Calculator Hide App Privacy Policy

Your privacy is our foundation. Calculator Hide App is designed from the ground up to keep your data private, encrypted, and under your control.

Last Updated: March 1, 2026

1. Introduction

Welcome to Calculator Hide App ("we", "us", or "our"). This Privacy Policy explains how our calculator hide app collects, uses, and protects your personal information when you use our mobile application available on Android and iOS platforms. We are committed to ensuring your privacy is protected at every level.

2. Information We Collect

2.1 Information You Provide

  • Account Data: When you create an optional cloud backup account, we collect your email address solely for authentication purposes.
  • Support Communications: If you contact us for support, we may collect your name, email, and the contents of your message.

2.2 Information We Do NOT Collect

Calculator Hide App operates on a zero-knowledge architecture. This means:

  • We never access, view, or store your hidden photos, videos, documents, or files.
  • We never collect your secret PIN or biometric data.
  • We never track which apps you choose to hide.
  • Your vault contents are encrypted with AES-256 encryption and stored exclusively on your device.

2.3 Automatically Collected Data

  • Device Information: Device model, operating system version, and app version for crash diagnostics.
  • Usage Analytics: Anonymous, aggregated usage patterns (e.g., feature popularity) that cannot be traced back to individual users.

3. How We Use Your Information

We use the limited information we collect to:

  • Provide, maintain, and improve Calculator Hide App's functionality.
  • Deliver customer support and respond to your inquiries.
  • Send critical updates about security patches or service changes (opt-in only).
  • Analyze anonymous usage trends to improve features and performance.

4. Data Encryption & Security

All files stored in the Calculator Hide App vault are encrypted using AES-256 encryption — the same encryption standard used by banks, governments, and military organizations worldwide. Your encryption keys are derived from your personal PIN and are never transmitted to our servers.

Additional security measures include:

  • Biometric authentication (fingerprint and Face ID) support.
  • Intruder detection with automatic selfie capture.
  • Decoy vault functionality for plausible deniability.
  • Auto-lock on app switch or screen timeout.

5. Data Storage & Retention

Your hidden files are stored locally on your device only. Calculator Hide App does not upload, sync, or transmit your vault contents to any cloud server unless you explicitly enable the optional Cloud Backup feature. If you use Cloud Backup, your data is end-to-end encrypted before leaving your device — we cannot decrypt it.

6. Third-Party Services

Calculator Hide App may use the following third-party services:

  • Analytics: For anonymous usage statistics (no personal data shared).
  • Crash Reporting: To identify and fix bugs (device info and crash logs only).

We do not sell, trade, or share your personal information with third parties for marketing or advertising purposes.

7. Children's Privacy

Calculator Hide App is not intended for use by children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us at privacy@calculatorhideapp.com and we will delete it promptly.

8. Your Rights

Depending on your location, you may have the following rights regarding your data:

  • Access: Request a copy of any personal data we hold about you.
  • Deletion: Request deletion of your account and associated data.
  • Correction: Request correction of inaccurate information.
  • Portability: Request your data in a machine-readable format.
  • Opt-Out: Unsubscribe from any optional communications at any time.

9. 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 "Last Updated" date. We encourage you to review this policy periodically. Continued use of Calculator Hide App after changes constitutes acceptance of the updated policy.
