Privacy Policy

Last updated

This policy explains how Trident Maples LLC (“we”, “us”) handles personal information for NC Proof: the website ncproof.com, the apps at app.ncproof.com and your NC Proof account.

The short version: we keep what we need to sign you in, bill your plan and answer your messages. Your G-code programs stay in your browser. We do not sell your information and we do not use advertising trackers.

What we collect

Information Why we use it
Email address Your account: sign-in codes, receipts, important notices about your plan.
Sign-in records: when each browser signed in and was last used, the browser and system type (from the browser’s user agent) and the approximate country Keeping you signed in, the 3-device limit, and spotting shared or stolen accounts.
IP address Limiting how many sign-in codes can be requested, to stop abuse. Kept for up to 2 days.
Plan and billing status: plan, trial and renewal dates, the customer and subscription IDs from our payment provider Knowing whether your plan is active. Card details are handled by Stripe; we never see your full card number.
Messages you send us through the Contact form or by email: name, email address, message Answering you.

What we do not collect

  • Your G-code programs. The apps process them in your browser. They are not uploaded to our servers.
  • No advertising or cross-site tracking cookies, and no selling or sharing of personal information for advertising.

Cookies and browser storage

  • One sign-in cookie on app.ncproof.com keeps you signed in for up to 90 days. It cannot be read by scripts.
  • Local storage in your browser keeps your app settings and your licence, so the full apps keep working offline for up to 7 days.
  • The apps store their own files in your browser (a service worker cache) so they open quickly and work offline.

You can clear all of this at any time in your browser settings; you will then need to sign in again.

Who helps us run NC Proof

We share information only with service providers that need it to run NC Proof, under their own privacy and security terms:

  • Cloudflare: hosting for the website and apps, the account database, and delivery of email sent to our domains;
  • Resend: sending sign-in codes by email;
  • Stripe: payments, subscriptions, receipts and tax;
  • our email provider for [email protected].

We may also share information when the law requires it, to protect our rights or users’ safety, or as part of a sale or merger of the business (the new owner would have to respect this policy).

How long we keep it

  • Account and sign-in information: while you have an account. Sign-in records for signed-out browsers are deleted.
  • Billing records: as long as tax and accounting law requires.
  • Messages: as long as needed to help you, and then up to 2 years.

If you ask us to delete your account, we delete your account information within 30 days, except what the law requires us to keep.

Your choices and rights

You can ask us to show you, correct or delete the personal information we have about you, or to stop emailing you anything other than sign-in codes and plan notices. Write to [email protected] from the email address on your account. Depending on where you live (for example California, or the EU and UK), you may have further rights under local law; we will honour them. We will not treat you differently for using these rights.

Security

Sign-in codes expire after 10 minutes and are stored only as one-way hashes; sessions are stored the same way. Connections are encrypted (HTTPS). No system is perfectly secure, so please keep your email account safe.

Children

NC Proof is for working machinists and businesses. It is not meant for children under 16, and we do not knowingly collect their information.

Where information is processed

We are based in the United States. Our service providers may process information in the United States and other countries where they operate.

Changes

If we change this policy, we will update the date below and, for important changes, tell you by email or with a notice in the app.
