Your inputs stay on your device
Every calculation runs in your browser. What you type into a tool is not uploaded to, or stored on, any server.
Share links contain your inputs
As you use a tool, it writes your inputs (plot size, road width, project name and so on) into the page address. Share link copies that address.
- Anyone you send the link to sees those inputs.
- When the link is opened, the full address, inputs included, may appear in Netlify’s standard server logs.
- Chat and email apps that show link previews may fetch the address and see the inputs too.
Leave out anything you don’t want shared, such as a client’s name, before you copy the link.
No accounts, cookies or tracking
Plinthly has no sign-up, sets no cookies, does not use browser storage, and runs no analytics or advertising trackers.
Usage count
The homepage shows how many bylaw checks and conversions have been run. To keep that count, the first time you change an input on a tool, the page sends one word naming the tool (for example “bylaws”). Our server adds 1 to that tool’s total and keeps nothing else.
No inputs, results, identifiers or anything about you or your device are sent with it. The request reaches Netlify like any page request, so it may appear in the same standard server logs.
Third parties
- Google Fonts supplies the typefaces. Your browser requests them from Google, which receives your IP address as part of that request.
- Netlify hosts the site and keeps standard server logs (such as IP address, page requested and time) to run and protect the service.
