💸 Deftra

← Back to All Apps

This Privacy Policy describes how Deftra ("we", "us", or "our") handles information when you use our offline-first personal finance and debt management application ("App"). Deftra is designed to keep your financial records under your control.

1. Information We Collect

1.1 Financial and Reminder Data You Create

Deftra stores the following information locally on your device:

• Profiles and ledgers: Account names, balances, categories, tags, and transaction history.
• Debt and receivable records: Installments, due dates, payment status, notes, and follow-up timestamps.
• Reminder settings: Notification preferences, timing selections, and backup preferences.
• Generated exports: JSON, CSV, and PDF files you create for backup, restore, or sharing.

1.2 Data You Explicitly Choose to Import or Select

• Contacts: If you choose the "pick from contacts" option, the app may access a selected contact's name and phone details to help create a debtor or creditor entry.
• Files: If you import a backup or restore file, Deftra processes only the file you select through the system file picker.
• Shared documents: If you export a statement or backup and share it, the file is transferred only through the device share sheet you initiate.

1.3 Limited Online Requests

• Exchange rates: Deftra may request current currency rates from an external service using currency pairs only.
• Advertising: If ads are shown in your build, Google AdMob may collect device identifiers, IP address, and ad interaction data under Google's own privacy terms.

4. Data Storage and Security

• Local storage: Deftra stores ledger and reminder data on your device using local database storage.
• User-controlled backup: When you export data, backup files are created under storage locations you choose, including personal cloud storage accounts such as Google Drive or iCloud if you place the files there.
• No developer-held ledger database: We do not run a central database that stores your transactions, debts, or account balances.
• Manual control: You decide when to export, restore, share, or delete your records.

5. Third-Party Services

frankfurter.app	Live exchange rate lookup	Currency pair requests only
Google AdMob	Advertising	Device identifiers, IP address, ad interaction data
User-selected cloud or sharing providers	Store or send exports you explicitly share	Only the files you choose to move or share

6. Data Sharing

We do not sell, rent, or trade your financial records. Data leaves your device only in the following cases:

• You choose to share or move an exported file.
• You use exchange rate lookup, which sends limited currency request data to the rate provider.
• Your build displays ads through Google AdMob.

7. Your Rights and Choices

• Use without an account: Deftra does not require a central account to manage your records.
• Contacts are optional: You can deny contact access and enter names manually.
• Delete local data: You can clear app data or uninstall the app to remove on-device records.
• Control exported files: You can delete backup, CSV, or PDF files from the storage locations you use.
• Ad personalization: You can manage Google's ad personalization options in your device settings.
