Who we are

MRZ/NFC Scanner is made by onStart ("we", "us" or "our"). This policy explains what information the app handles, why, who receives it and the choices you have. It applies to the MRZ/NFC Scanner app and this website.

Information we collect

What you create in MRZ/NFC Scanner is stored on your device. It only leaves your device where a row below names a service that receives it.

Here is everything the app collects, why we need it and who receives it:

DataWhat it includesWhy we use itWho receives it
Purchase historyWhat you bought in the app and whenPurchasesGoogle Play Billing
App interactionsScreens you open and features you useAnalyticsGoogle Analytics for Firebase
Crash logsTechnical details when the app crashesCrash reportsFirebase Crashlytics
DiagnosticsPerformance data, device model and system versionCrash reportsFirebase Crashlytics
Device or other IDsIdentifiers such as your advertising ID or an app installation IDAnalytics and crash reportsGoogle Analytics for Firebase, Firebase Crashlytics

We get this information from you, when you enter it or allow a permission, and automatically as you use the app, through the services named above. If you contact us, we also keep your message and email address so we can reply.

Identity documents you scan

Passport and ID card data never leaves your device.

When you scan a document, the app reads its machine readable zone (MRZ) with the camera and, if you choose, its NFC chip. This can include the holder's name, date of birth, nationality, sex, document number, expiry date and the photo stored on the chip.

This data is processed and stored only on your device, in your scan history. It is not sent to us or to any of the services named in this policy, and it is never used for analytics or crash reports. You can delete a record, or all records, from the history at any time.

Files you export to CSV or PDF are saved where you choose and are shared only when you share them yourself.

How we use information

We use information only to:

  • provide the app and its features
  • process purchases and restore them on your devices
  • understand how the app is used so we can improve it
  • find and fix crashes and performance problems
  • answer your questions and support requests
  • keep the app secure and prevent misuse
  • meet our legal obligations

How we share information

We do not sell your personal information, and we never will.

We share information only in these cases:

  • with the service providers listed below, who help us run the app and may use it only for that
  • when the law requires it, such as a valid court order
  • to protect the rights, safety and security of our users and others
  • as part of a merger or sale of the app, under this policy
  • with your consent

Services we use

Google Analytics for FirebaseUnderstand how the app is usedApp interactions and device or other IDsfirebase.google.com
Firebase CrashlyticsFind and fix crashesCrash logs, diagnostics and device or other IDsfirebase.google.com
Google Play BillingProcess purchasesPurchase historypolicies.google.com

Purchases

Payments are processed by Google Play. We never see your full card number. We receive a record of your purchase so we can unlock it and restore it on your other devices.

How long we keep information

  • Crash logs and diagnostics: for up to 90 days.
  • Purchase records: as long as tax and accounting laws require.
  • Messages you send to support: as long as needed to help you.
  • Everything else: only as long as needed for the purposes in this policy.

After that, we delete information or make it anonymous.

Security

Information stored on your device is protected by your device's own security. When information is sent to a service, it is encrypted in transit. No system is completely secure, so we can't guarantee absolute security.

Your choices and rights

  • Ask us for a copy of your personal information, or to correct or delete it, by contacting us by email at hello@onstart.app.
  • Ask us to stop using your information for analytics.

Additional rights by region

Depending on where you live, you may have extra rights. This section covers the European Union and the United Kingdom and the United States.

United States

Residents of California and other states with privacy laws, such as Colorado, Connecticut, Virginia, Utah and Texas, have these rights. In the last 12 months we collected the categories of information in the table above, from the sources and for the purposes described in this policy.

Children's privacy

MRZ/NFC Scanner is meant for adults aged 18 and over, and we don't knowingly collect personal information from children. If you believe a child has given us personal information, contact us and we will delete it.

International transfers

The services we use may process information in countries other than yours, including the United States. Wherever it is processed, we protect it as this policy describes and use legal safeguards where the law requires them.

Changes to this policy

We may update this policy as the app changes. When we do, we update the "Last updated" date above, and we tell you in the app or by other means before significant changes take effect.
