How to cancel Hiya by mail
Start with your account details
You will need the account email, the plan or product name and the invoice or order number from your latest receipt. Use exactly the details Hiya holds, so the request can be matched to your account.
Draft the request
State plainly that you want the Hiya account cancelled, further charges stopped and a written confirmation sent to you. Postbye sets this out in a ready English template (“Subject: Subscription termination – Hiya”).
Send the letter by certified mail
Use certified mail for the 98104 Seattle address in the next section, so the post office records the delivery. Write down the tracking number.
Save the tracking record
Once the letter is delivered, the date on the receipt is the date Hiya was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.

Cancelling a software or app subscription
Software plans are billed per plan or per seat, often yearly, and the app store version is billed by the store rather than the developer, so the request has to name the plan and who bills it.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
