2. How We Use Your Information
- Provide the Service: Process your audio, generate scores and feedback, maintain your progress and streaks.
- Personalization: Deliver focused drills based on your weaknesses, adapt difficulty levels, recommend relevant practice.
- Shareable Links: Enable you to generate links to share specific responses with coaches, tutors, or peers.

- Security & Compliance: Prevent fraud and abuse, enforce our Terms of Service, comply with legal obligations.
3. Audio Processing & Retention
We process your audio recordings to generate transcripts, pronunciation scores, fluency metrics, and content analysis. Where technically feasible, we extract non-reversible acoustic features for scoring purposes and minimize retention of raw audio files.
Retention: Audio recordings are typically retained for 30-90 days to allow you to review your practice history. After this period, we may delete the audio while retaining scores and transcripts. You can delete recordings at any time from the app. Access to audio is restricted to authorized personnel and automated systems for scoring purposes only.
4. Shareable Links
When you create a shareable link, anyone with the link can view the associated content (audio, transcript, scores). Shared items remain accessible until you delete them or disable sharing. You control what you share and with whom. We are not responsible for how recipients use shared content.
5. Data Sharing & Third-Party Services
We do not sell or rent your personal data. We may share information with third-party service providers who help us operate the Service:

- AI Processing: OpenAI, Google Cloud (speech-to-text, AI scoring)
- Analytics: PostHog (product analytics, feature usage)
