HerFlow Terms of Use
Last updated: September 25, 2026
1. Acceptance of Terms
By downloading, installing, or using HerFlow ("the App"), you agree to be bound by these Terms of Use. If you do not agree to these terms, please do not use the App.
2. Description of Service
HerFlow is a period and cycle tracking application for iPhone and iPad designed to help users track menstrual cycles, symptoms, moods, and related information, and to understand the phases of their cycle. The App also lets a user optionally share their cycle day and phase with partners and loved ones, who can follow along and receive tips on how to offer support. Sharing is controlled by the person whose cycle it is.
3. Medical Disclaimer
HerFlow is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease or health condition.
The information provided by the App is for general informational purposes only and should not be considered medical advice. Always consult with a qualified healthcare provider for medical concerns, family planning decisions, or health-related questions.
Cycle predictions and fertility estimates are based on general patterns and may not be accurate for your individual cycle. Do not rely on HerFlow for contraception or conception planning without consulting a healthcare professional.
4. User Responsibilities
You agree to:
- Use the App only for its intended purpose
- Provide accurate information when using the App
- Keep your device and the App secure
- Not use the App for any unlawful purpose
- Not attempt to reverse engineer, modify, or distribute the App
5. Subscriptions and Payments
HerFlow offers optional subscription plans ("HerFlow People") that provide access to premium features:
- Monthly subscription: Billed monthly
- Yearly subscription: Billed annually
Subscriptions automatically renew unless canceled at least 24 hours before the end of the current billing period. You can manage and cancel subscriptions in your Apple ID account settings.
Payment is charged to your Apple ID account at confirmation of purchase. All payments are processed by Apple and are subject to the App Store's terms and conditions.
The free 7-day trial of People requires no payment and does not turn into a paid subscription by itself. When it ends, People features stop until you choose to subscribe.
6. Intellectual Property
The App, including its content, features, and functionality, is owned by Stefan Dasic, the developer of HerFlow, and is protected by copyright, trademark, and other intellectual property laws. You may not copy, modify, distribute, or create derivative works based on the App.
7. Privacy
Your privacy is important to us. Please review our Privacy Policy to understand how we handle your information. By using the App, you consent to the practices described in the Privacy Policy.
8. Data and Backups
Your cycle history, moods, notes, and settings are stored locally on your device; see the Privacy Policy for the cycle summary stored for sharing. We are not responsible for any loss of data due to device malfunction, app deletion, or other circumstances. We recommend regularly backing up your device.
9. Partner Sync Feature
The Partner Sync feature (shown as People in the App) allows you to share cycle information with others using a random code. It is designed with privacy in mind:
- Random code, not your identity: the synced cycle summary is linked only to a randomly generated code, never to your name, email, or Apple ID
- No personal identifiers: we never ask for names, emails, or other information that could identify you
- You control access: only people you personally give your code to can view your cycle summary, and you can remove the record behind your code at any time by switching off Share my cycle or using Clear all data in the App, or by contacting us
- Limited content: the summary contains your recent period days, cycle and period length, current cycle day and phase, and today's symptom tags; your mood and note are included only on days you choose to share, as described in the Privacy Policy
You are responsible for sharing your code only with trusted individuals. We are not responsible for any consequences of sharing your information with others.
10. Limitation of Liability
To the maximum extent permitted by law, HerFlow and its developers shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to:
- Loss of data or information
- Personal injury or health consequences
- Decisions made based on App predictions
- Any other damages arising from the use of the App
11. Disclaimer of Warranties
The App is provided "as is" and "as available" without warranties of any kind, either express or implied. We do not warrant that the App will be uninterrupted, error-free, or completely secure.
12. Changes to Terms
We may update these Terms of Use from time to time. Continued use of the App after changes constitutes acceptance of the new terms. We encourage you to review these terms periodically.
13. Termination
We reserve the right to terminate or suspend access to the App at any time, without notice, for conduct that we believe violates these Terms or is harmful to other users or us.
14. Governing Law
These Terms shall be governed by and construed in accordance with applicable laws, without regard to conflict of law principles.
