Privacy Policy

Takujo Lab ("this site") handles visitor information as described below. This site has no login or registration, and we never ask you to enter personal information such as your name or email address.

1. Analytics (Cloudflare Web Analytics)

This site uses Cloudflare Web Analytics, provided by Cloudflare, Inc., to understand how the site is used and to improve it.

  • This measurement does not use cookies or browser storage, and it does not create identifiers to track visitors (see "5. Advertising" for how advertising uses cookies).
  • It collects information such as the pages viewed, referrer, approximate country or region, browser and device type, and page speed, which is handled as aggregated statistics.
  • We do not use it to identify individuals.

For details on the information collected, see the Cloudflare Privacy Policy.

2. Input saved in your browser

Your input, such as the lands and spells in your deck, is saved in your browser (localStorage) so you can continue next time. It is not sent to this site's servers or to third parties.

You can erase it by deleting site data in your browser settings.

3. Calculations and share URLs

All probability calculations run in your browser, and your input is not sent to a server.

URLs made with "Share this setup" contain your input after the "#". That part of a URL is not sent from your browser to the server, but anyone you share the URL with can see your input.

4. Hosting

This site is delivered using services from Cloudflare, Inc. As part of delivery, technical information such as your IP address is sent to Cloudflare when you visit.

5. Advertising (Google AdSense)

This site uses Google AdSense, a third-party advertising service. Cookies are used to serve ads as described below.

  • Google uses cookies to serve ads on Google's partner websites, such as sites that show Google ads.
  • Third-party vendors, including Google, use cookies to serve ads based on your previous visits to this site or other websites.
  • Google's use of advertising cookies enables it and its partners to serve you appropriate ads based on your visits to this site and other sites.
  • This site does not obtain information that identifies you, such as your name, address, email address, or phone number, through cookies.

How to turn off personalized ads

  • You can turn off personalized ads in Google Ads Settings.
  • You can turn off third-party vendors' cookies for personalized ads at www.aboutads.info.
  • You can also turn off cookies in your browser settings (ads will still appear, but they will not be personalized).

For more on how Google handles information, see How Google uses information from sites or apps that use our services.

Consent for visitors from Europe

For visits from the European Economic Area (EEA), the UK, and Switzerland, we show a message through Google's consent management system and ask for your consent to the use of cookies and similar technologies for advertising.

You can change or withdraw your consent at any time. Select the "Privacy and cookie settings" link at the very bottom of any other page on this site to see the message again (the link does not appear on this page because this page does not load the advertising script).

6. Disclaimer

Calculation results on this site are probability estimates from simulations. They do not guarantee the results of actual games.

We strive to keep the information on this site accurate, but we are not responsible for any damages arising from your use of this site.
