Calculator inputs

Every Calcendium calculation runs locally in your web browser. The values you enter, such as prices, balances, rates and dates, are not sent to Calcendium's servers. They are not stored by Calcendium or shared with anyone. Reloading or closing the page clears them.

Information stored on your device

If you change the display currency on a calculator, that choice (for example “EUR”) is saved in your browser's local storage so the next calculator uses it too. It never leaves your device, and you can remove it by clearing your browser's site data. Calcendium does not set cookies.

Server and network logs

Like any website, Calcendium is delivered by hosting and network providers. When your browser requests a page, these providers may automatically process technical information, such as your IP address, browser type, the page requested and the time of the request. They use it to deliver the site, keep it secure and prevent abuse. This information does not include calculator inputs. Calcendium is hosted on DigitalOcean App Platform, and its domain is managed through Cloudflare.

Fonts and third-party resources

Fonts and other assets are served from Calcendium's own domain. The only third-party script is Cloudflare's analytics beacon, described below. Pages do not load font or advertising services. Links to external sources open the publisher's website, which has its own privacy policy.

Analytics

Calcendium uses Cloudflare Web Analytics to understand which pages are visited and how fast they load. When a page loads, a small script from static.cloudflareinsights.com reports the page address, the referring page, your browser and device type, your approximate country and page-load performance measurements. It does not set cookies or store anything on your device, it does not follow you across other websites, and Calcendium sees only aggregated statistics, not individual visitors. Calculator input values are never included. Cloudflare processes this data as described in its privacy policy. Content blockers that stop this script do not affect how the site works.

Advertising

Calcendium currently shows no advertising. If advertising is introduced later, this policy will be updated before it goes live, and consent will be requested where the law requires it. Calculator input values will never be shared with advertisers.

Email

If you email Calcendium, your message and address are used only to read and answer it, and are kept no longer than needed for that purpose.

Your rights

Depending on where you live, you may have rights to access, correct or delete personal data, or to object to its processing. Because Calcendium does not collect calculator inputs or run user accounts, it usually holds no personal data about visitors beyond emails they send. To make a request, contact [email protected].

Children

Calcendium is a general-audience site and does not knowingly collect personal data from children.

Changes

This policy will be updated when practices change, and the date at the top of the page will show the latest version.
