Terms of Use

1. Acceptance and scope

These Terms govern access to and use of VIERLO, an AI workspace for individuals and organizations. By creating an account, accepting an invitation, purchasing a subscription, or using the service, you agree to these Terms and the Privacy Policy. If you use VIERLO for an organization, you confirm that you have authority to bind it. Mandatory rights under applicable consumer and data-protection law remain unaffected.

2. Eligibility and accurate information

You must have legal capacity to enter into these Terms. The service is not directed to children. If applicable law permits use by a minor only with authorization, a parent or legal representative must provide and supervise that authorization. Registration, billing, company, and contact information must be accurate and kept current.

3. Accounts, credentials, and workspaces

VIERLO supports individual e-mail/password accounts and authorized company access using Company + Access Key. Access Keys are enterprise credentials, not shared personal passwords. You must protect passwords, Access Keys, recovery codes, sessions, and connected integrations; use strong authentication; and promptly report suspected compromise.

Each person in a Business workspace should use an individual account where available. Owners and authorized administrators may manage members, roles, workspace settings, content, security events, and plan limits. Users must only access workspaces and data for which they have permission. VIERLO may suspend or revoke credentials that are exposed, abused, inactive, or present a security risk.

4. Plans, usage, and member limits

Features, usage allowances, storage, document and image capacity, and member limits depend on the plan shown before purchase or established in a direct contract. Current standard Business member limits are enforced by the backend. Usage measurements may reasonably account for requests, tokens, storage, documents, images, members, and abusive or automated traffic. Limits are not a promise of uninterrupted or unlimited availability.

5. Subscriptions, billing, and taxes

Online subscriptions are processed through Paddle or another provider identified at checkout. The authorized price, billing interval, currency, taxes, renewal terms, and plan are displayed before confirmation. Payment-card details are handled by the payment provider and are not stored by VIERLO. You authorize recurring charges until cancellation, subject to the checkout terms and applicable law.

Cancellation stops future renewals and ordinarily preserves access through the paid period. Failed payments may cause restriction or suspension after reasonable handling. Refunds, withdrawal rights, duplicate charges, and direct contracts are governed by the Cancellation and Refund Policy, the payment provider rules, the applicable contract, and non-waivable law. VIERLO will not silently cancel a Paddle subscription when an account is deleted.

6. License to use VIERLO

Subject to these Terms and payment when required, VIERLO grants you a limited, non-exclusive, non-transferable, revocable right to use the service for lawful personal or internal business purposes. No source code, model weights, trade secrets, trademarks, or other intellectual property are transferred to you. You may not resell, copy, reverse engineer, scrape, benchmark for publication without authorization, evade technical controls, or use the service to build a competing model or service except where law expressly permits.

7. Your content and permissions

You retain the rights you hold in prompts, files, projects, documents, images, memories, integration data, and other content submitted to VIERLO. You grant VIERLO and its contracted processors only the rights reasonably necessary to host, transmit, transform, index, retrieve, back up, and process that content to provide, secure, support, and maintain the requested features.

You represent that you have the necessary rights and lawful basis to submit the content. Do not submit secrets, special-category data, confidential third-party material, or regulated information unless your use is authorized and the selected feature and contract are appropriate. Workspace administrators may be able to access or manage organizational content under the organization’s policies.

8. AI features and human review

VIERLO Intelligence produces probabilistic output. Responses may be incomplete, outdated, inaccurate, or unsuitable for a particular purpose. Output is not professional legal, medical, financial, accounting, employment, or security advice and must not replace qualified review. You are responsible for checking facts, sources, code, permissions, and consequences before relying on or publishing output.

Do not use output as the sole basis for decisions that produce legal or similarly significant effects on a person. Research, tools, agents, automations, and integrations only perform actions when the relevant capability is available and authorized; an answer does not itself prove that an external action occurred. Similar output may be generated for other users, and VIERLO does not guarantee that output is unique or eligible for intellectual-property protection.

9. Acceptable use

You must not use VIERLO to:

• violate law, court orders, contractual duties, privacy, intellectual-property, publicity, or other rights;
• access another user or organization, bypass authentication, probe vulnerabilities without authorization, or obtain secrets or restricted data;
• distribute malware, phishing, spam, fraudulent content, harmful code, or instructions intended to cause unlawful harm;
• upload executable or disguised files, interfere with availability, overload systems, evade rate or plan limits, or automate abusive requests;
• impersonate a person or organization, misrepresent AI output as verified fact, or falsely state that VIERLO performed an action;
• process personal data unlawfully, conduct prohibited discrimination, surveillance, or high-risk profiling, or expose confidential information;
• use the service for exploitation of children, violent wrongdoing, or any content or conduct prohibited by applicable provider policies.

