Terms of Service

Who you are agreeing with

PatternsRadar is operated by Bitmask LLP ("we", "us"), a limited liability partnership registered in India (ACX-4249), with its registered office at Wagale Estate, Thane, Thane Maharashtra, India.

By creating an account or using PatternsRadar at patternsradar.com, you accept these terms. If you do not accept them, do not use the service.

You must be at least 18 years old and legally able to enter a contract.

What this service is, and what it is not

PatternsRadar is a stock screener: you write the filter, it runs that filter over historical end-of-day market data and returns the instruments that match.

We are not registered with SEBI as an investment adviser or as a research analyst, and nothing here is investment advice, a recommendation, or a solicitation to buy or sell any security. A scan result is a list of instruments matching criteria you chose. A hit-rate replay is a historical statistic about past sessions, not a prediction and not a claim about what any scan will do next.

Every investment decision you make is yours. Consider taking advice from a SEBI-registered investment adviser before acting on anything you find here.

The data

Price, volume and delivery figures originate in the National Stock Exchange of India's published end-of-day files, by way of the open-source eod2 dataset, and are adjusted for splits and bonuses. Fundamental and derivative figures originate in exchange filings.

The data is end-of-day, not live, and it updates once per trading session after the close. It is provided as is. It may contain errors, gaps, stale rows and adjustment artefacts, and it is not the official record of anything. The exchange's own publications are. Verify anything that matters before you act on it.

Neither Bitmask nor PatternsRadar is affiliated with, endorsed by, or licensed by the National Stock Exchange of India. Exchange and index names are the trademarks of their owners and are used here only to describe what the data covers.

Your account

An account is for one person. Keep your password and your API keys to yourself: anything done with your credentials is treated as done by you, and a key you have shared is a key you are answerable for. Tell us promptly if you think either has been compromised.

Plans and payment

The free plan needs no payment. Paid plans are billed monthly in advance in Indian rupees through our payment provider, Razorpay, on a mandate you authorise. Prices include applicable taxes unless stated otherwise at checkout.

Each plan carries limits — saved scans, alerting scans, and request rates — which are published on the pricing page and enforced by the service. Renewal continues until you cancel. Cancellation and refunds are covered by our refund policy.

We may change prices. A change will not affect the period you have already paid for, and we will tell you before it applies to your renewal.

How you may use it

Use the service, the API and the MCP endpoint for your own research, within the limits of your plan. What you may not do is take the underlying dataset.

• Do not extract the market data in bulk, systematically or otherwise, whether through the website, the API, the MCP endpoint or anything else. Exporting the results of a scan you ran is fine; enumerating instruments to reconstruct the history behind them is not.
• Do not resell, republish, redistribute or licence the data, or use it to build or improve a competing dataset or data product.
• Do not share, sell or publish your API keys, or use another person's.
• Do not work around rate limits, plan limits or authentication, whether by rotating accounts, rotating addresses, or any other means.
• Do not attempt to disrupt the service or gain access to any part of it that is not yours, and do not use it for anything unlawful.

What we do not promise

The service is provided as is and as available. We do not warrant that it will be uninterrupted, error-free, or that the data is accurate, complete or current. We may change, suspend or withdraw features, and we may take the service down for maintenance.

Limitation of liability

We are not liable for any trading or investment loss, lost profit, lost opportunity, or any indirect or consequential loss arising from your use of the service or from any error, omission or delay in the data.

Our total liability to you for any claim relating to the service is limited to the amount you paid us in the twelve months before the claim arose. If you are on the free plan, that amount is nil.

Nothing here excludes liability that cannot be excluded under Indian law, including liability for fraud.

Ending it

You can stop using the service at any time and delete your account from the account page, which cancels any live subscription along with it.

We may suspend or close an account that breaches these terms, particularly the bulk extraction and redistribution rules above. Where it is reasonable to do so, we will warn first.

Changes to these terms

We may update these terms. The date at the top of this page says when they last changed, and a material change will be notified by email to registered users. Continuing to use the service after a change means you accept the updated terms.

Governing law

These terms are governed by the laws of India, and the courts at Thane have exclusive jurisdiction over any dispute arising from them.
