Do I need to give Zvelt my Google password?
No. Sign in only on Google pages and Google Play. Zvelt will never ask for your Google password.
Must I use the app every day?
No daily schedule is required. Please complete the four missions and remain opted in continuously for at least 14 days.
Can I leave the test?
Yes. You can opt out at any time. If you leave before day 14, your account will not count toward the continuous testing requirement.
Will my feedback become a public review?
