Privacy Policy - QR Code Generator: Logo Maker

Last Updated: November 5, 2026

Overview

QR Code Generator: Logo Maker ("the App") is developed by WittyApps. All QR codes are generated on your device. The App has no account system and no advertising. This policy explains what limited data leaves your device, who receives it and how long it is kept.

Information We Collect

• Amplitude (product analytics). Purpose: to understand which features are used and where people get stuck. Data sent: app interaction events (for example creating, styling, saving, exporting or sharing a QR code, review prompts and purchase results), session start and end, app and operating-system version, device model, language, and an installation identifier generated by the analytics SDK (on iOS, the identifier for vendor). Amplitude also receives and stores the IP address of the connection and uses it to estimate an approximate country, region or city. Not sent: the content encoded in your QR codes, Wi-Fi passwords, contact details, links, locations or logos. These events are not linked to your name or email address. Privacy policy: https://amplitude.com/privacy
• Sentry (crash and error reporting). Purpose: to find and fix crashes and errors. Data sent when an error occurs: error message, stack trace, device model, operating-system and app version, and the IP address of the connection (used to deliver the report, not to identify you). Sentry also receives performance traces for a random sample (about 20%) of monitored operations such as app start: timing data with the same device, operating-system and app version information, used to find and fix slow parts of the App. Privacy policy: https://sentry.io/privacy/ Crash reports contain no QR content.
• Apple App Store / Google Play (payments). Purchases are processed by Apple or Google. We do not receive your card or other payment details.

We do not collect your name, email address, contacts, photos or precise location.

What Never Leaves Your Device

• The content of every QR code you create, including Wi-Fi passwords, contact details, links and locations, is encoded on your device and is never transmitted to us or any server.
• Your saved QR history is stored only in the App's local database on your device.
• Logo images you add are processed and stored only on your device.

How We Use Information

Analytics tell us which features are used; crash reports are used to diagnose and fix bugs. Neither is used for advertising, profiling or marketing, and we do not sell data.

Purchases

The App uses one-time consumable credit packs. Payments are processed by the Apple App Store or Google Play. We do not receive or store your payment details. Credits never expire.

Data Retention and Deletion

• App data (QR history, styles, credit balance): stored on your device until you delete it or uninstall the App. We operate no servers and hold no copy.
• Amplitude analytics events: stored in our Amplitude project for as long as the project is active, without an automatic expiry. When we no longer need the data we delete the project, and we delete the events for your installation within 30 days of a request (see Your Choices).
