Terms of Use

What these terms cover

Sensei Top has two parts:

• The app. The desktop app is free software under the GNU Affero General Public License, version 3 (AGPL). The AGPL alone governs how you may use, copy, change and share the software. Nothing in these terms limits your rights under it. Everything the app does on your own computer — reading your logs, your match history, the copy-prompt features — is covered by the AGPL, not by these terms.
• The hosted services. This website (senseitop.com); contributing your games, with or without an account; the account, cloud backup and error reports, in the app; and, once it launches, the rules coach on coach.senseitop.com and in the app. These terms cover the hosted services.

If you use your own Claude key in the app, that use is between you and Anthropic, under your agreement with them, and any cost is charged to your key. It never passes through our services.

How we handle your data is in the Privacy Policy, which is part of these terms.

Free, with no catch

Sensei Top is free. The app, the account and the rules coach cost nothing, and none of them sells your data or shows ads. If we ever offer something paid, it will be optional, we will say so plainly, and nothing will be charged without your yes. A donation is a gift: it buys no feature, no priority and no different terms.

Who can have an account

You must be at least 13 years old. If you are under 18, you need a parent's or guardian's permission to create an account and use the hosted services, and they should read these terms with you. A parent or guardian who gives permission accepts these terms for the child.

You sign in with a Google or Discord account; one verified email address gives one Sensei Top account. Keep it secure; what happens through your signed-in account is your responsibility, unless someone used it without your fault. Tell us at once if you think someone else has used it. One account per person.

The rules coach

Not available yet. Applies once the rules coach launches.

• It is an AI and can be wrong. Every answer carries this line: "AI answer, may be wrong. Check the cited rules; at a tournament, ask a judge." Read the cited rules before you rely on an answer.
• It is not a judge. An answer is not an official ruling. At a tournament, the judge's ruling is the one that counts. Wizards of the Coast does not write, check or endorse the coach's answers.
• What it answers. Magic rules and card interactions, in English. It declines other questions, and a declined question still counts toward your daily limit. A question can be up to 500 characters long.
• Where your question goes. Answers are written by Anthropic's Claude models. Anthropic stores your question in the United States and may process it in other countries. The coach asks you to agree to that the first time you use it; the Privacy Policy explains what is sent.
• Limits. Each player can ask 10 questions a day; the count resets at 00:00 UTC. You may need to wait a few seconds between questions. To keep the coach free, it also has a shared monthly budget: when that budget, or the day's share of it, runs out, the coach pauses for everyone until it resets. We may also pause it at any time to fix a problem. A paused coach does not count your question.
• The limits may change. We may change them, for example after the beta. We will show the current limits in the app and on the website.

Cloud backup

Cloud backup is a convenience, not a guarantee. The database on your computer stays the original; keep it. We do our best to keep your backup safe and available, but the service may be unavailable at times, and we cannot promise it will never lose data.

Contributing your games

Applies only if you say yes to Help build the stats.

Contributing is optional and needs no account. If you say yes:

• You let us use the games you send. We may store them and use them to build Sensei Top's features, as the Privacy Policy describes, without payment to you.
• A sent game cannot be returned or deleted. Nothing in it says it came from you, so we cannot find it again. Your permission for games already sent does not end when you stop contributing or delete your account; stopping means no more games are sent.
• Send only games you played yourself. The app reads them from your own Arena or Magic Online logs; don't point it at anyone else's, or change it to send games it did not read there.
• Age. You must be 13 or older, and if you are under 18, you need a parent's or guardian's permission.

Fair use

Please don't:

• use the hosted services to break the law or harm anyone;
• try to get around the daily limits or the budget, for example with several accounts or automated requests;
• use the coach as a general chatbot, or send it content meant to make it ignore its instructions;
• access the hosted services with scripts or bots, except as the app itself does;
• try to reach another player's data, probe our systems for weaknesses outside SECURITY.md, or overload them;
• send personal information about other people, or anything unlawful or abusive, in a question or a report.

Your content

Your questions, your match history and your reports stay yours. You allow us to store and process them only as needed to run the hosted services, as the Privacy Policy describes. That permission ends when you delete them or your account, except for copies that expire as the Privacy Policy says, and for games you contributed (see "Contributing your games").

The coach's answers are generated for you; you may use them as you like.

Our content and others'

The app's code is ours and its contributors', under the AGPL. The name Sensei Top and its logo are ours.

The Magic: The Gathering rules text, card names and card text belong to Wizards of the Coast. Card data and images come from Scryfall and are shown whole, never cropped. None of these companies produces or endorses Sensei Top.

Sensei Top is unofficial Fan Content permitted under the Fan Content Policy. Not approved/endorsed by Wizards. Portions of the materials used are property of Wizards of the Coast. ©Wizards of the Coast LLC.

Changes, pauses and ending the service

The hosted services are free and run by one person, so they may change. We may add, change or remove features, and we may stop a hosted service. If we stop the account or cloud backup, we will tell signed-in players at least 30 days in advance, so you can export your data first. The app keeps working on your computer either way.

You can stop using the hosted services and delete your account at any time. We may suspend or close an account that seriously or repeatedly breaks these terms. Where we can, we will tell you why first and give you a chance to export your data.

No warranties, to the extent the law allows

We build Sensei Top with care, but we provide the hosted services "as they are" and "as available". To the extent the law allows, we do not promise that they will always be available, free of errors, or right for your purpose, or that a coach answer is correct.

Liability, to the extent the law allows

To the extent the law allows, we are not liable for indirect losses, such as a game, match or tournament lost because of a coach answer, or data you did not keep on your own computer.

Nothing in these terms limits any right you have as a consumer that the law does not allow to be limited, including your rights under Brazil's Consumer Defense Code (Código de Defesa do Consumidor) and the mandatory consumer law of the country where you live. Nothing limits liability for fraud, wilful misconduct or gross negligence.

Changes to these terms

When these terms change, we change the date at the top. If a change matters to you, we tell signed-in players in the app or by email before it applies; if you do not agree, you can export your data and delete your account.

Law and disputes

Brazilian law governs these terms, and Brazilian courts decide disputes about them. If you are a consumer in Brazil, you may bring a claim in the courts where you live. If you live elsewhere, you also keep the protection of the mandatory consumer law of your country and may use its courts where that law allows.

Please write to us first. Most problems are faster to solve by email.
