Legal
These terms apply to Lavender products purchased directly on this website. Lavender Desk and Lavender Enterprise are provided under a separate signed agreement.
Last updated: Version 2 · 26 October 2026
This User Agreement (the "Agreement") is a legal contract between you ("you," "User") and Lavender Trading Solutions LLC, a Wyoming limited liability company ("Lavender," "we," "us," "our").
What this Agreement covers. This Agreement governs the Lavender products available for purchase through self-service checkout at lavender-ts.com, together with the websites, applications, software, REST APIs, desktop applications, Discord bots and integrations, dashboards, tools, content, and documentation provided as part of them (collectively, the "Services"). The Services are:
What this Agreement does not cover. Lavender offers other editions that are provided only under a separate written agreement executed between you and Lavender, and that are not available through self-service checkout. These include Lavender Desk and Lavender Enterprise. They are not Services under this Agreement.
If you have executed a separate written agreement with Lavender covering any product, edition, or deployment, that agreement governs your use of it and this Agreement does not apply to it. Where an executed agreement and this Agreement address the same subject matter, the executed agreement controls. Nothing in this Agreement grants any right or license in respect of any Lavender product or edition not listed as a Service above, and no description of another edition in this Agreement or on our website creates one.
Acceptance. By completing self-service checkout, clicking "I agree," or downloading, installing, accessing, or using any of the Services, you agree to be bound by this Agreement. If you do not agree to this Agreement in its entirety, do not purchase, download, access, or use the Services. Downloading, installing, or using a product that Lavender has furnished to you under a separate written agreement is not an acceptance of this Agreement, and this Agreement imposes no obligations on you in respect of that product.
You represent and warrant that you are at least 18 years old (or the age of majority in your jurisdiction, whichever is greater), that you have full legal capacity to enter into this Agreement, and that your use of the Services does not violate any applicable law or regulation.
You are responsible for:
You may not share your subscription access, credentials, or locally-running Gateway instance with individuals outside your permitted user count as specified in your subscription plan.
Authority to Bind. If you accept this Agreement on behalf of an organization, company, fund, or other entity, you represent and warrant that you have the legal authority to bind that entity and all of its Authorized Users to this Agreement. In that case, "you" and "User" refer to that entity and its Authorized Users, and the entity is responsible for ensuring all such persons comply with this Agreement.
Authorized Users. "Authorized Users" means the individuals the subscriber permits to access and use the Services within the user/seat count specified in the subscriber's subscription plan. The subscriber's acceptance of this Agreement binds the subscriber and each of its Authorized Users, and the subscriber is responsible for each Authorized User's compliance with this Agreement, including any act or omission by an Authorized User that would constitute a breach if done by the subscriber.
Lavender provides independently computed options analytics software. The Services are designed to help users analyze option Greeks, implied volatility, and related risk metrics across the OPRA options universe.
Lavender Gateway runs locally on your machine at localhost:2112. It computes and delivers option Greeks and implied volatility via REST API. It is not a market data service — it does not deliver bid/ask prices, volume, open interest, or trade data. Market data fields present in vendor-compatible API responses are included for wire compatibility only and are zeroed or null.
Lavender Terminal is a desktop application for visualizing options chains, risk metrics, scenario analysis, and volatility analytics. It is powered by the same analytics engine as Gateway. Terminal may connect to a supported brokerage account on a read-only basis in order to read positions; it does not write to that account. Any trade you enter in Terminal is directed to a paper-trading account. Terminal does not place, route, transmit, or execute orders to a live account, to a broker, or to any market or execution venue.
Lavender Discord delivers volatility observations, IV/RV commentary, and market structure analysis through a Discord community.
Other editions. Lavender Desk and Lavender Enterprise are described at lavender-ts.com but are not provided under this Agreement. Their capabilities differ from the Services described in this Section — including, for Lavender Desk, optional order routing to a client's own executing broker — and are governed solely by the separate written agreement covering them.
The Services may integrate with or depend on third-party data sources, including market data vendors, and may depend on third-party platforms including Discord. The availability and quality of certain features may depend on your own third-party data subscriptions and vendor relationships, which are governed by your separate agreements with those vendors.
Lavender is not a broker-dealer, investment adviser, commodity trading advisor, financial planner, or registered financial institution of any kind. The Services are provided for informational and analytical purposes only and do not constitute financial services of any kind.
No order handling. The Services do not place, route, transmit, or execute orders, and are not built to do so. With respect to the Services, Lavender is not an executing broker, introducing broker, clearing firm, order management system, or execution management system. Where you connect a brokerage account to the Services, that connection is read-only. You are solely responsible for entering, transmitting, and managing any live order with your own broker, through your own relationship with that broker.
Nothing in the Services, including any analytics, outputs, Greeks calculations, implied volatility estimates, commentary, or observations, constitutes:
You acknowledge and agree that:
Trading securities and derivatives, including options, involves substantial risk of loss and is not appropriate for all investors. Options trading involves unique risks including leverage, time decay, volatility exposure, and the potential for rapid and total loss of invested capital. In certain strategies, losses may exceed your initial investment.
