Browser storage
Calculator values are processed in your browser. Depending on the features you use, this site stores display preferences, recently viewed pages, saved pH presets, and cached exchange-rate data in local storage. A temporary session-storage value prevents a repeated page reload, and a first-party cookie stores the navigation sidebar state.
Google advertising and consent
Google’s certified consent management platform displays Google’s consent message for advertising consent using the IAB Transparency and Consent Framework (TCF). Google and its advertising partners may use cookies or similar technologies according to their policies and the choices recorded through that message.
We do not store calculator inputs on our servers.
