Calculator and planner data

The daily calculator sends your inputs to our server so it can return an estimate. We do not deliberately store those inputs on the server.

Your device stores your dated drink entries, latest calculated target, custom drinks, tracker history, saved routines, race draft and sweat tests with any labels or conditions you enter. It also stores your display and privacy choices.

The label, fuel, cost, bottle, route and race tools do their calculations in your browser. If you open a GPX route file, your browser reads it locally. HydrateWise does not upload the file. Refreshing the fuelling rehearsal page clears its notes, so print or download a copy if you want to keep them. You control what you do with any downloaded race cards, calendar files or other records.

Optional weather lookup

If you choose to use current weather, your browser asks to use your location. It sends the coordinates directly to Open-Meteo for the temperature and humidity. The coordinates do not go to our server or stay in your browser storage.

Your device may keep the weather results for up to six hours. You can enter conditions yourself or skip the weather adjustment. Open-Meteo’s privacy terms apply to the lookup.

Optional analytics

Google Analytics starts only if you allow it. Google may then collect information about your device, approximate location, pages you view and actions such as completing a calculation, downloading a resource or following a product link.

We leave calculator inputs, results, notes and local history out of analytics. We also remove query strings and fragments from page URLs and referrers, including the details in shared planner links. Analytics does not run in local previews or in the embedded calculator.

Analytics may set cookies with names beginning _ga, typically kept for up to two years. You can withdraw your consent on the Privacy preferences page. This stops collection immediately and removes the site’s analytics cookies we can access. Use your browser settings to clear any site data that remains.

International processing and retention

Google may process analytics data outside the UK under its applicable transfer safeguards. Google controls its analytics retention and processing as described in its privacy documentation. Local planner data remains until you delete it or clear browser storage.

Affiliate links

Amazon links can include an Associate tracking tag. Amazon may process data when you follow a link or make a purchase. Its own privacy terms apply. See our affiliate disclosure.

Your rights

Depending on the data involved, UK data-protection law may give you rights to access, correct, erase, restrict or object to processing, and to withdraw consent. You may complain to the UK Information Commissioner’s Office at ico.org.uk.
