Your work, your data

Privacy Policy

What Sekaiko needs to run the studio, what happens when you use AI tools, and how to reach us about your data.

Last updated October 2026

Overview

Sekaiko is a creative studio for building worlds and making stories and media. This policy explains how we handle information when you visit the site, sign in, use the studio, buy a plan or credits, or connect another service. Contact details are at the end of this page.

Information we handle

Account and profile

When you sign in with Google, we receive information such as your account identifier, name, email address, and profile image. You may also add or change a studio avatar and profile details.

Creative work

We store what you create or upload: worlds, characters, places, items, lore, prompts, conversations, books, scenes, workflows, images, video, audio, 3D media, and related settings and references. AI requests may include the content you select and relevant context from your project.

Usage, support, and billing

We keep records needed to run and secure the service, including generation usage, credit balances, purchases, subscription status, support requests, device and browser details, IP address, access times, and error logs. If you connect a publishing service, we also handle the account details and permissions needed for that connection.

How we use it

  • To authenticate you and provide your studio, projects, media, and account settings.
  • To process the AI generation or publishing action you ask us to perform.
  • To calculate credit use, manage subscriptions, and resolve billing questions.
  • To answer support requests, fix problems, and protect the service from abuse.
  • To meet legal obligations and maintain necessary business records.

When we share it

We share information with providers that help deliver the feature you use. Google handles sign-in. Stripe handles payments; Sekaiko does not store your full payment card number. Hosting and storage providers hold application data and media.

When you request AI generation, the chosen provider receives the prompt, parameters, selected references, and project context needed for that request. Providers available through Sekaiko include services from OpenAI, Anthropic, Google, fal, and Replicate; the provider depends on the tool and model you choose. Each provider has its own data handling and retention terms.

If you connect YouTube or another available publishing service, we use the permissions you grant to carry out actions you request. You can disconnect a service in account settings or revoke access with that provider. We may also disclose information when required by law or needed to protect users and the service.

Cookies and local storage

Essential cookies keep you signed in and protect your session. Sekaiko uses an encrypted session cookie for authentication; the backend access token is handled through that session and server requests, not stored as a separate browser local-storage token. Browser storage may also remember interface preferences, such as your theme or editor settings. Blocking essential cookies can prevent sign-in.

Retention and security

We keep account and creative data while your account is active and as needed to provide the service. After deletion, some information may remain for a limited time in backups, transaction records, security logs, or with providers that processed a request. The exact period depends on the record and applicable obligations. Contact us if you need information about a particular record or a deletion request.

We use access controls, encrypted connections, and other measures to protect data. Connected-service access tokens are encrypted before storage. No online service can guarantee absolute security.

Your choices

You can edit or remove many items in the studio, disconnect connected services, and request account deletion from your settings. Deleting an account ends access, but may not immediately erase every backup, provider copy, or record we must retain. To request access, correction, a copy, or deletion of personal information, email us. Rights and response times depend on the law that applies to you.

For account and data requests, visit Support or email support@sekaiko.com.

International processing

Sekaiko and the providers used for hosting, payments, connected services, and AI generation may process information in countries outside your own. Privacy protections can vary by location. Contact us if you need more detail about a specific service or transfer.

Children

Sekaiko is not intended for children under 13, or under the minimum age required where they live. We do not knowingly collect their personal information. If you believe a child has provided it, contact us so we can investigate and respond.

Changes and contact

We may update this policy when our practices or the service change. We will update the date above and provide additional notice for material changes where required.
