Privacy policy
Last updated: 19 October 2026
Who we are
Assist Street Ltd is a company registered in England and Wales (company number 17518103), based in London ("we", "us"). We are responsible for the personal information collected on this website, including through the chat assistant on it. Contact us about anything in this policy at hello@assiststreet.co.uk.
This policy covers the Assist Street website. When our assistant runs on one of our clients' websites, that business decides how its customers' information is used, and its own privacy policy applies. We process that information on its behalf, under a data processing agreement.
What we collect
- Chat messages you send to the assistant, and its replies.
- Contact details you choose to give us, such as your name, email address, phone or WhatsApp number, and the details of your enquiry.
- Voice messages, if you use the microphone in the chat. Your recording is sent to Google's Gemini API to be written down as text, and we keep only the text, never the recording. Replies may be read aloud by your own device.
- The language you write in and a short summary of your enquiry, created automatically so we can reply.
- Limited technical information: a scrambled (hashed) version of your IP address, used only to stop spam and abuse, and deleted automatically after a few days. We never store your IP address itself.
We don't use advertising or analytics cookies. The chat keeps a conversation reference in your browser tab so it can continue your conversation; it's removed when you close the tab.
How we use it, and why we're allowed to
| Use | Lawful basis |
|---|---|
| Answering your questions and replying to your enquiry | Legitimate interests (responding to people who contact us), or steps before entering into a contract with you |
| Preventing spam and abuse of the chat | Legitimate interests (keeping the service secure and available) |
| Keeping a record of our conversation | Legitimate interests (handling your enquiry properly) |
We don't sell your information, and we don't use it for marketing unless you ask us to keep in touch.
Who helps us run the service
We use these providers to run the website and the assistant. They process information only to provide their service to us:
- Vercel: website hosting.
- Supabase: our database, where conversations and enquiries are stored.
- Google (Gemini API): the AI model that reads your messages and writes the assistant's replies.
- Resend: sends us an email notification when you leave your details.
Some of these providers store or process information outside the UK, including in the United States and Singapore. Where they do, we rely on the safeguards the law allows, such as the UK's International Data Transfer Agreement or standard contractual clauses, where the provider offers them.
How long we keep it
We keep conversations and enquiries for up to 12 months after our last contact with you, then delete them, unless you become a client, in which case we keep what we need to provide our service and meet legal obligations. Hashed IP addresses used for spam protection are deleted automatically after a few days.
Your rights
You can ask us to give you a copy of your information, correct it, delete it, restrict how we use it, or object to how we use it. Email hello@assiststreet.co.uk and we'll respond within one month.
If you're unhappy with how we've handled your information, please tell us first. You can also complain to the Information Commissioner's Office (ICO) at ico.org.uk/make-a-complaint.
Changes
If we change this policy, we'll update it here and change the date at the top.
