LOTOwerx Privacy Policy

Contact: sales@mtccrane.com

LOTOwerx is a mobile app for writing OSHA 29 CFR 1910.147 lockout/tagout procedures. This policy explains what we collect, why, and your choices.

Information we collect

  • Account: the name and email you use to sign in, your sign-in id, and whether you accepted the in-app disclaimer. Sign-in uses email and a password. We also store the shop (organization) name, your role, and any site name or address you enter.
  • Procedure and equipment content: equipment identifiers you enter (name, asset tag, manufacturer, model, serial number, location), procedure text (title, purpose, energy sources, isolation points, steps, and related program fields you fill in), version history, approvals (including the signer’s name, role, and signature), periodic inspection records, and training records (including names you enter).
  • Photos: photos you take or attach of equipment, nameplates, isolation points, and optional locked-and-tagged photos. These stay on your phone until you sign in. After you sign in, they are backed up to our private storage so your shop can share procedures.
  • Contacts to notify before lockout: the name, role, and phone number you enter for people who should be told before a lockout. These can appear on a published placard page if someone uses a live QR link.
  • AI scan: if you use the optional AI equipment scan, the machine photo, nameplate photo, and any nameplate text you typed are sent to a third-party image recognition service so the app can suggest procedure details. You review those suggestions before they become part of a procedure. We also keep a record of the scan session and of whether you accepted, edited, or rejected each suggestion.
  • Purchases: if you buy a plan in the app, payment is handled by Apple. We use RevenueCat to learn your plan status (for example, the free plan, the one-time Asset Pack, or Unlimited) and remaining scan credits. We do not receive your full Apple ID password or card number.
  • Device permissions: camera (equipment, nameplates, isolation points, and placard QR codes) and photo library (optional).
  • Technical: basic app and sign-in session data needed to keep you signed in and operate the service (via our backend providers).

How we use information

  • Provide and improve procedure writing, PDF and placard export, QR links, team sharing, and optional AI scan features.
  • Authenticate accounts and let people in your shop see the procedures and records shared with that shop.
  • Apply plan limits and restore purchases you already made.
  • Respond to support requests.

Sharing

We do not sell your personal information. We use service providers who process data only to run LOTOwerx, including hosting, sign-in, and database (Supabase), Apple App Store distribution and in-app purchases, RevenueCat for purchase status, and a third-party image recognition service when you run an AI scan.

People you add to your shop can see shared equipment, procedures, photos, contacts, and related records for that shop.

A signed placard can include a QR code that points to https://loto.mtccrane.com/p/<short id>?t=<token>. Anyone with a live link can read the latest approved revision, including equipment name, location, energy sources, isolation points, steps, and the notify-before-lockout contacts on that procedure. Turning the link off issues a new token, and the old QR code stops resolving.

Shop-printed placard orders, when offered, open the MTC Crane website with a request code and the procedure link.

Retention & deletion

We keep account and procedure data while your account is active. You can delete your account in the app or by emailing sales@mtccrane.com.

If you are the only member of a shop, deleting your account also deletes that shop’s procedures, photos, and related records, and turns off its public placard links. If other people remain in the shop, the shared shop records stay for them. Your login is removed, and scan records that belong only to you are deleted.

Some records may remain in backups for 30 days after account deletion.

Canceling an Apple subscription is done in your Apple ID subscription settings. That is separate from deleting your LOTOwerx account.

Your choices

  • Update your profile details in the app.
  • Delete your account in the app or by contacting us.
  • Control camera and photos in iOS Settings.
  • Turn off a procedure’s public placard link so an old QR code no longer opens it.

Children

LOTOwerx is for workplace use and is not directed to children under 13.

Changes

We may update this policy. We will post the new effective date on this page.
