Terms of Use
These Terms govern the website and the purchase of Nyv Sentinel. Publishing the plans does not, by itself, open sign-up or checkout: those capabilities become available only when they are expressly enabled in the authorized environment.
This is an English translation of version 2026-08-12.sentinel-web-v1. The Portuguese text is the one accepted at sign-up and prevails if the two differ. It covers the offer currently available in Brazil, billed in Brazilian reais; terms for US-dollar plans will be published before US-dollar billing opens. Ler em português.
Identification of the provider
The website and Nyv Sentinel are provided by NYV IQ TECNOLOGIA LTDA, trade name Nyv IQ, CNPJ (Brazilian company registration) 68.508.081/0001-79, municipal registration 4483251, located at Rua Pais Leme, 215, Conjunto 1713 - Pinheiros, São Paulo/SP - CEP 05424-150. The electronic channels are contato@nyviq.com, privacidade@nyviq.com and the contact form.
1. Acceptance, version and copy
By checking the acceptance box and completing an authorized sign-up, the customer declares that they have the capacity to act on their own behalf or to represent the company provided, and accepts these Terms and the Privacy Policy. The acceptance record links the version above to the date, time and technical reference of the request. This page can be printed or saved as a PDF to keep a copy before accepting. The static copy of this version (in Portuguese) also remains available at its own address. Future changes require a new version and do not erase the previous record.
2. Scope of Nyv Sentinel
Sentinel follows the product addresses registered by the customer, compares the available signals, organizes evidence and sends alerts through the channels included in the plan. The service does not change prices, stock, listings, catalogs or store settings, does not buy products and does not make business decisions on the customer's behalf. The customer must check the evidence and remains responsible for prices, margins, stock, listings and other decisions of their own business.
3. Plans, capacity and prices
The Sentinel offer uses explicit limits on active products and scheduled frequencies. A source outage, technical limitation, maintenance, retry or security measure may delay a check, as described in section 12.
Início: up to 20 active products; checks scheduled every 6 hours; alerts by email; recurring monthly at R$49.00 or prepaid annual at R$470.00.
Pro: up to 50 active products; checks scheduled every 3 hours; alerts by email and WhatsApp; recurring monthly at R$97.00 or prepaid annual at R$931.00.
Escala: up to 100 active products; checks scheduled every 3 hours, with up to 10 priority products every hour; alerts by email and WhatsApp; recurring monthly at R$197.00 or prepaid annual at R$1,891.00.
4. Free trial
When public sign-up is enabled, the trial lasts 14 consecutive days, with no card required and no automatic conversion into a subscription. The period starts when the account is activated. At the end, monitoring may be suspended if the customer does not choose a plan and confirm payment at checkout. The trial, by itself, does not authorize any charge.
5. Payment method and renewal
When billing is formally enabled, payment will be made in Brazilian reais by card on Stripe's hosted checkout. Nyv IQ does not store the full card number. The monthly plan renews every month until canceled. The annual plan is a single upfront payment for a 12-month period, with no automatic renewal; a new annual period requires a new authorization from the customer. The total, the plan and the billing cycle will be shown for review before confirmation. Other payment methods may only be offered after their enablement is proven and the offer is clearly updated.
6. Tax invoice
The NFS-e (Brazilian electronic service invoice) will be issued by NYV IQ TECNOLOGIA LTDA, when due, according to applicable law, the service purchased and the tax data provided by the customer. The customer must keep the corporate name, CNPJ or CPF and address correct when this information is needed. A Stripe receipt, invoice or proof of payment does not replace the NFS-e.
7. Failed payment, default and suspension
If a monthly charge fails, the subscription may remain pending while Stripe makes the configured retries. The billing status will be available in the account area, and the customer can update the payment method through the processor's portal. If the default continues, monitoring and the purchased access may be suspended or terminated. Confirmed settlement may restore access, subject to the plan, security and operational availability. There are no recurring charges on the annual plan.
8. Cancellation
The monthly plan can be canceled before the next renewal through the Nyv IQ account area or the support channel. The processor's portal can be used to view invoices and update the payment method, but it does not replace Nyv IQ's cancellation flow with a reference number. There will be no further renewal after cancellation, and access remains until the end of the monthly period already paid, except in cases of fraud, abuse or legal obligation. The annual plan does not renew automatically and remains available until the end of the 12 months paid. The request receives electronic confirmation and a reference number. Canceling the subscription does not automatically delete the account data; rights over personal data can be exercised according to the Privacy Policy.
9. Withdrawal and refund
When the relationship is subject to consumer protection rules, the right of withdrawal may be exercised within seven days of the remote purchase, through the same electronic means made available for the purchase or through the support channel, without unjustified barriers. Nyv IQ will electronically confirm receipt and, once the right is recognized, will request a full refund from the payment provider and provide the reference number. The time for the credit to appear on the card depends on the issuer and the payment network. Nothing in these Terms reduces mandatory rights provided by law.
10. Support
The contact form sends a confirmation with a reference number to the email provided. Nyv IQ will respond to consumer requests within five days, without prejudice to faster handling of urgent incidents. The customer should describe the problem without sending passwords, keys, full card numbers or sensitive documents by email.
11. Account, credentials and acceptable use
The customer must keep their information correct, protect their credentials and report any suspected unauthorized access. It is prohibited to exploit vulnerabilities, bypass plan limits, interfere with the service, access third-party accounts, register content without authorization or use Sentinel for unlawful purposes. Proportionate blocking measures may be applied to protect customers, sources and infrastructure, preserving applicable legal rights.
12. External sources, availability and limits
Sentinel depends on pages, APIs, networks, messaging providers and other external services that Nyv IQ does not control. Layout changes, blocks, outages, incomplete data, request limits or delivery delays may reduce or interrupt a collection or an alert. Nyv IQ applies retries, observability and operational controls, but does not guarantee uninterrupted operation, capture of every change, instant delivery, sales, margin, stock or financial results.
13. Intellectual property and customer data
The brand, software, interface and documentation belong to Nyv IQ or its licensors. The subscription grants a limited, revocable and non-transferable right of use while it is in effect. The customer remains responsible for the data and addresses they provide and declares that they are authorized to use them in the purchased monitoring.
14. Privacy and records
The processing of personal data follows the Privacy Policy. Security, acceptance and billing events and relevant changes may be recorded to perform the contract, prevent fraud, comply with obligations and defend rights, observing necessity, restricted access and retention by criteria.
15. Nyv Recupera
Nyv Recupera remains in rollout and assisted partnership, subject to its own proposal, scope, responsibilities, data processing rules and contract. It is not part of the plans above and cannot be purchased through the Sentinel checkout. Sending an expression of interest does not create a contract or authorize any charge.
16. Changes and governing law
Material changes will be identified by a new version and date. If they affect an ongoing relationship, they will be communicated through the available channel and applied in accordance with the contract and the law. These Terms are governed by Brazilian law. Where there is a consumer relationship, the courts of the consumer's domicile are preserved; in other cases, the legal rules on jurisdiction apply.
