Accessible Tech Labs India

1. The Zero-Knowledge Core Principle (90% of Our Web Tools)

The vast majority of utilities hosted on our platform execute entirely inside your web browser using modern web technologies like the HTML5 Canvas API, Web Audio API, Web Crypto API, and WebAssembly. When you use these tools, your files and text stay strictly inside your physical device's temporary memory (RAM):

• Document Utilities: PDF Merger, PDF to Text, Text to PDF, Image to PDF, PDF to Image, and Text Merger assemble and convert files locally. Not a single byte of your documents is ever transmitted to an external server.
• Image & Graphic Workstations: Professional Image Converter, Image to Icon Maker, and Text to Image render pixels directly on your device's graphics engine.
• Cryptographic File Vault: Files encrypted or decrypted using our AES-256 vault are processed using your unique password directly on your CPU. If you close the tab, the volatile key is erased instantly. We do not hold a master key or backdoor.
• Braille Document Creator: Plain text is compiled into Grade 1 Braille and Bharati Braille entirely client-side, generating .BRF files without online network requests.
• Digital Signature Generator: Your name and handwritten typography are drawn locally on a canvas and saved as a PNG. No biometric signatures are recorded or stored.
• Universal Visual Assistant: Live camera frames for color identification and ambient light reading are analyzed frame-by-frame in local browser memory and discarded immediately. No video is recorded or streamed online.

Because these utilities do not upload your content to any remote server, Accessible Tech Labs India cannot view, inspect, leak, or sell your files even if requested to do so.

2. Tools That Connect to External APIs (Data Minimization)

A small subset of our online tools requires public data from third-party networks to function. We design these tools with strict data minimization so your personal identity remains completely separated from the query:

• Live Weather Telemetry: Queries open meteorological nodes (Open-Meteo) using only the city name or browser-approved GPS coordinates you request. No search history is logged or tracked.
• DNS Reconnaissance & IP Forensics: Queries global resolution nodes directly to return network routing records. Your lookup history exists only on your screen.
• Zero-Knowledge Password Leak Checker: Implements the mathematical k-Anonymity protocol via the secure Pwned Passwords framework. Your device hashes your password with SHA-1 locally and sends only the first 5 characters of the hash. Your real password never leaves your computer.
• Global OSINT Breach Radar: Queries public breach intelligence endpoints (XposedOrNot) to check whether an entered email address has appeared in past public database leaks. The memory buffer purges immediately after the report renders.
• Temporary Email Generator: Connects to open disposable mail networks (mail.tm) to generate volatile inboxes for verification codes. The session and incoming messages are destroyed when you reset or close the tool.
• Global Payload Drop & Sovereign Nexus: File transfer and peer-to-peer communication establish direct WebRTC cryptographic tunnels between sending and receiving endpoints with ephemeral session tokens.

We encourage users to review the independent policies of third-party public networks (such as Open-Meteo or GitHub API) when using online lookup features.

3. Certified Windows Desktop Applications

Accessible Tech Labs India distributes its native graphical Windows applications—including ATL Media Downloader, ImageMaster Studio, and Media Composer Engine—exclusively through the official Microsoft Store.

• Zero Background Telemetry: Our desktop software does not install clandestine background services, tracking daemons, or usage telemetry modules.
• Local Hardware Execution: Features such as VLC-powered playback, format conversions, EXIF metadata stripping, and offline AI vocal extraction run entirely on your local CPU, GPU, and RAM.
• Media Sovereignty: What you download, edit, convert, or record belongs exclusively to you. Our applications never upload your video libraries, watch histories, or recordings to our laboratory.

4. Official NVDA Screen Reader Add-ons

Our official screen reader extension, the ATL Productivity Suite, is officially vetted, approved, and hosted on the NV Access Add-on Store under the GNU General Public License Version 2.0 (GPL-2.0).

As of version 2.1.0, our development team has completely removed the legacy telemetry module and all background tracking routines. The add-on runs 100% locally on your machine with zero external network dependencies, ensuring that your screen reading workflow, keystrokes, and system diagnostics remain completely private.

5. Technical Support & The 7-Day Auto-Purge Protocol

When you submit a problem report or feature suggestion through our Helpdesk Portal (`support-system/`), we collect only the information necessary to resolve your technical inquiry: your name, email address, selected product category, and description of the issue.

• Ticket Token Security: You are issued an 8-character token (such as ATLIXX99). You can track engineering resolution directly on our live tracking page without creating an account or password.
• Confidential Internal Notes: Private engineering notes between our core team are strictly separated in our database and are mathematically excluded from the public tracking API.
• The 7-Day Auto-Purge Protocol: To uphold our commitment to data minimization, once an issue is verified, resolved, and closed by our engineering team, our automated database script permanently deletes the ticket record after 7 days. No archived personal logs remain.
• User Communication: If an engineer replies to your inquiry, the notification is sent directly to your email. We do not use your email address for promotional marketing or spam.

6. Training Program & Student Data

Accessible Tech Labs India conducts free two-month online training programs focusing on Basic to Advanced Computer Skills and Cyber Safety Awareness. When you enroll in a batch, we receive your voluntarily provided contact details to schedule live Google Meet sessions and issue completion certificates. We never sell student rosters or share attendee contact details with third-party advertising companies.

7. Voluntary Financial Contributions

Supporting our laboratory is entirely voluntary. Our financial reception gateway is configured exclusively for National (Indian) Donors via the Unified Payments Interface (UPI) architecture to our official VPA. We do not operate third-party merchant payment gateways, and we never collect, store, or process your credit card numbers, bank passwords, or debit credentials.

8. What We Will NEVER Do

To ensure absolute transparency and build permanent trust with our global community, Accessible Tech Labs India formally commits to the following covenants:

• No Mandatory Accounts: We will never force users to create accounts, provide phone numbers, or log in just to convert a document or use our web tools.
• No Tracking Cookies: We do not deploy behavioral tracking cookies, cross-site advertising pixels, or analytics trackers on our main website.
• No Monetization of User Data: We do not sell, rent, lease, or trade personal information to data brokers, advertising agencies, or commercial aggregators under any circumstances.
• No Dark Patterns: We will never trick users into clicking misleading download buttons, installing bloatware, or subscribing to hidden payment plans.

9. Data Security & User Responsibilities

While we minimize data collection to the absolute zero-knowledge baseline, security is a shared responsibility. Because tools like our Cryptographic Vault and Offline Cleaners execute locally, your security posture depends on your own device's hygiene. Always keep your operating system updated, maintain strong unique passwords, and ensure you retain backups of critical files before performing bulk conversions.

10. Contact Information & Policy Updates

We may revise this Privacy Policy periodically to reflect newly engineered tools, Microsoft Store updates, or enhanced accessibility standards. Any updates will be published directly on this page with a revised effective date.
