Data Privacy and Security

This page is for school and district IT, privacy, and procurement teams who need to understand how Cash Reader handles data before approving it. It is a plain-language summary. For the formal documents, see the links at the end.

Cash Reader is a money identification app for people who are blind or have low vision. The user points the camera at a banknote and the app says the denomination out loud. That is the whole app. It has no social features, no messaging, and no user accounts.

What data the app collects

Cash Reader has no accounts and does not ask users for personally identifiable information. Specifically:

The app does use standard third-party tools for stability and measurement:

These tools collect technical information such as device model, operating system version, app version, and crash logs. They do not receive names, accounts, student records, or the contents of what the camera sees. The full list is under Sub-processors below.

Where data is processed

Banknote recognition runs entirely on the device. After a one-time download of a currency, the app works fully offline. The camera image is processed locally to read the banknote and is not sent anywhere as part of normal use.

Optional, anonymous photo submission

There is one optional way a user can share an image, and it is off by default:

Because this is off unless a user deliberately enables it, a managed or shared device will not submit photos unless someone turns the feature on.

Children and COPPA

Cash Reader is not directed at children and does not knowingly collect personal information from children. Because there are no accounts and no personal input fields, the app does not gather the kind of personal information COPPA is concerned with.

Students and FERPA

Cash Reader creates and stores no student education records. It is a general-purpose assistive tool, much like a magnifier or a screen reader, and it has no access to a school’s student information systems.

Sub-processors

Cash Reader relies on these third-party providers. None of them receive student records or names, because the app holds none.

Data sharing

We do not sell personal data. Aside from the service providers listed under Sub-processors, which process limited device and usage data on our behalf, we do not share data with third parties. On Apple devices, the advertising measurement is subject to the user’s App Tracking Transparency choice. The optional photo submissions are used only to improve recognition and are not shared beyond the storage provider.

Purchases

Cash Reader offers a paid version. All purchases and subscriptions are handled by the Apple App Store and Google Play. The app does not see, process, or store any payment card details. Billing, receipts, and cancellations are managed through the user’s own Apple or Google account.

Retention and deletion

We keep crash and analytics data only for as long as it is useful, in line with the providers’ standard retention, and optional photo submissions only for a reasonable time before deleting them. Because there are no accounts, there is no personal profile to delete. Uninstalling the app stops all collection.

Security model

The app’s design is its main privacy protection. Recognition happens on the device, there are no accounts, and the app stores no student records or personal profiles, so there is no student data store to breach. The limited data the app does send (crash reporting, analytics, advertising measurement, and any optional photos a user submits) is processed and stored by the established providers listed under Sub-processors, under their own security programs.
