Privacy Policy

Effective date: November 11, 2026
App: QR Pro (Android package com.lennoxdigital.qrpro), by Lennox Digital
Contact: support@lennoxdigitallabs.com

QR Pro is built to work on your device. You don't need an account to use it, and we don't run ads, analytics or tracking.

What stays on your device

These are stored only in the app's storage on your phone. We never receive them:

• Codes you make: their content, design, folders and saved styles.
• Scan history: what you scanned, when, and whether it came from the camera or an image.
• Settings: theme, scanning options and similar preferences.
• Camera and images: the camera feed and any images you pick are decoded on your device to read codes. Frames and images are not saved or uploaded.
• Checks: the link safety check and the scannability score run on your device. Scanned links are not sent to us or to any checking service.

Uninstalling the app removes this data. You can also delete scan history and codes in the app, or export them (Settings > Data) before you delete.

When you open a scanned link, call a number, save a contact or join a network, the app hands that action to your browser or to another app you choose. Those apps have their own privacy policies.

The optional Lennox Digital account

You can sign in to a Lennox Digital account to use Lennox Digital Pro across devices and across our apps. If you sign in, we store:

• your email address and an account ID. With Sign in with Apple you can hide your email, and then we store Apple's relay address;
• how you signed in: email, Google or Apple;
• your purchase history with us: which Pro products the account owns, for example QR Pro or Lennox Digital Pro, with the store, the store's purchase reference and the expiry date.

We don't store your codes, scans or files in the account.

The account and purchase records are stored by Supabase (database and sign-in) on servers in the United States. If you sign in with Google or Apple, they confirm who you are under their own privacy policies and send us your email address and an ID token; we don't get your Google or Apple password.

Purchases

Payments are handled by Google Play (and the App Store on iPhone). We never see your card or bank details. To unlock Pro, the app sends the store's purchase receipt to our server, which checks it with Google Play or Apple and keeps a record: the product, the store's purchase reference, whether it's active, and when it renews or ends. If you're signed in, the record is linked to your Lennox Digital account; if you're not, it isn't linked to any person until you sign in and claim it.

Sharing

We don't sell or share your personal data. The service providers above (Supabase, Google and Apple) process it only to provide sign-in and purchases. We disclose data only if the law requires us to.

Security

All network traffic uses HTTPS. Account data is protected by access rules, so each user can read only their own records.

Deleting your data

• In the app: Settings > Account > Delete account. This deletes the Lennox Digital account and its purchase records in every Lennox Digital app. It doesn't cancel store subscriptions: cancel them in Google Play (Play Store > Profile > Payments & subscriptions) or the App Store. A store purchase still unlocks Pro on the phone that bought it.
• By email: write to support@lennoxdigitallabs.com from the address on the account. We delete it within 30 days.
• Data on your device: delete it in the app (Settings > Data) or uninstall the app.

Children

QR Pro is meant for adults (18 and over) and isn't designed for children. We don't knowingly collect data from children.

Changes

If this policy changes, we'll update this page and the effective date. If we change how the account data is used, we'll say so in the app.
