Billing and trial
How the 14-day free trial works, adding a payment method, finding your invoices, changing plan or going annual, and how to cancel or delete your account.
Everything lives in Settings → Billing, split into Overview and Payment.
The free trial
Your trial starts automatically when you create your account: 14 days, full access, no credit card.
Nothing is charged during the trial, and nothing is charged when it ends — the sync simply pauses until you subscribe.
Adding a payment method
During the trial, Add payment method on Settings → Billing. After it, Manage billing is where you update your card. Payments are handled by Stripe; card details never touch our servers.
Your invoices
Settings → Billing → Payment lists every invoice. Manage billing opens the Stripe customer portal, where you can download them, update your card, or change your billing address and VAT number.
Changing your plan
Under Choose your plan, on Settings → Billing → Overview:
| Button | What happens |
|---|---|
| Choose | During the trial: sets the plan you pay for when it ends. Nothing is charged. |
| Move up | At once. You pay the difference for the rest of the current period. |
| Switch at renewal | At your next renewal. Nothing is refunded. |
| Keep | Cancels a switch you had scheduled. |
When a month goes over your plan's cap, we ask you to move up — Plans and pricing explains the 14 days and the pause.
Switching to annual
Pick Monthly or Annual above the plans before you choose one, during the trial or when you subscribe. Annual costs ten months for twelve. Once you pay, the billing period stays as it is — contact us to switch it.
Cancelling
Settings → Billing → Manage billing, then cancel in the page that opens. You keep access until the end of the period you have already paid for. Nothing is deleted when it lapses — your data is still there if you come back.
Deleting your account
That is a different action, on Settings → Account. It is permanent: your data is erased and the link to your KDP account is released.
