Write to support@vratka.app or use Settings → Send feedback in the app. A human reads every message.
Forward the order confirmation to your personal Vratka address (Settings → Forwarding address), scan the receipt, share a screenshot or PDF to Vratka, paste the e-mail text, or type it in. Vratka reads the shop, items, prices and dates, and shows anything it's unsure about for you to check.
Yes. In Gmail on the web: Settings → Forwarding and POP/IMAP → Add a forwarding address → your Vratka address. Gmail sends a confirmation e-mail to Vratka; the app shows you the code to confirm it. Then create a filter (for example from:(order OR objednavka OR shipped)) that forwards only purchase e-mails. The app's “Forward e-mails” screen has a ready-made filter to copy.
Tap any date and choose Why this date?. You'll see the rule (law or shop policy), the starting event and any assumptions. If the shop's rules have changed, use Something wrong? on the shop's page; we check every report.
An e-mail saying a refund was sent isn't the money in your account. Vratka marks it as sent and asks you to confirm when you see it; if less arrives than expected (for example the delivery charge was kept), it tells you how much is missing and helps you write to the shop.
