Privacy Policy

AcoustaPLOT Ltd (company number 17389299, registered office 81 Howarth Road, Wimborne, Dorset, BH21 2FG) is the data controller for information collected through acoustaplot.com.

Room data: the dimensions and surface materials you enter to run a check or generate a report. Order data: your email address and order reference, so we can send you your report and answer questions about it. Payment data: none of it — payment is handled through Stripe Managed Payments, with Sold through Link LLC acting as merchant of record, who takes your card details directly; we never see or store them. Echo is supplied and sold by AcoustaPLOT Ltd. Contact data: anything you send us through the contact page or by email. Nurture-email opt-in data: if you tick the separate, optional box on the free-check result screen, we keep the email address you give us and a snapshot of that one result, so we can send you the two follow-up emails you asked for.

We use three tools to understand how the site is used. Google Analytics (Google) counts visits and which pages and buttons are used. Microsoft Clarity (Microsoft) records anonymised page interaction such as clicks, scrolling and heat maps. All three are switched off until you press Accept on the cookie notice, and they are not loaded at all if your browser sends a Global Privacy Control signal or you press Decline. Google Analytics and Microsoft Clarity set cookies on your device when on. The third tool, Vercel Analytics, counts page views without cookies or personal profiles, and also only runs after you press Accept. We do not run advertising trackers, and we never pass room details, names or email addresses to these tools. We also keep a small signed cookie that remembers your country for pricing, and a setting that remembers your cookie choice in your browser.

What is sent. If you use ‘Ask about your report’, the question you type and the figures for your own room (room type, dimensions, the standard checked against, the target and predicted reverberation time, and the result) are sent to an AI model so it can answer. We do not send your name, email address or order reference with them.

Who handles it. The request goes through Vercel's AI Gateway to an AI model from a provider that Vercel lists as offering zero data retention. For every question we ask the Gateway to use zero data retention, which is intended to mean the provider does not keep the question or the answer after replying or use them to train its models. We are still checking the provider's own terms to confirm this, and we will update this page when we have. If zero data retention cannot be requested, the question is not answered. Because the provider and Vercel may process data outside the UK/EEA, the safeguards in section 6 apply.

What we keep. We do not store your question or the answer in your account. Our hosting provider's ordinary server logs (for example the time of the request and any error) may be kept for a short period for security and debugging. The AI can make mistakes; please check anything important.

Room and order data: to perform the contract when you buy a check or report (necessary for performance of a contract). Contact data: to respond to you (legitimate interest in providing support). We don't use your data to build a profile of you for advertising, and we don't sell it.

Stripe Managed Payments, with Sold through Link LLC acting as merchant of record (to process payment and handle tax), our hosting provider (to run the site and store report data), our email delivery provider (to send your order confirmation and cancellation-rights notice — your email address and the content of that email pass through it), and — once it's live, not yet — the provider behind the contact assistant, for questions you choose to ask it. If you opt into the nurture emails described above, the same email delivery provider sends those too. No one else, and never for their own marketing purposes.

Our hosting infrastructure and our email delivery provider may each process data outside the UK/EEA. Where they do, this is covered by appropriate safeguards (such as Standard Contractual Clauses or the UK International Data Transfer Addendum) required under UK/EU data protection law.

Orders: six years. When you buy something we keep a record of it — the room you bought a report for, your order reference, your email, and the cancellation confirmation we are required by law to send you. We keep that for six years, which is roughly how long someone could bring a claim about a contract. (Separately, the download links for a £34.99 report and for the one-off Studio and Pro analyses, the Acoustic Brief, the Design Decision Pack and the speaker and building services tools stay open for three years.) We keep it because we have to (a legal obligation) and because you would want us to.

Your Studio account and saved projects: for as long as your account is active. If you have Echo Studio, your account record and the projects and rooms you save in it stay yours to come back to for as long as the account exists — cancelling a subscription does not delete them, so re-subscribing later picks up where you left off. If you want the account itself deleted, ask us (see "Your rights" below) and we will remove it, other than anything we are separately required to keep as part of an order record above.

The free check: not stored at all, unless you ask us to email it to you. If you run the free check and don't buy, the dimensions and materials you entered are used to work out your figures and are not written to any database. The one exception is the separate, optional "email me this result" box on the result screen: if you tick that, we keep your email address, your result, and which room type it was for, so we can send you the two follow-up emails you asked for. You can unsubscribe at any time with the one-click link every one of those emails carries — doing so does not delete the record that you asked to stop, so we don't accidentally email you again.

We are not building a library of your projects to sell or mine, and we don't keep anything indefinitely for its own sake.

You can ask to access, correct, delete, or receive a copy of your personal data, and you can object to how we use it, by emailing echo-support@acoustaplot.com. If you're not satisfied with our response, you have the right to complain to your local data protection authority — in the UK, the Information Commissioner's Office (ico.org.uk).

We'll update this page when what we actually do changes, and update the date at the top when we do.
