Terms of Service

Last Updated: September 1, 2026 · Version 1.0

1. Introduction

Welcome to Sentiment Lens, operated by BuddyPig ("we", "us"). By accessing or using our service at sentimentlens.buddypig.com (the "Service"), you confirm that you are at least 18 years old and agree to these Terms and our Privacy Policy. If you do not agree, please do not use the Service.

2. Service Description

BuddyPig provides an AI-powered platform that lets users submit the text of a personal letter and receive a structured sentiment-analysis report (a "HeartRead Report"), including a dual-perspective reading, potential misread moments, and a shareable AuraCard. The Service is a digital product delivered over the internet; access is granted immediately upon payment confirmation. The Service uses third-party AI model providers and is not affiliated with or endorsed by them. AI-generated output may contain errors — please review it before relying on it.

3. Account

Some features require signing in via our authentication provider (auth.ReplyPin). You are responsible for keeping your credentials confidential and for all activity under your account. Contact support@buddypig.com immediately if you notice unauthorized use.

4. Credits & Billing

The Service runs on credits. You may purchase credit packs at any time (currently: 1 credit for ¥1.00, or a 3-credit pack for ¥2.50). One credit is consumed to generate one full HeartRead Report. Each top-up is a one-time transaction: completing a purchase authorizes BuddyPig to charge your payment method for the amount shown at checkout. Payment card data is processed exclusively by our PCI-DSS-compliant payment processor, Waffo Pancake, and is never stored on our servers. Prices exclude applicable taxes unless stated otherwise.

5. Credit Validity

Purchased credits are valid for 12 months from the purchase date, unless stated otherwise at checkout; we will remind you before they expire. If your account is terminated, unused credits remain available for 90 days, then expire without refund unless required by law.

6. Refunds & Billing Disputes

As a general rule, consumed credits are non-refundable. We do refund in these cases:

• Credits that remain entirely unused within 7 days of purchase.
• Duplicate charges caused by billing errors.
• Charges for a report that failed to generate due to an error on our side (refunded automatically to your credit balance).

Nothing in these Terms limits any mandatory rights you have under applicable law (such as statutory withdrawal rights for first-time purchasers, which end once the Service is used). For refunds or billing issues, email support@buddypig.com with your account email and transaction ID — please contact us before initiating a dispute with your bank. We respond within 2 business days and process eligible refunds within 5–10 business days.

7. AI Content & Intellectual Property

Subject to these Terms, the reports generated from your input belong to you and may be used for any lawful purpose. You grant us a limited license to process your submitted content solely to provide the Service; we do not use it to train AI models without your explicit consent. A HeartRead Report is a reading-perspective inference of your text — it cannot predict any reader’s real thoughts or reactions.

8. Acceptable Use

You may not use the Service to generate or attempt to generate:

• Illegal, defamatory, harassing, or fraudulent content.
• Deepfakes or AI-synthesized content impersonating real individuals.
• Sexually explicit content, or any content involving minors.
• Hateful, violent, or extremist content.
• Content that infringes intellectual-property, publicity, or privacy rights.
• Malware, phishing, or cyberattack material.

You also agree not to: use the Service's inputs, outputs, or derived data to train, fine-tune, benchmark, or distill any competing AI model; scrape or collect outputs at scale; present AI output as the work of a human professional where doing so could cause harm; circumvent security or usage limits; or resell access without written approval. You may not submit private correspondence of another person without a lawful basis to do so. We may block, remove, or restrict content or accounts that violate these Terms.

9. Privacy

Your use of the Service is governed by our Privacy Policy. The Service itself does not persistently store the letter text you submit.

10. Disclaimers & Limitation of Liability

The Service is provided "as is" without warranties of any kind. Sentiment Lens provides linguistic and sentiment insights for personal reference only — it does not constitute professional psychological, medical, legal, financial, or relationship advice. To the maximum extent permitted by law, BuddyPig shall not be liable for any indirect, incidental, consequential, or punitive damages; our total liability is limited to the amount you paid us in the 12 months preceding the claim.

11. Termination & Governing Law

We may suspend or terminate accounts that materially breach these Terms, engage in suspected fraud, or where required by law; if we terminate for reasons other than your breach, we refund the unused prepaid portion pro-rata. You may delete your account at any time via support@buddypig.com. These Terms are governed by the laws of the People's Republic of China. Before any formal proceedings, please contact us to attempt informal resolution.

12. Changes & Contact

We may update these Terms from time to time and will notify material changes at least 15 days in advance by email or an in-service notice; continued use constitutes acceptance. Questions about these Terms or billing: support@buddypig.com.
