Alkadiet estimates the acid or base load of your food using PRAL, a peer-reviewed nutritional metric. It is a food tracker, not a medical device, and it never shows a pH value.
The short version of the privacy policy: your food log lives on your device and in your own private iCloud. We run no user database and cannot read your log. We display no ads in the app. Optional Meta ad measurement starts only after your consent; you can turn it off in Privacy.
