Last updated: 25 October 2026
1. Who is responsible for your data
Revenin Technologies, a sole proprietorship of Tarun Kumar, runs RateAnalyser, and decides what happens to the data described here. Under the Digital Personal Data Protection Act, 2023, that makes us the Data Fiduciary.
- Business name
- Revenin Technologies
- Kind of business
- Sole proprietorship
- Proprietor
- Tarun Kumar
- MSME registration
- Udyam registered
- Address
- 465, Near Shiv Mandir, Wazirabad, Delhi-110054

2. What this policy covers
This policy covers RateAnalyser.
| Service | Address | Do you need an account |
|---|---|---|
| RateAnalyser | analysis.revenin.com | Yes, to open the full rate analysis. The summary of every item is open to all |
Please read it before you make an account on RateAnalyser, because you accept it when you sign up. If anything here is not clear, write to admin@revenin.com and we will explain it.
3. Your account
- Your mobile number. Every RateAnalyser account is a mobile number
- Your name
You sign in with a code sent to your mobile. RateAnalyser has no passwords.
4. What you open
- The items you open free. Every mobile number can open 3 items free. We keep a scrambled copy of your number with them, because the 3 free items belong to the number and not to the account.
- Your passes. Which pass you have, when it starts and when it ends, and whether it came from a payment.
- How much you use it each day. A count of the items you view and the files you download each day, for the fair use limit in our Terms. It is a number for each day, not a list of the items.
- Changes you save. When you press Save on an item, the rates you changed and the name you give them.
- Your justifications. The Schedule of Work you check in Justification, as you confirm it: each item, quantity and rate, the tender details, the market rates you type, and your decision and remark on each item. With your free justifications and free AI readings we keep the scrambled copy of your number too, because they belong to the number.
- Your AI readings. How many you have, and how many you have used.
The file you upload for AI reading is deleted as soon as it is read. It goes to the AI and comes back as rows you can see and correct, then we delete the file, even when the reading fails. We keep what the AI read from it, and the rows as you confirmed them, to see where our AI reading goes wrong and make it read better. Nobody else can see them, and deleting a justification does not delete them.
5. Rates you change
When you change a rate on an item to see the new cost, the change is kept in the page address in your browser. That is why you can send the link to somebody and they see the same figures, and why it is gone when you close the page without saving the link. We do not keep it on our servers unless you press Save. Then we keep your changes and the name you give them, until you delete them or close your account.
6. Payments on RateAnalyser
- Which pass or pack of AI readings you bought, when, and how much you paid
- The order and payment reference from Razorpay, how you paid (for example UPI or card) and whether it went through
- The details for your tax invoice: your name, your state and the email you give for the invoice, and if you add your firm's GSTIN, the firm's name, address, pincode and GSTIN. We keep them so the form is filled in next time, and we send your tax invoice to that email.
We do not keep the email, mobile number or UPI id you give on Razorpay's payment page, and we never see your card number, your UPI PIN or your bank login. You give those to Razorpay on its own payment page.
7. Technical records on RateAnalyser
- Your signed in devices, with the IP address, the browser and how you signed in. One account works on 2 devices at a time, and your Account page lists them so you can sign one out.
- The codes we send you, with the IP address that asked for them, so we can stop somebody guessing codes
- A note of every AI reading, with the model used, the names and size of the files, and how much of the AI it used
8. Why we use your data
We process your personal data on the basis of the consent you give us when you sign up, and for the purposes below.
| What we do | Why |
|---|---|
| Make and run your account | So you can sign in and get back to your work |
| Send a code by SMS | So we know it is really you |
| Read your uploaded papers with AI | To save you the typing, when you ask for it |

