Terms of Service

1. The agreement

These Terms of Service (the “Terms”) are a legal agreement between you and Jacob Knox, an individual residing in Illinois, doing business as “Arcavelo” (“Arcavelo,” “we,” “us,” or “our”). They govern your use of the Arcavelo website at arcavelo.app, the Arcavelo web app, any Arcavelo mobile app, and every feature and service we offer through them (together, the “Service”).

By signing in to or otherwise using the Service, you agree to these Terms. If you do not agree, do not use the Service.

These documents are part of these Terms and apply to you as well:

• the Privacy Policy, which explains how we handle your information;
• the Acceptable Use Policy;
• the AI Supplementary Terms, if you use syllabus import or Arc;
• the Subscription and Refund Policy, if you buy a paid plan;
• the Cookie Notice and the Copyright and DMCA Policy.

If one of those documents conflicts with these Terms on a point it specifically covers, that document controls on that point.

2. Who may use Arcavelo

To use the Service you must:

• be at least 18 years old;
• be able to form a binding contract under the law that applies to you;
• not be barred from using the Service under the laws of the United States or any other applicable country; and
• not have had an Arcavelo account previously terminated by us for breaking these Terms.

The Service is designed for college and university students and is not directed at anyone under 18. If we learn that an account belongs to someone under 18, we will close it and delete its data as described in the Privacy Policy.

The Service is operated from the United States. If you use it from somewhere else, you do so on your own initiative and are responsible for following your local laws.

3. Your account

You sign in to Arcavelo with a Google account. There is no separate Arcavelo password. You are responsible for keeping that Google account secure, and for everything that happens in Arcavelo while you are signed in. Tell us promptly at support@arcavelo.app if you believe someone else has accessed your Arcavelo account.

Each account is for one person. Do not share your account, sign in as someone else, or create accounts in bulk or by automated means.

If you sign in with a Google account issued by your school or employer, that organization may control the account, including whether it can reach Arcavelo and whether it can see or remove data connected to it. Your agreement with that organization is between you and it. For a personal planner, a personal Google account is usually the better choice.

4. What the Service is

Arcavelo is a personal academic planner. It helps you keep track of classes, assignments, grades, schedules, degree progress, goals, clubs, habits, and related information. It can sync with your own Google Calendar and Google Tasks, and it offers optional AI features described in the AI Supplementary Terms.

Arcavelo is an independent product. It is not affiliated with, endorsed by, or connected to any school, college, or university, and nothing in the Service is an official record. Grades, GPA figures, degree progress, and deadlines shown in Arcavelo are calculated from what you enter. Your school’s own records and your instructors are always the authority. Arcavelo does not give academic, legal, financial, medical, or mental-health advice.

Some features may be labelled beta, preview, or early access. Those features are still being tested, may change or be removed without notice, and may not work as well as the rest of the Service.

5. Your content

“Your Content” means everything you enter, upload, sync, or create in the Service, including classes, assignments, grades, notes, uploaded files and images, messages you send to Arc, and the content Arc and syllabus import produce for you.

You own Your Content. We do not claim any ownership of it. You give us a worldwide, non-exclusive, royalty-free license to host, store, copy, process, transmit, and display Your Content only as needed to run the Service for you, to keep it secure, and to comply with the law. That includes sending it to the service providers listed on our Subprocessors page when a feature you use needs them. This license ends when Your Content is deleted from the Service, except for copies that remain for a short time in backups as described in the Privacy Policy.

We do not sell Your Content, use it for advertising, or use it to train AI models, and we do not allow our AI provider to use it for training.

You are responsible for Your Content. You promise that you have the right to upload it (for example, the right to use a syllabus you import for your own studies) and that it does not break the law or the Acceptable Use Policy. We do not review Your Content as a matter of course, but we may look at, disable, or remove content if we reasonably believe that is needed to investigate a report, to enforce these Terms, to fix a problem you have asked us to fix, or to comply with the law.

We work to keep Your Content safe, but no service can promise it will never lose data. Keep your own copy of anything you cannot afford to lose. You can ask us for a copy of your data at any time, as described in the Privacy Policy.

6. Google Calendar and Google Tasks

If you connect Google Calendar and Google Tasks, you authorize Arcavelo to read and write your calendars and task lists on your behalf, in the ways described in the Privacy Policy. Arcavelo creates its own “School” calendar and “Arcavelo” task list, and it reads events from your other calendars to show your schedule and, if you use Arc, to answer questions about your schedule.

