TL;DR — Your Privacy is Guaranteed: Fermento has no backend servers and zero data collection. All data stays on YOUR device. We cannot see, access, collect, or use any of your information—ever.

1. Where Your Data is Saved

When you create timers, track ferments, or log pH readings, here's exactly what happens:

Step 1: All data is automatically saved locally on your device using secure storage

Step 2: Data is backed up automatically every 60 seconds on YOUR device only

Step 3: Your data never leaves your device

Fermento stores the following data locally on your device only:

  • Active Timers: Timer details, start times, current phase, and progress
  • Brew Types: Custom brew configurations you create
  • Fermentation History: Completed brews with phase details and durations
  • pH Readings: Optional pH measurements you record
  • App Preferences: Settings and customizations

We do NOT collect:

  • Personal identifying information (names, emails, phone numbers)
  • Location data
  • Device information
  • Usage analytics
  • Crash reports
  • Any data about your fermentation practices

2. Data Storage

  • Local Storage Only: All data is stored on your device using secure local storage
  • No Backend Infrastructure: We don't operate any servers, databases, cloud storage, or backend systems
  • No Remote Access: We have no technical capability to access, view, or retrieve any data from your device
  • No Data Transmission: Zero data is sent over the internet to us
  • Auto-Backup: Automatic local backups every 60 seconds on your device only

3. Data Sharing

We do NOT:

  • Share your data with third parties
  • Sell your data
  • Use your data for advertising
  • Track your usage or behavior
  • Collect analytics or crash reports
  • Integrate with third-party services

4. Your Rights

You have complete control over your data:

  • Delete All Data: Delete the app to permanently remove all data from your device
  • Export Data: All data can be viewed within the app
  • No Account Required: Since there are no accounts, there's nothing to delete or manage
  • Full Control: You own and control all your data

5. GDPR Compliance

For users in the European Union, Fermento complies with the General Data Protection Regulation (GDPR):

  • Right to Access: All your data is accessible within the app
  • Right to Erasure: Delete all data anytime by deleting the app
  • Right to Data Portability: All data is stored locally and accessible through the app
  • No Processing: We don't process any data because we don't collect any
  • Lawful Basis: No data collection means no processing requiring lawful basis

6. Security

Your data is protected by your device's built-in security features. Since all data stays on your device and is never transmitted to any servers, the security of your data is entirely managed by your device's security (passcode, biometric authentication, etc.).

Why No Backend is More Secure:

  • No servers means no server breaches
  • No databases means no database hacks
  • No data transmission means no interception risk
  • Your data can never leak from our servers because we don't have any

8. Third-Party Services

Fermento does not integrate with any third-party services, analytics platforms, advertising networks, or social media platforms. The app works completely offline and independently.

9. International Users

Fermento is available worldwide. Regardless of where you are located, all data is stored locally on your device. No data is transferred internationally because no data leaves your device.

10. Children's Privacy

Fermento does not knowingly collect information from anyone, including children under 13. Since we don't collect any data at all, COPPA compliance is inherent in our design.
