The short answer
Perfect Dictation is made by DeveloperData.net in Bangkok, so charges appear on your statement as DEVELOPERDATA.NET.
On your statement
Every Perfect Dictation payment shows as DEVELOPERDATA.NET. DeveloperData.net is the company that makes Perfect Dictation and several other products, and payments are taken by Stripe on its behalf.
Don't recognise a charge?
The charge lookup finds a payment by your email or your card's last four digits and tells you which product and plan it was for. You can ask about it there too, and a person replies.
Receipts
Every payment is listed under Payments on the Plan and billing tab of your account page, with a link to its receipt.
Prices and currency
Prices are in US dollars. If your card is in another currency, your bank converts it and may add a small foreign transaction fee.
