The data we process

We process face scans, voice recordings, transcripts, your location, and your SIA licence details. Below, you can see where each type of data is stored and how we protect it.

Your data stays
in the UK

We work with a number of trusted partners to help operate OnSiren. Some store your data, while others support limited operational functions.

Amazon Web Services

Cloud hosting, AI inference (Bedrock), face-liveness detection (Rekognition), object storage (S3), and text-to-speech (Polly). London region (eu-west-2).

Anthropic

Claude foundation models for the Alpha-1 dispatcher. Accessed through AWS Bedrock (in eu-west-2) — prompts and completions stay inside AWS infrastructure and are not used to train Anthropic or Amazon models.

Deepgram

Speech-to-text, text-to-speech, and the Alpha-1 Voice Agent. Routed through Deepgram’s EU endpoint.

PostgreSQL

Primary relational database (Amazon RDS, eu-west-2). TLS in transit, certificate verification on.

Redis

In-memory cache, session store, and BullMQ job-queue backing. eu-west-2.

Self-hosted WebRTC transport for push-to-talk audio. UK or EU infrastructure.

Twilio

SMS one-time-password delivery. Phone number plus the message body (OTP codes today).

Google reCAPTCHA

Abuse and bot mitigation on phone OTP and the public claim flow.

Google Sign-In

Identity provider for the admin console. Staff only; officers never see it.

Slack

Optional operator notifications for the claim funnel. Off by default; phone numbers and emails are partial-masked.

Mailtrap

Transactional email delivery for system messages and OTP fallback. EU-incorporated (Czech Republic).

Google Tag Manager

Planned. Tag management container for analytics scripts on the landing site. Loads only after cookie consent.
