QR Code Scanner, Maker & Vault

QR Vault is a quiet, well-built home for every QR code you scan or create. It is a QR code scanner, a QR code generator, and a private, biometric-locked vault rolled into one. The app is designed to feel calm rather than busy, and to stay out of your way until you actually need it.
If you have a screenshots folder full of half-cropped QR codes you can never find again, this app is for you.
WHAT YOU CAN DO WITH IT
Scan QR codes and barcodes in a heartbeat. Point your camera and detection is automatic. If a QR lives in a saved photo, pick it from your gallery and the app will read it from the image. After a scan, smart actions appear: open the link, copy the text, write the email, add the calendar event, save the contact, or share it forward.
Generate QR codes for nearly anything. URLs, plain text, Wi-Fi credentials, contact cards (vCard), email, payment links, calendar events, social profiles, app store links, and personal notes. The preview updates as you type, so you always see exactly what people will scan. You can embed a small brand mark in the centre if you like, or leave it clean.
Keep everything in your vault. Saved QRs sit in a tidy library you can search by title or content, filter by type, and pin as favourites. Switch between a soft grid view and a compact list view, depending on how you think. Multi-select to share, lock, or delete several items at once. Export an encrypted JSON backup whenever you want, and import it on a new phone the same way.
PRIVACY THAT TREATS YOU LIKE AN ADULT
We do not show you ads. We do not sell your data, because there is no data to sell. Your vault lives on your device. The app does not require an account, an email address, or a phone number.
Lock the vault behind a 4-digit PIN, your fingerprint, or Face ID. Choose how long the app waits before auto-locking itself again. The PIN is stored only as a hashed value in your device's secure keystore.
DESIGNED TO BE ENJOYED
A warm, considered light theme with cream backgrounds and chocolate accents. An espresso-toned dark theme that is easy on the eyes at night. A built-in text size slider, so every label in the app sits at the size you actually like reading. Subtle haptics on the actions that benefit from them. Works offline. Loads fast.
SMALL, USEFUL THINGS
Paste from clipboard and turn whatever was there into a QR in one tap.
Time-aware greeting on the home screen, so it feels like the app remembers it is morning.
Vault insights: a small chart of recent activity, top QR type, and total scans.
Tip of the day, gentle and dismissable, that surfaces a feature you might not have found yet.

Organising QR codes for a cafe, salon, market stall, or pop-up shop.
