Calculator Vault

Privacy Policy for our secure vault and file hiding Android application.

Last Updated: September 3, 2026

Introduction

Calculator Vault ("the App") is designed to help users securely hide and protect personal photos, videos, and audio files on their Android devices. Protecting user privacy is our highest priority.

This Privacy Policy explains what information the application accesses, how it is used, and how it is protected.

Information Collection

Calculator Vault does not require account registration and does not collect personally identifiable information such as:

  • Name
  • Email Address
  • Phone Number
  • Contacts
  • Messages
  • Personal Documents

We do not upload personal photos, videos, audio files, or vault content to our servers.

These permissions are used only to access files selected by the user. The application does not access files without user interaction.

Third-Party Services

The application uses the following trusted third-party services to provide analytics, advertising, and billing functionality:

  • Google AdMob
  • Meta Platforms, Inc. (Meta App Events SDK)
  • Google Analytics for Firebase
  • Google Play Billing
  • Google Play Services

Each of these services may independently collect and process information as described in the sections below. Please review each provider's own privacy policy for further detail on how they process data.

File Storage and Processing

All vault operations are performed locally on the user's device.

  • Photos remain stored on your device
  • Videos remain stored on your device
  • Audio files remain stored on your device
  • Files are processed locally without being uploaded to our servers
  • Files are never sold or shared with third parties
  • Selected files may be moved into secure vault storage when requested by the user
  • Original files may be removed from their previous location after a successful transfer

When a user chooses to hide a file, the application may copy the file into secure vault storage and remove the original file from its previous location after the transfer has been completed successfully.

Google AdMob (Advertisements)

Calculator Vault uses Google AdMob to display advertisements within the application.

AdMob may collect and process certain information, including device identifiers, Advertising ID, IP address, and usage data, to provide and measure advertising services.

Some Google services integrated into the application may access the Android Advertising ID for analytics, fraud prevention, diagnostics, or service functionality.

Meta App Events (Advertising Measurement)

Calculator Vault uses the Meta App Events SDK, provided by Meta Platforms, Inc., to measure the performance of advertising campaigns run through Meta (Facebook and Instagram) Ads.

The Meta App Events SDK may collect and process information such as device identifiers, the Advertising ID, IP address, app installs, in-app events (such as onboarding completion and feature usage), and purchase events. This information is shared with Meta Platforms, Inc. to measure the effectiveness of advertising campaigns and to help deliver relevant ads.

Meta's collection and use of this information is governed by Meta's Privacy Policy, and, where applicable, by Meta's EU Data Transfer Addendum.

As described in the "GDPR and EEA/UK Users" section below, event collection through the Meta App Events SDK is disabled by default for users in the EEA, UK, and Switzerland until consent is obtained.

GDPR and EEA / UK Users

If you are located in the European Economic Area (EEA), the United Kingdom, or Switzerland, the General Data Protection Regulation (GDPR) and equivalent local laws apply to how your data is processed.

To support compliance with these laws, Calculator Vault uses Google's User Messaging Platform (UMP) SDK to determine whether a user is located in a region requiring consent, and to present a consent form before any consent-requiring data collection or ad personalization takes place.

  • Advertising personalization through Google AdMob is only enabled after consent is obtained through the UMP consent form, where required.
  • Automatic event logging and Advertising ID collection through the Meta App Events SDK are disabled by default (via AutoLogAppEventsEnabled and AdvertiserIDCollectionEnabled manifest settings) and are only enabled after the UMP consent flow confirms that ads may be requested for that user.
  • If consent is not granted, or the UMP flow determines ads cannot be requested, the app continues to function normally, but advertising personalization and Meta App Events tracking remain disabled for that session.
  • Users in the EEA, UK, and Switzerland may be shown a stricter minimum age requirement in accordance with local digital consent age laws, enforced through our Meta Platform's GDPR-restricted app settings.

Users in the EEA, UK, and Switzerland have rights under the GDPR, including the right to access, correct, delete, or restrict the processing of their personal data, and the right to withdraw consent at any time. Since Calculator Vault does not require account registration and does not store personal data on our own servers, most of these rights can be exercised directly by managing your consent choices in the app, adjusting your device's Advertising ID settings, or by contacting us using the details in the "Contact Us" section below.

Internet Usage

  • No personal photos, videos, audio files, or vault content are uploaded to our servers
  • Internet access may be used for analytics, advertising measurement, diagnostics, application services, and purchase verification
  • Communications with third-party services are encrypted where supported

In-App Purchases

Calculator Vault may offer optional premium features through Google Play Billing.

  • All purchase transactions are processed securely by Google Play
  • We do not collect or store credit card or payment information
  • We may receive information about successful purchases and entitlement status, which may also be shared with advertising partners (such as Meta) for advertising measurement purposes, subject to consent where required

Data Security

We take reasonable technical and organizational measures to protect user data and maintain application security.

  • Hidden files remain stored locally on the device
  • Files are not uploaded to developer servers
  • Access to vault content is restricted by the application's security mechanisms

Data Retention

Since files remain stored locally on your device, you control how long they remain within the application. Removing files from the vault or uninstalling the application may permanently delete vault-related data.

Children's Privacy

Calculator Vault is not intended for children under the age of 13. We do not knowingly collect personal information from children.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be reflected on this page by updating the Last Updated date.
