Health App Data Sharing Agreement Checklist

Yes, if your health app shares patient, clinical or wellness data with clinics, labs, analytics providers or technology suppliers, you should have a written data sharing agreement in place.

The nuance is that not every data relationship is the same. Sometimes you and the other party are both controllers. Sometimes they're your processor. Sometimes you're jointly deciding what happens to the data. The right document depends on that role split.

Health and wellness data can be highly sensitive, and much of it will be special category data under the UK GDPR and the Data Protection Act 2018. A good agreement helps you show the ICO, partners and users that you have thought carefully about consent, security, retention and transfers before data starts moving.

Do You Need A Data Sharing Agreement For A Health App?

Yes, in most health app collaborations, you should have a data sharing agreement before you share identifiable health or wellness data.

The UK GDPR doesn't use the exact phrase data sharing agreement as a mandatory label for every situation. But it does require you to be accountable for how personal data is used, shared and protected, including through your privacy policy. For processors, Article 28 of the UK GDPR requires a written contract with specific terms, often handled through a data processing agreement. For joint controllers, Article 26 requires a transparent arrangement setting out each party's responsibilities.

In practice, if your app shares data with a clinic, pathology lab, remote monitoring provider, AI triage tool, cloud hosting provider or customer support platform, you need a document that clearly answers:

• What data is being shared
• Why it's being shared
• Who decides how the data is used
• What lawful basis and special category condition applies
• How users are told about the sharing, including in your health app privacy policy
• How the data will be secured, retained and deleted
• What happens if there's a data breach

Without this, you may find it hard to pass due diligence with clinics, investors or NHS-adjacent partners. You may also struggle to show the ICO that your business had proper controls in place if something goes wrong.

This doesn't have to be a heavy, 80-page document. For many startups, a clear, tailored agreement that matches the actual data flow is much more useful than a long template that doesn't quite fit.

Who Is The Controller, Processor Or Joint Controller?

It depends on who decides the purpose and means of using the data. This role mapping is one of the first things to get right.

Under the UK GDPR, a controller decides why and how personal data is processed. A processor acts on a controller's instructions. Joint controllers decide those purposes and means together.

Here's how this can look in a health app context:

• Your app as controller, supplier as processor: you collect symptom data from users and instruct a cloud provider to host it only for your service.
• Clinic and app as independent controllers: a clinic sends appointment outcomes to your app, and each party uses the data for its own separate purposes.
• Joint controllers: you and a clinic jointly design a remote monitoring pathway, decide what data to collect and decide how alerts will be handled.
• Supplier as separate controller: a lab receives samples and patient details, then uses the data to perform regulated testing under its own obligations.

Getting this wrong can create real problems. If you call a party a processor when they're actually deciding their own purposes, your contract may not match reality. If you treat a joint controller arrangement like a simple supplier contract, users may not know who is responsible for privacy notices, data rights requests or breach communications.

A practical way to map roles is to ask four questions:

• Who chose to collect this data?
• Who decides the reason for using it?
• Who decides how long to keep it?
• Who can share it with someone else?

Your agreement should match those answers, not just the bargaining power of each party.

What Should A Health Data Sharing Agreement Include?

A health data sharing agreement should spell out the data flow, the legal basis for sharing, each party's responsibilities and the controls around special category data.

Here is a practical outline you can use as a starting point. It isn't a finished legal document, and a lawyer should tailor it before you use it, especially where patient data, clinical workflows or international suppliers are involved.

1. Parties And Roles: name each organisation and state whether each is a controller, joint controller or processor.
2. Purpose Of Sharing: describe the specific reason for the data flow, such as remote monitoring, lab testing or technical support.
3. Data Categories: list the personal data, health data, device data, identifiers and any pseudonymised data being shared.
4. Lawful Basis And Special Category Condition: record the Article 6 lawful basis and Article 9 condition relied on by each controller.
5. Transparency And User Notices: set out who gives privacy information to users and when it will be provided.
6. Instructions And Limits On Use: say what the recipient can and can't do with the data, including any ban on secondary use.
7. Security Standards: cover encryption, access controls, audit logs, staff access, testing and incident response.
8. Data Subject Rights: allocate responsibility for access, erasure, objection and rectification requests.
9. Breach Notification: set reporting timelines, escalation contacts and evidence requirements.
10. Retention And Deletion: state how long data is kept, when it's deleted and what must be returned at the end.
11. Subprocessors And Suppliers: control when third parties can be used and what flow-down terms are required.
12. International Transfers: identify overseas transfers and the transfer mechanism, such as an adequacy regulation, IDTA or UK Addendum.
13. Audit And Records: set out what records each party keeps and when audit evidence must be provided.

Templates often miss the parts that matter most for digital health, such as role mapping, special category conditions, clinical escalation boundaries and secondary use of data for product development.

How Should You Deal With Consent And Special Category Data?

You need both a lawful basis under Article 6 of the UK GDPR and a separate special category condition under Article 9 where health data is involved.

