Contact us
For help with any Quantdesk product — Kandle, Prep10, or this site — email [email protected]. We usually respond within two business days.
What to include
- The product you need help with (e.g. Kandle, Prep10).
- Your device and OS version (e.g. Pixel 8, Android 15).
- The app version, if you know it (shown in the app settings).
- What happened, what you expected, and steps to reproduce it — a screenshot or screen recording helps a lot.
