Qalkan: QR & Barcode Scanner app, terms of use

The Qalkan apps / QR & Barcode Scanner

Terms of use

Effective 25 September 2026. These terms cover the Qalkan mobile app for iOS and Android.

Acceptance

By downloading and using Qalkan you accept these terms. If you do not accept them, do not use the app.

Licence

We grant you a non-exclusive, non-transferable right to use the app on your devices, for personal or business use. You may not reverse engineer it, redistribute copies of it, or present it as your own product.

Free version and ads

The free version shows ads. Scanning is never limited by a count, a timer or by watching an ad. Ads are not shown on the camera screen, between a scan and its result, at launch, or on sensitive screens. Nothing you scan or create is added to an ad request.

Purchases

Scanned content

The content of scanned codes is not ours and is treated as untrusted. The app never opens a link, joins a network or performs an action by itself; every action follows your tap. Link warnings are informational and are not a security guarantee. You remain responsible for the addresses you open and the networks you join.

Warranty and liability

The app is provided "as is". To the extent permitted by law we do not warrant that it will be uninterrupted or error free, and we are not liable for indirect damages. This does not limit your rights under consumer law.

Intellectual property

The Qalkan name, logo, interface and code are ours. Codes and content you create with the app are yours. QR Code is a registered trademark of DENSO WAVE INCORPORATED.

Changes and termination

If these terms change, the effective date on this page is updated. You can end your use at any time by deleting the app.

Governing law

These terms are governed by the laws of the Republic of Türkiye. Mandatory consumer protections of your country of residence still apply.

Contact

The app is provided by NB Bilişim.
