2. Personal Information We Collect

Automatic Collection Tools (Cookies)

The app uses essential cookies to keep you signed in, and PostHog usage-analytics cookies only if you consent. The website stores Google Analytics cookies only if you consent; Vercel Web Analytics is cookie-free visit statistics. You can refuse cookies through the banner or your browser settings.

3. Purpose of Use

4. Retention Period

We retain personal information until the user requests account deletion. Simulation results are retained indefinitely while the workspace is active; workspaces are destroyed upon deletion request. Audit logs are retained for five years. Users can delete their account from the settings page or by email request; after account deletion, data is destroyed without delay except where retention is required by law. Payment and refund records are retained for five years, and support inquiry (consumer complaint and dispute) records for three years, under the Korean Act on Consumer Protection in Electronic Commerce. To prevent repeated free trials, the normalized sign-up email and sign-up IP address are kept after account deletion for three years from sign-up and then destroyed.

Database backups are kept in the Google Cloud Seoul region for 35 days and then deleted automatically. Backup copies of uploaded files are destroyed together when an account deletion is requested.

Destruction method: Electronic files are deleted by a method that makes recovery impossible.

5. Processors (Sub-processors)

We delegate certain processing activities to the following sub-processors. We do not sell or share user personal information for marketing or advertising purposes.

6. AI Data Processing

The core capability of the Service is LLM-based simulation. The following describes the AI processing flow and our principles.

Inputs Sent to AI Providers

Inference vs. Training

AI Providers Used

Right to Object and Limitations

AI inference is essential to the Service, so refusal to consent to AI processing means the Service cannot be used. Users who do not consent to AI processing should not register; users who withdraw consent after registration will have their account deleted by the Company.

Automated Decision-Making (PIPA Art. 37-2)

Simulation results (overall scores, recommended markets, prices, persona intent, etc.) are statistical estimates produced by LLMs and generated automatically without human review. Users have the right to contest results, request a re-run, and — where simulation results materially influence a business decision — request a human review by contacting the Company.

7. Cross-Border Transfer of Personal Information (PIPA Art. 28)

The Company transfers user personal information and simulation inputs across borders as described below. Separate consent is collected at sign-up; users who do not consent cannot use the Service.

Transfer method: API calls over HTTPS channels encrypted with TLS 1.2 or higher. Transfer occurs when the user runs a simulation or writes a Mr. AI chat message.

Right to object: Users may refuse cross-border transfer consent. Because the Service depends on LLM providers located outside Korea, refusing consent makes sign-up and simulation use impossible.

8. Google API Services User Data Policy

For features that connect to Google services (Google Search Console, Google Analytics 4) via Google OAuth, our use and transfer of information received from Google APIs to any other app will adhere to the Google API Services User Data Policy, including the Limited Use requirements.
