Privacy Policy

Effective Date: 9/29/2026

1. Introduction and Scope

Welcome to DocMaster, a premier application meticulously developed and maintained by Gree Web Solutions. We are deeply committed to protecting your personal information and your fundamental right to privacy. This extraordinarily comprehensive Privacy Policy explains in painstaking detail how we collect, use, store, share, and safeguard your data when you interact with our mobile application and related services.

By accessing or using DocMaster, you signify that you have read, understood, and agree to our collection, storage, use, and disclosure of your personal information as described in this Privacy Policy. If you do not agree with our policies and practices, your choice is not to use our Application.

2. Local-First Data Storage & Uncompromising Security

DocMaster is architected from the ground up with privacy as its foundational pillar. We proudly operate on a strict Local-First Storage paradigm.

  • Zero Cloud Uploads: Your documents, scanned files, images, PDFs, and personal data remain stored strictly on your local device storage or your designated SD card. We do not automatically or manually upload your files to any remote server, cloud infrastructure, or third-party storage provider.
  • Military-Grade Local Encryption: Any hidden or secured documents within the application's secure vault are protected using advanced AES-256 local encryption algorithms. Access requires your chosen PIN, alphanumeric password, or biometric authentication (fingerprint/face recognition).
  • Key Custody: The cryptographic keys used for this encryption are generated and retained exclusively on your physical device hardware. At no point do these keys leave your device, meaning that Gree Web Solutions has absolutely no technical capability to decrypt or access your secured files.

3. Exhaustive Breakdown of Device Permissions

To provide you with an optimal, feature-rich document management experience, DocMaster relies on specific device permissions. We adhere to the principle of least privilege, requesting only those permissions that are fundamentally necessary for the application's core functionality:

  • STORAGE (READ_EXTERNAL_STORAGE / WRITE_EXTERNAL_STORAGE): Historically required on older Android versions to allow the application to read documents from your storage directories and write edited or newly scanned documents back to your storage.
  • MANAGE_EXTERNAL_STORAGE: For modern Android devices (Android 11+), this comprehensive permission is strictly required to allow DocMaster to effectively search, organize, read, and write document files across all of your device's publicly accessible directories. Without this, global document management is impossible.
  • CAMERA: This permission is required exclusively for the high-resolution document scanning feature. It empowers the app to activate your device's camera hardware to capture physical documents, perform optical character recognition (OCR), and convert them into pristine digital PDF formats. The camera feed is processed entirely locally on your device.
  • INTERNET & ACCESS_NETWORK_STATE: These standard permissions are essential to facilitate the fetching of critical application updates, the delivery of dynamically requested third-party advertisements, the verification of premium licenses, and the transmission of anonymized crash telemetry to improve application stability.
  • WAKE_LOCK: A minimal permission utilized occasionally to prevent your device processor from going to sleep while a large document conversion or intensive local encryption task is actively running.

4. Third-Party Advertising and Monetization (Ads)

Developing and maintaining a high-quality application requires substantial resources. To keep the core features of DocMaster entirely free for our global user base, we integrate with industry-leading third-party advertising networks. These networks employ sophisticated algorithms and may collect certain non-personally identifiable information, such as your device's Advertising ID, IP address, and general location data, to serve contextual and targeted advertisements. Our trusted advertising partners include, but are not limited to:

  • Google AdMob: Integrated for the seamless delivery of banner, interstitial, native, and rewarded video advertisements. Google's comprehensive privacy policies govern the use of data through AdMob.
  • Meta Audience Network: Utilized as a powerful mediation partner to augment ad fill rates and provide highly relevant commercial content to our users.
  • Unity Ads: Frequently employed for engaging video and rich media display advertisements.

Robust In-App Consent Controls: We rigorously comply with the General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), and other emergent global privacy frameworks. Users residing in the European Economic Area (EEA), the UK, and California will be presented with a Google User Messaging Platform (UMP) SDK consent dialogue upon their initial launch of the application. This allows you granular control to view, meticulously adjust, or entirely revoke your advertising privacy choices and consent parameters directly within the DocMaster Settings menu at any given time.

