Cookie Policy
Last updated: February 2026
1. What Are Cookies
Cookies are small text files stored on your device when you visit a website. They help websites remember your preferences and understand how you interact with content. Sleep Bible uses cookies and similar technologies to provide, protect, and improve our service.
2. Categories of Cookies We Use
Essential Cookies
Required for the website to function. These include authentication session cookies (Firebase Auth), security tokens, and cookie consent preferences. You cannot disable these without affecting core functionality.
Analytics Cookies
We use Google Analytics 4 (GA4) to understand how visitors interact with our marketing pages. These cookies collect anonymous usage data including pages visited, time spent, and traffic sources. Analytics cookies are loaded only after you consent.
Functional Cookies
These remember your preferences such as theme settings, language, and playback preferences. They enhance your experience but are not strictly necessary.
3. Specific Cookies
| Cookie | Purpose | Duration |
|---|---|---|
| sb-cookie-consent (local storage, not a cookie) | Stores your cookie/analytics consent preference | Until cleared |
| Firebase Auth | Authentication session management | Session |
| _ga, _ga_* | Google Analytics 4 - anonymous usage tracking | 2 years |
| __stripe_mid | Paddle/Stripe fraud prevention during checkout | 1 year |
4. Third-Party Cookies
The following third-party services may set cookies when you use Sleep Bible:
- Google Analytics - website usage analytics
- Firebase - authentication and app functionality
- Paddle - payment processing (during checkout only)
- Sentry - error tracking and performance monitoring
In addition, optional Vercel Analytics and Vercel Speed Insights can run on our hosting platform. They are cookieless, but they do process request data: URL path, IP/User-Agent-derived signals, and Web Vitals timings. They run only after you accept optional analytics consent. Sensitive route identifiers (for example Firebase user IDs in share links or session IDs) are tokenized before the event leaves your browser, and query strings are stripped. They do not track you across other sites. When you withdraw consent, we stop new collection in your current session as completely as the SDK allows (Analytics mode is set to development, the Speed Insights queue function is replaced with a no-op, and the injected script tags are removed); a page refresh after withdrawal fully unloads any remaining script code.
5. How to Manage Cookies
You can manage your cookie preferences through the cookie consent banner that appears when you first visit our website. You can also control cookies through your browser settings:
- Chrome: Settings → Privacy and Security → Cookies
- Safari: Preferences → Privacy → Manage Website Data
- Firefox: Settings → Privacy & Security → Cookies
- Edge: Settings → Cookies and Site Permissions
Note: Disabling essential cookies may prevent you from using certain features of Sleep Bible, including logging in and managing your subscription.
