Privacy at Croft

What Croft collects, who can see it, and what it never records.

Our privacy promise

We never sell your data. Your trust is more valuable than any sale.

Your information, your family's information, and the data from your home monitoring system belongs to you. We never sell it or rent it, and your home monitoring data is never shared with marketers or data brokers. The only data we share for advertising is limited website usage data, sent to Meta so our adverts reach the families who would genuinely benefit from a system like this.

We only use your information to:

  • Provide the service you've signed up for
  • Alert the people in their circle through the Croft app if a fall is detected, until someone acknowledges it
  • Improve our systems to better serve your family
  • Communicate with you about your service and account
  • Make sure our advertising reaches the people who are most likely to find Croft useful

What data we collect

Account information

When you sign up, we collect:

  • Your name and contact information
  • Your parent's name and address
  • Contact details for the people in their trusted circle
  • If you join the pilot, payment details will be handled by our payment processor and never stored by Croft.

Home sensor data

Croft's radar fall sensors and hub collect:

  • Presence and movement in each room, measured by radar (no images or sound)
  • Fall events, and when and by whom an alert was acknowledged
  • Hub and sensor status, including signal and mobile data connection

What we do not collect

Privacy protected:

  • Video or audio recordings
  • GPS location tracking
  • Biometric data
  • Medical information

How we protect data

Encryption

Data is encrypted between the hub, our servers and the Croft app, and encrypted again when stored.

Where data is stored

Our website runs on Cloudflare. Hosting home data in the UK is planned; we will confirm where data is stored before the pilot starts.

Limited access

Only essential Croft staff can access your data, and only when necessary to provide support or resolve issues. All access is logged and audited.

Secure login

Croft app access requires strong passwords when accessing from outside the home to keep your account protected and private.

Who can see the data

You control who sees what.

Your parent:
Can see their home's status and decide who is in their circle.
Their circle:
You choose who gets alerts and access to the Croft app. Each person must be explicitly invited and can be removed at any time.
Croft support team:
Can access data only when troubleshooting issues or providing support, with your permission. All access is logged.
Third parties:
We never sell your data, and your home monitoring data is never shared with anyone. We share limited website usage data with Meta purely so our adverts are shown to people who are likely to be interested in a system like this. Names, addresses and anything from inside the home are never included.
