Effective Date: January 23, 2026

Welcome to Z3 Solutions. This Privacy Policy explains how we collect, use, store, protect, and share your information when you use any of our applications. This policy consists of two parts: General Privacy Practices that apply to all Z3 Solutions applications, and App-Specific Policies that detail unique data handling for each application.

By using any Z3 Solutions application, you agree to the terms outlined in this Privacy Policy.

Part 1: General Privacy Practices

The following practices apply to all Z3 Solutions applications unless otherwise specified in an app-specific section.

1.1 About Z3 Solutions

Z3 Solutions is an independent software development company creating mobile and web applications for personal health tracking, wellness management, and productivity. Our applications are privately developed and are not affiliated with any healthcare providers, medical institutions, or insurance companies unless explicitly stated.

1.2 Information We Collect

Information You Provide: This includes data you voluntarily enter into our applications, such as profile information, settings, preferences, and any content you create within the apps.

Automatically Collected Information: We may collect device information (device type, operating system version), anonymized usage data, and crash/performance data to improve app functionality.

Contact Information: If you contact us for support, we collect your email address and any information included in your message.

1.3 How We Use Your Information

We use collected information solely to provide and improve the functionality of our applications, including: storing and syncing your data, delivering notifications and reminders, responding to support inquiries, and analyzing anonymized usage data to enhance user experience.

We do not sell your personal information. We do not use your data for advertising, marketing, or any purpose unrelated to our apps’ core functionality.

1.4 How We Share Your Information

We do not sell, rent, or disclose your personal information to third parties, except in the following limited circumstances:

Service Providers: We use third-party services (such as cloud storage providers) that process data on our behalf. These providers are contractually obligated to protect your data.

Legal Obligations: We may disclose data if required by law, such as in response to a court order or legal process.

User-Initiated Sharing: Some apps allow you to share data with others (e.g., via sharing codes). You are responsible for sharing only with trusted individuals.

1.5 Data Storage and Security

We implement industry-standard security measures to protect your data, including encryption in transit (HTTPS/TLS) and at rest, secure authentication protocols, and access controls limiting data access to authorized personnel only.

While we strive to protect your data, no system is completely secure. We cannot guarantee absolute security against unauthorized access, data breaches, or data loss.

1.6 Your Data Rights

Depending on your location, you may have certain rights under applicable laws (e.g., GDPR, CCPA), including:

Access: Request a copy of the data we hold about you.

Correction: Request correction of inaccurate data.

Deletion: Request deletion of your data from our systems.

Portability: Request a transferable copy of your data.

To exercise these rights, contact us at zack@zthreesolutions.com. We will respond within the timeframes required by applicable law.

1.7 Children’s Privacy

Our applications are not intended for use by children under 13 without parental consent, in compliance with COPPA and similar laws. If you believe a child under 13 has provided data without parental consent, contact us and we will promptly delete the data.

1.8 International Data Transfers

Our services may use servers located outside your country. If you are in the EEA, UK, or other regions with strict data protection laws, your data may be transferred to countries with different privacy standards. We rely on appropriate safeguards to ensure lawful data transfers.

1.9 Data Retention

We retain your data only as long as necessary to provide our services or comply with legal obligations. Inactive accounts may have data deleted after 12 months of inactivity. Upon deletion request, we will remove your data within 30 days unless legally required to retain it.

1.10 Changes to This Policy

We may update this Privacy Policy to reflect changes in our practices or legal requirements. We will notify you of significant changes via our website or in-app notifications. Continued use of our applications after changes indicates acceptance of the updated terms.

Part 2: App-Specific Privacy Policies

The following sections detail specific data handling practices for each Z3 Solutions application. These supplement the General Privacy Practices above.

2.1 Proteus — Personal Health Optimization App

About Proteus

Proteus is a personal health optimization app that aggregates data from multiple sources to give users a unified view of their health metrics. Proteus helps users track sleep quality, monitor cardiovascular training, aggregate exercise data, and correlate lifestyle interventions with health outcomes.

Third-Party Health Data Integrations

Proteus integrates with third-party health platforms to import your health data. Currently supported integrations include:

Garmin Connect: Sleep stages, heart rate, heart rate variability (HRV), activity/exercise data, steps, and stress metrics.

Apple Health: Activity, sleep, heart rate, and other health metrics available through HealthKit.

CGM Devices: Continuous glucose monitoring data from compatible devices and platforms.

How We Handle Third-Party Health Data

Read-Only Access: Proteus only reads data from connected platforms. We do not write, modify, or delete data on third-party platforms.

User-Initiated Connection: You must explicitly authorize each integration. You can disconnect any integration at any time through the app settings.

Data Storage: Health data imported from third-party platforms is stored on-device or in your private cloud storage (depending on your settings). Data is encrypted at rest and in transit.

No Third-Party Sharing: We do not sell, share, or transfer your health data to any third parties for marketing, advertising, research, or any other purpose.

Data Minimization: We only import the specific data categories necessary for Proteus functionality. We do not access or store data beyond what is needed for the features you use.

Your Control Over Health Data

You maintain full control over your health data in Proteus:

Connect/Disconnect: Connect or disconnect third-party integrations at any time.

Delete Data: Delete all imported health data from within the app.

Export Data: Export your data in standard formats.

Account Deletion: Request complete account and data deletion by contacting us.

Additional Data Collected by Proteus

In addition to imported health data, Proteus may collect:

User-Entered Data: Supplements, medications, lifestyle interventions, notes, and goals you manually enter.

App Usage Data: Anonymized analytics to improve app performance.

Device Information: Device type and OS version for compatibility purposes.

2.2 Tolerance Tracker & Tolerance Tracker 2 — Allergy Treatment Tracking Apps

About Tolerance Tracker

Tolerance Tracker and Tolerance Tracker 2 are mobile applications designed to help users manage and track daily intake of items related to structured allergy treatment plans. These apps are independently developed and are not affiliated with the Food Allergy Institute or any healthcare provider.

Data Collected

User-Provided Data: Cycle details, item details (medicine, maintenance food, treatment food, recommended food), daily intake logs, room codes, user preferences, and photo documentation.

Automatically Collected Data: Device information, anonymized usage data, and crash reports.

Important: We strongly recommend using nicknames or initials instead of full names and avoiding entry of sensitive health information.

No Health Framework Data Collection

Tolerance Tracker does not collect or process health data as defined by Apple’s HealthKit, Google Health Connect, or HIPAA. All data entered is treated as general user input. The developer is not a covered entity under HIPAA, and these apps are not intended to serve as medical records.

Data Storage

Data is stored in Google Firebase, encrypted in transit and at rest. Data syncs in real time for shared rooms. Inactive cycle data may be deleted after 12 months.

Room Code Sharing

When you share a room code, other users gain access to the associated cycle plan and logs. Share room codes only with trusted individuals. You are responsible for managing access.