10. Files, research, integrations, and automations

Uploads are subject to type, size, ownership, security, and retention controls. Temporary chat images may expire and become unavailable while the surrounding textual conversation remains. External websites and documents may contain inaccurate or malicious instructions; they do not override permissions or authorize disclosure of secrets.

Third-party integrations are governed by their own terms and permissions. You must confirm the target and scope before actions that write, send, delete, publish, charge, or otherwise affect external systems. You may disconnect integrations, but the provider may retain data under its own policy. Scheduled or background actions are not guaranteed unless the interface confirms that the required infrastructure and authorization are active.

11. Intellectual property and feedback

VIERLO, its software, interfaces, branding, documentation, and service-generated telemetry are protected by applicable intellectual-property law. If you voluntarily submit product feedback or ideas, you grant VIERLO a worldwide, perpetual, irrevocable, royalty-free right to use them to operate and improve the service, without identifying you publicly or overriding rights in your separate workspace content.

12. Third-party services

VIERLO relies on infrastructure, database, AI, e-mail, payment, and integration providers. Their systems, content, and availability are outside VIERLO’s exclusive control. Links and integrations do not constitute endorsement. Your use of a third-party service may require a separate account and acceptance of that provider’s terms.

13. Availability, changes, and beta features

We work to provide a reliable service but do not guarantee uninterrupted, error-free, or permanently available operation. Maintenance, security incidents, provider failures, rate limits, internet conditions, and force-majeure events may affect availability. Features may be improved, replaced, restricted, or discontinued with reasonable notice where practicable. Features identified as beta, preview, test, or coming soon may be incomplete and should not be used for critical production decisions.

14. Suspension, termination, and data access

You may stop using VIERLO and request account closure through available settings or support. We may restrict or suspend access when reasonably necessary for security, legal compliance, non-payment, material breach, abuse, or protection of users and infrastructure. Where appropriate, we will provide notice and an opportunity to remedy.

Before closure, export available data where needed. Deletion is subject to technical processing time, backups, legal retention, fraud prevention, financial records, security logs, and organization-level ownership. An organization may retain its workspace content after an individual member leaves. Provisions intended by their nature to survive termination remain effective.

15. Disclaimers

To the maximum extent permitted by law, VIERLO is provided on an “as available” basis without implied warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, or uninterrupted availability. This does not exclude warranties, remedies, or liabilities that cannot lawfully be limited, including mandatory consumer rights.

16. Limitation of liability

To the maximum extent permitted by law, VIERLO will not be liable for indirect, incidental, special, punitive, or consequential loss; loss of profits, revenue, goodwill, business opportunity, or data; or decisions made without appropriate human verification. For paid services, aggregate contractual liability will not exceed the amounts paid for the affected service during the twelve months preceding the event, unless applicable law requires a different result. Nothing limits liability for fraud, willful misconduct, gross negligence, personal injury, or other liability that cannot legally be limited.

17. Responsibility for business use

Organizations are responsible for their members, permissions, lawful instructions, connected systems, and internal policies. To the extent permitted by law, a business user will defend and indemnify VIERLO from third-party claims caused by its unlawful content, infringement, unauthorized data processing, or material breach of these Terms. This section does not apply where prohibited by consumer law or to the extent VIERLO caused the claim.

18. Governing law and disputes

These Terms are governed by the laws applicable in Brazil, including mandatory consumer and data-protection rules where relevant. Before formal proceedings, the parties should attempt good-faith resolution through VIERLO support. Any choice of venue is subject to mandatory law, including a consumer’s right to use the competent court available under applicable legislation.

19. Changes, notices, and severability

Material changes will be identified by a new version and effective date and may require renewed acceptance. Notices may be delivered in the service or to the verified account e-mail. If a provision is unenforceable, it will be limited to the minimum necessary and the remaining provisions continue. Failure to enforce a provision is not a waiver. These Terms, the Privacy Policy, the Cancellation and Refund Policy, checkout terms, and any signed direct contract form the applicable agreement; a signed contract controls to the extent of a direct conflict.

20. Contact

Questions, legal notices, and support requests may be submitted through the authenticated Feedback & Ideas area. Do not include passwords, Access Keys, payment-card details, API keys, or other secrets in a request.
