Logifi is built on one principle: your data belongs on your device, and nowhere else. We operate no servers, no databases, and no analytics. This policy explains exactly what that means.
Nothing. Logifi has no servers. Your income records, expenses, diary entries, documents, vehicle records, and profile are stored exclusively on your own device, in your phone's local storage and encrypted database. We cannot see, access, sell, or share your data — because it never reaches us.
Documents, passwords, diary entries, and identity records you place in the Vault are encrypted with AES-256 (GCM) using a key derived from your PIN via PBKDF2. Your PIN is never stored — only a salted cryptographic hash of it.
If you enable biometric unlock, your PIN is held in your device's hardware-backed secure enclave, managed by Android — it never leaves your phone.
Backups you create are sealed with the same AES-256 encryption before they are written to a file or uploaded, provided you have set a Vault PIN.
Each of these happens only when you choose it, and each is optional:
Google Drive backup (optional). If you tap "Back up to Google Drive", Logifi uploads a single backup file to your own Google Drive account. If you have a Vault PIN set, this file is encrypted with AES-256 before upload — Google only ever stores ciphertext that neither Google nor we can read. You authenticate directly with Google; Logifi never sees your Google password.
Manual export (optional). You can export a backup file to save or share yourself. The same encryption applies.
Avatar generation. The profile avatar is generated by the DiceBear API (dicebear.com). Only your chosen avatar style and a seed word you type are sent — never any personal or financial data.
Receipt scanning engine (first use only). Receipt scanning runs entirely on your device. If the OCR engine is not bundled with your version of the app, it is downloaded once from a content delivery network (jsdelivr.net). Your receipt photos are never uploaded — all scanning happens locally.
Logifi PRO purchases and subscriptions are processed entirely by Google Play Billing. We never see or store your payment details. Google's handling of your payment data is governed by Google's Privacy Policy.
Routine reminders, weekly reports, and vehicle expiry alerts are scheduled locally on your device by the app. No notification data is sent to any server.
Notifications — to deliver the local reminders described above.
Camera / Photos — only when you choose to scan a receipt or attach a document. Images are processed on-device.
Biometrics — only if you enable biometric Vault unlock.
You are in complete control. Deleting a record in the app deletes it from your device. The "Wipe All Data" option in Settings permanently erases everything Logifi has ever stored. Uninstalling the app removes all local data. Backups in your Google Drive are yours to delete at any time from your Drive.
Logifi is not directed at children under 13 and we do not knowingly collect any information from anyone — including children — because we collect no information at all.
Because Logifi processes no personal data on any server, there is no data held by us to access, correct, port, or erase. All rights over your data are exercised directly by you, on your device.
If Logifi's data practices ever change, this policy will be updated and the "Last updated" date revised before the change takes effect.
