Privacy Policy

What data is processed

If Google login is used, the service processes only the minimum identifiers needed for authentication and session continuity. This may include an email address and a provider-side OAuth identifier.

If a user registers an API key for AI use, the key may be stored in protected form together with minimal related metadata needed to support account-based functionality.

If a user saves or continues AI chats, chat content and related technical metadata may be stored within the scope needed to provide that feature. Guest-mode calculator storage remains on the user device by default.

Why the data is processed

The service processes information needed for login, session continuity, account identification, and access control. It also uses related information to protect the API key a user has registered and to route AI requests to the selected provider.

When AI chat history is retained, data may be kept so that users can continue previous conversations. Limited technical information may also be used for service stability, error response, and abuse prevention.

How API keys and AI requests are handled

User-provided API keys are encrypted before storage and are not intentionally retained as plaintext in persistent storage. Runtime decryption occurs only when needed to execute a model call requested by the user.

AI features operate under a BYOK model, meaning that users connect and use their own API keys. When a user requests an AI response, relevant prompt and context data may be sent to the external provider chosen by the user, such as OpenAI or Google.

Processing by the external provider is governed by that provider’s own policies and terms. This service considers policy-protected API use important, but users should still review the provider terms that apply to the key they choose to use.

Retention and deletion

Account-linked data is retained only for as long as needed to provide requested features and operate the service. When data is no longer needed, or when deletion is requested, the service proceeds with deletion within a reasonable operational scope.

Users may request deletion of account-linked data through the official contact channel. Browser-stored data created in guest mode may remain on the user device until it is cleared by the user or removed through browser settings.

User rights and contact

Where applicable by law, users may request access, correction, deletion, restriction, objection, or portability regarding personal data. Identity verification may be required before action is taken, and some requests may be limited by legal or technical constraints.

For privacy questions, deletion requests, or security-related inquiries, contact sicpseoul@gmail.com. The operator may ask for minimum identifying details needed to process the request accurately.
