Privacy Policy

Last Updated: May 25, 2026 (v1.0)

1. Overview

PDF Compressor (Bundle ID: com.MASIYA.pdfcompressor, hereinafter "the App") is developed by an independent developer ("we", "us"). We take your privacy seriously. This policy explains how we handle your data.

Key point: The App does not collect, transmit, or store any personal information on our servers. All data is stored locally on your device only.

This policy is effective as of April 1, 2026. By downloading, installing, or using the App, you acknowledge that you have read and agree to this Privacy Policy in its entirety. This policy is available at any time via the App Store listing and this page.

2. Information We Collect

The App does not collect:

  • Name, phone number, email address, or other identifying information
  • Location data
  • Device identifiers (IDFA, IDFV, etc.)
  • Usage analytics or crash reports

Data processed and stored locally on your device only (we cannot access this):

  • The PDF file you actively select, used temporarily during the analysis and compression process — the original file is not retained after processing
  • Generated PDFs written to the system temporary directory (cleaned up by the system or the App when you select a new file or exit the App)
  • Daily free compression counter and next reset time
  • Pro purchase entitlement state (Lifetime Pro, one-time purchase)
  • Recent compression presets, quality modes, and app preferences

3. In-App Purchases

The App offers a one-time in-app purchase to unlock Lifetime Pro (unlocked unlimited compressions, custom target sizes, and high-quality modes). Generous free daily compressions are included. All purchases, refunds, and restores are processed through Apple's App Store payment system (StoreKit 2). We do not access, collect, or store any of your payment information (credit card numbers, bank accounts, Apple ID passwords, etc.). Pro entitlement state is determined solely from the local transaction receipts returned by Apple and never communicates with a developer server.

4. Photos and Files Access

The App uses Apple's system PhotosPicker and UIDocumentPicker to let you select PDF files or photos. You only authorize access to the specific file or image you actively pick. The App does not request full photo library or full file storage access, and never scans or reads other unauthorized files. The selected file is used only on device for analysis and compression — no copy of the original file is retained after processing.

5. File Saving and Sharing

The generated PDF file can leave the App in the following ways:

  • "Save to Files": writes to your on-device iCloud Drive, local folders, or other storage locations
  • System share sheet: iOS passes the compressed PDF file directly to a destination app you choose (Messages, Mail, WeChat, etc.)

All writing and sharing above is handled directly by iOS and never passes through a developer server. The App does not upload, back up, or sync your document contents.

6. Information Sharing

We do not sell, transfer, or share any personal information with third parties. The App contains no third-party advertising SDKs or analytics SDKs.

7. Data Security

Your data security relies on iOS sandbox mechanisms and device encryption. The selected PDF file is only read temporarily during the compression process, and the generated PDF is saved in the system temporary directory and released when you select a new file or exit the App. To permanently delete all local data, simply delete the App from your device — this clears the daily free counter, the cached Pro entitlement, and your app preferences.

In the event of a security incident that may affect user data, we will notify you within a reasonable time through app updates or on this page.

8. Minors' Protection

The App is a general-purpose PDF size compression tool suitable for users of all ages. Since the App does not collect any personal information and does not include any social posting, user content distribution, or online community features, there is no scenario in which a minor's personal data could be collected or processed. If the App is used to process documents containing minors' sensitive information, this should be done by a guardian, and the processed files should be kept private and submitted only to trusted platforms.

9. Your Rights

Under applicable privacy laws (including China's Personal Information Protection Law), you have the right to access, copy, correct, and delete your personal information. Since we collect no personal information, no data access or deletion request to us is needed. To delete all locally stored data, simply delete the App from your device.

10. Changes to This Policy

If we make significant changes, we will notify you through app update notes or a prominent notice on this page. Your continued use of the App after changes take effect constitutes acceptance of the updated policy. If you do not agree with the changes, you should stop using the App.

12. Governing Law

This Privacy Policy is governed by the laws of the People's Republic of China, including the Personal Information Protection Law (PIPL), the Cybersecurity Law, and the Data Security Law.

Since the App does not collect any personal data, the data protection requirements under the EU General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA) do not materially apply. Nonetheless, we are committed to protecting your privacy in accordance with the highest standards.
