Cookie policy
Last updated: 3 June 2026
This policy describes how InsideData Ltd, trading as Tandem, uses cookies and similar technologies on our website and application.
What are cookies?
Cookies are small text files stored on your device when you visit a site. They help the site work, remember preferences, and understand how the service is used.
How we use cookies
Strictly necessary
These cookies are required for the service to function. They cannot be switched off in our systems. They are usually set in response to actions you take, such as logging in or completing security checks.
| Purpose | Examples |
|---|---|
| Authentication and session management | Keeping you signed in to the supplier workspace or partner portal |
| Security | Protecting forms and preventing abuse |
| Site access | Remembering access when a site-wide preview password is enabled |
Functional
These cookies enable enhanced functionality, such as remembering choices you make. If you disable them, some features may not work as expected.
Analytics and performance
Where we use analytics tools, these cookies help us understand how visitors use our marketing pages so we can improve them. We configure analytics to minimise personal data where possible.
Third-party cookies
Some cookies may be set by trusted third parties that provide services on our behalf, for example:
- Payment processing — when you manage billing, our payment provider may set cookies required for checkout and fraud prevention.
- Embedded content — if we embed external documentation or tools, those providers may set their own cookies subject to their policies.
Managing cookies
You can control cookies through your browser settings (block, delete, or alert). Blocking strictly necessary cookies may prevent you from using parts of Tandem.
For more about how we handle personal data, see our privacy policy.
