Your membership tier and member number are visible on the Billing page next to your plan details.
What the member number is
The member number is a sequential number assigned when your account was created. Lower numbers mean earlier accounts. It's primarily a badge of seniority — no functional difference between numbers.
What the tier means
Membership tier reflects your standing as a subscriber. It's tied to how long you've been a paying member. The exact tiers and what they represent are shown on your billing page.
Where it shows up
Your membership tier shows as a badge in the billing page header and in certain parts of the app interface. It doesn't affect plan limits or features — those are determined purely by whether you're on Free or Pro.
Does it change?
The member number is permanent and never changes. Tier may update over time as criteria are met. If your tier doesn't look right, use the Sync button on the billing page to re-fetch the latest data from the server.
