This page explains, plainly, what entries the code of stradiax.com creates in your own browser's local storage and which analytics we use. The core site does not keep those entries on Stradiax servers: your browser creates them and they live on your device. As our only analytics tool we use Microsoft Clarity, and it is activated only if you explicitly accept it in the consent notice. We do not use Google Analytics, ad pixels or commercial profiling tools.
A "cookie" is a small file your browser stores on your device when a website instructs it to. The technical term also covers other browser-side local storage mechanisms such as localStorage and sessionStorage, which the Spanish Data Protection Agency (AEPD) treats as equivalent. This policy applies to all of them. In every one of the four cases described below, the information lives on your device, not on Stradiax servers, not on third-party servers.
The entries below are created by this site's code in your own browser, on your own device. We do not keep them on our servers: we don't have them stored at all. Of the four, only two (the two chat items) transit to our backend transiently during a conversation, and only for as long as the request takes to process. The other two never leave your browser.
| Name | Type | Purpose | Duration | Category |
|---|---|---|---|---|
stradiax-hero-rot |
localStorage | Rotates the main hero message across 3 variants so each visit sees a different angle on the value proposition. | Persistent until you clear your browser storage. | Functional (exempt from consent per Article 22.2 Spanish LSSI-CE). |
stradiax_chat_session |
sessionStorage | Random session identifier for the chat assistant. Lets the backend apply anti-abuse rate limits without knowing who you are. | Cleared when you close the browser tab. | Functional. |
stradiax_chat_history |
sessionStorage | Stores the recent history of your conversation with the assistant so context is preserved between messages. | Cleared when you close the browser tab. | Functional. |
stradiax-consent |
localStorage | Remembers your choice from the cookie notice so we don't show it on every visit. | 12 months, unless you revoke your choice. | Strictly necessary. |
Two important clarifications:
stradiax-hero-rot and stradiax-consent are read and written directly by the site's JavaScript on your device. They do not travel across the network, they do not reach our servers, and we have no way to know what values they hold.stradiax_chat_session and stradiax_chat_history are attached to each chat message so the backend can apply the anti-abuse rate limit and keep the conversation context. We do not persist them: they are read to generate the reply and discarded as soon as the request finishes. They continue to live in your browser until you close the tab, and only then are they fully removed.If you accept in the consent notice, we load Microsoft Clarity, a product analytics tool we use to understand how visitors navigate the site and improve it. Clarity anonymously captures mouse movement, clicks, scroll, heatmaps and session recordings. It does not capture passwords or data entered in sensitive form fields, and recordings are limited to interaction with the site.
The controller of this data is Microsoft Corporation (Redmond, WA, USA), acting as joint controller or processor depending on context. Microsoft uses this data per its own privacy statement and the Clarity cookie list. Transfers to the US are covered by the EU Data Privacy Framework (DPF) and, as a fallback, by Standard Contractual Clauses.
The cookies and storage entries Clarity creates in your browser (domains clarity.ms, c.bing.com) typically last up to 12 months. If you choose Essentials only, the Clarity script is not loaded and none of those cookies is created.
Beyond Clarity, we do not install Google Analytics, Meta Pixel, LinkedIn Insight Tag or any other tracker. Web fonts and icons are served from public providers (Google Fonts and the Font Awesome CDN), but we do not use cookies from those services to identify you.
The first time you visit the site, a notice appears with two options:
You can withdraw your consent at any time by clearing stradiax-consent from your browser developer tools, or by wiping site storage from your browser's privacy settings. The notice will reappear on your next visit and you can choose again.
Every browser lets you control local storage and cookies from its privacy settings. Official links:
