SvanaAiRefunds and cancellations
Cancelling
You can cancel a plan at any time (Manage plan on your account page, or in Google Play for purchases made there). It stays active until the end of the period you paid for.
Refunds
[EDIT: your refund rules, e.g. a full refund within 7 days of the first payment, none for renewals]
To ask for a refund, write to support@svanaai.com from your account's email address, with your receipt number.
Free trial
The free trial costs nothing and ends by itself; nothing is charged unless you choose a plan.
