4. Third-Party Services

Paddle (merchant of record) processes payments and manages subscriptions. Their privacy policy applies to payment data: paddle.com/legal/privacy.

Cloudflare hosts our registry API and marketplace website. Standard Cloudflare infrastructure logging applies.

MCP plugins you install may connect to external services (email providers, calendar services, etc.) as configured by you. Each plugin's data access is declared in its manifest and enforced by the Sidereal sandbox.

5. Data Storage

License tokens are stored locally on your device in the Secure Enclave (or software-equivalent encrypted storage). We store license records on our registry infrastructure (Cloudflare Workers KV) for validation purposes.

6. Your Rights

Under Australian Privacy Act 1988, you have the right to access, correct, or delete personal information we hold. Contact [email protected] to exercise these rights.

7. Changes

We may update this policy from time to time. Material changes will be communicated via the application or email.
