Cancel an iPhone or iPad membership
Apple owns that subscription. Open Settings → your name → Subscriptions → Koda and cancel there. Cancelling inside Koda cannot stop an Apple charge.
Cancel an Android membership
Google Play owns that subscription. Open Play Store → profile → Payments and subscriptions → Subscriptions → Koda and cancel there.
A purchase isn’t showing up
On mobile, open the membership screen and tap Restore purchases while signed in to the same Koda account you bought with. On the web, refresh once — provider confirmations can take a few minutes.
Change tier or switch to annual
Choose the new membership on the plans screen. Web changes are prorated by Polar; store memberships change through Apple or Google and take effect when the provider confirms.
See plansAsk for a refund
Web purchases: email us within 14 days of a first purchase and we’ll refund it through Polar. App Store and Play purchases are refunded by Apple and Google under their own policies — we can’t refund a store charge for you, but we’ll help you file it.
Read the refund policyHow the free trial works
Every tier and cadence opens with 7 free days for an eligible first-time member. Checkout shows the exact end date and first charge. Cancel before that date and nothing is charged.
Reset your password
Ask for a reset link from the login screen. If the email doesn’t arrive, check spam and confirm you used the address you signed up with.
Reset passwordDelete your account and data
Deletion removes your profile, progress, and learning history permanently. Cancel any active membership first — deleting an account does not stop a store subscription.
