Ovy: sovereignty score and 8 European alternatives

Ovy is an app for iOS and Android that tracks the menstrual cycle and is offered for contraception or fertility planning. It is published by Die Ovy GmbH, a company registered in Hamburg, Germany. Users log their cycle and temperature readings, and a separate Bluetooth basal thermometer sold by the company can send temperature data to the app automatically. The app is distributed through the Apple App Store and Google Play.

As a German company registered in Hamburg, Die Ovy GmbH falls under the GDPR, and its privacy policy states that data is saved on the company's own servers. The policy does not specify where those servers are located. It also names US service providers, such as Google, Mailgun, Klaviyo and Zendesk, and an analytics provider with servers in Ireland, so some personal data reaches US processors. The app is not open source. Organisations with strict requirements should ask the vendor to confirm the server location and the list of processors.

Why digital sovereignty matters with Ovy

Ovy is headquartered in DE and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Ovy scores best on data residency.

Ovy is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Ovy together with your other vendors and gives a total score, a heatmap and the main risk drivers.
