Cookie policy
Cookie policy
This policy describes the cookies and similar technologies used on stelvia.space, in accordance with Directive 2002/58/EC («ePrivacy Directive»), Article 22.2 of Spanish Law 34/2002 (LSSI-CE) and the Spanish Data Protection Agency (AEPD) Guide on the use of cookies in its current version.
1. What are cookies
A cookie is a small text file that a website installs on your device when you visit it. It allows the site to recognise the user, remember preferences or measure site usage. The rules also apply to equivalent technologies such as browser local storage and device identifiers.
2. Types of cookies we use
We distinguish three categories: (a) strictly necessary cookies for the site to work, which do not require consent; (b) preference cookies, which remember your choices (language, accessible mode) and are installed only with your consent; (c) analytical cookies, intended to measure aggregate site use. Stelvia uses PostHog Cloud EU (Frankfurt servers) to measure the conversion funnel in aggregate. This category is only activated if you accept analytics cookies via the consent banner, and it is consent-gated (PostHog is not initialised until you give your consent). We also use Sentry for technical error diagnostics: it does not install first-party cookies, it relies on legitimate interests (Art. 6.1.f GDPR) rather than consent, and the full details are in the privacy policy.
3. Cookies and storage table
The cookies and storage items currently in use are listed below:
| Name | Provider | Purpose | Duration | Category |
|---|---|---|---|---|
| __stripe_mid | Stripe Payments Europe Ltd. | Payment fraud prevention. | 1 year | Necessary |
| __stripe_sid | Stripe Payments Europe Ltd. | Payment session identifier. | 30 minutes | Necessary |
| NEXT_LOCALE | Stelvia (next-intl) | Remember the language chosen by the user. | 1 year | Preferences |
| stelvia_consent | Stelvia | Store the user's choice on cookies and show or hide the banner. | 12 months (localStorage) | Necessary |
| ph_*_posthog | PostHog Cloud EU (Frankfurt) | Measure the conversion funnel (tier page views, dedications and purchases) in aggregate. Only loaded if you accept the "Analytics" category. | 12 months | Analytics |
Sentry (technical error diagnostics) is active on the site but does not install first-party cookies on your device, so it falls outside the scope of this table; its purpose and lawful basis are described in the privacy policy. If we enable additional cookie-based features (session replay, A/B testing) in the future, we will update this table with the new identifiers and purposes.
4. How to manage your consent
On your first visit we display a banner that lets you (a) accept all cookies, (b) accept only the technical ones or (c) customise your choice by category. Your decision is stored in your browser for twelve months. You can change it at any time via the «Manage cookie preferences» link in the footer, or by deleting cookies from your browser. Strictly necessary cookies cannot be disabled because the site cannot function without them.
5. Browser configuration
Beyond the banner, most browsers let you control cookies from their privacy settings: Google Chrome, Mozilla Firefox, Safari, Microsoft Edge and Brave. Blocking or deleting cookies may affect parts of the site.
6. Updates
This policy may be updated when we add new cookies, change providers or when the law evolves. We recommend reviewing it periodically; the date at the end of the document indicates the current version.
