This is a courtesy translation. The Japanese version of this policy is the authoritative text; if the two differ, the Japanese version prevails.
POROSIS-CARE (porosis-care.com) has no account registration. If you enter test values or records, that content is never sent to our servers. Every calculation and assessment happens inside your own browser.
Information we never hold cannot leak, and cannot be passed to anyone.
None of the following is obtained or stored by this site.
On 8 August 2026 we discontinued account registration, the paid membership, and the photo-reading feature, and retired the database that had been used to store records.
There is no personal information to disclose. We do not pass user information to any third party, including our corporate sponsor — because we do not hold any in the first place.
None. We previously sent photographs to an AI provider in the United States in order to read figures from them, but that feature was discontinued on 8 August 2026. No user information now leaves the country from this site.
This site is not a medical institution. What it offers is not a clinical record but a tool to help your own understanding and your conversation at an appointment. Always consult your own doctor about treatment decisions.
If we change this policy we will publish the change, with its date, on this page. If we ever introduce a mechanism that obtains information, we will say clearly what it does and obtain the necessary consent first.
