What does this policy cover?

We offer clinical services for people with long term respiratory conditions, such as Asthma and COPD, providing personalised treatment advice, help on-hand during disease flare ups or attacks, and regular follow-up (our “Clinical Services”). We also design, develop, operate and maintain a novel wearable medical device (“Smart Garment”) and software application (the “App”) to help people track their lung conditions, including for use in research projects and studies and with healthcare professionals. Where we or our partners run a research programme using our Clinical Services / Smart Garment / App and you sign up (through voluntary informed consent) to that research programme, we will collect and process data in accordance with the scope of activity for that research programme or project (which we or our partners will provide in writing prior to your agreeing to participate). Where one of our partners runs a research programme or project using our App, they will have access to your data for the purposes of that research programme or project.

If you have any questions regarding a research programme or project in which you are participating or the data being processed about you for that research programme or project, please contact the sponsor organisation for that research programme or project. Our Apps, Sites and Services may contain links to and from the online properties of our customers, partner networks, advertisers and affiliates or other third parties. If you follow a link to any of these online properties, please note that these online properties have their own privacy policies and that we cannot and do not accept any responsibility or liability for these policies.

Please check these policies carefully before you submit any personal data to these websites.

    • In response to requests by government or law enforcement authorities conducting an investigation.

Withdrawing consent or otherwise objecting to direct marketing

Wherever we rely on your consent, you will always be able to withdraw that consent, although we may have other legal grounds for processing your data for other purposes, such as those set out above.

Who will we share this data with, where and when?

Our Apps and Services are designed to help you track your data. They have additional value when used alongside your care team (medical, health or other professional), who may be our partner. There will also be opportunities to be part of research projects or studies. Access to the Senti Services may therefore be made available to you via one of our partners (for example, your GP may provide you with access).

In registering to use the Apps and Services, you will have used a unique registration code. This unique registration code links your Senti account to one or more of our online properties or to online properties of our partners. For example, your Senti account may be linked to a specific database for a research study or for a particular hospital or a doctor’s surgery.

  • Your data will be viewable by all professional authorised users of the online properties your account is linked to (researchers, site managers, doctors, nurses, practice managers, dieticians etc.).
  • Your data will not be viewable by other patient users unless you elect otherwise.
  • It may also be possible for your clinicians or health professionals to add data to your account (for example, a diary note, or a new task) as well as view any data you have entered.
  • We do, however, put you in control of your data, and will explicitly ask for your consent before any of your data is shared with one of our partners, or with your own care team. However you should be aware that this may affect how you and your clinicians and / or researchers use the Service.

If you have access to the Apps and Services via a Senti partner and that partner terminates its contractual relationship with Senti, you may no longer have access to the Senti Services via that partner. Data uploaded whilst using the Senti Services via the Partner may also no longer be accessible.

If you would like further information about whether you will have continued access to the Services following termination of our contractual relationship with the relevant partner, please contact

Personal data may be shared with government authorities and/or law enforcement officials if required for the purposes above, if mandated by law or if required for the legal protection of our legitimate interests in compliance with applicable laws.

Personal data will also be shared with third party service providers, who will process it on behalf of Senti for the purposes identified above. Such third parties include providers of website hosting, maintenance, call centre operations (if this is part of a specific project or programme in which you are participating) and identity checking services where this is an essential part of your project or programme.

In the event that the business is sold or integrated with another business, your details will be disclosed to our advisers and any prospective purchaser’s adviser and will be passed to the new owners of the business.

Where your data is stored.

User data is stored exclusively within the UK.

What rights do I have?

You have the right to ask us for a copy of your personal data; to correct, delete or restrict (stop any active) processing of your personal data; and to obtain the personal data you provide to us for a contract or with your consent in a structured, machine readable format, and to ask us to share (port) this data to another controller.

In addition, you can object to the processing of your personal data in some circumstances (in particular, where we don’t have to process the data to meet a contractual or other legal requirement, or where we are using the data for direct marketing).

These rights may be limited, for example if fulfilling your request would reveal personal data about another person, or if you ask us to delete information which we are required by law to keep or have compelling legitimate interests in keeping.

To exercise any of these rights, you can get in touch with us using the details set out below. If you have unresolved concerns, you have the right to complain to an EU data protection authority where you live, work or where you believe a breach may have occurred.

For registration into the Senti Services and the verification of your identity the provision of information is mandatory: if relevant data is not provided, then we will not be able to create a new account, register you into your study, project or programme or securely log you into an existing account. All other provision of your information is optional. However, if you do not provide your information your experience in using the Senti Services may be impaired and you may not receive the full benefit of using our Services, either individually, or with your healthcare professional or research team.

How do I get in touch with you?

We hope that we can satisfy queries you may have about the way we process your data. If you have any concerns about how we process your data, or would like to opt out of direct marketing, you can get in touch at

How long will you retain my data?

If you want to stop using your Senti account, you can either deactivate or delete it.

Deactivating your account puts your account on hold but we do not delete any of your information. You can deactivate your account by sending an email to with the subject heading ‘Account deactivation’. When you delete an account, it is permanently deleted from Senti. This process is irreversible. It typically takes us about 48 hours to delete an account, but some information may remain in backup copies and logs for up to 6 months. You should only delete your account if you are sure you never want to reactivate it. You can delete your account by sending an email to with the subject heading ‘Account deletion’.

Where we process personal data for marketing purposes or with your consent, we process the data until you ask us to stop and for a short period after this (to allow us to implement your requests). We also keep a record of the fact that you have asked us not to send you direct marketing or to process your data indefinitely so that we can respect your request in future.

We follow advice from the Department of Health and the British Medical Association on how long to keep information found in your medical records. This is called a ‘retention period’. We might also keep some information that doesn’t identify you to help improve our business and our services. In some circumstances, we might keep data longer if the law says we have to.

Where we process registration and clinical data, we do this for as long as you are an active user of our Services, Apps or Devices, and for 8 years after this. Where we process personal data in connection with performing a contract, a project or research study, we keep the data for 8 years from your last interaction with us.

We regularly update this policy

We keep this policy up-to-date. The last time this policy was reviewed was in December 2022
