QEMICA END USER LICENSE AGREEMENT (EULA)
Version 2026-07-22
This End User License Agreement ("Agreement") is a contract between you
("you", "User") and Qemica Lab, an independent software developer based
in the Republic of Korea, reachable at feedback.qemica@gmail.com ("we",
"Operator"), governing your use of the Qemica desktop application and
the separately downloaded Qemica computation engine (a Python component
installed at your direction; together, the "Software").
By clicking "Agree and continue", installing, or using the Software, you
accept this Agreement. If you do not accept it, do not use the Software.
1. LICENSE GRANT
We grant you a personal, non-exclusive, non-transferable, revocable
license to install and use the Software on devices you control, in
object/executable form, subject to this Agreement and your active
plan (Section 4).
2. OWNERSHIP
The Software is licensed, not sold. We and our licensors retain all
rights not expressly granted. Your molecules, inputs, and calculation
results are YOURS (Section 5).
3. RESTRICTIONS
You may not, except to the extent permitted by applicable law or by
the open-source licenses referenced in Section 7:
a. redistribute, sell, rent, sublicense, or host the Software for
third parties;
b. reverse engineer, decompile, or disassemble the proprietary parts
of the Software;
c. circumvent plan gating, license checks, or usage limits;
d. use the Software to build a competing hosted service.
4. PLANS
a. FREE PLAN. Core modeling, calculation, and analysis features at
no charge. In exchange, the Free plan includes your consent to
calculation contributions as described in Section 5(b) and in the
Privacy Policy. Contribution collection is not yet active; the
Software will tell you before it begins.
b. PREMIUM PLAN (not yet available for purchase). A paid
subscription that will include everything in Free, plus: private
results (no calculation contribution) and early access to
pre-release versions. Prices, terms, and renewal will be shown at
purchase.
c. EARLY-ACCESS BUILDS are pre-release software, provided AS IS,
may be unstable, and may change or remove features.
5. YOUR CONTENT AND CALCULATION CONTRIBUTIONS
a. You retain all rights to structures you create or import and to
the calculation results the Software produces for you.
b. FREE PLAN CONTRIBUTIONS. Contribution collection is not yet
active: today, no calculation data leaves your machine. Once it
is active, on the Free plan the Software will collect calculation
contributions: the input structure, calculation settings,
computed results, and engine provenance (versions, timings),
together with the app version. Contributions will be severed from
your account identity at ingestion. User-assigned names, notes,
file paths, and personal identifiers will NOT be collected. You
grant us a non-exclusive, worldwide, royalty-free, perpetual and
irrevocable license to use such contributions to evaluate,
benchmark, and improve calculation methodology and the Software,
and to train, fine-tune, and validate machine-learning models
(including models we may make available in or outside the
Software). The license is perpetual and irrevocable only as to
contributions already collected before you withdraw consent or
change plans; see Section 6 of the Privacy Policy for how to stop
future collection.
c. WE WILL NOT sell calculation contributions to third parties or
use them for advertising.
d. PREMIUM PLAN data is not collected under (b). Your projects and
results remain on your devices; the Software does not upload them
to us. The Software can export your data as a local archive file
that you may move between your devices yourself.
6. ACCOUNTS
Some features require an account (Section 2 of the Privacy Policy).
You are responsible for safeguarding your credentials.
7. OPEN-SOURCE COMPONENTS
The Software includes open-source components (e.g. Godot Engine,
RDKit, PySCF, geomeTRIC). Each is governed by its own license, which
is included with the Software (THIRD-PARTY notices). Nothing in this
Agreement restricts rights those licenses grant you. Optional
components you install separately (e.g. OpenBabel, GPL-2.0) are
governed solely by their own licenses.
8. SCIENTIFIC DISCLAIMER
The Software produces COMPUTATIONAL PREDICTIONS. Results depend on
method, basis, and settings, and may be inaccurate or unsuitable for
your purpose. THE SOFTWARE IS NOT A SUBSTITUTE FOR EXPERIMENTAL
VALIDATION OR PROFESSIONAL JUDGMENT. Do not rely on results for
clinical, safety-critical, or regulatory decisions without
independent verification.
9. THIRD-PARTY SERVICES AND API COSTS
The Software can optionally connect to third-party services — IBM
Quantum (cloud quantum hardware), the Anthropic Claude API (the
in-app research assistant), and remote SSH/HPC systems, each using
credentials you supply, and the public PubChem database (no account
needed). Your use of any such service is
governed solely by your agreement with that provider. YOU ARE
RESPONSIBLE FOR ALL FEES, USAGE CHARGES, AND QUOTAS THAT SUCH
PROVIDERS BILL for requests the Software makes with your
credentials, whether or not the requests succeed or produce useful
results. We are not a party to those agreements, do not resell those
services, and are not liable for their pricing, availability,
output, or any costs you incur through them.
10. UPDATES
The Software can check for updates at launch, but only if you turn
that on — it is off unless you ask for it, and you can change your
answer at any time in the app's settings. Updates are never
downloaded or installed silently; you choose whether to install
them.
11. TERMINATION
This Agreement ends automatically if you materially breach it. You
may end it by deleting the Software. Sections 2, 5, 8, 9, 12, 13,
and 14 survive termination. Your local files remain yours and
readable (open formats: project folders, .xyz/.mol, result.json).
12. WARRANTY DISCLAIMER
THE SOFTWARE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND,
EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A
PARTICULAR PURPOSE, ACCURACY, AND NON-INFRINGEMENT, TO THE MAXIMUM
EXTENT PERMITTED BY LAW.
13. LIMITATION OF LIABILITY
TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE ARE NOT LIABLE FOR
INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES,
OR LOSS OF DATA, PROFITS, OR RESEARCH RESULTS. OUR TOTAL LIABILITY
IS LIMITED TO THE AMOUNT YOU PAID FOR THE SOFTWARE IN THE 12 MONTHS
BEFORE THE CLAIM (OR USD 10 IF YOU PAID NOTHING).
NOTHING IN THIS AGREEMENT EXCLUDES OR LIMITS LIABILITY THAT CANNOT
LAWFULLY BE EXCLUDED OR LIMITED. This includes liability for death or
personal injury caused by negligence, for fraud or fraudulent
misrepresentation, and for intent or gross negligence. If you are a
consumer, the mandatory consumer-protection law of your country of
residence applies to you regardless of anything in Sections 12 to 14
— including, where applicable, the Republic of Korea's consumer
protection and standard-terms legislation and EU/EEA consumer law —
and the disclaimers and limits above apply only to the extent that
law permits.
14. GOVERNING LAW AND DISPUTES
This Agreement is governed by the laws of the Republic of Korea,
without regard to conflict-of-law rules, and disputes arising out of
or in connection with it shall be submitted to the Seoul Central
District Court as the court of first instance.
IF YOU ARE A CONSUMER, this does not deprive you of the protection
of the mandatory law of the country where you live: you keep any
right you have under that law to bring proceedings in, and to have
your claim decided under the law of, your own country of residence.
We may bring proceedings against a consumer only in the courts of
the country where that consumer lives.
Nothing above prevents either party from seeking urgent injunctive
relief in any court of competent jurisdiction.
15. CHANGES TO THIS AGREEMENT
We may update this Agreement. Material changes are presented in the
app for re-acceptance before they apply to you; the version date at
the top identifies the text you accepted.
