Privacy Policy
Last updated: August 7, 2026
We care about your privacy. This policy explains how Suminoir collects, uses, stores, shares, and protects your personal information, and the rights you have over it. Please read it carefully before using the Service; by using the Service you consent to the information practices described here.
1. Scope
This Privacy Policy applies to your access to and use of Suminoir's products and services through our website and related clients. It does not apply to third-party websites or services reached via links from our Service, which are operated by those third parties under their own policies. By registering for or using the Service, you confirm that you have read, understood, and agreed to this policy.
2. Information We Collect
We collect information under the principles of legality, legitimacy, and data minimization, including: Account information (the email address and login password you provide at sign-up — passwords are stored encrypted and we cannot read them in plaintext — as well as your display name and avatar); Content information (the prompts you enter and the images or assets you upload when using generation and chat features, together with the works generated from them); Usage and log information (your generation and conversation records, credit transactions, activity logs, and access times and pages); Device and technical information (your IP address, browser type and version, operating system, and device identifiers, collected to keep the Service secure and stable).
3. How We Use Your Information
We use the information we collect to: provide, maintain, and improve the Service and process your generation and chat requests; calculate and settle credits and manage your membership and account; protect account and system security and detect and prevent abuse such as bulk farming, account theft, and attacks; carry out content-compliance moderation as required by law; send you service notices, security alerts, or product information you may be interested in where you have consented (you can opt out at any time); and handle your inquiries, feedback, and complaints.
4. AI Content Processing
To provide AI generation services, we process the prompts you enter, the assets you upload, and the content that is generated. To complete a generation, your prompts and related assets may be transmitted to third-party AI model providers for computation. Please note: we do not use your prompts, inputs, or generated content to train our own models without your explicit consent. To keep the platform compliant and content safe, we may review generated content where necessary. Your works are private to you by default and are not publicly displayed or used for purposes beyond those described in this policy.
5. Cookies & Similar Technologies
We use cookies and browser local storage to keep you signed in, remember your preferences (such as language and theme), and help us analyze and improve the Service. You can manage or clear this data through your browser settings, but disabling it may affect some features.
6. How We Share Information
We value your personal information and do not sell or rent it to third parties without your consent. We share only the necessary information in the following cases: With service providers — to operate the Service, we share necessary information with third parties that provide cloud storage, databases, email delivery, error monitoring, analytics, human verification, and AI model computation, and we require them to keep it confidential and process it only to provide services to us; For legal reasons — where required by law or by judicial or administrative authorities, or to protect the rights, safety, or property of us and our users; For business transfers — in a merger, acquisition, reorganization, or asset transfer, your information may be transferred as part of the transaction, and we will require the successor to remain bound by this policy or seek your consent again.
7. Data Storage & Cross-Border Transfer
We take reasonable measures to store your information. Your information may be transferred to, stored in, and processed on servers in different countries or regions. Wherever it is stored, we protect your information using the safeguards described in this policy.
8. Data Retention
We retain your personal information only for as long as necessary to fulfill the purposes described in this policy, and keep related records for the periods required by law. When the retention period expires, or you cancel your account or withdraw consent, we will delete or anonymize your personal information, except where the law requires otherwise.
9. Data Security
We use industry-standard technical and organizational measures such as encrypted transmission and access controls to protect your information against unauthorized access, disclosure, alteration, or destruction. However, please understand that no internet transmission is completely secure; keep your account and password safe. In the unlikely event of a personal-information security incident, we will notify you and take remedial measures in accordance with the law.
10. Your Rights
You have the right to access and correct your account information, request deletion of your personal information or cancellation of your account, change or withdraw consent you previously gave, and request a copy of your personal information for export. To exercise these rights, please contact us using the details below; to protect your account, we may need to verify your identity first.
11. Protection of Minors
The Service is intended primarily for adults. If you are a minor under 18, please read and agree to this policy with the involvement and guidance of your guardian before using the Service. We do not knowingly collect personal information from minors; if we learn that we have collected such information without guardian consent, we will delete it promptly.
12. Third-Party Links
The Service may contain links to third-party websites or services that we do not operate or control. We are not responsible for their privacy practices, and we recommend that you review their privacy policies before use.
13. Changes to This Policy
We may update this Privacy Policy from time to time. For material changes, we will notify you through an on-page notice or other appropriate means. The updated policy takes effect when published; your continued use of the Service after an update means you accept it.
