Cookie Policy

1. Scope

This page describes cookies and similar technologies used by the Open-Source-Lab model catalogue and Playground. The Privacy Policy explains the personal information used by both services.

2. Cookies and tracking

The model catalogue does not set first-party cookies. The Playground sets one required, host-only cookie when a guest accepts the Privacy Policy. The cookie remembers the current policy version for up to one year so the guest is not prompted on every visit. It is HttpOnly, Secure over HTTPS, and SameSite=Lax. It is not used for advertising, analytics, or cross-site tracking. Email account signups record acceptance time and policy version with the account instead of relying on this consent cookie.

3. Browser local storage

A previous version kept saved and compared model identifiers in browser local storage. The current version reads those existing values once to transfer them to the saved-list service, then removes them after a successful transfer. If the service is unavailable, the old browser copy remains so it is not lost. New changes are kept in the browser only when a server save fails, and are removed after a later successful save or when you clear saved data.

Local storage is separate from cookies. You can remove it through your browser's site data controls. Removing the old saved values before a successful transfer will delete that browser copy.

4. Saved-list service and IP addresses

The catalogue save feature uses the IP address sent with a page request to associate model selections with a network; it does not set or read a cookie. The Playground uses a keyed IP digest and usage totals to apply guest chat limits of 30,000 characters per rolling 5 hours and 300,000 per rolling 7 days. People sharing a public IP address share those guest limits. See the Privacy Policy for data and deletion details.

5. Third-party resources

The catalogue and Playground serve fonts, icons, and brand images from their own sites. Loading a page does not make a separate font or logo request to Google Fonts or Poe's image delivery network. Model and community links open independent services only when you choose to follow them. If you choose a paid Playground plan, checkout is handled by Stripe on its service; review Stripe's own privacy and cookie information there.

6. Managing browser data

Choose Clear in the catalogue to remove the saved and compared lists associated with your current IP address. Use your browser's site data controls to remove any remaining local storage or cookies. Clearing browser data does not delete data held by an external service you visit.

7. Legal references

The EU ePrivacy Directive addresses storing or accessing information on a user's device. The GDPR applies to personal-data processing where its territorial scope and conditions are met. California's current CCPA statute and regulations took effect on 1 January 2026. Whether a rule applies depends on the user's location and the operator's circumstances.
