Privacy Policy

Last updated: October 2, 2026

Summary

Lunalia does not collect, store on servers, sell or share any personal data. Everything you enter in the app stays on your device.

Information you enter

The information you log — such as period dates, flow, symptoms, moods, temperature, weight, notes and settings — is stored only on your iPhone, in the app’s private storage. It is never transmitted to us or to any third party. We do not operate servers that receive your data.

No account, ads or tracking

Lunalia does not require an account. It contains no advertising, no analytics and no third-party tracking tools, and it does not track you across apps or websites.

Device backups

If you use iCloud or computer backups for your iPhone, your Lunalia data may be included in those backups. Backups are managed by Apple under Apple’s privacy policy and are not accessible to us.

Notifications

Reminders are scheduled locally on your device. No information is sent to a notification server.

Face ID

If you turn on the app lock, authentication is handled entirely by iOS. Lunalia never has access to your biometric data.

Data export

A CSV file is created only when you choose to export your data. You decide where it is saved or shared.

Deleting your data

You can delete all your data at any time in Settings → Delete all data, or by deleting the app.

Health disclaimer

Lunalia provides estimates based on the data you enter. It is not a medical device, does not provide medical advice and must not be used as a method of contraception.

Children

Lunalia is not directed at children under 13.

Changes

If this policy changes, we will update this page and the date above.
