Summary: Peadra is a local-first finance app. It works offline. It has no account, no analytics, no ads, and no tracking. Your financial data is stored only on your device in an encrypted local database and is never sent to the developer or any server. Only if you actively send a feedback email does your message (and email address) reach the developer, and it is deleted after handling — see §3.
1. Who we are
Peadra is developed by Arthur Fert (arthurfert.com). Contact: contact@arthurfert.com.
Source code: github.com/Arthurfert/Peadra (GPL-3.0).
2. Data collection - app itself collects nothing
Peadra itself does not collect, transmit, sell, or share any personal or financial data in normal use.
- No personal data is sent to the developer by the app automatically.
- No analytics (Google Analytics, Firebase, etc.).
- No advertising SDKs.
- No account or login on a remote server.
For Google Play Data Safety: No data collected by the app automatically. No data shared with third parties. The only exception is when you choose to send feedback by email (see next section) — that email is processed separately.
3. Feedback via email (optional, mailto: button only)
Peadra has a “Send feedback” button that is just a mailto: link to peadra@arthurfert.com. Tapping it opens your own email app (Gmail, Outlook, etc.) with a pre-filled recipient. The app itself has no mail server, no backend, and sends nothing automatically — nothing happens until you choose to write and hit Send in your email app.
This is entirely optional — the app works fully without it.
- What is sent: Only what you write and your email address as sender, handled by your email provider and mine. No financial data, database content, or device identifiers are attached by the app unless you explicitly paste them.
- Why (purpose): Solely to understand your feedback, fix issues, and improve Peadra, and to reply to you if needed.
- Legal basis (GDPR): Your consent when you voluntarily send the email, and our legitimate interest in improving the app. You can withdraw consent at any time by asking us to delete the conversation.
- Retention: Emails are GDPR-compliant and deleted after your issue / feature request is treated (replied to and, if applicable, noted as an internal task). Not kept longer than necessary.
- Sharing: Never sold or shared. Only read by the developer. Not used for marketing or profiling.
- Your rights (GDPR): You can request access, correction, or deletion of your feedback email at any time by emailing peadra@arthurfert.com. Deletion is done promptly once the request is handled.
- How it works technically: The button uses
mailto:peadra@arthurfert.com. No data goes through a Peadra server; it goes via your email app/provider to our mailbox, like any normal email you send.
You are never required to send feedback to use Peadra. If you prefer not to share your email, you can open an issue on GitHub without revealing your email.
4. Where your data stays
All data you enter - accounts, transactions, categories, currencies - is saved in a local SQLite database on your device. Sensitive fields are encrypted at rest with AES-256-GCM (key derived via PBKDF2). You control it fully:
- Delete anytime: Clearing app data, uninstalling the app, or deleting entries inside the app removes it permanently.
- Import/Export is manual: CSV import/export happens via the system file picker. Files stay on your device unless you choose to share them.
- No cloud backup is performed by the app. If you use OS auto-backup (e.g., Google Backup), that is handled by your OS and its policy.
5. Optional local sync
Peadra can sync between your own devices on the same local network (via mDNS / local discovery and QR pairing). This is opt-in, device-to-device, and does not use an external server. Nothing is sent to the internet during sync.
6. Permissions and why they are used
- Storage / Files (
file_picker): only to let you import/export CSV files when you tap Import/Export. - Camera (
mobile_scanner): only to scan a QR code when you initiate local sync pairing - not used otherwise. - Biometrics (
local_auth): optional app lock - authentication stays on-device via the OS. - Network (
http,mdns_dart,connectivity_plus): only for local-network sync discovery and, if needed, fetching public exchange rates for currency conversion. No financial data is included in those requests.
No permission is used to collect personal data in the background.
7. Currency conversion
If you use multiple currencies, the app may request public exchange rates from a public rate source. The request contains only currency codes (e.g., EUR → USD), not your transactions or identity. If you stay offline or use a single currency, no network request is made.
8. Third-party services
Peadra itself does not embed third-party trackers. As an Android app distributed via Google Play:
- Google Play Services may handle app installation, updates, and crash reporting per Google's Privacy Policy - separate from Peadra.
- No data is shared by Peadra with those services.
9. Children's privacy
Peadra does not target children and does not knowingly collect data from children. Since no data is collected from anyone, no special processing applies.
10. Security
Data is kept locally and encrypted as described above. You should still protect your device with a screen lock and keep backups in a safe place if you export CSV files. In-app access can be protected by the optional PIN / biometric lock.
11. Your rights
For the app itself, no personal data is stored remotely, so you have full control locally: you can view, edit, or delete all data inside the app at any time. For optional feedback emails you sent, you can request deletion at any time (see §3) — it will be deleted promptly after your issue/feature request is treated.
12. Changes to this policy
If the app changes in a way that affects privacy (e.g., adding an optional cloud feature), this policy will be updated and a new “Last updated” date will be shown here and on the Play Store listing.
