THE LOCAL-FIRST ADVANTAGE

How Our Desktop Software Works (3-Step Workflow)

Unlike modern SaaS tools that hold your files hostage behind recurring monthly subscriptions, our software compiles straight to native machine instructions and runs 100% locally on your computer.

01

Download & Verify Checksum

Get your official 64-bit Windows portable binary or installer (Setup.exe). Every release includes a public SHA-256 cryptographic checksum so you can independently verify binary integrity.

SHA-256 Authenticated
02

0 Bytes Outbound Telemetry
03

Perpetual Ownership & Zero Monthly Fees

Pay once and own the software forever. No monthly billing surprises, no forced logins or cloud outages, with direct founder WhatsApp and email support for lifetime peace of mind.

Lifetime License • No Monthly Fees
LIVE IN-BROWSER CLIENT-SIDE SANDBOX

Think This Is Just Marketing Words? Prove Us Wrong in 5 Seconds.

Every SaaS on Earth claims they "care about privacy" right before uploading your files to AWS. We refuse to ask for your trust. Turn off your computer Wi-Fi or unplug your Ethernet cable right now, then compress an image, redact text, or compute a hash below. If a single byte leaves your machine or any tool fails, don't buy our software.

BUYER QUESTIONS & TRANSPARENCY

Frequently Asked Questions

Everything you need to know about licensing, offline execution, Indian domestic payments, and updates.

Does this software require an active internet connection to run? +

No. All 26 RQL commercial suites are 100% local-first and air-gapped. You can completely disconnect your Ethernet cable, turn off Wi-Fi, or run them in an offline secure vault.

Every algorithm, forensic PDF purge, AI speech model, and database transaction runs entirely on your local CPU and RAM with 0 outbound network sockets and 0 cloud telemetry.

Is this a monthly subscription or a one-time purchase? +

It is a 100% perpetual commercial license. You pay once and you own the compiled binary forever. There are zero recurring monthly SaaS fees, zero hidden renewal invoices, and zero cloud lock-ins. Once you purchase, the software is yours to run indefinitely.

How can Indian customers pay without an international credit card? +

We provide full native support for Indian buyers via direct UPI (Google Pay, PhonePe, Paytm, BHIM) and Net Banking.

Simply click the "WhatsApp VIP" button on any product card or reach Founder Mohammad Rehan directly at +91 7091518548. Your official tax invoice and verified license key are issued immediately upon UPI transfer.

What operating systems and hardware are supported? +

Official 64-bit releases are pre-compiled for Windows 10 and Windows 11. Because the engines are hand-engineered in pure native Rust (zero heavy Electron wrappers or Python runtimes), applications boot in under 1 second, consume less than 35MB of RAM, and run smoothly even on modest hardware.

What is your return and refund policy? +

We back every commercial license with our 7-Day Unconditional Money-Back Guarantee. If an RQL application fails to operate with 100% offline reliability or eliminate your recurring SaaS expenses, email Founder Mohammad Rehan directly at [email protected] for an immediate 100% refund. Zero hassle, zero questions asked.

How do updates, bug fixes, and support work? +

All commercial licenses include lifetime maintenance patches and critical security fixes for your major version. You also get direct access to founder support via WhatsApp and email ([email protected]).
