A period app that doesn’t read your data

Your period, your contraception, your intimate life: this is some of the most personal information there is. It deserves real protection.

Highly sensitive data

A cycle tracking app knows when you have your period, whether you’re late, whether you take the pill, your symptoms and your mood. This information can reveal a wish for a baby, a pregnancy or a health problem. Many free apps make money from advertising or by sharing data with other companies.

End-to-end encryption, in practice

With Ragnagna, everything you log is encrypted on your phone, with a key derived from your password, before it is sent. The server only keeps unreadable data. Neither the Ragnagna team, nor the host, nor anyone else can read it.

What Ragnagna doesn’t do

• No ads.
• No trackers, no outside audience measurement tools.
• No selling or sharing of data.
• Meal photos are shrunk and encrypted on your phone; no online AI looks at them.

What stays in your hands

• A personal recovery key to get your data back if you forget your password.
• A backup you can export to your phone.
• Permanent deletion of your account and all your data, in one go.

Ragnagna is not a medical device and does not replace advice from a health professional. If in doubt, talk to your doctor, midwife or gynaecologist.
