Privacy and safety boundaries
- The Skill changes visual presentation; it does not read, modify, or transmit Codex conversations.
- Uploaded images are used to build the requested theme and are not used for model training.
- Community preview images are derived from the source image, not from screenshots of a user's real Codex window.
- The Skill uses a loopback-only Chrome DevTools Protocol connection while applying a theme. The full limitation and mitigation are documented on the Security page.
- Payment details are processed by Creem as Merchant of Record; GptSkin does not store full card credentials.
