  • 1. Information we collect

    We collect the following personal information about you in several ways:

    a) Information you provide to us when you register and use our Service

    This includes:

    • Registration information - when you register, we collect contact information such as your name, date of birth, email address and mobile number; information to authenticate you as an eligible patient such as your date of birth, NHS number, GP details and address, and to authenticate your access to the Service by way of a password for your sign-in security; and information required by the NHS, mostly not mandatory to answer, such as gender, ethnicity, religion to enable them to create a picture of services delivered around the country to check that quality standards are similar everywhere and the local demographic population is provided with adequate services (all reports published from this data are aggregated and contain no information that could reveal your identity).

    • Assessment information - we collect information using standard structured patient assessment questionnaires both to initially establish what treatment plan is likely to be beneficial to your needs, and on an ongoing basis prior to each session of your subsequent care. Assessment information can cover a range of factors relevant to your experiences and how you are feeling in addition to your medical history, lifestyle, family, work and education.

    • During the course of your treatment - This includes messaging between you and your therapist between sessions to arrange and provide you with information about your therapy sessions, the sessions themselves, the ‘homework’ activities and questionnaires completed, and the setting of goals. The sessions comprise a verbatim record of conversation between you and your therapist that are retained in the form of a transcript for text therapy or an audio file for video therapy, and which you can access through the account settings of the Service. This will include information relevant to and about how you are feeling at that point in time. You will be encouraged to record goals within your account, and we generate information about these treatment goals and assessment score graphs to help you and us to monitor and understand your progress

    • Any specific information required by NHS England and/ or contracts with our NHS payers. E.g., specific employment information for part of Improving Access to Psychological Therapies (IAPT).

    • Your queries or comments - we will collect information if you contact us for example with a question or comment about the Service and/ or its content. You always have the option to refuse to submit personally identifiable information to us but note that without this information, the Services may be unavailable to you.

    b) Information we collect from other sources

    We add to the information we collect from you with information we receive from other sources.

    This includes:

    • Referral information - from your General Practitioner (GP) or healthcare provider, if you are referred by them for treatment to Ieso and the Service. This will usually include your name, date of birth, address, mobile number, email address, NHS number, reason for referral and any relevant assessment notes and questionnaire scores.

    • Therapist notes - At the end of each session your therapist will produce a short set of clinical notes to summarise the session. For some of our NHS contracts, these summary notes are copied into your health record on your health care provider’s patient management system, but the verbatim records of sessions will never be copied over.

    • Supervision notes – a therapist may share some of your details with their supervisor per section 2 below and receive advice and /or feedback. Where this affects the treatment you receive, and/or the outcome, it makes up part of your medical record with us.

    • Demographic information - that is publicly available and that enables us to understand anonymous health statistics at postcode level.

    c) Information collected automatically from your use of the Service

    Certain information is collected automatically from your computer or device about your engagement with the Service.

    This includes:

    • Session activity information - we collect information about you from your use of the Service. (E.g., when you log on, accept an appointment, join a session etc.)

    • Device information - this includes information about whether you are using the service on a mobile, tablet or computer. This helps us understand how people interact with our service so that we can ensure the Service is optimised for different devices.

    • Log information - we collect technical information such as your Internet Protocol (IP) address, (the unique address that identifies your device or computer on the internet), your browser type and when, how often and for how long you interact with the Service.

    See here or read below for further information on cookies

  • 2. How we use collected information (includes sharing within Ieso, and our contracted therapists and Psychological Wellbeing Practitioners)

    We use the personal information we collect to ensure that we provide you with the best possible treatments both now and in the future. We have appointed a Data Protection Officer and Caldicott Guardian to seek to ensure that our procedures for handling patient information meet with our obligations.

    We use the personal and clinical information that we receive under our terms with you to:

    • Assess your suitability and eligibility

    • Register you with the Service - to consider requests for use of the Service and to enable sign-in and verified access and use of the Service.

    • Assess your treatment needs - to place you with an appropriate therapist, and to aid selection of exercises and questionnaires.

    • Provide your treatment - your personal information is shared with your therapist to support your treatment and evaluate your progress, including messaging to arrange sessions, conducting sessions, assessing progress against treatment goals and maintaining your case file. It’s your choice to decide what to share with your therapist, but the more information that your therapist has about you, the more likely it is that they will be able to provide you with highly effective treatment. Your therapist only has access to your personal information during your treatment and for 6 weeks after discharge to allow for reflection and/ or to consider any feedback from you.

