Terms of Service

Lunarosa is a period tracking application that helps you monitor your menstrual cycle, log symptoms, and receive predictions about your cycle.

We offer:

• Free tier: Basic period tracking, predictions, and calendar view
• Premium tier: Advanced features including symptom tracking, fertility predictions, and detailed insights

Lunarosa is available as a Progressive Web App (PWA) that works in your browser and can be installed on your device.

Lunarosa is NOT a medical device and does NOT provide medical advice.

The predictions and information provided by Lunarosa are estimates based on your logged data. They are not diagnoses, medical opinions, or treatment recommendations.

Always consult a qualified healthcare professional for any medical concerns, health decisions, or questions about your menstrual health.

Using Lunarosa does not establish a doctor-patient or healthcare provider relationship.

Do not rely on Lunarosa for:

• Contraception or pregnancy prevention
• Fertility treatment decisions
• Diagnosing health conditions
• Any medical decisions

All your health data is encrypted. Your period dates, symptoms, and notes are encrypted on your device before being stored on our servers.

We absolutely cannot read your data. Lunarosa uses zero-knowledge encryption. Your data is encrypted with a key derived from your PIN that only you possess. Our servers only store encrypted data that is meaningless without your key.

If you lose your PIN and recovery key, your data is permanently lost. We cannot recover it. We cannot reset it. This is intentional - it's the only way to guarantee that no one (including us) can ever access your private health information.

You are responsible for:

• Remembering your PIN or storing it securely
• Saving your recovery key in a safe place (written down, password manager, etc.)
• Never sharing your PIN with anyone

By using Lunarosa, you agree to:

• Provide accurate information when creating your account
• Keep your account credentials secure
• Not misuse the service or attempt to access others' data
• Not use the app for any illegal purposes
• Be at least 13 years old (or have parental consent)

You must be at least 13 years old to use Lunarosa.

If you are under 18, you should have permission from a parent or guardian to use this app.

We comply with COPPA (US), LGPD (Brazil), and other applicable child protection regulations.

Lunarosa is provided "as is" without warranties of any kind, either express or implied.

We are not liable for:

• Data loss due to lost encryption keys
• Inaccurate predictions or cycle estimates
• Health decisions made based on app information
• Service interruptions or technical issues
• Any damages arising from use of the service

Our maximum liability is limited to the amount you paid for premium services, if any.

By using LunaRosa and providing your mobile phone number, you agree to receive SMS and WhatsApp messages from LunaRosa for the sole purpose of account authentication. Message and data rates may apply. You can opt out at any time by replying STOP or contacting support.
