YAZIO is a consumer app for tracking food, fitness and fasting. According to the vendor's website, it offers AI-assisted food logging, intermittent-fasting timers, recipes and synchronisation with fitness trackers. The service is delivered as a mobile app and through the vendor's website.
The operator is YAZIO GmbH, based in Erfurt, Germany. The privacy policy says the IT infrastructure is provided by dogado GmbH in Dortmund, without naming the server region, and that transfers to the United States rely on the EU-U.S. Data Privacy Framework or standard contractual clauses. Several named service providers are based in the United States, including Zendesk and Meta. For a European organisation, the main sovereignty question is therefore the chain of sub-processors rather than the operator's seat. The policy does not name a parent company or shareholders.
