Offline-first · Encrypted on-device

Documents, bills, passwords & funds — locked to your device, not someone's server

Tuckbox keeps everything you'd otherwise track across a dozen apps — documents, bills, purchase orders, warranties, loans, mutual funds, to-dos, important dates, passwords, credit cards, bank accounts, folders, and notes — in one encrypted vault on your phone.

What it does

13 modules, one encrypted vault

Everything below lives in the same on-device database — no separate app, login, or sync required per module.

Documents

IDs, contracts, warranties, and any file — organized and searchable.

Bills

What's due, when, and to whom — with due-date reminders.

Purchase Orders

Vendors, amounts, and status — from draft to delivered.

Warranty

Purchase records with expiry tracking, so coverage doesn't quietly lapse.

Loans

Loan amounts, remaining balances, and terms, in one place.

Mutual Funds

Funds, invested amount, and current value, tracked over time.

To-Do

Simple tasks, standalone or linked to any other record.

Important Dates

Birthdays, anniversaries, renewals — reminders for what matters.

Folders

Photos, audio, and files, organized your way.

Password Vault

Logins saved and encrypted, right alongside everything else.

Credit Cards

Card details and running balance, tracked at a glance.

Bank Accounts

Balances across every account, always current.

Notes

Quick notes, encrypted like everything else in your vault.

Scan to auto-fill

Photograph a bill or card and Tuckbox pre-fills the fields — recognition runs entirely on your device.

App lock

PIN or biometric lock, plus a screenshot guard for sensitive screens.

How it works

Set up in under a minute

No sign-up form, no email verification, no waiting on a server.

1

Install & add your name

That's the entire setup. No email, no password, no account creation.

2

Start adding records

Documents, bills, passwords, funds, and more — scan a photo to auto-fill fields, or enter them by hand.

3

Back up, if you want to

Connect your own Google Drive anytime from Settings. Off by default, on your terms.

Under the hood

Encrypted where it's stored, not just in transit

Every record lives in a SQLCipher-encrypted database on your device. The encryption key never leaves your device's secure storage (Android Keystore / iOS Keychain) — if that key can't be read, the app locks rather than quietly falling back to unencrypted storage.

  • ✓
    On-device database. Every module — documents, bills, passwords, funds, and more — never leaves your phone unless you turn on backup.
  • ✓
    Fail-closed encryption. No key, no data access — the app locks itself rather than degrade security.
  • ✓
    On-device scanning. Document/card recognition runs locally; no photo or extracted text is ever sent to a server.
  • ✓
    No account to use it. Onboarding just asks for a name — the app works fully offline from the first launch. A Google account is only ever requested later, on demand, if you turn on Drive backup.

Back up to your Drive — never to ours

Tuckbox has no backend database of its own. If you turn on backup, your encrypted data is uploaded to your own Google Drive using the narrowest access scope Google offers (drive.file) — Tuckbox can only ever see the files it created, never the rest of your Drive. Restore or delete a backup at any time from Settings.

FAQ

Common questions

Do I need an account to use Tuckbox? +

No. Setup only asks for a display name, and the app works fully offline from the very first launch.

Does Tuckbox work without an internet connection? +

Yes, entirely. Internet access is only ever used for optional Google Drive backup/restore — nothing else in the app needs it.

What happens if I lose my phone? +

If you'd enabled Google Drive backup, restore it on a new device using the same Google account. If backup was off, your data was local-only and can't be recovered remotely — that's why we recommend turning it on if losing the device would matter to you.

Can Tuckbox see my documents if I turn on backup? +

No. Backup uses Google Drive's most restrictive access scope (drive.file), which only lets the app see files it created itself, and your data is encrypted before it's ever uploaded.

Does the receipt/card scanning feature send my photos anywhere? +

No. Scanning runs fully on-device using Google ML Kit — no image or recognized text ever leaves your phone.
