Privacy Policy

Last updated: 8 August 2026

This is a courtesy translation. The Japanese version of this policy is the authoritative text; if the two differ, the Japanese version prevails.

We do not receive your information

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.

1. Information We Do Not Collect

None of the following is obtained or stored by this site.

  • • Your name, email address, telephone number, or postal address
  • • Bone density (DEXA) or blood test results
  • • Medication and injection records, or questions for your doctor
  • • Payment details such as credit card information

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.

2. What Happens to What You Enter

  • • The figures you enter are held in your browser’s memory only while the page is open
  • • They are gone when you close the tab or reload. Nothing is saved to your device
  • • Print what you need and take it with you.The paper in your hand is the record
  • • What you enter is never transmitted anywhere

3. Analytics

  • • We may run anonymous analytics to understand which pages are being read
  • • No information identifying an individual is included
  • • We do not use third-party advertising networks such as Google Ads

4. Disclosure to Third Parties

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.

5. Transfers Outside Japan

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.

6. About the Medical Information

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.

7. Changes to This Policy

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.
