Know your child arrived safely, instantly

Presencia replaces the paper roll call with a reader at the school entrance. It recognizes each person on the device itself and alerts guardians through an app on their phone.

Join the waitlistHow it works
The problem

Taking attendance should not cost 20 minutes or leave doubts

Paper lists

They waste 10 to 20 minutes per session and are easy to forge.

Guardians left in the dark

Nobody confirms in real time that the child arrived safely.

Careless data handling

Personal and biometric data is handled informally.

How it works

Three pieces, one experience

  1. 01

    Reader at the entrance

    A camera device recognizes the person in under 2 seconds as they walk by. No queues, nothing to learn.

  2. 02

    On-device processing

    The face is turned into a numeric vector inside the reader itself. Images never leave the institution.

  3. 03

    Guardian alert

    The app notifies within seconds: “Ana arrived at 07:42”. With history, reports and late alerts.

The app

One app, two roles

For guardians

  • All your children in one list, even at different schools
  • Daily attendance with entry and exit times
  • Date-range reports and export
  • Share an event in anonymized form
  • Privacy centre: review, withdraw consent or request deletion of your data

For schools and businesses

  • Groups, rosters and adding people
  • Guardian invitations and acceptance status
  • Consent status for every person
  • Daily attendance summary and reader status
  • Reader setup from your phone (coming soon)
Privacy by design

Your trust is part of the product

We know this is about children’s faces. That is why we designed it this way from the start.

Images stay on the device

Only numeric vectors and event data are sent, never the face image.

Works offline

The reader stores events for up to 72 hours and syncs when the connection returns.

Never blocks entry

If recognition fails there is always a manual fallback, with the reason logged.

Consent and ARCO rights

Explicit consent, a privacy notice and flows for access, rectification, cancellation and opposition.

FAQ

What people usually ask

When will it be available?

We are building Presencia with a first pilot institution. People on the waitlist will be the first to know.

Are photos of my child stored?

Not by default. Recognition happens on the device and images are not sent to the cloud. Photo storage would be an optional add-on with separate consent.

What happens if recognition fails?

Entry is never blocked. Staff can confirm presence manually and it is logged.

What kind of institutions is it for?

We are starting with schools. The recognition engine is designed for other settings such as offices, gyms and gated communities.

Is the app free for guardians?

The commercial model is still being defined. We will let you know when we have it.
