This notice explains how TATHA VASTU PRIVATE LIMITED uses cookies and similar technologies on tathavastu.xyz and in the Tatha Vastu web app. It takes effect on 1 November 2026 and should be read with our privacy notice.
What cookies are
A cookie is a small text file a website stores in your browser. Similar technologies, such as local storage in the browser or on the site app, work the same way. Some are needed for a site to work at all. Others remember a choice you made or count how a page is used.
Cookies we use
| Type | What it does | How long it lasts | Can you turn it off |
|---|---|---|---|
| Strictly necessary | Keeps you signed in, protects forms against forgery, remembers which work order you had open | The session, or up to 30 days for a remembered sign-in | No. The app does not work without them |
| Security | Detects unusual sign-in attempts and repeated failed requests | Up to 24 hours | No |
| Preferences | Remembers settings such as the bill format preview or a closed notice | Up to 12 months | Yes, by clearing browser storage |
| Measurement | Counts page views and form submissions as events, without the content of what you typed or uploaded | Up to 12 months | Yes, through the choice we offer |
We do not use advertising cookies, and we do not let third parties place cookies on our pages to follow you across other sites.
The site app on a phone does not use cookies. It keeps a sign-in token in the phone's secure storage so a site engineer does not have to sign in at every visit, and the token is cleared when the user signs out or an administrator removes the user from the work order.
Cookies in the client bill room
A client's engineer or PMC who opens a bill room link gets only the strictly necessary cookies needed to keep the session and protect the certification actions. We do not place measurement cookies in the bill room, so a client user's checking of a bill is never counted for marketing.
Cookies we set are first-party: they are read only by tathavastu.xyz and the Tatha Vastu app, and they hold an identifier, not your name, email or the content of a bill.
Offline storage in the site app
The site app stores measurements, photographs and sketches on the phone until it can sync them. This storage is part of the service: without it, a measurement taken with no network would be lost. Data stored on the phone is cleared from local storage once it has synced and the user signs out.
What we never record
Uploaded bills, BOQs, measurements and calculator inputs never go to measurement or analytics tools. Events carry only their name and coarse details, such as the client type chosen in a form or the band of live work orders.
Your choices
- When you first visit, you can accept or decline measurement cookies. Declining does not change how the site works.
- You can change that choice at any time by clearing the cookies for tathavastu.xyz in your browser, which brings the choice back on your next visit.
- Most browsers let you block or delete cookies in their settings. Blocking strictly necessary cookies will stop you signing in.
Consent under Indian law
Where a cookie processes personal data and is not needed to provide the service you asked for, we rely on your consent, as the Digital Personal Data Protection Act, 2023 requires. Your consent is free, specific and can be withdrawn as easily as it was given.
Changes and contact
If we add a new type of cookie, we update the table above and the date at the top. Questions go to the Grievance Officer through the Grievance Officer form.