You understand, acknowledge, and agree that:
This risk disclosure does not purport to disclose all risks associated with options trading. You should carefully consider your financial situation and consult appropriate professional advisors before trading options.
The Services include quantitative outputs, model estimates, implied values, Greeks calculations, and analytics. These outputs are inherently dependent on assumptions, inputs, and models that may be imperfect, and they are not a substitute for independent professional analysis.
To the fullest extent permitted by applicable law:
Some jurisdictions do not allow the exclusion of implied warranties, so some of the above exclusions may not apply to you.
The Services run locally on your machine, and they communicate with Lavender's servers over HTTPS in the course of operating. In connection with the Services, Lavender receives: (a) the email address and subscription key associated with your account, for authentication and entitlement; (b) the contract identifiers you request analytics for — underlying symbol, strike, and expiration date, and not the quantity or size of any position you hold; and (c) usage telemetry describing your use of the Services, such as which features and commands are invoked and how often.
Lavender does not require, and the Services are not designed to transmit, your broker credentials or your market data vendor credentials.
The help documentation for each Service describes what that Service sends in further detail. Where the documentation and this Section differ, this Section governs.
This Section describes the Services covered by this Agreement. Other Lavender editions may operate differently, and the handling of data in those editions is governed by the separate written agreement covering them.
You are responsible for the security of your local machine, network environment, and any credentials configured for use with the Services. Lavender is not responsible for unauthorized access to your local installation or data resulting from your failure to maintain adequate security controls.
We want the Services to be valuable, stable, and reliable for all users. You agree to use the Services in a reasonable and lawful manner.
7.1 Prohibited Conduct. You will not, and will not permit or enable others to:
7.2 Fair Use Limits. We may implement fair-use limits including rate limits on API queries, commands, chart generation, or other requests; daily or monthly usage caps by subscription tier; and restrictions by user, device, or access token. If your usage materially exceeds typical patterns for your subscription tier, including high-frequency automated querying, we may throttle, suspend, or require you to upgrade to an appropriate plan. We may modify fair-use limits at any time to protect service stability and to comply with vendor obligations, with reasonable notice where practicable.
8.1 Subscription Plans and Pricing. Current subscription plans and pricing are described at lavender-ts.com. Subscriptions are offered on a month-to-month basis unless otherwise stated. We reserve the right to change pricing with reasonable notice to existing subscribers.
8.2 Billing. Subscriptions are billed in advance via our payment processor (currently Stripe) on a recurring monthly basis. You authorize Lavender and our payment processor to charge your designated payment method for all recurring fees, applicable taxes, and any authorized plan additions.
8.3 Trials and Promotions. Trial periods, promotional rates, and introductory pricing, if offered, may have usage limits and time restrictions as described at the time of enrollment. Unless you cancel before the end of a trial period, your subscription may automatically convert to a paid plan at the then-current rate.
8.4 Grandfathered Pricing. Where Lavender has explicitly offered grandfathered pricing to early subscribers — meaning a commitment that your subscription rate will not increase as new features are added — that commitment applies to your specific subscription plan and remains in effect for as long as your subscription remains active and in good standing. Grandfathered pricing does not apply to plan upgrades, additional seats, or new products.
8.5 Refunds. Except as required by applicable law, all fees are non-refundable. We may offer discretionary credits or partial refunds on a case-by-case basis at our sole discretion, but are not obligated to do so. If you believe a charge was made in error, contact us at info@lavender-ts.com within 30 days of the charge.
8.6 Chargebacks. Initiating a chargeback or payment dispute without first contacting us in good faith to resolve the issue may result in immediate account suspension or termination. You remain responsible for any amounts owed regardless of a chargeback outcome.
8.7 Cancellation. You may cancel your subscription at any time in the Stripe billing portal, or by contacting us at info@lavender-ts.com. Cancellation takes effect at the end of the current billing period. Cancellation does not entitle you to a refund of any prepaid fees for the current billing period.
8.8 Editions Sold Under a Separate Agreement. Fees for Lavender Desk and Lavender Enterprise are established in the separate written agreement covering those editions and are not governed by this Section. Moving from a Service covered by this Agreement to such an edition is a new engagement, not a plan change, and any grandfathered pricing under Section 8.4 does not carry over to it.
9.1 Lavender's Intellectual Property. The Services, including all software, source code, object code, APIs, algorithms, pricing models, calibration methods, analytics engines, designs, interfaces, documentation, trademarks, and content, are the proprietary intellectual property of Lavender Trading Solutions LLC or its licensors. All rights not expressly granted to you under this Agreement are reserved by Lavender.
9.2 Limited License to You. Subject to your compliance with this Agreement and the terms of your subscription plan, Lavender grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the Services solely for your own personal or internal business purposes within your permitted subscription user count. This license does not include any right to resell, redistribute, sublicense, or make the Services available to third parties.
