5. Do We Use Cookies and Other Tracking Technologies?

In Short: We may use cookies and other tracking technologies to collect and store your information.

We use cookies and similar tracking technologies to maintain the security of our Services and your account, prevent crashes, fix bugs, save your preferences, and assist with basic site functions.

Currently, our Services use only essential cookies (session management, authentication tokens, language preferences). These cookies are strictly necessary for the operation of the Services and do not require your consent under the ePrivacy Directive. They are described below:

  • Session cookie — maintains your authenticated session while using the Services.
  • Authentication token — verifies your identity across requests.
  • Language preference — stores your selected interface language.

We do not use third-party advertising cookies or cross-site tracking technologies. If we introduce non-essential cookies (such as analytics) in the future, we will update this notice and implement an appropriate consent mechanism.

6. Do We Offer Artificial Intelligence-Based Products?

In Short: We offer products, features, or tools powered by artificial intelligence, machine learning, or similar technologies.

As part of our Services, we offer products, features, or tools powered by artificial intelligence, machine learning, or similar technologies (collectively, "AI Products").

Use of AI Technologies

We provide the AI Products through third-party service providers ("AI Service Providers"), including Anthropic (for response generation via Claude API), OpenAI (for text embedding and semantic search), and Cohere (for search result ranking). As outlined in this Privacy Notice, your input, output, and personal information will be shared with and processed by these AI Service Providers to enable your use of our AI Products for purposes outlined in "What Legal Bases Do We Rely On to Process Your Personal Information?" above. You must not use the AI Products in any way that violates the terms or policies of any AI Service Provider.

Our AI Products

Our AI Products are designed for the following functions:

  • Legal information retrieval and synthesis

How We Process Your Data Using AI

All personal information processed using our AI Products is handled in line with our Privacy Notice and our agreements with third parties. This ensures high security and safeguards your personal information throughout the process.

Automated Decision-Making

Our AI Products generate informational responses to your legal questions. These responses are informational only and do not constitute automated decision-making with legal or similarly significant effects as described in GDPR Article 22. The AI does not make decisions about your legal rights, obligations, or status — it provides information to help you make your own informed decisions.

7. How Do We Handle Your Social Logins?

In Short: If you choose to register or log in to our Services using a third-party account, we may have access to certain information about you.

Our Services offer you the ability to register and log in using your third-party account details (Google, Apple, or Telegram). Where you choose to do this, we will receive certain profile information about you from the provider. The profile information we receive may vary depending on the provider concerned, but will typically include your name, email address, and profile picture (where applicable).

We will use the information we receive only for the purposes that are described in this Privacy Notice or that are otherwise made clear to you on the relevant Services. Please note that we do not control, and are not responsible for, other uses of your personal information by your third-party provider. We recommend that you review their privacy notice to understand how they collect, use, and share your personal information, and how you can set your privacy preferences on their sites and apps.

8. Is Your Information Transferred Internationally?

In Short: We may transfer, store, and process your information in countries other than your own.

Our servers are located in Germany (EU). Regardless of your location, please be aware that your information may be transferred to, stored by, and processed by us in our facilities and in the facilities of the third parties with whom we may share your personal information (see "When and With Whom Do We Share Your Personal Information?" above), including facilities in Canada (Cohere), the United States (Anthropic, OpenAI, Google, Apple, Stripe), and other countries.

If you are a resident in the European Economic Area (EEA), United Kingdom (UK), or Switzerland, then these countries may not necessarily have data protection laws or other similar laws as comprehensive as those in your country. However, we will take all necessary measures to protect your personal information in accordance with this Privacy Notice and applicable law.

European Commission's Standard Contractual Clauses:

We have implemented measures to protect your personal information, including by using the European Commission's Standard Contractual Clauses for transfers of personal information between us and our third-party providers. These clauses require all recipients to protect all personal information that they process originating from the EEA or UK in accordance with European data protection laws and regulations. Our Data Processing Agreements that include Standard Contractual Clauses are available here: https://www.anthropic.com/policies/commercial-terms. We have implemented similar appropriate safeguards with our third-party service providers and partners and further details can be provided upon request.

