Your data, plainly explained.

Interview Expert is operated by Great X Inc (Taiwan). We're the data controller for the information described below. Reach us at support@interviewexpert.ai.

• No name, email, or phone number is required to use the app.
• No tracking across other apps or websites. (See our App Store privacy declaration for the formal version.)
• No advertising identifiers (IDFA) accessed.
• No location data.
• No contacts, photos, calendar, or microphone access beyond what you explicitly grant for recording answers.

We do not use any analytics, marketing, advertising, or session-replay third parties.

• Supabase (database, edge functions, file storage): our backend infrastructure provider. Data is stored in their AP-Northeast-1 (Tokyo) region.
• Google Gemini API, our AI coaching model. Your transcripts are sent to Gemini for evaluation. Per Google's API terms, this data is not used to train Google's models.
• Apple App Store / IAP handles all payment processing. We never see your payment details.

What we collect: to generate AI feedback we collect the interview and practice answers you submit (spoken answers as on-device transcripts — the audio itself never leaves your iPhone), any target role, company, or resume context you choose to provide, and basic usage data (attempt scores, practice metadata, and standard technical logs).

How we collect it: answers you type are captured directly in the app; spoken answers are recorded on your device and transcribed (see “What we collect, and why”). The transcript, metrics, and any context are sent to our backend over an encrypted connection.

How it is used: we use this data solely to power the app — generating AI feedback and scores, follow-up and practice questions, interviewer voice output, and your saved history and mastery tracking. We do not sell it, share it with advertisers, or use it for cross-app tracking.

Sharing with Google Gemini (Google LLC): to produce this feedback, the text transcripts of your answers — never your audio, which stays on your device — are sent to the Google Gemini API, operated by Google LLC, which acts as our service provider. The details you enter, such as your target role and company, are also sent to Google Gemini to generate interview questions relevant to that company. Google processes this data only to return results to us and, per Google's API terms, does not use it to train Google's models. Google maintains security and privacy safeguards that provide a level of data protection equivalent to the protections described in this policy.

Your consent and control: the iOS app asks for your explicit consent before any of your data is sent to Google Gemini for the first time, and AI features stay off until you agree. You can withdraw consent at any time in the app under Settings → AI features; once withdrawn, no further data is sent to Google and AI features are unavailable until you opt in again.

• Delete your data anytime. Settings → Delete all my data wipes everything on your iPhone; emailing us at support@interviewexpert.ai with your device ID (included in your data export) removes it from our backend.
• Export your data anytime. Settings → Export my data gives you your transcripts and attempts as JSON, right on your phone.
• Stop using the app. Uninstalling removes all local data. Backend data can be deleted anytime on request (see Your rights above).

Interview Expert is intended for users 17 and older preparing for professional job interviews. We do not knowingly collect data from children under 13. If you believe we have, please contact us and we'll delete it immediately.

If we change anything material (what we collect, who we share with, how long we keep it), we'll update the "Last updated" date above and, for significant changes, surface a notice in the app.
