Terms of Service
Welcome to YappZilla, operated by Konstantin Pavlovskii, an individual entrepreneur residing in Spain. These Terms of Service ("Terms") govern your use of the YappZilla mobile application and website at yappzilla.com (the "Service"). By creating an account or using the Service, you agree to these Terms. If you do not agree, do not use the Service.
1. Description of the Service
YappZilla is an AI-powered language practice application that provides conversation practice with intelligent tutoring agents. The Service includes grammar correction, vocabulary assistance, text-to-speech pronunciation, and a token-based usage system. The Service is intended for educational and entertainment purposes.
2. Eligibility and Accounts
- You must be at least 13 years old (or the minimum age required in your jurisdiction) to create an account.
- You may register using either an email address and password, or Sign in with Apple. If you use Sign in with Apple, your authentication is managed by Apple, and these Terms apply to your use of the Service once authenticated.
- You agree to provide accurate information when registering and to keep your password confidential (if you use email/password sign-in).
- You are responsible for all activity that occurs under your account.
- You can delete your account at any time from within the app. Upon deletion, your data is removed as described in our Privacy Policy.
3. Talk Tokens and In-App Purchases
3.1 Token system
- New users receive 100 free Talk Tokens upon registration.
- Tokens are consumed automatically as you use AI conversation and text-to-speech features.
- Additional tokens may be purchased as a Starter Package of 100 Talk Tokens for $9.99 USD via in-app purchase through the Apple App Store (and Google Play where available).
- Tokens do not expire. Once purchased, they remain available until consumed.
- Tokens are virtual currency tied to your account and have no cash value. They cannot be transferred, exchanged, or redeemed for cash.
3.2 Refund policy
- All token purchases are processed by Apple App Store (or Google Play). Refund eligibility is governed by the respective store's refund policy.
- For Apple: see https://support.apple.com/en-us/HT204084 for refund requests.
- For Google Play: see https://support.google.com/googleplay/answer/2479637 for refund requests.
- We do not issue direct refunds for in-app purchases. All refund requests must be submitted through the platform where the purchase was made.
- If a purchase is refunded by the store, the corresponding tokens will be removed from your account. If your token balance becomes negative as a result, your access to token-consuming features may be restricted until the balance is restored.
3.3 Apple and Google terms
In-app purchases are also subject to Apple's Media Services Terms and Conditions (https://www.apple.com/legal/internet-services/itunes/dev/stdeula/) and, where applicable, Google Play's Terms of Service. Those terms govern the purchase transaction itself, while these Terms govern use of the purchased tokens within the Service.
4. Acceptable Use
You agree not to:
- Use the Service for any unlawful, harmful, or fraudulent purpose.
- Attempt to reverse engineer, decompile, or extract the AI models, prompts, or internal systems.
- Share your account credentials or resell access to the Service.
- Manipulate the token system, exploit bugs, or use automated tools to consume tokens.
- Submit content that is defamatory, discriminatory, harassing, or otherwise objectionable.
- Interfere with the Service's servers, infrastructure, or other users' access.
Violations may result in account suspension or termination and forfeiture of any remaining token balance, without refund.
5. AI-Generated Content Disclaimer
The Service generates responses using artificial intelligence (large language models). AI-generated content may be inaccurate, incomplete, or inappropriate despite our efforts to maintain quality. YappZilla is a language practice tool, not a source of professional advice. Do not rely on AI responses for medical, legal, financial, or safety-critical decisions. Always verify important information independently.
Grammar corrections and vocabulary suggestions are educational in nature and may not reflect all regional or contextual variations of a language.
6. User Content
- You retain ownership of the messages you submit during conversations.
- You grant us a limited license to process your messages through AI providers solely to generate responses and improve the Service.
- We do not claim ownership of your content and will not use it for purposes beyond operating and improving the Service.
- You are responsible for ensuring you have the right to submit any content you type into the Service.
7. Intellectual Property
The Service, including its design, software, conversation topics, branding, and AI agent configurations, is owned by YappZilla and protected by intellectual property laws. You may not copy, modify, or distribute any part of the Service without our written permission.
8. Disclaimers
The Service is provided "as is" and "as available" without warranties of any kind, whether express or implied. We do not guarantee that the Service will be uninterrupted, error-free, or that AI responses will be accurate. Your use of the Service is at your sole risk.
9. Limitation of Liability
To the maximum extent permitted by law, Konstantin Pavlovskii (operating YappZilla) shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, arising from your use of or inability to use the Service. Our total liability for any claim shall not exceed the amount you paid us for tokens in the 12 months preceding the claim.
PostHog and Sentry are independent controllers of any data they process on their own behalf (for example, their own billing and account records). YappZilla's liability is limited to data it processes as a controller. We are not responsible for the practices of these independent controllers.
10. Account Deletion
You may delete your account at any time from within the app's settings. Account deletion is permanent and will remove your conversations, messages, token balance, Apple ID link (if applicable), and personal information as described in our Privacy Policy. Token balances are non-refundable upon account deletion.
Account deletion also automatically triggers deletion of your analytics and crash-reporting data on PostHog and Sentry. This server-side deletion may take up to 30 days to complete on the sub-processors' side.
11. Product Analytics and Crash Reports
The mobile app may collect anonymized product analytics events (such as screen views and feature usage) and crash or performance reports when you opt in via the in-app consent screen. Analytics events are processed by PostHog in the European Union; crash reports are processed by Sentry in the European Union. No conversation content is shared with these providers.
Your consent is requested the first time you open the app and can be changed at any time in the app's Profile screen under "Privacy & data". Declining or revoking consent does not affect your ability to use the Service — analytics and crash reporting are not required for the core language practice features. Further details are described in our Privacy Policy.
You can also request deletion of your analytics and crash data without deleting your account by using Profile → Privacy & data → Delete my data. This erases your anonymized usage history and crash reports from PostHog and Sentry, and turns off future collection. Your account, conversations, and progress are not affected. Deletion may take up to 30 days to fully process.
Some aggregate, anonymized metrics (such as "10 conversations started today") may be retained even after individual data deletion, since they are no longer linked to an identifiable user.
12. Sub-processors
We use the following sub-processors to operate the Service. A detailed list with DPA links is available in our Privacy Policy:
- PostHog — product analytics (EU)
- Sentry — error monitoring (EU)
- RevenueCat — subscription management (US)
- Stripe — payment processing (EU)
- Apple — Sign in with Apple
We will notify you in-app at least 30 days before adding a new sub-processor that processes personal data. You may object to the new sub-processor by emailing privacy@yappzilla.com.
13. Modifications to These Terms
We may update these Terms periodically. We will notify you of material changes within the app or by email. Continued use of the Service after the effective date of updated Terms constitutes acceptance of the revised Terms.
14. Termination
We may suspend or terminate your access to the Service if you violate these Terms or if we believe your activity poses a risk to the Service or other users. You may stop using the Service and delete your account at any time.
15. Governing Law
These Terms are governed by the laws of Spain, without regard to conflict-of-law principles. Disputes will be resolved in the courts of Spain, unless otherwise required by mandatory local law (such as the consumer protection laws of your country of residence).
