If your subscription was canceled or lapsed, you can start it again from Settings → Account — your account and its data are waiting for you.
Steps
Sign in and go to Settings → Account.
Choose a plan and complete checkout through Stripe.
Once payment is confirmed, your account is active again.
What to expect
Your contacts, call history, properties, and settings are all still there — re-subscribing reconnects you to the same account, it doesn't start you over.
Right after checkout there can be a short delay while the payment confirmation syncs. If your account still shows as inactive for a moment, refresh the page.
Only the account owner can re-subscribe.
If you canceled but you're still inside your paid period, you don't need to re-subscribe yet — you already have access until the end date shown on Settings → Account.
