Site analytics and cookie choices
We use two measurement services to see which pages and tools people use: Plausible Analytics (Plausible Insights OÜ, European Union) and Google Analytics 4 (Google LLC, United States). They receive page-view information and a small set of named actions, such as running a calculator, opening a result, downloading a plan or following a link to a retailer.
These requests include browser and connection information, including your IP address. We send Google a page address without its query string, fragment or referring address, and never turn on its advertising features.
Plausible measures visits without any identifier that follows you between sites, and can report time spent and scrolling. We send it a page address without its query string or fragment.
Your schedule times, plan names and free-text labels are never included in what we send.
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.
Who else receives data, and why
Google LLC (Google Analytics 4) for page and action measurement. Google's privacy policy is at policies.google.com/privacy.
Plausible Insights OÜ for cookie-free page measurement, hosted in the European Union.
Amazon.com Services LLC, when your browser loads a product photograph from Amazon's image service or you follow a link to an Amazon listing. Amazon receives the connection information needed to serve the image or the page, including your IP address, and applies its own privacy notice and cookies once you arrive.
If a display advertising network is added to this site in future, this page will name it and describe what it receives before the first advertisement is served.
If you are in the EEA or the UK
Plausible measurement runs on our legitimate interest in understanding which pages and tools are used, and sets no identifier. Google Analytics loads only after you choose Accept on the bar at the bottom of the page, and you can withdraw that choice at any time under Cookie choices. We do not sell or share personal information, and we run no profiling or automated decision-making.
You can ask what we hold, ask for it to be corrected or deleted, or object to measurement. Use the contact page. Because we hold no account for you, a request usually has to be matched to a specific page visit and time before we can act on it.
Measurement data is retained by Google for 14 months and by Plausible in aggregate form without an expiry. Browser storage created by the planner stays on your device until you clear it.
Saved plans and preferences
The schedule planner saves only when you choose Save on this device. A saved plan stays in this browser storage until you delete it or clear site data. Other people using the same browser profile can see it. Browser restrictions can prevent saving; the tool reports that and still lets you download the plan.
Retailer and manufacturer links
If you follow a link to a retailer, that website handles the visit under its own privacy policy. Amazon links carry our affiliate tracking id so the sale can be attributed to this site; they carry no information about you, your schedule or your plan. Manufacturer reference links are untagged.
Product photographs
When a product photo is available, your browser loads it from Amazon's image service and the photo is itself a link to the Amazon listing. Amazon receives the connection information needed to deliver it, including your IP address. Nothing you enter into a tool on this site is attached to these image requests.
Contact and corrections
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 never include passwords, payment details or private information about a child. This site publishes no contact email address.
