We collect personal data you provide to us, personal data generated through your use of the Service, and personal data we receive from service providers involved in operating the Service.
When you create or use an account, we may process information such as your account and sign-in identifiers, email address, and other information needed to authenticate your account, maintain access, and keep the Service secure.
We use third-party authentication providers to support sign-in, account linking, password reset, and account recovery.
We may collect and store:
We may also generate or store derived information from content you submit in order to maintain character consistency, personalization, conversation continuity, and Service quality. We do not ask you to provide sensitive personal information, and you should avoid submitting information you do not want processed by the Service.
Most in-app content is stored using protective measures designed to reduce unnecessary exposure. However, if you submit a message report, we may retain the report details, related message context, and relevant derived information in a readable form so we can review and handle the report.
If you make purchases or use subscription features, we may collect and store:
We do not receive or store your full payment card number or other full payment details entered directly with app stores, payment providers, or subscription providers.
When you use the Service, we may collect:
We use IP address and related technical information to protect the Service, maintain security, prevent abuse, investigate incidents, and address payment, refund, or similar dispute-handling issues where needed.
If you contact us, we may collect:
Authentication-related emails, such as verification or password reset emails, may be sent through our authentication providers as part of the Service.
We use personal data to provide and operate the Service, manage accounts and access, support chat, character, and personalization features, process subscriptions and related transactions, respond to support requests and user reports, maintain security and reliability, investigate abuse or incidents, comply with legal obligations, and protect our rights and the lawful operation of the Service.
We do not use your personal data to send you marketing communications.
We may disclose personal data to the following categories of recipients:
We do not sell personal data, serve advertising, use third-party advertising SDKs, use third-party crash reporting SDKs, or create advertising profiles about users. Subscription and app store service providers may process purchase, entitlement, account, device, installation, and related technical identifiers as needed to provide billing, subscription management, purchase restoration, fraud prevention, dispute handling, and subscription-related service analytics.
We retain personal data for as long as reasonably necessary for the purposes described in this Privacy Policy, including providing the Service, maintaining security, complying with legal obligations, resolving disputes, and enforcing agreements.
If you delete your account through the Service, your user content and related in-app content are generally deleted as part of the deletion process. Certain account records, transaction records, report records and related review materials, support or abuse-prevention records, and operational logs may be retained for up to 180 days after account deletion. We may retain information for a longer period where required by law or reasonably necessary for disputes, fraud prevention, refunds, chargebacks, or legal claims.
Hibiku AI is offered to users in multiple countries. As a result, your personal data may be processed in countries other than your own, including where our service providers operate, such as the United States.
When personal data is handled across borders, we take reasonable steps designed to protect it and require service providers to handle it in a manner consistent with applicable contractual, security, and legal requirements.
Depending on your location and the nature of your request, you may ask us to:
You may delete your account in the app where that feature is available.
For other privacy requests, please contact us at privacy@hibiku.chat. We may need to verify your identity before completing certain requests.
The Service is intended only for individuals who are adults or who otherwise have full legal capacity under the laws of their jurisdiction.
You must not use the Service if you are under the age of majority or otherwise lack legal capacity to agree to these terms in your jurisdiction.
If we become aware that the Service has been used in violation of this restriction, we may take steps to suspend or terminate the relevant account and delete associated data as appropriate.
We use reasonable administrative, technical, and organizational measures designed to protect personal data against unauthorized access, loss, misuse, alteration, or disclosure. However, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.
We may update this Privacy Policy from time to time. The "Last Updated" date above indicates when this Privacy Policy was most recently revised. If changes are material, we may provide additional notice through the Service or by other reasonable means.
