Privacy Policy

Information you provide directly:

• Reading profile: the name or nickname you enter, gender, relationship status, calendar type (solar or lunar, including leap month), date of birth, and (optionally) time of birth.
• Chat messages you exchange with the AI character.
• Account information when you sign in: your email address, display name, and profile image received from Google or Kakao. We never receive your password.

Information collected automatically:

• A one-way hash of your IP address, used to track free usage allowances and to reconnect anonymous test sessions to your account when you sign in. We do not store your raw IP address with your content.
• Service metadata such as timestamps, session status, and AI usage metrics (token counts and processing cost) attached to conversations.
• Device and usage data via cookies and similar technologies (see Section 5), such as browser type, pages viewed, and interactions.

Payment information: payments are processed by Stripe. We receive and store only order details — product, amount, payment status, and a receipt reference — never your full card number or bank credentials.

Derived content: from your inputs the Service generates interpretive data (for example, your saju / Four Pillars chart data and the reading generated for you), which is stored with your reading session. We do not currently collect drawings, images, or other files from you.

• To calculate your saju chart, generate your readings, and power conversations with the AI character.
• To save your readings and chats so you can return to them, and to let you share a reading by link if you choose to.
• To manage free usage allowances, purchased credits, and payments.
• To operate, secure, and improve the Service, prevent abuse, and respond to inquiries.
• To measure and improve our marketing (see Section 5).

Your profile inputs, saju chart data, answers, and chat messages are transmitted to our AI provider — currently Google (Gemini API) — to generate readings and replies. This content is sent for the purpose of generating a response for you. Hosting and data storage are provided by Cloudflare, Inc., with processing primarily in the United States.

We do not sell your personal information for money. We share information only with service providers that help us run the Service, each acting under its own contractual and legal obligations:

• Google LLC — sign-in (OAuth), AI processing (Gemini API), and analytics (Google Analytics).
• Kakao Corp. — sign-in (OAuth).
• Stripe, Inc. — payment processing.
• Cloudflare, Inc. — hosting, database, and file storage.
• Meta Platforms, Inc. (Meta Pixel) and X Corp. (X/Twitter Ads) — advertising measurement, as described in Section 5.
• Authorities or other parties when required by law, or to protect the rights, safety, and integrity of the Service.

If you create a share link, the shared result (and the conversation, if you include it) is visible to anyone who has the link.

We use cookies and similar technologies for session management and to understand and grow the Service. The advertising and analytics tools below are not currently active; if we activate them, we will update this Policy (including the date above). Specifically, we use or plan to use:

• Google Analytics — usage measurement (pages, sessions, events).
• Meta Pixel — measuring the effectiveness of ads on Meta platforms (Facebook/Instagram).
• X (Twitter) Ads pixel — measuring the effectiveness of ads on X.

These tools may set their own cookies and receive event data (such as page visits, checkout starts, or purchases) linked to identifiers they manage. To keep purchase measurement accurate when browser tools are unavailable, we may also send the same conversion events from our servers, together with a hashed (SHA-256) version of your account email address, your IP address, browser information, and ad-click identifiers. This may constitute “sharing” for cross-context behavioral advertising under some U.S. state privacy laws; you can opt out at any time by emailing hi@jak-doo.com, and you can also limit tracking through your browser settings, the Global Privacy Control signal, or the opt-out tools offered by Google, Meta, and X. Your answers, chat messages, and the profile details you enter for a reading (such as name, gender, relationship status, and birth date and time) are never shared with advertising platforms.

• Reading sessions, results, and chats are kept so you can return to them, until you ask us to delete them or we delete them as part of routine data management.
• Purchase records are kept as long as needed for accounting, tax, and dispute-resolution obligations.
• Free-allowance records (hashed identifiers) are kept only as long as needed to enforce usage limits.
• When you request deletion, we delete or de-identify your personal information without undue delay, except where retention is required by law.

You may request access to, correction of, or deletion of your personal information, or a copy of the data you provided, by emailing hi@jak-doo.com. We honor applicable rights under U.S. state privacy laws (including the California Consumer Privacy Act) and other laws that apply to you, and we will not discriminate against you for exercising them. If you are in a jurisdiction with additional rights (such as Korea’s PIPA or the EU GDPR), we will accommodate verified requests consistent with those laws.

The Service is operated from the United States and information is processed and stored primarily in the United States (with content delivery through Cloudflare’s global network). By using the Service, you understand that your information will be transferred to and processed in the United States, which may have different data protection laws than your jurisdiction.

The Service is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided us personal information, contact hi@jak-doo.com and we will delete it.

We use reasonable technical and organizational safeguards — such as encrypted transport (HTTPS), signed session cookies, hashed network identifiers, and access controls — to protect your information. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

We may update this Privacy Policy from time to time. If we make material changes, we will provide notice through the Service and update the date above.
