Trenvoy Privacy Policy

Last updated: 13 July 2026

Trenvoy is operated by Total Business Consultants Ltd ("we", "us"), a company registered in England and Wales. This policy explains what information Trenvoy handles, why, and your rights over it. We've written it in plain English on purpose.

The short version

Trenvoy is a quoting tool for trade professionals. We store the information you put into it — your business details, your customers, your jobs and quotes — so the app can do its job. We don't sell your data, we don't show adverts, and we don't use your data to train anything. Connections to your accounting software happen only when you set them up, and you can disconnect them at any time.

What we collect and why

Your account. Your name, email address and a password (held by our authentication provider in hashed form — we never see it). Used to sign you in and secure your data.

Your business profile. Company name, logo, contact details, VAT registration status and number, labour rates, parts markup and quote terms. Used to produce your quotes and invoices correctly.

Customer and job data you enter. Names, addresses and contact details of your customers, and the jobs, scopes and quotes you build for them. This is your data about your customers: for it, you are the data controller and we act as your processor — we store and process it only to provide the service to you. You are responsible for having a lawful basis to hold your customers' details, exactly as you would with a paper diary or spreadsheet.

Quote links. When you send a quote, your customer receives a private web link. These links use long, unguessable addresses; anyone with the link can view that quote (that's how your customer opens it without an account). Withdrawing a quote disables its link.

Accounting connections (QuickBooks, Xero). If you connect your accounting package, we store the secure connection tokens on our servers — never in your browser — and use them for one purpose: creating invoices in your own accounting package when you press the button. We never see your accounting password. Disconnecting in Settings stops all access. Your use of QuickBooks or Xero remains subject to their own terms and privacy policies.

Technical information. Standard server logs (for example IP addresses and error reports) used to keep the service running and secure. We do not use advertising or analytics trackers.

Where your data lives

Trenvoy runs on established cloud infrastructure: our database and authentication are provided by Supabase and our hosting by Vercel. Data may be processed in the UK, EU or US by these providers under their standard contractual safeguards.

How long we keep it

For as long as you have an account, plus a short period afterwards to allow reactivation. You can ask us to delete your account and its data at any time; we will do so, subject to anything we must keep by law (such as billing records).

Your rights

Under UK data protection law you can ask us for a copy of your personal data, ask us to correct it, ask us to delete it, or object to how we handle it. Email us and we'll act on it. If you're unhappy with our answer you can complain to the Information Commissioner's Office (ico.org.uk).

Cookies

Trenvoy uses only the cookies needed to keep you signed in. No advertising cookies, no third-party trackers.

Security

Data is encrypted in transit; access to production systems is restricted; customer-facing quote output is structurally separated from your internal cost data; accounting tokens are held server-side where your browser — and anyone else's — cannot read them.

Changes

If we change this policy in a way that matters, we'll tell you in the app or by email before it takes effect.
