Privacy notice

Who we are

MarginTrove is operated by Tessora LLC, 30 N Gould St Ste N, Sheridan, WY 82801, United States. Tessora LLC is the controller of the personal information described in this notice.

You can contact us about anything in this notice, or about how we use your information, at hello@margintrove.com.

This notice covers two situations: when you send us a request through this website, and when we email a UK business to ask about how it handles profit and costs.

When you send a request through this website

We receive your name, your email address, your store's web address, the revenue range you choose if you choose one, and anything you write in the message box.

The form is not for financial data. Please do not send sales figures, cost data or files through it. If you go ahead with an audit, we agree separately by email how that data is shared and handled.

The website itself does not store your request. It passes it on as an email to our mailbox and keeps no copy.

We use these details to reply to your request, decide with you whether an audit is a good fit, and arrange it if you go ahead. Our lawful basis under UK GDPR is taking steps at your request before entering into a contract, and our legitimate interest in responding to business enquiries. We do not add website enquiries to a mailing list.

When we email your business

MarginTrove is a new, paid service. To find out whether it is useful, we send a small number of individually written emails to UK Shopify brands. These emails ask a short question about how a business handles profit and costs and, where it seems relevant, tell you about our paid audit. They are business marketing emails, not academic research.

We only email UK limited companies and limited liability partnerships, at business email addresses they publish on their own website. We do not cold-email sole traders or ordinary partnerships.

Where the information comes from: your company's own website, the public Companies House register, which we use to confirm the company is registered and active, and the public advertising libraries run by Meta and Google, which show whether a brand currently advertises.

What we record: the company name and website, the published business email address and the page where it appears, publicly visible facts about the business such as its product range and delivery terms, and the date and status of our emails. We do not record directors' names or personal email addresses. If you reply, we also hold your name, your email address and what you write.

Our lawful basis is legitimate interests: contacting businesses that may benefit from a profit review, and learning what they need before we build more. We have written down how we balanced that interest against your rights. That reasoning relies on the emails going only to business addresses, being few and individually written, asking for no business figures, and stopping as soon as you ask. Legitimate interests is not a basis we can rely on once you object.

If you do not reply, we may send one short follow-up about a week later. We do not send further messages after that unless you reply.

Who handles your information

Emails we send and receive, including requests from this website, are handled by Zoho Mail, which stores them in the European Union. The website is hosted by Hetzner Online GmbH on servers in the European Union. Our list of companies contacted and the status of each email are kept in a private repository hosted by GitHub, Inc. in the United States.

We use AI assistants from OpenAI and Anthropic, both based in the United States, to help research publicly available information about businesses and to help write, send and manage our business emails. This means the emails we send, and any replies, are processed by these assistants. We send all business emails from our own mailbox, hello@margintrove.com.

These providers act on our instructions. We do not sell your information or share it with anyone else for their own marketing.

International transfers

Tessora LLC is based in the United States, and our team works from outside the United Kingdom. Your information is therefore accessed from outside the UK, our research records are stored in the United States, and our AI assistants may process emails in the United States. Each provider processes information under its own data processing terms.

How long we keep it

We keep website requests and business email correspondence for up to 12 months after our last contact with you, then delete them. If you become a client, records related to the work are kept for as long as the law requires.

The do-not-contact list is kept for as long as we send business emails, because deleting it would mean we could contact you again.

This website does not use analytics, advertising trackers or cookies, and our emails contain no tracking pixels. Our hosting provider keeps standard technical logs, such as IP addresses, to run and protect the site. To limit abuse of the form, the site also counts requests per IP address in memory for ten minutes. That count is never written to disk or linked to what you send.

Your other rights and complaints

You can ask us for a copy of your information, ask us to correct it, or ask us to delete it. Email hello@margintrove.com and we will respond within one month.

If you are unhappy with how we have handled your information, please tell us first at hello@margintrove.com. We will acknowledge your complaint within 30 days and tell you what we are doing about it.

You can also complain to the UK regulator, the Information Commission (formerly the Information Commissioner's Office), at ico.org.uk.
