How SleepNav works – and why this notice is short

SleepNav is a clinical decision support system for community pharmacy sleep services. It was designed from inception to operate without patient-identifiable data. Patients complete a screening on a pharmacy tablet; the app generates a short alphanumeric code that encodes their clinical responses. The pharmacist enters the code into the SleepNav CDSS, which provides an evidence-based recommendation. At no point does any patient name, date of birth, address, NHS number, or other personal identifier enter the system.

This is not a limitation or a gap in development. It is a deliberate architectural decision that implements the data minimisation principle of UK GDPR Article 5(1)(c): the system achieves its clinical purpose without personal data, so none is collected. As a result, SleepNav does not require a Data Protection Impact Assessment for patient data, does not require a Data Processing Agreement between Snorer.com Ltd and your pharmacy, does not require NHS Information Governance approval, and cannot be subject to a Subject Access Request, court order, or law enforcement enquiry for patient-identifiable information – because none exists.

This Privacy Notice therefore addresses only the personal data of pharmacist users of the CDSS. It is short because the data processing is simple: one data controller (Snorer.com Ltd), one category of data subject (pharmacists), and no patient data.

Who we are

Snorer.com Limited is the data controller for the personal data you provide when using the SleepNav Clinical Decision Support System (CDSS). Our contact details are:

Snorer.com Limited
4 Waterford Lane, Cherry Willingham, Lincoln, LN3 4AL
Email: contact@sleepnav.com
Company registration: 08144806
ICO registration: Z3279480

What personal data we collect

When you register for and use the SleepNav CDSS, we collect and process:

  • Your name, email address, and GPhC registration number (provided at registration)
  • Your pharmacy premises association
  • Login activity and session data (timestamps, IP addresses)
  • Consultation activity (screening codes decoded, recommendations viewed, consultation outcomes selected)
  • Knowledge Navigator queries (question text and response metadata)
  • MFA credential data (encrypted TOTP secret, hashed backup codes, hashed session PIN)
  • Billing and payment data (managed by eeZed Ltd via Stripe; Snorer.com Ltd does not store card details)

What we do not collect

SleepNav does not collect, store, or process any patient-identifiable data. No patient names, dates of birth, addresses, NHS numbers, or other personal identifiers enter the system at any point. Screening codes encode clinical variables only – they cannot be linked to any identified or identifiable patient by Snorer.com Ltd or by anyone with access to the CDSS.

This means that, unlike health technology platforms that hold patient records, SleepNav:

  • Cannot be subject to a patient Subject Access Request (there is no patient data to disclose)
  • Cannot be subject to a court order or law enforcement request for patient information (there is nothing to produce)
  • Does not require your pharmacy to sign a Data Processing Agreement with Snorer.com Ltd for patient data
  • Does not require a Data Protection Impact Assessment for patient data processing
  • Does not require NHS Information Governance or ICB approval for deployment
  • Does not create data breach notification obligations for patient data (there is no patient data to breach)
  • Does not impose data retention or deletion obligations on your pharmacy for records held within SleepNav

The clinical record of care – including the patient’s identity and the decisions you make – belongs in your pharmacy’s Patient Medication Record (PMR), where it is protected by your existing professional obligations and governance arrangements.

Why we process your data (lawful basis)

We process your personal data on the following legal bases:

Contract (Article 6(1)(b)): Processing your account data, consultation records, and billing information is necessary for the performance of the contract between Snorer.com Ltd and your subscribing pharmacy premises.

Legitimate interests (Article 6(1)(f)): Processing login activity, session data, and usage analytics for service security, quality improvement, and abuse prevention. Our legitimate interest is maintaining a secure and reliable clinical decision support service. This does not override your rights – the data processed is limited to what is necessary for service operation.

Legal obligation (Article 6(1)(c)): Retaining billing records as required by HMRC (6 years).

Who we share your data with

eeZed Ltd (company number 07907333): Billing administrator. Processes subscription and screening charges via Stripe on behalf of Snorer.com Ltd.

Stripe: Payment processor. Handles card details and payment transactions. Snorer.com Ltd does not store your card details. Stripe’s privacy policy applies to payment data.

Voyage AI: Knowledge Navigator queries are processed using Voyage AI’s embedding API to retrieve relevant clinical guidance. Query text is sent to Voyage AI for embedding generation. No patient data is included in queries. Voyage AI’s data processing terms apply.

Where your data is stored

Your account data and consultation records are stored on servers in the London region (DigitalOcean, London data centre). Billing data is processed by Stripe (data centres in the EU/UK).
