Site owner FAQ

Is it really free?

Yes. The widget is free for personal and commercial sites as long as the "Powered by MyPollenPal" attribution link stays visible.

Will it slow down my site?

No. The widget is an iframe — it loads on its own in the background and doesn't block your page from rendering. No external JS to install.

How often does the data update?

Pollen levels refresh daily. The iframe is cached for an hour, so repeat visitors see the latest data without hammering our servers.

What if my city has no data yet?

We cover hundreds of US cities and add new ones daily. If your city shows no data, it'll usually populate within 24 hours once someone visits the city page.

Can I use it on a commercial site?

Yes. Blogs, health sites, HVAC companies, landscapers, local news — all welcome. Keep the attribution link and you're good.
