Privacy Policy

Kioku (“we,” “our,” or “us”) is operated by Jishu Labs. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our AI-powered decision and context memory platform at kioku.jishulabs.com (the “Service”). We are committed to protecting your privacy and the confidentiality of the decisions you record and the context you capture.

We collect the following types of information:

• Account information: Email address and password when you create an account.
• Decision records: The decisions, context, reasoning, alternatives, and consequences you capture, stored in your personal, encrypted workspace.
• Linked context: The Slack threads, GitHub PRs, meeting notes, and manual entries you connect to a decision, along with the search index Kioku builds from them.
• Usage data: Number of decisions captured, projects used, source integrations connected, and feature usage patterns.
• Billing data: When you subscribe to Pro, Stripe processes your payment details. We never store full card numbers.
• Device information: Browser type, operating system, and IP address for security and analytics purposes.

• To provide and maintain the decision capture Service
• To capture your decisions, link related context, and build a semantic search index
• To maintain your decision timeline, history, and project spaces
• To process subscription payments and manage billing through Stripe
• To communicate important service updates and security notices
• To enforce usage limits (for example, the free-tier monthly decision cap)
• To improve the accuracy and quality of our search and context linking

The privacy of your decisions and the context you capture is our top priority. Everything you record and everything Kioku links is scoped to your account and stored encrypted at rest. We never share your decisions or context with other users, use them to train AI models, sell or license them, or make them publicly accessible. You can delete any decision, or your entire history, at any time through Settings.

Your data is stored securely using Supabase with Postgres, protected by Row-Level Security (RLS) policies that ensure only you can access your own decisions and context. Data is encrypted at rest and transmitted over TLS. We retain your data for as long as your account is active. You may export your decisions at any time, and you may request complete account deletion — which removes all associated data permanently.

We use the following third-party services to operate Kioku:

• Supabase: Authentication, Postgres database, and application storage.
• Stripe: Subscription billing and payment processing for Pro plans.
• AI model providers (Anthropic, OpenAI): For embeddings that power semantic search across your decisions and context. Content is sent securely via API and is not retained by the provider for training.
• Netlify: Hosting and production web infrastructure.
• Resend: Transactional email such as account and security notices.

The full, current list is available on the Sub-processors page.

You have the right to access your personal data, export your decisions, correct inaccurate information, delete your account and all associated data, and opt out of non-essential communications. To exercise these rights, visit Settings or contact us at the email below.

We use essential cookies only — for authentication and session management. We do not use advertising or tracking cookies, and no third-party tracking scripts are loaded on our platform. For details, see our Cookie Policy.

We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the new policy on this page and updating the “Last updated” date. We encourage you to review this page periodically.
