Invoice QR Studio Privacy Policy

Last updated: October 24, 2026

Invoice QR Studio helps you create invoices and QR codes and get paid faster. This Privacy Policy explains what information the app uses and how it is handled.

Information We Use

Invoice QR Studio stores the content you create — your business profile, clients, items, tax rates, invoices, payment records, brand kit (logo, colors, fonts), and the QR codes you design — together with your app preferences and your Pro purchase entitlement status.

This content is created by you. It is kept on your device and, when iCloud Drive is available for the app, synchronized through your private iCloud container. The app does not require an Invoice QR Studio account and does not ask you to sign in to a separate service.

Analytics And Diagnostics

The app uses analytics and crash reporting to understand feature usage, improve the app, and identify technical problems.

Google Firebase may receive an app-instance or installation identifier, general region derived from a masked IP address, app interactions such as screen views and feature events, App Store subscription or purchase product metadata, crash reports, and related device, operating-system, app-version, and diagnostic information.

Invoice contents, client details, QR payloads, payment links, invoice totals, and payment amounts are never included in analytics events. We do not set a Firebase user ID, use IDFA, run advertising networks, use a third-party attribution SDK, or use this data to track you across other companies' apps or websites.

Apple Ads Attribution

Since version 1.1.18, the app asks Apple's AdServices framework once whether this install came from a tap on an Apple Ads ad. Apple answers with its own campaign, ad group and keyword identifiers, the country or region and the date of the tap, and whether the install was a download or a redownload — or says the install did not come from an ad. The app records that answer as analytics events and properties so we can tell which of our ads lead to installs.

This uses no advertising identifier (IDFA), shows no tracking prompt, and is not a third-party attribution SDK. Nothing about you personally is part of the answer.

Scanning Paper Invoices

When you photograph a paper invoice or pick a photo to scan, the page is read on your device and becomes an editable draft. The photo is not uploaded for this.

The optional AI review is different: only if you choose it and confirm on the screen that asks for your consent, the app sends the scanned page images and the draft it read to Google's Gemini API through Firebase AI Logic, which checks the draft and sends the result back to your device. Nothing is sent unless you confirm.

How Information Is Used

We use your business content only to provide the app's features: creating and managing invoices, tracking payment status, designing QR codes, applying your brand, synchronizing your data through iCloud, and unlocking Pro features you purchase.

Anonymous analytics help us understand feature usage and improve the app, while diagnostics help us identify and fix crashes.

Invoice QR Studio does not sell your personal information, and does not use your data to track you across apps or websites owned by other companies.

Storage And Sharing

Your invoices, clients, and designs are stored on your device and may synchronize through the app's private iCloud container according to your Apple Account, iCloud Drive settings, and Apple's terms. Apple provides that storage; the developer does not operate a separate server for your business content.

When you share or export an invoice or QR code, it is sent only where you direct it using the standard iOS share sheet — for example to Messages, Mail, Files, or another app you choose.

A payment QR code encodes the payment link or invoice details that you provide. The app itself does not process payments and does not receive your customers' payment card details.

Purchases

Invoice QR Studio Pro is sold through Apple In-App Purchase. Apple processes the transaction; the app receives only product and entitlement status, not your full payment card details. Firebase may receive purchase event metadata such as product ID, product name, price, and currency for analytics. Subscriptions are managed through your Apple Account settings.

Permissions

If you grant camera access, it is used only to photograph a paper invoice you want to read into the app. Choosing a photo — a logo for your brand kit or an invoice to scan — uses the iOS photo picker, which shares only the photo you pick and needs no photo library permission. If you allow the app to add to your photo library, it only saves the invoice images you ask it to save. If you allow notifications, they are used for reminders about your invoices, such as due dates and the Monday summary of what is still owed. You can change app permissions at any time in iOS Settings. Some features may stop working if a required permission is disabled.

Data Control

You can edit or delete your invoices, clients, items, and QR designs inside the app at any time. Removing the app removes its locally stored data; iCloud data remains subject to your Apple iCloud settings.

Firebase handles previously collected anonymous analytics and diagnostic data under Google's retention and deletion practices. For a privacy or deletion request, email the address below. Because the app has no developer account or Firebase user ID, we may not be able to associate anonymous telemetry with a specific person.

Service Providers

Apple provides iCloud and In-App Purchase services. Google Firebase provides Analytics and Crashlytics services, and — only for the optional AI review you confirm — Firebase AI Logic with Google's Gemini API. These providers process data under their own terms and privacy practices and are required to protect it consistently with this policy and applicable agreements.

This Website

This policy is published on beforego.art. The website uses Vercel Web Analytics and Ahrefs Web Analytics for aggregate visit and referral statistics; those two services do not use cookies. It also uses Google Analytics for Firebase to measure page visits, navigation, button clicks, tool interactions, scroll depth and App Store link views and clicks. Google Analytics uses cookies and browser identifiers to distinguish visits and sessions, and processes technical data such as page paths, referring sites, campaign tags, country, browser and device type. We disable Google signals and advertising personalization. Our website events do not include the text or values you enter into tools, invoice details, checklist contents, email addresses, or arbitrary URL query strings. A click to the App Store records an outbound click, not an installation or purchase. These website statistics are separate from analytics inside the apps. Learn more at How Google uses information from sites that use its services. You can block Google Analytics using your browser settings or the Google Analytics opt-out browser add-on.

Children

Invoice QR Studio is a business productivity app and is not directed to children, and does not knowingly collect personal information from children.

Changes

We may update this Privacy Policy as the app changes. The latest version will be available from the public Privacy Policy URL listed in App Store Connect.
