Cookie Policy

Last updated: March 7, 2026

1. What Are Cookies

Cookies are small text files stored on your device when you visit a website. They help the site remember your preferences, keep you signed in, and understand how you use the service. Stone AI uses a minimal number of cookies — only what's necessary to make the platform work well.

2. Cookies We Use

Here's exactly what we set and why:

Authentication Cookies (Essential)

Set by Clerk, our authentication provider. These keep you signed in and secure your session. Without them, you'd have to log in on every page load. These are strictly necessary and cannot be disabled.

Preference Cookies (Functional)

Store your UI preferences like theme selection, sidebar state, and language settings. These make the app feel like yours. They're stored locally and never sent to third parties.

Analytics Cookies (Performance)

Help us understand how people use Stone AI so we can improve the experience. We collect anonymized usage data — things like which features are popular, page load times, and general navigation patterns. We do not track you across other websites.

Advertising Cookies (Ad-Supported Tiers Only)

On ad-supported tiers (including the Free tier), third-party advertising services may set cookies to deliver relevant ads and measure ad performance. Paid subscription tiers are ad-free and do not receive advertising cookies. See our Privacy Policy for details on advertising data practices.

3. Third-Party Cookies

The following third-party services may set cookies when you use Stone AI:

  • Clerk — session management and authentication
  • Stripe — payment processing (only during checkout)
  • Cloudflare — security and performance optimization

Each of these services operates under its own privacy and cookie policies. We recommend reviewing them if you want the full picture.

4. Managing Cookies

You can control cookies through your browser settings. Most browsers let you block or delete cookies, and you can usually set preferences for specific sites. Here's how:

  • Chrome: Settings > Privacy and Security > Cookies
  • Firefox: Settings > Privacy & Security > Cookies
  • Safari: Preferences > Privacy > Manage Website Data
  • Edge: Settings > Privacy > Cookies

Keep in mind: blocking essential cookies (authentication) will prevent you from signing in to Stone AI. The platform requires these to function.

5. Updates to This Policy

If we change how we use cookies, we'll update this page and the "last updated" date above. For material changes, we'll notify you via email or in-app notification.