5. Advanced Analytics and Crash Telemetry

To continuously refine DocMaster, we leverage Firebase Crashlytics and Google Analytics for Firebase. These tools help us understand user navigation patterns, feature utilization rates, and critically, the technical root causes of application crashes. All analytical data harvested is fundamentally anonymized and aggregated. The telemetry payload includes metadata such as your device model, operating system version, the duration of your session, available memory at the time of a crash, and a stack trace of the application's internal functions.Absolutely no personal documents, scanned images, file names, or user-generated textual content are ever included in these diagnostic reports.

6. Specific Rights for European Residents (GDPR)

If you are a resident of the European Economic Area (EEA) or the United Kingdom, you are granted specific rights regarding your personal data under the GDPR. These include:

  • The Right to Access: You have the right to request copies of your personal data.
  • The Right to Rectification: You have the right to request that we correct any information you believe is inaccurate or incomplete.
  • The Right to Erasure: You have the right to request that we erase your personal data, under certain conditions.
  • The Right to Restrict Processing: You have the right to request that we restrict the processing of your personal data, under certain conditions.
  • The Right to Object to Processing: You have the right to object to our processing of your personal data, under certain conditions.
  • The Right to Data Portability: You have the right to request that we transfer the data that we have collected to another organization, or directly to you, under certain conditions.

To exercise any of these rights, please contact our Data Protection Officer using the contact information provided at the bottom of this document.

7. Specific Rights for California Residents (CCPA/CPRA)

Under the California Consumer Privacy Act (CCPA) and the California Privacy Rights Act (CPRA), California residents are afforded specific rights concerning their personal information:

  • Right to Know: You may request disclosures detailing the categories of personal information collected, the sources of that information, the business or commercial purpose for collecting or selling it, the categories of third parties with whom it is shared, and the specific pieces of personal information collected about you.
  • Right to Delete: You may request the deletion of your personal information collected by us, subject to certain legal exceptions.
  • Right to Opt-Out of Sale or Sharing: You have the right to direct us not to "sell" or "share" your personal information (as those terms are broadly defined under California law) to third parties for targeted advertising purposes.
  • Right to Non-Discrimination: We will not discriminate against you for exercising any of your CCPA rights. You will not be denied goods or services, charged different prices, or provided a different level of quality.

8. Data Retention, Archiving, and Deletion Mechanics

Because DocMaster is fundamentally a local storage utility, the vast majority of your data footprint exists solely on your personal hardware. Consequently, this data is retained exactly as long as you choose to keep the application installed on your device. Initiating a standard uninstallation procedure via your device's operating system will permanently eradicate the local data repository associated with DocMaster (excluding files you have explicitly exported or backed up externally). Anonymized telemetry data managed by our third-party analytics providers is subject to automatic cyclical deletion, typically spanning a retention window of 14 to 26 months, governed by their respective corporate data retention schedules.

9. Children's Online Privacy Protection Act (COPPA) Compliance

Our Application and Services are not purposefully designed for, directed at, or marketed to children under the age of 13 (or under the age of 16 in certain European jurisdictions). Gree Web Solutions does not knowingly or intentionally collect personally identifiable information from minors. Should we become aware that a minor has inadvertently transmitted personal data to our systems, we will immediately initiate protocols to expunge such information from our active databases. Parents or legal guardians who suspect their child has provided us with unauthorized data should contact us posthaste.

10. Iterative Modifications to This Privacy Policy

The digital landscape and regulatory environments are in a state of perpetual evolution. As such, Gree Web Solutions reserves the unilateral right to amend, modify, revise, or completely overhaul this Privacy Policy at our sole discretion and at any time. We will disseminate notifications regarding material changes by visibly publishing the revised Privacy Policy on this specific web page and updating the paramount "Effective Date." We strongly encourage all users to proactively review this Privacy Policy on a periodic basis to remain informed of our data stewardship practices. Your continued use of the Application following the posting of any modifications constitutes your explicit acceptance of the revised terms.
