Privacy Policy

Effective date: 5 July 2026

This policy explains what information AquaCalcs (“we”, “this site”) does and does not collect, and how third-party services used on the site handle data. The short version: our calculators run entirely in your browser and we do not ask for, or store, your personal information; advertising and analytics partners may use cookies as described below.

Calculator inputs

Everything you type into a calculator on this site is processed by JavaScript in your own browser. Calculator inputs are not transmitted to our servers, stored, or shared. Reloading a page discards them.

Advertising and cookies

This site displays advertising served by Google AdSense to cover its running costs.

• Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website and other websites.
• Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visits to this site and/or other sites on the Internet.
• You may opt out of personalised advertising by visiting Google Ads Settings, or opt out of a range of third-party vendors’ cookies at www.aboutads.info.
• Where required (for example in the EEA and UK), a consent message will be shown before advertising cookies are set, and non-personalised ads may be served to users who decline.

For more detail on how Google uses data from sites that use its services, see policies.google.com/technologies/partner-sites.

Analytics and server logs

Like most websites, our hosting provider (Cloudflare) records standard technical logs — IP address, user agent, pages requested — for security and performance purposes. If we add privacy-respecting aggregate analytics in future, this policy will be updated to describe them. We do not use analytics that build individual profiles.

Cookies we set ourselves

None. AquaCalcs does not set first-party cookies, does not use local storage to track you, and has no accounts or logins.

Children

This site is a general-audience reference and does not knowingly collect personal information from anyone, including children under 13.

Links to other sites

Pages occasionally link to external resources. We are not responsible for the content or privacy practices of other websites.

Changes and contact

If this policy changes, the effective date above will be updated. Questions about privacy on this site can be sent to stevenjia93@gmail.com.