9. How Long Do We Keep Your Information?

In Short: We keep your information for as long as necessary to fulfill the purposes outlined in this Privacy Notice unless otherwise required by law.

We will only keep your personal information for as long as it is necessary for the purposes set out in this Privacy Notice, unless a longer retention period is required or permitted by law (such as tax, accounting, or other legal requirements).

Our general retention periods are as follows:

  • Account data (name, email, authentication data) — retained while your account is active, plus one (1) month after account termination to allow for reactivation or data export requests.
  • Chat history (messages and AI responses) — retained while your account is active. You may delete individual conversations at any time.
  • Uploaded images — retained while your account is active or until you delete them.
  • Payment transaction records — retained for up to 10 years in compliance with Portuguese tax legislation (see Data Retention Exceptions).
  • Server logs — retained for up to 90 days for security and troubleshooting purposes.
  • AI provider logs (on Anthropic's side) — retained for up to 7 days for safety and abuse monitoring, then automatically deleted.

When we have no ongoing legitimate business need to process your personal information, we will either delete or anonymize such information, or, if this is not possible (for example, because your personal information has been stored in backup archives), then we will securely store your personal information and isolate it from any further processing until deletion is possible.

10. How Do We Keep Your Information Safe?

In Short: We aim to protect your personal information through a system of organizational and technical security measures.

We have implemented appropriate and reasonable technical and organizational security measures designed to protect the security of any personal information we process. However, despite our safeguards and efforts to secure your information, no electronic transmission over the Internet or information storage technology can be guaranteed to be 100% secure, so we cannot promise or guarantee that hackers, cybercriminals, or other unauthorized third parties will not be able to defeat our security and improperly collect, access, steal, or modify your information. Although we will do our best to protect your personal information, transmission of personal information to and from our Services is at your own risk. You should only access the Services within a secure environment.

11. Do We Collect Information From Minors?

In Short: We do not knowingly collect data from or market to children under 18 years of age.

We do not knowingly collect, solicit data from, or market to children under 18 years of age, nor do we knowingly sell such personal information. By using the Services, you represent that you are at least 18 or that you are the parent or guardian of such a minor and consent to such minor dependent's use of the Services. If we learn that personal information from users less than 18 years of age has been collected, we will deactivate the account and take reasonable measures to promptly delete such data from our records. If you become aware of any data we may have collected from children under age 18, please contact us at privacy@omnixal.com.

12. What Are Your Privacy Rights?

In Short: In some regions, such as the European Economic Area (EEA), United Kingdom (UK), and Switzerland, you have rights that allow you greater access to and control over your personal information. You may review, change, or terminate your account at any time, depending on your country, province, or state of residence.

In some regions (like the EEA, UK, and Switzerland), you have certain rights under applicable data protection laws. These may include the right:

  1. To request access and obtain a copy of your personal information (Art. 15 GDPR)
  2. To request rectification of inaccurate personal information (Art. 16 GDPR)
  3. To request erasure of your personal information (Art. 17 GDPR)

  6. To object to the processing of your personal information (Art. 21 GDPR)
  7. Not to be subject to automated decision-making, including profiling (Art. 22 GDPR)

In certain circumstances, you may also have the right to object to the processing of your personal information. You can make such a request by contacting us by using the contact details provided in the section "How Can You Contact Us About This Notice?" below.

We will consider and act upon any request in accordance with applicable data protection laws.

If you are located in the EEA or UK and you believe we are unlawfully processing your personal information, you also have the right to complain to your Member State data protection authority or UK data protection authority. If you are located in Portugal, you may contact the Comissão Nacional de Proteção de Dados (CNPD).

If you are located in Switzerland, you may contact the Federal Data Protection and Information Commissioner.

If we are relying on your consent to process your personal information, you have the right to withdraw your consent at any time. You can withdraw your consent at any time by contacting us by using the contact details provided in the section "How Can You Contact Us About This Notice?" below or updating your preferences.

