Paylert Privacy Policy

Last Updated: January 25, 2026

This Privacy Policy describes the policies of James Stradella ("we", "us", or "our") regarding the collection, use, and disclosure of user information ("you" or "your") in connection with the use of the Paylert mobile application (the "App").

Paylert is built on the principles of "Privacy-by-Design" and "Data Minimization". Our core mission is to ensure your financial data remains under your exclusive control at all times.

1. Data Controller

In accordance with the General Data Protection Regulation (GDPR - EU 2016/679), the Data Controller is: James Stradella – Contact Email: jstradella@gmail.com

2. Data Types and Processing Methods

2.1 Local Storage (Default) All data entered (amounts, deadlines, categories) or extracted via OCR is stored exclusively on your device's local memory. We do not transfer, store, or maintain copies of your financial data on our own servers.

2.2 Cloud Backup (Google Drive API) - PRO Feature If you choose to enable the Backup function, the App requests access to your Google Drive account using the drive.file scope.

• Purpose: To create and read a backup file for data restoration purposes across devices.

• Access Limitation: The App can only access files that it has created itself. We have no access to your other personal files or folders on Google Drive.

• Encryption: All backup files are locally encrypted on your device using AES (Advanced Encryption Standard) before being uploaded. This ensures that the backup content is only readable through the Paylert App and remains completely inaccessible to third parties, including both us and Google.

2.3 Calendar Integration (Google Calendar API) - PRO Feature The App requests permission to interact with Google Calendar to add your deadlines as events.

• Purpose: To help you plan your finances by visualizing deadlines within your primary calendar.

• Access Limitation: The App only writes events related to the deadlines you specifically confirm. It does not read, modify, or collect information from any other existing events in your calendar.

2.4 OCR and Image Processing Processing of images (photos of bills or PDFs) for data extraction is performed entirely on-device. No images or documents are transmitted to external servers for analysis or storage.

3. Payment and License Management

Paylert uses RevenueCat to manage PRO licenses and in-app purchases made via the Google Play Store.

• Processed Data: RevenueCat receives an anonymous transaction identifier to validate your subscription status.

• Financial Data: James Stradella and Paylert do not have access to your credit card or payment method details, which are handled exclusively by Google.

4. Third-Party Services

The App utilizes necessary technical libraries for its core operations:

• Google Play Services: For app distribution and system notifications.

• RevenueCat: For PRO license validation.

• Google Cloud Console (APIs): For user-requested Drive and Calendar integrations.

5. User Rights (GDPR)

As a user, you have the following rights:

• Deletion: You can delete all your data by uninstalling the App or manually removing the encrypted backup file from your Google Drive.

• Portability: You can export your data at any time using the backup file generated by the App.

• Revocation of Consent: You can revoke Paylert’s access to Google Drive or Google Calendar at any time through your Google Account Security settings ("Third-party apps with account access").

6. Security

Paylert does not maintain a central database. The security of your data depends on your device's security (PIN, Biometrics) and your Google Account security for cloud backups. The App adds an additional layer of protection via local end-to-end encryption for all cloud-stored files.
