Terms of Service
Effective June 22, 2026
Acknowledgment and assumption of risk
Skyline is an AI assistant for educators. Its scores, feedback, and originality signals are suggestions that can be inaccurate, incomplete, or unsuitable. By creating an account or using Skyline you acknowledge and accept that:
- A qualified human educator is the sole decision-maker. You will independently review AI output and are solely responsible for every grade, comment, and decision you issue.
- You will not rely on AI output as the only basis for any consequential decision about a student, and you will give students a way to question or correct results.
- You are authorized to upload the work and data you submit, and to do so consistent with FERPA, COPPA, and applicable state student-privacy law.
- You assume the risk of using an AI tool for grading and accept the disclaimers and the limitation of liability set out below.
1. Agreement and authority
These Terms govern access to Skyline, an AI-assisted grading service operated by Silvia Inc. ("Silvia," "we," "us"). By creating an account, accepting an order, or using Skyline, you agree to these Terms, our Privacy Policy, and our Safety and Responsible AI Policy.
If you use Skyline for a school, district, or other organization, you represent that you are authorized to use the service and provide the information submitted. You may bind the organization only if you have legal authority to do so. A signed order form, data protection agreement, or negotiated agreement controls over conflicting online terms.
2. Service and AI limitations
Skyline extracts student work, applies teacher-provided rubrics and answer keys, generates scoring suggestions and feedback, and supports teacher review, export, printing, and authorized gradebook posting.
AI output is probabilistic. It can misread handwriting, misunderstand context, apply a rubric incorrectly, omit evidence, or produce an unsuitable score or comment. Confidence scores are estimates, not guarantees.
Auto-post is disabled by default. A teacher who enables it instructs Skyline to approve grades above the chosen confidence threshold after product safety checks. The customer remains responsible for selecting the threshold, monitoring results, providing an appeal or correction path, and disabling auto-post if it is unsuitable. Teacher-specific calibration cannot by itself qualify work for auto-posting.
3. Appropriate educational use
- Use Skyline only for lawful, school-authorized educational purposes.
- Provide accurate rubrics, answer keys, grading scales, rosters, and instructions.
- Review uncertain, high-stakes, unusual, multilingual, inaccessible, or hard-to-read work with appropriate human judgment.
- Provide students a reasonable way to ask questions, correct errors, and seek review under school policy.
- Comply with applicable grading, records, accessibility, nondiscrimination, retention, and student-privacy obligations.
- Use professional judgment before acting on originality or academic-integrity indicators; they are advisory and are not proof of misconduct.
4. Accounts and security
Accounts are for authorized adults. You must protect credentials, use individual accounts, keep recovery information current, and promptly report suspected compromise. You are responsible for activity under your account until you notify us, except to the extent caused by Silvia's failure to use reasonable safeguards.
Do not expose private family links, exports, student work, or integration credentials to unauthorized people. A teacher who creates a link is responsible for choosing the correct recipient and using an approved communication channel.
5. Student data and legal authorization
The customer controls the educational purpose and must have a lawful basis to submit student records. Silvia processes those records to provide and secure the service, subject to the Privacy Policy and any applicable DPA.
A school's ability to authorize processing under FERPA, COPPA, or state student privacy law depends on the facts and governing agreement. Nothing in these Terms transfers duties that law places directly on Silvia. Customers should not upload student data until required institutional approval and contractual review are complete.
6. Prohibited conduct
You may not:
- Use Skyline for admissions, discipline, special-education eligibility, diagnosis, employment, credit, or another consequential decision without independent qualified human review and a lawful process.
- Use an AI score as the sole basis for punishment, accusation of cheating, denial of an opportunity, or another materially adverse action.
- Upload data you are not authorized to process or unnecessary highly sensitive information.
- Sell, advertise with, profile, or commercially exploit student data.
- Attempt to access another tenant, bypass authentication, probe production systems without written authorization, introduce malware, overload the service, or interfere with security controls.
- Reverse engineer the service except where law expressly permits, scrape it, resell access, or use outputs to build a competing grading model in violation of applicable rights.
- Upload unlawful, infringing, abusive, or dangerous content, or use the service to harass or discriminate.
- Misrepresent AI output as verified fact or conceal required human review.
7. Customer content and licenses
As between the parties, the customer, school, teacher, or student retains rights in content they lawfully own. You grant Silvia a limited, nonexclusive right to host, copy, transmit, transform, and process submitted content only as needed to provide, secure, support, and legally operate Skyline.
You represent that you have sufficient rights and authority for that processing. Silvia does not acquire ownership of student work. Product feedback that does not contain student personal information may be used to improve Skyline without a duty to compensate the submitter.
8. Silvia technology
Silvia and its licensors own Skyline, its software, design, documentation, models, workflows, and related intellectual property, excluding customer content. These Terms grant a limited, revocable, nontransferable right to use Skyline during the applicable subscription for authorized purposes.
9. Integrations and third-party services
Connected services are governed by their own terms and may change or become unavailable. You authorize Skyline to exchange the minimum data and perform the actions selected in the integration. You must verify roster mappings and grade destinations before posting. Silvia is not responsible for a third-party service outside our control, but remains responsible for its own selection and management of subprocessors as required by law and contract.
