Privacy

1. What you type

Values you enter are processed inside your browser only. They are not transmitted to us and not stored by us.

2. Cookies and advertising

This site carries Google AdSense advertising to cover its running costs. Google and other third-party vendors may use cookies to serve ads based on your visits to this and other sites. You can turn off personalised advertising in Google's Ads Settings, and block third-party vendor cookies at aboutads.info.

If you arrive from the European Economic Area, the UK or Switzerland, we ask before any advertising cookie is used. A Google-certified consent management platform puts 「Consent」 and 「Do not consent」 side by side on its first screen, and if you decline, no cookie used for personalised advertising is read or written. Section 5 below sets out the details.

3. Access logs

The site runs on static hosting, and the hosting provider may keep access records (IP address, browser type and so on) for a period under its own policy, for service delivery and security. We do not use those records to identify anyone.

Visit statistics are measured with Cloudflare Web Analytics. It uses no cookies and no local storage, identifies nobody, and only counts how often each page was opened. The always-on display screens carry no measurement either.

4. What stays in your browser

Different screens leave different things behind. The language you chose is kept so the site opens in it next time. Calculators keep the values you entered, and the display-board editor keeps the boards and photos you made, so you can pick up where you left off.

All of it stays in your browser and none of it is sent to a server. Clearing the site's data in your browser removes it.

5. If you are in the European Economic Area, the UK or Switzerland

This section states what the General Data Protection Regulation (GDPR) and the equivalent UK and Swiss laws require us to tell you. It makes no promise different from sections 1 to 4 — it restates the same facts under the headings those laws ask for.

Who processes your data — just-new, which runs this site, is the controller. Reach us at the address at the foot of this page.

What is processed, and on what basis — cookies and device identifiers used for advertising rest on consent (GDPR Article 6(1)(a)). If you decline, no cookie used for personalised advertising is read or written. Access logs kept by the hosting provider for service delivery and security rest on legitimate interests (Article 6(1)(f)). What you type into a tool never reaches us, so there is nothing there for us to process.

Who receives it — information in advertising cookies may go to Google and to the advertising partners you can inspect one by one under 「Manage options」 in the consent dialog. Static hosting and visit counts are handled by Cloudflare. We pass personal data to no one else.

Transfers outside Europe — Google and Cloudflare process data in the United States and elsewhere outside Europe. Those transfers rest on the EU-U.S. Data Privacy Framework or on Standard Contractual Clauses, as each provider states.

How long it is kept — we collect and store no personal data, so there is no retention period on our side. The lifetime of an advertising cookie follows Google's policy and each partner's; access logs follow the hosting provider's.

Your rights — you may request access, rectification, erasure, restriction and portability, and you may object to processing. Since we hold nothing, requests about advertising cookies have to go to Google and the partner that actually holds the data; we can tell you where and how.

Withdrawing consent — the 「Cookie settings」 link in the footer reopens the consent dialog. The law requires withdrawing to be as easy as giving, so that door stays open. Withdrawing does not make the processing before it unlawful.

Complaints — you may lodge a complaint with the data protection authority in the country where you live. Telling us first at the address above means we can look into it.

We make no automated decisions or profiling that produce legal effects for you. This site is not directed at children under 16, and it does not ask anyone's age.
