Privacy Policy

Interviewium is a coding-interview practice app for iOS with a companion website. This policy explains what we collect, why, and the choices you have. We keep data collection to what the product needs to work — nothing is sold.

Information we collect

• Account.When you sign in with Apple or Google, we receive your email address and, if provided, your name. Apple's Hide My Email is supported.
• Practice content and progress. The problems you attempt, the code and solution steps you write, submission scores, feedback, and streaks. This lets your work sync between the app and the website.
• Purchases. Subscriptions are processed by Apple. We receive the transaction identifiers Apple provides to confirm your entitlement. We never see your card or payment details.
• Usage and device data. Product-analytics events (screens viewed, features used) and a device identifier used to enforce free-trial limits before you sign in.

How we use your information

• Run and save your practice sessions across devices.
• Grade your solutions. Code you submit for review is sent to our AI model provider to produce a score and written feedback.
• Manage subscriptions, trials, and access to paid content.
• Understand which features help and fix what doesn't, using aggregate analytics.

Service providers we share data with

We share the minimum necessary with vendors that operate the service on our behalf:

• Supabase — authentication and database hosting for your account and progress.
• Apple — Sign in with Apple and subscription billing.
• Google — Sign in with Google.
• Our AI model provider — grades submitted code and returns feedback.
• Amplitude — product analytics.

We do not sell your personal information or share it for advertising.

Data retention and deletion

We keep your account and practice data while your account is active. You can delete your attempts from within the app, and you can request full deletion of your account and associated data by emailing us at teymurgg321@gmail.com. We will delete it within 30 days, except where we must retain records for legal or billing reasons.

Security

Data is encrypted in transit. Access to production data is restricted to what is needed to operate the service. No system is perfectly secure, but we work to protect your data.

Children's privacy

We may update this policy as the product evolves. Material changes will be reflected by a new effective date at the top of this page.
