Terms of Service & End User License Agreement

This agreement is between you and Ethoseen LLC, an Oregon limited liability company (“Ethoseen,” “we,” “us”).

It governs your use of Sightline: the desktop application, the iOS and watchOS companion apps when paired with it, the machine-learning models and adapters it downloads, and the sightlinebehavior.com website and services (the applications, Models, and Adapters are the “Software”; the website and related licensing, billing, and support services are the “Services”).

By affirmatively accepting these terms in the app or at checkout, you accept this agreement and represent that you are at least 18 years old and able to form a binding contract. If you do not agree, do not use the Software or Services.

Plain-language summary (not a substitute for the terms): You’re buying a license for one person on one desktop computer. We claim no ownership of your records or work product. Observation storage and AI processing take place on your devices. Review AI drafts before relying on them, and record lawfully. Do not extract or redistribute our proprietary software or adapters. If your paid plan ends, saved observations remain exportable as CSV; paid analysis and drafting features require an active plan. Annual plans have a 30-day refund policy.

1. Definitions

“Desktop App”: the Sightline application for macOS and Windows.
“Companion App”: the Sightline companion for iPhone and Apple Watch.
“Models”: third-party machine-learning model files the Software downloads (base language models, speech-recognition and diarization models).
“Adapters”: Ethoseen’s proprietary fine-tuned model weights and adapter files, delivered only to licensed installations.
“AI Outputs”: draft text or analyses generated by the Software’s machine-learning features, including summaries and draft write-up sections. This term does not include ordinary exports or deterministically computed measures, tables, and figures.
“Your Content”: data you enter, import, create, or record with the Software: students, sessions, observations, notes, audio, exports, authored drafts, and AI Outputs.
“Subscription”: a paid Starter or Pro plan.

2. Your license

Subject to these terms, we grant you a personal, non-exclusive, non-transferable, non-sublicensable license to install and use the Software for your own professional or personal use.

One person, one desktop. A license (including the free tier and trial) is personal to you as an individual and may be activated on one desktop device at a time. You may deactivate a device to move your license to another. The Companion App pairs with your licensed desktop and does not consume an activation.
Employer reimbursement doesn’t transfer the license. If your school, district, or employer reimburses or pays for your Subscription, the license remains assigned to you individually; payment does not grant additional software seats or access. This does not determine ownership of, or access rights to, records or work product under your employment arrangements or applicable law. Institutions interested in site licensing: contact us.
Licensed, not sold. The Software, including the Adapters and Ethoseen’s prompts and protocols, is licensed to you, not sold. We and our licensors retain all rights not expressly granted.

3. Restrictions

You may not, and may not permit or help anyone else to:

Reverse-engineer: decompile, disassemble, or otherwise attempt to derive the source code, prompts, protocols, or internal logic of the proprietary Software, or extract proprietary Adapter weights from it, except to the extent permitted by applicable law or the third-party licenses described in Section 11.
Circumvent protections: bypass, disable, or interfere with license validation, activation limits, trial enforcement, entitlement checks, model delivery authentication, or encryption.
Systematically extract proprietary functionality: use automated or systematic querying to extract or replicate our proprietary prompts, protocols, or Adapter behavior for a competing product or model, including assembling AI Outputs from that activity into model-training datasets. This does not restrict your use of your own source records, ordinary professional use of AI Outputs and exports, comparison of tools for your practice, or moving your data to another product.
Operate it as your own service: provide the Software’s functionality to others as or within your own product or service, including white-labeling it, reselling access to it, or generating reports or write-ups as a hosted, automated, or pass-through offering in which your customer supplies the observation data and receives the deliverable without substantive professional review; or present the Software’s technology as your own. This does not restrict professional observations, evaluations, consultation, or reviewed work product for students and clients, including work using records supplied by authorized colleagues or informants. You may truthfully identify Sightline as a tool you use, without implying our endorsement of your services.
Extract or redistribute the Adapters: copy an Adapter out of the Software, run it outside the Software, fine-tune on top of it, or make it available to anyone else. Adapters are licensed for use inside the Software only.
Share, resell, or transfer your license, license key, or trial credential, or use another person’s.
Misrepresent AI Outputs: present an AI Output as the work of a qualified professional without the review Section 7 requires.

