Privacy Policy

Cleanroom Control, by Coll Business Solutions LLC. Last updated October 17, 2026.

Cleanroom Control is a touchscreen controller and online app that companies use to monitor and run their cleanrooms. This policy explains what information the service collects, how it's used, and the choices you have. "We" and "us" mean Coll Business Solutions LLC. "Your company" means the business whose account you use.

Information we collect

Account information

Information from your controllers

On the controller's memory card

The controller has a slot for an optional microSD memory card. If one is put in, the controller also keeps on it the room's readings and a backup of how the room is set up: device names, areas, alarm limits, fan schedules and similar settings. The backup never includes the Wi-Fi password, the screen PIN or the controller's cloud identity. What's on the card stays on the card in the room: it isn't sent to us or anywhere else. Anyone who has the card can read it, so take the card out, or erase it, before a controller is given away or sent for repair. A factory reset erases this controller's readings and settings backup from the card.

Records of what happens

Support provider information

If your company adds a support provider, such as the company that installed your cleanroom, we store that link. When someone at your company clicks Request help, we store who asked, when, and the note they wrote.

A support provider can upload its logo and choose to show its name, phone number and logo to the companies it supports. When it does, they appear on those companies' emails and reports and on their controllers' wall screens.

Logos

Logos uploaded by a company or a support provider are shown in emails and reports, so each one can be opened by anyone who has its link, without signing in. Only upload a logo you are happy to have seen this way. Removing a logo stops it being shown.

Phone notifications

If you turn on notifications in the phone app, we store a device token so notifications reach that phone.

What we don't collect

The app keeps your sign-in in your browser's local storage so you stay signed in. Signing out removes it.

How we use information

Who can see your information

We don't sell your information or share it with advertisers.

Service providers

A few outside services process data for us, each only to do its job:

These providers may not use your data for their own purposes.

Storage and security

Data is stored in a managed database and sent over encrypted connections. Each controller has its own secret key and can only send and receive its own room's data. Passwords are hashed, and sign-in sessions expire. Any user can turn on two-factor sign-in, and a company owner can require it for everyone in the company. Each user's role limits what they can change.

How long we keep information

Your choices and requests

Admins can edit and remove users, rooms, alarm limits and certification files in the app. Any user can change their name, email address and password, and turn two-factor sign-in on or off, on the Account page. If someone loses the phone they use for two-factor sign-in, the company owner can reset it so they can set it up again; the reset is recorded in the activity log and the person is told by email.

The company owner can delete the whole company account in the app: Account page, then Delete company account. That removes every user, room setting, alarm, activity log entry, certification, maintenance record and recorded reading, and frees the controllers to be added to another account. It doesn't erase a controller's memory card; take the card out or erase it separately.

To ask for a copy of your data, or to delete a single user account, email collbusinesssolutions@gmail.com from the address on the account. We'll confirm by email once it's done. Some records may be kept longer if the law requires it, and we'll tell you if that applies.

Children

Cleanroom Control is a workplace tool and isn't directed at children.

Changes to this policy

If this policy changes, we'll post the new version here with a new date. For important changes, we'll also let account owners know by email.
