3. How We Use Your Data
We use your data to:
- Provide the Service — process your writing submissions, generate AI feedback, track your skill progress, and deliver your personalised learning experience.
- Improve the product — analyse usage patterns, identify areas where users struggle, and improve drills, feedback quality, and user experience.
- Maintain security — detect abuse, prevent fraud, and protect the integrity of the Service.
- Communicate with you — respond to support requests and send important service updates. We will only send marketing communications if you opt in.
4. AI Processing
- Your writing submissions are sent to third-party AI providers for feedback generation (band score estimates, per-criterion analysis, suggestions for improvement).
- We currently use services from OpenAI, Google (Gemini), and Anthropic, and may use additional providers (including self-hosted fine-tuned models) in the future. The specific provider used may vary by feature and over time.
- Where available, we configure AI providers not to use your data for model training. For example, OpenAI’s API data usage policy states that API inputs and outputs are not used to train their models.
- AI outputs may be inaccurate or incomplete. See our Terms of Service (Section 8: AI Disclaimer) for details.
5. Payment Processing
- All payments are processed by Paddle.com Market Limited (“Paddle”) as our Merchant of Record.
- Paddle collects and processes your payment information directly. We never see or store your payment details.
