Privacy notice

What this site does

The public pages provide editorial information and an in-browser calculator. Calculator values remain in your browser and are not submitted to us. We do not offer accounts, comments or an email signup form, and we do not set advertising or analytics cookies.

External links

Clicking an external website sends you to that provider, whose own privacy and cookie policies apply. Clearly marked affiliate links include a tracking identifier so the provider can attribute a qualifying sale.

Click measurement

We record a page-view event and clicks on affiliate recommendation buttons in our own site database. A record can include the event type, page path, timestamp, referring hostname, campaign labels from the link and, for an affiliate click, the merchant and offer. We do not store your name, email address, full referring URL, cookie ID or advertising ID. If your browser sends Do Not Track, these events are not sent.

Purpose, legal basis and retention

We use these limited records to understand which editorial pages and Pinterest campaigns are useful and whether recommendation buttons are working. The legal basis is our legitimate interest in improving this small editorial service and measuring its business performance. Event records older than 90 days are deleted automatically. Cloudflare processes technical hosting data as our infrastructure provider.

Your choices

You may enable Do Not Track in your browser or email us to object to this limited measurement. Affiliate merchants may measure visits and sales after you leave this site under their own policies.
