Privacy Policy

1. 100% Client-Side Processing Architecture

Traditional online utility websites upload your private files to remote cloud servers for processing and stream back the result. DGNTool fundamentally rejects this outdated, high-risk paradigm.

All computational workloads on DGNTool execute entirely inside your local browser memory (in-memory execution):

• PDF Utilities (Merge, Split, Rotate, Compress): Executed locally via WebAssembly and modern JavaScript engines. Your documents never traverse network cables.
• Image Utilities (Convert, Resize, Crop, Compress): Handled via HTML5 Canvas and WebGL APIs using your local GPU/CPU hardware acceleration.
• Developer & Security Tools (JSON Formatter, Base64, Hash, Password Generator): Processed with hardware-level security via the native browser WebCrypto API.
• Instant Ephemerality: The moment you close the browser tab or refresh the page, all transient in-memory buffers are permanently purged.

2. Data We Never Collect or Store

Our security ethos is simple: data that is never collected can never be breached, leaked, or subpoenaed.

We do not retain upload logs, personal identity records, passwords, financial calculations, or uploaded multimedia on any server.

• Zero account databases: No sign-ups, registrations, or login credentials required.
• Zero input harvesting: We never log or inspect texts, source code, or numbers entered into our tools.
• Zero file archiving: Your files are never sent to S3 buckets, cloud databases, or external storage.

3. Local Browser Storage (LocalStorage) Usage

To enhance your user interface experience without compromising privacy, we utilize browser HTML5 LocalStorage instead of tracking cookies:

This data remains strictly on your local machine and is never transmitted to our backend. You can wipe it at any time by clearing your browser cache.

• dgntool_theme: Remembers your interface display preference (Light, Dark, or System mode).
• dgntool_favorites: Stores tool identifiers you have bookmarked for rapid access.
• dgntool_recent: Displays your recent local calculations on your screen.
• dgntool_consent: Records your cookie and privacy consent preferences.

4. Advertising Partners & Google AdSense Disclosure

To maintain our utility suite 100% free and accessible to everyone worldwide, we collaborate with third-party advertising networks, including Google AdSense.

Third-party vendors, including Google, use cookies to serve ads based on a user’s prior visits to our website or other websites on the internet.

Google’s use of advertising cookies enables it and its partners to serve ads to our users based on their visits to dgntool.com and other sites across the web.

5. Server Logs & Edge Security Infrastructure

When accessing DGNTool, standard edge firewall logs (IP addresses, user-agent strings, referring URLs, and timestamps) are briefly processed solely for preventing DDoS attacks, blocking malicious bots, and maintaining infrastructure stability. These transient technical logs are never linked to personal profiles.
