Monday Fertility (“we,” “our,” or “us”) is part of the OTO Family of companies. We are committed to protecting your privacy and safeguarding your personal and health-related data. This Privacy Policy explains how we collect, use, and protect your information when you visit our website, use the Monday Fertility app, or connect an OTO wearable device.
Monday Fertility is a health and technology company focused on helping people understand and optimize their fertility through data-driven insights. Our products and services are powered by OTO Fertility Technology, which provides medical-grade analytics and secure cloud infrastructure for the collection and interpretation of physiological data.
As part of the OTO Family, Monday Fertility works closely with OTO Health Technologies Inc. (“OTO”), which acts as our technology and data processing partner. OTO maintains strict security and privacy controls that meet international healthcare data protection standards.
We collect and process information in three main categories:
Name, contact details, and account information
Medical or wellness information you choose to share
Communication preferences and feedback
Device type, operating system, IP address, and browser type
Website or app usage data (pages viewed, time spent, features used)
Cookies and tracking technologies (see Section 8)
When you use the OTO Fertility wearable or connect it through the Monday Fertility app, the device securely captures physiological and biomarker data, which may include:
Heart rate, heart rate variability (HRV), temperature, and breathing rate
Sleep quality and recovery metrics
Stress response indicators and fertility-related biomarkers
This information is encrypted, pseudonymised, and transmitted to OTO’s secure servers, where it is processed under strict medical-grade data protection standards.
Your data is used to:
Provide personalised fertility insights and recommendations
Display your health trends within the Monday Fertility app
Support clinical consultations (only with your consent)
Improve our products through anonymised analytics and research
Comply with regulatory and data-protection obligations
We do not sell or rent any personal or health data to third parties.
Your physiological and fertility data are treated with the highest standards of care.
Medical-grade Security: All data transmitted from the OTO wearable is end-to-end encrypted (TLS 1.2 or higher) and stored in encrypted databases that meet or exceed HIPAA (U.S.) and PIPEDA (Canada) privacy requirements.
Controlled Access: Only authorised personnel within OTO and Monday Fertility who require access to support your care can view identifiable data, and all access is logged.
Pseudonymisation: Your biomarker data is separated from personally identifiable information wherever possible.
Data Sovereignty: Data is stored on secure servers located in Canada (or another jurisdiction with equivalent protection) and is not transferred internationally without adequate safeguards.
User Control: You can request deletion of your wearable data or revoke consent for data processing at any time.
Our goal is to ensure that your health data remains confidential, secure, and fully within your control.
We may share limited information:
With OTO Health Technologies Inc. for secure processing and app functionality
With healthcare professionals (only when you authorise it)
With third-party service providers (hosting, analytics, communications) under confidentiality agreements
As required by law or for public-health reasons
We never share health data for marketing or advertising purposes.
We retain your data only as long as needed to provide services, meet legal obligations, or conduct legitimate research (in de-identified form). You may request deletion of your data at any time by contacting us.
Depending on your region, you may have the right to:
Access or download your data
