Convert PlusThe SDEA product and packaging sustainability tool

Privacy notice

This notice explains what personal information Convert Plus holds and what we do with it. The tool is run by the Shop & Display Equipment Association (the SDEA), 24 Croydon Road, Caterham, Surrey CR3 6YR, which is responsible for your information.

What we hold

  • Your account: your name, email address, company and, if you give it, your phone number. If you sign in with your SDEA members' login, we link your account to your SDEA membership.
  • Your projects: everything you enter about your designs, and your company logo if you upload one.
  • Sign-in and usage records: when you sign in and which features you use (for example, downloading a PDF). For security, we briefly record the email address and internet address used for sign-in attempts.

We use one cookie, to keep you signed in. We do not use advertising or tracking cookies.

What we use it for

  • To provide the tool to you and keep it secure.
  • To send you emails about your account, such as password links. We do not send marketing from this tool.
  • To see how the tool is used, so we can improve it.
  • To show anonymous benchmarks: typical carbon figures for each type of project, worked out from many members' results. A benchmark is only shown when it draws on at least 5 projects from at least 3 companies, and never shows who they belong to.

We use your information because it is needed to provide the service you have asked for, and in our legitimate interest in running and improving it.

Who can see it

  • You, and colleagues at your company if your company has been set up to share projects.
  • SDEA staff who run the tool, and our website hosting provider, which stores it for us.
  • Anyone you send a share link to can see that project's results. You can switch a link off at any time.

We do not sell or pass on your information.

How long we keep it

We keep your account and projects until you delete them or ask us to. Sign-in attempt records are deleted after a day, and usage records after three years.

Your rights

If you are unhappy with how we have handled your information, you can complain to the Information Commissioner's Office at ico.org.uk.
