End-User License Agreement

This Agreement sets forth the terms and conditions of your use of Sonomos Locke — the local daemon, the graphical desktop application, the command-line tools, and any related installers, updates, or documentation (collectively, the "Software"). "You" or "End-User" means you, the individual or entity installing or using the Software, and "Licensor" means Sonomos, Inc., a Delaware corporation with its principal place of business at 9924 Kika Court #2416, San Diego, CA 92129.

The Software is a desktop application distributed directly by Licensor for download at sonomos.ai and Licensor's designated release channels, for Windows and Linux, with macOS support planned. The Software is proprietary and closed-source; this Agreement grants You a license to use it, not the underlying code.

Account — The user account You create to access and manage Your use of the Software and related Services.

Authorized Device — A desktop or laptop computer that You own or control, running Windows or Linux (macOS planned) and meeting the technical requirements in the Documentation.

Confidential Information — Any non-public information disclosed by either party to the other, whether orally or in writing, that is designated as confidential or that reasonably should be understood to be confidential.

Documentation — The user guides, help files, technical specifications, and other documentation made available by Licensor at sonomos.ai/docs or through the Software.

License Fees — The subscription fees or other amounts payable by You to Licensor for the right to use the Software.

Local Processing — The detection, analysis, masking, encryption, or other processing of data that occurs entirely on Your Authorized Device, without transmitting the data being processed to Licensor's servers, any third-party server, or any external service.

Order Form — Any ordering document, online subscription form, or enterprise agreement executed between You and Licensor that references this Agreement.

Services — The web-based account management, license validation, subscription management, and related services provided by Licensor in connection with the Software.

Software — The Sonomos Locke desktop application in object-code (binary) form, including the local daemon, the graphical application, the command-line interface, any Updates, and the Documentation. Also referred to in this Agreement, and in Licensor's marketing, as "Locke."

Subscription Term — The period during which You are authorized to use the Software, as specified in Your subscription plan or Order Form, including any renewal periods.

Update — Any update, upgrade, patch, hotfix, or new version of the Software that Licensor makes generally available to its licensees.

2.1 The Software is a desktop application designed to add a system-wide, on-device privacy layer across the AI tools You use — including browser-based chat interfaces, native AI applications, IDE assistants, and local models — before sensitive information reaches them. The Software provides:

• real-time, local-only detection of sensitive data in Your inputs, with clear indicators of what was found;
• on-device masking of sensitive data using pattern matching and machine-learning models, using reversible encryption to obfuscate the data before it is transmitted, and restoring it in the response; and
• configurable privacy preferences, real-time alerts, and controls to help You make informed decisions about sharing information with AI tools and online services.

2.2 Local-First Architecture. All sensitive data detection, encryption, and masking performed by the Software occurs entirely on Your Authorized Device through Local Processing. The Software does not transmit, upload, store, or provide Licensor access to any content You type, paste, scan, or process.

2.3 No Guarantee of Complete Protection. The Software operates as a user-side privacy assistance tool. Licensor does not guarantee that the Software will detect all sensitive data, prevent all disclosures, or operate without interruption or error.

2.4 Use in Regulated Environments. The Software may be used as part of a broader privacy and compliance program. However, use of the Software alone does not constitute compliance with any specific regulation, including but not limited to HIPAA, GLBA, FISMA, or similar frameworks.

3.1 Subject to the terms of this Agreement and payment of all applicable License Fees, Licensor hereby grants to You a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use the Software on Authorized Devices that You own or control, solely in accordance with this Agreement, the Documentation, and applicable law.

3.2 This license shall govern any Updates to the Software provided by Licensor that replace, repair, or supplement the Software, unless a separate license is provided for such Update.

3.3 Licensor reserves all rights in the Software not expressly granted to You under this Agreement.

3.4 For enterprise or team subscriptions, the license grant extends to the number of authorized users specified in the applicable Order Form. Each authorized user must have a unique Account.

