Support
Sangat is made by one person, who answers the mail — usually within a day or two. [email protected], for everything.
Bought Pro, but it is not showing?
Pro lives on your account, not on a device. Open Settings and sign in with the email you bought with, and it follows. Bought inside a phone app? Sign in there first, or tap "Restore purchases" on its Sangat Pro page.
Still missing? Email with the address you paid with.
Reporting a bug
Say which device and browser you were on and what you expected to happen — a screenshot helps. For sound problems, say whether the tab or app was in the background.
Everything else
Refunds: seven days, no questions. Privacy and terms are short. For anything else — email.
