Cookie Policy

Last updated: October 14, 2026

Syncro uses its own necessary cookies and, only with your consent, Google Analytics 4 analytics cookies. This policy explains what we use and how you can choose.

What are cookies?

Small files stored in your browser to remember preferences or measure usage. Only necessary cookies are set by default; analytics require prior consent under Art. 22.2 LSSI-CE and AEPD guidance.

Types we use

Necessary (always on): authentication (next-auth), security, language (NEXT_LOCALE), theme and application cache (PWA service worker) to work offline.
Analytics (only with consent): Google Analytics 4 to measure visits and usage on an aggregate basis.

Cookie table

Manage your consent

You can change your choice at any time from here or the footer.

Google Consent Mode

If you reject analytics, Google Analytics is not loaded and no data is sent (zero send). If you accept, it runs with Consent Mode v2 (analytics_storage granted, ad_* denied).

Browser controls

You can also delete or block cookies in your browser settings. Blocking necessary cookies will break some features.

Updates

We will update this policy if we add new cookies. We will show the banner again when re-consent is needed.
