Privacy Policy

Last updated: October 2026

Overview

PepStack Pro (“the App”) is designed with your privacy as a core principle. We believe your health data is deeply personal and should remain under your control. This Privacy Policy explains what data we collect, how we use it, and your rights.

Data We Do NOT Collect

PepStack Pro stores all health-related data locally on your device. We do not collect, transmit, or store:

  • Peptide protocols or stacks
  • Injection logs or dosing history
  • Lab results or bloodwork
  • Journal entries or progress photos
  • Apple Health data
  • Personal health information
  • Medical conditions or diagnoses

Data We May Collect

The App does not include its own analytics, advertising, or tracking tools, and we do not receive your usage data. The only non-health data involved is:

  • Account information: Apple ID association for subscription management (handled by Apple; we do not receive your Apple ID)
  • Crash reports: If you turn on “Share With App Developers” in iOS Settings, Apple may share anonymous crash and performance reports with us. You can turn this off at any time in iOS Settings.

Apple Health

With your permission, PepStack Pro can connect to Apple Health:

  • Read: weight, body composition, heart rate, and sleep data, so you can view trends alongside your protocols.
  • Write: progress entries you choose to save to Apple Health.

Apple Health data is processed only on your device. It is never sent to our servers, never used for advertising or marketing, and never sold or shared with third parties. You can change or turn off access at any time in iOS Settings under Health, Data Access & Devices.

Website Analytics

The PepStack Pro website (pepstackpro.com) may use privacy-respecting analytics to understand traffic patterns and improve the user experience. This may include anonymized page views, referral sources, and general geographic data. We do not use invasive tracking cookies or sell data to third parties.

Third-Party Services

The App integrates with the following third-party services:

  • Apple App Store: Subscription billing and management is handled entirely by Apple under their privacy policy.
  • Apple Health: Only with your permission, as described above. Data stays on your device.
  • MyFlowMD: If you choose to connect with a physician through MyFlowMD, you will be directed to their platform, which is governed by their own privacy policy and HIPAA compliance.

Data Security

Because your health data is stored locally on your device, it benefits from your device's built-in security features including encryption, biometric authentication, and passcode protection. We recommend keeping your device software up to date and using a strong passcode.

Data Deletion

Since your data is stored locally, you can delete all app data at any time by deleting the PepStack Pro app from your device. Data the App saved to Apple Health can be deleted in the Health app. To cancel your subscription, manage it through the App Store before deleting the app.

Children's Privacy

PepStack Pro is rated 16+ on the App Store and is not intended for use by individuals under the age of 16. We do not knowingly collect any data from children.

Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date. We encourage you to review this policy periodically.
