The verified policy
The two verified policy points are straightforward: LangPanda can be canceled anytime, and the product offers a 30-day money-back guarantee. Those are the useful promises to assess before buying or leaving; they do not justify assuming unverified page labels, buttons, or support workflows.
Cancel from the account
Use the account area to cancel the subscription, then confirm the next billing cycle is no longer scheduled. If the current interface is unclear, use LangPanda's own account or support material for the up-to-date click path. This avoids publishing instructions that can go stale as soon as the account UI changes.
What the refund window means
LangPanda offers a 7-day free trial and a 30-day money-back guarantee. Together, that is the practical risk window: test the workflow during the trial, then use the stated guarantee if the paid product does not fit. Keep records of the request and check the current policy terms when acting.
Before you leave
If price is the problem, LangPanda's annual plan is approximately $4.91 per month. If the issue is platform coverage or study workflow, compare alternatives on the scoreboard. Trancy is the free subtitle-tool route, but its free tier has no Anki export and only basic flashcards rather than a full SRS. Language Reactor also has a substantial free tier.
A cancellation can be the right answer. The useful comparison is between the feature actually missing and the alternative that supplies it, not between marketing labels.
