Qkeep: Wallet for Quantus

LUX8 Labs

About this app

Qkeep is a privacy-focused Quantus wallet for QTC. Send privately from Encrypted Accounts, with the zero-knowledge proof built on your phone, and turn on Extra privacy mode so they are checked on your phone instead of asking our server about your address. Your keys stay on your phone, regular transfers are signed on the device with post-quantum ML-DSA signatures, and nothing secret is ever sent to a server.

WHAT YOU CAN DO
- Send and receive QTC, with QR scan to fill in the recipient.
- Keep several 24-word seeds and many accounts in one wallet. Restoring a seed finds the accounts it holds.
- Import a private key and back it up behind your password.
- Make private sends from Encrypted Accounts, with the zero-knowledge proof built on your phone.
- Turn on Extra privacy mode: Encrypted Accounts are checked on your phone from the full public feed instead of asking our server about your address.
- Unlock with your fingerprint or face.
- See the live QTC price and track every transfer until it is final.
- Use Qkeep in English or Simplified Chinese.

SECURITY
- Qkeep is non-custodial: the wallet is encrypted with your password and kept in the app's private storage. Your seed and private keys never leave the phone.
- Biometric unlock uses a key in Android Keystore that works only after a fingerprint or face check.
- Screenshots of the app are blocked, and copies are marked sensitive so Android keeps them out of the clipboard preview.
- Android backups are off: keep your recovery phrase, because uninstalling the app deletes the wallet from the phone.
- The app runs only the wallet code shipped inside it. It talks to the Qkeep relay for balances, history, fees and broadcasting signed transactions; the relay never receives secrets.

Qkeep is also available as a Quantus web wallet at wallet.qkeep.app and as a Chrome extension. Help: wallet.qkeep.app/help. Contact: [e-mail].
