Introduction
This Cookie Policy explains how Cloudpen uses cookies and similar tracking technologies on cloudpen.dev and its subdomains. It should be read alongside our Privacy Policy.
What are cookies?
Cookies are small text files placed on your device by a website when you visit it. They are widely used to make websites work efficiently, remember your preferences, and provide usage information to site owners.
Alongside traditional cookies, we also use localStorage and sessionStorage in your browser to store editor preferences and session state that does not need to be sent to our servers on every request.
Types of cookies we use
Essential cookies (always active)
These cookies are strictly necessary for the platform to function. They cannot be disabled as the service cannot be provided without them.
- Session authentication — keeps you logged in across page loads.
- CSRF protection — prevents cross-site request forgery attacks.
- Load balancer affinity — routes your requests to the same server during a session.
- Cookie consent record — stores your cookie preferences.
Functional cookies (opt-in)
These remember your preferences to improve your experience. Disabling them won't break the service, but you may lose your settings between visits.
- Editor theme preference (dark/light).
- Sidebar layout and panel sizes.
- Recently opened projects.
- Preferred language/framework defaults.
Analytics cookies (opt-in)
These help us understand how the platform is used so we can improve it. All analytics data is anonymised before storage and is never linked to individual users.
- Page visit counts and navigation flows.
- Feature usage frequency.
- Error rates and performance metrics.
Advertising cookies
We do not use advertising or tracking cookies. We do not work with advertising networks or data brokers, and we never place cookies that track you across other websites.

Payment processing. Sets cookies during checkout to prevent fraud and remember payment state. Only active on payment pages.
Provides DDoS protection and CDN. May set a short-lived security cookie (_cf_clearance) to verify human visitors.
Anonymous usage analytics — only if you opt-in to analytics cookies. IP anonymisation is enabled.