10. Fees, fulfillment, refunds, and renewals
Paid features, prices, usage limits, billing periods, renewal terms, and cancellation rights are shown at purchase or in an order form. Unless an order states otherwise, subscriptions renew for the selected period until canceled before renewal. Customers are responsible for applicable taxes other than taxes on Silvia's income.
Fulfillment. Skyline is a digital service delivered electronically. Access to the service, and to any paid features, is provisioned to your account immediately upon account creation or payment confirmation, and remains available for the purchased term. Nothing is physically shipped.
Cancellation and refunds. You may cancel a subscription at any time in your account settings or by emailing team.silviaai@gmail.com. Cancellation takes effect at the end of the current billing period, and you keep access until then. Fees already paid are nonrefundable, including for partial billing periods, except where a refund is required by applicable law, expressly stated at purchase, or granted at our discretion for duplicate charges or billing errors. To request a refund, contact team.silviaai@gmail.com with the account email and charge details; we respond within 10 business days.
We may change future pricing with advance notice. A price change does not alter a prepaid term unless the order permits it.
11. Privacy, confidentiality, and security
Our Privacy Policydescribes processing practices. Each party will use reasonable care to protect the other's confidential information and use it only for the relationship. Confidential information does not include information independently developed, rightfully received without restriction, or publicly available without breach.
We use safeguards appropriate to the service but cannot guarantee that every attack, outage, user error, or provider failure will be prevented. Security incidents are handled under applicable law, contract, and our incident-response process.
12. Changes, availability, and beta features
We may update Skyline to improve safety, performance, or functionality. We may modify or discontinue a feature, but will use reasonable efforts to avoid materially reducing paid core functionality during a prepaid term without notice or an appropriate remedy.
Preview, pilot, or beta features may be changed or withdrawn and should not be used for high-stakes workflows unless a written agreement says otherwise. Maintenance, internet failures, provider outages, emergencies, and events outside reasonable control may interrupt the service.
13. Suspension and termination
You may stop using Skyline or cancel as provided in the account or order. We may suspend access when reasonably necessary to prevent harm, investigate suspected abuse, address nonpayment, comply with law, or protect data. Where practicable, we will give notice and an opportunity to cure.
On termination, access ends. Data export and deletion follow the Privacy Policy, DPA, and applicable law. Sections that by their nature should survive, including ownership, payment obligations, disclaimers, limits, and dispute terms, remain effective.
14. Disclaimers
TO THE MAXIMUM EXTENT PERMITTED BY LAW, SKYLINE IS PROVIDED "AS IS" AND "AS AVAILABLE." SILVIA DISCLAIMS IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT AI OUTPUTS ARE ACCURATE, THAT THE SERVICE WILL BE UNINTERRUPTED, OR THAT EVERY SECURITY THREAT WILL BE PREVENTED.
These disclaimers do not limit an express written warranty or a right that cannot lawfully be waived.
15. Limitation of liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, NEITHER PARTY WILL BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE, OR CONSEQUENTIAL DAMAGES, OR LOST PROFITS, REVENUE, GOODWILL, OR DATA, ARISING FROM THESE TERMS, EVEN IF ADVISED OF THE POSSIBILITY.
EXCEPT FOR AMOUNTS THAT CANNOT LAWFULLY BE LIMITED, EACH PARTY'S TOTAL AGGREGATE LIABILITY ARISING FROM SKYLINE WILL NOT EXCEED THE GREATER OF (A) FEES PAID OR PAYABLE FOR SKYLINE DURING THE 12 MONTHS BEFORE THE EVENT OR (B) US $100. A SIGNED AGREEMENT MAY PROVIDE DIFFERENT LIMITS.
Nothing here excludes liability for fraud, willful misconduct, infringement, payment obligations, or other liability that applicable law does not permit the parties to exclude. Some jurisdictions do not allow certain limitations, so those limitations apply only to the extent lawful.
16. Indemnification
To the extent permitted by law, an organizational customer will defend and indemnify Silvia against third-party claims arising from content or data the customer lacked authority to provide, unlawful customer instructions, or material violation of these Terms. This obligation does not apply to the extent a claim results from Silvia's breach, negligence, or willful misconduct. Public schools are bound only to the extent their governing law permits.
17. Governing law and disputes
Unless a signed agreement or mandatory law says otherwise, California law governs these Terms without regard to conflict principles, and exclusive venue lies in the state or federal courts located in San Francisco County, California. Before filing a claim, the parties will attempt in good faith for 30 days to resolve it through written notice, unless urgent injunctive relief is reasonably necessary.
Any claim or dispute arising out of or relating to Skyline must be filed within one (1) year after the claim first accrued; otherwise it is permanently barred, except where a longer period is required by law that cannot be waived. To the extent permitted by applicable law, each party will bring claims only in an individual capacity and not as a plaintiff or class member in any purported class or representative proceeding.
18. General terms
These Terms and incorporated documents are the entire agreement for the online service unless a signed agreement applies. If a provision is unenforceable, it will be limited to the minimum extent necessary and the rest remains effective. Failure to enforce a provision is not a waiver. You may not assign these Terms without consent, except in an authorized organizational restructuring. Silvia may assign them in connection with a merger, acquisition, or sale, subject to applicable student-data restrictions.
We may update these Terms with notice appropriate to the change. Material changes will apply prospectively. Continued use after the effective date constitutes acceptance where permitted by law.
