Terms of Use

Last updated: 4 September 2026 · Opifex Labs, a sole proprietorship, Ghaziabad, Uttar Pradesh, India

1. The agreement

These terms govern your download, trial and use of LendaarMitra — GST 180-Day ITC Compliance ("the Software"), published by Opifex Labs. Installing or using the Software means you accept these terms and the End-User License Agreement shown during installation.

2. License

Trial: 14 days, full-featured, one trial per computer, free of charge.
Paid license: an annual subscription licensing one named user on one computer for the paid period. The current price is shown on the Pricing page.
The license is activated against your computer's hardware identity. You may move it to a new computer yourself using the in-app transfer option (at most once every 30 days).
The license is personal and non-transferable to another person or organisation without our written consent.

3. What you may not do

Share, resell, rent or sublicense your license key.
Reverse engineer, decompile, or attempt to bypass the license mechanism.
Use one license on multiple computers simultaneously.
Use the Software for any unlawful purpose.

4. Updates and support

An active subscription includes all Software updates released during the subscription period and email support at hello@opifex.in. When the subscription lapses, the Software stops working until renewed; your data and outputs (Excel files it produced) remain yours and remain usable.

5. Professional responsibility (important)

The Software reads a creditor ledger you supply, allocates payments against invoices, and computes indicative figures under the second proviso to section 16(2) of the CGST Act and interest under section 50. It is an assistive tool, not a source of legal, tax or audit conclusions, and its output is advisory. Every figure depends on the completeness and correctness of the ledger you give it — in particular on payments being recorded against the invoices they settle. You, the professional advising your client, remain solely responsible for verifying the figures and for every position, computation or filing you take on the basis of them. We accept no liability for decisions taken on the basis of the Software's output.

6. Ledger samples sent in for format support

LendaarMitra reads ledger exports from a number of accounting packages. When it meets an export it cannot read, it asks you to send us a sample so we can add support for that format. This section governs those files. It is in addition to, not instead of, the Privacy Policy.

6.1 What we ask for

To add support for an accounting package we do not yet read, we ask you to send a sanitised sample of the ledger export. LendaarMitra includes a Ledger Sanitiser for this purpose: it replaces names, GSTINs, PAN, contact details and monetary figures with stand-ins while leaving the file's structure intact, so we can see the layout without seeing your client's affairs. We ask for two or three exports from different clients using the same software, because a single file does not show the variations we must handle.

We ask you to run the Sanitiser before sending, and to review its output first. The mapping between real names and stand-ins is written to a separate review workbook that stays on your machine; do not send it to us.

6.2 Deletion of raw files

If you send a file that has not been sanitised, we delete it on receipt. We do not open it, copy it, forward it, or retain any part of it, and we delete the message it arrived in. We will tell you that we have done so and ask for a sanitised copy instead.

6.3 Retention

From a sanitised sample we retain only what is needed to build and keep supporting the parser for that format: the sanitised file itself, and a note of which accounting package and version produced it. We retain these for as long as LendaarMitra supports that format, because a parser that cannot be re-tested against the layout it was written for cannot be safely maintained.

We retain no raw file, no name mapping, and no client list. You may ask us to delete a sanitised sample at any time, and we will confirm when it is done.

6.4 Confidentiality

We treat every file you send as confidential. We do not share it with any other customer, publish it, use it in marketing or demonstrations, or disclose that a particular firm or client uses a particular accounting package. Access is limited to the people building the parser.

Nothing you send is used to train a machine-learning model.

6.5 What we promise about timing

When we add support for a new format we say it will arrive in an upcoming release. We do not commit to a date or a turnaround, and no statement elsewhere in the product or on this site should be read as one.

6.6 Scope

Format support covers machine-readable exports produced by accounting software. It does not cover scanned documents, photographed pages, or spreadsheets maintained by hand — a hand-maintained spreadsheet has no stable format to support. If a file falls outside this scope we will say so rather than leave the request open.

6.7 Your own duty

You remain responsible for your confidentiality obligations to your client. Sanitising a file before sending it is how you meet them, and it is why the Sanitiser is part of the product rather than a service we perform for you. Please satisfy yourself that the sanitised output is safe to send before you send it — the Sanitiser prints its own honest limits, and its review workbook lists every string it left alone.

7. Your data

The Software processes your files locally on your computer. We never receive them, except for a sample you choose to send us under section 6. The limited personal data we do process is described in the Privacy Policy.

8. Intellectual property

The Software, its design and branding are the property of Opifex Labs. You receive a license to use it, not ownership of it.

9. Liability

To the maximum extent permitted by law, our total liability arising out of or relating to the Software is limited to the license fees you paid in the 12 months preceding the claim. We are not liable for indirect or consequential losses, or for loss of data caused by hardware failure, other software, or misuse.

10. Termination

We may revoke a license without refund if these terms are materially breached (e.g., key sharing or attempts to defeat licensing). Refund-based revocations are covered by the Refund Policy.

11. Governing law

These terms are governed by the laws of India. Courts at Ghaziabad, Uttar Pradesh have exclusive jurisdiction.
