Privacy Policy
Last updated: November 9, 2025
Introduction
Welcome to Stacco App. We respect your privacy and are committed to protecting your personal data. This privacy policy explains how we handle your information when you use our workout tracking application available on iOS and Android platforms.
Data Collection and Storage
Local Data Storage
Stacco App is designed with privacy at its core. Most of your workout data is stored locally on your device, including:
- Workout logs (reps, sets, exercises)
- Progress tracking data
- Exercise history
- Personal workout preferences and settings
- Custom workout templates and routines
This local storage approach means your workout data remains on your device and is not automatically transmitted to our servers unless you create an account.
Account Creation and Cloud Storage
When you choose to create an account with Stacco App, we store the following information in our secure Supabase database:
- Email address
- Account credentials (securely hashed passwords)
- Workout data you choose to sync across devices
- Account preferences and settings
- Subscription status and history
Creating an account is entirely optional. You can use Stacco App's core features without creating an account, and your data will remain stored locally on your device only.
Third-Party Services
RevenueCat for Subscriptions
Stacco App uses RevenueCat to manage in-app subscriptions. We offer the following subscription options:
- Weekly subscriptions
- Monthly subscriptions
- Yearly subscriptions
When you purchase a subscription, RevenueCat processes the transaction and may collect the following information:
- App user ID (anonymous identifier)
- Subscription status and purchase history
- Device information and platform (iOS or Android)
- Transaction data from Apple App Store or Google Play Store
RevenueCat's privacy practices are governed by their own privacy policy, which you can review at https://www.revenuecat.com/privacy .
Supabase Database
We use Supabase as our backend database provider for storing account information and synced data. Supabase is a secure, open-source platform with enterprise-grade security features. All data stored in Supabase is encrypted in transit and at rest. You can learn more about Supabase's security practices at https://supabase.com/security .
What We Don't Collect
Stacco App does not collect, store, or process:
- Location data or GPS coordinates
- Contact lists or phone numbers
- Photos or media files (except those you explicitly choose to attach to workout logs)
- Biometric data or health information beyond what you manually enter for workouts
- Device identifiers for advertising purposes
- Browsing history or app usage outside of Stacco App

Data Usage
We use the limited data we collect solely for the following purposes:

- Syncing your workout data across your devices (when you have an account)
- Processing and managing your subscriptions
- Communicating with you about your account or subscription
- Improving our app's functionality and user experience

We do not sell, rent, or share your personal information with third parties for marketing purposes. We do not use your data for advertising or analytics beyond what is necessary to operate the service.
Data Security
We implement appropriate technical and organizational security measures to protect your data, including:
- Encryption of data in transit using industry-standard TLS/SSL protocols
- Encryption of data at rest in our Supabase database
- Secure password hashing using bcrypt or similar algorithms
- Regular security updates and patches
- Access controls limiting who can access user data
While we strive to protect your personal information, no method of transmission over the internet or electronic storage is 100% secure. We cannot guarantee absolute security but maintain industry-standard practices to protect your data.
