Personal Information Processing Policy

Article 1 (Purpose of Processing Personal Information)

Pracsol (hereinafter referred to as the "Company") provides the Voice Card application (hereinafter referred to as the "Service"). The Service strictly adheres to the principle of "On-device Data Minimization". We do not collect, transmit, or store any personal sensitive information (voice recordings, text memos) on external servers.

Article 2 (Local-Only Storage & Responsibility)

1. All data created within the App (Voice Recordings, Transcribed Text, Memos, Settings) is stored exclusively in the internal storage and local database (SQLite/Isar) of the user's mobile device.
2. Therefore, if the application is deleted or the device is reset/lost, the data cannot be restored by the Company.

Article 3 (App Access Permissions)

The Service requests the minimum necessary permissions to function:

• Microphone (RECORD_AUDIO): Used solely for capturing voice input to generate memos. The audio stream is processed in real-time buffered memory and saved to local storage. It is never streamed to the internet.
• Storage (READ_EXTERNAL_STORAGE / WRITE_EXTERNAL_STORAGE): Optional. Used strictly when the user explicitly chooses to "Export to CSV" or save a backup file to the device's shared storage.
• Notifications (POST_NOTIFICATIONS): Used to deliver reminders set by the user (e.g., Quick Actions). Notifications are scheduled locally using the device's AlarmManager.

Article 4 (Use of On-device STT Engine)

The App utilizes the device's native Speech-to-Text (STT) engine (e.g., Google Speech Services on Android, SFSpeechRecognizer on iOS).
This process involves passing audio data from the App to the Operating System's internal service. This data flow is governed by the OS provider's privacy policy and is generally processed locally on modern devices for privacy and speed. The App does not intercept or forward this data to any third party other than the OS API.

Article 5 (Destruction of Personal Information)

Since the Company does not hold user data, there is no separate "Destruction Procedure" on our servers. Information is destroyed in the following manners:

• User Deletion: When a user deletes a memo card in the app, the associated audio file and database record are immediately and permanently removed from storage.
• App Uninstallation: Uninstalling the app triggers the OS to wipe the application's private sandbox directory, permanently erasing all Voice Card data.
