Privacy Policy

No account required

Costlarity doesn't require you to create an account, provide an email address, or log in to use any calculator. All tools are accessible without registration.

Calculator inputs stay in your browser

All calculator inputs and computations are processed entirely in your browser using JavaScript. Your inputs are not sent to any server and are not collected by Costlarity.

Some calculators use localStorage to remember your inputs between visits. This data is stored locally on your device only and is not accessible to Costlarity or any third party. You can clear it at any time by clearing your browser's local storage.

Analytics

Costlarity does not currently use analytics. If analytics are added in the future, this policy will be updated to disclose what data is collected and how it's used. Any analytics would collect only anonymous usage data such as page views — not personal information.

Personal information

Costlarity does not collect, store, or sell personal information. We don't have access to your name, email, location, device identifiers, or any other personal data unless you voluntarily provide it by contacting us directly.

Third-party links

This site may link to external websites. Costlarity is not responsible for the privacy practices of those sites. We recommend reviewing the privacy policy of any external site you visit.

Changes to this policy

If this policy changes, the updated version will be posted on this page with a revised date. We'll make any material changes clear.
