What we keep, and what we don't
ScalperSense has no accounts and no login, so there is no profile of you to keep. Almost everything you personalise stays inside your own browser. This page says exactly what leaves it.
What stays in your browser
Your watchlist, holdings, journal entries, price alerts and page preferences are stored in your browser's localStorage. They are never uploaded, so they don't follow you to another device, and clearing your browser data deletes them permanently. We cannot recover them, because we never had them.
What the server records
- Standard web logs. Like any web server, ours records the IP address, timestamp, page requested, referrer and browser user-agent for each request. These are used to keep the site running and to investigate abuse or faults.
- Market data caches. The bulk of what we store is NSE and BSE figures — option chains, index prices, open interest. That's market data, not personal data, and it is discarded after two days.
- Messages you send us. If you use the contact form, the name, email address and message you type are emailed to the site's maintainer and kept so the conversation can be picked up again. Nothing you send there is used for marketing.
We do not sell, rent or trade any of it, and we don't run analytics that build a profile of you across sites.
Advertising
This site carries advertising through Google AdSense to cover its hosting. Google and its partners use cookies and similar technologies to serve ads, and may use your prior visits to this and other websites to show ads they judge relevant.
You can control this directly with Google, independently of us:
- Turn personalised advertising off at adssettings.google.com.
- Read how Google uses data from sites that use its services at policies.google.com/technologies/partner-sites.
- Opt out of third-party vendor cookies at aboutads.info.
Blocking cookies in your browser also works. The site functions normally without them.
Other services your browser contacts
Loading a page here causes your browser to fetch a few things from other companies, which means those companies can see your IP address and that you visited:
- Google Fonts — the typefaces the site is set in.
- Google AdSense — the advertising described above.
- A public CDN — part of the stylesheet on some pages.
Market data itself is fetched by our server, not by your browser, so NSE and BSE never see your address.
Children
This site is meant for adults who participate in Indian financial markets. It is not directed at children, and we do not knowingly collect information from them.
Your choices
Because we hold nothing that identifies you beyond server logs and any message you chose to send, most requests are simple: clearing your browser data removes everything held locally. If you have written to us and want that correspondence deleted, ask through the contact form and it will be.
Changes
If this policy changes, the date above changes with it. Continuing to use the site after that means you accept the revised version.
