About this DPIA
This DPIA assesses the data-protection risks of Hubb's Messaging (adult-to-adult) and Safe Messaging (leader-to-child) features. A DPIA is mandatory here because the processing combines several high-risk markers: children's data, special-category (religious) data, and ongoing review of messages. It is a working assessment to brief the relying churches; it is not legal advice and not a sign-off.
Owner: Adam Johannes (CEO), who is Hubb's data-protection lead and its named accountable individual for online safety. Reviewed with: church DPOs as controllers. Review cycle: at least annually and on any material change to the feature.
1. Description of the processing
What the feature does. Authorised church leaders send short, text-only pastoral messages to a child through the church's own Hubb app. Messages are one-way by default — children cannot reply through the tool. Each message is routed to the child's parent or guardian, who must approve it before delivery; an unapproved message expires. An appointed church Safeguarding Lead has standing visibility of messages across all leaders and children in their church. The adult Messaging feature provides one-to-one and group messaging for teams and ministries.
Personal data processed. Names and contact records of leaders, parents and children; family/guardian relationships; the message content; and an audit record of who sent each message, what was said, when, and which parent approved or rejected it (with any rejection note). Children's date of birth is held on the platform, entered by a guardian or church administrator — never by the child.
Special-category data. Participation in a church app and the content of faith-based messages will in many cases reveal a child's religious belief, which is special-category data under Article 9. See the accompanying Appropriate Policy Document.
Children's access. Own-login access for children is controlled by site administrators (controllers). Under-13 self-login is off by default and can be enabled only by a deliberate site-admin choice, with that church taking responsibility for the additional safeguards required — including verified parental consent for an online service offered to a child. By default, under-13s have no login of their own and a parent views the child's messages through the parent's own account. Whether 13–17s have their own login is a site-admin configuration choice. Either way, the service is by design likely to be accessed by children, so the Children's Code and the Online Safety Act child-safety duties apply (assessed separately in the OSA pack).
Hosting. Data is hosted in the UK with no international transfer. Chat is text-only (no image or video), which removes the image-upload vector for child sexual abuse material from this feature.
2. Roles and responsibilities
-
Churches are controllers of their members', leaders' and children's data; each church has a named DPO.
-
Hubb is the processor providing the platform, acting on documented controller instructions under Article 28 contract terms.
-
Hubb is also the "provider" for Online Safety Act purposes — those duties, and the Children's Code design duties, fall on Hubb directly regardless of the processor classification.
-
Each church appoints a Safeguarding Lead (assignable in Hubb) who exercises the standing oversight described above.
3. Necessity and proportionality
Purpose. To let vetted leaders give purposeful pastoral encouragement to young people during the week, under parental approval and independent safeguarding oversight, using an official church channel rather than personal accounts or phone numbers.
Lawful basis (to be confirmed by each controller). For the church's own members, the not-for-profit religious-aim condition (Article 9(2)(d)) is the natural route for religious-belief data; the safeguarding activity engages the "safeguarding of children" substantial-public-interest condition (DPA 2018 Schedule 1, paragraph 18), which requires an Appropriate Policy Document. The ordinary lawful basis is likely legitimate interests or consent depending on the controller's configuration.
Data minimisation. Messages are short and purposeful; no images or video; no profiling; no use of children's data for marketing. The Safeguarding Lead's standing access is the most significant minimisation question: it is justified because a single parent cannot detect grooming patterns that only become visible across multiple leaders and children, and because the codes expect a second, trained church adult to have sight of individual contact. That access must be active and recorded, limited to appointed leads, and not extended to anyone without a safeguarding role.
Children's privacy trade-off. A parent plus a Safeguarding Lead reading messages reduces an older child's own privacy. This is proportionate for a one-way, purposeful pastoral channel.
4. Risks and mitigations
|
Risk |
Mitigation built in |
Residual action |
|
Grooming via individually-innocuous messages that a parent cannot detect |
One-way design; Safeguarding Lead has cross-cutting visibility of all leaders/children to spot patterns; vetted/DBS leaders only; audit log |
Oversight must be active not nominal; set review expectations for the Safeguarding Lead |
|
Safeguarding Lead over-access to children's data |
Access limited to appointed lead(s); justified and recorded here under data minimisation; no wider staff access |
Record who holds the role; review annually |
|
Under-13 consent / verifying parental responsibility |
Under-13 self-login off by default; parent-mediated via the parent's own account; family units set by church admin or parent at registration |
Where a controller enables under-13 self-login it must obtain and verify parental consent and add the extra safeguards; confirm parental responsibility |
|
Special-category (religious) data exposure |
UK-only hosting; access controls; Appropriate Policy Document for the safeguarding condition |
Each controller to confirm its Article 9 condition |
|
Retention / erasure of a child's records |
All messages stored and auditable |
Implement deletion on leaving and a data-subject-rights route (see Retention procedure) |
|
Message approved by wrong adult / mis-set family unit |
Parent-approval step; rejection-with-note actively reviewed by the church |
Church to verify guardian links at registration |
|
Illegal content / disclosure of harm |
Text-only (no image upload); rejection-with-note review; church safeguarding procedures apply |
Platform reporting route available (see OSA pack); includes escalation to statutory agencies |
6. Children's Code — standards most engaged
Best interests of the child as a primary consideration; DPIA completed (this document); age-appropriate settings; data minimisation; high privacy by default; transparency in age-appropriate language; profiling off; no nudge techniques; and care over data sharing — which directly covers the Safeguarding Lead's access, addressed in section 3. Birthday messages are a flagship use: these are pastoral, not promotional, and must not be used to push offers or marketing.
7. DUAA — children's higher protection matters
Recorded as a design input (in force 5 February 2026): how the feature protects and supports children; that children may not appreciate data risks; and that children have different needs at different ages — reflected in the parent-mediated under-13 model and the option of tighter defaults for primary-age children.
8. Outcome and sign-off
Residual risk: assessed as low-to-medium for a tightly controlled, one-way, text-only service, conditional on the residual actions above being completed and a qualified legal review before scaling. Approved by: Adam Johannes (CEO) — date [1-June-2026]. Controller adoption: each church to record adoption via its DPO.
