Privacy
Last update: September 13, 2026
This policy describes what the site actually does with your data. It is written against code, not a template, and there are automatic checks that fail if any of these statements are no longer true.
What we don't do
It's best to start here, because this is what usually surprises the most:
- There is no profiling: no social media tracking pixels, no heat maps, nothing to follow you from one place to another. We do measure site traffic with a third-party service, Vercel Web Analytics, which does not use cookies and cannot follow you outside of here; it's explained in full below under "How we measure traffic," and it's the only thing on this list that's changed since the previous version of this policy. Apart from that, we measure how many times each ad was opened and how many times someone requested contact, and the same for each seller's page: they are counters saved in the ad itself or in the account itself, without IP, without cookie and without session identifier. In addition to the totals, each counter is saved district per week—up to 52 weeks, with older ones deleted—so you can show the poster if their ad is going up or down. For each visit, where you came from is also added, reduced to one of five words: search engine, within the site, direct, social network or other. This classification is done by your browser before sending it, so the address you came from never reaches our servers. The week is the most precise thing saved: there is no day, no time, and no queue per visit, so no counter can be attributed to a person or reconstructed as a browsing history. They are seen by the person who publishes—with the weekly detail if they have a Pro plan—and by the team that moderates the site, added together and by notice, to know if the site works. The only thing that is associated with you are the two weekly quotas – the one for reports techniques and the one for comparisons – and your news, and they are explained below in detail.
- There is no advertising, neither its own nor third parties, so there is nothing to profile.
- We do not sell, rent or give personal data to anyone.
- There are no tracking cookies. The two we use are necessary for the site to function and are explained below.
- Photos are re-encoded before being saved, which discards their metadata: the GPS location that the phone's camera leaves written in the file does not reach our disk or is published.
If you just look at the site
You don't need an account to browse, search properties, look at the map or read the wiki. As long as you just look, the only thing that travels to our server is the language cookie. Your browser also remembers on its own some of your preferences - whether the sidebar is open, where you left the Tero gem, what properties you compared, your last searches and whether you have already seen the map guide -: they are not cookies, they never leave your browser, they are not seen by us or anyone other than you, and they are deleted if you delete the site data. When you open a notice, a mark is also left in the memory of that tab—it is not a cookie and it does not travel anywhere—which serves to avoid counting the same visit twice if you reload the page; it clears itself when you close the tab.
There is one exception, and it is the only thing we keep from what you see: the free plan's quotas. It opens the full report for a number of properties per week, and it allows a number of distinct comparisons per week; in order to count them we save on our server two lists for the current week —what properties you opened, and what properties you placed side by side—. If you are logged in, those lists are associated with your account; if not, they are associated with your IP address, because it is the only thing there to distinguish one visitor from another.
We want to be precise about what that means, because it is browsing data: during that week there is a record on our server of what properties you looked at and which ones you compared with each other. It does not keep the time, it does not keep the order, it does not intersect with anything else and no one looks at it—there is no screen that shows it, not even for the team; it exists to subtract one from the quota and nothing more. It is deleted only after ten days, and if you have an account it is also deleted immediately when you delete the account. In "My Account" you can see how many properties you have opened and how many comparisons you built this week before deciding.
The two cookies
| Cookie | So that | How long does it last |
|---|---|---|
| argenfields_idioma | Remember in which language you prefer to read the site, so as not to detect it again with each visit. | One year |
| argenfields_sesion | Keep your session logged in. It is a token signed with your identifier, email, name and role. It is only read by the server: the JavaScript on the page does not have access. | 30 days |
If you create an account
Login is with Google, Microsoft or with a link that we send you by email, and in all three cases without a password: we never manage or save your password. We receive an identifier, your email and your name, and that is what we save, along with the date you created the account and—if you upload it to publish—your phone number.
If you save a property
The heart saves that property in your list, and for that it is noted on our side what properties you saved, when, and the name you have given it. That name may come from the file you opened, if you loaded property from one. It's in every notice and also in every technical report: you can save a parcel from the cadastre that is not for sale or rent, which is what is useful if you are studying an area instead of buying. We say it with all the letters because it is a piece of information that speaks about you: what someone keeps says where they plan to invest. Only you see it, it is not shared with whoever publishes the notice or with anyone else, and we do not keep how many times you opened it or from where.
It is deleted when you remove it from the list, and it is deleted all together if you delete your account. That's why the button asks you to log in: without an account there is no list, and we don't want to write down what you see without you having requested it.
