Samipyo

Student safety platform for schools

Where is this student, and can that be confirmed?

Samipyo brings manual confirmation and bus GPS into one record, with automatic detection planned. Every event keeps its source, so a school or a parent can see what is known, how it is known and how confident it is, and what is not.

Student A Confirmed by staff
  1. Boarded the bus Manual
  2. Arrived at school Manual
  3. No evidence for the afternoon trip yet Unknown This is not the same as absent.

Planned: automatic detection

Evidence becomes a state

A state is only as strong as the evidence behind it

Each source adds evidence. A fixed set of rules turns that evidence into a state, and when there is none, the state stays unknown. Staff see the evidence and source according to their role; parents see the state, its confidence and a source-tagged timeline.

From evidence to state Three evidence sources feed one evidence record. Manual confirmation by a named staff member and bus GPS during an active trip are built so far. Bluetooth detection is planned and not built yet. The evidence is kept as recorded, with its source, and is never overwritten. A deterministic, auditable state engine turns it into a state. There are three outputs. Confirmed: confirmed by staff, with its source. Derived: from a weaker signal such as bus GPS, shown as less certain. Unknown: no evidence is never read as absent. Manual confirmation A named staff member confirms boarding or exit Bus GPS Bus position during an active trip BLE detection Planned Planned, not built yet Evidence Kept as recorded, with its source, never overwritten State engine Same evidence in, same state out.

Evidence from staff and the bus is kept as recorded and turned into a state by fixed rules. A state confirmed by staff is distinguished from one derived from a weaker signal, and where there is no evidence the state stays unknown.

Every event keeps its source

Staff confirmations and bus GPS stay labelled, so "did someone confirm it, or did the bus report it?" has an answer.

No evidence is not absence

A student with no confirmation or GPS-based evidence is shown as unknown, never stated as not there.

A person can correct it

Authorised staff can correct a state, and the correction records who, when and why.

No evidence is not absence.

When nothing has been recorded for a student, Samipyo says it does not know. It does not turn silence into a claim that the student is not there.

Honest about where we are

What is built so far

Built so far

  • Manual boarding, exit and correction by authorised staff
  • Bus GPS during an active transport session
  • School arrival and departure sessions
  • Exceptions raised and resolved with a record

Planned

  • Automatic detection with Bluetooth tags on ordinary staff phones

Samipyo reports evidence and what can be derived from it. It does not promise that a child is safe, and it does not track children outside an active school or transport session.

Built for the question schools are asked every day

Where is this student, and can that be confirmed? Samipyo keeps the answer, and the evidence for it, in one record.
