Privacy policy

Last updated: October 14, 2026

This is an English translation for reference. If there is any difference between this translation and the Japanese original, the Japanese original prevails.

1. Information we collect

Squads does not require account registration. The app and the embed page do not send or store the data you enter (team names, player names, shirt numbers, positions, etc.) on the operator's servers (for the AI assistant integration, see "4. AI assistant integration (MCP)"). It uses no cookies, analytics tools or ads.

2. Storage in your browser

Formations you create and display settings are saved in your browser's localStorage. They stay on your device and are not sent to the operator or third parties. Clearing your browser data also deletes them.

When you create a share URL, the formation is included in the URL. Anyone you give the URL to can view its content. Please be careful about whom you share it with.

3. Embedding (iframe)

Squads embedded in other sites displays data received from the embedding site. Saving data on the embedding site is done by that site's operator, and Squads does not store it. The embed page itself stores nothing in the browser.

4. AI assistant integration (MCP)

When you use Squads from an AI assistant such as ChatGPT or Claude (the MCP server at /mcp; see the AI assistant guide), data is handled as follows.

What we receive: only what the AI assistant sends when it calls a tool (team names, manager names, player names, shirt numbers, position names, positions, play titles, movements, etc.). We do not receive your conversation, the assistant's memory or history, files, or account information. There is no sign-up or authentication.
How we use it: only to build the board and return a share URL and a summary to the AI assistant.
Storage and retention: the content is discarded once the response is returned and is not saved in any database or file. The line-up or play exists only inside the returned share URL.
Third parties: we do not share or sell the content to third parties. Cloudflare, which hosts the Service, may process access logs (IP address, time, request details, etc.) while handling the traffic; their retention follows Cloudflare's policies.

Your conversations with the AI assistant and how the assistant handles data are governed by each service's privacy policy (OpenAI, Anthropic, etc.).

5. External services

Stripe: the development support button (see the disclosure under the Specified Commercial Transactions Act) takes you to a Stripe checkout page. Payment details are entered and processed by Stripe; the operator does not receive card information such as card numbers. The operator receives from Stripe the information needed for the payment (name, email address, amount, date and time, etc.) and uses it only to manage payments, respond to inquiries and keep records required by law. It is handled according to Stripe's privacy policy.
OFUSE: the development support menu takes you to a page on OFUSE, a service run by Sozi, Inc. Fan letters and payments are sent and processed on OFUSE; the operator does not receive card information such as card numbers. Through OFUSE, the operator receives the information OFUSE shows to the recipient, such as the content of the fan letter, the sender's display name and the amount, and uses it only to read your message, respond to inquiries and improve the Service. It is handled according to Sozi, Inc.'s privacy policy (in Japanese).
Cloudflare: the Service is hosted on Cloudflare Pages. Access logs may be processed by Cloudflare.

6. Changes to this policy

We may change this policy as necessary. The revised policy takes effect when posted on this page.