We do not send you marketing messages unless you ask for them, and you can stop them any time.
9. Who else sees it
We use other companies to run our services. Each one gets only what it needs to do its job, and none of them may use your data for its own purposes.
| Company | What it does | What it gets |
|---|---|---|
| Vercel | Runs RateAnalyser, and counts visits to the Docs pages | Every request you make, with your IP address and browser |
| Supabase | Runs our database, in Mumbai | Everything in sections 3 to 7 that we keep |
| Cloudflare (R2) | Stores files | Only the file you upload for AI reading, until it is read |
| Anthropic | The AI that reads your papers | Only the paper you ask us to read, at the moment you ask |
| Razorpay | Takes payments | What you give on its payment page, and the amount |
| MSG91 | Sends the sign in code by SMS | Your mobile number and the code |
| ZeptoMail (Zoho) | Sends our emails | Your email address and what the email says |
| Runs our mailbox | The emails you send us, and a copy of your feedback |
The Docs pages, at analysis.revenin.com/docs, count their visits with Vercel Web Analytics, so we know which help pages people read and can make them better. It sets no cookies. It tells us the page, the page you came from, your country, and the kind of device and browser, and it never tells us your name, your IP address or anything you type.
When you send an email to admin@revenin.com, we get your email address and whatever you write or attach. We use it to answer you and to do what you asked. Our mailbox is run by Google.
When you send feedback from the Feedback page in RateAnalyser, we keep what you write, which product it is about, what it is about, your rating and the page you were on, with your account. We also send it by email to our own mailbox, with your name and your mobile number, so we can read it and answer you.
Besides these, we share your data only when the law requires it, such as an order from a court or a government authority, and only as far as the order goes. If we ever sell the business or turn it into a company, your data goes with it, and this policy keeps applying until we tell you otherwise.
10. Where your data is kept
- The database is in Mumbai, India.
- RateAnalyser's servers run in Mumbai.
- The files you upload to RateAnalyser until they are read are kept with Cloudflare, in the Asia-Pacific region.
- The AI reading on RateAnalyser happens outside India, mostly in the United States. Razorpay, Google, Cloudflare and Zoho may also handle some data outside India.
We send only what is needed, and we do not send data to any country the Central Government has stopped us from sending it to.
11. How long we keep it
| What | How long |
|---|---|
| RateAnalyser account, passes and free items | As long as your account is open. |
| RateAnalyser changes you save | Until you delete them or close your account. |
| RateAnalyser justifications | Until you delete them or close your account. |
| The file you upload to RateAnalyser for AI reading | Deleted as soon as it is read, even when the reading fails, and within a day at the most. |
| What the AI read from it | As long as your account is open, even after you delete the justification. |
| Your account, when you ask us to close it | Deleted within 30 days of the day you ask. RateAnalyser shows the date on your Account page. |
| Payment records and invoices | As long as Indian tax law says we must, even after you leave: 8 years. |
| Sign in records | On RateAnalyser, while your account is open. |
| The record of when Revenin opened or changed something of yours | Kept even after your account is closed. |
| Sign in codes | Only until they are used or they run out. |
| Feedback you send | As long as your account is open. The email copy in our mailbox is kept like your emails to us. |
| Your email to us | As long as we are talking or working with you, then 1 year after. |
12. When Revenin opens your account
Only the proprietor can open your workspace or your account, or change something in it, and only to fix a fault or when you have asked for help. He does it through a separate admin console, which asks him for a reason first.
If you want to see when he opened or changed something of yours, write to admin@revenin.com and we will switch on a list for your account. On RateAnalyser it is on your Account page. We can switch it off again if you ask.
13. How we keep it safe
- Every connection to our services is encrypted.
- Sign in codes and sign in tokens are stored scrambled, so nobody at our end can read them.
- One RateAnalyser account's data is walled off from another's inside the database itself, not only in the software.
- Every payment confirmation from Razorpay is checked with a signature before we give you anything, so a fake message cannot unlock a pass.
No system is perfectly safe. If your data is ever leaked, we will tell you and the Data Protection Board of India, as the law requires.
14. Cookies
RateAnalyser uses cookies only to keep you signed in and to keep the sign in safe. There is no advertising cookie and no tracking cookie from anybody else. If you block these cookies, signing in will not work.
15. What you can ask us to do
Under the Digital Personal Data Protection Act, 2023 you can ask us to:
- Tell you what we hold about you, and who we have shared it with. We can give you a copy as a file, with your details and your records, but not your files, your password or other people's details.
- Correct it if it is wrong, or complete it if something is missing.
- Delete it, unless the law makes us keep it, such as payment records.
- Withdraw your consent. Withdrawing it fully means we can no longer run your account, so we will treat it as closing your account and tell you before we do anything.
- Name somebody to act for you if you die or cannot act for yourself.
Write to admin@revenin.com. We answer within 30 days, and it costs nothing. We may ask you to prove who you are first, so that nobody else can ask for your data.
16. Children
Our services are for businesses and are not for anybody under 18. We do not knowingly collect data about children. If you think a child has made an account, write to admin@revenin.com and we will remove it.
17. Our Grievance Officer
If you are unhappy with how we have handled your data, write to our Grievance Officer and he will answer within 30 days.

18. Changes to this policy
We may change this policy. The new date goes at the top, and if the change is important we will tell you by email or on screen before it takes effect. If a change widens what we do with your data, we will ask you again before it applies to you.
