Terms of Use

Last updated: August 15, 2026 · Effective: August 15, 2026

These Terms of Use (“Terms”) are a binding agreement between you and BARETTA ASSESSORIA COMERCIAL LTDA, CNPJ 08.763.857/0001-75 (“Nudge Buddy”, “we”, “us”), governing your use of the Nudge Buddy website and application (the “Service”). By creating an account or using the Service, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.

1. What Nudge Buddy is

Nudge Buddy is a writing coach. You paste your own writing and we return a score, questions that probe the weak spots, and flags for phrasing that may read as machine-generated. We never write, rewrite, or produce replacement text for you — the Service only asks and points; the words stay yours. Its output is advisory and meant to help you improve your own work.

2. Eligibility and age

You must be at least 13 years old to use the Service. If you are under 18, you may use the Service only with the consent and supervision of a parent or legal guardian, who agrees to these Terms on your behalf and is responsible for your use. By using the Service you represent that you meet these requirements and that the information you provide is accurate.

3. Your account

You are responsible for the activity under your account and for keeping your login credentials secure. Use a strong, unique password and notify us at support@nudgebuddy.app if you suspect unauthorized access. Accounts are for a single person; do not share credentials. We may refuse, suspend, or terminate accounts that violate these Terms.

4. Acceptable use

You agree not to:

  • use the Service for anything unlawful, or to submit content that is illegal, infringing, or that you have no right to submit;
  • attempt to make the Service write, rewrite, complete, translate, or generate text on your behalf, or otherwise use it to defeat its question-only purpose;
  • attempt to bypass usage limits, rate limits, or security measures; access the Service through automated means (scraping, bots) beyond normal use; or overload or disrupt it;
  • reverse engineer, extract, or attempt to derive the underlying models, prompts, or source code, or use the Service to build a competing product or to train another model;
  • upload malware, or attempt to gain unauthorized access to our systems or other users' data;
  • submit another person's confidential or personal data without a lawful basis.

Academic and professional integrity. Nudge Buddy is a coaching aid, not a way to have your work produced for you (and it does not produce it). You are solely responsible for complying with your school's, employer's, or publisher's rules on the use of writing assistance and AI tools, and for the integrity of the work you ultimately submit.

5. Your content

You keep all rights to the text and materials you submit (“Your Content”). You grant us a limited, worldwide, non-exclusive license to store, process, and transmit Your Content solely to operate and provide the Service to you — including sending it to our AI provider to generate the analysis, as described in the Privacy Policy. This license ends when you delete the content or your account, except for backups or logs that expire on their normal schedule and copies we must keep by law.

You are responsible for Your Content and represent that you have the right to submit it. Please do not paste highly sensitive information. We do not use Your Content to train AI models or for advertising.

6. AI output — no warranty of accuracy

The scores, questions, and flags are generated by AI and are advisory only. They may be incomplete, inaccurate, or not suited to your purpose, and they are not professional, legal, academic, financial, or other expert advice. In particular, the Human Voice check is a self-help signal about how writing reads — it is not proof that any text was or was not written by AI, and must not be used to accuse or penalize anyone. You are responsible for evaluating and deciding what to do with the output and for your final work.

7. Pro plan, prices, and payment

The Service offers a Free plan with a daily limit and a paid Pro plan.

Prices. Pro is sold per period as a one-off purchase with no auto-renewal: R$ 29.90 per month or R$ 239.00 per year. Amounts are shown in Brazilian Reais (BRL) and presented to you on the payment screen before you confirm. We may change prices for future purchases; the price that applies is the one shown at the time of your purchase.

How it works. When an approved payment completes, your Pro access runs for the purchased period (30 or 365 calendar days) and expires at the end of that period, with no automatic charge and no automatic renewal. To continue on Pro after it ends, you make a new purchase. We do not store your payment details or make recurring charges.

Payment processor. Payments are processed by Mercado Pago, which accepts Pix, boleto, and card. Your payment data is also governed by Mercado Pago's terms and privacy policy. We do not have access to your full payment-method details.

Invoice. We issue an electronic service invoice (NFS-e) for each approved payment, under the CNPJ of BARETTA ASSESSORIA COMERCIAL LTDA.

Right of withdrawal (Brazilian Consumer Code, art. 49). Because this is a purchase made over the internet (away from business premises), you may withdraw from a Pro purchase within 7 (seven) calendar days of the payment date, without giving a reason. To do so, write to support@nudgebuddy.app from your account email. Within that period we refund the amount paid in full, to the same payment method where possible, and end Pro access when the refund is processed.

Complimentary access. We may grant complimentary Pro access to certain accounts at no charge. Such a grant is not a paid plan and may be ended at any time.

8. Intellectual property

The Service — including its software, design, text, logos, and the “Nudge Buddy” name — is owned by us or our licensors and protected by law. We grant you a limited, personal, non-transferable, revocable license to use the Service under these Terms. You get no rights in our IP beyond that license. Your Content remains yours (Section 5).

9. Third-party services

The Service relies on third parties (including Supabase, Anthropic, Upstash, Vercel, PostHog, and Cloudflare) to function. Their processing of personal data is described in the Privacy Policy. We are not responsible for third-party services outside our control, and their own terms may apply.

10. Availability, “as is”, and changes to the Service

We work to keep the Service available but do not guarantee it will be uninterrupted, error-free, or permanently available. The Service is provided “as is” and “as available”, without warranties of any kind except those that cannot be excluded by law. We may modify, suspend, or discontinue features at any time.

11. Limitation of liability

To the maximum extent permitted by law, we are not liable for indirect, incidental, special, or consequential damages, or for lost profits, data, or goodwill, arising from your use of the Service. Our total aggregate liability for any claim relating to the Service is limited to the greater of the amount you paid us in the 12 months before the claim or R$ 100.

Nothing in these Terms limits or excludes any right or remedy you have under mandatory law, including the Brazilian Consumer Protection Code (Código de Defesa do Consumidor). If you are a consumer, the protections that law gives you prevail over any conflicting term here.

12. Indemnification

You agree to indemnify and hold us harmless from claims, losses, and expenses arising out of Your Content or your breach of these Terms or of applicable law, except to the extent caused by us.

13. Suspension and termination

You may stop using the Service and delete your account at any time. We may suspend or terminate your access if you materially breach these Terms, misuse the Service, or where required by law. On termination, the licenses you granted end and your content is deleted as described in the Privacy Policy, except data we must retain by law. Sections that by their nature should survive (e.g., 5–6, 8, 11–12, 14) survive termination.

14. Changes to these Terms

We may update these Terms. If we make material changes, we will notify you (by email or an in-app notice) before they take effect. Your continued use after the effective date means you accept the updated Terms, to the extent permitted by law. If you do not agree, stop using the Service and you may delete your account.

15. Governing law and forum

These Terms are governed by the laws of the Federative Republic of Brazil. The courts of the Comarca de São Paulo, State of São Paulo, Brazil have jurisdiction over disputes — except that, if you are a consumer, you may also bring a claim in the courts of your own domicile, as guaranteed by the Código de Defesa do Consumidor.
