Privacy Friendly QR Scanner

QR Codes become more and more important. In some areas they have even replaced the traditional barcode. A QR Code is able to store up to seven thousand characters and therefore is qualified for more complex content, e.g. vCards. Hence nowadays QR Codes can nowadays be found on nearly every advertisement poster and animate the user to scan it with his smartphone. Thus, it is no longer necessary take a hand written note, it is enough to scan the QR Code. Correspondingly, there are already many QR Code scanner apps available in the Google Play Store. It belongs to the Privacy Friendly Apps group developed by the research group SECUSO at Technische Universität Darmstadt. More information can be found an secuso.org/pfaOur Privacy Friendly QR Scanner App differs with respect to two aspects: 1. The Privacy Friendly QR Scanner App only requires the minimum amount of permissions, namely:• In category "Camera/Microphone": CameraThe camera is used to scan QR Code.• In category "Other": Vibrate and FlashlightThe vibration is used to provide feedback if the scan was successful. The flashlight is used to support the camera in reading the QR Code successfully in bad lighting conditions.Most of the QR Code scanner apps available in the Google Play Store need several permissions on top of the ones needed: e.g. reading contacts or your call log and retrieving data from the Internet. Most of these requirements are not necessary for the functionality they actually are supposed to provide.2. The Privacy Friendly QR Scanner App supports its users in detecting malicious links: QR Codes provide new possibilities for an attacker, as QR Codes can contain malicious links, i.e. links to phishing webpages or webpages from which malware would automatically be downloaded. Therefore it is important to carefully check the link before accessing the corresponding webpage. Since it is difficult for the user to spot malicious links, the Privacy friendly QR Scanner App supports the user by highlighting the domain (e.g. in that case for https://www.secuso.org, secuso.org would be highlighted). To avoid not checking the link and in particular the highlighted domain carefully, the app provides information about possible fraud and its users need to confirm that they checked the link and it is trustworthy. Note, the information shown after scanning an URL based QR Code is not customized for every URL. Hence, it should be considered as an advice for the user how to behave in general.Similar to other available QR Code scanning apps, the Privacy Friendly QR Scanner App supports the following formats:• text• product codes• phone number• sms• email address• email • contact information (e.g. vCards)• URL• WiFi (limited: cannot connect to network automatically)Bar codes are also supported.

Suits my needs perfectly. I love that it does nothing with the scanned content before I have the chance to check it. It gives me the control. Often I just want to scan something like a serial number from a bar code and copy to the clipboard - it can do that too. The only problem is that it has tends to have difficulty focussing the camera and detecting the code. I sometimes need to adjust the position and/or distance, rarely I need a second attempt. But it always gets there in the end.

Wonderful app. Small size, minimum permissions, open source (GPL V3), and it Just Works! At various points in the past I've needed to install a QR-code scanner. As the developer of this app notes, the Play Store is full of various scanner apps of varying degrees of scrupulosity. I think I once installed one that was around 80 MB. 🤔🤨🧐 I imagine many phones these days have a QR-scanner integrated somehow, but it is often lacking. If you need more features then I highly recommend this app!

Being privacy friendly is certainly a great virtue but the app would have been more useful to me if it allowed scanning pictures already present in my gallery. Maybe,being privacy friendly contradicts being able to scan gallery pictures ; then it's understandable.

It scans codes, and lets you save them. But you can't do much with the saved codes. It stores the version, error correction level, and mask, but doesn't display them to the user. You also can't bring up the saved codes full screen for somebody to scan. Generator can't do text QR codes, and crashes if I try to store a generated code.

I like the privacy focus, but the app lacks one core functionality any QR scanner needs: Copying the scanned value without a hassle. Currently, it requires a lot of unnecessary tapping, when the value could just as easily be copied automatically (as a setting to be enabled). This unfortunately makes this app not very comfortable to use.

For some reason beep signal setting is not working (can't turn off the signal). Still, application is awesome. It just does what it meant to do without useless features and ads. Best option on whole play market for sure!

What a relief! I went through ten other scanner apps, but all of them had turned treacherous. This one works simply and well; and there can be no higher praise for a piece of software.

Great app. No ads, no data transfer. Only thing missing for me is the feature to enlarge the scanned qr code. It's possible to scan in the history, but fullscreen on click would be great

Thanks so much for providing an easy to use, privacy friendly, and ad free app for free. Please fix the beep on scan though. It is off in the settings, but still beeps quite loudly.

Used to work, but now crashes as soon as it sees a QR. Maybe it has anxiety... 🤔😅

And. B. Jan 23, 2022     

Great app, zero tracking. Fantastic. And it is open source code.

Ste. C. Mar 27, 2019     

Possibly the best QR scanner ever. Not because of what it does but because of what it doesnt do. Not spyware. not adware. not exposing you needlessly.

Rob. B. Jan 30, 2022     

Finally, an app to replace ZXing without invading the tiny remaining sliver of my online privacy. Thank you!

Gio. L. Dec 30, 2019     

Very simple interface.no ads at all.problem is that after scanning qr and showing url app and clicking proceed it's stucks one place, so you must close app and reopen for another code.

Can't scan saved images. Useless. No dark theme. Can't just copy the recognized text to the buffer.

A. G. u. Sep 16, 2018     

Sorry, app is jolly good, but unfortunately upon installation it makes another app crash: Mobile Manager, scanning "Privacy & Security". Same for other apps of this Author. Asus Zenfone 2, Android 5.0. Thank You anyway for Your commitment and best regards.

An app that does what it needs to -- scans QR codes. Love that it only uses the camera and doesn't request access to everything in order to sell my life information to marketers. Wish more developers took this approach!

Cic. M. Aug 2, 2019     

Cool,but there are problems. If you generate a qr code why can't you read it from a picture inside the device? also, why no zoom and where are the generated codes stored?

Hao. Mar 10, 2021     

It's simple to use. Just wish it had zoom in/out features to scan.

Myl. Jul 17, 2020     

This app is fantastic. Minumal permissions are required and it warns you about dangerous sites before opening. I cannot reccomend it enough!

Jan. T. May 27, 2020     

Great app without useless features or ads... But please fix the beep on scan (disable doesn't work). Thx!

Jes. L. Jan 11, 2019     

Does what it says on the tin. Doesn't require the keys to your life to operate. Just camera access, as it should be. Thanks!

didn't work on pixel 2xl. has permissions granted, but won't scan a barcode.

Kim. C. Sep 24, 2021     

Slow to focus. Couldn't find Barcode item online. Said "no search app". Qr code uses duckduckgo not the default on phone.

Ste. L. Jun 24, 2019     

good idea but it does nothing. pity. Galaxy A8 2018 andoid 9. i click proceed>search on web and it opens the photo gallery.

Best QR Code reader out there. Privacy oriented, great features and very lightweight

jp. Aug 9, 2019     

Can't hit back after scanning. Everything just freezes. Did anyone test the update?

sam. s. Nov 13, 2019

T. Dec 6, 2020     

Perfect! Other apps require invasive permissions, this one does not.

Jem. Z. Oct 30, 2020     

I can scan and generate URIs now, without granting unnecessary permissions. (v3.1.0)
