The camera, explained
Real tasks use your camera to check the work is yours. Only event flags are kept, never video or images.
Common questions
- How long until I can apply?
- Finish 3 tasks on a real track. You can start up to 3 real tasks in any 24 hours, so the minimum is one day of steady work.
- Do I need a camera?
- Only for real tasks, to check the work is yours. Practice tasks need no camera, have no daily limit and are never shown to employers. No video or images are stored, only event flags.
- Can I use AI tools or search the web?
- The workspace has its own task assistant, and the clipboard works only inside the workspace. Integrity signals are shown to employers apart from your score and never change it.
- Who can see my record?
- Employers you apply to see an anonymous id and your results. Your name and contact details stay hidden until they shortlist you.
- Can I delete my data?
- Yes. Your record is kept while your account is active so you can reuse it, and it is deleted or anonymized when you delete your account. The privacy policy has the details.
- Does it cost anything?
- Candidates do not pay. Employers pay for the platform.
