Your money stays on your machine.

It runs on your device

Every calculation happens in your browser. Nothing is sent away to be worked out.

Only your PIN opens it

Your data is encrypted with a key made from your PIN. We do not have it, and we do not have a copy.

There is no account

No email, no password, no profile on a server. Nothing to breach, nothing to sell.

AI only if you ask for it

Off until you switch it on. With no key configured the AI never runs, and nothing is sent anywhere on your behalf.

Built on the rules, not on round numbers.

Every figure here is read from the same source the calculations use. If a limit changes, this page changes with it.

The current year, not last year’s

Slabs, the ₹75,000 standard deduction and the section 87A rebate are pinned to FY 2026-27. Residency already accounts for the Income-tax Act 2025 replacing the 1961 Act from April 2026.

Rules that differ by regulator

Nomination limits come from whoever sets them — 4 for a bank account, 10 for mutual funds — and where a regulator publishes no ceiling at all, like EPFO, it says so instead of inventing one.

Statutory limits at their real values

NRO repatriation is capped at USD 1,000,000 a financial year. Residency turns on 182 days, or 60 plus 365 across four years, with the relaxations that apply to you.

Why the detail matters

₹67,270 crore of Indian bank deposits sat unclaimed as of June 2025 (RBI) — largely because nobody knew the accounts existed.

Bring your own key

AI that runs on your account

No Trezoriq AI subscription and no model of ours in between. Nothing is metered, rationed or upsold.

  1. 1

    Get a key from a provider

    Gemini, OpenAI, Anthropic or OpenRouter. Gemini has a free tier that covers ordinary use.

  2. 2

    Paste it into Settings

    Settings → AI & Integrations. It is encrypted on your device, and each feature has its own switch.

  3. 3

    Use it, or do not

    Read a Form 16, draft a tax summary, ask about your own numbers. Leave the key blank and every calculator still works.

Where your key goes. Stored encrypted on your device. Each request passes it through our proxy to the provider, because browsers cannot call these APIs directly. We do not store it and do not log it.

What it costs. Whatever your provider charges, billed to you by them. Without a key the AI stays off and everything else is unaffected.