Your news
If you have an account, we keep a mailbox with what happened on our side: when we approved or rejected a notice from you and why, if a collection failed, if your plan expired or is about to expire, and a weekly summary of how your notices fared in visits. They are our actions towards you, not a record of what you do: the mailbox does not record any page you have visited or any search you have done.
Each new item deletes itself after 90 days, it is done by the database and does not depend on anyone to clean it. Only you see them, they are not shared with anyone, and they are all deleted instantly if you delete your account.
If you publish a property
What you uploaded is saved: title, description, price, area, capacity, declared improvements, location, the perimeter of property and photos. All of that is public, which is the point of posting a notice.
Your contact information—phone, email, WhatsApp—is also public in the sense that anyone who opens the notice can request it. But they are not written in the HTML of the page: they are delivered only when someone expressly requests them, so that a program that runs through the site cannot collect them en masse.
If you contract a plan
The payment is processed by Stripe. The card data travels from your browser to Stripe without going through our server: we don't see it, we don't save it, and we couldn't recover it. On our side is what plan you have, from when, until when, and the brand and the last four digits of the card, which serve to tell you which one you will be charged with.
The plan is renewed only at the end of each period. You can cancel it whenever you want from your account: it stops renewing and you keep access until the date you already paid.
If you set up your seller page
It is optional and you put it together. What you upload is saved: the address of your page, your photo, the description you write, your website, your social network users and the address of your office with its point on the map. All of that is public: the point of that page is to be shareable.
Your phone number and email are NOT written there: they are delivered when someone asks for them, just like in an advertisement. That is why we do not declare them in the data that a search engine reads, even if the format allows it.
If you change the address of your page, the previous one is saved and continues leading to the new one, so that a link you already shared does not stop working. All this is deleted if you delete your account.
How we measure traffic
To know how many people enter the site and what pages they look at, we use Vercel Web Analytics, from the same company where the site is hosted. We say it here in detail because it is the only thing in this document that involves a third party watching your browsing, and because until the previous version of this policy it did not exist.
- It does not use cookies and does not save anything in your browser. There is nothing to accept or reject, and deleting the data from the site does not change what it measures.
- It can't follow you off this site. There is no identifier shared with anyone and no profile that accumulates elsewhere.
- What you receive from each visit is: what page you opened, what address you came from, your country, and what browser, operating system and type of device you are using.
- Your IP address reaches it—as it reaches any server your browser asks for something—and it uses it to count different visitors: it combines it with your browser in a scrambled code that changes every day. It does not save the IP, and since the code is renewed daily, two visits from you on different days cannot be recognized as the same person.
- We see totals: how many visits each page had, where they came from, what country. There is no screen that shows visits one by one, and no way to cross-reference this with your account.
There is one thing we purposely remove before it leaves your browser: everything after the question mark in the address. That is where what you write in the site's search engine travels, so if you search for a property in Pergamino, Vercel receives that you opened the search engine page and not what you searched for. It's the same rule we apply to our own accountants.
Who are they shared with?
With no one, except the services that are needed for the site to work. They are these, and it is good to know which ones your browser sees directly:
| Service | So that | What do you see |
|---|---|---|
| Firebase Authentication (Google) | Verify your identity when entering, and send you the link if you choose to enter by email. | Your email and your name, only when you log in. |
| Google or Microsoft, if you choose to enter with one of them | Be the identity provider of the income. | That you entered this site. |
| MapTiler, OpenFreeMap, EOX and IGN | Serve basemap images. | Your IP address and what area of the map you are looking at. |
| Provincial cadastres and IGN | Draw some parcel and boundary layers. | Your IP address and the area you are looking at. |
| Google translation service | Translate the texts of the site and notices. | Nothing yours: it is consulted from our server, only once by text, never from your browser. |
| Stripe | Collect paid plans. It is the gateway that processes the card. | If you contract a plan: your email, your name and the card information, which go directly from your browser to Stripe. We never see the full number or security code; we only save the brand and the last four digits so we can show you which card you are charged with. If you don't contract anything, your browser doesn't talk to Stripe. |
| Brevo | Sending you the site's emails: the welcome, what happens to your notices, the deletion of your account and the alert that someone asked for your contact details. | Your email address and your name, and the text of the message we send you. We contact it from our server, so it never sees your IP address; your browser never talks to Brevo. We do not send it your phone number or your address, and we do not use it for advertising: these are alerts about things that happened in your account. |
| Vercel | Host the site, and count traffic with Vercel Web Analytics. | Your IP address, the page you opened, where you came from, your country and your browser. Without cookies, and without the part of the address where what you are looking for travels, which we remove before sending it. It is explained above, in “How we measure traffic”. |
| Your browser's voice recognition | Convert what you dictate into text, if you use the microphone to search or to talk to the assistant. | The audio of your voice while the microphone is on. Your browser sends it to its own recognition service, which in Chrome is from Google. We only receive the text, never the audio. It only happens when you press the microphone or the assistant gem. |
| The artificial intelligence service | Interpret a search written in words, draft a notice, and answer what you ask the voice assistant. | The text of what you wrote or said, and the last sentences of that same conversation when you speak to the assistant. It is consulted from our server, so that service does not see your IP address or know who you are. Your email, phone number and address are never sent to them. |
The voice assistant
You can talk to the assistant by tapping the gem floating at the edge of the screen. While the microphone is on you will see it said on the screen, and it turns off only if you stop talking for a while. The assistant can move you around the site and turn on map layers, and nothing else: it can't post, delete, contact anyone, pay, or touch your account.
