Common questions
How do I restore my Pro purchase?
Open KalviApp, go to More → Go Pro, then tap Restore purchases. Use the same Apple ID or Google account you bought it with.
How do I cancel my subscription?
Subscriptions are billed by Apple or Google. On iPhone, open Settings → your name → Subscriptions. On Android, open Google Play → Profile → Payments & subscriptions → Subscriptions.
How do I get a refund?
Apple and Google handle all payments, so refunds are requested from them: reportaproblem.apple.com for iPhone, or Google Play for Android.
My test result did not upload.
Your answers are saved on the phone. Connect to the internet and open the app; the result uploads by itself.
How do I delete my account?
In KalviApp, go to More, tap your account at the top, then tap Delete account. Deleting your account does not cancel a subscription; cancel that with Apple or Google.
