Cookies are small text files that websites store on your device (computer, tablet or mobile) when you visit them. Cookies allow the website to remember your actions and preferences (such as language, font size and other display options) over a period of time, so that you do not have to reconfigure them each time you return to the site or navigate from one page to another.
In addition to cookies in the strict sense, Booka uses similar local storage technologies (localStorage, sessionStorage) for the same purposes. References to “cookies” in this policy also include these technologies. In the Booka mobile application, device identifiers and similar local storage technologies are also used.
The use of cookies on our Platform is governed by:
Strictly necessary cookies are installed without prior consent, as they are essential for the operation of the Platform (Art. 22.2 LSSI-CE, technical exemption). For the other categories (analytical, functional, marketing), we request your informed consent before their installation through our cookie banner. You may change your preferences at any time.
These are essential for the basic operation of the Platform. Without them, the website and the app cannot function correctly. They include session, authentication, payment processing and fraud prevention cookies. They do not require consent.
These allow us to remember your preferences and configuration options to improve your user experience, such as the selected language or A/B test assignments. These cookies do not track your activity on other websites.
These allow us to analyze how users navigate the Platform, which pages they visit most frequently, and how they interact with the different elements. This information helps us improve the operation and usability of the Platform. We use PostHog for event analytics and Microsoft Clarity for session recordings and heatmaps.
These are used to display relevant content and personalized advertising within and outside the platform. They include the Meta (Facebook) pixel, LinkedIn Insight Tag and HubSpot for campaign nurturing and attribution. If in the future we decide to incorporate other marketing cookies, we will update this policy and request your consent before their installation.

Consent for the use of these technologies is requested at the time of installation and first opening of the app, in accordance with the guidelines of the Apple App Store and Google Play Store.
You can manage your cookie preferences at any time through our cookie configuration panel, accessible from the “Configure cookies” link in the footer of our website. From there you can accept or reject each category of cookies (except strictly necessary ones, which cannot be disabled).

Some cookie providers (PostHog, Microsoft Clarity, Google Analytics, Meta, LinkedIn, HubSpot, Stripe) process data outside the European Economic Area. These transfers are carried out with the appropriate safeguards provided for in the GDPR:
For more information on international transfers and providers, see our Privacy Policy.
We may update this Cookie Policy periodically to reflect changes in the cookies we use, regulatory changes or improvements to our Platform. Any change will be published on this page with the revised last updated date. In the event of significant changes affecting new categories of cookies or a substantially different processing of your data, we will request new consent through the cookie banner.
If you have any questions about the use of cookies on our Platform:
We also inform you that you have the right to lodge a complaint with the Spanish Data Protection Agency (AEPD) if you consider that the processing of your data through cookies infringes the applicable regulations: www.aepd.es.