9.3 Restrictions. You acknowledge that the Services contain trade secrets and proprietary information belonging to Lavender. You agree not to attempt to discover, extract, replicate, or reverse engineer any proprietary algorithms, model parameters, calibration methods, pricing logic, or other trade secrets embedded in or derivable from the Services.
9.4 Feedback. If you provide feedback, suggestions, ideas, or recommendations regarding the Services, you grant Lavender a perpetual, irrevocable, worldwide, royalty-free, fully sublicensable license to use, reproduce, modify, and incorporate such feedback into the Services or any other product or service, without any obligation of compensation or attribution to you.
If you submit content, commands, queries, tickers, configuration settings, or other inputs through the Services, you represent that you have all necessary rights to submit such content and that it does not violate any applicable law or the rights of any third party. You understand that we may process your inputs to provide and improve the Services, subject to our Privacy Policy. We will not use your inputs or data to train competing models or share your individual usage data with third parties except as described in our Privacy Policy or as required by law.
The Services may integrate with or operate alongside third-party services including Discord, market data vendors, and cloud infrastructure providers. Lavender is not responsible for the availability, accuracy, reliability, data quality, pricing, or policy changes of any third-party service. Your use of third-party services, including any market data vendor whose API format is compatible with the Services, is governed solely by your agreements with those vendors. Lavender's vendor-compatible API endpoints do not create any relationship between Lavender and those vendors, and Lavender makes no representations regarding compatibility with future versions of any vendor's API.
We may suspend or terminate your access to the Services immediately and without prior notice if:
Upon termination, your license to use the Services immediately ceases. Sections 3, 4, 5, 9, 12, 13, 14, and 15 survive termination of this Agreement.
To the fullest extent permitted by applicable law, Lavender and its members, managers, officers, employees, contractors, agents, and licensors will not be liable for any:
To the fullest extent permitted by applicable law, Lavender's aggregate liability for all claims arising out of or related to the Services, regardless of the form of the action, will not exceed the total fees you paid to Lavender in the three (3) calendar months immediately preceding the event giving rise to the claim.
The limitations in this Section apply even if Lavender has been advised of the possibility of such damages and even if any limited remedy fails of its essential purpose. Some jurisdictions do not allow certain liability limitations, so some exclusions above may not apply to you.
You agree to defend, indemnify, and hold harmless Lavender Trading Solutions LLC and its members, managers, officers, employees, contractors, agents, successors, and assigns from and against any and all claims, demands, damages, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising out of or related to:
Governing Law. This Agreement is governed by and construed in accordance with the laws of the State of Wyoming, without regard to its conflict of law principles.
15.1 Informal Resolution. Before initiating any formal legal proceeding, you agree to contact Lavender at info@lavender-ts.com and attempt to resolve any dispute informally for a period of at least 30 days.
15.2 Dispute Resolution. Any dispute, claim, or controversy arising out of or relating to this Agreement or the Services that cannot be resolved informally shall be resolved by binding arbitration administered by a recognized arbitration provider under its then-current rules, on an individual basis. You waive any right to participate in a class action lawsuit or class-wide arbitration. Judgment on any arbitration award may be entered in any court of competent jurisdiction. Nothing in this Section prevents either party from seeking emergency injunctive or equitable relief in a court of competent jurisdiction where necessary to protect intellectual property rights or confidential information.
We may update this Agreement from time to time. When we do, we will update the "Last Updated" date at the top of this page. For material changes, we will make reasonable efforts to notify you by email or through the Services. Your continued use of the Services after any update constitutes your acceptance of the updated Agreement. If you do not agree to an update, you must stop using the Services and cancel your subscription.
Entire Agreement. This Agreement, together with the Privacy Policy and any plan-specific terms presented at checkout, constitutes the entire agreement between you and Lavender with respect to the Services and supersedes all prior agreements, representations, and understandings with respect to the Services. This Agreement does not supersede, amend, or limit any separate written agreement executed between you and Lavender covering another Lavender product, edition, or deployment; as to that product, edition, or deployment, the executed agreement is the entire agreement between the parties.
Severability. If any provision of this Agreement is found to be invalid, illegal, or unenforceable, that provision will be modified to the minimum extent necessary to make it enforceable, or severed if modification is not possible, and the remaining provisions will continue in full force and effect.
No Waiver. Lavender's failure to enforce any right or provision of this Agreement will not constitute a waiver of that right or provision.
Assignment. You may not assign or transfer this Agreement or any rights or obligations under it without Lavender's prior written consent. Lavender may assign this Agreement in connection with a merger, acquisition, corporate reorganization, or sale of all or substantially all of its assets.
Force Majeure. Lavender will not be liable for any delay or failure in performance resulting from causes beyond its reasonable control, including acts of God, natural disasters, pandemics, government actions, internet or infrastructure outages, or third-party service failures.
Headings. Section headings are for convenience only and have no legal or contractual effect.
No Third-Party Beneficiaries. This Agreement does not create any third-party beneficiary rights.
