Privacy policy

Last updated: 7 November 2026. This policy describes the website and its optional analytics.

Calculator inputs

Calculations run in your browser. The website does not intentionally transmit calculator input values to a SaveWise server or store them in a customer database.

Hosting and technical logs

The website is hosted using Cloudflare. Like other hosting providers, Cloudflare may process technical request data, such as IP addresses and browser information, to deliver and secure the site. See Cloudflare's privacy documentation for details.

Cookies and analytics

We offer optional Google Analytics 4 (Google LLC) to measure page visits and which calculators are used. Analytics scripts are not loaded until you choose Accept analytics. If you reject, we do not load Google Analytics. If you accept, Google may use cookies and collect usage and device information, including online identifiers and approximate location derived from IP address, subject to Google’s processing and retention policies. We do not intentionally send calculator input values, names or email addresses in analytics events. You can change your choice using the Analytics privacy settings button in the footer; rejecting after acceptance stops future analytics collection but does not erase information already received by Google or necessarily remove previously set cookies. You can clear existing cookies in your browser. We do not use Google Analytics advertising features. Hosting-level security and operational technologies may still apply. See Google’s privacy information for details.

Contact

We have not yet activated a public contact mailbox. Please do not submit personal information through calculator fields. A verified contact channel will be published before any enquiries or commercial partnerships are accepted.

Changes

This policy may be updated as the website changes.