Your use of Google’s services is governed by Google’s own terms. We do not control Google, and syncing depends on Google’s systems being available and on Google continuing to allow it. You can revoke Arcavelo’s access at any time from your Google Account permissions page.

7. AI features

Syllabus import and Arc, the AI advisor, are governed by the AI Supplementary Terms in addition to these Terms. In short: AI output can be wrong; you must check it before relying on it; nothing is added to your planner or your Google Calendar until you confirm it; and you are responsible for what you choose to confirm and how you use what the AI produces, including following your school’s academic integrity rules.

As described in the Privacy Policy, Arc may read your Google Calendar events to answer schedule questions and may search the public web for relevant current information. An existing calendar event is moved only after you review and confirm the proposed change.

8. Acceptable use

You agree to follow the Acceptable Use Policy. Among other things, you may not use the Service to break the law, to harm or harass anyone, to get into another person’s account or data, to disrupt or overload the Service, to get around usage limits or payment, or to copy, scrape, or reverse-engineer the Service.

9. Free and paid plans

Everything needed to plan a semester by hand is free. Syllabus import and Arc cost money to run each time they are used, so they come with usage allowances, and larger allowances are sold as paid plans. Current plans, prices, and allowances are shown on the plans page.

Each paid plan has two kinds of AI limit: an allowance of Arc messages and syllabus imports, and a monthly AI usage limit. The AI features stop at whichever you reach first, so heavy use can reach the usage limit before the allowance is used up. The AI Terms explain both.

If you buy a paid plan, the Subscription and Refund Policy applies. It explains that paid plans renew automatically until you cancel, how to cancel from Settings, how price changes are announced, and when refunds are given. Payments are processed by Stripe; we never see or store your full card number.

We may change what the free plan includes and what each paid plan includes. A change will not reduce what you have already paid for during your current billing period.

10. Our intellectual property

The Service, including its software, design, text, graphics, logos, and the name “Arcavelo,” belongs to us or our licensors and is protected by copyright, trademark, and other laws. Your Content is not part of this; it stays yours.

Subject to these Terms, we give you a personal, limited, non-exclusive, non-transferable, revocable license to use the Service for your own personal, non-commercial academic planning. You may not copy, modify, distribute, sell, or lease any part of the Service, or use the Arcavelo name or logo in a way that suggests we endorse you, without our written permission. Any rights not expressly granted in these Terms are reserved.

11. Feedback

If you send us ideas, suggestions, bug reports, or other feedback, including through the in-app feedback form, you give us permission to use it to improve the Service without owing you anything. We are not required to use any feedback, and we will not publish your name alongside it without your permission.

12. Third-party services and links

The Service relies on third-party services, including Google, Stripe, and Anthropic, and may link to websites we do not control. We are not responsible for third-party services or websites, and your use of them may be governed by their own terms and privacy policies.

13. Privacy

The Privacy Policy explains what information we collect, how we use it, who we share it with, how long we keep it, and how you can access or delete it. By using the Service you acknowledge that we will handle your information as it describes.

14. Copyright complaints

We respect copyright. If you believe something in the Service infringes your copyright, follow the process in the Copyright and DMCA Policy. We close the accounts of repeat infringers in appropriate circumstances.

15. Suspension and termination

By you. You may stop using the Service at any time. You can delete your account and its data from Settings, which ends these Terms between us. If you have a paid plan, cancel it first; deleting your account also cancels it, but does not by itself entitle you to a refund except as the Subscription and Refund Policy says.

By us. We may suspend or close your account, or limit your access to some features, if you break these Terms or any policy that is part of them, if your use creates a risk of harm or legal liability for us or others, if we are required to by law, or if your account has been inactive for more than 24 months. Where it is reasonable to do so, we will tell you why and give you a chance to fix the problem first. If we close a paid account for a reason other than your breach, we will refund the unused part of your current billing period.

Getting your data out. Unless we close your account because of a serious breach or a legal requirement, we will give you at least 30 days to request a copy of your data before we delete it.

Sections of these Terms that by their nature should survive termination will survive, including those on Your Content licenses already exercised, feedback, our intellectual property, disclaimers, limitation of liability, indemnification, disputes, and the general terms.

16. Changes to the Service

Arcavelo is run by one person and is still growing. We may add, change, or remove features at any time, and we may suspend or discontinue the Service entirely. If we decide to shut the Service down, we will give you at least 30 days’ notice when we reasonably can, time to download your data, and a refund for any unused part of a paid plan.

17. Changes to these Terms

We may update these Terms from time to time. We will change the “Last updated” date at the top of this page each time. If a change materially reduces your rights or increases your obligations, we will tell you at least 14 days before it takes effect, by a notice in the app or by email. Changes needed to meet a legal requirement, or that only concern new features, can take effect immediately.

