Last updated: March 27, 2026
This Cookie Policy explains how Philosophi ("we", "us", or "our"), operated by Philosophi, uses cookies and similar tracking technologies on philosophi.app.
1. What Are Cookies?
Cookies are small text files placed on your device when you visit a website. They are widely used to make websites work correctly, remember your preferences, and provide information to website owners.
Similar technologies include local storage and session storage, which work in a comparable way and are covered by this policy.
2. Types of Cookies We Use
We use the following categories of cookies:
| Category | Purpose | Examples | Can be disabled? |
|---|---|---|---|
| Strictly Necessary | Required for the site to function. These enable you to log in, stay signed in, and use your account securely. | Authentication session cookies set by Clerk; security cookies set by Cloudflare | No — the site cannot function without these |
| Functional | Remember your preferences and personalise your experience, such as your reading progress and saved library. | Local storage entries for reading progress and UI state | Yes, but some features will not work correctly |
| Analytics | Help us understand how visitors use the site so we can improve it. Data is aggregated and not linked to individual users. | Vercel Analytics (privacy-friendly, no fingerprinting) | Yes |
| Advertising | Used to serve relevant advertisements. We currently show non-targeted ads only and do not use advertising cookies at this time. If this changes, we will update this policy and notify you. | None currently | Yes |
3. Third-Party Cookies
Some cookies on Philosophi are set by third-party services we use to operate the site. These third parties have their own privacy and cookie policies:
- Clerk — authentication and account management. Clerk Privacy Policy
- Cloudflare — security, DDoS protection, and CDN. Cloudflare Privacy Policy
- Vercel — hosting and analytics. Vercel Privacy Policy
- Stripe — payment processing (on subscription/checkout pages only). Stripe Privacy Policy
We do not use Google Analytics or any other Google tracking services.
4. How to Control Cookies
You can control and delete cookies through your browser settings. The links below explain how to manage cookies in the most common browsers:
Please note that disabling strictly necessary cookies will prevent you from signing in and using your account.
We currently do not respond to Do Not Track (DNT) browser signals, as there is no industry-standard approach to honouring them. Vercel Analytics does not track individual users regardless of DNT status.
5. Changes to This Policy
We may update this Cookie Policy from time to time, particularly if we introduce advertising cookies or new third-party services. We will notify you by email before any material changes take effect.
