Privacy

What runs on your device only

The bending maths itself is local: the rise, angle, depth and take-up you type are worked in your browser and are never transmitted. A few things are kept in your browser's local storage, and they stay there unless you sign in:

• your imperial or metric choice (bentright.system), whether you picked it or it was picked for you (bentright.system.src), and the older bentright.unit key, kept in step so nothing breaks;
• a private tally of which calculators you open, so your most-used can show first (bentright.recent);
• the calculators you pin, the order you put them in, the ones you hide, and any lists you make (bentright.mytools);
• any bender take-ups you choose to save on a calculator (bentright.takeup);
• the bender table you fill in on measure your bender — its take-up, gain, notch and springback figures (bentright.bender);
• the address you typed into "Email me" under a calculator (bentright.sendto), kept after a first send so you do not have to type it again — the send itself is covered below.

One more is the exception: a random visitor id (bentright.vid) is kept in the same place but is also sent with each page view, so the section on what the site records is where it really belongs. Clearing your site data removes all of them.

Units and sending results

On your first visit we ask Cloudflare which country the request came from, only to pick imperial or metric for you. It isn't stored. Change it any time with the Imperial/Metric switch.

"Email me" under a calculator sends the sheet — what you typed, the results and a link that reopens the calculation — as one email from bentright, through our mail provider, to the address you type. We keep that address only if you tick the box to join the list; otherwise it is used for that one email and not stored. What the send log keeps is which calculator, when, and a salted hash of the address (the same hash counts sends toward a limit of five an hour) — not your numbers and not the address. If the address is already on file for an account or the list, the send is simply logged against it. Copy, Text it, Share and Print never leave your device.

If you make an account

An account is optional and never required. If you sign in — with a one-tap email link, no password — we store your email address and your synced preferences (units, most-used, pinned tools and lists) so they follow you between your devices. The sign-in link is sent through a transactional email provider on our behalf. Your email is used to sign you in and, if you opt in, for the occasional note when a new tool goes up. Sign out or ask us to delete the account and it is gone.

If you add a work profile

Signed-in tradesmen can optionally leave a short "looking for work" profile — trade, location, contact details and a note. If you do, we store it so we can pass suitable work leads to you or reach out ourselves, and we may share it with employers looking to hire. Don't add one and none of that applies; ask and we'll delete it.
