Your Relationship Data, Yours Alone
In a post-Roe world, your menstrual and relationship data privacy matters more than ever. Natural Cycles v2 is built with privacy at its core—per-user encryption, crypto-erase capability, and zero third-party data sharing.
Why Privacy Matters in 2026
The landscape of reproductive health and relationship data privacy has changed dramatically. Here's why we built Natural Cycles v2 differently.
Post-Roe Legal Landscape
Menstrual and relationship data can be subpoenaed in jurisdictions with restricted reproductive rights. Your cycle data deserves legal protection.
Data Broker Economy
Many apps sell user data to advertisers and data brokers. Your relationship insights should never become someone else's commodity.
Targeted Advertising
Personal data enables invasive ad targeting. Your relationship status and health information shouldn't dictate what ads you see.
Global Surveillance
Relationship patterns and health data can reveal deeply personal information. Global privacy protections are increasingly necessary.
Privacy-First Architecture
Every aspect of Natural Cycles v2 is designed with your privacy as the foundation, not an afterthought.
Per-User Encryption
Your birth data, relationship insights, and personal information are encrypted with unique keys that only you control. Not even our engineers can access your raw data.
Crypto-Erase Capability
Complete data deletion ensures your information can be permanently removed when you choose to leave. No backups, no traces, no retained data.
No Third-Party Sharing
We never sell, share, or monetize your personal data. Your relationship insights remain completely private between you and our service.
GDPR Compliant
Built to European privacy standards with full transparency about data processing, your rights, and our obligations under data protection law.
Granular Consent Controls
You control exactly what data is collected and how it's used. Granular permissions put you in charge of your privacy preferences — including the ability to withdraw consent anytime.
Transparency Reports
Regular transparency reports detail government data requests, data breaches, and privacy incidents. We believe in radical transparency.
Technical Privacy Implementation
How we protect your data at every layer of our technology stack.
Data Collection
Minimal data collection by design. We only collect what's necessary for the features you use. Birth data, relationship insights, and usage patterns are encrypted before storage.
Encryption at Rest
All stored data is encrypted using AES-256 with unique per-user keys. Your data remains encrypted in our databases, backups, and logs.
Encryption in Transit
All data transmitted between your device and our servers is encrypted using TLS 1.3. Your information is protected from network interception.
Access Control
Strict access controls limit who can access your data. Role-based permissions, audit logging, and multi-factor authentication protect against unauthorized access.
Data Deletion
When you delete your data, it's cryptographically erased. We don't retain backups or copies. Deletion is immediate and verifiable.

Privacy FAQ
When you delete your account, we initiate crypto-erase deletion of all your data. This process permanently removes your birth information, relationship insights, usage patterns, and any other personal data. Deletion is immediate and verifiable—we do not retain backups or copies of your information.
We only disclose user data in response to valid legal warrants, subpoenas, or court orders. We challenge overbroad or invalid requests and notify users when legally permitted. Our transparency reports detail all government data requests we receive.
Absolutely not. We never sell, share, or monetize your personal data. Your relationship insights, health information, and usage patterns remain completely private. We do not use third-party advertising networks that rely on personal data.
Your data is encrypted using AES-256 with unique per-user encryption keys. This means each user's data is encrypted with a different key, and even our engineers cannot access your raw data. Encryption applies to data at rest (in our databases) and in transit (between your device and our servers).
Under GDPR, you have the right to access your personal data, rectify inaccurate data, erase your data (right to be forgotten), restrict processing, data portability, and object to processing. You can exercise these rights through your account settings or by contacting our privacy team.
We maintain comprehensive security measures to prevent data breaches. In the unlikely event of a breach, we will notify affected users within 72 hours as required by GDPR, provide details of what happened, and outline steps we're taking to prevent future incidents. All breaches are documented in our transparency reports.
