Политика конфиденциальности

Last updated: 2026. At ToolsTier, document privacy and data sovereignty are fundamental architectural tenets, not marketing afterthoughts. This Privacy Policy details our technical measures guaranteeing that your files, photos, credentials, and personal workflows remain strictly under your control.

1. Core Architecture: Zero Server Uploads (Client-Side Execution)

Unlike conventional web-based PDF utility platforms, ToolsTier operates on an uncompromised 100% client-side execution model. When you select, drag, or drop a file into any tool (including PDF, Word, Excel, PowerPoint, or raster images):

• Your file is never transmitted to our servers or any third-party infrastructure.
• No temporary file caches, intermediate buffers, or persistent cloud copies are ever created.
• All byte parsing, layout computation, raster manipulation, compression, e-signatures, and optical character recognition (OCR) run locally in your browser's sandboxed environment via WebAssembly, JavaScript, and HTML5 Canvas.
• Closing the browser tab instantly flushes all session data from your device's active memory.

2. Data We Never Collect

In accordance with our strict data-minimization ethics, ToolsTier affirms:

• No mandatory user registration, login credentials, or email collections are required to use the suite.
• We never inspect, parse, or scrape document text for machine learning training, behavioral targeting, or analytics.
• We do not sell, rent, or distribute personal information to advertising brokers or data vendors.

3. Client-Side Local Storage

We utilize your browser's localized storage mechanisms (localStorage) solely to preserve interface configuration parameters:

• Your preferred language setting (Arabic vs English).
• Visual theme configurations (such as dark mode preferences).

These entries reside solely on your client device, contain zero telemetry data, and can be purged at any time via your browser settings.

4. Third-Party Infrastructure

To ensure high rendering speeds and stable typography, we rely on established content delivery networks:

• Google Fonts: Web fonts load securely from Google edge servers, governed by standard network protocol logs.
• Public Content Delivery Networks (CDNs): Public helper libraries (such as open-source pdf.js character tables) are fetched over secure CDN layers with no access to user file contents.

5. Browser-Based Machine Learning & Biometrics

Our AI-driven modules—including Background Removal, Image Upscaling, Face Blurring, and OCR—utilize lightweight neural networks executed entirely on your local GPU/CPU via WebAssembly and WebGL. Photographic frames, biometric facial geometries, and scanned corporate memos are evaluated strictly in local memory and are never uploaded to remote inference clouds.

6. Global Regulatory Compliance (GDPR, CCPA, HIPAA Alignment)

Because ToolsTier never collects, stores, or processes personal data on remote servers, our zero-upload architecture inherently satisfies the stringent data-handling requisites of the European General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA), and corporate HIPAA data-segregation mandates.

Browser Memory Sandboxing & Process Isolation

All ToolsTier utilities execute within the strict confines of your browser's security sandbox. Under modern operating system architecture, sandboxed web processes are physically blocked from inspecting external file paths or transmitting unsanctioned network packets. Memory buffers allocated during document processing reside in ephemeral TypedArray allocations that are completely purged from physical RAM via browser garbage collection upon tab closure.

Protecting Biometric Snapshots, Signatures & Financial Records

When executing sensitive operations such as face blurring, e-signature stamping, or optical character recognition on banking ledgers, zero raster frames or vector paths leave your local device. Local execution satisfies corporate non-disclosure agreements (NDAs), legal work-product doctrines, and strict patient privacy standards.

Digital Hygiene Best Practices for End Users

To maximize document security, always verify that your connection displays a verified SSL/TLS lock icon (HTTPS) in the browser URL bar, maintain updated browser software to benefit from the latest hardware memory isolation defenses, and retain offline master backups of critical contracts.

Verification of Local Runtime and Network Audit

We invite enterprise system administrators and cybersecurity specialists to verify our claim by monitoring browser developer network tabs during document manipulation: zero API requests with payload data are transmitted, confirming total local computational isolation and complete file confidentiality.
