How it's measured →1.0%
of downloads still active
At least 400 of 38.1K lifetime downloads are still running, below its category: the median Security plugin keeps 1.4%, across 1,001 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Security plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.

What to do about it
- Add “no captcha” to your wp.org tags. You already rank #21 for it without listing it. WordPress.org counts only your first five tags, so it's a slot worth spending.
- One page off on “safety”. #13 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.

Estimated value
What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.
Est. annual revenue
Est. acquisition value
No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.
