Privacy Policy

Last Updated: 14 March 2026

Overview

Big3 is committed to protecting your privacy. This policy explains how we handle your information. The core principle of Big3 is that your data belongs to you.

Data Collection & Storage

Local Storage Only: Big3 uses Apple’s SwiftData framework to store your workout logs, 1RM baselines (e.g., Squat, Bench, Deadlift), and profile settings directly on your device.

No Third-Party Servers: We do not host your personal training data on our own servers.

Personal Information: The app may ask for your age, sex, and experience level to calibrate training volumes, but this data remains on your physical device.

Analytics & Diagnostics

We may use Apple’s standard opt-in diagnostic tools to monitor app crashes or performance issues.

We do not track your location or sell your data to advertisers.

Your Rights

Since your data is stored locally, you can delete all information held by the app at any time by simply deleting the app from your device or using the "Reset Profile" feature within the app settings.
