Data Mapping · the Article 30 feeder

Privacy data mapping software that gives your records one living map to stand on

See every system, vendor, recipient, purpose, transfer and retention period in one place — and let the map feed your RoPA, DPIAs and risk reviews instead of living beside them.

A working privacy inventory, not another diagram — grounded in the records your assessments and Article 30 register already use.

Data flow mapping

Data flow mapping across systems and vendors

Data rarely sits in one place. Acompli helps privacy teams map the flow from collection to system, vendor, recipient, retention and deletion, with links back to the governance decisions and source evidence behind every published relationship.

StartPopulate the map

Bring in systems, suppliers, and processing activity

Record systems, vendors, locations, and processing activities as part of normal assessment and governance work — or import them from existing registers.

Acompli supports structured intake of supplier and system information so organisations can build connected records within a governed structure. AI-assisted mapping helps interpret current layouts and propose likely matches.

Map inputs. Reviewable outputs.

Systems

Applications, repositories and storage locations that hold or process personal data.

Vendors

Processors, recipients and suppliers linked to the flows they touch.

Locations & Transfers

Geographic context linked to systems and suppliers for transfer visibility.

Data Categories

Personal-data and data-subject categories tied to each processing activity.

Retention

Retention periods and deletion expectations kept with the mapped flow.

Source Evidence

Assessments, imports and reviewed records that explain why the node exists.

Always tied to the register Every map node can trace back to a RoPA activity, source record or reviewed assessment.

How the map is built

The data map is generated from records, not redrawn by hand

This explains where the map comes from: IT systems, vendors, locations and RoPA activities become graph objects with source IDs. AI can polish layout, but it cannot invent unsupported nodes.

Map to governance

One data flow can trigger several compliance records

A data map is useful when signals become work: third-country transfers, AI systems, processors handling special-category data and missing retention evidence route into the right follow-up.

Where the diagram comes from

Your records own the map — AI polishes presentation only.

Data Mapping doesn't ask you to redraw your estate in a diagramming tool. The map is derived from records you already maintain: third parties, IT systems, and processing locations in the shared knowledge base, plus RoPA processing activities approved through assessments. Flows link to the RoPA activity IDs that produced them; nodes carry provenance back to source records.

A rule-based engine owns the map's structure — what is on it, how it connects, and which boundaries cross borders. AI may only improve presentation from that snapshot; it cannot invent, remove, or rename nodes. Diagrams stay honest because the source of truth is the register, not a model output.

Key takeaways

  • There is no standalone “data map” law — but Article 30 of the GDPR (Ireland, via the DPC) and the UK GDPR (ICO) require accurate, current records of processing, and a living data map is how those records stay accurate.
  • Cross-border flows are the audit pressure point — every transfer out of the EEA needs its destination and mechanism (SCCs, adequacy, or a derogation) shown and linked to a Transfer Impact Assessment after Schrems II (C-311/18).
  • When comparing data-mapping tools, favour one where the map is derived from your Article 30 register over a separate diagram maintained by hand.
  • A map should feed the RoPA, not duplicate it — each flow references the processing-activity ID that produced it, so one update keeps both current.

Data inventory answer

What is privacy data mapping software?

Privacy data mapping software keeps the inventory behind your Article 30 register alive. It records systems, vendors, data categories, data subjects, purposes, recipients, retention periods, transfers and safeguards in one connected map, so privacy teams can answer GDPR accountability questions from reviewed evidence rather than a stale diagram.

Acompli builds that map from the records your programme already maintains: processing activities, systems, vendors, locations, assessments and transfer context. The data map becomes a feeder for RoPA, DPIAs and third-party risk rather than a parallel file somebody has to reconcile by hand.

The questions your data map should answer

  1. What personal data do we process?
  2. Which systems hold or process it?
  3. Which vendors or processors have access?
  4. Why do we process it?
  5. Which RoPA records, DPIAs and risks depend on it?

Flows that stay tied to source records

Acompli helps privacy teams map the flow from collection to system, vendor, recipient, retention and deletion so third-party access, transfer risk, DPIA triggers and records that need review are easier to see.

What should GDPR data mapping software track?

GDPR data mapping software should track the fields that keep an Article 30 RoPA accurate: the activity, purpose, data subjects, personal-data categories, recipients, transfers, retention, safeguards, systems and the source evidence behind each flow. The GDPR does not name a data map as a separate statutory artefact, but the map is the evidence layer that keeps Article 30 records current and makes data-flow mapping useful to the DPC or ICO.

Which tool

Which type of data mapping software fits you?

“Data mapping” means very different things. Moving data between systems (ETL) and cataloguing a warehouse are different jobs from mapping personal data for GDPR Article 30 — the right tool depends on which one you actually need.

Data mapping FAQ

Frequently Asked Questions

What is privacy data mapping software?

