Effective from 8 October 2026
This policy describes how the data of people who open property proposals prepared by Mateusz Gancarz, Od Deweloperów and shared on this website is processed.
The controller of your personal data is Mateusz Gancarz, Od Deweloperów. The controller prepared the proposal, sent you the link to it and decides what happens to the information about how it is read. In this document we refer to ourselves as “the controller”.
For matters relating to personal data, you can contact the controller at: m.gancarz@oddeweloperow.pl.
This website runs on Listingo (getlistingo.com), operated by Genti sp. z o.o., ul. Niemczańska 39/6, 50-561 Wrocław, Poland, Polish tax ID (NIP) 8992964282. Listingo is a processor: it processes the data of people viewing the proposal only on the controller’s instructions and under a data processing agreement (Article 28 GDPR).
The processing covers storing proposals, hosting the website, collecting and storing reading statistics and property ratings, and sending notifications to the controller. Listingo does not use this data for its own purposes, does not share it with others and uses only the sub-processors listed in section 11. Contact Listingo about data matters at mateusz@marketingagenta.pl.
We process data only for the purposes listed below. Providing contact details is voluntary, but without them we cannot reply to your enquiry. Data is not sold and is not used for automated decision-making.
While you read a proposal, we record:
For each property you can mark “I like it” or “Not for me” and add a comment. We only record them when you click or send them yourself; the controller sees them in their dashboard and may receive an email notification about them. You can withdraw a rating by clicking the same button again.
We do not record your screen or session, and apart from a comment you send yourself, we do not record what you type. Time is only counted while the tab is active and you are interacting with it. The data helps the controller know which properties interested you most and what is worth discussing. We do not build an advertising profile from it and do not combine it with other agents’ proposals.
To tell a repeat visit by the same person from a new visit, a cryptographic hash is created from the IP address and browser name using a secret key. The IP address itself is not stored. Reading measurement does not use cookies and does not store any information on your device.
On your first visit, we show a cookie consent window. You can accept all categories, choose only some or refuse. Optional categories are switched off by default. Necessary cookies are always active, because without them the site cannot remember your choice.
We store your decision in your browser’s storage (key ag-cookies) together with the date it was made. It remains until you clear your browser data. You can change or withdraw your consent at any time here: . Once you withdraw consent, marketing services stop working immediately.
We load fonts from our own server, so your IP address is not sent to font providers.
We show a Google map next to the properties. Until you consent to the “Marketing” category, you see a “Show map” button instead of the map and nothing is loaded from Google. After you consent, Google receives your IP address, may set its own cookies and may process data, including outside the European Economic Area, under its own privacy policy. In this respect, Google is a separate controller.
Proposals may use the Facebook Pixel (Meta), which lets the controller measure the effectiveness of ads and show them to people who have visited the site. The Pixel is not currently enabled on this website; if the controller enables it, this section will apply.
The Pixel only starts after you consent to the “Marketing” category. Meta then receives: identifiers from cookies (_fbp and _fbc), your IP address, browser and device information, and information that you visited the page. We do not send Meta the content of your messages or your contact details.
For the collection and transfer of this data, the controller and Meta Platforms Ireland Limited are joint controllers. The controller is responsible for informing you about the Pixel and obtaining your consent, and Meta for further processing under its own privacy policy, including in the USA. After you withdraw consent, we delete the Pixel cookies and stop sending Meta data about your visits.
When you call, email or send a WhatsApp message, your data (e.g. name, phone number, message content) goes directly to the controller and is used to discuss your purchase. Listingo does not see it. WhatsApp belongs to Meta Platforms, which processes data under its own privacy policy as a separate controller.
Listingo processes data on the controller’s behalf (section 2). The sub-processors Listingo uses to process data are:
Otherwise, data is shared with Google (maps) and Meta (Pixel and WhatsApp) only as described in sections 7–9, and for maps and the Pixel only with your consent.
The hosting provider keeps standard server logs (IP address, time and type of request) to ensure security and diagnose failures. Connections to the website are encrypted (HTTPS).
You have the right to:
To exercise these rights, write to the controller at m.gancarz@oddeweloperow.pl. You can also contact Listingo (mateusz@marketingagenta.pl), which will forward your request to the controller.
