Cookie Policy

Last updated: June 2026

This Cookie Policy explains how ContainerViz uses cookies and similar storage technologies (such as localStorage and IndexedDB) when you use our application.

What are cookies?

Cookies and browser storage are small pieces of data stored on your device. They let a website remember your actions and preferences — for example, keeping you signed in between visits.

Cookies we use

ContainerViz uses only strictly necessary storage. We do not use advertising or third-party tracking cookies.

Name / source	Type	Purpose
Firebase Authentication	Strictly necessary	Keeps you securely signed in to your account.
Firestore offline storage (IndexedDB / localStorage)	Strictly necessary	Caches your load plans so the app works quickly and offline.
cviz2_* (localStorage)	Strictly necessary	Stores your containers locally for instant loading and offline use.
Stripe	Strictly necessary	Secure payment processing and fraud prevention during checkout.
cviz_cookie_consent (localStorage)	Strictly necessary	Remembers that you have seen the cookie notice.

Because we only use strictly necessary storage required to deliver the service you request, these do not require prior opt-in consent under the GDPR/ePrivacy rules. We show a notice for transparency. If we add analytics or marketing cookies in future, we will ask for your consent first.

Managing cookies

You can clear or block cookies and browser storage at any time through your browser settings. Please note that disabling strictly necessary storage will prevent you from signing in and using core features of ContainerViz.

Changes

We may update this Cookie Policy as the Service evolves. The “Last updated” date above reflects the latest version.
