The house rule

No retroactive paywalls. Features in your tier stay in your tier. We won't move something you already use behind a higher price — not after a redesign, not after a funding round. New features may launch in new tiers; the ones you pay for today don't move. And the price you start at is the price you keep for as long as your subscription stays active.
