Privacy Policy
Last updated
Draft for phase 1 — to be reviewed by a lawyer before advertising, analytics or accounts go live.
Summary
- Calculations happen in your browser. The numbers you type are not sent to our servers.
- We store your unit, region and theme preference in your browser's local storage (
dcl_prefs) and your cookie choice (dcl_consent). - We do not sell your personal information.
Information we collect
Information you give us: if you email us, we keep the message and your address to reply. Automatic information: our hosting/CDN provider processes technical data (IP address, browser, pages requested) to deliver and secure the site. With your consent we may use analytics to understand which calculators are useful.
Advertising
We plan to show ads served by Google AdSense. Google and its partners may use cookies or similar technologies to serve and measure ads, and — where you allow it — to personalise them. In the EEA, UK and Switzerland we will use a Google-certified consent management platform (IAB TCF) and no advertising cookies are set before you consent. You can learn how Google uses data at policies.google.com/technologies/partner-sites and manage ad personalisation at adssettings.google.com.
Cookies
See our Cookie Policy for a list of cookies and storage and how to change your choice.
Your Privacy Choices
You can change consent at any time using “Cookie settings” in the footer. We honor the Global Privacy Control (GPC) signal as an opt-out of the sale or sharing of personal information for cross-context behavioural advertising; when GPC is on, ads (once enabled) are requested in non-personalised / restricted data processing mode.
Your rights
Depending on where you live (for example under GDPR/UK GDPR, US state privacy laws, PIPEDA/Quebec Law 25 or the Australian Privacy Act) you may have rights to access, correct, delete or object to processing of your data. Email [email protected].
Children
The site is not directed at children under 13 (16 in the EEA).
Changes
We will update this page and the date above when this policy changes.
