Only what we
need.

Codex ISO uses information required to operate the store, fulfil purchases, secure downloads and understand how the archive is used. Payment card details are handled by Stripe rather than stored by Codex ISO. Purchase records may include your email address, order identifier and the editions purchased so that access can be fulfilled or restored.

We also record first-party, anonymous usage information such as pages viewed, on-site searches, referral and campaign details, approximate location supplied by our hosting provider, device category and purchase-funnel events. Anonymous visitor and session identifiers are stored in your browser. We do not store IP addresses in the analytics event stream.