A breach involving our proprietary software or Adapters may cause harm that money damages cannot adequately remedy. We may seek injunctive or other equitable relief, subject to applicable law and the court’s requirements.

4. Recording and authority to use records

The Software can record audio and can capture observation data about people who are not parties to this agreement.

Lawful recording. Before recording audio, obtain the consents, notices, authorizations, and approvals required by applicable law and the policies of your school, district, agency, or employer. The Software does not obtain these permissions for you.
Authority to use records. You must have authority to create, import, hold, and process records about the students, clients, or other people you document, and to make any resulting disclosures. You and, where applicable, your institution are responsible for record access, retention, and handling in accordance with applicable law and policy.

5. Tiers, trial, and free tier

Free tier. Requires no payment or account. Its feature set is described on the website and may change.
Paid tiers. Starter and Pro. Their feature sets are described on the website and may change.
Trial. New users receive one trial of the Pro tier lasting 21 calendar days from first activation: one trial per person, enforced as one trial per desktop device. To enforce this, the Software derives a hashed device identifier from your hardware and records it with our trial service; the identifier is not derived from and does not contain Your Content. See the Privacy Policy. Obtaining additional trials by resetting, spoofing, or rotating device identifiers violates Section 3. When a trial ends, the Software reverts to the free tier.
Access after a trial or paid plan ends. Expiration, cancellation, non-payment, or a failed license validation does not delete Your Content. Saved observations remain exportable as CSV. Viewing computed results, formatted PDF export, and access to FBA drafts, including prose you typed yourself, require the applicable paid tier. Files you already exported remain available independently of the Software. Termination for material breach is addressed separately in Section 14.

6. Subscriptions, billing, and refunds

Billing. Subscriptions are billed monthly or annually through our payment processor. Prices are posted on the website. Taxes may apply. Subscriptions renew automatically until cancelled; cancellation takes effect at the end of the paid period, except for early termination under Section 19. You do not need to accept unchanged terms again at each renewal. A renewal charge is not acceptance of updated terms.
How to cancel. Open Settings → Plan → Manage subscription in the app, or use the billing portal on the website. The website route may require an emailed sign-in link. You can complete cancellation without contacting support; contact us if you cannot access your license or billing email. Cancellation stops the next renewal charge; you keep paid features through the end of the period you paid for. The renewal terms (amount, frequency, and how to cancel) are disclosed at checkout, immediately above the control you use to confirm the purchase, and completing checkout is your affirmative consent to those terms and the recurring charge.
Launch pricing. Promotional “launch” rates, where offered, remain in effect for as long as the Subscription remains active and continuously paid; a lapsed Subscription re-subscribes at then-current pricing.
30-day refund policy (annual plans). If you ask within 30 days after any annual Subscription charge, we will refund that charge in full, for any reason. This includes renewals. The 30-day deadline applies to your request, not to when we process it. If you have already received a refund under this policy, we may decline another. A refund under this policy ends the Subscription and its paid features when we issue it. Monthly plans may be cancelled anytime; ordinary monthly refunds are at our discretion. The separate refunds for rejecting updated terms in Section 19 apply to monthly and annual plans, including renewals, and follow their own rules. These are refund policies, not warranties of the Software’s performance.
Price changes. We may change prices with at least 30 days’ notice; changes apply at your next renewal. Launch-price locks survive price changes per above.
Statutory cancellation rights. If you buy as a consumer in the European Union or the United Kingdom, you may have a statutory 14-day right to withdraw. We do not treat accepting these terms, starting a trial, or using the Software as a waiver of that right. To exercise a right to withdraw, send an unequivocal statement identifying your purchase to [email protected] or our postal address in Section 20. You may use the model withdrawal form in our Refund Policy. Any statutory refund is handled under applicable law, independently of our voluntary refund policy above.