However, please note that this will not affect the lawfulness of the processing before its withdrawal nor will it affect the processing of your personal information conducted in reliance on lawful processing grounds other than consent.

Opting out of marketing and promotional communications

You can unsubscribe from our marketing and promotional communications at any time by clicking on the unsubscribe link in the emails that we send, managing newsletter subscription preferences in account settings, or by contacting us using the details provided in the section "How Can You Contact Us About This Notice?" below. You will then be removed from the marketing lists. However, we may still communicate with you — for example, to send you service-related messages that are necessary for the administration and use of your account, to respond to service requests, or for other non-marketing purposes.

Account Information

If you would at any time like to review or change the information in your account or terminate your account, you can:

  • Log in to your account settings and update your user account.
  • Contact us using the contact information provided.

Upon your request to terminate your account, we will deactivate or delete your account and information from our active databases. However, we may retain some information in our files to prevent fraud, troubleshoot problems, assist with any investigations, enforce our legal terms and/or comply with applicable legal requirements.

Cookies and similar technologies: Most Web browsers are set to accept cookies by default. If you prefer, you can usually choose to set your browser to remove cookies and to reject cookies. If you choose to remove cookies or reject cookies, this could affect certain features or services of our Services.

Data export: You may request an export of your personal data in a machine-readable format (JSON) by contacting us at privacy@omnixal.com. We will fulfill such requests within 30 days.

If you have questions or comments about your privacy rights, you may email us at privacy@omnixal.com.

13. Controls for Do-Not-Track Features

Most web browsers and some mobile operating systems and mobile applications include a Do-Not-Track ("DNT") feature or setting you can activate to signal your privacy preference not to have data about your online browsing activities monitored and collected. At this stage, no uniform technology standard for recognizing and implementing DNT signals has been finalized. As such, we do not currently respond to DNT browser signals or any other mechanism that automatically communicates your choice not to be tracked online. If a standard for online tracking is adopted that we must follow in the future, we will inform you about that practice in a revised version of this Privacy Notice.

14. AI Data Processing and Third-Party AI Providers

When you use our Service, your messages and any uploaded images are transmitted to third-party AI providers for the purpose of generating responses. Specifically:

  • Anthropic (Claude API) — receives your messages and conversation context to generate legal information responses. Anthropic retains API logs for up to 7 days for safety and abuse monitoring purposes, after which they are automatically deleted. Anthropic does not use API data for model training.
  • OpenAI — receives text queries (typically without personally identifiable information) for the purpose of generating text embeddings used in semantic search. OpenAI does not use API data for model training.
  • Cohere — receives search results for the purpose of ranking relevance. Cohere does not retain query data beyond the duration of the request.

AI providers process your data solely to deliver responses and do not use it for training their models. We recommend that you do not share sensitive personal information (such as tax identification numbers, financial details, or health information) in your messages unless necessary for your query.

15. Data Retention Exceptions

Notwithstanding our general retention policy described in section 9, certain data may be retained for longer periods as required by law:

  • Payment transaction records and invoicing data are retained for up to 10 years in compliance with Portuguese tax legislation (Código do IRS, Código do IRC, Lei Geral Tributária).
  • Data that has been anonymized or aggregated for service improvement purposes may be retained indefinitely as it no longer constitutes personal data under GDPR.
  • Data required for ongoing legal proceedings or regulatory investigations will be retained for the duration of such proceedings.

16. Do We Make Updates to This Notice?

In Short: Yes, we will update this notice as necessary to stay compliant with relevant laws.

We may update this Privacy Notice from time to time. The updated version will be indicated by an updated "Last updated" date at the top of this Privacy Notice. If we make material changes to this Privacy Notice, we may notify you either by prominently posting a notice of such changes or by directly sending you a notification. We encourage you to review this Privacy Notice frequently to be informed of how we are protecting your information.

You have the right to request access to the personal information we collect from you, details about how we have processed it, correct inaccuracies, or delete your personal information.
