TermsTerms

This page covers three different relationships, and they are kept apart on purpose. Reading the site. Using the software we give away. And engaging us to build something.

The first two are governed entirely by what is written here. The third is not: if we have signed anything with you — a proposal, a statement of work, a master agreement — that document governs, and this page only fills gaps it leaves.

The free products are given away as they are, with no warranty. The paid work carries real commitments, and they live in the contract rather than on a website.

This website at par2labs.com is operated by PAR2 LABS PVT LTD ("PAR2 LABS", "we", "us"), a company registered in India. Using the site means accepting these terms. If you do not accept them, stop using it.

We may change these terms. The date at the top changes when we do, and the version in force is the one published at the time you use the site. A change that materially affects an active engagement is a matter for that engagement's contract, not for this page.

Read anything. Quote anything with attribution and a link. Share it. Use what you learn. The articles exist to be useful and we would rather they travelled.

What is not acceptable: attempting to gain unauthorised access to the site, its server or any connected system; scraping at a rate that degrades service for anyone else; probing, scanning or testing the security of the infrastructure without our written permission; using the site to distribute malware or unlawful material; or misrepresenting yourself as us.

Automated crawling is explicitly permitted within the rules published at par2labs.com/robots.txt, including by AI answer engines. Those rules are the permission; ignoring them is not.

The written content, design, code, diagrams, photography and brand marks on this site belong to PAR2 LABS or to the people we licensed them from, except where a page says otherwise.

Quoting for commentary, review, teaching or reporting is fine and needs no permission, and a link is appreciated. Republishing an article in full, using our name or marks in a way that suggests endorsement or partnership, or presenting our work as your own, is not.

Client work shown under Missions is published with that client's agreement. Their names and marks belong to them.

Everything published under Intel is engineering and commercial opinion, written at a point in time, about circumstances that may not be yours. It is not professional advice, and no relationship of adviser and client is created by reading it.

We check what we publish and we correct what we get wrong, but we do not warrant that any of it is complete, current or applicable to your situation. Regulations change, models get deprecated, prices move, and a figure that was right when written may not be right when read. Decisions with money or safety attached deserve advice from somebody who knows your specifics.

Where an article links out, the linked material is somebody else's and we do not control or endorse it.

The site is provided on a reasonable-efforts basis. There is no uptime commitment attached to it, and we may change, move or withdraw any part of it without notice. The hosted demonstrations are demonstrations; they may be reset, rate-limited or taken down at any time.

This part applies to the products we give away: the DX22OP console, both the Windows download and the installable web app; the CX22OP amateur radio console; and any hosted demonstration workspace we make publicly available, including the seeded Tessera RP demo.

You get a personal, worldwide, royalty-free, non-exclusive, non-transferable licence to install and use them, for any purpose including commercial ones, for as long as these terms stand. No account, no registration, no fee.

What the licence does not include: reselling them, distributing modified builds, removing or altering attribution, or reverse engineering except to the extent that Indian law says you may regardless of what a licence says. The software remains ours; you are licensed, not sold.

These products are provided as is and as available, without warranty of any kind, express or implied, including any implied warranty of merchantability, fitness for a particular purpose, accuracy or non-infringement. To the fullest extent permitted by law, we disclaim all of them.

We do not promise that they are free of defects, that they will run on your hardware, that they will keep working after an operating system update, or that we will continue to publish them. There is no support commitment and no service level. We do fix things, and we would like to hear about a bug, but that is goodwill rather than an obligation.

Verify the Windows installer before you run it. Its SHA-256 hash is published on the product page, and checking it is the only way to know that what you downloaded is what we published.

DX22OP computes astronomical positions, panchang elements and traditional Vedic calendar interpretations. The astronomical arithmetic is genuine and testable. The interpretive material is a presentation of a traditional system, offered for interest and reference. It is not medical, psychological, financial, legal or any other kind of professional advice, and no decision with real consequences should rest on it.

CX22OP is a reference and logging console for amateur radio operators. It does not confer, replace or evidence any licence. Transmitting requires the appropriate authorisation from your national authority — in India, the Wireless Planning and Coordination wing of the Department of Telecommunications — and operating within your licence conditions and band plan is your responsibility, not the software's. Band and frequency information is published for reference and the authority's own publication governs.

Lawlipop and any other legal-domain product we publish produce drafting and research assistance. They are not a lawyer and their output is not legal advice.

DX22OP and CX22OP compute on your device and keep what you enter on your device. We do not receive your birth data, your location, your journal entries or your log. There is no account because there is nothing for an account to hold, and there is no analytics in either product.

