This Cookie Policy explains how Brianni Ltd. uses cookies and similar technologies on our website and services.
Zero-Knowledge Protection
Your vault content is protected by zero-knowledge encryption and is never affected by cookies. We cannot access your encrypted data regardless of cookie usage.
1. What Are Cookies
Cookies are small text files stored on your device when you visit our website. They help our service function properly and provide you with a better experience.
2. Cookies We Use
Essential Cookies
These are necessary for our service to work and cannot be disabled:
Authentication
To keep you logged in securely
Security
To protect against fraud and unauthorized access
Session Management
To maintain your account session
Core Functionality
To enable basic service features
Analytics Cookies (Optional)
These cookies help us understand how you use our site so we can improve it. They are only set after you give explicit consent:
Google Analytics 4
Collects anonymous usage statistics such as pages visited, session duration, and general device information
Retention: Up to 14 months
PostHog (EU region)
Product analytics covering page views and feature usage. Hosted in PostHog's EU region (eu.i.posthog.com). Persistence is in-memory only — PostHog sets no cookies and writes nothing to your browser's local storage, but processing of IP and page URL still requires your analytics consent.
Retention: per PostHog's default (configurable in their app)
Your Control
You can accept or reject analytics at any time via the consent banner. Rejecting them does not affect your use of the service. If you accept and later revoke consent, we instruct both Google Analytics and PostHog to stop capturing further data.
Local Storage
We also use browser localStorage (not cookies) for the following purposes:
cookie-consent: Stores your cookie consent preferences (accepted or rejected analytics cookies) so the consent banner does not reappear on subsequent visits.
Brianni does not use marketing or advertising cookies. We do not sell or share your browsing data with third parties for advertising purposes.
3. Third-Party Cookies
We use cookies from trusted providers:
Stripe
For secure payment processing during checkout. Stripe sets cookies only during active payment flows.
Retention: Session-based (cleared after checkout completes)
Google reCAPTCHA
For bot protection and security verification. reCAPTCHA may set cookies to assess whether interactions are from genuine users.
Retention: Up to 6 months (set by Google)
Google Analytics
For anonymous usage analytics. Only loaded after you consent to analytics cookies via the consent banner.
Retention: Up to 14 months (requires consent)
PostHog
Product analytics. Loaded only after you consent. Sets no cookies (in-memory persistence only); processing of IP / page URL still requires consent under PECR. Hosted in EU region.
Retention: per PostHog defaults (no browser-side storage)
4. Your Cookie Choices
Managing Cookies
When you first visit Brianni, a consent banner lets you choose whether to accept analytics cookies. You can change your preference at any time by clearing your browser's local storage for this site, which will cause the consent banner to reappear.
Accept all: Enables analytics cookies alongside essential cookies
Essential only: Only strictly necessary cookies are used; no analytics data is collected
Your browser settings can also block or delete cookies, though this may prevent sign-in
Essential Cookies
Essential cookies cannot be disabled as they are required for account security and core service functionality. No consent is required for these under PECR Regulation 6(4).
Browser Controls
You can block or delete cookies through your browser settings, though this may affect service functionality.
