Why Algod runs on your machine, not our cloud

Ask most people to picture trading software in 2026 and they'll describe a web dashboard: you log in, paste your broker keys into a form, and a fleet of servers you'll never see runs your strategies for you. It's convenient. It's also a strange thing to accept from tools that touch your money and your alpha. When we started Algod we made the opposite bet — the whole app runs on your desktop, and nothing leaves it unless you place an order.

Your keys never take a trip

The most sensitive thing you hand a trading app is your Zerodha login. In Algod it's kept in your device's own secure storage — protected by your operating system and tied to your user account. It's never shown back to you in the app, never dropped into a log, and never sent anywhere. Algod uses it to reach your broker, and nothing else.

Everything else you create — watchlists, strategies, backtests, and every simulated and live fill — stays on your device. You can back it up, copy it to another computer, or delete it and start clean. There is no export button because there is nothing living somewhere else to export from.

Only one connection ever leaves

Inside, Algod keeps the part that draws your screens separate from the part that runs the trading math — but both live entirely on your computer and only ever talk to each other, never to the outside world. The single outbound connection in the whole product is to your Zerodha account, and it carries exactly two things: the market data you asked for and the orders you authorized.

  • No Algod account, no sign-up, no email wall to get through.
  • No analytics, no crash reporting, no silent phone-home.
  • No shared server that becomes a single, tempting target for attackers.
  • Your strategies stay yours — an edge you don't upload can't leak.
If a feature only works because your data sits on our servers, it's a feature we chose not to build.

Local-first isn't free of trade-offs, and we won't pretend otherwise. You own your backups, and you're responsible for keeping your machine secure — there's no support engineer who can reset things from the cloud, because there is no cloud. We think that's the right deal for software that trades your capital. Your strategies, your keys, your machine, and none of it is trading advice: algorithmic trading carries real risk, and running it privately doesn't change that.
