Terms of Use

Last updated: 10/07/2026 · Portuguese is the official, authoritative version.

In short

Compendium is currently a free beta with no paid plans. These Terms govern use of the app today. When paid plans launch, we will publish the corresponding commercial terms (payment, subscription, and cancellation) before any charge.

Provider: Vitor Pio Daldegan (natural person, CNPJ not yet registered). Contact: askcompendium@gmail.com.

1. What Compendium Is

Compendium is a methodological support tool for systematic reviews and meta-analysis. It assists, but does not replace, scientific judgment and human review. It does not provide medical, clinical, or health-advice services, and its outputs do not constitute clinical recommendations.

2. Free Beta, Provided "As Is"

The app is made available free of charge, in development, as is, without warranties of any kind, including no warranty of scientific accuracy. You are solely responsible for verifying every result against primary sources.

3. Local AI and Human in the Loop

By default, the AI runs on your own device and your content does not leave the machine. The AI abstains rather than guesses, and never decides on its own whether to include or exclude a study. We recommend disclosing the use of AI when reporting your study, in line with good scientific practice.

4. Your Data and Outputs Are Yours

You retain ownership of the content you enter and of the outputs generated (protocols, reports, charts). You agree not to enter identifiable personal data of patients or research participants. This restriction also applies to any message you send us for support purposes (e.g. by email): do not include identifiable patient or research-participant data there either. The processing of personal data will follow our Privacy Policy.

If you publish results produced with Compendium, such as a paper, report, or presentation, we ask that you cite the software using the citation the app itself provides (in Settings or on the export screen). This is a professional courtesy in line with how any analysis software is credited in academic work, not a restriction on your ownership of the outputs described above.

5. Acceptable Use

You agree not to use Compendium for unlawful purposes, not to attempt to compromise its security, and not to resell or sublicense access without authorization.

6. Limitation of Liability

To the maximum extent permitted by law, we are not liable for indirect damages, data loss, or losses arising from scientific decisions made based on the app. Nothing in these Terms removes rights the law grants to consumers.

7. Provider, Governing Law, and Contact

Vitor Pio Daldegan (natural person, CNPJ not yet registered). Contact: askcompendium@gmail.com. These Terms are governed by the laws of the Federative Republic of Brazil, with venue at the comarca of Campinas/SP, except where a jurisdiction rule favoring the consumer applies. Nothing in these Terms deprives the consumer of the protection of the mandatory rules of their country of habitual residence; consumers resident in the European Union/EEA or the United Kingdom may bring proceedings in their local courts and invoke the mandatory consumer protections of their country.

This is the version of the Terms in force for the current phase of the product (free beta, no paid plans, no billing). When paid plans, cloud features, or other material changes launch, we will update this page beforehand and have it reviewed by a Brazilian lawyer experienced in the LGPD, the Marco Civil da Internet, and the Consumer Protection Code.
