Privacy Policy

Last updated: October 2026

Introduction

At ContractDiff, privacy is at the core of everything we do. This Privacy Policy explains how we handle your information when you use our document comparison application.

The short version: We don't collect, store, or transmit your documents or personal data. Everything happens locally on your device.

Information We DON'T Collect

ContractDiff is designed with privacy as the foundation. We explicitly do NOT collect:

• Your documents or contracts
• Content you compare or process
• Personal or business information from your documents
• Usage analytics or telemetry
• Crash reports or diagnostic data
• Your name, email, or contact information
• Device identifiers or location data

How ContractDiff Works

ContractDiff operates entirely on your device:

• Local Processing: All comparison and analysis happens on your Mac. Nothing is sent to external servers.
• No Cloud Upload: Your documents never leave your device. We have no servers to store your files.
• No Internet Required: After installation, ContractDiff works completely offline.
• No Account Required: You don't need to create an account or provide any personal information.

Information We DO Collect

The only information we interact with is:

• Purchase Information: When you upgrade to the Professional version, Apple handles the transaction through the App Store. We receive only a transaction receipt to verify your purchase. We never see your payment details.

Data Storage

ContractDiff stores data only on your device:

• Application Preferences: Settings you configure (UI preferences, default options) are stored locally using macOS standard storage.
• Recent Files List: macOS may store references to recently opened files using secure-scoped bookmarks. These references stay on your device.
• Purchase Status: Your upgrade status is stored locally and verified through Apple's StoreKit framework.
• Comparison History: If you choose to keep a history of comparisons, this is stored locally on your device and can be cleared at any time.

Third-Party Services

ContractDiff uses minimal third-party services:

• Apple App Store: For app distribution and in-app purchases. Apple's privacy policy applies to these transactions.
• Apple StoreKit: For purchase verification. This uses Apple's secure framework and does not share your data with us.

We do NOT use:

• Analytics services (Google Analytics, Mixpanel, etc.)
• Advertising networks
• Social media integrations
• Cloud storage services
• Third-party AI or processing services
• Crash reporting tools

Data Security

Your data security is ensured by:

• Local Processing: Since nothing is transmitted, there's no risk of interception.
• App Sandboxing: ContractDiff runs in Apple's App Sandbox, limiting access to only the files you explicitly open.
• No Network Access: The app does not request or use network permissions (except for App Store purchases).
• Secure File Access: All file operations use macOS secure-scoped bookmarks.
• No Data Retention: We don't store your documents, so there's nothing to secure on our servers.

GDPR Compliance

For users in the European Union:

• We don't process personal data from your documents, so GDPR data processing requirements don't apply to document content.
• You have complete control over your data since everything stays on your device.
• There's no data to export, delete, or rectify because we don't store any.
• No data breach notifications are needed because we don't collect data.
• You can use ContractDiff with confidence for sensitive legal and business documents.

CCPA Compliance

For California residents:

• We do not sell your personal information.
• We do not collect personal information for commercial purposes.
• You have complete control as all processing is local.
• There is no personal information to request, delete, or opt out of.

Children's Privacy

ContractDiff does not collect any information from anyone, including children under 13. The app is rated 4+ and is safe for all ages, though it is designed for professional use.

International Users

ContractDiff can be used worldwide. Since all processing happens locally on your device:

• No data crosses international borders
• No data residency concerns
• Compliant with data protection laws globally
• Suitable for use with confidential legal and business documents in any jurisdiction

Changes to This Policy

We may update this Privacy Policy occasionally to reflect changes in our practices or for legal reasons. Any changes will be posted on this page with an updated "Last updated" date.

Since we don't collect your information, we have no way to notify you directly of changes. We recommend checking this page periodically.

Your Rights

Because ContractDiff doesn't collect your personal data:

• You maintain complete ownership of your documents
• You control all data on your device
• You can delete the app and all its data at any time
• No data remains on our servers (because we don't have any)

Legal Basis for Processing (GDPR)

For EU users, our legal basis for the minimal processing we do:

• Local Preferences: Your consent (by using the app) and legitimate interest (to provide a functional application)