7. AI features and professional responsibility

AI Outputs are drafts. The Software generates them on your device. They may contain errors, omissions, or mischaracterizations, even when source records are accurate.
Review before use. Review AI Outputs against your source records and apply independent professional judgment before relying on them in an evaluation, report, or decision affecting a person. Do not use an AI Output as the sole basis for an assessment conclusion or recommendation.
Intended use. The Software supports observation documentation and drafting. It is not intended to diagnose or treat a condition, or to make eligibility, placement, disciplinary, clinical, or educational decisions. Use it within the qualifications and authority required for your role.
Your Content. As between you and Ethoseen, you retain your rights in Your Content, including AI Outputs. We claim no ownership of it. These terms do not determine rights belonging to your institution, clients, or other people under applicable law or your agreements with them.

8. Your data and privacy

Local storage and processing. Observation records and drafts are stored on your devices and processed there, including by AI features. Companion transfers take place between your paired devices. We do not operate cloud storage or remote AI processing for those records and cannot access them through the observation workflow. Backups are your responsibility, and so is removal. Securely delete Your Content before selling, transferring, or disposing of a device, since we cannot do it for you.
What does leave your machine (license validation, opt-in analytics, opt-in crash reports, update checks, model downloads, trial enforcement, and feedback you choose to send) is described in the Privacy Policy, which is part of this agreement. Analytics and crash reporting are disabled unless you enable them.
Support and feedback. We receive information you choose to send us. Do not include identifiable student or client records in support or feedback submissions. The Privacy Policy explains how submissions and optional diagnostics are handled.
Student records. Your institution’s approval, privacy, device-security, access, retention, and disclosure policies still apply to your use of the Software, as do applicable laws, including FERPA, IDEA, and state law. Local storage does not replace those requirements. We do not use student information for advertising, profiling, sale, or model training.

9. License validation and offline use

The Software validates paid licenses periodically against our licensing service and continues working offline between validations, with a grace window after a failed validation. If validation cannot succeed for an extended period, the Software reverts to the free tier until validation succeeds, non-destructively, per Section 5. Tampering with the system clock or validation mechanism is a violation of Section 3.

If we ever permanently discontinue the licensing service, we will release an update that keeps paid features working without validation for the remainder of any paid Subscription term, or refund the unused portion of what you prepaid. Saved observation data remains exportable as described in Section 5.

10. Support

We provide support at our discretion through the channels listed on the website. We do not commit to any response time, availability window, or service level, and support is not a condition of your license. This does not limit our cancellation, refund, or other express obligations in these terms.

11. Third-party models and components

Models are third-party. The Models are developed by third parties, downloaded separately at your direction from third-party or Ethoseen-operated servers, and governed by their own licenses, identified in the third-party notices. Those licenses govern your use of the Models.
Third-party rights are preserved. Restrictions in this agreement do not limit rights granted by the applicable licenses for third-party Models or components. Our proprietary Adapters remain subject to Section 3, together with any applicable base-model license conditions identified in the notices.
Open-source components. The Software includes open-source software listed with its licenses in the notices linked above. Those licenses govern those components.
Proprietary fonts and other proprietary licensed assets included in the Software may not be extracted or reused outside it unless their applicable license permits that use. Open-source fonts remain governed by their own licenses, as identified in the notices. These restrictions do not prevent ordinary use and sharing of documents exported by the Software.

12. Updates

The Desktop App checks for updates and downloads cryptographically signed updates from our update service. Update checks transmit no student data. We may require a current version for continued license validation or support. Features may change between versions. The saved-observation export access described in Section 5 remains available, subject to termination under Section 14.

13. Companion App

The Companion App’s App Store license is governed by Apple’s standard Licensed Application End User License Agreement. This agreement governs your use of the Companion App with Sightline and our Services. It supplements, and does not replace, Apple’s standard agreement; that agreement controls the App Store license if the two conflict.

