Problem.
Most QR code scanners are bloatware. They harvest your data or charge you $10/month for basic QR code scanning and generation. I built QrOvio because I wanted a professional QR code reader and barcode scanner that respects the user.

Everything is free. No locked features. If you find it useful, help me pay for the developer license.
BUY ME A COFFEEFrequently Asked Questions About QrOvio
Is my data really safe with this QR code scanner?
Yes. QrOvio never connects to a server. Your QR code scan history and generated codes stay in your device's local sandbox. If you delete the app, your data is gone forever. Complete privacy guaranteed.
Will you add ads to this free QR scanner later?
Never. The app's core philosophy is speed and cleanliness. Ads break that experience. QrOvio will always be free with no advertisements. Support comes only through voluntary donations.
Does QrOvio work offline?
Yes, 100%. The app works completely offline. Scanning and generating QR codes requires zero internet connection. The Wall feature requires internet only for viewing community messages.
What types of QR codes can I scan?
QrOvio scans all standard QR codes and most barcodes including URLs, text, WiFi credentials, contact information (vCard), emails, phone numbers, SMS, locations, and more. It also supports EAN, UPC, and other barcode formats.
Can I create QR codes with custom colors or logos?
The mobile app generates standard black-and-white QR codes for maximum compatibility and reliability. Our web generator offers color customization and will soon support logo embedding for professional use.
Is there a limit to how many QR codes I can scan or generate?
No limits. Scan and generate unlimited QR codes. Your scan history is stored locally on your device with no cloud syncing, so storage is only limited by your device capacity.
How does The Wall moderation work?
All submissions to The Wall are manually reviewed before being published. Messages containing hate speech, spam, explicit content, or harmful material are rejected. We aim to keep it fun, creative, and safe for everyone.
Which platforms is QrOvio available on?
QrOvio is currently available on iOS (App Store) with Android (Google Play) in public beta. Both versions offer identical features and the same privacy-first experience.
Can I export my scan history?
Yes. You can export your entire scan history as a CSV file from the app settings. This includes timestamps, QR code content, and types. Your data belongs to you.
How can I support the development of QrOvio?
The best way is through Buy Me a Coffee donations. Every contribution helps cover developer licenses, hosting, and future development. You can also leave an App Store review or share the app with friends who value privacy.
