Amlin Pro is $10/month, or $108/year (save 10%).

Click Upgrade to Pro: it appears in Settings → Account & Sync, and on the notice that appears when you hit a limit. Secure checkout opens in your browser, handled by Stripe; Amlin never sees or stores your card details.

Once payment completes, your plan updates automatically. If the app still shows Free, close and reopen Settings.

The Upgrade button appears only when you're signed in: your plan is attached to your account, so it follows you to every device you sign in on.

You can also buy Pro on amlin.ai before you've ever opened the app. After checkout you land on the download page with two activation steps. Install Amlin, then sign in with Google using the same email you used at checkout. The sign-in screen in the app carries the same reminder, and shows Pro plan active the moment your plan attaches.

If the app still shows Free, you most likely signed in with a different Google account than your checkout email. Sign out and back in with the matching one, or contact us and we'll sort it out.

Pro subscribers have a Manage billing button in Settings → Account & Sync. It opens Stripe's secure customer portal, where you can update your card, download invoices, or cancel on your own. If anything looks off, email [email protected] and we'll sort it out, usually the same day.

You keep Pro through the end of the period you've already paid for, then move to the Free plan. Nothing is deleted:

You can upgrade again at any time, and your history is waiting where you left it.
