1. What Cookies Are

Cookies are small text files placed on your browser or device when you visit a website. They help websites remember information about your session, preferences, and actions.

2. Types of Cookies We Use

3. Third-Party Cookies and Technologies

Some cookies and similar technologies are provided by trusted third parties we use to operate our business. Depending on your interaction with the Services, these may include:

  • Stripe for secure payment and checkout workflows.
  • Supabase for authentication/session management and backend services.
  • Vercel for hosting and performance delivery.
  • Sentry for diagnostics and error monitoring.
  • PostHog for product analytics.
  • Server-side or cookieless analytics tools for aggregated product and traffic measurement.

Third parties may set their own cookies under their own privacy policies when those services are used.

4. How to Manage Cookies

You can control cookies through browser settings. Most browsers let you:

  • View cookies currently stored on your device.
  • Delete specific or all cookies.
  • Block cookies for specific sites or all sites.
  • Receive a warning before cookies are placed on your device.

We display a cookie banner for non-essential analytics cookies. If you accept, analytics technologies such as PostHog may set analytics cookies. If you decline, we do not intentionally load non-essential analytics cookies, but essential cookies remain active.

If a browser-based analytics script is loaded after you accept analytics cookies, the provider may use its own cookies or browser storage under its own policies.

If you disable essential cookies, parts of the Services may not function properly, including login, secure account features, and checkout.

5. "Do Not Track" and Global Privacy Control

Some browsers provide a "Do Not Track" (DNT) setting. Because there is no uniform industry standard for handling DNT signals, PromptEden does not currently respond to DNT signals in a standardized way.

We do not sell personal information or share it for cross-context behavioral advertising, so there is no sale/sharing to opt out of; we will honor Global Privacy Control (GPC) signals to the extent applicable law requires.

6. Changes to This Cookie Policy

We may update this Cookie Policy periodically to reflect legal, technical, or business changes. We will post updates on this page and revise the "Last updated" date above.