The Companion App stores observation data locally and transfers it to your paired desktop over Bluetooth. Its storage, transfer, and deletion behavior is described in the Companion Privacy Policy.

14. Term and termination

These terms apply for as long as you use the Software or Services.
You can stop at any time: cancel any Subscription and delete the Software. Your Content remains yours; export it before deleting.
We may suspend or terminate your license, including the free-tier license, if you materially breach these terms (in particular Sections 3 and 4) and, where the breach is curable, you fail to cure it within 14 days of notice. Non-payment ends paid access under Section 5. Upon termination for breach, your right to use the Software ends, paid features cease at the next license validation, and you must, on our request, delete the Software and all Adapters and confirm you have done so. Before deletion, you may use the Software solely to export saved observations as CSV or make a local backup of your database. This limited permission does not restore paid features or permit continued observation or drafting. Sections 1, 3, 7, 8, 11, 13, and 15–20 survive termination.
Termination gives us no right to delete Your Content. Files you already exported remain available independently of the Software. A database backup is not a substitute for an exported document and may require compatible software and the applicable license to open.

15. Warranty disclaimer

To the extent permitted by applicable law, the Software and Services are provided “as is” and “as available,” with all faults, and without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, non-infringement, or that the Software or AI Outputs will be accurate, error-free, or uninterrupted. This disclaimer does not limit our express commitments in this agreement, the refund policy in Section 6, or warranties and remedies that applicable law does not allow us to exclude.

16. Limitation of liability

To the fullest extent permitted by law: (a) neither party is liable for indirect, incidental, special, consequential, or punitive damages, or lost profits or data; and (b) our total liability under these terms is capped at the amounts you paid us in the 12 months before the event giving rise to the claim (or $50 if you have paid nothing). The exclusion in (a) does not exclude amounts payable to a third party under Section 17. Neither (a) nor (b) limits liability for fraud, willful misconduct, or liability that applicable law does not allow to be excluded or limited.

17. Indemnity

You will defend and indemnify us against third-party claims to the extent caused by your unlawful recording or disclosure of records, intentional infringement or misappropriation of intellectual property through use of the Software, or knowing use of AI Outputs in violation of Section 7. This does not cover claims to the extent caused by our breach of this agreement, negligence, or willful misconduct.

We must promptly notify you of a claim, allow you to control its defense with qualified counsel, and provide reasonable cooperation at your expense. A delay in notice reduces your obligations to the extent it materially prejudices the defense. You may not settle a claim in a way that admits fault by us or imposes an obligation on us without our written consent, which we will not unreasonably withhold.

18. Governing law and disputes

These terms are governed by the laws of the State of Oregon, without regard to conflict-of-laws rules. The state courts located in Lane County, Oregon and the United States District Court for the District of Oregon have exclusive jurisdiction and venue, and both parties consent to personal jurisdiction there. No mandatory arbitration. No jury-trial waiver is included. Before filing any claim, the parties will first try to resolve the dispute informally: send a written description of the dispute to the other party’s notice address (Section 20) and allow 30 days for resolution. Either party may bring a qualifying claim in small-claims court instead of the courts above.

19. Changes to these terms

Notice and acceptance. We may update these terms. For material changes, we will give at least 30 days’ advance notice before the stated effective date, by email to paid subscribers and by a notice made available in the app. The notice will summarize the changes, link to the full updated terms, state the effective date, and explain how to cancel or reject the update.

The full updated terms are presented in the app for your acceptance before you continue using it. Updated terms apply to your use from acceptance, no earlier than their stated effective date, and do not apply retroactively. The app records the document versions and acceptance date. Neither silence nor an automatic renewal charge is acceptance of updated terms. Changes to the Privacy Policy that materially affect data handling follow the same notice and acceptance process. Price changes remain subject to Section 6. Any additional notice or consent required by applicable law will be provided.

