1 Introduction & Privacy Commitment
Tech2U Savannah ("we", "us", or "our") develops and operates HerRythm: Period & Cycle Tracker ("HerRythm", "the Application"). We are dedicated to providing a safe, discreet, and reliable cycle tracking experience while vigorously defending your personal privacy.
Menstrual and reproductive health information is among the most sensitive personal data that exists. HerRythm is engineered from the ground up with a privacy-first, offline-first architecture: your health data belongs entirely to you and remains strictly on your device.
2 Complete Health Data Privacy & On-Device Storage
Zero Health Data Cloud Uploads: All period logs, cycle lengths, ovulation calculations, flow intensities, intimate notes, mood entries, and symptom logs are stored strictly inside your device's private local SQLite database and protected preferences. We do NOT operate an external health database or transmit your private health records over the Internet.
The Application processes the following health indicators locally on your device to calculate predictions:
- Cycle History: Start and end dates of past menstrual periods.
- Cycle Parameters: Average cycle length and period duration configured by you.
- Daily Symptoms & Notes: Self-recorded physical symptoms (e.g., cramps, headaches), mood states, and personal notes.
- Predictions: Algorithmic estimates of your next period, fertile window, and estimated ovulation day.
Because these computations execute entirely on-device, our servers never receive, analyze, sell, or share your reproductive health information.
3 Information We Do Not Collect
To ensure maximum transparency, we explicitly declare that HerRythm does NOT collect or access:
- Your name, email address, physical address, or phone number.
- Accounts, social logins, or cloud authentication profiles.
- Your precise GPS location or continuous location history.
- Your contacts, address book, SMS messages, or phone call logs.
- Your device camera, microphone, photos, or media files.
- Biometric identifiers (fingerprints, facial recognition data).
4 Device Permissions & Technical Necessity
HerRythm requests only the bare minimum permissions required for basic operating system functionality and ad-serving compliance:
5 Advertising & Google UMP Consent Framework (GDPR / CCPA)
HerRythm is supported through non-intrusive mobile advertising provided by Google AdMob. To strictly comply with international privacy legislation—including the European Union General Data Protection Regulation (EU GDPR), the United Kingdom Data Protection Act, the Swiss Federal Act on Data Protection (FADP), and the California Consumer Privacy Act (CCPA/CPRA)—we implement Google's certified User Messaging Platform (UMP) SDK.
Google AdMob & Google Mobile Ads SDK
Depending on your jurisdiction and explicit consent choices, Google AdMob may process pseudonymous device identifiers (such as the Google Advertising ID), coarse network location (IP address for country/region identification), and ad interaction telemetry.
Consent Gate: In accordance with EU/UK GDPR regulations, no advertising SDK is initialized, and no ad requests are dispatched until you have received and answered the Google UMP consent dialogue.
For further information on how Google manages advertising data, please review:
Google Advertising Policies &
Google Privacy Policy.
6 User Consent Revocation & Control
We believe user autonomy must be continuous, not a one-time gate. You have the permanent right to withdraw or reconfigure your advertising and privacy consent choices at any time.
On-Demand Consent Revocation: Open HerRythm > tap the Settings tab > select Privacy & Consent Settings. This immediately re-launches the official Google Privacy Options form, allowing you to update your preferences or revoke consent instantly.
7 Data Retention, Portability & Deletion
Because all data is stored locally in your device's isolated app storage sandbox:
- Retention: Your data remains on your device for as long as you keep the application installed.
- Instant Deletion: You can completely and permanently delete all your period logs, symptoms, notes, and preferences at any time by clearing the application data in your Android system settings (Settings > Apps > HerRythm > Clear Storage/Data) or simply by uninstalling the application.
- No Ghost Copies: We maintain no remote backups, shadows, or server-side replicas of your personal information.
8 Children's Privacy Protection (COPPA & GDPR-K)
HerRythm is intended for general audiences tracking fertility, cycles, and menstrual wellness. We do not knowingly collect, solicit, or process personal information from children under the age of 13 (or under 16 in the EEA/UK). If you believe a minor has provided personal data, please contact us immediately, and we will take necessary steps.
9 Policy Updates & Amendments
We may periodically update this Privacy Policy to reflect enhancements in our application or changes in global privacy regulations. When updates occur, the "Effective Date" at the top of this document will be updated. We encourage you to review this policy periodically.
