Cookies and analytics
Cookie policy
This website uses analytics cookies and records the course of your visit, and that is why it asks you before installing them. If you don't accept them, none are installed, nothing is recorded and the page works just the same.
In force since 2 September 2026
This English text is a translation provided for convenience. The binding version is the Spanish one, available at política de cookies. In the event of any discrepancy, the Spanish version prevails.
1. Why you see a banner
The obligation to ask for consent arises from installing cookies or other identifiers on your device that are not strictly necessary. This website installs one to measure how the page is used, so it has to ask you beforehand, in accordance with Art. 22.2 of Spanish Law 34/2002.
Until you answer, nothing is installed and the analytics library is not even downloaded. Rejecting costs exactly the same as accepting: two identical buttons, side by side. Closing the page without answering is the same as not accepting.
This policy replaces the previous one, in which the measurement was configured without cookies and for that reason there was no banner. The change is intended to understand the real path taken by whoever visits the page, and it is documented here before being activated.
2. Technical cookies
These are the ones strictly necessary to serve the page and to keep it working and secure, including any that the hosting provider sets to balance load or mitigate abuse. They are exempt from the prior consent requirement under Art. 22.2 of Law 34/2002 and the guidance of the Spanish Data Protection Agency.
In addition, one item is stored in your browser's local storage, not in a cookie:
| Name | Purpose | Duration |
|---|---|---|
ownex_consent |
Remembers whether you accepted or rejected analytics, so you are not asked again on every visit. It is the only item that is also stored when you reject. | 24 months |
3. Analytics cookies
These are only installed if you accept them. Alongside the cookie, browser storage is used for the same purpose, equally subject to your consent. The tools are PostHog, on its European instance, and Google Analytics 4. They serve to know which parts of the page are read, which are ignored and where people leave.
| Name | Provider | Purpose | Duration |
|---|---|---|---|
ph_[key]_posthog |
PostHog (European instance) | Random browser and session identifier. It makes it possible to count visits without duplicating them, to measure how long each one lasts and to know whether you come back. | 12 months |
ph_[key]_window_id |
PostHog (European instance) | Distinguishes one tab from another within the same session. It is not a cookie: it lives in the browser's session storage. | Until the tab is closed |
_ga |
Google Ireland Limited (Google Analytics) | Random browser identifier. It makes it possible to tell visitors apart and count visits without duplicating them. | 12 months |
_ga_[id] |
Google Ireland Limited (Google Analytics) | Stores the state of the current session, to measure how long it lasts and how many pages it includes. | 12 months |
With your permission, the following is recorded: pages viewed and time spent, clicks and elements pressed, scroll depth, sections read, FAQ questions opened, use of the calculator, form submissions and where the visit came from. Those clicks are used to build aggregated heatmaps.
The course of the visit is also recorded, so that scrolling and clicks can be replayed later. What you type into the form fields is masked at source and is never recorded. The full processing, the legal basis and your rights are set out in the privacy policy.
4. How to change or withdraw your decision
Withdrawing consent is as easy as giving it, as required by Art. 7(3) of the General Data Protection Regulation. In the footer of the home page, the Cookie preferences link erases your decision and shows you the banner again.
When you withdraw it, measurement stops immediately and any identifiers PostHog and Google Analytics had stored are deleted from your browser. The withdrawal does not affect the lawfulness of the processing carried out while the consent was in force.
Even if you do nothing, your decision expires after 24 months and you are asked again.
5. What this website does not use
- Advertising or remarketing cookies.
- Cross-site tracking cookies or social media pixels.
- Sale or transfer of browsing data to third parties.
- Automated decisions or profiling with legal effects on you.
6. How to manage them from your browser
Any browser lets you view, block and delete stored cookies from its privacy settings, and to do so site by site. Blocking them does not affect browsing or the form submission: no function of this page depends on the analytics cookies.
7. Changes to this policy
If any new tool using cookies were to be added, this page would be updated before activating it and your consent would be requested again.