If you do not agree to a change, stop using the Service and delete your account before the change takes effect. If you keep using the Service after it takes effect, you accept the updated Terms. A change will never apply to a dispute that arose before the change was posted.

18. Disclaimers

The Service is provided “as is” and “as available.” To the fullest extent permitted by law, we disclaim all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, title, and non-infringement, and any warranties arising from course of dealing or usage of trade.

Without limiting the paragraph above, we do not promise that the Service will be uninterrupted, secure, or error-free; that data will never be lost; that syncing with Google will always work; or that grades, GPA figures, degree progress, deadlines, AI output, or any other information in the Service will be accurate, complete, or current. You are responsible for checking important information against your official school records before relying on it.

Some jurisdictions do not allow certain warranties to be disclaimed, so some of this section may not apply to you.

19. Limitation of liability

To the fullest extent permitted by law, Arcavelo and its operator will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, goodwill, or academic standing (including a missed deadline or a lower grade), arising out of or relating to these Terms or the Service, whether based on contract, tort (including negligence), statute, or any other legal theory, even if we were told such damages were possible.

To the fullest extent permitted by law, our total liability for all claims arising out of or relating to these Terms or the Service is limited to the greater of (a) the amount you paid us for the Service in the 12 months before the event giving rise to the claim, or (b) one hundred U.S. dollars (US$100).

These limits apply even if a remedy fails of its essential purpose. They do not limit liability that cannot be limited under applicable law, such as liability for fraud, gross negligence, or willful misconduct in some jurisdictions. Some jurisdictions do not allow these kinds of limits, so some of this section may not apply to you.

20. Indemnification

If a third party brings a claim against us because of Your Content, your breach of these Terms, or your violation of the law or of someone else’s rights, you agree to cover the reasonable costs, damages, and legal fees that result, to the extent the claim was caused by you. We will tell you about the claim promptly, let you participate in the defense, and not settle it in a way that makes you admit fault without your consent.

21. Governing law and disputes

Talk to us first. Most problems can be fixed quickly. Before filing any legal claim, you agree to email support@arcavelo.app describing the problem and what you want, and to give us 30 days to try to resolve it informally. We will do the same before bringing a claim against you.

Governing law. These Terms and any dispute arising out of or relating to them or the Service are governed by the laws of the State of Illinois and applicable U.S. federal law, without regard to conflict-of-laws rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

Where disputes are decided. Any dispute that is not resolved informally will be decided exclusively by the state or federal courts located in the State of Illinois, and you and we consent to the personal jurisdiction of those courts. Either of us may instead bring an individual claim in a small-claims court with jurisdiction over it, and either of us may seek an injunction in any court with jurisdiction to protect intellectual property or stop unauthorized access to the Service.

Your consumer rights. If the law where you live gives you the right to bring a claim in your local courts, or gives you consumer protections that cannot be waived by contract, nothing in these Terms takes those rights away.

22. General terms

• Entire agreement. These Terms, together with the documents they incorporate, are the entire agreement between you and us about the Service and replace any earlier agreements about it.
• Assignment. You may not transfer your rights or obligations under these Terms without our written consent. We may transfer ours, including to a business entity formed to operate Arcavelo or to a buyer of the Service, provided the recipient agrees to be bound by these Terms and the Privacy Policy. We will tell you if that happens.
• Severability. If any part of these Terms is found unenforceable, it will be enforced to the maximum extent possible and the rest of the Terms will remain in effect.
• No waiver. If we do not enforce a part of these Terms, that is not a waiver of our right to enforce it later.
• Events outside our control. We are not responsible for delays or failures caused by events beyond our reasonable control, such as outages at our hosting, database, AI, or payment providers, internet failures, natural disasters, or acts of government.
• Electronic communications. You agree that we may communicate with you electronically, by email to the address on your Google account or by notices in the app, and that those communications satisfy any legal requirement that they be in writing.
• Notices to us. Legal notices to us must be sent by email to support@arcavelo.app.
• Relationship. These Terms do not create a partnership, joint venture, employment, or agency relationship between you and us. Except as stated for Apple below, there are no third-party beneficiaries of these Terms.
• Headings. Section headings and the short summary at the top are for convenience only and do not change the meaning of these Terms.
• Apple. If you use an Arcavelo app downloaded from Apple’s App Store, Apple is not a party to these Terms and is not responsible for the app or its content, but Apple and its subsidiaries are third-party beneficiaries of these Terms for that app and may enforce them against you.
