Comprehensive explanation of how Cerri Lisa utilizes essential session cookies and client-side storage technologies in compliance with European ePrivacy directives and CNIL recommendations.
Cookies are small text files placed on your computer, smartphone, or other computing device when you visit a website. In addition to HTTP cookies, modern web browsers utilize client-side localStorage to maintain user interface preferences (such as calculator inputs and consent state) without transferring data to external servers on every HTTP request.
Cerri Lisa operates under a strict Clean Human Code Footprint standard. We do not deploy third-party advertising tracking networks, behavioral remarketing pixels (e.g., Meta Pixel, Google Ads remarketing), or fingerprinting mechanisms. Our telemetry is strictly minimal, transparent, and focused on site security and utility responsiveness.
We classify the client-side storage mechanisms utilized on https://zenovio.info into two clear categories:
| Category | Purpose | Legal Basis | Necessity |
|---|---|---|---|
| Strictly Necessary | Session security, CSRF defense, and recording your cookie consent preferences. | Legitimate Interests (ePrivacy Art. 5.3 exemption) | Mandatory (Cannot be disabled) |
| Functional & Calculators | Retaining acoustic room dimensions and bitrate parameters during your active browser session. | Legitimate Interests / User Request | Optional |
| Performance & Diagnostics | Anonymized, aggregated load time telemetry to ensure server uptime and response speed. | User Consent (GDPR Art. 6.1.a) | Optional (Opt-in via Banner) |
