Who we are

Ostler.Host is run by Anastasia Tattersall, a sole trader based in the United Kingdom. I’m the data controller for the information described here. You can reach me at ostler.host@gmail.com.

What we collect and why

• Waitlist sign-ups: your email address, so we can send you a welcome email and let you know when Ostler opens to founding hosts. We rely on your consent, and you can withdraw it at any time by replying to any email.
• Hosts: your contact details, the listing link you give us, and the property information you teach Ostler, so Ostler can answer your guests on your behalf. If you preview Ostler and choose not to sign up, your preview is deleted. Payments are handled by Stripe; we never see or store your full card details. We rely on our contract with you.
• Guests: the messages you send through your host’s Ostler link and the booking reference in that link, so Ostler can answer your questions and pass anything it can’t answer to your host. At the end of your stay, your host receives an email summary of the conversation. We rely on the legitimate interest of your host in looking after you during your stay.
• Emails you send us: your name, address and message, so we can reply.

We never sell your information or use it for advertising.

Who helps us run Ostler

We use a small number of trusted providers to run the service: Netlify (website and waitlist form), Google (email), Hostinger (the server that runs our automations), Anthropic (the AI that drafts Ostler’s replies), Telegram (messages between Ostler and hosts), Stripe (payments), Supabase (database) and Firecrawl (reading the public listing pages hosts give us). Some of these providers process data outside the UK; where they do, the transfer is protected by safeguards such as the UK International Data Transfer Addendum or standard contractual clauses.

How we use Google user data

Ostler uses Google’s Gmail API only to send emails from ostler.host@gmail.com, such as the waitlist welcome email, and to reply to messages people send us. We don’t read, analyse, share or sell Gmail data for any other purpose. Ostler’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

How long we keep it

• Waitlist email addresses: until you ask to be removed, or until Ostler stops operating.
• Host information: while you use Ostler, then deleted from Ostler as soon as you leave. Payment records are kept by Stripe and in our accounts for as long as the law requires.
• Guest conversations: once your stay ends, Ostler emails your host a summary of the conversation and then deletes the conversation from Ostler entirely.

Your rights

You can ask to see the information we hold about you, correct it, delete it, or object to how we use it. Just email ostler.host@gmail.com and I’ll reply myself. If you’re unhappy with how we’ve handled your information, you can complain to the Information Commissioner’s Office at ico.org.uk, or to the data protection authority where you live.

Changes

If we change how we use your information, we’ll update this page and the date at the top.
