Privacy Policy

1. What this policy is about

2. What data we actually process

• Basic identifiers such as group, room, or user IDs, message IDs, event IDs, and fields required to process a request.
• Group settings such as translation rules, quiet mode, exclusion lists, plan status, last update time, and who updated the settings.
• Usage totals, such as daily aggregated usage for each chat, used to determine plan status and quota.
• Support data when you contact us through LINE 1:1, such as message content, related event details, and necessary support records.
• Billing data when you use paid features, such as payer identifiers, plan, amount, currency, transaction status, and records needed for reconciliation.

3. How real-time translation uses data

• A group message is processed when it arrives and used to produce the translation result for that chat according to its current settings.
• Real-time translation content is not used for other purposes such as advertising, marketing, user profiling, content analysis, or training.
• The real-time translation flow does not write group conversation content into the database and does not maintain a separate conversation-history table for group chat content.
• To keep the service stable and investigate issues, the system may still keep necessary request or error-handling records, but that is not a conversation database.

4. What data is stored

• Group settings and plan data are stored because the system needs to know how each chat should be translated, whether quota is available, and when a plan expires.
• Daily usage stores totals only. It does not store every group message.
• If you contact support through LINE 1:1, those messages may be stored as support records so we can reply, track progress, and investigate problems.
• Billing data is stored to create subscriptions, verify payment results, activate plans, and handle reconciliation.

5. Data sharing and usage boundaries

• Data is shared with necessary service providers only when needed to deliver translation, send messages, save required settings, or process billing.
• We do not sell, rent, or exchange your personal data, and we do not provide group conversation content to unrelated third parties.
• We may process or provide relevant data only when legally required, when a lawful authority requests it, or when necessary to protect users and service security.
• If you want to ask about access, correction, or deletion of stored data, you can contact us through LINE 1:1, but some billing or security records may still need to be retained where required.
