Your practice, your choice.
Written practice
By default, written exercises hold answers and attempt history in browser memory. Reloading or closing clears them. In the IB practice room, you can opt into “Save on this device” to keep drafts, explanations, attempts, text highlights, flashcard self-ratings and the last scenario in this browser’s local storage. Avoid this setting on shared devices. Turning it off removes the saved copy while keeping the current tab available; “Clear saved practice” also clears the current tab. Browser storage can be removed by your browser and is not a backup. No analytics tracker, account, email submission or automatic answer upload is included. If you choose to download your work, a JSON file is saved to your device.
Voice preview
Starting a voice interview requires explicit audio consent and browser microphone permission. OpenAI processes audio to generate speech, transcripts and feedback. This application does not record raw audio or save transcripts on the server. Provider processing and retention terms apply separately. A transcript in browser memory can be exported by you.
Other services
Following a Cal.com or other external link opens that service, which has its own privacy terms. Hosting providers can process normal request information; this version has only been run locally.
Research participation
Candidate interviews, recording, transcript sharing or publication of feedback require a separate clear invitation and appropriate consent. No candidate outcomes are inferred from a practice score.
