01Acceptance of Terms

These Terms of Service ("Terms") govern your use of the Petline app and related services (the "Service"), provided by LAYSON EDUARDO VIEIRA (Brazilian Tax ID 46.110.023/0001-50, "Petline", "we"). By creating an account, accessing or using the Service, you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the Service.

If you use the Service on behalf of another person or organization, you represent that you have authority to bind them to these Terms.

02What Petline is

Petline is a pet health organization app. With it you can:

  • Register pets (name, species, breed, date of birth, sex, photo);
  • Log weight, vaccines, scheduled medications, tagged photos and notes on a timeline;
  • Receive local reminders and notifications;
  • Use the AI triage ("I need help") for initial guidance from a photo and description;
  • Chat with the AI assistant to ask general questions about caring for your pets;
  • View the digital ID card (Pet ID) and the history in Vet Mode; exporting the ID card (PNG/PDF) and the PDF vet report are Premium features.

The Service evolves continuously: features may be added, changed or discontinued at any time.

03Eligibility and account

  • You must be at least 13 years old (or the minimum age required in your country, e.g., 16 in parts of the EU) to use the Service.
  • You are responsible for keeping your credentials confidential and for all activity under your account.
  • Information provided at sign-up must be true, current and complete.
  • Notify us immediately at [email protected] if you suspect unauthorized use of your account.

04Plans, subscriptions and payments

Petline offers a free plan and a paid plan, Petline Premium, with additional features. Premium subscriptions are purchased and processed by the App Store (Apple) or Google Play (Google); we never have access to your card details.

  • Free plan: includes 1 pet and 3 AI uses per 24 hours (photo analysis and chat combined).
  • Petline Premium: includes unlimited pets, AI use without the free-plan limit (subject to a technical fair-use cap) and export of the ID card and the vet report.
  • Free trial: when offered, the free trial gives access to Premium at no charge for the period shown on the subscription screen (for example, 7 days). A payment method registered with the store is required. If you do not cancel before the trial ends, the subscription for the chosen plan starts automatically and the store charges the amount shown on the screen; from then on auto-renewal applies. If you cancel during the trial, nothing is charged and Premium access remains until the end of the trial period. The trial is available only once: anyone who has already subscribed to Premium or used the trial is not entitled to another, and eligibility is checked by the store.
  • Reminder before the first charge: about 2 days before the trial ends we send a reminder as an app notification and by email. The reminder is an additional notice: it may not arrive (notifications turned off, email in the spam folder) and its absence neither postpones nor cancels the charge. The date of the first charge is shown on the subscription screen, in the trial confirmation and in your store account.
  • Auto-renewal: subscriptions renew automatically at the end of each period unless cancelled at least 24h in advance.
  • Billing: handled by the app store, according to the chosen plan (monthly or annual).
  • Cancellation: any time through the store (iOS: Settings → Subscriptions; Android: Google Play → Subscriptions). Premium access remains until the end of the paid period.
  • Pricing: may change; changes will be announced in advance and do not affect the period already paid for.
Refunds are governed by Apple's and Google's policies, and by Brazilian consumer law where applicable. Refund requests must be made directly to the respective store.

05AI triage — guidance, not veterinary advice

Petline's AI triage is a guidance tool and does NOT replace a consultation with a licensed veterinarian. Petline does not provide veterinary services, does not issue diagnoses, and does not establish a clinical relationship with you or your pet.

The "I need help" feature sends the photo and description you provide, together with the pet's profile data, for analysis by an AI model from a third-party provider (Google Gemini API or OpenAI API), which classifies urgency and generates a general recommendation. Regarding this feature:

  • Results are automated, advisory in nature, and may contain inaccuracies.
  • In an emergency, seek a veterinarian immediately — do not rely on the app.
  • Decisions about your pet's health are your sole responsibility and should be made with a qualified professional.
  • We do not warrant the accuracy, completeness or suitability of the guidance for any specific case.

06Acceptable use

When using the Service, you agree not to:

  • Violate applicable laws or third-party rights;
  • Upload unlawful, offensive, fraudulent content, or content you have no right to share;
  • Attempt to access, copy or improperly interfere with the systems, accounts or data of other users;
  • Reverse engineer, decompile or exploit the Service beyond the permitted personal use;
  • Overload the infrastructure, automate abusive access, or circumvent usage limits;
  • Resell, sublicense or commercially exploit the Service without authorization.

07Your content and data

You retain ownership of the content you add (photos, pet data, notes). You grant Petline a limited, worldwide, revocable license to host, store, process and display that content solely to operate and improve the Service for you.

You are responsible for the truthfulness and legality of the content you record. Processing of personal data follows our Privacy Policy, and you may delete records or your entire account at any time.

08Intellectual property

Petline, its brand, logo, design, text, code and other elements are protected by intellectual property rights and belong to the Provider or its licensors. We grant you a personal, limited, non-exclusive, non-transferable and revocable license to use the app under these Terms. Nothing here transfers any rights in such property to you.

09Privacy and data protection

How we process your personal data is described in detail in our Privacy Policy, which is an integral part of these Terms. By using the Service, you acknowledge having read it.

10Disclaimer of warranties

The Service is provided "as is" and "as available", without warranties of any kind, express or implied. We do not warrant that the Service will be uninterrupted, error-free, secure against every threat, or fit for a particular purpose. Features that rely on third parties (stores, cloud providers, AI models) are subject to those third parties' availability.

11Limitation of liability

To the maximum extent permitted by applicable law, Petline and the Provider shall not be liable for indirect, incidental, special or consequential damages, nor for loss of data, lost profits, or damages arising from decisions made based on AI guidance.

Nothing in these Terms excludes or limits liabilities that cannot be excluded by law, including consumer rights guaranteed by Brazilian consumer protection law (CDC).

12Suspension and termination

You may end your relationship with us at any time by deleting your account in Settings → Delete account. We may suspend or terminate your access, with or without notice, in case of breach of these Terms, misuse, or legal requirement.

After termination, data is handled per the Privacy Policy (the account is deactivated immediately and the data is permanently erased after a 30-day grace period, i.e. within 31 days of the request, except where retention is legally required).

13Changes to the Terms and Service

We may update these Terms to reflect legal, regulatory or operational changes. When the change is material, we will notify you in the app or by email with at least 15 days notice. Continued use after the effective date constitutes acceptance of the updated Terms.

14Governing law

These Terms are governed by the laws of the Federative Republic of Brazil. The courts of the consumer's domicile shall have jurisdiction over disputes, as ensured by Brazilian consumer protection law, without prejudice to other legally available avenues.
