Terms

Use WhenToBird for your own birding as much as you like. Don't copy it in bulk.

The data

WhenToBird is provided as is. The dates and percentages are summaries of past eBird checklists, not predictions or guarantees; birds and weather do what they like. Do not rely on this site for safety or for access to private land, and follow local rules at every location.

Fair use, no scraping

You may use the site and the app for personal, non-commercial birding: read, search, plan trips, print a plan, and share links. Without our written permission you may not:

scrape, crawl, bulk-download or systematically copy our pages, the files under /data/, or our API, whether by script, bot, browser extension or by hand;
use what you collect to build or feed another dataset, product, map, app, or to train or ground an AI model;
get around rate limits, blocks or paid features, or share an account to do so.

Search engines may index public pages as robots.txt allows. We may rate-limit or block traffic that looks automated, and close accounts that break these rules (refunding any recent purchase). For research, a club project or commercial use, email hello@whentobird.com; we are glad to talk about a licence.

The underlying bird records are not ours to lock up: they come from the eBird Observation Dataset (Cornell Lab of Ornithology) under CC BY 4.0, and anyone may get them from eBird or GBIF on those terms; see methods for the citation. These rules cover WhenToBird's own compilation, calculations, text, design and service.

Purchases

Lifetime is a single payment for access to paid app features for as long as the service operates; it will never be converted into a subscription. Nothing renews or charges you later.

Refunds: within 30 days of buying, refund it yourself in the app under Account, Purchases (one self-serve refund per account per year), or email hello@whentobird.com. Refunding Lifetime ends it; refunding an unredeemed gift cancels its code.

Gifts: a gift code gives whoever redeems it Lifetime (Trip Pass codes sold before November 2026 still give 30 days). It never renews and never charges them.