    • Subject to appropriate safeguards, some of the details of your case may be shared in your therapist’s routine clinical supervision with their Clinical Supervisor if they wish to obtain advice or assurance on the work you are doing together. The British Association of Behavioural & Cognitive Psychotherapies (“BABCP”) requires that all therapists must receive clinical supervision. A Clinical Supervisor is a therapist who has received additional training and is generally more experienced than the therapist. This is to ensure that the therapy you are receiving is the most helpful it can be and remains faithful to best practice evidence. Clinical supervision includes case discussions (and may include referring to messages/ transcripts/ audio recordings) either individually or within a group of therapists, all of whom are bound by confidentiality.

    • Communicate with you

    • via email, phone or the messages section of your file between sessions if/ when appropriate, to confirm appointments, remind about incomplete questionnaires, about Service availability and related Service updates or notifications, or reply to your enquiries, requests or complaints.

    • via text message to remind you about upcoming appointments.

    • via voicemail (where you have agreed to this) for missing information or questionnaires.

    • via post at assessment and /or the end of treatment.

    • Where you have indicated to us on a questionnaire or in response to an email that you would be happy to share your experience of receiving therapy provided by Ieso to raise awareness of our service or for therapist training purposes, or to participate in some user experience evaluations, for example, we will use your contact details to give you more information. If you subsequently consent, we will process your information further for this purpose, which would include wider sharing of your personal data as agreed with you.

    • To let you know of any clinical trials/ studies for which you may be eligible (in which of course you can decline to take part).

    • We also contact you after you’ve completed treatment to ask for feedback and to check on your wellbeing.

    • Protect you and/or others - and seek to maintain a confidential and safe environment.

    These measures include:

    • user authenticated access controls to the service

    • restricted access to patient identifiable information. Access to patient records within Ieso is limited on a strictly 'need to know' basis and wherever possible processed by reference to indirect rather than directly identifying information, such as case reference numbers.

    • ongoing review of the care and help our professional therapists provide to make sure it meets our quality standards. This includes training, case management support, moderation, supervision and monitoring of messaging and treatment sessions.

    • developing learning/ training programmes for our therapists.

    • administering our professional compliance duties and obligations.

    • Uphold the NHS Opt-out service. We submit all patient NHS numbers to the ‘Check for National Opt-outs service’ in order to apply data opt-outs in accordance with patient wishes.

    • Conduct analysis and research to improve our service delivery, patient recovery rates, and service and/or product development. We are passionate about learning from these data by conducting high-quality scientific research to feed into treatment and product development to further improve outcomes and help more people get treatment earlier. We believe research can help provide a greater understanding of both the causes of mental illness and the effectiveness of treatments and interventions for different subgroups of patient. We may use that research to improve the Service, the Site and/or to develop new digital products to improve the assessment or treatment of mental health conditions. We have internal procedures in place to safeguard your privacy so that only the minimum necessary information is used to conduct the research on the most de-identified data possible, including anonymisation where possible.

    (We may anonymise patient data to use for new product development of products intended to help more people get treatment earlier. Although this is not then personal data, you may be interested in reading about an example of this research here.

    Much of our research is based on the NHS Minimum data set (see section 3 below), but we also use machine learning, natural language processing (NLP) and artificial intelligence (AI) on questionnaires, communications between you and your therapist, and on therapist summaries of the sessions. Click here for more information about this.

    • Determine whether or not a patient is eligible and suitable for participation in one of our clinical trials/ studies. We are data-driven research orientated company who passionately believe in responsible innovation to increase the understanding of mental health, improve treatments and widen access to treatment, and our clinical team may review your data to identify participants.

    We only ever share the minimum information necessary to provide the best treatments, care and protection for yourself or others, or to satisfy legal requirements. For example, depending on your referring healthcare provider, your data may be provided to update their records and/or as part of the Minimum Data Set required nationally by NHS England for all its patients. We have specific processes in place regarding verbatim records of sessions which are only shared internally or externally in very limited circumstances, for example we may facilitate joint viewing of/ listening to specific verbatim records of sessions with the contracting NHS service in the case of a serious upheld complaint, see section 3 'When we share your information'. We will always seek your permission before disclosing your personal identifiable information to another person or organisation for any other reason than those set out in these privacy notices, unless we have an overriding legal duty to so do (for example, in the prevention and/or detection of a crime).

  • 3. When we share your information

    We appreciate and respect that the confidentiality of your interactions with the Service are of utmost importance to you. Information is only shared on a strictly ‘need to know’ basis. Anyone receiving information about you will be under an equal legal duty to keep it confidential.

