End User License Agreement
1. Acceptance of these terms
This End User License Agreement (“Agreement”) is a binding agreement between you (“you,” “your,” or “User”) and LureSight LLC governing your use of the LureSight software, including the Outlook add-in, the web-based email scanner, the community service and public dashboard, and any related documentation and updates (together, the “Software”). By installing, accessing, or using the Software, you agree to this Agreement and to the LureSight Privacy Policy, which is incorporated by reference. If you do not agree, do not install or use the Software.
If you use the Software on behalf of an organization, you represent that you have authority to bind that organization, and “you” includes that organization.
2. What LureSight is — and what it is not
LureSight is assistive technology. It applies heuristic checks and an optional community-trained model to help a person notice signs that an email may be a phishing or social-engineering attempt, and to explain those signs in plain language. It is a decision aid that supports human judgment.
LureSight is not a security guarantee, a spam filter, an antivirus product, or a substitute for your own judgment or your organization's security controls. It does not open, block, quarantine, or remove messages, and it does not protect any system from compromise.
Please understand these limits before relying on the Software
It will miss things. The Software cannot detect all phishing, malware, fraud, or malicious content. A result of “no obvious flags,” a low score, or the absence of any warning means only that the Software did not find evidence — it does not mean a message is safe, legitimate, or free of threats.
It will sometimes be wrong. The Software may flag legitimate messages (false positives) and may fail to flag harmful ones (false negatives). Scores and verdicts are estimates, not determinations of fact.
You remain responsible. You are solely responsible for how you act on the Software's output, including whether you open links or attachments, disclose information, transfer funds, or report or delete a message. Always apply independent judgment and follow your organization's security policies.
3. License grant
Subject to your continuous compliance with this Agreement, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use the Software for your own internal or personal purposes of assessing email for potential phishing indicators.
4. License restrictions
Except as expressly permitted by this Agreement, by the applicable open-source licenses described in Section 8, or by mandatory law, you will not:
copy, modify, or create derivative works of the Software except as its license terms allow;
sell, rent, lease, sublicense, distribute, or provide the Software as a commercial service to third parties without our prior written consent;
remove, obscure, or alter any proprietary notices, or misrepresent the origin of the Software;
use the Software to build a competing product by improper means, or reverse engineer it except to the extent this restriction is prohibited by law or permitted by an open-source component's license;
use the Software unlawfully, to infringe others' rights, or to process content you have no right to process; or
rely on the Software as a sole or primary control where its failure could cause injury, financial loss, or other serious harm.
5. Reporting and community features
Report to security. The Software can help you send a suspected message to a reporting address that you or your organization configure. That message goes to the address you choose; we do not receive it.
Community submissions are optional and off by default. If you choose to submit a report to the LureSight community service, an anonymized, personal-information-scrubbed record is sent as described in the Privacy Policy. You must not submit content you are not permitted to share. Submissions are voluntary, are used to improve detection and to produce aggregate threat statistics, and are governed by the Privacy Policy.
6. Local processing
The web-based scanner and the optical-character-recognition (OCR) step run in your browser or on your device. Files you scan there are processed locally and are not transmitted to us by the Software as part of the scan. Details are in the Privacy Policy.
7. Third-party and open-source components
The Software includes third-party open-source components, which may include, without limitation, DOMPurify, Tesseract.js, Chart.js, and the Node.js runtime. Those components are licensed under their own terms (e.g. MIT, Apache 2.0), which govern your use of them and, in case of conflict, control over this Agreement with respect to those components. Attributions and license texts are available on request or in the Software's distribution. Third-party components are provided by their respective authors without warranty.
8. Ownership and intellectual property
As between you and us, we and our licensors retain all right, title, and interest in and to the Software, excluding third-party components and your own content. No rights are granted except as expressly stated. You may provide feedback, and you grant us a perpetual, royalty-free license to use feedback without obligation to you.
