UK GDPR and PECR
This is general information, not legal advice. Your legal adviser has the final word.
UK GDPR and the Data Protection Act 2018
The UK GDPR and the Data Protection Act 2018 set the rules for personal data in the UK, supervised by the Information Commissioner's Office (ICO). We plan consent, data minimisation and deletion into the app from the first sprint.
Official source: Data Protection Act 2018 (legislation.gov.uk) ↗PECR: storing data on devices
Regulation 6 of PECR limits storing or reading information on a user's device, for example for tracking, unless an exception applies. The rule was rewritten by the Data (Use and Access) Act 2025 from 5 February 2026. We build consent into the app itself.

Should we build a native app or use Flutter or React Native?

How do we work together if you are not in Birmingham?
With a kick-off workshop, a demo after every two-week sprint and weekly check-ins, led from our London office in the same time zone. Meet us in person at our London office or at any of our 10 offices, or by video.
Do you build apps for manufacturers?
Yes, for example field service, ordering, maintenance and internal apps that connect to your existing systems through their APIs and work on the shop floor or on the road.