Health data is special category data because it can reveal highly sensitive information about a person's physical or mental health. That doesn't mean you can never use it. It means you need to be precise about why you're using it and what legal condition allows it.

For health apps, common possibilities include:

• Explicit consent: often used where users actively choose to share health information with your app or a partner.
• Health or social care purposes: may apply in certain clinical contexts, usually where appropriate confidentiality duties apply.
• Scientific research: may apply for genuine research projects, with safeguards under the Data Protection Act 2018.

Consent needs careful handling. User consent for medical treatment, marketing consent and UK GDPR explicit consent aren't always the same thing. If you rely on explicit consent for special category data, it should be clear, specific, informed and easy to withdraw.

Your agreement should say:

• Who collects consent, if consent is being used
• What wording or consent journey is approved
• How consent records are stored
• What happens if a user withdraws consent
• Whether withdrawal stops future sharing only or triggers deletion of existing data

Say Priya runs a menopause support app with 12,000 UK users. Her app shares selected symptom scores with a partner clinic for virtual consultations. The app originally collected 15 data fields, but the clinic only needs 6 for the consultation. Priya's agreement limits sharing to those 6 fields, records explicit consent in the app, and requires the clinic to delete consultation exports after 6 years unless clinical record rules require longer. That gives both sides a clear path instead of relying on assumptions.

What Security, Retention And Breach Terms Should You Include?

You should include specific security, retention and breach terms that match the sensitivity of the data and the real risk to users.

For a health app, vague wording like reasonable security usually isn't enough on its own. Your agreement should turn security expectations into practical obligations that your technical and operations teams can actually follow.

Security Controls

Consider including requirements for:

• Encryption in transit and at rest
• Multi-factor authentication for admin accounts
• Role-based access controls
• Audit logs for access to health records
• Regular vulnerability testing and patching
• Secure development practices for APIs and integrations
• Staff confidentiality and training
• Pseudonymisation where direct identifiers aren't needed

If your app is processing health data at scale, or using new technology in a way that could create high risk, you'll often need a data protection impact assessment. The ICO expects businesses to use DPIAs for high-risk processing, and digital health projects commonly fall into that territory.

Retention And Deletion

Your agreement should say how long each party keeps the data and why that period is justified. Don't copy a retention period from another business unless it fits your use case.

For example, technical logs might be kept for 90 days, account data might be kept while the user has an account, and clinical records may need a longer period depending on who holds them and what health sector rules apply.

Breach Response

The UK GDPR requires a controller to report certain personal data breaches to the ICO without undue delay and, where feasible, within 72 hours of becoming aware of the breach. Your agreement should require suppliers to notify you much faster than that, so you have time to assess the risk.

Include a breach contact, evidence requirements, cooperation duties and a rule that no party contacts users or regulators about the other party's incident without an agreed process, unless the law requires it.

What About Labs, Clinics, AI Tools And Overseas Suppliers?

You need to check each partner's role, regulatory position and location before data is shared, because the contract terms may need to change.

A clinic may have its own professional and clinical record duties. A lab may need data to perform testing under its own systems. An AI supplier may want to use de-identified or pseudonymised data to improve its model. A cloud provider may store backups outside the UK.

Your agreement should deal with these differences rather than treating every partner like the same type of supplier.

Secondary Use Of Data

Be very careful with clauses that allow a partner to use data for product improvement, analytics, research or AI training. If the data can still identify someone, directly or indirectly, UK GDPR still applies. Pseudonymised data is still personal data if someone can re-identify the individual using additional information.

If you want to allow secondary use, define it tightly and consider whether a data licence agreement is also needed. Say exactly what data can be used, whether it's aggregated or anonymised, who can access it, and whether users have been told.

International Transfers

If personal data leaves the UK, your agreement should identify the transfer route. This might be a UK adequacy regulation, the UK International Data Transfer Agreement, or the UK Addendum to the EU Standard Contractual Clauses. Some US transfers may rely on the UK Extension to the EU-US Data Privacy Framework if the recipient is properly certified.

You may also need a transfer risk assessment, depending on the destination country and transfer mechanism.

Practical Partner Checks

Before signing, ask each partner for:

• A description of where data is hosted and accessed from
• Their information security summary or certification details
• A list of subprocessors involved in the service
• Their breach response process
• Their retention and deletion approach
• Confirmation of whether they use data for AI training, analytics or research

If their answers don't match the agreement, fix the agreement or the process before the integration goes live.

Key Takeaways

• A health app data sharing agreement should be tailored to the actual data flow, not copied from a generic supplier template.
• Get the controller, processor or joint controller roles right first, because the rest of the agreement depends on that split.
• Health data usually needs both an Article 6 lawful basis and an Article 9 special category condition under the UK GDPR.
• Your agreement should cover consent, user notices, security controls, retention, deletion, breach response and data subject rights.
• International transfers need a proper transfer mechanism, such as an adequacy regulation, IDTA or UK Addendum.
• Special care is needed where clinics, labs, AI suppliers or cloud providers want to use data for their own purposes.
