Privacy policy
Updated September 23, 2026
Sumifuda Tarot (the site) handles your information only as far as it needs to. This page explains what the site handles and how it is used.
What we handle
The birth date you enter, the other person's birth date for a compatibility reading, the question you write for topics that ask for one, and the topic and tone you choose. There is no field for your name, email address or home address.
Why
This information is used only to work out the cards and to write the reading.
What is sent elsewhere
To write the reading, your birth date, the other person's birth date, your question, the topic and the cards are sent to OpenAI's API. OpenAI has stated that by default it does not use data received through its API to train its models. The site does not share what you enter with anyone else.
The English pages load one heading typeface from Google Fonts, so opening one makes a request to Google's servers. The Japanese pages use only fonts served from our own server. The site is delivered through Cloudflare, which may set a cookie to block malicious traffic.
What we keep
Our server does not store birth dates, questions or readings. To enforce the usage limits, it keeps an irreversible identifier derived from your IP address and a count, for up to two days. To see how many readings are made, it records the time, topic, language and whether the reading succeeded.
Standard server access logs (IP address, time, pages viewed and similar) are kept for troubleshooting and security.
What your browser keeps
To save you typing next time, your birth date and your tone choice are kept in your browser's local storage. This is not sent to our server. Use forget my birth date under the form to remove it. The site itself sets no cookies.
Changes
This policy may be revised when needed. When it is, the updated date on this page changes.
