Privacy notice
Last updated 15 October 2026
The short version
Zuffi keeps your reminders, chats, contacts, leads and money records on your own devices. We only hold what we need to run your account and subscription.
What we hold, and why
- Your email address — to sign you in with a code and to link your subscription. (Contract)
- Your devices — a random device ID, the device name and type, and when it was last used, so you can manage up to 3 devices. (Contract)
- Your subscription — plan, status and renewal date, received from Paddle. We never see your card details. (Contract)
- Built-in AI usage — how many questions you asked this month, so we can apply the monthly limit. We don’t store the questions or answers. (Contract)
Who we share it with
- Paddle — our reseller and Merchant of Record, for payments, tax and invoices.
- Our AI provider — when you use the built-in AI (Pro and Business), your question is sent to the provider to get an answer.
- Our email provider — to send your sign-in codes.
- Our hosting provider — which runs this website and its database.
Linking your devices
When you link Zuffi Business across devices, your business data travels between them through a relay, encrypted on your device (AES-256). The relay and Lisan Systems can’t read it.
How long we keep it
We keep your account while you use Zuffi. If you ask us to delete it, we delete your account and devices within 30 days. Paddle keeps payment records as the law requires.
Your rights
You can ask for a copy of your data, ask us to correct or delete it, or object to how we use it: email lisansystems257@gmail.com. You can also complain to the Information Commissioner’s Office (ico.org.uk).
Who is responsible
Lisan Systems [Ltd], [registered address], is the controller of this data.
