6-2. Special Handling of Palm Images
Images uploaded for palm readings (photographs of the palms) are handled as follows in accordance with Article 22 of Japan's Act on the Protection of Personal Information (APPI).
- Consent: Consent to retaining the images is required. The reading cannot begin if you do not consent.
- Data stored: Original right- and left-hand images, cropped palm images for analysis, extracted features, reading text, and overlay information
- Retention period: 30 days after the reading, or until the user deletes the data
- Purpose: Only to generate the reading result and allow the user to review their own previous reading results
- External transmission: Palm images, cropped images, features, and information needed to generate reading text may be sent to the Google Gemini API or Anthropic API for feature extraction, reading-text generation, and full-report generation.
- Third-party disclosure: Except for transmission to the service providers described above, we do not sell, publish, or share palm images.

6-3. Handling of the Feng Shui Structured Beta
In the public beta of the Feng Shui reading, users enter information by selecting items describing the condition of their home, which are matched against fixed rules and prewritten reading text. We do not upload images, ask for an address, or automatically obtain location information. We also do not use map images or transmit information to external AI services.
The reading result stores the selected checklist items, type of residence, reading theme, result text, and purchase status. Room photographs, floor plans, map images, addresses, latitude, and longitude are not stored.
6-4. Use of Data for Machine Learning (Optional Consent)
In the future, to improve the accuracy of palm readings, the Service may reuse palm images and feature data that have been anonymized (with identifying characteristics removed) as training data for its own models. This use is based on optional consent, and users choose whether to consent through a checkbox when starting a reading.
How to withdraw consent: To withdraw consent to machine-learning use, delete the relevant reading result by selecting "Delete this reading" on the result screen. Deletion permanently removes all data, including images in Storage and features and reading text in the database, and excludes that data from subsequent machine-learning use.
6-5. Handling of Report Data
The Service provides channels for reporting problematic content in AI reading results, consultation chat responses, palm readings, fortune-teller profiles, landing pages, services, and reviews. When a report is submitted, the target ID, reason, optional comment, reference URL, content snapshot, logged-in user ID, and related information are stored as a support record. This information is used to review content, respond to inquiries, prevent misuse, and make operational decisions such as restricting display.
