Security & trust

your data. your code. your software.

Custom software means letting someone inside your business. Here's exactly how we treat that access: what we take, what we don't, and what you keep. No legalese, no fine print.

The controls

Data handling

where your data lives

UK South

Azure UK South by default, EU on request. US only where you require it.

what we keep afterwards

Nothing

Working copies are deleted at the end of the engagement. You do not have to ask.

backups

Encrypted, restores tested

Backups do not cross a border the data itself has not: a UK deployment's backups stay in the UK.

who can reach it

MFA on every system

Multi-factor authentication on every system that touches client code, on scoped accounts revoked the day we finish.

Sub-processors and AI

vendor purpose region
Microsoft Azure hosting and infrastructure UK South
GitHub source control and CI United States
Anthropic model access for our build tooling United States
OpenAI model access for our build tooling United States
changes to this list

30 days' notice

UK GDPR Art. 28(2): you are told before a sub-processor is added or replaced, and you can object.

AI and your code

Never used for training

Client code reaches a model only through build tooling we wrote and run ourselves, against vendor APIs whose terms prohibit training on what is sent — never a consumer chat product. Inputs may be held up to 30 days for the vendor's abuse monitoring; we hold no zero-retention agreement. Credentials, personal data and production databases never go near a model.

Incident response

critical

12 hours

Confirmed incident involving your data.

high

24 hours

Suspected incident, no confirmed exposure.

low

72 hours

Security-relevant event with no client impact.

The architecture diagram is drawn for your engagement rather than pulled off a shelf — you get the one that describes your system, not a generic picture.

The commitments
01 · Data & privacy

We see the minimum. You keep everything.

An audit needs visibility, not custody. We work against the smallest slice of data that answers the question, anonymised or synthetic where possible.

  • Least-access by default: scoped accounts, revocable the day we're done
  • GDPR-aligned handling; EU data stays in the EU when you need it to
  • Your data is never used to train anything, sold, or shared
  • Working copies deleted at the end of every engagement, without you asking
02 · IP & ownership

You own the code. All of it.

The software we build for you is yours: source, infrastructure config, documentation, the lot. We don't rent you your own product.

  • Full IP assignment on delivery, in plain contract language
  • Standard, boring stacks: any competent team can take over
  • Code escrow available for the cautious
  • No lock-in: leaving us costs you a handshake, not a migration
03 · Confidentiality

NDA first. Names never.

Most engagements start with an NDA before we see anything, ours or yours, whichever's stricter. What we learn inside your business stays there.

  • NDA by default before any audit begins
  • Named access list: you know exactly who can see what
  • No case studies, logos, or numbers published without written consent
04 · Secure development

Boring, disciplined, auditable.

Security isn't a feature we add at the end. It's how the work happens, from the first commit.

  • Secrets live in managed vaults, never in code, chat, or email
  • Least-privilege access for every environment, reviewed monthly
  • Dependencies audited and pinned; updates are deliberate, not drive-by
  • Every change reviewed before merge; every release versioned and reversible
05 · Hosting & compliance

Compliance-ready from day one.

We deploy on infrastructure your auditors already trust, configured so a future SOC 2 or ISO journey starts from "mostly done" rather than zero.

  • SOC 2-ready cloud providers; UK South by default, EU on request, US only where you require it
  • Encryption in transit and at rest, everywhere, no exceptions
  • Automated backups with recovery we test, not assume
  • Audit logs your compliance team can read without calling us
06 · What we don't do

The quiet part, out loud.

Some of the industry's defaults aren't ours. For the avoidance of any doubt:

  • No analytics, trackers, or phone-home code hidden in your product
  • No reselling, benchmarking, or "anonymised insights" from your data
  • No shadow subcontracting: the people you meet do the work
  • No hostage tactics: access, docs, and keys are handed over as we go
