Is my data uploaded anywhere?

No. All your measurements and profile information are stored exclusively on your device and are never sent to servers or third parties.

What happens if I uninstall the app?

Because there is no cloud backup, uninstalling or reinstalling the app permanently deletes your local data. It cannot be recovered.

Which languages are supported?

English, Turkish, Russian, German, French, Italian and Greek. The app follows your device's system language.

How do PDF exports work?

You get 2 free PDF exports per day. You can watch an ad to earn additional export credits.

How often do ads appear?

Full-screen ads appear approximately every 3–5 measurement saves. They help support development of the free app.

Is Bloodsio Diary a medical device?

No. It is a personal tracking tool only and does not constitute medical advice. Please consult a healthcare professional about your blood pressure.
