FAQ¶
- Does using a smart lock require ICO registration?
- For household use only - no. If you run a holiday let, Airbnb, or manage access for non-household members, you may need ICO registration (£35-£60 annual fee).
- How long should I keep activity logs?
- Household: 90 days recommended. HMO/rental: 12 months for fire safety compliance. Delete personal data when the user no longer requires access.
- Can someone request their data be deleted from my smart lock?
- Yes - under UK GDPR, users have the right to erasure. Delete their user profile and PIN code. For more information see our Smart Lock Integration with Alarm Systems.
