Yes. GSTfy is 100% offline. Your files, invoices, and client data stay on your PC. There is no cloud sync, no telemetry, and no remote access.

Does it need internet?

Only the online AI bill reader benefits from internet for highest accuracy. Everything else — GSTR-1/2B/3B, Kuber export, the offline OCR bill reader — runs without internet. The app is air-gap friendly.

How many PCs does one license cover?

One PC per license. The license is Ed25519-signed and machine-bound for security.

What happens after the trial?

You get every feature free for 30 days. After the trial there is a short grace period to activate. Activation is a single offline step.

Can I move my license to a new PC?

Yes. Get in touch and we’ll help you transfer the license to your new machine.

The cloud problem

Cloud GST tools are expensive, recurring, and risky with your client data.

Per-seat subscriptions, per-invoice caps, mandatory data uploads, and the constant worry: where exactly are my clients’ books being stored?

GSTfy

The entire workflow stays local. One-time license. Done.

Install on the PC you actually work on. AI extracts invoice data, GSTR-1 and 2B take shape, 3B summary auto-generates, Kuber export is one click — and nothing ever leaves the machine.
