The short version

  • Each has a real cost: Clue clues stated policy on not sharing data with law enforcement without a valid legal process is the companys own published position and legal interpretation, not an independent guarantee, and it can still be compelled to comply with a legally binding request under EU or other applicable law.; DHIS2 the licence is free and the implementation is not; national rollouts routinely cost hundreds of thousands of dollars in configuration, hosting, training and support, and budgets built on the word free fail immediately.
  • They diverge on capability: Clue covers Cycle and symptom tracking, DHIS2 covers Aggregate data reporting.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Clue

  • Clues stated policy on not sharing data with law enforcement without a valid legal process is the companys own published position and legal interpretation, not an independent guarantee, and it can still be compelled to comply with a legally binding request under EU or other applicable law.
  • Deeper cycle insights and predictions, the features most likely to justify tracking in the first place, are gated behind the Clue Plus subscription rather than fully free.
  • Being a smaller company than some competitors, Clue has less capital and legal resource to contest large-scale legal requests than a larger, better-funded rival might, despite its stated intent to do so.
  • Research partnerships using anonymised user data, while opt-in, still mean user-derived data can be used in ways beyond direct app functionality, and users should check current consent settings.
  • Cycle predictions rely on self-reported data and general population models, so accuracy for irregular cycles or specific medical conditions remains limited regardless of which app is used.

DHIS2

  • The licence is free and the implementation is not; national rollouts routinely cost hundreds of thousands of dollars in configuration, hosting, training and support, and budgets built on the word free fail immediately.
  • HISP UiO introduced a Shared Services Fee in 2025, so organisations that depend on DHIS2 are now being asked for an annual contribution that did not previously exist in their plans.
  • Development funding comes from a small set of donors including Norad, the Global Fund and the Gates Foundation, which concentrates the platform's long-term direction in the priorities of those funders.
  • Implementation capability is concentrated in regional HISP groups, so a country whose local HISP group is overstretched has few alternative suppliers with equivalent expertise.
  • Analytics performance depends heavily on how metadata was designed at the outset, and a poorly structured initial configuration produces slow dashboards and bad indicator definitions that are painful to correct years later.

Answered from the vendors’ own pages

Clue: Does Clue share data with law enforcement?

DHIS2: Who owns and develops DHIS2?

The HISP Centre at the University of Oslo, funded by donors including Norad, the Global Fund, the Gates Foundation and Wellcome.

Clue: Why does Clue emphasise being an EU company?

Clue operates under EU GDPR data protection rules and states this legal basis makes it harder for authorities outside the EU, including US authorities, to compel data disclosure than for a company based in the US.

DHIS2: Is DHIS2 free?

The software is free under a BSD licence. Implementation, hosting, training and support are not, and are the dominant cost.

Clue: Is Clue free?
