Cookie Policy

1. What are cookies?

Cookies are small text files stored on your browser or device. They help remember preferences, keep you signed in, protect forms and, if you authorise it, measure site usage.

We also use localStorage for preferences that do not need to be sent to the server on every visit (e.g. light/dark theme).

2. Controller

The controller for cookies on this site is COSTAKEY, Av. País Valenciano, 17, 03140 Guardamar del Segura, Spain. Contact: legal@costakey.life.

3. Types of cookies we use

We classify cookies as follows:

• Strictly necessary (no consent required): PHP session ID (PHPSESSID), CSRF token for secure forms, your cookie banner choice (cookie_consent), language preference.
• Functional: local storage of visual theme (light/dark); improves experience without identifying you for advertising.
• Analytics (optional): activated only if you click “Accept all” on the banner. Helps us understand aggregated traffic and performance. We do not sell data for advertising.
• Third-party payment cookies: when paying via Stripe Checkout, Stripe may set cookies required for fraud prevention and payment completion; see Stripe’s privacy policy.

4. Legal basis

Necessary cookies are based on legitimate interest and technical necessity to provide the requested service. Analytics and non-essential cookies are based on your consent, which you may withdraw at any time.

5. Managing your consent

On your first visit to costakey.life you will see a banner with “Essential only” and “Accept all”. Your choice is stored so you are not asked on every visit.

You may change your mind by deleting site cookies in your browser settings (Chrome, Firefox, Safari, Edge) or using private/incognito mode.

Blocking essential cookies may prevent sign-in or completing bookings.
