Steady keeps everything on the client's own phone or computer. There's no account, no server, no analytics and no tracking. Steady doesn't send client data to us, or to you.

01What Steady is

Intended purpose: Steady is a self-help tool for adults (18 and over) in recovery from alcohol or drugs, for tracking and reflection. People use it to count their days without using (called clean, sober or substance-free, as they choose), log uses and urges, keep morning and evening routines, write a plan for hard moments, work through the Twelve Steps or self-management worksheets, note appointments, and reach helplines.

It supports recovery. It isn't treatment or medical advice, and it isn't a replacement for professional support. It doesn't diagnose, treat, cure or prevent any condition, and it gives no dosing or tapering advice.

02Where the data goes

The client's phone or computer Steady, and all their records Optional PIN lock A backup file Only if the client saves one Their own calendar Only says "Appointment" Calls and links Open the phone or browser Lightkeeper Studio, or your service

03Data protection

Our understanding, for your data protection officer to confirm. We don't receive, store or have access to any client's records. Your service doesn't receive them through Steady either. So:

  • Neither Lightkeeper Studio nor your service processes clients' records through Steady. The client holds them, on their own device.
  • There's no data processing agreement to sign for the app itself, because there's no processing on your behalf.
  • A subject access request to us or to you can't include Steady records, because neither of us holds any.
  • If you recommend Steady, note it in your own records as you would any self-help resource. Your DPO may still want a short screening note for your DPIA log.

Privacy policy: in the app (Settings > About) and on the website. It's the same text in both places.

What we do hold: for organisations, the contact and invoicing details you give us (names, work email, address, purchase order). For individuals who buy Steady Plus, the payment company handles the purchase. A licence key never contains a client's name or anything about them.

04Medical device and clinical safety

05Safety and safeguarding

Steady isn't monitored. Nobody sees what a client enters, so it can't raise an alert. It must never be part of a risk plan in place of human contact.

06Security

NetworkThe app's security policy blocks all network requests. The Windows app also refuses every outside connection, and a test checks it makes none. The Android app asks only to show notifications, to keep reminders after a restart, and for the standard internet permission that the app framework includes. It sends nothing.
PIN lockOptional, but setup recommends one. New PINs are 6 to 12 digits. It locks the app after the person has been away, and the PIN itself is never stored, only a salted hash (PBKDF2-SHA-256, 150,000 rounds).
Records on the deviceWith a PIN, the records are encrypted on the device with a random key of their own (XSalsa20-Poly1305, from TweetNaCl). That key is encrypted with one made from the PIN (PBKDF2-SHA-256, 150,000 rounds, random salt), so the PIN is needed to read them, and we never have it. When records are first encrypted, the Windows and Android apps also clear old, readable copies from their own files. A forgotten PIN can't be reset, so without a backup the records are gone for good, and the app says so. Without a PIN, the records aren't encrypted.
BackupsA file the client saves themselves. An ordinary backup isn't encrypted, and the app tells them to keep it private. With Steady Plus (Security+), they can lock it with a password: it's encrypted on the device with AES-256-GCM, using a key made from the password (PBKDF2-SHA-256, 600,000 rounds, random salt). The password isn't kept anywhere, so a forgotten one can't be recovered. Opening a locked backup is always free. No backup includes the PIN.
Damaged or doctored dataEvery record is checked when it's loaded. Anything damaged is set aside, never run, and never lost. Safety copies are kept when records are repaired or restored.
Licence keysChecked on the device against our public key. No internet is needed, and nothing is reported back.
UpdatesThrough Google Play, and new installers for Windows.
TestingMore than 450 automatic checks of the app and website: records never lost, damaged backups can't break the app, safety warnings show, nothing connects out, and more.

09Summary against the NHS DTAC areas

The NHS Digital Technology Assessment Criteria (DTAC) cover five areas. This is a short summary, not a full DTAC submission. We'll complete the full form if you need it.

AreaSummary
Clinical safetyNot a medical device or clinical system (section 4). Safety wording and signposting throughout (section 5).
Data protectionNo personal data is collected, by us or by you, through the app. Everything stays on the client's device (sections 2 and 3). ICO: no data protection fee is needed (the ICO's own checker, October 2026).
Technical securityNo network access, records encrypted with a PIN, checked records and automatic testing (section 6).
InteroperabilitySteady doesn't connect to other systems, by design. Clients can save their own backup file, and add appointments to their own calendar.
Usability and accessibilityPlain English, three text sizes, light and dark mode, small screens, and a published accessibility statement. An independent audit isn't done yet (section 7).
