PostHog (EU)
We use PostHog (EU region) to collect anonymous usage counts for our public landing page — for example, how many visitors start the interactive demo, reach the invoice stage, or click a sign-up call-to-action. No cookies or similar storage are set on your device, no visitor-entered demo content is transmitted, and no user identification is performed. Each pageload generates a fresh in-memory identifier that is not persisted or linked to any other visit or to your account. See: posthog.com/privacy
Other users in your workspace
If you are invited to a workspace, the workspace Owner can see your name and the jobs you are assigned to.
Legal requirements
We may disclose your data where required by law, court order, or to protect the rights and safety of others.
We do not sell your personal data to any third party.
Some third-party processors may process data outside the UK or EEA. Where this occurs, we ensure appropriate safeguards are in place, such as the UK International Data Transfer Agreement (IDTA) or equivalent standard contractual clauses.
We retain your data for as long as your account is active. If you close your account, we will delete or anonymise your personal data within 90 days, except where we are required to retain it for legal, tax, or accounting purposes (typically up to 7 years for financial records).
Under UK GDPR, you have the right to:
To exercise any of these rights, email support@crewsynk.co.uk. We will respond within 30 days.

We take reasonable technical and organisational measures to protect your data, including encrypted data storage, secure HTTPS connections, and access controls. No system is completely secure and we cannot guarantee absolute security.
We implement access controls and technical safeguards to ensure that users can only access data relevant to their own account or workspace.
CrewSynk is not intended for use by anyone under 18. We do not knowingly collect data from children. If you believe a child has provided us with personal data, please contact us and we will delete it.
