Tatsat
Privacy notice
Tatsat (tatsat.ai) is a free Hindi web and Android app that plays a ten-minute satsang each day: a spoken reflection on one verse of the Gita. It is run by Amit Upadhyay, an individual based in India. This notice explains what information is handled when you use Tatsat, with or without an account: where it lives, what it is used for, how long it is kept, and what your rights are under India's Digital Personal Data Protection Act, 2023.
Updated: 27 September 2026
In short
Tatsat can be listened to without an account. Then we ask for no name, email address, phone number or payment details, we set no cookies, and your practice record stays on your own device.
If you create an account, we keep your email address and your practice record on Tatsat's servers, so that it is the same on every device you use.
Like every website, we keep short-lived logs of visits, and we gather statistics about how the app is used that are not tied to your name or email address. The Android app also sends crash reports, which you can turn off.
From the account page you can download your data or delete your account at any time. We do not sell or rent any information, and we use none of it for advertising.
Who runs Tatsat
Tatsat is operated by Amit Upadhyay, an individual based in India. Under the Digital Personal Data Protection Act, 2023, he is Tatsat's data fiduciary, the person responsible for your personal data. He is also its grievance officer, and you can write to him at info@tatsat.ai.
What we do not collect
There is no password, and we collect no payment details. A phone number can be given only in a request for the sādhanā mālā, and only if you wish (see below). Your voice and your screen are never recorded, and no advertising identifiers are used.
Tatsat is intended for people aged 18 or over, and creating an account asks you to confirm this. We do not knowingly process children's data.
Without an account: on your own device
Your practice record stays in your browser on your own device: which days you listened to and where you paused, the days you completed, your answer to the one question asked after a satsang, your settings, and a random identifier for the device. None of it is sent to us until you sign in; when you do, it is added to your account once.
You can delete it at any time from the account page on the website, or by clearing your browser's site data.
The Android app keeps on the phone where you paused, your settings and a random device identifier; uninstalling deletes them.
With an account: what we keep
Your email address; your name, if you choose to give one; your language and time zone; the date you agreed to this notice; and your app preferences.
Your practice record: which satsang you listened to and when, where you paused, the days you completed, your answers to the one question, and the journeys you joined.
The morning reminder and its time; it stays off until you choose it.
A request for the sādhanā mālā (satsangs older than three days open on request): the reasons you chose, your own words and, if you give one, a phone number, used only to speak with you about that request. Every request is read by the person who runs Tatsat; it reaches them by email, and the answer comes to you by email. What is opened for you is recorded with your account.
A record of your sign-ins (when, and from what kind of device) and of your data requests, kept for security and to resolve grievances.
Two cookies on the device you sign in from: one keeps you signed in for up to 90 days, extended while you use it; the other remembers your language. Signing out removes both, and “Sign out on every device” on the account page ends every sign-in.
The Android app keeps the sign-in encrypted on the phone instead; signing out removes it (within seven days if offline) and your account's data from the phone. Only the app's settings go into the phone's backup.
We send only four kinds of email: the sign-in link, when you ask for it; the morning reminder, only if you have chosen it, and every one carries a link to stop it; the confirmation of a request to delete the account; and the answer to a request you made for the sādhanā mālā.
An address left with “Let me know” is kept on a separate list, not tied to any account, and used only for one note when the sādhanā begins.
The Android app's morning reminder is a notification set on the phone, not an email.
Logs and usage statistics
Like every website, our servers and the service that delivers the audio and the app's content log each request: the network (IP) address, the browser or app, what was requested, and the time. These logs are used only to run the service and keep it secure.
To understand how the app is used, we record events such as a satsang played or completed. An event carries an identifier of your device, or, for an event our server records, an identifier derived from your account that cannot be traced back to it; never your name or email address.
An event also carries the page or screen, your browser or app, your time zone and an approximate location worked out from your network address; the address itself is not kept. We look at these statistics only in aggregate, to understand how and where the app is used.
If the Android app crashes, freezes or meets a serious error, a report goes to a crash-reporting service: what went wrong and what the app was doing, the phone's model, the Android and app versions and the app's identifiers on that phone; never your name, email address, account or anything you listened to or read. The service is also told when the app is opened, to count crash-free use.
A switch on the Android app's account page turns all this and the app's statistics off on that phone, deleting unsent statistics and reports; the events our server records continue.
What the information is used for, and who receives it
The information is used only to play the satsang and remember where you paused; to run your account and keep your record the same on every device; to send the emails you asked for or chose; to answer a request for the sādhanā mālā; to understand in aggregate how the app is used and fix its crashes; to fulfil your rights requests; and to keep the service secure.
Five service providers process data on Tatsat's behalf, each only for these purposes: hosting and the database (Taiwan), delivering the audio and the app's content, usage statistics (European Union), email (its logs in the United States), and crash reports (worldwide). If you sign in with Google, Google knows that you signed in to Tatsat, and we receive only your email address and an identifier from it. Google Play delivers the Android app under its own terms and shows us install and stability figures, crash reports that name no one, and the reviews posted there. Beyond these, information is disclosed only where the law requires it.
How long information is kept
The record on your device stays until you delete it; your account and its record, as long as the account does. A phone number given in a request for the sādhanā mālā is deleted 90 days after the answer.
The record of sign-ins and data requests is kept for one year, the record of emails sent for 30 days, our server logs for about 30 days, usage statistics for one year, and crash reports for 90 days before deletion begins.
Deleting the account
Choosing “Delete the account” on the account page starts a seven-day period and sends you a confirmation email; within those seven days you can cancel with “Keep the account”. After seven days everything that identifies you is erased: your email address, name, preferences, sign-ins, the morning reminder and your requests for the sādhanā mālā.
The record of the satsangs you listened to and the days you completed stays under a number that leads to no person, so that aggregate figures stay true; the sign-in record completes its one year under the same number. Signing in again with the same email address creates a new account.
Security and data breaches
Every connection to Tatsat is encrypted. If a breach ever affects your personal data, Tatsat will inform you and the Data Protection Board of India, as the law requires.
Your rights and grievances
Under the Digital Personal Data Protection Act, 2023, you can ask what personal data is held about you, have it corrected or erased, withdraw your consent, have a grievance redressed, and nominate a person to exercise these rights on your behalf.
From the account page you can download everything your account holds as one file, change your language, time zone and name, and delete the account, which also withdraws your consent. For any other request, or without an account, write to info@tatsat.ai.
The grievance officer is Amit Upadhyay, at the same address. A grievance is acknowledged within 7 days and resolved within 30 days. If you are not satisfied with the answer, you may complain to the Data Protection Board of India.