Privacy data mapping software inventories personal data and maps how it moves across systems, vendors, recipients, purposes, retention and transfers. In Acompli the map is built from reviewed records rather than a one-off workshop: systems, suppliers and processing context stay connected, so the map updates as the business changes instead of expiring in a diagram.

What is GDPR data mapping software?

GDPR data mapping software keeps the accountability evidence behind your Article 30 register: which systems hold personal data, which vendors receive it, why it is processed, how long it is kept and where it crosses borders. Acompli feeds those facts straight into RoPA records and assessments without re-keying, with transfers flagged for Schrems II safeguards.

How does data mapping support Article 30 RoPA?

Each Article 30 record needs purposes, categories, recipients, transfers and retention - exactly what the data map holds. In Acompli the map is the feeder: processing activities link to the mapped systems and vendors behind them, so when the map changes, the affected register entries surface for review instead of silently going stale.

How does data mapping support DPIAs?

A DPIA starts with an accurate description of the processing - what data, which systems, which vendors, where it flows. Acompli pulls that description from the live map, so assessments begin from reviewed facts; and where a flow crosses borders, the transfer is flagged for Schrems II analysis inside the assessment.

Is a data map the same as a RoPA?

No. The data map is the evidence layer - systems, flows and inventory; the RoPA is the legal register of processing activities under Article 30 that the DPC and ICO inspect. In Acompli they stay linked: the map feeds the register, and each register entry can show the mapped systems and vendors behind it.

What makes a data map useful for Article 30 readiness?

The map should feed the Article 30 RoPA without re-keying, stay current as systems and vendors change, and make cross-border flows explicit. In Acompli the map is derived from reviewed records in the shared knowledge base, so it is not a parallel diagram that has to be maintained by hand.

Is keeping a current data map a legal requirement in Ireland and the UK?

There is no standalone 'data map' article, but Article 30 GDPR — applied in Ireland (enforced by the Data Protection Commission) and mirrored in the UK GDPR / Data Protection Act 2018 (enforced by the ICO) — requires controllers and processors to maintain accurate records of processing, and a data map is how those records stay accurate. A stale map yields a stale Article 30 record. Acompli derives the map from the same register that produces your RoPA, so the two cannot diverge.

What should data-mapping software track for Schrems II international transfers?

It should surface every flow that leaves the EEA, the destination country, and the transfer mechanism (Standard Contractual Clauses, an adequacy decision, or a derogation), and link each to the Article 30 record and its Transfer Impact Assessment. Acompli groups recipients in third countries into explicit trust boundaries on the diagram, supporting GDPR Chapter V transfer governance with a regulator-ready visual. This operationalises the CJEU's Schrems II ruling (Case C-311/18), and it matters in Ireland in particular, where the DPC is lead supervisory authority for many large US-headquartered processors.

How does a data map stay current instead of going stale after the audit?

Because the map is derived from the records that already govern your estate — knowledge-base entities plus approved RoPA activities — so updates happen as part of normal review rather than a separate clean-up exercise. A deterministic engine owns the topology (what is on the map and how it connects); AI may only improve presentation and cannot invent, remove or rename nodes, so the diagram stays tied to the register.

Does data mapping replace your RoPA or DPIAs?

No — mapping, the Article 30 RoPA, and DPIAs serve different purposes, and Acompli keeps them connected so you can move from a flow on the map to the right record, assessment or risk entry without re-keying. Each flow references the RoPA activity ID that produced it, and nodes carry provenance back to source records.

How can data mapping flag AI systems for EU AI Act Annex III review?

Mapping where personal data flows into AI and automated-decision systems lets a team check those systems against the EU AI Act's Annex III high-risk categories. When Acompli's Code Scan surfaces AI usage in a connected repository and a DPO confirms the findings, the confirmed entries are written into the data map alongside the records-driven nodes, so the AI footprint is visible. Classification against Annex III is a human decision; Code Scan produces reviewable signals, not determinations.

Can we import an existing data map or inventory?

Yes. Existing system, vendor and location records can be imported into the shared knowledge base, and the map is generated from them — so you do not start from a blank diagram. Imported items remain reviewable, and the platform keeps enriching them as new assessments and records are approved.

What is the best data mapping software?

The best data mapping software is decided less by how the diagram looks than by whether the map is derived from your Article 30 records rather than redrawn by hand, whether each flow shows its cross-border transfer mechanism, and whether every node traces back to a source record a DPC or ICO inspection can follow. Acompli's angle is to govern these as connected, human-approved records tied to the wider GDPR and EU AI Act programme, each traceable to approved evidence rather than a standalone diagram. For a balanced, unbiased comparison of the available suppliers - evidence-based, drawn from public sources, and honest about where competitors are stronger than Acompli - we have compiled capability charts and vendor-by-vendor breakdowns for you to consider in our full comparison library.
