4. How We Share Information

We do not sell your personal information. We share it only as described below:

  • Service providers (subprocessors): cloud hosting, AI processing providers (Google Gemini, Anthropic, OpenAI, Replicate, fal.ai and Kling), payment processors (Yapp, Xendit and Midtrans), email delivery, and bot-protection services, each acting on our instructions.

  • Legal and safety: when required by law, or to protect the rights, safety, and integrity of the Service, our users, or the public.
  • Business transfers: in connection with a merger, acquisition, or sale of assets, subject to this Policy.

5. Data Retention and Deletion

We retain personal information for as long as your account is active or as needed to provide the Service, comply with our legal obligations, resolve disputes, and enforce our agreements.

Deleting your account

You can delete your account yourself at any time, from Settings under Danger Zone. You can also ask us to delete it by writing to support@cetharia.com.

  • Deletion takes effect immediately: we deactivate the account and sign you out on every device.
  • A 30-day grace period then follows, after which the account and its associated data are permanently deleted or anonymized.
  • You can cancel the deletion during those 30 days by contacting support@cetharia.com.
  • We may keep limited records after deletion where the law requires us to.

6. Data Security

We use technical and organizational measures to protect your information, including encrypted data transport, hashed passwords, access controls, and session management. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

7. Your Rights and Choices

Depending on your location, you may have the right to access, correct, export, or delete your personal information, and to object to or restrict certain processing. You can update most account information directly in the Service or by contacting us. We handle requests in line with applicable law, including Indonesia’s Personal Data Protection Law (Law No. 27 of 2022).

To delete your account, use the Delete Account control in Settings or contact us at support@cetharia.com. Section 5 describes what happens when you do and how long it takes.

8. International Data Transfers

Cetharia is operated from Indonesia, and our service providers may process data in other countries. Where information is transferred across borders, we take steps to ensure it remains protected consistent with this Policy and applicable law.

9. Children's Privacy

The Service is not directed to children under 18, and we do not knowingly collect personal information from them. If you believe a child has provided us with personal information, please contact us so we can delete it.

10. Changes to This Policy

We may update this Privacy Policy from time to time. If we make material changes, we will notify you through the Service or by email and update the date above. Your continued use of the Service after the changes take effect constitutes your acceptance of the revised Policy.