    The confidentiality of all information shared between yourself and your therapist is upheld to the highest level possible. We recognise that you may consider some information you give to us, and that may be recorded in the verbatim records of therapy sessions and/or messaging, as particularly sensitive. Relevant internal policies and procedures are designed to share the minimum information necessary to provide the best treatments, care and protection for yourself or others.

    In delivering the Service to you, your personal information may be shared with:

    • Your GP and/or your referring healthcare provider - Like all NHS service providers, it is important for us to work in collaboration with other healthcare professionals like your GP or your local psychological therapy service. This will be at the start and end of your treatment where we notify your GP or healthcare provider of the assessment and discharge, where the letter to the GP is sent by encrypted email (and where you also receive a copy of these letters), or where we transfer your care to another healthcare provider or refer you back to your original provider where an alternate provider is able to administer more appropriate care, where we provide them with a patient report so they have the details of your condition and the treatment provided by us. During registration we ask whether you are happy for your therapist to share information about your treatment with your GP and you may decline this. Some of our NHS contracts require us to update the referring provider’s patient management systems with information such as when you have sessions and clinical summaries of the sessions, and some also require audit meetings to review feedback which very occasionally may include the joint viewing of/ listening to specific verbatim records of sessions or messaging relating to any internal investigations that have been conducted by us as a result of a serious clinical incident or significant complaint during the year. We also update your referring healthcare service to enable invoicing and/or during the investigation of any serious clinical incidents.

    • NHS Digital - Providers of NHS-funded mental health services in England are required to provide a specified set of data (Minimum Data Set) to NHS Digital, who use this to create a picture of services delivered around the country to check that quality standards are similar everywhere. The data set includes NHS numbers, gender, age and ethnicity, but all reports published from this data are aggregated and contain no information that could reveal your identity.

    • We share minimum personal data with systems we use to process the data, your email address for automated emails, your case reference number if the case is discussed in supervision sessions, and your IP address. (See sections 5 ‘How we store your information’ and section 7 ‘Cookies and tracking’ below.) Outside the normal course of providing services.

    We also share the minimum necessary information where required or entitled by law, legal process, or professional ethical or law enforcement reporting purposes. This may include notifying appropriate authorities, regulators or law enforcement agencies, or allowing them confidential access to specific information as part of an inspection or review, or to prevent fraud or cybercrime or any threats. This would include the sharing of specific information required by government and/ or contracts with our NHS payers (e.g., specific employment information for the Department of Work and Pensions). If these circumstances arise, we will inform you wherever possible.

    Where you have indicated to us on a questionnaire or in response to an email that you would be happy to share your experience of receiving therapy provided by Ieso to raise awareness of our service or for therapist training purposes, or to participate in some user experience evaluations, we will use your contact details to give you more information and process your information further for this purpose if you subsequently give your consent, which would include wider sharing of your personal data as agreed with you.

    If you agree to leave a review of our service on an external site, then the process will include giving a name, email address, star-rating, comment and optional photograph to the 3rd party site e.g., Trustpilot, who will then be the controller of this data. The third-party will not receive any data before your agreement.

    In order to conduct research and development to improve treatment outcomes and help more people get treatment earlier, we sometimes partner with external researchers, e.g. university researchers or potential future commercial partners. When this happens, we ensure that they will be unable to identify anyone personally. All partners also sign a legal agreement that any data they receive is kept confidential and secure.

    Where you are accessing these services as part of a research project led by another organisation, you will have consented with them to share the relevant data back to them for their research. For the avoidance of doubt this will not include verbatim records of your therapy sessions.

    We have internal procedures in place to safeguard your privacy, so that only the minimum necessary information is used to conduct research and development on the most de-identified data possible. We will always seek your permission before disclosing your personal identifiable information to another person or organisation for any other reason than those set out in these privacy notices, unless we have an overriding legal duty to so do (for example, in the prevention and/or detection of a crime).

    Sharing your personal information without your agreement

    The sharing of information about you without your agreement is strictly controlled by law.

    In exceptional situations we may need to share information (only the minimum necessary) without your permission if:

    A serious crime has been committed

    Withholding information could endanger someone’s life

    A child or vulnerable adult is at potential risk or

    We are ordered to by a court of law

    In such circumstances, we would inform you wherever possible.

    Transferring data outside the UK, and holidays during treatment

    We seek where possible to prevent any transfers of your personal information to countries which have not been assessed as having adequate data protection standards.

