How to cancel Brilliant by mail
Collect the details you need
Start with the email on the account, the name of the plan or course bundle and the date of your last payment, so the request to Brilliant names the right account the first time.
Set out the request
The letter asks Brilliant to end the account, stop every future charge and confirm it in writing. Postbye fills it in from our English template.
Find the postal address
Check the contact or terms pages on brilliant.org for the current postal address, then mail the letter there by certified mail and keep the tracking number.
File the delivery record
It shows the date Brilliant received your letter. Check your next statement: no Brilliant charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Cancelling a learning subscription
Learning platforms push annual plans and free trials that turn into paid ones, so the request should name the plan and the date the trial or term ends.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
Brilliant lets you cancel directly (online (Subscription Settings > Manage subscription) or app store). A letter is the fallback that leaves a dated record when the direct route fails.
