Terms of Use

1. Agreement to these terms

These Terms of Use (“Terms”) are between you and Sightline Technologies Inc. (“we,” “us,” or “our”), providing Substrate, and govern the Substrate website and hosted products or services (collectively, the “Services”).

Using the Services means you agree to these Terms; otherwise, do not use them. Our Privacy Notice explains our personal-data practices and is incorporated only where law permits.

An order form, data processing addendum, statement of work, or other written agreement signed by us may contain additional or different terms. If there is a conflict, the signed agreement controls for its subject matter. Consumer use is not currently intended.

2. Eligibility and organizational authority

You must be at least 18 years of age and legally capable of entering a binding agreement to use the Services. If you use the Services for an organization, you represent that you are authorized to bind that organization, and “you” includes that organization.

You may not use the Services if doing so would violate applicable law, an obligation to another person, sanctions or export-control restrictions, or an instruction from your organization. We may request information reasonably needed to verify identity, authority, eligibility, or account use.

3. The Services

Substrate maintains qualified, source-aware memory about durable entities from agent sessions and supported connected sources.

Product descriptions, demonstrations, interface concepts, and API examples may be illustrative, not warranties, service levels, or future-feature commitments unless a signed agreement says otherwise. Synthetic demonstrations are not customer evidence.

4. Accounts, credentials, and access

If given an account, provide accurate information, protect credentials with reasonable safeguards, and promptly report suspected unauthorized access. Accounts are personal unless we approve otherwise; you are responsible for account activity to the extent law permits.

Access only the account, data, sources, entities, and features made available to you. Respect the access controls of every connected system.

5. Acceptable use

You must not, and must not help another person to:

• use the Services or outputs unlawfully, deceptively, discriminatorily, or to violate privacy, publicity, employment, intellectual-property, confidentiality, or other rights;
• submit or connect data you are not authorized to use for the agreed purpose;
• use Substrate for covert surveillance, stalking, harassment, manipulation, social scoring, sensitive-trait profiling, or to claim psychological certainty about a person;
• make a consequential decision about employment, housing, credit, insurance, education, healthcare, legal services, or access to an essential service solely on the basis of a Substrate output;
• treat inferred, uncertain, conflicted, or generated context as verified fact without appropriate review;
• attempt to bypass scope controls, access restrictions, rate limits, or security measures;
• probe, scan, test, or exploit a vulnerability except under our written authorization or an applicable published security-reporting policy;
• introduce malware, destructive code, unlawful content, or material that interferes with the Services or another user;
• reverse engineer, decompile, copy, scrape, or derive source code, models, non-public data structures, or underlying components except where a restriction is prohibited by law;
• use the Services to build a competing product from non-public functionality, documentation, or outputs, or to benchmark them for publication without written permission;
• misrepresent output provenance, remove notices, or imply that an output was reviewed or endorsed when it was not; or
• resell, sublicense, or provide access to the Services unless we agree in writing.

6. Customer, participant, and organizational data

“Customer Data” means data, content, instructions, source connections, and materials you or an organization provides, plus application records generated from them for your account. You retain your rights in Customer Data and grant us the limited right to host, copy, transmit, transform, derive, display, and otherwise process it to provide, secure, support, and administer the Services or as the applicable agreement states.

You represent and warrant that:

• you have all rights, permissions, notices, and lawful bases necessary to provide Customer Data and instruct us to process it;
• your instructions and intended use comply with applicable law, source-system terms, and your obligations to individuals and organizations; and
• you will not provide regulated, highly sensitive, or specially protected data unless we expressly approve it in a signed agreement with appropriate safeguards.

Source support varies. Connecting one transfers no ownership or additional rights; you remain responsible for configuration, authorization, accuracy, and continuing permission.

We will not populate one organization’s memory with another’s Customer Data. A signed agreement must expressly address rights to use customer data to improve generalized systems, models, quality methods, or evaluations; these Terms grant no unrestricted right to train on Customer Data.

7. Adaptive application outputs and human review

The Services may resolve entities, qualify context, distinguish facts from hypotheses or directions, retain provenance, surface conflicts, retrieve bounded context, and generate summaries, suggestions, or briefings. Probabilistic processes can produce incomplete, outdated, ambiguous, or incorrect results.

You must assess suitability, evidence, and uncertainty; correct errors where tools allow; and apply human judgment. Outputs are not professional advice or complete profiles and must not be presented as mind reading or psychological certainty.

You remain responsible for decisions, communications, and other uses of the Services or outputs.

8. Confidentiality

Each party may receive non-public information identified as or reasonably understood to be confidential, including product designs, security information, business plans, Customer Data, and non-public findings (“Confidential Information”). The recipient will use it only for the relationship, protect it reasonably, and disclose it only to personnel and advisers who need it and have appropriate obligations.

Confidential Information excludes information documented as lawfully known without restriction, independently developed without its use, rightfully received elsewhere, or public without breach. A legally compelled recipient may make the required disclosure after legally permitted notice and reasonable assistance at the discloser’s expense.

A signed nondisclosure or service agreement may replace or supplement this section, and controls for its subject matter where the two conflict.

9. Intellectual property

Substrate and its licensors own the Services, software, product design, documentation, site content, trademarks, underlying technology, improvements, and derivative works, excluding Customer Data and third-party materials. Subject to these Terms and signed agreements, you receive a limited, revocable, non-exclusive, non-transferable right to use the Services for the agreed purpose.

No rights are granted by implication. “Substrate” names and marks, and associated branding may not be used without prior written permission. You must preserve proprietary notices.

