Last updated: 12 November 2026. This policy describes what this website actually collects. It applies to fii-diidata.mrchartist.com only.
Summary
You can use the dashboard without an account and without giving us your name, email or phone number. We do not run advertising or analytics trackers, we do not set tracking cookies, and we do not sell or rent personal data.
What we collect, and why
- Server and security logs. Like any website, our server and hosting provider process your IP address and browser details to deliver pages. We also keep a short-lived, in-memory count of requests per IP address to prevent abuse; it is not written to disk and is discarded within minutes.
- Browser push alerts (only if you turn them on). We store the push subscription your browser generates (an endpoint address and encryption keys) and the alert categories you chose, so that we can send the alerts. It does not contain your name or contact details. Turning alerts off in the dashboard deletes it.
- Email. If you write to us, we keep your message and address for as long as needed to deal with it.
Stored on your device
The dashboard saves a few preferences in your browser's local storage: light or dark theme, whether you have seen the welcome tour, table page size, a visit counter used to time the “add to home screen” hint, and a cached copy of the day's AI summary. A service worker caches the site's files so it loads quickly and can be installed as an app. None of this is sent to us, and you can clear it at any time from your browser settings.
Third parties
- Google Fonts serves the typefaces, so your browser contacts Google's servers (and Google sees your IP address) when a page loads.
- Hostinger hosts the website and may keep standard server logs.
- GitHub and Cloudflare (cdnjs) may be contacted by your browser as fallbacks, for the data file and the charting library respectively, only if our own server cannot provide them.
- Your browser's push service (for example Google, Mozilla or Apple) delivers alerts if you subscribe.
- Market-data and AI providers. Our server fetches data from NSE, NSDL and Yahoo Finance and sends market figures (never visitor data) to Groq to produce the AI summary.
- Links to X, YouTube, LinkedIn, WhatsApp and other sites take you to services with their own policies.
How long we keep it
Push subscription records are kept until you unsubscribe or the subscription stops working (expired subscriptions are removed automatically).
Your choices and rights
You can unsubscribe from alerts at any time as described above. You may ask us to tell you what we hold about you, correct it, or delete it, and you may withdraw consent for alerts, by writing to rohit@mrchartist.com. If you are not satisfied with our response you may have the right to complain to the data protection authority that applies to you.
Children
This site is intended for adults interested in financial markets and is not directed at children.
Changes
If this policy changes, the updated version will be posted on this page with a new date.
