Terms of Use

1. The service

Otto is a personal and family money organization app. It brings together data from your accounts and cards, categorizes entries, shows budgets, goals, subscriptions and upcoming payments, and offers an AI assistant to answer questions about your money.

Otto is not a bank, a payment institution or an investment advisory service. It does not move money, make payments or offer credit.

2. Eligibility and account

• Otto is intended for people aged 13 or over. Anyone under 13 may not use it. Users aged 13 to 17 must use it with the knowledge and supervision of their parents or guardians.
• You must provide truthful information and keep access to your account and device secure (we recommend enabling biometrics).
• The account is personal. You are responsible for what happens in it, for what you decide to share with group members and for the integration tokens you create.

3. Open Finance

• Connections to financial institutions use Open Finance Brasil, regulated by Brazil’s Central Bank, through the Malvo aggregator. You give consent at your own institution, choosing which data to share and for how long.
• Access is read-only. Otto never asks for or stores your bank password.
• You can revoke consent at any time, in Otto (by disconnecting the bank) or at your institution.
• Data comes from the institutions and may have delays, failures or discrepancies we do not control. Always check with your bank before important decisions.

4. Notification capture (Android)

This feature is optional. If you turn it on, you authorize Otto to read notifications from the bank apps you choose, from a closed list, to record transactions. Notifications from other apps are discarded on the device. You can turn it off at any time in the device or app settings.

5. Artificial intelligence

• The chat, "Can I spend?", suggestions and categorization are generated automatically by AI from your data, using the providers described in the Privacy Policy.
• Answers are educational and general. They are not financial, accounting, legal or tax advice, nor a recommendation to invest in, buy or sell assets.
• AI can be wrong, misread a question or use outdated data. Check the information and, for relevant decisions, consult a qualified professional.
• You are solely responsible for the financial decisions you make.

6. Groups and sharing

You can invite other people to a group (for example, your partner). Each member decides, account by account, what the others see. Only invite people you trust and review what you share. When you leave a group or delete your account, each member’s own data stays with them.

7. Integrations with AI agents (MCP)

You can create personal tokens to use Otto from other AI assistants. The connected agent accesses your data with the permission you choose (read or write), and its use of that data follows the terms of the service you chose. You can revoke a token at any time in the app.

8. Acceptable use

You agree not to:

• access third-party data without authorization or use accounts that are not yours;
• use Otto for illegal activities, fraud or money laundering;
• try to bypass security, reverse engineer, overload or automate access to the service outside the integrations offered;
• try to make the assistant generate unlawful content or content outside the app’s purpose.

9. Your content

The data and content you add to Otto remain yours. You grant us only the authorization needed to store, process and display them to you and to whoever you choose, for the sole purpose of providing the service, as set out in the Privacy Policy.

10. Intellectual property

The Otto brand, mascot, logo, design, texts and the software of the app and website are protected by law and belong to us or our licensors. These Terms do not transfer any of these rights to you, only a personal, non-exclusive and revocable license to use the app.

11. Plans, subscription and changes

Otto is free to download and use on the Free plan, with no ads. Otto Premium is an optional monthly or yearly subscription that unlocks additional features (such as unlimited banks, notification capture, unlimited "Can I spend?" and chat, couples mode, Otto Kids, all lessons, recurring payment alerts and widgets). The price is shown in the store before purchase.

The subscription is purchased and billed through your device store (Google Play or App Store) and renews automatically at the end of each period until cancelled. The 7-day free trial, when offered, converts into a paid subscription at the end unless cancelled before the trial ends. You can cancel anytime in the store subscriptions; Premium access continues until the end of the period already paid. Refunds follow the store rules and the Brazilian Consumer Protection Code, including the right of withdrawal.

We may add, change or remove features. Changes to prices or to what each plan includes will be announced in advance and only apply to the next period; nothing that is part of the Free plan today will be charged automatically.

12. Availability and limitation of liability

We work to keep Otto available and accurate, but it is provided "as is" and may have interruptions, delays or errors, including due to failures of financial institutions, the aggregator, AI providers or the internet.

To the extent permitted by law, we are not liable for financial decisions made based on the app, for incorrect data provided by third parties or for indirect damages. Nothing in these Terms limits rights you have as a consumer under Brazil’s Consumer Protection Code.

13. Termination and deletion

You can delete your account at any time, in the app (Settings → Privacy and data → Delete my account) or by email. Access is cut off immediately and data is deleted within 30 days, as described on the deletion page.

We may suspend or close accounts that violate these Terms or the law, with notice when possible. We may also discontinue the service, giving reasonable notice and allowing you to download your data.

14. Changes to the Terms

We may update these Terms. Material changes will be announced in the app or by email before they take effect. If you keep using Otto afterwards, you agree to the new version; if you do not agree, you can delete your account.

15. Governing law and jurisdiction

These Terms are governed by the laws of the Federative Republic of Brazil. The courts of the consumer user’s domicile have jurisdiction over any dispute, without prejudice to first seeking an amicable solution through the contact email.
