the 24sellio.eu portal, why we use them and what choices you have. The portal is operated by 24SELLIO s. r. o. (the “operator”). We act in accordance with Regulation (EU) 2016/679 (GDPR) and with Section 109(8) of Slovak Act No. 452/2021 Coll. on electronic communications, which transposes Directive 2002/58/EC into Slovak law. This policy supplements the Privacy Policy and the General Terms and Conditions of the portal.
What cookies and similar technologies are
Cookies are small text files stored on your device when you visit a website. They allow the site to remember your settings and to recognise that you are signed in.
The same rules apply to similar technologies that store data on your device — in particular the browser’s localStorage. We therefore list these by name as well, including the period after which the application deletes them itself.
When we need your consent
Two different things must be distinguished. The first is the storing of data on your device, or access to it. This is governed by Section 109(8) of Act No. 452/2021 Coll., under which your demonstrable consent is required. Consent is not required only where the storage is necessary for transmitting a message or strictly necessary for providing a service you have explicitly requested. Browser settings do not count as consent.
The second is the subsequent processing of personal data, which is governed by the GDPR. For signing in and securing your account this is the performance of a contract (Art. 6(1)(b) GDPR); for protection against misuse it is our legitimate interest (Art. 6(1)(f) GDPR); and for functional, analytics or marketing technologies it is your consent (Art. 6(1)(a) GDPR).
We activate analytics and marketing technologies only after your freely given, specific, informed and unambiguous consent (Art. 6(1)(a) GDPR). Without it the relevant scripts are not loaded at all. Refusing is just as easy as giving consent, and you may withdraw your consent at any time without affecting the lawfulness of processing before withdrawal.
Categories
Strictly necessary — without these the portal could not operate securely, or we could not provide a feature you explicitly requested. This covers signing in, protection against CSRF attacks, storing your choice in the privacy settings, the list of listings added to comparison, a draft listing, your answer to the location prompt and your answer to the app installation offer. They are always created only after an active step on your part and are kept only for the periods stated in the tables below.
Functional — these remember your recent searches and the listings you viewed most recently. The portal works without them, so we do not treat them as strictly necessary and store them only after your consent. If you do not give consent, or withdraw it later, we will not create this data on your device and will promptly delete anything already stored.
Analytics — these would measure traffic and how the portal is used so that we can improve it. For this purpose we use Google Analytics 4 (Google Ireland Limited) with IP anonymisation and Microsoft Clarity (Microsoft Ireland Operations Limited). They load only after your consent.
Marketing — these would serve to measure and personalise advertising and content. We currently use none. We do expect to deploy them in the future; if that happens they will form a separate category that you switch on separately, the relevant scripts will not load at all before consent is given, and we will update this policy in advance.
Overview of cookies
Sign-in cookies are created only once you sign in. If you do not have an account, the only items stored on your device are NEXT_LOCALE and, once you make a choice, the privacy-settings entry in browser storage.
Data in browser storage
The values stored in browser storage listed above are not shared with third parties. Some of them may be used to control a portal feature or to prevent the same operation from being carried out repeatedly. Details are given with each individual item.
Items in the Functional category are stored only with your consent. The others are strictly necessary for a feature you explicitly requested and are created only after an active step on your part. Browser storage does not delete anything by itself, so the retention periods stated here are enforced by the application.
What we stopped storing
With this update we removed the storage of data that was not strictly necessary: the visit counter, the flag marking an already counted visit, and the records of already counted views of individual listings. Repeated counting of the same view is now prevented on the server, so nothing is stored on your device for that purpose. If older entries are still present in your browser, the application deletes them itself on your next visit.
Third-party services
Without your consent, no third-party analytics or marketing script runs on the portal’s pages — the relevant scripts are not loaded at all before consent is given, and without it we send no data about your visit even from our server. Below we set out what is loaded and to whom data is sent once consent has been given. This statement does not cover external services that the user knowingly navigates to, for example by clicking a link or continuing to a payment service.
The only technical exception is typography: the portal’s fonts are loaded from Google Fonts (Google Ireland Limited), so when a page is displayed your IP address and basic browser information are transmitted to its servers. According to the provider, Google Fonts does not set cookies when delivering fonts. All other content, including images, is served from our own 24sellio.eu domain.
The footer contains links to our social media profiles. These are ordinary links that store nothing on your device until you click them and leave the portal.
Once you consent to analytics cookies, we load the Google Analytics 4 and Microsoft Clarity scripts, which set their own cookies and process data about site usage, including a truncated IP address.
How to manage your settings
You can open the settings using the button below. There you will find an overview of the categories and the current state of your choice. You may also delete cookies and browser storage data at any time directly in your browser settings. If you delete the strictly necessary cookies, you will have to sign in again.
You may withdraw your consent at any time, just as easily as you gave it — with a single click in these settings. Once withdrawn, we promptly delete the data stored on your device on the basis of that consent. Withdrawal does not affect the lawfulness of processing before withdrawal.
Your rights
Depending on the legal basis and the circumstances of the processing, you have the right of access to your personal data, to rectification, erasure, restriction of processing and data portability, as well as the right to object to the processing. Where processing is based on consent, you have the right to withdraw that consent at any time. Details are set out in the Privacy Policy.
You also have the right to lodge a complaint with the supervisory authority: Úrad na ochranu osobných údajov Slovenskej republiky, Galvaniho Business Centrum II, Galvaniho 7/B, 821 04 Bratislava, dataprotection.gov.sk. Details of processing can be found in our Privacy Policy.
