Privacy policy
TenderDhundo is run by Hi-Tech Engineers, Delhi. This page says what happens to your data when you use tenderdhundo.com. It is short because the site does very little with data.
The short version
- There are no passwords and no profile. You can sign up for two things: email alerts, which store your email address and the searches you chose, and the early-access list for Site, which stores your name, WhatsApp number, email address and how many sites you run. If you subscribe to alerts you can sign in — with a link we email you, never a password — to change your searches.
- We set one cookie of our own, and only if you sign in to manage your alerts: it remembers that it is you, for 30 days, and nothing else. Browsing, searching and reading the site set no cookie of ours at all.
- We use Google Analytics to measure how the site is used — which pages people reach, what they search for, which portals they click through to. It sets its own cookies. It is described below, and you can refuse it.
- Google AdSense serves the advertising on this site and sets its own cookies. It is described below.
- Nothing you type into the search box or the filters leaves your device — unless you ask us to email you alerts for a search, which sends us that search and nothing else.
- The only personal data we receive is what you give us when you sign up for alerts or the Site early-access list, and whatever you send us in an email.
What happens when you search
Searching and filtering happen entirely in your browser. The tender list is downloaded as data files and everything after that — your keywords, the filters you set, the tenders you open — is worked out on your own device and never sent anywhere.
We do not store your searches, because we never receive them.
What our host records
The site is served by Cloudflare Pages. Like any web host, Cloudflare processes technical connection data — your IP address, browser type, the page requested and the time — to deliver pages and protect the service from attacks. That processing is governed by Cloudflare's own privacy policy, and we do not receive reports from it identifying individual visitors.
Email alerts
If you sign up for alerts at tenderdhundo.com/alerts/, we store:
- your email address;
- the searches you chose — up to five, each one a state, work type, keyword, value range, and any city, department or portal, plus the name you gave it if you gave it one;
- whether you want the email daily or weekly;
- when you signed up and confirmed, and the wording of the consent you ticked.
That is the whole record. There is no name, no company, no registration number and no password, because none of them is needed to email you about tenders.
Nothing is sent until you click the link in the confirmation email. An address that is never confirmed is deleted automatically after seven days.
Signing in to change your searches
At tenderdhundo.com/alerts/manage/ you can add, rename and remove searches and change how often they arrive. To prove the address is yours we email you a sign-in link instead of asking for a password — there is no password to ask for. The link works once and expires after 15 minutes.
Signing in sets one cookie of ours, td_sess. It holds a random number that means "whoever is holding this signed in to that address", for 30 days. It is not shared with anyone, it is not used to measure anything, and it follows you nowhere: it is read only by the page that manages your alerts. Signing out deletes it, and so does unsubscribing.
We do not say whether an address is on the list. Asking for a sign-in link gets the same answer either way, so nobody can use the form to find out whether a competitor subscribes.
The sign-up is stored with Cloudflare, which hosts the site. The emails are sent through Resend (Resend, Inc., United States), an email delivery service, which receives your address and the content of each email in order to deliver it. We use your address for these alerts only: no newsletters you did not ask for, and it is never sold or passed to anyone else.
To keep from repeating ourselves, the computer that sends the alerts keeps a list of which tenders it has already told each subscriber about, one list per search. It is kept under a random number, not your email address.
Every email has an unsubscribe link. Using it deletes your address, all of your saved searches and any sign-in you still had, immediately; the list of what you have already been told about is deleted with the next nightly run. You can also ask us to do it at [email protected].
The Site early-access list
Site is a WhatsApp expense tracker we are building for contractors. If you join its early-access list at tenderdhundo.com/tools/whatsapp-expense-tracker/, we store:
- your name, WhatsApp number and email address;
- how many construction or work sites you run;
- when you signed up, and the wording of the consent you ticked.
We use these only to contact you about early access to Site: they are not added to the email alerts, and they are never sold or passed to anyone else. They are stored with Cloudflare, and sent to us in one email through Resend so that we know you have joined.
Your details are deleted automatically after 12 months. To have them deleted sooner, write to [email protected].
Google Analytics
This site uses Google Analytics, loaded through Google Tag Manager. We use it to see which pages are useful and which are not — for example that the Uttar Pradesh and department pages are the ones contractors actually reach, so those are the ones worth improving.
- What it collects: the pages you visit, roughly where you are (city level, from your IP address), your device and browser, how you arrived, and what you do on a page. It sets cookies to tell one visit from another.
- What it does not collect: your name, your email, or anything you type into the search box and filters. Those stay on your device, as they always have.
- We never see individual people. The reports are counts and averages.
- Tag Manager is the container that loads it. It lets us add or remove a measurement tag without changing the site's code, which also means we can add one without this page changing — so this section describes analytics generally, not one fixed tool.
How to refuse it. Install Google's opt-out add-on, or turn on "Do Not Track" or tracking protection in your browser — most browsers now block these cookies by default. Nothing on this site stops working if you do; there is nothing to log in to.
Google's own account of what it does with this data is in its privacy and terms and its technologies page.
If you email us
Mail to [email protected] is delivered through Cloudflare Email Routing to a mailbox we read. We receive whatever you put in the message — your name, email address, phone number if you include one — and we keep it so we can reply and to follow up on what you raised. We do not add you to any mailing list and we do not pass it to anyone else.
Ask us to delete your message and we will.
Links to other sites
Every tender listing links to the government portal that published it. Those portals are not ours, and their privacy policies apply once you leave this site. The same goes for any document you download from them.
Advertising
This site carries advertising through Google AdSense. The site is free to use and the advertising is what pays for running it.
Advertising appears on the pages this site wrote itself — the guides, the calculators, this page and the other information pages, and the home page. The tender listings carry no advertising. Those pages reproduce what government portals published, and we do not sell advertising against them.
What that means in practice:
- Google, as a third-party vendor, uses cookies to serve ads on this site. Google's use of advertising cookies lets it and its partners serve ads based on your visits to this and other sites.
- You can opt out of personalised advertising in Google's Ads Settings, or opt out of a third-party vendor's use of cookies for personalised advertising at aboutads.info.
- Google's own description of how it uses data from sites that use its services is in its technologies page.
- We do not give Google, or anyone else, a list of what you searched for. The search runs in your browser; we never receive it in the first place.
If you are in Europe
Visitors in the European Economic Area, the United Kingdom and Switzerland are shown a consent message before advertising cookies are set, and can consent, refuse, or manage the individual purposes. That message is Google's certified consent management platform, and the choice can be changed later. Refusing does not restrict anything on this site — the tender search, the guides and the calculators all work the same either way.
Analytics is not yet behind that message. The Google Analytics cookies described above are set when the page loads, without asking first. We are stating that plainly rather than implying a choice that is not currently offered. If you would rather not be measured at all, the opt-out add-on and your browser's tracking protection both work, and neither affects anything else on the site.
Children
The site is meant for contractors and businesses. It is not directed at children and we do not knowingly collect anything from them.
Your rights
For the personal data we hold — your alert sign-up, if you made one, and emails you have sent us — you can ask what we have, ask for a copy, or ask us to delete it. Write to [email protected]. We handle such requests in line with the Digital Personal Data Protection Act, 2023.
Changes
If this policy changes, the date at the top changes with it. Material changes, such as introducing advertising, will be described here rather than made quietly.
