Who we are

Shufflow is an early-stage productivity app, designed with ADHD in mind and built by a small team in the UK. Shufflow is run by Tianhui Zhu, who is the data controller responsible for the personal information described here. In this notice, “we”, “us” and “our” mean Tianhui Zhu and the Shufflow team.

If you have any questions about your information, email us at hello@shufflow.uk.

What information we collect

We only collect what you choose to send us through this website. When you request a demo or send an enquiry, we receive:

  • your email address
  • what you write in your message, such as a little about you and how you’d like to use Shufflow
  • which form you used and when you sent it

You don’t need to tell us anything about your health, and we ask you not to include it. If you do, we’ll only use it to reply to you and won’t keep it longer than we need to.

Like most websites, our hosting provider may also record basic technical information, such as your IP address and browser type, to keep the site running and secure.

To keep spam out, our forms use Cloudflare Turnstile. It looks at technical signals from your browser, such as your IP address, to check that a person rather than a bot is sending the message. It isn’t used for advertising.

How we use your information

  • to reply to your message
  • to arrange and run a demo, if you asked for one
  • to keep a record of our conversation with you
  • to keep this website working and secure

We won’t add you to a mailing list or send you marketing unless you ask us to. We never sell your information.

Our lawful basis

Under UK data protection law, we rely on our legitimate interests in responding to people who contact us. When you ask for a demo, we also rely on taking the steps you asked for before any agreement is made.

Who we share it with

We use a small number of trusted service providers. They can only use your information to provide their service to us, and must keep it safe:

  • Cloudflare hosts this website, runs the spam check on our forms and delivers your message to our inbox
  • Google stores the messages we receive and the replies we send (Gmail), and a simple record of each request in a private spreadsheet so we can follow up (Google Sheets)

We don’t share your information with anyone else unless the law requires it.

Information stored outside the UK

Cloudflare and Google may store or process information outside the UK, including in the United States. When they do, we rely on suitable safeguards, such as the UK International Data Transfer Addendum or the UK Extension to the EU–US Data Privacy Framework.

How long we keep it

We keep your message and email address for up to 12 months after our last contact with you, and then delete them. Rows in our follow-up spreadsheet are deleted automatically after 12 months. You can ask us to delete your information sooner at any time.

Keeping your information safe

We limit who can see your messages to the people who need to reply to you, and we use secure, password-protected services to store them.

Your rights

You have the right to:

  • ask for a copy of the information we hold about you
  • ask us to correct anything that’s wrong
  • ask us to delete your information
  • object to, or ask us to limit, how we use it

To use any of these rights, email hello@shufflow.uk. We’ll reply within one month.

Analytics and cookies

We use Cloudflare Web Analytics to understand how many people visit this website, which pages they look at and how quickly pages load, so we can make the site better. It only gives us totals, such as the number of visits from each country or browser. It doesn’t use cookies, doesn’t store anything on your device to recognise you, and isn’t used for advertising or to build a profile of you. Cloudflare provides it on our behalf.

Our lawful basis for this is our legitimate interest in improving our website. If you’d rather not be counted, you can turn analytics off for this browser here. If your browser sends a Global Privacy Control signal, we treat that as turning it off too.

To remember that choice, we save a small note in your browser’s storage. It contains no personal information and is used for nothing else. This website doesn’t use advertising cookies.

Questions and complaints

If you’re unhappy with how we’ve handled your information, please tell us first at hello@shufflow.uk so we can try to put it right.

You can also complain to the Information Commissioner’s Office (ICO), the UK’s data protection regulator, at ico.org.uk/make-a-complaint.

Changes to this notice

We may update this notice as Shufflow grows. When we do, we’ll change the date at the top of this page.
