Cookie Policy
This Cookie Policy explains what cookies and local storage Pattern5 uses and why.
1. Introduction
Cookies are small text files stored on your device when you visit a website. Pattern5 uses a minimal set of cookies — all are either strictly necessary for authentication and security or functional preferences. We do not use advertising or tracking cookies.
3. Local Storage
We also use browser localStorage for UI preferences. This data never leaves your browser and is not transmitted to our servers.
| Key | Purpose |
|---|---|
theme | Theme preference (supplements the theme cookie for server-side rendering) |
ai-chat-app-preferred-model | Preferred AI model for content generation |
admin-customers-view-mode | Admin dashboard display preference (admin users only) |
oauth_return_url | Temporarily stores redirect URL during OAuth login (cleared after use) |
4. Third-Party Services
- Stripe: When you visit Stripe's checkout or billing portal (via redirect), Stripe may set cookies on the stripe.com domain. These are governed by Stripe's privacy policy and are not present on pattern5.com.
- Sentry (production): The Sentry SDK may use internal browser storage for error tracking. No tracking cookies are set.
5. Managing Cookies
You can manage cookies through your browser settings. Disabling strictly necessary cookies (authentication, CSRF) will prevent you from logging in. Disabling functional cookies means your theme and sidebar preferences won't persist between visits.
No cookie consent banner is presented because all cookies are either strictly necessary for the service to function or are functional preferences — neither category requires consent under GDPR.
