Privacy policy

Last updated 26 October 2026

Tiny House Grove (tinyhousegrove.co.uk, "we") is a directory where UK tiny house builders, and people selling their own tiny homes, list them and buyers get in touch. This policy explains what personal data we handle, why, and what you can ask us to do with it. Questions or requests: [email protected].

Tiny House Grove is run by Hollowfin, a sole trader, which is the controller for the data described here. Hollowfin is registered with the Information Commissioner's Office, registration number ZC275968.

If you send a seller a message

You don't need an account. We collect your name, email address, phone number (optional), your message, any answers you choose to give about budget, timing, land and payment, and the page you sent it from.

We use it to pass your message to the builder or private seller you contacted: we email it to them and show it in their inbox on this site. Our lawful basis is legitimate interests: you asked us to put you in touch. The seller then has your details and is responsible for how they use them, as a separate controller.

We may email you once, a little while after you sent your message, to ask whether the seller got back to you. It's a single question about your enquiry, not marketing, and you don't have to reply. It helps us make sure sellers on this site answer buyers. Our lawful basis is legitimate interests.

To stop spam, the form has hidden checks that catch automated messages, and we limit how many enquiries can be sent from one connection in a short time. We don't store your IP address for this.

If you sell on Tiny House Grove

We collect your email address and, if you give it, your name. If you sign in with Google or Microsoft, we receive your name, email address and an account ID from them; we never see your password. There are no passwords on this site: you sign in with Google, Microsoft or a one-time email link.

If you're a builder, your shop details, logo, models and photos are shown publicly, because that's the point of a shop page. If you're selling your own home, your listing, its photos, the town or area you give and the first name you choose ("Listed by Sam") are shown publicly; your full name and contact details aren't. The email address that enquiries go to is never shown to buyers.

We use this data to run your account and listings, and to send you enquiries. Our lawful basis is contract: it's the service you signed up for. Sold listings stay online, marked as sold, until you delete them.

Everyone

We count page views per page per day so builders can see how their pages are doing. These counts are just numbers: no cookies, no IP addresses and nothing that identifies you. Our servers keep standard logs, which include IP addresses, for up to 14 days to keep the site secure and fix faults.

We don't show adverts, use analytics trackers or sell your data. We don't send marketing emails to buyers. We may email builders and sellers about their pages and listings, for example to check that a home is still for sale; tell us if you'd rather we didn't.

If we contact your business

We sometimes contact tiny house businesses to ask whether they'd like a page here, using the contact details they publish themselves. We keep the business name, those contact details and a note of what was said, so we don't contact you twice. Our lawful basis is legitimate interests. If you ask us to stop, we will, and we keep only a note not to contact you again.

Who else handles your data

We use a few companies to run the site. They act on our instructions and only for these purposes:

• Hetzner (Germany): hosts the site, database and photos.
• Postmark (ActiveCampaign, USA): delivers the site's emails: sign-in links and enquiries to sellers.
• Cloudflare (USA): our network and domain, and our backups (encrypted before they leave our server, so Cloudflare can't read them).
• Google Workspace (USA): our email inbox, including messages you send to [email protected], and our working documents, such as our record of which businesses we've contacted.
• Google and Microsoft: only if you choose to sign in with them.

Where data goes to the USA, it's protected by the UK–US data bridge or the UK's standard contract clauses. We may also share data if the law requires it.

How long we keep it

• Enquiries: 24 months from when they were sent, then deleted automatically.
• Copies of emails we've sent: 90 days.
• Sign-in links: they expire after 15 minutes and are deleted within a day.
• Builder accounts and shops: until you ask us to delete them.
• Addresses a builder has blocked: as long as that builder's shop exists, so the block keeps working.
• Server logs: 14 days. Backups are encrypted and replaced within 30 days.

Cookies

We only use cookies the site needs to work, so there's no cookie banner:

• a sign-in cookie that keeps builders signed in, for up to 30 days;
• a security cookie that protects forms from being sent by other websites;
• short-lived cookies while you sign in with Google or Microsoft, and for one-off messages like "Saved".

Your rights

You can ask us for a copy of your data, to correct it, to delete it, to restrict or object to how we use it, or to send it to you in a reusable format. Email [email protected]; we reply within one month. If you sent a builder an enquiry, you can also ask them directly, since they hold a copy too.

If you're unhappy with how we've handled your data, please tell us first. You can also complain to the Information Commissioner's Office at ico.org.uk or on 0303 123 1113.

Changes

If we change how we use your data, we'll update this page and the date at the top. Builders will hear about significant changes by email.
