Koyo Terms and Conditions

Last updated: [PUBLICATION DATE]

This is a translation: if it differs from the Spanish version, the Spanish version prevails.

1. What these terms are

These terms are the agreement between you and JOSE CARLOS MARTINEZ DENA, an individual domiciled in Mexico, who develops and operates Koyo ("Koyo", "we", "us").

By creating an account or using Koyo you accept these terms. If you do not agree with them, do not use the app.

How we process your personal data is explained in the Privacy Notice (getkoyo.com/privacy), which is part of these terms.

2. What Koyo is

Koyo is a tool for managing your personal finances. With it you can:

• record your accounts and their balances;
• record income, expenses and transfers between your accounts, by hand, by dictating them to the assistant, by scanning a receipt, or by importing a CSV file;
• organize your transactions into categories;
• create budgets and savings goals;
• see charts and summaries of your money;
• ask the assistant about your finances.

Koyo does not connect to your bank or to any financial institution. It does not move money, does not make payments, does not access your bank accounts, and does not know your real balances: everything it shows comes from what you record.

Koyo is free and shows no ads. If we offer paid features in the future, we will tell you beforehand and their conditions will be added to these terms.

3. Who can use Koyo

To use Koyo you must be over 18 and legally able to accept these terms.

For now, Koyo is available to people in Mexico.

4. Your account

To use Koyo you create an account with your email address and a password. You agree to:

• give an email address that is yours and that you can check, because it is the only way to reset your password;
• keep your password secret and not share your account;
• let us know if you think someone accessed your account without your permission.

If you think someone knows your password, change it: when you do, the other devices where your account was open lose access and can no longer view or save anything in your account. Whatever those devices had stored locally remains visible on them until someone signs out there.

You are responsible for what is done from your account until you let us know about unauthorized access.

You can delete your account at any time from the app, or by requesting it at getkoyo.com/delete-account. Deletion is permanent: it removes your accounts, transactions, categories, budgets, goals and assistant conversations, and it cannot be undone. If you want to keep your history, export your transactions to CSV first.

5. The assistant and receipt scanning

Koyo uses third-party artificial intelligence models for two features: the assistant (chat) and receipt scanning. They are an aid, not a source of truth. They can make mistakes: misread an amount, a date or a currency, pick the wrong category, or misunderstand what you wrote.

The two features record things differently, and you should know how:

• Receipt scanning. Koyo shows you what it read from the receipt on a review screen, and nothing is saved until you confirm it. Check the amount and the currency in particular.
• Assistant. When you dictate a transaction to it ("lunch 200"), the assistant records it right away, without asking you to confirm first, and then tells you what it saved. If something is not what you meant, you can edit or delete it like any other transaction.

In both cases, our server checks that the account and the category exist in your account and confirms exactly what was saved, but the amount is read by the model from what you wrote or photographed. That is why the accuracy of your records is your responsibility: review what the assistant and scanning save for you.

These features cost us money, so they have a daily usage limit. If you reach it, the app tells you and the limit resets the next day. We may adjust that limit to keep the service sustainable.

You may not automate these features, use them from outside the app, or use them for anything other than the normal personal use of Koyo.

6. Koyo is not financial advice

Koyo's figures, charts, budgets and summaries are calculated from what you record and are for information only.

The assistant's answers are generated by an artificial intelligence model. They may include suggestions about how to spend, save or budget, but they are general in nature: the assistant does not know your full situation, can make mistakes, and is not a professional.

Nothing Koyo shows is financial, accounting, tax, investment or legal advice, nor does it replace official information from your bank or the opinion of a professional. Any decisions you make based on Koyo are yours.

7. Your data is yours

What you record in Koyo —your accounts, transactions, categories, budgets, goals and notes— belongs to you. By using Koyo you authorize us only to store it, process it and show it to you in order to provide the service. We acquire no rights over that information and we do not sell it.

You can export your transactions to a CSV file whenever you want, from the app.

Koyo does not review or audit what you record. If you need your records for accounting or tax purposes, keep the original receipts yourself: Koyo does not replace them.

8. Acceptable use

When using Koyo you agree to:

• use it only to manage your personal finances, and for lawful purposes;
• not try to access other people's accounts, data or sessions;
• not try to get around usage limits or security measures;
• not use Koyo in a way that overloads, degrades or disrupts the service for others;
• not use Koyo for fraud, money laundering or any other illegal purpose;
• not copy, modify, decompile or redistribute the app without permission.

If you breach this section, we may suspend or terminate your access (see section 12).

9. Service availability

We do our best to keep Koyo available at all times, but we cannot guarantee that it will work without interruptions or errors. The service may stop because of maintenance, failures at our providers, connection problems, or causes beyond our control.

In the phone app you can view your data and record, edit or delete transactions offline: the changes are sent automatically when the connection comes back. Everything else (accounts, categories, budgets, goals, the assistant, scanning and importing) needs a connection, and the web version does not work without one.

We may change, add or remove features. If a change significantly affects how you use Koyo, we will try to let you know in advance.

10. Liability

Koyo is provided as is and as available. To the extent the law allows, we do not guarantee that the information it shows is free of errors, that the results of the assistant or scanning are accurate, or that the service is fit for any particular purpose.

To the extent the law allows, we are not liable for financial losses, financial decisions, data loss, or indirect damages arising from the use of Koyo or the inability to use it.

Nothing in these terms limits the rights granted to you by Mexico's Federal Consumer Protection Law, nor any liability that the law does not allow to be excluded.

11. Intellectual property

The Koyo app —its code, design, name, logo and texts— belongs to JOSE CARLOS MARTINEZ DENA and is protected by intellectual property laws.

We grant you a personal, limited, non-exclusive, non-transferable and revocable license to use Koyo in accordance with these terms. That license does not transfer to you any rights over the app, its name or its logo.

What you record in Koyo remains yours (section 7).

12. Termination

You can stop using Koyo whenever you want, delete your account and uninstall the app.

We may suspend or terminate your access if you breach these terms, if we detect fraudulent or abusive use, or if an authority requires it. Except in cases of serious abuse or legal requirement, we will warn you beforehand and give you the chance to export your transactions.

The sections on your data, liability and governing law remain in force after termination where applicable.

13. Changes to these terms

We may update these terms. We will publish the new version at getkoyo.com/terms with its update date and, if the change is significant, we will let you know by email before it takes effect. If you keep using Koyo after that date, you accept the updated terms; if you do not agree, you can delete your account.

14. Governing law and disputes

These terms are governed by the laws of the United Mexican States.

If you have a problem with Koyo, write to us first at support@getkoyo.com: most problems are solved that way, and faster. If we cannot reach an agreement, the parties submit to the competent courts of Durango, Mexico, without prejudice to your right to go to Mexico's Federal Consumer Protection Agency (PROFECO).
