QuickCards privacy policy

Effective 28 October 2026

Who we are

QuickCards (package com.quickcards.app) is a local-first card organizer published by Surety. Privacy contact: support@surety.money.

What the app stores

You can enter card details (card number, expiry, CVV, name on card), plus a bank, card type, network, tags, a note and an optional payment due day. Holder, bank, card type, network and tag names are stored too.

All of it stays in the app's private storage on your device. Card number, expiry, CVV, holder name, note, archive reason and the bank name stored on each card are encrypted with a key held by the Android Keystore. Bank, card type, network, tag and card-variant names are plain labels because they are not card data. There is no QuickCards account, no QuickCards server, no analytics, no advertising and no crash-reporting SDK.

What the app does not do

QuickCards does not request the INTERNET permission and does not transmit your data to us or to anyone else. We cannot see your cards. We do not collect, sell or share your data.

When you choose to send data somewhere

• Share: the Android share sheet sends the card text you confirm to the app you pick.
• Autofill: when you tap a QuickCards suggestion in another app's payment form, QuickCards fills the fields you selected. It reads that form's field labels only to fill it and does not save or transmit the form.
• Export backup: you choose a file location. The backup is encrypted with the password you enter. Where the file goes, including a cloud provider you pick, is your choice.
• Clipboard: copying a card value places it on the Android clipboard for the time you chose, then QuickCards clears it. On Android 13 and later the clip is marked sensitive.
• Notifications: if you turn on "Show expiry and CVV after copying", the copy notification is silent and private on the lock screen. It is off by default. Reminders show only the bank and the last four digits.

Permissions and why

• Biometric or device credential: unlock the app and sensitive actions.
• Notifications: reminders and the optional copy notification.
• NFC: read a contactless card's number and expiry while the "Tap your card" sheet is open. The CVV is never on the chip. This is optional and hidden on phones without NFC.
• Boot completed and time changes: re-arm the local reminder alarm.
• Hide overlay windows: protect the app from tapjacking overlays.

Retention and deletion

Data stays on your device until you delete it. Settings › Backup › Erase all data permanently deletes cards, holders, banks, types and tags, and resets networks to the built-in defaults. Uninstalling the app removes its private storage. A backup you exported is outside the app and must be deleted by you.

Children

QuickCards is a personal organizer for adults and is not directed to children.

Changes

If this policy changes, the new version is published at this URL and in the app with a new effective date.
