Privacy Policy

TwinFoundry Ltd ("we", "us", "our") operates the HomeEtch application ("the App"). This Privacy Policy explains how we collect, use, and protect your personal information when you use HomeEtch.

Information We Collect

When you use HomeEtch, we collect the following information:

• Account information — your name, email address, and organisation name when you register
• Property data — floor plans, room scans, component records, and notes you create within the app
• Usage data — app activity and diagnostic information to improve performance
• Device information — device type and iOS version for compatibility purposes

How We Use Your Information

We use the information we collect to:

• Provide, operate, and maintain the HomeEtch service
• Sync your property data securely across devices
• Send transactional emails — account verification, password reset, team invitations
• Diagnose technical issues and improve the app
• Comply with legal obligations

Data Storage and Security

Your data is stored securely on Amazon Web Services infrastructure located in the EU (eu-west-2, London region). We use industry-standard encryption for data in transit and at rest. Access to your data is strictly limited to authorised members of your organisation.

We do not sell, rent, or share your personal data with third parties for marketing purposes.

Team and Organisation Data

HomeEtch supports team accounts. When you invite a colleague to join your organisation, their email address is used solely to send an invitation and create their account. All members of an organisation can access that organisation's property records. Organisation owners can remove member access at any time.

Apple Sign In

If you register using Sign in with Apple, we receive only the information Apple provides — typically a name and email address. Apple may provide a private relay email address to protect your personal email. We store and use this address only for account management purposes.

Data Retention

We retain your data for as long as your account is active. You may request deletion of your account and all associated data at any time from within the app (Settings → Delete Account) or by contacting us at [email protected]. Deletion is permanent and cannot be undone.

Your Rights

Under UK GDPR, you have the right to:

• Access the personal data we hold about you
• Request correction of inaccurate data
• Request deletion of your data
• Object to processing of your data
• Data portability — receive your data in a machine-readable format

To exercise any of these rights, contact us at [email protected].

Cookies

HomeEtch is a native iOS application and does not use browser cookies. Our website (twinfoundry.co.uk) uses no tracking cookies or third-party analytics.

Children's Privacy

HomeEtch is a professional tool intended for use by adults. We do not knowingly collect personal information from anyone under the age of 18.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify registered users of any significant changes by email. Continued use of the app after changes constitutes acceptance of the updated policy.
