The short answer
No, credits do not expire. They have no expiry date: purchased credits stay on your balance for as long as you like, and you can spend them at any time — a day later or a year later.
This applies to all credits
None of the credits on your balance have an expiry date — neither those bought as part of a pack nor those a Creator receives by converting earnings. Everything on your account stays available.
Where you can see your balance
Your current credit balance is always visible in your account — with a top-up button next to it. There you can also see the history of credits added and spent.
What if you delete your account
Credits are tied to your account. If you delete your account, any unused credits disappear with it and are not refunded as money. So before deleting it makes sense to spend the remainder. For refunds of unused credits, see the article «Refunds».
Could credits with an expiry appear
Right now all credits are non-expiring. If promotions with temporary bonus credits appear in the future, such credits may have a separate expiry — we will state this right in the promotion terms.
