Privacy policy

Last updated September 22, 2026

About this policy

This policy explains how Arni Labs("we", "us") collects, uses and shares information when you use Katagami, including the website at katagami.ai and its MCP servers (the "service").

Information you give us

  • Account information. When you sign in with Google, we receive your name, email address, profile picture and Google account identifier. We also store the role we assign your account.
  • Content you submit. Styles, images and remixes you contribute, and your answers to our feedback form.
  • Text you submit for AI evaluation. Descriptions and refinements you type into Ask the library and the explore page, and page source you submit to be checked against a design language.

Information we collect automatically

  • Usage information. The pages you view, what you click, the searches you run and any errors you encounter. If you are signed in, we can link this information to your account.
  • Device and connection information. Your browser type, device type and IP address.
  • Connected agents. When you connect an AI agent through our MCP servers, we record which agent you connected, the access you granted it and how often it is used.

How we use information

  • To provide the service, including signing you in and recording who contributed each style.
  • To evaluate the text and page source you submit and return the results.
  • To understand how the service is used, fix problems and improve it.
  • To protect the service, including limiting request rates and preventing abuse.
  • To respond to your requests and contact you about your account.
  • To comply with legal obligations.

How we share information

We do not sell your personal information, and we do not use it for advertising. We share information only as follows:

  • Service providers. Companies that run parts of the service for us: Google for sign-in, Vercel and Railway (with Turso and Cloudflare R2) for hosting and data storage, Cloudflare for network and file delivery, Datadog for analytics and logs, Typesafe for AI evaluation of the text and page source you submit, and OpenAI and Modal for the AI tools that review contributed styles. We share with them only what they need to provide their services to us.
  • Public content. Styles you contribute become visible to other users once we approve them.
  • Legal reasons. When the law requires it, or to protect the rights and safety of our users, the public or us.
  • Business transfers. If Arni Labs is involved in a merger, acquisition or sale of assets, information may be transferred as part of that transaction.

Cookies and similar technologies

We use cookies to keep you signed in and to understand how the service is used, and we keep some preferences, such as your choice of theme, in your browser. You can block or delete cookies in your browser settings, but you will not be able to stay signed in without them. Katagami does not respond to Do Not Track signals.

Data retention

We retain your account information and contributions while your account is active, or until you ask us to delete them. Styles you contributed that we have published may stay in the library after your account is deleted. We retain usage and log data for as long as we need it for the purposes above, and our service providers retain it according to their own retention periods.

Your rights and choices

Signed-in users can revoke connected agents and sign out of all sessions from their account settings. To access, correct or delete your personal information, contact us at info@arnilabs.ai. We respond to requests within 30 days.

Security

We use reasonable technical and organizational measures to protect your information, including encrypted connections. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

International data transfers

Katagami is operated from the United States. Our service providers may process your information in the United States and in other countries.

Children

Katagami is not directed to children under 13, and we do not knowingly collect their personal information. If you believe a child has given us personal information, contact us at info@arnilabs.ai and we will delete it.

Changes to this policy

We may update this policy. We post changes on this page and update the date at the top. If a change materially affects how we use information you have already given us, we will tell you on the site before it takes effect.
