Privacy Policy

Last updated: July 26, 2026

SizeFold is a native macOS application that processes images entirely on your own Mac. Your privacy is not a feature we added — it is how the app is built.

The short version

SizeFold does not collect, transmit, store, or share any of your personal information or your images. There is no account, no login, no cloud, no analytics, and no advertising. Your photos never leave your Mac.

What we collect

Nothing. SizeFold does not collect any personal data or usage data.

• We do not have servers that receive your data.
• We do not use analytics, tracking, or telemetry SDKs.
• We do not use advertising or any third-party marketing tools.
• We do not require or offer an account, sign-in, or email registration.

Your images and files

• All image processing happens locally on your device.
• SizeFold only accesses the folders you explicitly choose. macOS App Sandbox restricts it to those user-selected locations, remembered via a standard security-scoped bookmark so you don't have to re-pick the folder each launch.
• Your original images and processed outputs stay on your Mac (or on drives and folders you point the app at). They are never uploaded anywhere.

Network access

SizeFold does not make network requests to transmit your content. The app is built entirely on Apple's native frameworks and includes no third-party runtimes, analytics, or network SDKs.

Purchases

SizeFold is a one-time purchase (a non-consumable in-app purchase to unlock the full app). Payments are processed by Apple through the App Store. We never see or receive your payment details. Purchase and restore are handled by Apple's StoreKit; refer to Apple's Privacy Policy for how Apple handles transactions.

Children's privacy

SizeFold does not collect data from anyone, including children.