9. Updates and changes
We may update, modify, suspend, or discontinue the Software or any feature at any time, including detection rules and models, and we may revise this Agreement. Material changes take effect when we post the updated Agreement or as otherwise required by law; your continued use after changes take effect constitutes acceptance. We are not obligated to provide support, maintenance, or updates.
10. Disclaimer of warranties
THE SOFTWARE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE AND OUR LICENSORS DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE.
WITHOUT LIMITING THE FOREGOING, WE DO NOT WARRANT THAT THE SOFTWARE WILL DETECT ANY OR ALL PHISHING OR MALICIOUS CONTENT, THAT ITS RESULTS WILL BE ACCURATE, COMPLETE, OR RELIABLE, THAT IT WILL BE UNINTERRUPTED, TIMELY, SECURE, OR ERROR-FREE, OR THAT DEFECTS WILL BE CORRECTED. NO ADVICE OR INFORMATION, WHETHER ORAL OR WRITTEN, CREATES ANY WARRANTY.
Some jurisdictions do not allow the exclusion of certain warranties, so some exclusions above may not apply to you; in that case, such warranties are limited to the minimum scope and duration permitted by law.
11. Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE AND OUR LICENSORS AND SUPPLIERS WILL HAVE NO LIABILITY FOR, AND YOU ASSUME ALL RISK ARISING FROM, YOUR USE OF OR RELIANCE ON THE SOFTWARE AND ITS OUTPUT — including any phishing, fraud, malware, account compromise, data loss or breach, financial loss, business interruption, or other harm that the Software fails to prevent, detect, or warn about, or that results from a false positive or false negative.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL WE OR OUR LICENSORS OR SUPPLIERS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS, ARISING OUT OF OR RELATED TO THE SOFTWARE OR THIS AGREEMENT, UNDER ANY THEORY OF LIABILITY, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THE SOFTWARE OR THIS AGREEMENT WILL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID US FOR THE SOFTWARE IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) US $100. IF YOU OBTAINED THE SOFTWARE AT NO CHARGE, ITEM (A) IS ZERO.
These limitations apply to the fullest extent permitted by law. Some jurisdictions do not allow certain limitations, so parts of this section may not apply to you. Nothing in this Agreement excludes or limits liability that cannot lawfully be excluded or limited (for example, for death or personal injury caused by negligence, or for fraud).
12. Indemnification
To the extent permitted by law, you will defend, indemnify, and hold harmless LureSight LLC and its officers, employees, and agents from and against any claims, damages, liabilities, and expenses (including reasonable legal fees) arising out of your use of the Software in violation of this Agreement or applicable law, or your submission of content you had no right to submit.
13. Term and termination
This Agreement applies while you use the Software. It terminates automatically if you breach it, and we may suspend or terminate your license at any time. On termination, you must stop using and remove the Software. Sections that by their nature should survive — including ownership, disclaimers, limitation of liability, indemnification, and governing law — survive termination.
14. Governing law and disputes
This Agreement is governed by the laws of the Commonwealth of Pennsylvania, USA, without regard to conflict-of-laws rules. The courts located in the Commonwealth of Pennsylvania, USA will have exclusive jurisdiction, except that either party may seek injunctive relief in any competent court. Mandatory consumer-protection rights in your place of residence are unaffected.
15. Export and lawful use
You will comply with all applicable export-control and sanctions laws and will not use the Software where prohibited by law.
16. General
Entire agreement. This Agreement and the Privacy Policy are the entire agreement between you and us regarding the Software and supersede prior understandings. Severability. If any provision is held unenforceable, the rest remains in effect and the provision is modified to the minimum extent necessary. No waiver. Our failure to enforce a provision is not a waiver. Assignment. You may not assign this Agreement without our consent; we may assign it in connection with a merger, acquisition, or sale of assets. No third-party beneficiaries, except our licensors as intended beneficiaries of the disclaimers and liability limits.
