Privacy Policy

Last Updated: January 2, 2026

Overview

Axis is a mobile application designed to help users track and visualize their testosterone replacement therapy (TRT) data. This Privacy Policy explains how we handle your information.

Data Collection

We do not collect any personal data.

Axis is designed with privacy as a core principle. All data you enter into the App—including injection logs, symptom tracking, lab results, and protocol settings—is stored exclusively on your device.

What We Don't Do

• We do not collect personal information
• We do not transmit your health data to external servers
• We do not use behavioral analytics or advertising trackers
• We do not share data with third parties
• We do not create user accounts or profiles on our servers
• We do not use cookies or similar tracking technologies

Local Storage Only

All information you enter in Axis is stored locally on your device using SQLite database technology. This includes:

• Injection history (dates, doses, compounds)
• Symptom logs (mood, energy, libido, etc.)
• Lab results (testosterone levels, bloodwork)
• Protocol configurations
• App preferences and settings

Crash Reporting

We collect anonymized crash logs and error reports to improve app stability. These reports contain no personal health data—only technical information about what went wrong:

• Device type and OS version
• App version
• Stack traces and error messages
• General performance metrics

This diagnostic data cannot be linked to your identity or your therapy data. Crash reports are processed by Sentry, a third-party error monitoring service, solely for the purpose of identifying and fixing bugs.

Data Export

You can export your data at any time in CSV format through the Settings menu. This allows you to keep backups, share data with your healthcare provider, or transfer data to other applications.

Data Deletion

Since all data is stored locally on your device:

• Uninstalling the App will delete all your data
• You can reset the App through Settings to clear all data
• We cannot recover deleted data as we never had access to it

Third-Party Services

Axis does not integrate with any advertising or behavioral tracking services. We use Sentry for anonymous crash reporting only (see above). The App operates primarily offline and does not require an internet connection for core functionality.

Children's Privacy

Axis is not intended for use by individuals under 18 years of age. We do not knowingly collect information from children.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected in the "Last Updated" date at the top of this document.
