Privacy Policy.

The short answer is: your documents never leave your phone. The long answer is below.

What we collect

First name. Stored locally on your device in AsyncStorage. Used for the greeting on the home screen and the "Welcome back" message on the lock screen. Never transmitted to any server.

Documents you scan. Image files and the OCR text extracted from them. Stored locally in your iPhone's app sandbox, encrypted at rest with AES-256-GCM using a key derived from your PIN. Never transmitted to any server. There is no JuanScan server that holds your documents — by architecture, not by policy.

Reminder schedule. If JuanScan reads an expiry date off a scan, it schedules a local iOS notification on your phone. These notifications fire from iOS, not from a push server.

What we do not collect

• No email address.
• No phone number.
• No account.
• No location.
• No contacts.
• No payment information.
• No advertising identifiers.
• No third-party tracking SDKs.

Optional crash and analytics reporting

JuanScan ships with optional integrations for Sentry (crash reports) and PostHog (anonymous product analytics). Both are disabled by default. When enabled in a future build, the data collected is strictly:

• Sentry: stack traces and device metadata (iOS version, app version, device model) when the app crashes. No document data, no user content.
• PostHog: anonymous event names (scan_started, pin_unlock_succeeded, etc.) with no identifiers and no document data.

If we enable either, we will update this policy and Apple's App Privacy declaration before the build ships.

Your rights

Because we store nothing on a server, there is no data to request, export, or delete from our side. Uninstalling the app from your iPhone removes the documents you stored. The "Erase everything" button in the You tab does the same thing without uninstalling.

iCloud Backup

If you have iCloud Backup enabled on your iPhone, Apple may include JuanScan's encrypted document files in your iCloud backup. Those backups are end-to-end encrypted by Apple. JuanScan has no access to your iCloud backup.
