Effective Date: May 1, 2026 · Last Updated: May 11, 2026
CycleBalance ("we," "our," or "us"), operated by Huggler Holdings LLC, a Texas limited liability company, is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use the CycleBalance iOS application (the "App") and our website at cyclebalance.app (the "Website"). We built CycleBalance with a privacy-first philosophy: your health data stays on your device, always.
Your health data never leaves your device. CycleBalance stores all personal health information locally on your iPhone using on-device storage and on-device machine learning (Core ML). There are no servers, no cloud sync, and no third-party analytics tracking your health data.
1. Information We Collect
A. Information Stored On-Device Only (App)
When you use the CycleBalance app, you may enter personal health information such as:
Pregnancy and postpartum data (pregnancy start date, estimated due date, pregnancy outcome)
HealthKit data (with your permission): body mass, sleep analysis, blood glucose, active energy, resting heart rate, and step count
This data is stored exclusively on your device. It is never transmitted to our servers or any third party. We have no ability to access, view, or retrieve this data.
B. Information Collected via the Website (Contact & Support Forms)
If you choose to contact us through one of the forms on our Website (such as the contact form or the support form), we collect:
Your name
Your email address
The subject or topic you select (where applicable)
The content of the message you send us
This information is submitted voluntarily and processed through Formsubmit.co, a third-party form handling service that delivers the message to our support inbox. We use this information solely to respond to your inquiry.
The Website itself does not use cookies, third-party advertising trackers, behavioral analytics, or fingerprinting. We do not set any non-essential cookies, and your visit is not tracked across other websites.
2. How We Use Your Information
On-Device App Data
Your health data is used solely within the app on your device to:
Track and display your cycle patterns, symptoms, and health metrics
Provide personalized insights using on-device machine learning (Core ML)
Generate doctor-ready reports that you choose to export or share
Identify correlations between symptoms, lifestyle, and cycle patterns
All machine learning processing occurs entirely on your device. No data is sent to external servers for analysis.
Website Form Data
We use the information you provide through our contact and support forms solely to:
Respond to your question, feedback, or support request
Diagnose and resolve issues you report (e.g., bug reports)
Improve the App based on user-submitted feedback (in aggregate, never tied back to you for marketing)
We do not use this information for advertising, profiling, or unsolicited marketing.
3. Data Storage and Security
App Data
All health data entered into CycleBalance is stored locally on your device. We leverage iOS built-in security features, including:
iOS Data Protection encryption, which encrypts your data when your device is locked
App sandboxing, which prevents other apps from accessing CycleBalance data
No network transmission of health data — your information never leaves your device
Because your data is stored only on your device, if you delete the app or lose your device, your data cannot be recovered by us. We recommend using your device's built-in backup features if you wish to preserve your data.
Website Form Data
Contact and support submissions are processed by Formsubmit.co and delivered to us via email. We store this information only for as long as needed to handle your request, then archive or delete it. We do not sell, rent, or share it with third parties for marketing purposes.
4. Third-Party Services
CycleBalance is designed to minimize third-party involvement:
Health data: No third-party services have access to your health data for advertising, analytics, or tracking purposes. There are no analytics SDKs, no ad trackers, and no cloud databases connected to your health information.
Apple HealthKit: With your explicit permission, CycleBalance reads health data from Apple HealthKit (body mass, sleep analysis, blood glucose, active energy, resting heart rate, and step count). This data is used solely within the app on your device. CycleBalance does not write data to HealthKit. See Apple's Privacy Policy for details.
Apple and RevenueCat: App Store purchases are handled by Apple. CycleBalance uses RevenueCat to manage subscriptions and in-app purchases by processing purchase receipts and subscription status. Neither Apple nor RevenueCat receives your health logs from CycleBalance for this purpose, and RevenueCat does not have access to your health data. See RevenueCat's Privacy Policy for details.
Website contact & support forms: When you contact us through the Website, we use Formsubmit.co to process the submission. Formsubmit.co receives the information you submit (name, email, subject, and message) and forwards it to our support inbox. Please review Formsubmit.co's privacy policy for details on how they handle submitted data.
Web fonts: Our Website loads the Inter typeface from Google Fonts. Loading the font may cause your browser to send your IP address and user-agent to Google for that single request. This request does not set cookies, but Google may receive that request information under its own privacy practices. See Google's privacy policy for details.
On-device machine learning: CycleBalance uses Apple's Core ML framework to provide insights. All ML processing happens locally on your device. No data is sent to Apple or any other party for this purpose.
5. Data Sharing
We do not sell, trade, or rent your personal information. Because your health data is stored exclusively on your device, we are technically unable to share it.
You may choose to share data from the app (for example, exporting a PDF health report, CSV data export, or JSON backup). Any such sharing is initiated solely by you and is under your control.
We may disclose information submitted through Website contact or support forms if required by law, valid legal process, or governmental request.
6. Your Rights and Choices
App Data
Since all app data resides on your device, you have full control at all times:
Access: All your data is visible to you within the app at any time.
Deletion: You can delete individual entries within the app or delete all data by uninstalling the app.
Portability: You can export your data in multiple formats: CSV exports for spreadsheet use, JSON backups with schema versioning for full data portability, and PDF health reports for sharing with healthcare providers.
Website Form Data
You may request access to, correction of, or deletion of any information you submitted through our Website contact or support forms at any time by contacting us at Contact@cyclebalance.app. We will process your request within 30 days.
7. California Privacy Rights