4.1 You agree that You shall not:

1. share, sublicense, sell, rent, lend, lease, distribute, or otherwise make the Software available to any third party;
2. reverse engineer, translate, disassemble, decompile, decrypt, or otherwise attempt to derive the source code, except to the extent expressly prohibited by applicable law;
3. copy, modify, adapt, create derivative works or updates of, or integrate the Software with any other software, except as expressly authorized;
4. remove, alter, obscure, or deface any copyright notices, trademarks, or other proprietary rights notices;
5. use the Software for purposes of competitive analysis, benchmarking, or developing a competing product;
6. use the Software to engage in any activity that violates applicable law, including facilitating concealment of information in violation of legal discovery or reporting obligations;
7. circumvent, disable, or interfere with any security, authentication, or license management features;
8. use the Software on behalf of any unauthorized third party; or
9. use automated means, including scripts, bots, or scrapers, to interact with or extract data from the Software.

4.2 You may create and store backup copies of the Software only on Authorized Devices that You own or control. If You transfer ownership of an Authorized Device, You must remove the Software before doing so.

4.3 Violations of this Section 4 may result in immediate termination of this Agreement and may subject You to prosecution, damages, and injunctive relief.

5.1 Local Processing. The Software processes all user content exclusively through Local Processing on Your Authorized Device. No user content is transmitted to Licensor's servers, any third-party server, or any external service at any time during the detection, analysis, masking, or encryption process.

5.2 Server Communications. The Software communicates with Licensor's servers solely for: (a) license validation and subscription status verification; (b) delivery of Updates through Licensor's designated update channel; and (c) account authentication through Your designated authentication provider.

5.3 No Telemetry or Tracking. The Software does not collect telemetry, usage analytics, crash reports, browsing history, or interaction data, and does not use cookies, tracking pixels, or similar tracking mechanisms.

5.4 Outbound Connections. Aside from the connections described in Section 5.2, the only network connections the Software initiates on its own behalf are (a) optional update checks and (b) standard TLS certificate-revocation checks. Any request You send to an AI provider through the Software is relayed to that provider at Your direction; Licensor is not the recipient of that request.

5.5 Privacy Policy. Licensor's collection and use of personal information is governed by the Privacy Policy at sonomos.ai/privacy.

6.1 Access to certain features requires payment of License Fees. Licensor may offer a Free Tier with limited functionality and one or more paid subscription tiers.

6.2 License Fees are billed in advance on a recurring basis (monthly or annually) through Stripe, Inc. All License Fees are non-refundable except as expressly provided herein or as required by applicable law.

6.3 Licensor may modify License Fees upon thirty (30) days' prior written notice. Modified fees take effect at the start of Your next Subscription Term.

6.4 If You fail to pay License Fees when due, Licensor may suspend or terminate access upon ten (10) days' written notice.

7.1 This is a license agreement, not an agreement for sale. Licensor retains all right, title, and interest in and to the Software and Documentation.

7.2 The Software and Documentation are protected by United States and international copyright laws and international treaty provisions.

7.3 Feedback. If You provide suggestions, ideas, or feedback, You grant Licensor a perpetual, irrevocable, worldwide, royalty-free license to use, reproduce, modify, and exploit such Feedback.

7.4 Your Content. Licensor does not acquire any right, title, or interest in any content You process using the Software. Because all content processing occurs through Local Processing, Licensor never receives, accesses, or stores Your content.

8.1 You are responsible for ensuring that Your Authorized Device and operating system (Windows or Linux; macOS planned) meet the technical requirements in the Documentation.

8.2 Licensor may attempt to keep the Software compatible with updated environments; however, Licensor does not guarantee the availability of Updates.

8.3 Licensor may modify technical specifications or supported environments at any time with commercially reasonable advance notice.

9.1 Licensor is solely responsible for maintenance and support. Contact: sonomos.ai/contact.

9.2 Support availability and response times may vary by subscription tier.

9.3 No third-party distributor has any obligation to furnish maintenance or support for the Software.

Licensor warrants that: (a) the Software is free of known malware at the time of download; (b) the Software will perform substantially in accordance with the Documentation for ninety (90) days from initial download; and (c) the Software is designed to perform all sensitive data processing through Local Processing on Your Authorized Device.

