Ref. PRV-002 / Scope

Whose information this policy covers

This policy applies to personal information that Treasury Quartz Godo Kaisha handles through treasuryquartz.com and through the enquiries and review engagements that start here. The operator is Treasury Quartz Godo Kaisha, 5-8-12 Minami 3-jo Nishi, Chuo-ku, Sapporo, Hokkaido 060-0063, Japan. Under the Act on the Protection of Personal Information (APPI) we are the business operator responsible for the information described below.

We are a small advisory practice, and what we hold about visitors is limited. We would rather list it concretely than describe it in general terms.

Ref. PRV-003 / What We Receive

The information that reaches us

Ref. PRV-004 / Records Shared in a Review

What happens to the material you hand over for a review

A review means working through purchasing records, supplier agreements and stock data. These files can contain names and business contact details of your buyers and of people at your suppliers. We use them only to prepare the report you commissioned, and we ask you to send what the scope needs and no more. Where a name or an email address in a contract has no bearing on the reading, feel free to black it out first.

Each client's records are kept apart. Figures from one company are never combined with another's, quoted to a third party or carried into marketing material of ours.

Ref. PRV-005 / Purposes of Use

Why we use personal information

We do not use personal information for purposes outside this list. If that ever has to change, we will update this page and, where the APPI requires it, ask for your consent first.

Ref. PRV-006 / Sharing

Who else may see it

We do not sell personal information, and we do not hand it to third parties except in the cases below.

We do not currently use subcontractors for review work. If we propose one for your engagement, the proposal will say so and we will ask for your agreement before any record is passed on. Some email or file-storage services keep their servers outside Japan; when your information would be held abroad, we will tell you in the proposal and obtain consent where the APPI calls for it.

Ref. PRV-007 / Retention

How long we keep it

Ref. PRV-008 / Security

How the material is looked after

Files received for a review are held in access-restricted storage and opened only by the person working on that review. Working copies are removed when the retention period above ends. If a leak affects your rights and interests, we will report it to the Personal Information Protection Commission and tell you directly, as the APPI requires.

Ref. PRV-009 / Your Rights

What you can ask of us under the APPI

You may ask us to disclose the personal information we hold about you, to correct, add to or delete it, to stop using it, or to stop providing it to third parties. Please write through the Contact page or to info@treasuryquartz.com. We will confirm who is asking before releasing anything, and we aim to answer within two weeks; if a request needs longer, we will say so and give a date. We do not charge for ordinary requests.

If you are dissatisfied with how we answered, you may also raise the matter with the Personal Information Protection Commission.

Ref. PRV-010 / Cookies

Cookies and similar storage

The detail is on the Cookie Policy page. In short: at the date of this policy the site sets no analytics or advertising cookies of its own, and your consent choice is the only thing it writes to your browser.

Ref. PRV-011 / Changes and Contact