For this section, the acceptance presentation date is the date when the full updated terms are first shown to you in the app for your acceptance. This is separate from any advance notice. Receiving or opening an advance notice, or following its link to read the proposed terms, does not start the rejection window.

If you reject an update. Before accepting it, email [email protected] within 30 days after the acceptance presentation date. Identify your Subscription and say that you reject the update. This is also a request to stop renewal; we will stop renewal and confirm the outcome by email. You may turn off renewal yourself at any time through the billing portal, but portal cancellation alone does not request a refund under this section.

Finishing your paid term. If we can continue providing your paid access under the terms you already accepted, we may offer that option through the end of your current paid period, without renewal. We do not promise to maintain or support a separate older version of the Software. You may instead choose early termination with the unused-term refund below.
Unused-term refund. If you end your Subscription because you reject the update, we will refund the prepaid fees attributable to the unused portion of your current paid period. The refund period starts on the date you stop ordinary use because of the update, no earlier than the acceptance presentation date, and ends at your existing paid-through date. We calculate the refund by calendar days, counting the starting day in your favor, and will not reduce it because processing your request takes time. Paid access ends when we process the termination.

The unused-term refund applies to initial and renewed paid periods alike; rejection does not itself entitle you to a refund for time already used. We may offer an additional goodwill refund at our discretion. This does not limit your separate 30-day annual refund under Section 6 or any refund required by applicable law.

After choosing termination, stop ordinary use of the Software. You may still use the offered export or backup path to retain your saved observation data; using that path is not acceptance of the update and does not disqualify your refund. Termination does not delete Your Content. This limited permission does not restore paid analysis, formatted PDF export, or drafting features.

We will issue a refund due under this section within 14 days after receiving your request, using the original payment method unless you agree otherwise, without a refund fee. Payment-provider posting times may vary. The Refund Policy explains what to include in your request. Nothing in this section limits rights or remedies that applicable law does not allow you to waive.

20. General

Entire agreement. These terms, the Privacy Policy, and, for the Companion App, the Companion Privacy Policy form the agreement between you and us and supersede prior discussions. The third-party licenses identified in Sections 11 and 13 remain applicable.
No third-party beneficiaries. This agreement is for the benefit of you and Ethoseen only and creates no contractual rights in any student, parent, client, employer, institution, or other person. It does not limit rights those people have independently under applicable law or Apple’s standard agreement.
Notices. We give you notice in the app (deemed given when the app next presents it) and, for paid subscribers, by email to the billing address on file. You give us notice at [email protected] or by mail to Ethoseen LLC, 1538 E 25th Avenue, Eugene, OR 97403, United States. Free-tier notice is in-app only, since we hold no contact information for you.
Feedback. If you send suggestions or ideas for improving the Software, you grant us a perpetual, irrevocable, royalty-free license to use them for that purpose without compensation. This license does not include student or client records, personal information, or other Your Content included in a submission. Handling of submissions remains subject to the Privacy Policy.
Force majeure. Neither party is liable for delay or failure caused by events beyond its reasonable control (including outages of third-party licensing, hosting, or model-distribution services), except for your payment obligations.
Assignment. You may not assign this agreement. We may assign it in connection with a merger, acquisition, or sale of assets.
Severability; waiver. If a provision is unenforceable, the rest stands. Failure to enforce is not waiver.
Mandatory consumer rights. Nothing in these terms excludes or limits any right or remedy you have under the consumer-protection law of your country of residence that cannot be excluded or limited by agreement. Where such a law conflicts with these terms, that law governs to the extent of the conflict.
Export. You may not use the Software in violation of applicable export and sanctions laws, and you represent that you are not located in an embargoed country and are not on any restricted-party list.
California users. Under Cal. Civ. Code § 1789.3, California residents may reach the Complaint Assistance Unit of the Division of Consumer Services of the California Department of Consumer Affairs in writing at 1625 North Market Blvd., Suite N 112, Sacramento, CA 95834, or by telephone at (800) 952-5210.
