No telemetry

Your activity never leaves your device. No analytics, no tracking, no data collection of any kind.

No accounts

Install and use. No sign-up, no email required, no subscription gates hiding core features.

Runs locally

Processing happens on your machine. Cloud is optional, never required, and never assumed.

The lab

A one-person studio.

Cheppulabs is run by Anish Monci Varghese — a former Indian Air Force officer turned project manager and software builder. The kind of person who believes tools should work quietly in the background, never ask for your data, and earn their place on your device.

Every product ships with three non-negotiables: privacy by default, focus over feature-creep, and the craft that makes software feel worth keeping. No telemetry. No dark patterns. No bloat.
