Terms of Service

Last updated: March 31, 2026

Welcome to Sylly. These Terms of Service ("Terms") govern your access to and use of the Sylly website, applications, and services (collectively, the "Service") operated by Sylly ("Sylly," "we," "us," or "our"). By creating an account or using the Service, you agree to be bound by these Terms. If you do not agree, do not use the Service.

Please also review our Privacy Policy, which describes how we collect and use your personal information.

1. Eligibility

You must be at least 16 years of age to use the Service. If you are under the age of majority in your jurisdiction, you represent that your parent or legal guardian has reviewed and agreed to these Terms on your behalf. We do not knowingly collect personal information from children under 13 years of age. If we learn that we have collected information from a child under 13, we will promptly delete it. If you believe we have inadvertently collected such information, please contact us at support@sylly.ca.

2. Account Registration

To use the Service you must create an account and provide accurate, complete information including your name, email address, and username. You are responsible for maintaining the confidentiality of your password and for all activities that occur under your account. You agree to notify us immediately of any unauthorized use of your account.

You may not share your account credentials, transfer your account to another person, or create multiple accounts for the purpose of circumventing feature limits.

3. Description of the Service

Sylly is an AI-powered student operating system that helps post-secondary students organize, study, and succeed in their coursework. The Service includes features such as:

  • Class management, scheduling, and study planning
  • AI-powered study chat assistant
  • AI-generated study notes, flashcards, and practice tests
  • Lecture recording and transcription
  • Document upload and parsing
  • Friends, direct messages, and group chats
  • Grade tracking and evaluation management

4. Subscriptions and Payment

4.1 Free and Unlimited Plans

Sylly offers a free tier with limited usage and a paid "Unlimited" tier. The current pricing, features, and limits for each plan are displayed on our Pricing page. We reserve the right to change pricing and plan features at any time, with at least 30 days' notice to existing paid subscribers before any price increase takes effect.

4.2 Billing and Auto-Renewal

If you subscribe to the Unlimited plan, you will be billed on a recurring basis (monthly or annually, depending on the billing interval you select) at the rate displayed at the time of purchase. Your subscription will automatically renew at the end of each billing period unless you cancel before the renewal date. You authorize us to charge the payment method on file for each renewal period.

4.3 Cancellation

You may cancel your subscription at any time through the billing settings in your account or through the Stripe customer portal. Cancellation takes effect at the end of your current billing period — you will continue to have access to Unlimited features until then. We do not provide prorated refunds for partial billing periods.

4.4 Refunds

Payments are generally non-refundable. If you believe you have been charged in error, contact us at support@sylly.ca within 14 days of the charge and we will review your request.

4.5 Payment Processing

All payments are processed by Stripe, Inc. ("Stripe"). Your payment information (such as credit card numbers) is transmitted directly to Stripe and is never stored on our servers. Stripe's use of your information is governed by the Stripe Privacy Policy.

5. Acceptable Use

You agree not to use the Service to:

  • Violate any applicable law, regulation, or third-party rights
  • Submit content that is unlawful, defamatory, harassing, or obscene
  • Impersonate another person or misrepresent your affiliation
  • Submit academic work generated by the Service as your own in violation of your institution's academic integrity policies
  • Attempt to gain unauthorized access to any part of the Service, other users' accounts, or our systems
  • Reverse-engineer, decompile, or disassemble the Service
  • Use automated means (bots, scrapers) to access the Service without our written permission
  • Circumvent usage limits, rate limits, or security measures
  • Upload content that contains viruses, malware, or harmful code

We reserve the right to suspend or terminate your account if you violate these Terms, with or without notice.

6. AI-Generated Content

6.1 Nature of AI Output

The Service uses artificial intelligence (including Anthropic's Claude) to generate study notes, flashcards, practice tests, chat responses, and other educational content. AI-generated content is provided for educational and informational purposes only and may contain errors, inaccuracies, or omissions. You should always verify AI-generated content against your course materials and exercise your own judgment.

6.2 No Academic Guarantee

Sylly does not guarantee the accuracy, completeness, or suitability of any AI-generated content for any particular course, exam, or academic purpose. We are not responsible for any academic outcomes, grades, or consequences resulting from your use of AI-generated content.

6.3 Academic Integrity

It is your sole responsibility to understand and comply with your educational institution's academic integrity policies. Sylly is a study aid, not a substitute for your own work. Submitting AI-generated content as your own original work may constitute academic misconduct under your institution's policies. Sylly is not liable for any academic disciplinary actions resulting from misuse of the Service.

7. Lecture Recording

The Service includes a lecture recording feature. You are solely responsible for ensuring that you have the legal right and any required consent to record in your jurisdiction and under your institution's policies. Recording laws vary by jurisdiction:

  • Canada: Federal law (Criminal Code s. 184) allows one-party consent recording, meaning you may record a conversation you participate in. However, provincial privacy laws may impose additional requirements.
  • United States: Some states require all-party consent (e.g., California, Florida, Illinois). Check your state's laws before recording.

