Privacy policy
How this site handles the information of the people who read it.
Operator
This site is operated by Hundreds LLC. The responsible person is Ami Otsuka and the contact address is support@hundreds.co.jp. Details of the operator are set out on Site operator.
Information collected
This site asks readers for no registration and no input. Two things remain:
- The connection log left on the delivery server when a page is opened.
- If you write to the address above, that email address and the body of the message.
Purpose of use
They are used to improve the site and to reply to the mail that arrives. Nothing else.
Analytics and cookies
This site uses Google Analytics (GA4) to know which pages are read and how much. It is provided by Google LLC (United States). The page viewed, the time spent, the approximate region, the device type and the referring page are sent to Google through cookies. Information that names an individual — name, address, email address — is not sent.
What is collected is used only to improve the site. It is not used to serve advertising. Not a single advertising vendor’s measurement tag is installed.
To refuse measurement, either of these will stop it. (1) Disable cookies in the browser settings. (2) Install the Google Analytics Opt-out Browser Add-on distributed by Google (tools.google.com/dlpage/gaoptout). Stopping it changes nothing about reading the articles.
How Google handles this information is set out in its privacy policy.
Where information is sent
Delivery is from servers operated by Vercel Inc. (United States); the connection made when a page is opened reaches their servers. In addition, the analytics information described above is sent to Google LLC (United States). At present these two are the only external destinations.
Advertising
As an Amazon Associate, Hundreds LLC earns from qualifying purchases.
At present there is not a single advertising link on this site. Pages where one appears say “Advertisement” at the top of the page. Whether that appears is decided by machine.
Provision to third parties
Information collected is not passed to third parties, except where the law requires it.
Disclosure, correction and deletion
Requests are received at support@hundreds.co.jp. Corrections to the content of an article go to the same address.
Retention
Mail received is kept in the inbox it arrived in, with no set period. It is deleted on request. The retention period for connection logs on the delivery server follows the hosting provider’s.
When this page is rewritten
This page is rewritten at the moment an analytics tag, an advertising tag or an affiliate link is added. When it is rewritten the revision date below is updated. Past versions are not kept.
