Privacy and saved setups

Analytics and cookie choices

We use Plausible and Google Analytics to understand which pages and tools are useful. Measurement includes page visits and actions such as using a tool or following a product link.

Tool events use fixed action categories. They do not include purchase amounts, placement answers, dates, notes or refill history.

Plausible counts every visit without cookies. It may receive browser and device information and a referring page.

Google Analytics is run by Google, which receives the page address, the actions we measure on this site and browser and device information, and sets cookies that tell repeat visits apart. Its advertising features are off.

In the European Union, Iceland, Liechtenstein, Norway, the United Kingdom and Switzerland, and whenever we cannot tell which country a visit comes from, Google Analytics loads only after you choose Accept on the bar at the bottom of the page. Decline loads nothing from Google. Your choice is kept in this browser for six months, then the bar asks again.

Elsewhere, Google Analytics loads with each page unless you choose Decline. Cloudflare, which delivers our pages, tells your browser which country the visit comes from.

Wherever you are, Cookie choices at the bottom of any page, or the button below, changes your choice. Decline stops Google Analytics on this site in this browser and deletes its analytics cookies. If analytics was running, the page reloads to apply your choice. Decline holds on every page; outside the countries above it is kept until you change it.

We send both services the page address without its query string or fragment, and Google gets no referring address. Both receive your IP address with each request.

Cookie choices

Cookies and visitors in the EEA and the UK

Saved setups and refill history use storage on your own device, which never leaves it and which you can clear from My setup or in your browser settings.

Google Analytics sets its cookies only where it loads, as described above, and never for advertising. Plausible sets no cookies at all and does not follow you between sites.

If you are in the European Economic Area or the United Kingdom, Google Analytics loads only after you choose Accept, and Cookie choices at the bottom of every page changes your answer. We hold no account, no profile and nothing that identifies you, so there is no profile to export, correct or delete. Write to us through the contact page with any privacy question and we will answer it.

Third parties that can receive request data when you use this site: Google Analytics and Plausible as described above, Amazon when a product photograph loads or you follow a retailer link, and the manufacturer or retailer whose link you follow. If a display advertising network is added later, this page will name it and describe its consent mechanism before the first advertisement appears.

Your saved details

Saved setups use storage on this device. Public share links contain product choices, not your setup name or private details. Printing and downloading a backup leave private values out unless you select the option to include them.

Outside links

Following a retailer or wildlife-information link takes you to a service with its own privacy terms. Our tools never send your private estimates to retailers.

Retailer links on this site are affiliate links: they carry a tracking code so the retailer can attribute the referral and pay us a commission. As an Amazon Associate I earn from qualifying purchases. The commission costs you nothing and changes no recommendation on this site; the affiliate disclosure page lists which links can earn one.

Product photos

Product photos load directly from Amazon’s image service. That service receives your IP address and normal browser request information when a photo loads. Selecting a product photo opens its corresponding Amazon product page.

Keep, restore or clear your data

Browser data can be cleared or lost. Download a backup if you want a copy, and keep files containing private values somewhere appropriate. Restoring a backup previews the setups and adds them alongside your existing work. You can clear saved setups and refill history from My setup. Never enter a router password or an exact home address in these tools.

Contact messages

The contact form sends your report, your reply address and any page or source you add through Cloudflare. Cloudflare Turnstile runs an automatic security check that never asks you to solve anything; it receives your browser and connection details to tell people from automated senders.

We keep each report in our contact inbox at Cloudflare for 12 months, then it is deleted automatically, and a copy goes to a private Discord channel our team reads. We use your reply address only to answer you, never for marketing. To stop floods of messages, the form counts reports from one connection or reply address for two hours, under a one-way code rather than the address itself.

To see or delete a report you sent, ask through the same form and we will delete both copies. Please do not include passwords, account logins, payment details or your home address.
