4. Who We Share Data With

We share data only where necessary:

Supabase

Our database and authentication provider. Your data is stored on Supabase infrastructure. Supabase acts as a data processor on our behalf.

Our payment processor. When you subscribe, your payment information is handled directly by Stripe. We receive confirmation of payment status only. See: stripe.com/gb/privacy

Resend

Our email delivery service used for invoice emails and notifications. Email content and recipient addresses are transmitted to Resend for delivery. See: resend.com/legal/privacy-policy

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.

5. International Transfers

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.

6. Data Retention

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).

7. Your Rights

Under UK GDPR, you have the right to:

  • Access — request a copy of the personal data we hold about you
  • Rectification — ask us to correct inaccurate data
  • Erasure — ask us to delete your data, subject to legal retention obligations
  • Restriction — ask us to limit how we use your data
  • Portability — receive your data in a machine-readable format
  • Object — object to processing based on legitimate interests

To exercise any of these rights, email support@crewsynk.co.uk. We will respond within 30 days.

You also have the right to lodge a complaint with the Information Commissioner's Office (ICO) at ico.org.uk or by calling 0303 123 1113.

8. Security

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.

9. Children

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.
