Last updated 18 September 2026. This policy covers silver-helper.shop only.
This site is a set of static reference pages. There are no accounts, no comment forms, no newsletter and no payment on this site. We do not ask you for personal information and we do not sell personal information.
Like almost every website, the server keeps standard technical request logs: the page requested, the date and time, the HTTP status code, the referring page and the IP address of the requesting client. Those logs are used to keep the site running, to detect abuse and to see which pages are actually read; they are kept for a limited period and are not combined with any other information about you.
Advertising on this site is served by third-party vendors, including Google. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the internet.
You can opt out of personalised advertising by visiting Google's Ads Settings (https://www.google.com/settings/ads). You can also opt out of some third-party vendors' use of cookies for personalised advertising at https://www.aboutads.info/choices/ and https://www.youronlinechoices.com/.
Where the law requires it, a Google-certified consent management platform asks for your consent before advertising cookies are used, and lets you change or withdraw that consent at any time. If consent is refused or withdrawn, ads are served in a non-personalised form.
This site is hosted on a server in Japan, so requests pass through Japan and the request logs described above are stored there.
This is a general-audience reference site about working days and public holidays. It is not directed at children under 13 and does not knowingly collect information from them.
You can block or delete cookies in your browser settings; the reference pages and the calculators on this site keep working without them. If the law where you live gives you rights of access, correction, deletion or objection over personal data, write to the address below and we will answer within a reasonable period.
If the way this site handles data changes — for example if a new analytics or advertising provider is added — this page will be updated and the date at the top will change.
