Privacy Policy

Last updated: 2026-11-11

MewMewo ("we") respects your privacy. This policy explains what information is collected when you use this website.

Calculator inputs

The numbers you type into our calculators are processed in your own browser. They are not sent to our servers. Your inputs may appear in the page address (URL) so that you can share or bookmark your results, and your unit preference is stored in your browser's local storage.

Advertising

We show ads to keep the site free. Third-party advertising partners (which may include Adsterra, Monetag and, in the future, Google AdSense) may use cookies, web beacons and similar technologies to serve ads based on your visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and/or other sites on the Internet. You may opt out of personalized advertising by visiting Google Ads Settings or www.aboutads.info.

Analytics and logs

Our hosting provider may keep standard server logs (such as IP address, browser type and pages visited) for security and performance. We may use privacy-friendly analytics to understand which pages are useful.

Children

This site is not directed at children under 13 and we do not knowingly collect information from children.

Your rights

Depending on where you live (for example under GDPR or CCPA), you may have rights to access or delete personal data. Because we do not ask for personal data, we usually hold none about you; contact us with any request.

Changes

We may update this policy and will change the date above when we do.
