Privacy Policy for All File to ZIP Converter

Last updated: September 24, 2026

Einviteme Studio (“we”, “our”, or “us”) operates the mobile application All File to ZIP Converter (the “Application”). This page informs you of our policies regarding the collection, use, and disclosure of personal data when you use our Application and the choices you have associated with that data.

By downloading, installing, or using the Application, you agree to the collection and use of information in accordance with this Privacy Policy.

1. 100% Local & Offline Processing (No Cloud Storage)

  • On-Device Operations: All compression, archiving, extraction, password encryption, and file management operations are performed 100% locally on your device.

  • Zero File Uploads: We do not operate any external file storage servers. Your files, documents, photos, audio, and videos never leave your device, and are never uploaded, shared, or stored on any remote cloud server by this Application.

2. Device Storage Access & Least-Privilege Permissions

In strict compliance with Google Play Developer Program Policies:

  • No Broad Storage Permissions: The Application does not request or use invasive or broad storage permissions such as MANAGE_EXTERNAL_STORAGE, READ_EXTERNAL_STORAGE, or WRITE_EXTERNAL_STORAGE.

  • Storage Access Framework (SAF) & Photo Picker: The Application exclusively utilizes Android’s official Storage Access Framework (SAF) and the native Android Photo Picker. This ensures that the Application only has temporary read/write access to the specific files you explicitly select and approve.

3. Password Security & Cryptography (AES-256)

  • When you choose to protect an archive with a password, the Application applies industry-standard AES-256 bit encryption directly within the ZIP file format.

  • We do not collect, transmit, log, or store your passwords.

  • Important: Because encryption is handled strictly offline and we do not keep copies of your passwords, forgotten passwords cannot be recovered.

4. Personal Data Collection

We respect your personal privacy:

  • We do not collect, store, sell, or rent personally identifiable information (PII) such as your real name, email address (unless you contact us directly for support), phone number, physical address, contacts, or GPS location.

5. Third-Party Services & Advertising (Google AdMob)

The Application uses Google AdMob to display advertisements (Banner, Interstitial, Native, Rewarded, and App Open ads) to support ongoing maintenance and development.

Third-party service providers like Google AdMob may collect and process pseudonymous information in accordance with Google’s Privacy Policy, which may include:

  • Pseudonymous device identifiers (such as Google Advertising ID / AAID)

  • Device model, operating system version, and general network/carrier information

  • Ad performance, interaction, and diagnostic crash data

For more details on how Google processes data for advertising, please review:

6. Children’s Privacy

The Application is a general productivity tool and does not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13.

7. Security of Your Data

The security of your personal data and files is paramount to us. Because all file processing and encryption tasks happen entirely on your physical hardware without network transit, your data remains within your direct control at all times.

8. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the “Last updated” date at the top. You are advised to review this Privacy Policy periodically for any updates.