We don't keep anything from that conversation. The last sentences live in your browser as long as the conversation lasts, they travel with each question so that the assistant understands what you mean, and they leave when you turn off the gem or close the page. The voice with which it answers you is generated by a program that runs on our own server, so the text of the response does not go out to any third party to become audio; if that program is not available, answer with the voice provided by your own browser and nothing comes up there either.
If you are logged in, the assistant can answer you about yours: what plan you have and when it expires, how many ads you published and how many visits and queries they received in the last four weeks. These data are sent to the artificial intelligence service only when your question requires them—if you ask what the water balance is, nothing about you is sent—and only with your first name. Your email, phone number and address are never sent to it, not even if you ask for it: for this it takes you to your account page, which is where they are.
None of those responses are saved in the cache that the site uses to avoid repeating queries. That cache is shared among all visitors and does not distinguish who asked, so saving a plan's expiration date there would show it to the next person who asked the same question. Responses on public data – a zone, a layer, a pricing plan – are saved for up to a week.
Where the data lives
Your data—your account, your notices, your photos—lives in our own database and on our own drive, not on third-party services. There are two exceptions, and both are in the table above: traffic measurement, which by definition is saved by Vercel, and the emails we send you, which go through Brevo and remain in its sending log. The first carries neither your name nor your account; the second does, because an email needs to know who it is going to. There is also a temporary cache that saves responses from public organizations—plot geometries, layers, translations—so as not to request them again, and the usage counters explained below; none of it has your name or your account on it.
We do not create a browsing history or save your IP address with anything you own. We use it in only one place and temporarily: as a key to limit how many AI searches, how many queries to the voice assistant, how many visits and how many contact-detail requests per hour the server accepts, in a temporary annotation that deletes itself when that window is closed and that is not tied to your account or what you looked at. Like any web server, the provider where the site is hosted can keep technical connection logs on its own.
How long
- The published notices, while they remain published.
- Your account data, as long as the account exists.
- The session cookie, 30 days from the last entry; the language one, one year.
- Searched responses from public organizations, until they expire or are cleaned; they don't have your data.
- The two counters for each notice—how many times it was opened and how many times the contact was requested—as long as the notice exists. They are erased with it.
- The emails we send you wait in a queue until they go out, and that queue empties itself after 30 days. What remains after that is Brevo's own sending log, which belongs to them.
Your rights
Law 25,326 on the Protection of Personal Data gives you the right to access the data we have about you, to correct it if it is wrong, to update it and to request that we delete it.
You can access and delete it alone, without asking anyone for permission: in "My account" everything we save is listed and the button to delete it. The deletion takes your username, your publications, your photos, the properties you saved and your news, it is immediate and cannot be undone. It also removes any emails that were still waiting to be sent to you, except one: we let you know by email that the account was deleted, and that is the last email we send you. The only thing that survives are the billing records, if you ever signed up for a plan, and they survive anonymized: see above.
We also try to delete your identity in the login verification service. This is not always possible—it requires a recent login, and our session lasts thirty days—and if it fails, nothing is left hanging: without your username, logging in again creates a new, empty account.
You correct your account type and everything on your seller page from the site. For the rest – your name and email, which are managed by the provider you log in with – you must write to us.
The Agency for Access to Public Information, in its capacity as the control body of Law 25,326, has the power to respond to complaints and claims presented by those whose rights are affected.
Minors
The site is not directed at minors and we do not ask for data knowing that they are. Posting a property requires legal capacity to offer it.
Changes
If this policy changes, we update the date above and notify the site when the change is substantive.
