Best QR code scanner apps without ads or tracking (iPhone & Android, 2026)

The best QR scanners without ads or tracking are Binary Eye and QRieux on Android and QR Pro on iPhone, with the Lapnito reader (made by this site's operator) as a simpler fourth option. All four declare that they collect no data in their store privacy sections and none of them sells subscriptions to unlock scanning.

How we picked

A QR scanner has one job, so the differences are almost entirely about what happens around that job. We compared every app on the same points:

• Privacy label. The App Store “App Privacy” section or the Google Play “Data safety” section, read directly from the store page.
• Ads and subscriptions. Whether the listing shows ads, in-app purchases or a paywall around basic scanning.
• Permissions. Camera access is expected; anything beyond camera and optional photo access needs a reason.
• Offline use. Decoding a code never needs a network connection.

This ranking is based on store listings, privacy labels and developer documentation checked in October 2026. We did not run network traces, and privacy labels are declarations by the developers, not independent audits. Ratings and prices change, so check the store page before you install.

Our picks, ranked

1. Binary Eye (Android)

Binary Eye is a barcode and QR reader by developer Markus Fisch. Its Google Play page says “No ads”, lists a long set of supported formats (QR, Aztec, Data Matrix, EAN, UPC, PDF417 and more), can read inverted codes, can generate codes and links to its public source code. The Data safety section declares no data collected and none shared. It is free and its listing shows no in-app purchases.

Pros: open source, ad-free, no data collected per the label, reads unusual formats, also creates codes.
Cons: Android only; the many format and behaviour options go beyond what a casual user needs.

Get it: Google Play

2. QR Pro (iPhone, iPad, Mac)

QR Pro by Crypto Inc. is the strongest iPhone choice we found. The developer describes it as ad-free with no subscriptions and no tracking, and the App Store label reads “Data Not Collected” with no in-app purchases listed. It scans from the camera, from Photos and by drag and drop, previews the content before opening links, creates codes and offers optional iCloud sync. It had a 4.5 average from about 29,000 ratings and was updated on 28 September 2026.

Pros: clean privacy label, link preview before opening, free without a paywall, works across Apple devices.
Cons: Apple platforms only; “no tracking” is the developer's statement, supported by the label but not independently verified; optional iCloud sync stores your library in your iCloud account.

Get it: App Store

3. QRieux (Android)

QRieux is an open-source scanner and creator by Emmanuel Hilson. The listing promises no ads, no tracking and full offline use, and the Data safety section declares no data collected and none shared. It scans from the camera or the gallery, creates codes for links, Wi-Fi and contacts, keeps a history and offers one-tap actions such as joining a Wi-Fi network.

Pros: free, ad-free, no data collected per the label, open source, small and fast.
Cons: Android only; a young project maintained by a single developer, so check the update history yourself.

4. QR Reader & Code Generator / QR Code Scanner – Lapnito (made by this site's operator)

Disclosure: this app is made by lapnito.cz s.r.o., the company behind Best Mobile Apps. On the iPhone the app is called QR Reader & Code Generator. It is free with no in-app purchases, shows the label “Data Not Collected”, scans from the camera or a photo, checks links on the device for phishing patterns and creates codes with export to PNG or SVG. The Android listing, named QR Code Scanner, is simpler: camera and photo scanning plus a local history, with the Data safety section declaring no data collected.

Pros: no ads, no data collected on both platforms, link safety check on iPhone, free.
Cons: very new, with a single rating on the US App Store when we checked, so there is little public track record; the Android version has fewer features than the iPhone one.

Comparison at a glance

• Binary Eye: Android, free, no data collected, open source, creates codes.
• QR Pro: iPhone, iPad and Mac, free, Data Not Collected, link preview, optional iCloud sync.
• QRieux: Android, free, no data collected, open source, history and one-tap actions.
• Lapnito QR apps: iPhone and Android, free, no data collected, on-device link check on iPhone, newest of the four.

Tips for scanning safely

• Look at the decoded link before you open it. A code that points to a lookalike domain or a shortened link deserves a second thought.
• Be wary of codes stuck over other codes in public places, such as parking meters and menus.
• Remember that your phone's built-in camera already reads most QR codes. A dedicated app adds history, creation and batch scanning.
• Grant camera access only. Photo access is needed only if you scan screenshots or saved images.
• In our label check of the most popular free results for “QR scanner” on the US App Store, the six we opened declared data used to track you across apps, and most sold weekly, monthly or yearly subscriptions.

Which one should you pick?

On Android, start with Binary Eye if you want maximum transparency, or QRieux if you prefer a lighter interface. On iPhone, QR Pro is the one to try first. The Lapnito reader is a reasonable free alternative on either platform, but it has the shortest track record of the four. Whatever you choose, a scanner that works offline and asks only for the camera is all you need.

Frequently asked questions

Do QR scanner apps need an internet connection?

No. Decoding happens on the phone. A connection is needed only when you open the link or content inside the code.

Is the built-in camera enough?

For occasional scanning, yes. Both iPhone and most Android cameras read QR codes. A dedicated app helps if you want history, code creation or support for barcode formats.

Why do free QR apps ask for subscriptions?

Many are monetised with ads, trackers or weekly subscriptions rather than by selling the app. The apps above avoid that model according to their listings.

Can a QR code be dangerous?

The code only contains text, usually a link. The risk is the destination, so preview the link before opening it.
