Tamper-evident mobile & desktop data capture

Build records you can trust.

Carpe! turns a phone into a structured field-data system: local databases, BLE sensor ingestion, QR and barcode scanning, NFC tags, GPS capture, and record-level cryptographic integrity.

Designed for inspections, asset workflows, chain-of-custody records, research capture, and sensor-backed operations.

See Carpe! in action

Assets and scans

Data integrity proofs for real-world assets

NFC/RFID, QR codes, and barcodes captured directly into database records with proof material.

BLE ingestion

Tamper-evident data ingestion from BLE devices

Sensor payloads flow into records with decoding, mapping, and integrity tracking at insert time.

Any database

Record-level cryptographic integrity

Create local databases and generate cryptographic proofs for every record as it is written.

Data integrity infrastructure. Customizable.

Build local databases fast

Create databases, tables, and field types directly on the device so teams can start collecting structured data without a backend.

Capture from forms and sensors

Mix manual entry with QR codes, barcodes, NFC tags, GPS coordinates, attachments, and BLE sensor readings in the same workflow.

Automate BLE inserts

Configure BLE automations with polling or notifications, decoder mapping, and direct writes into your chosen table.

Keep data on-device

Carpe! is local-first. Records stay on the hardware unless the user explicitly exports or integrates them into another workflow.

Verify at record level

Each insert can produce cryptographic proof material so tables become tamper-evident over time instead of merely editable logs.

Demo and pilot quickly

Ideal for inspections, asset tracking, sensor logging, research capture, and operational teams exploring verifiable data collection.
