Privacy Policy

Effective date: October 3, 2026

1. Introduction

Welcome to SceneLingo ("we," "our," or "us"). SceneLingo is a language learning platform available on web and mobile. We are committed to protecting your privacy and being transparent about how we collect, use, and share your personal data.

This Privacy Policy explains what information we collect, how we use it, who we share it with, and your rights regarding your data. By using SceneLingo, you agree to the practices described in this policy.

The controller responsible for processing your personal data under the General Data Protection Regulation (GDPR) is Hefmen UG (haftungsbeschränkt), Walter-Paetzmann-Str. 36 a, 82008 Unterhaching, Germany, represented by its managing director Mengzhen Liao. You can reach us at support@scenelingo.com. Further company details are in our Impressum.

2. Data We Collect

We collect the following types of data to provide and improve our services:

2.1 Account Information

  • Identity Data: Your name, username, or display name.
  • Contact Data: Your email address.
  • Authentication Data: If you choose social login, we receive basic profile information from your identity provider. We do not store your passwords.

2.2 Learning Data

  • User-Generated Content: Text and content you create or submit while using our learning features.
  • Learning Progress: Your study history, progress records, and performance data.

2.3 Voice & Audio Data

  • Voice Input: If you use voice features, your device's microphone captures audio for speech recognition. The audio is sent over an encrypted connection to third-party speech recognition services, processed in real time to produce a text transcription, and then discarded. We do not store raw audio recordings, and only the resulting text transcription is saved with your conversation.

2.4 Technical & Device Data

  • Device Information: Device type, operating system, browser type and version, and screen resolution.
  • Network Data: IP address, approximate location (derived from IP), and connection type.
  • Usage Data: Pages visited, features used, session duration, interaction patterns, and performance metrics.
  • Error Data: Crash reports, error logs, and diagnostic data to help us identify and fix issues.

2.5 Payment Data

  • Subscription Information: Your subscription plan, billing cycle, and payment status.
  • Payment Processing: All payment information (credit card numbers, billing addresses) is processed and stored exclusively by our PCI-compliant payment processors. We never have access to your full payment card details.

2.6 Optional ChatGPT Connection

You may connect ChatGPT to SceneLingo through OAuth authorization. When you ask ChatGPT to save learning material, selected vocabulary or corrected sentences and their provided meanings and translations, explanations, examples and notes are saved to private scenes you own. To help select a destination, SceneLingo shares your current learning and translation language pair and a limited list of private scene names and identifiers with ChatGPT. Save confirmations include the destination, saved or existing item counts, and selected item text and identifiers.

This connection does not obtain or store raw ChatGPT audio or full conversation transcripts. We store authorization records and limited retry records, including request identifiers, request hashes and save results, to operate the connection and prevent duplicate saves.

3. AI Data Processing

SceneLingo uses third-party AI services to provide its language learning features. When you interact with AI-powered features, your learning content (such as text you submit) may be sent to these providers for processing.

  • We work with trusted, industry-leading AI providers. Your data is processed solely to fulfill your requests and is not used to train their general AI models.
  • Each provider is bound by data processing agreements that require them to handle your data securely and in accordance with applicable privacy laws.
  • We do not send your account credentials, payment information, or device identifiers to AI providers.

4. Third-Party Services

In addition to AI providers, we use trusted third-party services to operate SceneLingo. These service providers fall into the following categories:

  • Payment Processing: We use a PCI-compliant payment processor to handle subscriptions and billing. Your payment details (e.g., credit card numbers) are processed and stored exclusively by the payment processor — we never have access to your full card details.
  • Cloud Hosting & Infrastructure: Our application is hosted on secure cloud infrastructure. Standard technical data (IP address, page views, performance metrics) may be collected for operational purposes.
  • Error Monitoring: We use error tracking services to detect and fix issues. These services may receive error logs, device information, and diagnostic data.
  • File Storage: User-uploaded content is stored on secure cloud storage services.
  • Authentication: If you use social login, your identity provider shares basic profile information (such as email and name) with us to create and verify your account.

5. How We Use Your Data

We use your personal data for the following purposes:

  • Service Delivery: To provide and maintain the SceneLingo platform and its features.
  • Personalization: To tailor your learning experience based on your preferences and progress.
  • Account Management: To manage your account, process subscriptions, and communicate about your account status.
  • Improvement: To analyze usage patterns and improve our services, fix bugs, and develop new features.
  • Legal Compliance: To comply with applicable laws, regulations, and legal processes.

6. Data Retention

We retain your data for as long as your account is active or as needed to provide our services. Specific retention periods:

  • Account & Learning Data: Retained until you delete your account.
  • Voice Data: Raw audio is never stored on our servers.
  • Payment Records: Retained for up to 7 years as required by tax and financial regulations.
  • Error Logs: Automatically purged after 90 days.

When you delete your account, we permanently remove your personal data within 30 days, except where retention is required by law.

7. Data Security

We implement industry-standard security measures to protect your data, including: encryption in transit (TLS/HTTPS) for all data transmission, encrypted storage for sensitive data, secure authentication mechanisms, and regular security audits and vulnerability assessments. While we strive to protect your personal data, no method of transmission or storage is 100% secure. We cannot guarantee absolute security.

8. Your Rights

Depending on your jurisdiction (including GDPR, CCPA, and other applicable laws), you have the following rights:

  • Access: Request a copy of the personal data we hold about you.
  • Correction: Request correction of inaccurate or incomplete data.
  • Deletion: Request deletion of your account and associated data. You can do this directly in the app under Profile > Account > Delete Account.

9. Children's Privacy

SceneLingo is not directed at children under 13 (or 16 in the EEA). We do not knowingly collect personal data from children. If we learn that we have collected data from a child, we will delete it promptly. If you believe a child has provided us with their data, please contact us at support@scenelingo.com.

10. International Data Transfers

Your data may be transferred to and processed in countries outside your country of residence, including the United States, where our AI providers and infrastructure services are located. We ensure that appropriate safeguards are in place, including standard contractual clauses and data processing agreements, to protect your data in accordance with applicable privacy laws.

11. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any material changes by posting the updated policy on this page and updating the "Effective date" above. Your continued use of SceneLingo after any changes constitutes your acceptance of the updated policy.