Many universities have their own recording policies that may be stricter than applicable law. You must check your institution's policy before recording any lecture. Sylly is not responsible for any legal or institutional consequences of unauthorized recording.

8. Your Content

8.1 Ownership

You retain ownership of all content you upload, create, or input into the Service ("Your Content"), including documents, recordings, notes, messages, and any other materials. Sylly does not claim ownership of Your Content.

8.2 License to Sylly

By using the Service, you grant Sylly a limited, non-exclusive, worldwide license to use, process, store, and transmit Your Content solely for the purpose of providing and improving the Service. This includes transmitting relevant portions of Your Content to third-party AI providers (as described in our Privacy Policy) to generate AI-powered features. This license terminates when you delete Your Content or your account.

8.3 Shared Content

The Service allows you to share certain content (notes, flashcards, practice tests) with other users. When you share content, the recipient receives a copy. You are responsible for ensuring you have the right to share any content you distribute through the Service.

9. AI-Generated Content Ownership

Content generated by AI features of the Service (notes, flashcards, practice tests, chat responses) is generated based on Your Content and your inputs. To the extent permitted by applicable law, you may use AI-generated content for your personal educational purposes. However, the copyright status of AI-generated content is evolving and may vary by jurisdiction. Sylly makes no representations regarding the copyrightability of AI-generated outputs.

10. Intellectual Property

The Service, including its design, code, features, logos, and branding, is owned by Sylly and protected by copyright, trademark, and other intellectual property laws. These Terms do not grant you any right to use Sylly's trademarks or branding. You may not copy, modify, distribute, or create derivative works of the Service.

11. Third-Party Services

The Service relies on third-party services to operate. These include, but are not limited to:

  • Anthropic (Claude API) — for AI-powered features
  • OpenAI (Whisper API) — for lecture transcription
  • Stripe — for payment processing
  • Supabase — for authentication, database, and file storage
  • Upstash — for rate limiting and usage tracking

Your use of the Service is also subject to the terms and policies of these third-party providers. Sylly is not responsible for the availability, security, or practices of third-party services.

12. Privacy

Our collection and use of personal information is governed by our Privacy Policy, which is incorporated into these Terms by reference.

13. Disclaimer of Warranties

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, AND NON-INFRINGEMENT.

14. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, SYLLY AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AND AGENTS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, USE, OR GOODWILL, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE SERVICE.

OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS RELATED TO THE SERVICE SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID TO SYLLY IN THE 12 MONTHS PRECEDING THE CLAIM, OR (B) ONE HUNDRED CANADIAN DOLLARS (CAD $100).

Some jurisdictions do not allow the exclusion or limitation of certain warranties or liability. In such jurisdictions, our liability shall be limited to the fullest extent permitted by law. Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, including liability for fraud.

15. Indemnification

You agree to indemnify, defend, and hold harmless Sylly and its officers, directors, employees, and agents from and against any claims, damages, losses, liabilities, and expenses (including reasonable legal fees) arising out of or related to: (a) your use of the Service; (b) your violation of these Terms; (c) your violation of any applicable law or third-party rights; or (d) Your Content.

16. Termination

You may delete your account at any time through the privacy settings in your account. Upon account deletion, we will delete your personal information and content in accordance with our Privacy Policy.

We may suspend or terminate your access to the Service at any time, with or without cause, and with or without notice. Upon termination, your right to use the Service ceases immediately. If your paid subscription is terminated by us without cause, we will provide a pro-rated refund of any prepaid fees.

17. Changes to These Terms

We may update these Terms from time to time. If we make material changes, we will notify you by email or by displaying a prominent notice within the Service at least 30 days before the changes take effect. Your continued use of the Service after the effective date constitutes acceptance of the revised Terms. If you do not agree to the updated Terms, you must stop using the Service and delete your account.

18. Governing Law and Dispute Resolution

These Terms are governed by and construed in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein, without regard to conflict of law principles.

Any dispute arising out of or in connection with these Terms or the Service shall first be attempted to be resolved through good-faith negotiation. If the dispute cannot be resolved within 30 days, it shall be submitted to the exclusive jurisdiction of the courts located in the Province of Ontario, Canada.

19. General Provisions

  • Entire Agreement: These Terms, together with the Privacy Policy, constitute the entire agreement between you and Sylly regarding the Service.
  • Severability: If any provision of these Terms is found to be unenforceable, the remaining provisions shall continue in full force and effect.
  • Waiver: Our failure to enforce any provision of these Terms shall not constitute a waiver of that provision.
  • Assignment: You may not assign or transfer these Terms without our prior written consent. Sylly may assign these Terms without restriction.
