Techcookies (techcookies.com) is an interview preparation platform for software engineers. We are the data controller for the personal data described in this policy. You can reach us at privacy@techcookies.com.
When you sign in with Google or GitHub we receive your name, email address, and profile picture from that provider. We use this to create and identify your account, personalise your experience, and send you transactional emails (e.g. onboarding, Pro access approval).
We store the answers, diagrams, scores, and time you spend on practice sessions so you can resume work and track your improvement over time. This data is held in Google Firestore under your account UID.
If you click Accept cookies in the banner at the bottom of the page, we load Google Analytics 4 (GA4). GA4 sets cookies and collects:
If you click Decline, no analytics cookies are set and GA4 is never loaded. You can change your choice at any time by clearing the “tc_cookie_consent” key from your browser’s local storage. Your consent is remembered for 6 months and then re-asked.
GA4 is operated by Google LLC. Google’s privacy policy: policies.google.com/privacy.
We use Sentry to capture unhandled errors and performance issues in the application. When an error occurs, Sentry may collect a stack trace, the URL where the error happened, and browser/device type. Sentry does not receive your name or email. Error data is retained for 90 days.
Sentry’s privacy policy: sentry.io/privacy.
Transactional emails (welcome, Pro access notifications) are sent via Resend. We pass your email address to Resend solely for delivery. We do not send marketing emails without explicit opt-in.
We share data with the following processors, each under their own privacy policy:
| Processor | Purpose | Data shared |
|---|---|---|
| Google Firebase | Authentication, database | Email, name, photo URL, usage data |
| Google Analytics 4 | Usage analytics (consent-gated) | Page views, events, account UID |
| Sentry | Error monitoring | Stack traces, URL, browser type |
| Resend | Transactional email | Email address |
| Netlify | Hosting and edge functions | IP address (standard server logs) |
| Anthropic / OpenAI | AI-powered answer evaluation | Your practice answer text |
If you are located in the European Economic Area or the United Kingdom, you have the following rights regarding your personal data:
To exercise any of these rights, email privacy@techcookies.com. We will respond within 30 days.
Data is stored in Google Firestore with role-based access controls. All data in transit is encrypted with TLS. Admin operations require server-side Firebase Admin SDK authentication. We do not store passwords — authentication is delegated to Google or GitHub OAuth.
Techcookies is intended for adults (18+). We do not knowingly collect data from children under 16.
We may update this policy from time to time. Material changes will be announced via email to registered users. The “Last updated” date at the top of this page always reflects the current version.