Licensor's sole remedy for breach of this warranty shall be, in Licensor's discretion: repair or replacement; advice on achieving substantially the same functionality; or a refund of License Fees for the then-current Subscription Term.

The Software is a technical tool and is not a substitute for legal advice or a qualified compliance program, and is not designed or intended for use in situations requiring fail-safe performance, such as life-support systems, medical devices operating in a clinical capacity, or other safety-critical infrastructure.

You agree to defend, indemnify, and hold harmless Licensor from and against all liabilities, losses, costs, damages, and expenses arising from third-party claims relating to: (a) Your use of the Software in violation of this Agreement; (b) Your violation of applicable law; (c) Your negligent or wrongful acts; or (d) any content You process using the Software.

14.1 Term. This Agreement is effective from first install or use and continues for the Subscription Term, including renewals, unless earlier terminated.

14.2 Automatic Renewal. Your subscription automatically renews for successive periods of the same duration at then-current fees unless canceled before the current term ends.

14.3 Termination by You. You may terminate at any time by canceling Your subscription, uninstalling and deleting all instances, and destroying all copies in Your possession.

14.4 Termination by Licensor. Licensor may terminate immediately if You: breach any material term; fail to pay fees after ten (10) days' notice; file for bankruptcy; or engage in activity causing harm to Licensor or other users.

14.5 Termination for Convenience. Either party may terminate upon thirty (30) days' written notice. If Licensor terminates for convenience, Licensor will refund the pro-rata portion of prepaid License Fees.

Upon termination, You shall immediately cease all use, uninstall and delete all instances, and destroy all copies. No refund of License Fees upon termination for cause, except as provided in Section 14.5.

Survival. Sections 1, 5.1, 7, 11, 12, 13, 15, 19, and 21 survive termination.

You represent and warrant that You are not in an embargoed country or on any U.S. Government prohibited parties list. You will not import or export the Software in violation of applicable law.

The Software incorporates certain third-party open-source software components. The identity, version, and license of each open-source component as distributed with each release is listed in the file THIRD-PARTY-LICENSES.md shipped with the Software and accessible from the Software's About screen.

Open-source components are licensed to You under their respective open-source licenses, not under this Agreement. Where a component is licensed under a copyleft license such as the Mozilla Public License, Your rights with respect to the source files of that component are preserved under that license, and Licensor makes the corresponding source available as required. Nothing in this Section requires Licensor to disclose or license any other portion of the Software under an open-source license.

This Agreement is for the benefit of the parties only. No third party is an intended or incidental beneficiary of this Agreement.

This Agreement shall be governed by the laws of the State of California, without regard to conflict of laws provisions. You consent to the exclusive jurisdiction of the federal and state courts in San Diego County, California.

Licensor shall not be liable for any failure or delay in performance due to causes beyond its reasonable control, including labor disputes, war, fires, floods, governmental regulations, public health orders, pandemics, cyberattacks, internet or telecommunications failures, or acts of God.

21.1 Entire Agreement. This Agreement, together with the Privacy Policy and any applicable Order Form, constitutes the complete and exclusive agreement between the parties.

21.2 Amendments. Licensor may update this Agreement with at least thirty (30) days' prior written notice. Continued use constitutes acceptance.

21.3 Severability. If any provision is found invalid, the remaining provisions remain in full force and effect.

21.4 No Assignment. You may not assign this Agreement without Licensor's prior written consent.

21.5 No Waiver. Failure or delay by Licensor to require performance does not constitute a waiver.

21.6 Notices. All notices shall be in writing and deemed given when delivered personally, sent by confirmed email, or sent by certified mail.

21.7 Headings. Section headings are for convenience only.

21.8 Acknowledgment. By downloading, installing, or using the Software, You indicate that You have read, understood, and agree to be bound by this Agreement.
