Privacy Policy
Short version: what you type into a calculator never leaves your device.
Last updated: 2026
Who we are
CalcuLane (calculane.com) is operated by WadihFree OÜ, registered in Estonia. For anything in this policy, contact hello@calculane.com.
What you type into a calculator
Nothing. Every calculator on this site runs entirely inside your own web browser using JavaScript. The loan amounts, rates, measurements and any other figures you enter are never transmitted to us, never stored on a server, and never shared with anyone. Close or refresh the page and they're gone.
Information collected automatically
Like almost every website, our hosting provider records basic technical information when a page is served — IP address, browser type, the page requested and the time. This is used to keep the site running and secure, and to spot abuse. We do not use it to try to identify you.
Cookies and local storage
- Your theme choice. If you switch between light and dark mode, that preference is saved in your browser's local storage. It stays on your device and is never sent to us.
- Analytics. If and when we use a privacy-respecting analytics tool, it will be to count page views and understand which calculators are useful — never to build a profile of you.
- Advertising. This site is supported by advertising. Ad providers, including Google, may use cookies or similar technologies to show and measure ads. Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalised Google advertising at Google Ads Settings, or opt out of third-party vendors' use of cookies at aboutads.info.
Your rights
As we operate from Estonia, the EU General Data Protection Regulation (GDPR) applies. You have the right to ask what personal data we hold about you, to have it corrected or deleted, to object to processing, and to complain to your local data protection authority. Because we deliberately collect so little, in most cases there is simply nothing held about you. To make a request, email hello@calculane.com.
Children
CalcuLane is a general-audience reference site and is not directed at children. We do not knowingly collect personal information from children.
Links to other sites
Some pages link to other websites. We're not responsible for their content or their privacy practices, and we'd encourage you to read their policies before sharing anything with them.
Changes to this policy
If this policy changes, the updated version will be posted on this page with a new date at the top. Substantial changes will be noted clearly.
