# Terms of Use

Last Updated: October 13, 2026

Welcome to PERIOD. ("we," "us," or "our"). By using our mobile application, PERIOD. (the "App"), distributed through the Apple App Store and Google Play Store, you agree to these Terms of Use. Please read them carefully before using the App.

## 1. Acceptance of Terms

By accessing or using PERIOD. you agree to be bound by these Terms. If you do not agree to these Terms, please do not use the App.

## 2. Description of the Service

PERIOD. is a menstrual cycle tracker that helps you log your cycle, track symptoms, and gain insights into the different phases of your cycle. The App also includes an AI-powered assistant that can answer questions about menstruation and cycle health. The App is intended as a personal wellness tool and does not replace professional medical advice.

## 3. No Medical Advice

Important: PERIOD. is not a medical device and does not provide medical advice. The predictions, insights, and AI assistant responses are estimates and general information based on your inputted data. Always consult a qualified healthcare professional for medical decisions, including those related to contraception and fertility. Do not rely on the App for medical diagnosis or treatment.

## 4. Account Responsibility

- • You are responsible for maintaining the confidentiality of your account credentials.
- • You may not share your account with others.
- • You must provide accurate information when using the App.
- • You are responsible for all activity that occurs under your account.
- • You must be at least 16 years old to create an account.

## 5. Acceptable Use

You agree not to use the App to:

- • Violate any applicable laws or regulations
- • Distribute harmful, offensive, or misleading content
- • Reverse-engineer, decompile, or hack the App
- • Attempt to gain unauthorised access to our systems or other users' data
- • Use the AI assistant to generate harmful or inappropriate content

## 6. AI Assistant

The App includes an AI-powered assistant. By using this feature, you acknowledge and agree that:

- • The AI assistant provides general information only and is not a substitute for professional medical advice.
- • Responses are generated by an external AI provider (Google Gemini models via Google Cloud Vertex AI, processed in the EU) and may not always be accurate or complete.
- • You must give explicit consent before data is shared with the AI provider.
- • We are not liable for any actions taken based on AI assistant responses.

## 7. Intellectual Property

All content, designs, trademarks, and functionality of PERIOD. are owned by us and protected by copyright and intellectual property laws. You may not copy, modify, distribute, or create derivative works of the App without our prior written consent.

## 8. Privacy

Your privacy is important to us. Please refer to our [Privacy Policy](https://myperiod.app/privacy) for information on how we collect, use, and protect your data.

## 9. Limitation of Liability

PERIOD. is provided "as is" and "as available" without warranties of any kind, either express or implied. To the fullest extent permitted by law, we are not liable for any direct, indirect, incidental, or consequential damages arising from your use of the App, including but not limited to inaccurate predictions, loss of data, or reliance on AI assistant responses.

## 10. Changes to These Terms

We may update these Terms from time to time. Significant changes will be communicated through the App. Your continued use of the App after any changes constitutes your acceptance of the revised Terms.

## 11. Termination

We may terminate or suspend your access to the App if you violate these Terms. You may delete your account and all associated data at any time via the App's settings.

## 12. Subscriptions (PERIOD. plus and PERIOD. baby)

The basic features of PERIOD. are free. PERIOD. plus (EUR 3,99 per month or EUR 34,99 per year) and PERIOD. baby (EUR 7,99 per month or EUR 54,99 per year) are optional subscriptions. Each starts with a free trial; the store shows its length before you confirm. Subscriptions are sold and billed by Apple (App Store) or Google (Google Play), renew automatically at the end of each period unless cancelled at least 24 hours before renewal, and can be cancelled at any time in your App Store or Google Play account. We never see your payment card details. PERIOD. baby includes everything in PERIOD. plus; switching between the two is settled by the store. Local prices may differ by country and currency. If you stop a subscription, your data stays yours and the free features keep working.

## 13. Governing Law

These Terms are governed by and construed in accordance with the laws of the Netherlands. Any disputes arising from or relating to these Terms shall be submitted to the competent court in the Netherlands.
