Cookie Policy
Effective Date: July 1, 2026
1. What Are Cookies?
Cookies are small text files stored on your device by a website. They are widely used to make websites work, remember preferences, and provide information to site owners.
2. Cookies We Use
### 2.1 Strictly Necessary Cookies
These cookies are essential for the Service to function. They cannot be disabled.
| Cookie / Storage | Purpose | Duration | Set By |
|---|---|---|---|
| sb-*-auth-token | Supabase authentication session — keeps you logged in | Session | Supabase |
| fp_theme (localStorage) | Remembers your dark/light mode preference | Persistent (no expiry) | First Principles Hub |
| cookie-consent (localStorage) | Records your cookie consent preferences | 12 months | First Principles Hub |
### 2.2 Analytics Cookies
We do not currently use any analytics cookies. We do not use Google Analytics, Mixpanel, PostHog, or similar services.
### 2.3 Advertising / Marketing Cookies
We do not use any advertising or marketing cookies. We do not serve ads, retarget visitors, or run social media pixels.
3. Third-Party Cookies
Third-party services integrated into our Service may set their own cookies:
| Service | Cookie Examples | Purpose |
|---|---|---|
| Supabase | sb-access-token, sb-refresh-token | Authentication session management |
These are strictly necessary for the Service to function.
Paddle (our payment processor) may set cookies when you interact with the checkout flow. Their cookie usage is governed by Paddle's own privacy policy.
4. How to Manage Cookies
### 4.1 Cookie Banner When you first visit our site, a cookie banner allows you to accept or decline non-essential cookies. Since we only use essential cookies, no consent is required for our own cookies under the ePrivacy Directive — but we provide the banner for transparency.
### 4.2 Browser Settings You can block or delete cookies through your browser settings:
- Chrome: Settings → Privacy and Security → Cookies and other site data - Firefox: Options → Privacy & Security → Cookies and Site Data - Safari: Preferences → Privacy → Manage Website Data - Edge: Settings → Cookies and site permissions
Note: blocking essential cookies will prevent you from signing in or using the Service.
### 4.3 Do Not Track Our Service does not respond to Do Not Track (DNT) signals because we do not track users across third-party websites.
5. Changes to This Policy
We may update this Cookie Policy from time to time. Changes will be posted on this page with an updated effective date.
