Does the AI AutoPost licence expire or need renewing?

No. The licence itself is free and does not expire: the plugin shows Expires: Never (lifetime) and your Dashboard shows Never (credits don't expire). There is nothing to renew to keep the plugin working.

• What you pay for is credits for AI rewriting, 1 credit per post rewritten with AI. Posts without AI use no credits. See pricing.
• The plugin re-checks the licence with algopointai.com regularly. If the server cannot be reached, it keeps working for up to 3 days.
• The licence stops working on a site only if you reset its domain, pause the key, or the key is switched off. Then the notice No active licence. Campaign execution is disabled. appears.

You can pause the key yourself with Pause key in your Dashboard and switch it on again with Turn key on. Your credits, campaigns and domain stay as they are.