That also means the data is yours to look after. We cannot recover it, because we never had it. Use the product's own export if it matters to you.

The hosted demonstrations are different and should be treated as public. The seeded Tessera RP workspace has no password, is shared with everyone who opens it, and is periodically reset. Do not put anything real, confidential or personal into it.

Nothing on this site is an offer capable of acceptance. Descriptions of capabilities, programmes, timelines or indicative pricing are information, not a quotation, and sending a brief through the contact form or the assistant does not create an engagement or any obligation on either side.

Work begins when both sides sign something: a proposal, a statement of work, or a master services agreement with a work order under it. That document sets the scope, the deliverables, the fees, the timeline and the acceptance criteria.

Where that document and this page disagree, that document wins. This part exists to describe how we work and to fill gaps, not to override a negotiated contract.

Our default, absent anything different in the signed document: on full payment, the deliverables specifically created for you are assigned to you, and you own them outright.

Three things are carved out of that, and they are carved out in every engagement. We keep ownership of anything that existed before the engagement — our libraries, frameworks, internal tooling and prior work — and you get a perpetual licence to use it inside the deliverable. We keep ownership of general skill, know-how and technique acquired while doing the work, which is not capable of being assigned in any useful sense. And third-party components stay with their own licensors under their own licences, which we identify to you.

Our in-house products are not deliverables. Where an engagement uses Tessera DB, Tessera RP, Tessera Viz or another of our products, it is licensed to you on its own terms and does not transfer.

Fees, currency, taxes, invoicing schedule and payment terms are set in the signed document. Indian goods and services tax is charged where applicable and is additional to quoted fees unless the document says a figure is inclusive.

Scope changes are priced and agreed in writing before they are built. This is not administrative fussiness — an unpriced change is the single most reliable way for a project to end badly, and we would rather have the awkward conversation early.

Each side keeps the other's confidential information confidential, uses it only for the engagement, and returns or destroys it on request. That obligation survives the engagement. Where personal data is involved, a data processing agreement sits alongside the contract and the roles are set out in it.

We may describe the general nature of the work publicly — a Mission entry on this site, for example — only with your written agreement, and never using anything you marked confidential.

We warrant that the services will be performed with reasonable skill and care by people competent to perform them, and that the deliverables will conform in material respects to the specification agreed in the signed document for the warranty period stated there.

Our remedy for a breach of that warranty is to fix it: to re-perform the work or correct the deliverable within a reasonable time. That is the remedy we commit to, and beyond it we make no other warranty, express or implied, about the services.

We do not warrant uninterrupted or error-free operation of anything, and we are not responsible for a failure caused by your infrastructure, your data, a third-party service, or a change you or somebody else made to what we delivered.

Nothing here limits liability that cannot lawfully be limited — death or personal injury caused by negligence, fraud or fraudulent misrepresentation, or any other liability Indian law does not permit us to exclude.

Subject to that, and to the fullest extent permitted by law, neither side is liable to the other for indirect or consequential loss, loss of profit, loss of revenue, loss of anticipated savings, loss of business or loss of goodwill, however arising.

For the website and the free products, our total aggregate liability to you is limited to five thousand rupees. They are given away and no fee has changed hands, which is the whole basis on which they are offered.

For paid work, our total aggregate liability is limited to the fees paid by you under the relevant statement of work in the twelve months before the claim arose, unless the signed document sets a different figure — in which case that figure applies.

You will indemnify us against claims, losses and reasonable costs arising from your use of the site or the free products in breach of these terms, from content you submit to us, or from your infringement of somebody else's rights.

In an engagement, the indemnities that apply are the ones in the signed document, which are mutual and negotiated. This clause does not displace them.

If any provision here is held unenforceable, it is severed and the rest stands. A failure to enforce a right is not a waiver of it. These terms, together with the privacy policy and any signed engagement document, are the whole agreement between us on their subject matter, and replace anything said before.

You may not assign your rights under these terms without our written consent. We may assign ours as part of a transfer of the business.

Neither side is liable for a failure caused by something genuinely outside its reasonable control, provided it says so promptly and works to resolve it.

These terms, and any dispute arising out of or in connection with them or their subject matter, are governed by the laws of India, without regard to conflict of laws rules.

The courts at Hyderabad, Telangana have exclusive jurisdiction, and both sides submit to it. Before either side files anything, both agree to spend thirty days genuinely trying to resolve the matter between senior people — which is usually faster, cheaper and better for the relationship than the alternative.

Where a signed engagement document specifies a different governing law, forum or dispute procedure, that document governs for that engagement.
