Terms of Use

Some parts of the site may be accessed without an account, but saving documents, syncing a workspace, using authenticated features, accessing plan limits, and purchasing subscriptions require registration. During registration, acceptance of these Terms supports the data processing needed to operate the authenticated service.

This acceptance is not unlimited permission for any marketing tracking or non-essential collection. Telemetry, cookies, analytics, and observability follow the Privacy Policy and the governance rule applicable to anonymous or authenticated state.

You are responsible for keeping credentials secure, using accurate information, and notifying us if you notice unauthorized account access.

You retain the rights to texts, documents, notes, files, and other content you create or upload. This does not transfer ownership of your content to Zerus. You authorize us to process it only as needed to save, edit, convert, export, share, protect, and deliver the features you request.

The interface, brand, code, design, flows, public documentation, and components of Zerus belong to the product or its licensors and are protected by intellectual property laws.

You must not use the platform to violate laws, third-party rights, privacy, intellectual property, security systems, antifraud policies, or the product's technical limits. You must not bypass access controls or quotas, extract data by unauthorized means, interfere with the service, or reverse engineer it, except where applicable law expressly permits.

You must not use converters, link transcription, OCR, AI, or any platform feature for piracy, plagiarism, unauthorized reproduction, improper redistribution, or content that violates copyright, publicity rights, third-party platform terms, or permissions from the original creator.

We may limit, suspend, or terminate access in cases of abuse, security risk, attempts to bypass plan or rate limits, improper automation, illegal content, or breach of these Terms.

AI, OCR, transcription, conversion, summary, translation, SEO, and workspace-question features may send prompts, documents, notes, preferences, files, or content excerpts to external providers in the categories described in the Privacy Policy. This occurs according to the feature you use; those providers may apply their own terms, policies, and retention periods.

When transcribing links, audio, video, images, or PDFs, you represent that you have the necessary rights or creator authorization to process the content and use the resulting text. Commercial use of transcribed text requires an appropriate license, ownership, or permission.

AI or converter outputs may include errors, omissions, incorrect interpretations, formatting loss, or content unsuitable for your purpose, and may not be unique. You must review the output and confirm that you have the necessary rights before publishing, sending, signing, filing, or making decisions based on it. These features do not replace professional advice.

Do not enter highly sensitive data, trade secrets, credentials, or critical medical, legal, or financial information when you cannot accept the processing needed for the selected feature.

The product depends on external providers for authentication, hosting, payments, email, analytics, security, and features you request. The Privacy Policy describes these categories, purposes, data involved, and possible international transfers.

Payments, checkout, subscription management, and billing communications are handled by payment providers. The plan, price, currency, billing interval, applicable taxes, and conditions shown before confirmation form part of the offer you accept.

When you request email sharing, such as weekly agenda sharing, sender data, recipient data, content, and generated attachments may be sent through related email and processing providers.

When automatic renewal applies, checkout shows the price and billing interval before purchase. You can cancel renewal under Settings > Subscription; cancellation stops future charges and generally keeps access until the end of the paid period. Cancellation is distinct from any statutory right to withdraw.

For online purchases, you may exercise any applicable statutory right to withdraw within the period set by law. Settings > Subscription provides a flow to request immediate cancellation and a refund of the initial charge within the seven-day window shown in the product. If automatic processing does not complete, the request is referred for review. These flows do not limit statutory rights; contact us below if you cannot use them.

We may apply quotas, rate limits, abuse blocks, and plan gating in both frontend and backend. Attempts to bypass these controls may result in suspension.

The Privacy Policy explains which data we process, for which purposes, with which third parties, for how long in general terms, and which rights may be requested. These Terms incorporate that Policy by reference.

Account settings let you export data and register an account deletion request. Registering a request starts operational handling but does not mean immediate erasure from every system or provider. Some data may be retained where there is a legal basis or documented need, as explained in the Privacy Policy.

Questions, complaints, and disputes related to personal data, telemetry, or third-party use also follow the contact channel below, with the option to request a formal review in the same thread.

The platform is provided "as available". Interruptions, errors, incompatibilities, or feature changes may occur. We do not promise unlimited history preservation or suitability for a specific professional purpose; keep copies of important content and review tool outputs.

Nothing in these Terms excludes or reduces responsibilities or rights that cannot be limited under applicable law, including consumer and data protection rights. To the extent permitted by law, Zerus is not responsible for harm caused by use contrary to these Terms or by content and instructions supplied by the user.

We may update these Terms to reflect changes to the product, offer, or law. The current version and its update date will appear on this page; material changes will be communicated through appropriate means when required or necessary. Where the law requires renewed acceptance, use of affected features will depend on that confirmation.

These Terms are governed by the laws of Brazil, subject to mandatory consumer protection and data protection rules that apply. Nothing in this clause removes any forum or rights granted to you by law.
