Terms of Use

Last updated: October 10, 2026

This is a translation. In case of discrepancy, the Portuguese version prevails. Read the original in Portuguese.

By using the Theros app, you agree to the terms and conditions described below. Please read them carefully before using the app.

1. Acceptance of the Terms

By creating an account, accessing or using Theros, you represent that you:

If you do not agree with any provision of these terms, do not use the app.

2. Description of the Service

Theros is a personal finance management and productivity app that offers:

3. Registration and Account

3.1 Requirements

3.2 Account security

4. Plans and Subscription

4.1 Available plans

Theros offers different levels of access:

Plan Features
Free Basic financial management features with AI usage limits
Essential Expanded features with a larger AI quota
Pro Full access including voice chat, scheduled agents and Gmail integration
Premium Full access with maximum usage limits

4.2 Payment and renewal

4.3 Cancellation and refunds

4.4 AI usage limits

Each plan includes a monthly AI usage allowance, which may be measured in tokens (the unit in which AI models read and write text) or in another unit indicated in the app, in addition to daily and per-feature limits (for example, web search, photo analysis and voice chat), to protect the stability of the service. As a result:

The prices of each plan and the quantities above may be adjusted under the terms of section 23.

4.5 Usage bonuses and friend referrals

Theros may grant AI usage bonuses (for example, for referring friends, campaigns or courtesies) and trial periods. Unless the offer states otherwise:

To prevent repeated use of benefits, we keep only an irreversible code (hash) of the verified phone number and of the random app installation identifier, in accordance with the Privacy Policy.

5. Acceptable Use

You agree to use Theros only for personal and lawful purposes. The following is expressly prohibited:

Fair use. It is also prohibited to use the service in a way that generates abnormal resource consumption, such as automating mass calls, attempting to circumvent limits, reselling access, creating multiple accounts to obtain bonuses or free trial periods, or sending content of extraordinary size. In case of abuse, we may apply additional limits, pause the AI feature or terminate the account, under the terms of section 18.2.

6. Artificial Intelligence

6.1 Nature of the responses

The Theros AI assistant (text chatbot, voice commands and voice chat) uses artificial intelligence models, primarily Google Gemini, to provide financial suggestions and insights. AI responses are for informational purposes only and do not constitute professional financial, legal, accounting or investment advice.

6.2 Limitations and responsibilities

6.3 Use of data by the AI

To generate contextualized responses, Theros sends the content of your conversation and the necessary context (for example, a summary of the data you have already recorded in the app, such as transactions, budgets and goals) to artificial intelligence processors engaged by us. The main one is Google (Gemini, via Google Cloud Vertex AI); for general text conversations, Theros may also use other model providers, including through intermediaries, in accordance with section 5.9 of the Privacy Policy. Health data, documents and photos are only processed under the conditions described in that section. We choose the most suitable model and processor for each task and may change them without individual notice, while maintaining the data protection rules of the Policy.

Data is sent to generate the requested response. We do not use your content to train our own AI models and we select processors and configurations that, according to their terms, do not use content received through the API for training. Some processors may keep temporary copies for a limited period, for security and abuse detection, in accordance with their own rules. For more details, see the Privacy Policy.

6.4 Voice chat

6.5 Health, nutrition and well-being
