Privacy & advertising

Our tools calculate in your browser. We do not receive the files, passwords or text entered in their isolated frames. Optional advertising has separate data practices and can be declined.

Tool inputs

Calculator inputs stay in sandboxed frames without network access. They are held temporarily in browser memory while the page is open. We do not offer accounts, save tool history, or upload selected files. Copying a result puts it on your device clipboard only when your browser allows it.

Hosting and access information

Cloudflare delivers the site and may process request information such as IP address, user agent and security logs to provide hosting and protect its network. See Cloudflare's privacy policy. Static hosting does not mean network requests are anonymous.

Optional Monetag advertising

If you choose Allow optional ads, advertising code from Monetag and its partners can run in the surrounding page. Formats may include popunder tabs after interaction, in-page push-style ads, vignette overlays, and browser notification subscription invitations. Ads may process IP address, device identifiers, browser information, referrer and interactions, or use cookies or similar storage according to their policies. A notification subscription also requires your browser's separate permission.

Read Monetag's privacy policy and Monetag's opt-out information. Sponsored links, if present, are clearly marked and open only when you choose them.

Your choices

The advertising choice applies to every visitor in the same way. Declining does not reduce tool access. We store the choice and its time in first-party local storage for up to 180 days. If storage is unavailable, it applies only to the current page. Withdrawing optional advertising reloads the page to stop previously loaded ad scripts.

Change advertising choice

Blocking optional advertising here does not revoke an existing browser notification subscription. You can remove the site's notification permission in your browser's site settings. Third-party cookies already set can be removed through browser controls or the provider's opt-out tools.

Paid campaign parameters

A campaign may use parameters to identify its source. Canonical URLs exclude those parameters. We do not collect a private analytics database on this static site. Ad-network reporting remains subject to the ad partner's policies.

Limits and changes

Extensions, a compromised browser or device, and the websites opened by advertisements are outside the isolated tools' protection. This notice describes the launch implementation as of 21 October 2026. Review it again if you use new features.
