Privacy

The short version

Certificates you create in the Certably app stay on your device. We never receive one unless you submit it to your own firm for a supervisor to review, which is a firm feature you have to sign in to use — the rest of this page says exactly what that sends. On this website, the only personal data we hold is an email address, and only if you hand us one. We count which pages get visited, without a cookie and without knowing who you are.

Counting visits

We record which pages are opened, and whether the App Store button or the firm reservation form was used. That is the whole list. We do not record what you type, we do not record your screen, and we do not use your IP address — it is discarded in your browser before anything is sent, so we never learn where you are.

There is no cookie and nothing is kept once you close the tab, so we cannot recognise you on a second visit and cannot follow you to any other site. That is also why there is no cookie banner: there is nothing to ask you to agree to.

The counting is done by PostHog on servers in the EU. It is the one thing on this site that talks to anyone else — the fonts and Apple's download badge are served from our own domain precisely so that nothing else does.

What we collect on this site

If you reserve a firm workspace we store the firm name, your name, your email address, the seat band and billing period you chose, and the scheme you told us about if you told us one. We use it to set your workspace up and to contact you about it, and nothing else. Ask us and we delete it.

We ran a pre-launch waitlist until the app was released on 5 August 2026. That form is gone. If you gave us an email address for it we still hold that address and will use it once, to tell you the app is out — email privacy@certably.co.uk and we will delete it instead.

Downloading the app tells us nothing about you. Apple reports aggregate numbers to us and never who you are. What the app itself counts once you open it is set out below.

The free calculators run entirely in your browser. Nothing you type into them is sent to us or stored anywhere.

What the app collects — Electrical and Complete

Nothing off your certificates. Certificates, customer records, site details, photographs and test results are held on your device. If you enable iCloud sync they move between your own devices through your own Apple account, encrypted, and we have no access to that either.

What we do count. From version 1.4 the app records how it is being used: which kinds of certificate get started and finished, whether you looked at the PDF, which section of a form stopped you from issuing, and whether the subscription screen was shown. It is counted against a random identifier generated on your device — you are never asked to sign in, so there is nothing to tie it to you.

What it never carries is the part that matters: no client or site name, no address, no photograph, no signature, no free text you typed, and no test result of any kind — not a Ze, not a Zs, not an insulation reading, not rounded and not put into a range. A measurement belongs on the certificate you signed and nowhere else. That is enforced by a test in the app's own source, not by a promise: any value containing a digit is rejected before it can be sent.

The counting is done by PostHog, on the same EU servers as the website counting described above. Screen recording is switched off in the app and will stay off — it would capture client names and readings straight off the screen.

Subscriptions are handled by Apple. We never see your payment details or your name and address.

Your calendar. Certably can add a certificate's next inspection date to your calendar, and — only if you turn it on separately — read today's appointments so it can offer to start the certificate one of them describes. Both happen on your device. Your diary is never uploaded, never sent to us, and never sent to anyone else. The app works exactly as well if you say no to both.

Where Certably reads an appointment, it fills in the site and the client and nothing else. It never fills in a test result from anything other than what you measured and typed.

What the app collects — Firms

The Firms plan is different, and we are not going to blur it. A Qualified Supervisor cannot review a certificate that only exists on somebody else's phone, so certificates, customer records, site details, photographs and test results sync through a Certably workspace that we operate.

That data is held in the UK, encrypted in transit and at rest, and isolated to your firm. We do not sell it, mine it, share it with third parties, or use it to train anything. Your firm can export all of it in a machine-readable format at any time, and we delete it on request when you leave.

Firms plans use named accounts, so we hold each engineer's name and email address, and a log of certificate actions — created, submitted, reviewed, signed or rejected — because that audit trail is the point of the product.

Your rights

Under UK GDPR you can ask us for a copy of the personal data we hold about you, ask us to correct it, or ask us to delete it. Because the most we hold is a firm reservation or an old waitlist email address, this is usually a one-line request. Email privacy@certably.co.uk and we will action it within 30 days.

You can complain to the Information Commissioner's Office at ico.org.uk if you think we have handled your data badly.

Changes

If this policy changes in a way that affects you, we will say so on this page and email anyone whose address we hold before the change takes effect.
