Privacy Policy

Last updated: June 13, 2026

This privacy policy explains what data we collect, why we collect it, how we use it, and your rights. We've written it in plain English.

When we say "we", "us" or "our", we mean Book Time Off, operated by BDI Resourcing Ltd.

Legal basis for processing personal data

We collect and process personal data to provide you with Book Time Off, in line with our Terms of Service. We also process data for our legitimate business interests: running the service, billing, security, and improving the product.

What personal data do we collect?

How do we use your data?

When you sign up

We collect your name, email, and company name to create your account. We verify your email address using a one-time code. We use your email to send password resets and essential account notifications.

When you pay

Payment is handled entirely by Stripe. Your card details go directly to Stripe's servers and never pass through ours.

When you use Book Time Off

Your team's leave data is stored so the application can function. We send email notifications for leave requests and approvals via Resend.

When you connect Microsoft 365

Microsoft 365 features are optional and stay off until you turn them on. If you sign in with Microsoft, we receive your name, email address and a Microsoft account identifier so we can authenticate you. If you connect Outlook calendar sync, we create, update and remove calendar events for approved leave on the calendars you authorise. If your organisation installs the Book Time Off app for Microsoft Teams, we process the work email and Microsoft account identifier of the people who use it, so we can match them to their Book Time Off account, and we post leave notifications and the daily who's-off summary to the channel you choose. We never read your mailbox, your files or your chat history, and a leave type you mark as private never shows its reason in a Teams post. You can disconnect any of these at any time in Settings, which stops the processing.

When you connect Slack

Slack features are optional and stay off until an admin turns them on. If you sign in with Slack, we receive your name, email address and a Slack account identifier so we can authenticate you. If your organisation connects its Slack workspace, we process the work email and Slack account identifier of the people who use the app, so we can match them to their Book Time Off account, and we send leave request and approval messages, post the daily who's-off summary to the channel you choose, and answer the /whosoff command. If you connect your own Slack, we set your Slack status to show when you are on approved leave, and clear it when you return. We never read your Slack conversations. You can disconnect the workspace or your own account at any time in Settings, which stops the processing and removes the stored access tokens.

When you contact support

If you email us, we use your name and email address to respond. We keep support conversations for up to 12 months.
