Privacy Policy

Last updated: November 8, 2026

Overview

USB Backup ("the App") is a photo and video backup utility for iOS developed by Oscar Salas ("we", "us"). This privacy policy explains how the App handles your data.

We built USB Backup with privacy as a core principle. Your files are transferred directly from your device to your USB drive. They never pass through any server.

Data We Collect

The App sends usage analytics to the developer, so we can see whether the App works well and where it can be improved. It records:

• When the App is opened, and which screens are shown
• Setup steps: whether photo access was granted, and whether a drive and albums were chosen
• Backups: when one starts and how it ends (finished, stopped or failed), how long it took, and the number and total size of the items copied
• Purchases: when you tap the purchase or restore button and the result (completed, cancelled or failed), with the product and its price
• When the review prompt is shown or the review button is tapped
• Crashes and freezes reported by iOS, with a technical summary of where in the App they happened

Along with this, the App sends information about the device: model, iOS version, App version, language, region setting, time zone, memory, screen size, and display and accessibility settings (such as dark mode or text size).

To tell apart visits from the same installation, the App creates a random identifier that is stored only on your device and is deleted when you delete the App. It is not linked to your name, your Apple ID, or any account, and the App does not use any advertising identifier.

If you choose to send us a message from the App, we receive the text you write and, only if you enter it, your email address so we can reply.

We do not collect your photos or videos, your file names, album names, or backup contents.

Where This Data Goes

This data is sent to our own analytics server (datos.apirest.info), operated by the developer. It is not sold or shared with anyone, and it is not used for advertising or tracking.

As with any network request, our server receives your device's IP address. It is used only to estimate an approximate location (city and country) and is not stored.

If you would rather send nothing at all, turning off the App's network access in iOS Settings stops this data from being sent. The App's backup features work entirely offline and are unaffected.

Photo Library Access

The App requests access to your photo library solely to read your photos and videos for backup purposes. Your media files are:

• Read directly from your device's photo library
• Transferred directly to the USB drive you select
• Never uploaded to any server, cloud service, or third party
• Never analyzed, scanned, or processed for any purpose other than backup

USB Drive Access

The App uses iOS security-scoped bookmarks to access the USB drive folder you select. This access is:

• Granted explicitly by you through the iOS document picker
• Limited to the specific folder you choose
• Used only for writing backup files and reading the backup manifest

Backup Manifest

The App creates a manifest file (photobackup_manifest.json) on your USB drive to track which files have already been backed up. This file:

• Is stored only on your USB drive and optionally cached locally on your device
• Contains file metadata (filenames, dates, sizes) but not the actual photo/video content
• Is never transmitted to any external service

In-App Purchases

The App offers a one-time in-app purchase processed entirely through Apple's App Store. We do not have access to your payment information. Apple's privacy policy governs the purchase transaction.

Third-Party Services

The App does not integrate with any third-party analytics, advertising, or tracking service, and does not use any advertising or tracking identifier. The only external service involved is Apple's StoreKit framework, for processing in-app purchases. Usage analytics go only to our own server, as described above.

Data Storage

All app data (settings, backup history) is stored locally on your device using iOS standard storage mechanisms. This data is:

• Protected by iOS device encryption
• Removed when you delete the App
• Never synced to external services

Children's Privacy

The App does not knowingly collect any information from children under 13. The usage analytics described above are not linked to a name or account and are not used to identify a person of any age.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be posted on this page with an updated revision date.