    The European Commission makes decisions on the adequacy of the protection of personal data in third countries and have decided that personal data can flow safely between countries in the European Union, the European Economic Area (EEA), and other listed territories without any further safeguards being necessary. (

    Post UK departure from the EU, the UK has been granted adequacy by the EU, and the UK has accepted the European Commission’s adequacy decisions for the UK too, and also included Gibraltar.

    Accessing our Services when outside these territories is considered a transfer of data to a third country by data protection legislation. It is at your own risk if you decide to attend therapy sessions whilst you are visiting countries not listed at the web reference above. Our therapists are not permitted to access the Service from outside these territories, so will notify you of any necessary short breaks in your treatment due to travel.

    We will not sell your personal information for direct marketing or other promotional purposes.

  • 4. How we secure your information

    We place great importance on the security of personal identifiable information associated with our patients. We have put controls in place to safeguard the personal information that you provide, applying physical, technical and procedural measures against the loss, misuse and alteration of personal information under our control. All information submitted by you is encrypted in transit using best-practice Transport Layer Security (TLS) with at least 128-bit encryption. All clinical data is encrypted using the industry-standard AES-256 cipher and stored in Microsoft Azure, on secure servers in the UK, managed by Ieso.

    We have achieved the International Standard certification for information security (ISO 27001), Cyber Essentials Plus certification, and satisfy the requirements of the NHS Data Security and Protection Toolkit requirements.

    Remember also that you are responsible for keeping your password secret at all times when accessing and using the Service.

  • 5. How we store your information

    Ieso’s headquarters are in the United Kingdom (UK), and information about you submitted via the Services is used by us and hosted by our service provider, Microsoft Azure, on secure servers in the UK, managed by Ieso. As detailed in the Security section of these Privacy Notices, such information is stored in an encrypted state, both in transit and at rest, meaning the provider cannot lawfully access identifiable information.

    We use a small number of well-known SaaS (Software as a Service) providers to store subsets of your information and enable the uses of information described in these notices. We have Data Processor Agreements in place with each. Where possible these providers store the data in the UK or EEA. Where they are located outside the UK / EEA we ensure they are either party to an adequacy decision or have in place one of the additional safeguards necessary to make the transfer such as Binding Corporate Rules or Standard Contractual Clauses (with additional technological and organisational controls as necessary or appropriate) to uphold your legal data protection rights. 

    We retain your information and health record as a resource that you can return to for 20 years post discharge. This can help you remember coping strategies, techniques or processes that you learnt in therapy. If you were to experience a setback between sessions or after you’ve completed treatment, you may find it useful to refer to the transcripts/ audio recordings of your therapy sessions and messages. We retain your clinical record by reference to the NHSX Records Management Code of Practice and to support our legal obligations to be accountable for your care.
    The Code is based on current legal requirements and professional best practice.

    Research records and data are kept for a minimum of 20 years in accordance with Medical Research Council guidance.

    Our data retention practices are reviewed at least annually in conjunction with industry standards and best practice.

  • 6. Your access, rights and choices

    You can access specific details relating to your treatment through the Service online at any time directly through your account, these will therefore remain resources available to you after the conclusion of your treatment. These include messaging between you and your therapist between sessions, the sessions themselves, the ‘homework’ activities, questionnaires completed, and any goal setting activities. The sessions comprise a verbatim record of conversation between you and your therapist that are retained in the form of a transcript for text therapy or an audio file for video therapy. You can also update or amend some key registration and contact details directly through your account.

    If you feel there is an error of fact on your health record held by us, you can contact us, or in respect of your wider medical record your referring healthcare service or GP. If we or they agree the information is incorrect, the alteration will be made. If we or they are not satisfied the information is factually incorrect, a note will be made of the information you consider is inaccurate, and you will be notified of either the correction or the note.

    Data protection law also includes the right to data portability and to make other requests to seek to erase, object to and restrict personal data processing where certain limited grounds apply. Note however that data processed for health/treatment and legal purposes, or where other legitimate grounds for the processing apply, are examples of circumstances where some of these rights can be restricted or not apply in practice. Specifically, the right to erasure does not apply when processing is necessary for the provision of healthcare or the management of healthcare systems or service.

    If you need assistance or have an enquiry about accessing, updating or amending your records, or where applicable, about receiving or transmitting a file of the data you have provided (for example to your GP) please write to:

    The Data Protection Officer, Ieso Digital Health,
