Cancellation Brilliant: Easy Method
What is Brilliant
Brilliant is an online learning platform offering bite-sized, interactive lessons in mathematics, science, and computer science. It provides a Premium subscription that unlocks full access to course tracks, problem sets, and guided explanations across multiple subjects.
How to cancel Brilliant
- Web (direct purchase at brilliant.org): Log in at brilliant.org → go to Subscription Settings → click "Cancel Subscription". This stops future charges but keeps Premium access until the end of your billing period. If eligible, a "Cancel and Refund" option may appear to cancel and request a refund. See Brilliant help: cancel or change subscription.
- Apple App Store (iOS): On your device open Settings → tap your name → Subscriptions → select "Brilliant" → Cancel Subscription and confirm. Apple handles refunds; request refunds via Apple's Report a Problem page. See Brilliant's guidance at help.brilliant.org.
- Google Play Store (Android): Open the Play Store → tap your profile icon → Payments & subscriptions → Subscriptions → select "Brilliant" → Cancel Subscription and confirm. Request refunds through Google Play's order history or support. See Brilliant help for details.
What happens when you cancel
When you cancel a Brilliant subscription purchased directly on the web, future billing stops but your Premium access continues until the end of the current billing period. For store purchases (Apple or Google), cancellation prevents future renewals through that store but access typically remains until the period you already paid for ends. Your Brilliant account and progress remain; cancellation does not automatically delete your account or learning history unless you request account deletion separately.
Will I get a refund?
Brilliant's published policy is that refunds are not generally offered under their Terms of Use, though they may consider exceptions on a case-by-case basis. For web purchases, eligible accounts may see a self-serve "Request a Refund" option in Subscription Settings; otherwise support reviews requests manually. For subscriptions purchased through the Apple App Store or Google Play, refunds must be requested through Apple or Google respectively (for example, Apple's "Report a Problem" system or Google Play order history). See Brilliant refund policy and Brilliant help: how do I get a refund?.
Brilliant plans and pricing
| Plan | Price (CAD) | Period | Features |
|---|---|---|---|
| Monthly (in-app purchase on iOS) | C$28.99 | Monthly | Brilliant Premium - full access (exact features unspecified) |
| Annual (Canadian reported) | C$244.40 | Annual (approx. C$20/month by reported billing) | Brilliant Premium - full access (user-reported actual charge) |
Your consumer rights in Canada
Digital services that are delivered immediately (subscriptions providing immediate access to content) may be exempt from an automatic statutory 14‑day cooling‑off period in Canada, so Brilliant is not automatically bound by a national unconditional 14‑day refund right in every case. Provincial rules differ: under Quebec's Consumer Protection Act, there is not generally an unconditional 14‑day refund once a digital service has been fully delivered, though businesses must meet any notice and disclosure requirements for automatic renewals. If Brilliant did not clearly disclose renewal terms or failed to provide required renewal notices, provincial consumer protection laws may give you additional grounds to challenge a renewal or request redress.
If you cannot resolve the issue with Brilliant, Canadian consumers may consider a chargeback through their bank or credit card issuer; note that initiating a chargeback can limit Brilliant's ability to assist and may have time limits and requirements set by your payment provider.
Customer experiences
Public reviews show a mix of positive and negative experiences. Many users praise Brilliant's user-friendly design, engaging bite-sized lessons, clear explanations and helpful visuals, and several reviewers note quick or understanding customer support in billing or refund cases. At the same time, recurring negatives reported on public review sites include unauthorized or unexpected charges, subscription renewals after attempted cancellation, and difficulties obtaining refunds. Several complaints allege that cancellations did not process correctly and led to automatic renewals.
Documentation checklist
- Proof of purchase (receipt or order confirmation), account email, date(s) of charge, transaction ID and payment method; screenshots of subscription settings showing status; any confirmation emails from Brilliant or store receipts; correspondence with Brilliant support (dates and content); Apple/Google order IDs if purchased through a store; bank or card statement entries related to the charge.
Common mistakes
Some common pitfalls include cancelling from the wrong place (for example uninstalling the app but not cancelling the subscription through the App Store / Google Play or Brilliant web settings), assuming a cancellation went through without checking subscription status, or contacting the wrong support channel (Brilliant vs. Apple/Google) for a store purchase. Another frequent example is using multiple Apple IDs or Google accounts - the subscription may be tied to a different account than the one you think. Always confirm cancellation in the relevant account's subscription settings and keep screenshots or confirmation emails as evidence.

| Method | Refund | Difficulty |

After cancelling
After you cancel, check your subscription status in the place you cancelled (Brilliant account settings, Apple Subscriptions, or Google Play Subscriptions) and retain screenshots or confirmation emails. If you need help, start with Brilliant's help articles: how to cancel or change and how to get a refund. For store purchases, use Apple's Report a Problem (reportaproblem.apple.com) or Google Play's support via your Order History (Google Play refunds).