10. Feedback

You may provide feedback. Unless a signed agreement says otherwise, you grant us a perpetual, irrevocable, worldwide, royalty-free right to use and incorporate it without restriction or attribution, but not to identify you publicly or disclose your Confidential Information without permission.

Feedback is optional. Do not include third-party confidential information or grant rights you lack.

11. Third-party services and sources

The Services may use third-party infrastructure and authorized sources, including Microsoft Azure for app hosting and storage, OpenAI for fact extraction and Wiki pages with training disabled, Composio as one Gmail connection path and the Google Gmail API as the other, Clerk for authentication, Stripe for billing, Neon for the marketing-site database, Resend for email, and PostHog for configured analytics. Connected systems and other providers vary by account and configuration. Gmail use follows the Privacy Notice, including its Google Limited Use commitments.

Third-party services have their own terms and may change, suspend, or stop. We are not responsible for services beyond our control. You authorize necessary data exchange with connected services, subject to the applicable agreement and Privacy Notice.

12. Fees and taxes

Published self-serve plans are listed on the Pricing page. During the open beta there is no trial; fees are charged from the start of the subscription. Fees, including applicable taxes, are billed in advance through Stripe and are non-refundable except where the law requires otherwise. You owe applicable taxes except those on our net income.

13. Suspension, changes, and termination

We may limit or suspend access as reasonably necessary for security, law, material breach, harmful use, risk to people or the Services, provider outage, or service management. Where practicable, we will give notice and an opportunity to cure.

Either party may end participation under the applicable agreement. Without one, you may stop anytime and we may change or end service access on reasonable notice when practicable. Access then ends, while confidentiality, ownership, feedback, disclaimers, liability, dispute, general, and other provisions that by nature should survive do so.

Customer Data return, export, deletion, and retention follow the signed agreement and Privacy Notice. Do not use the Services as the sole repository for required records.

14. Disclaimers

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICES, SITE, FEATURES, CONTENT, AND OUTPUTS ARE PROVIDED “AS IS” AND “AS AVAILABLE.” SIGHTLINE DISCLAIMS ALL EXPRESS, IMPLIED, STATUTORY, AND OTHER WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, QUIET ENJOYMENT, AND ANY WARRANTY ARISING FROM COURSE OF DEALING OR USAGE OF TRADE.

We do not warrant uninterrupted, secure, error-free, complete, or universally compatible Services; accurate, current, or decision-suitable memory or outputs; corrected defects; or delivery of planned features, connectors, results, or dates. Some jurisdictions restrict disclaimers, so some may not apply to you.

15. Limitation of liability

To the maximum extent permitted by law, neither party is liable for indirect, incidental, special, consequential, exemplary or punitive damages, or lost profits, revenue, business, or lost or corrupted data, whether in contract, tort or otherwise, even if advised they were possible. Each party's total aggregate liability arising from the Service or these Terms will not exceed the greater of (a) fees you paid Sightline Technologies Inc. for the Service during the 12 months before the event giving rise to the claim or (b) US$100. Nothing here limits liability for gross negligence, willful misconduct, fraud, or liability that applicable law cannot limit.

This risk allocation is fundamental to the bargain and applies even if a limited remedy fails its essential purpose. Some jurisdictions restrict damage exclusions or limits, so parts may not apply. A signed agreement’s different allocation controls its subject matter.

16. Indemnity

You will defend, indemnify and hold harmless Sightline Technologies Inc. and its officers, directors, employees and agents against any third-party claim, demand, loss, liability, or expense, including reasonable attorneys' fees, arising from (a) content, signals, or data you submit or connect; (b) your use of the Service in violation of these Terms or law; or (c) your representation that you have the rights and authorizations to connect a source. We will promptly notify you, give you sole control of the defense and settlement—except that settlements imposing a non-monetary obligation on us require our prior written consent—and reasonably cooperate at your expense.

This section does not apply to the extent a claim arises from our own gross negligence, willful misconduct, or infringement of a third party’s intellectual property by the Services as we supplied them.

17. Governing law and dispute process

These Terms and related disputes are governed by the laws of the State of Delaware, United States, excluding its conflict-of-law rules and the United Nations Convention on Contracts for the International Sale of Goods.

The parties submit disputes to the state and federal courts located in New Castle County, Delaware, to whose exclusive jurisdiction and venue both parties consent. Either may seek equitable relief in any competent court to protect intellectual property or Confidential Information.

Before filing, each party will try in good faith to resolve the dispute by using Section 19 contacts and allowing 30 days to respond. These Terms require no arbitration and waive no jury-trial or class-proceeding right.

18. General terms

Changes. We may update these Terms prospectively by posting a revised version and effective date, with additional notice if required. Continued use constitutes acceptance only where law permits.

Assignment. You need our prior written consent to assign these Terms. We may assign them through merger, acquisition, reorganization, asset sale, or law, subject to law and signed agreements.

Notices. We may use the Services or relationship contact details. Send formal legal notices to Section 19’s contact.

Force majeure. To the extent law permits, neither party is liable for delay or failure beyond reasonable control, except payment obligations.

Relationship. The parties are independent contractors, not partners, franchisor and franchisee, joint venturers, fiduciaries, employer and employee, or principal and agent. No third party benefits unless a signed agreement says so.

Severability and waiver. An unenforceable provision will be minimally modified or severed; the rest continue. Waivers must be explicit and do not cover later breaches.

Entire agreement and interpretation. These Terms and applicable signed agreements are the entire agreement on their subject matter, replacing prior discussions. Headings are convenient; “including” means without limitation. Electronic communications and signatures may be used where lawful.
