Tandem Cookie Notice Version 2026-09-05-draft.1
Draft for product-owner and UK specialist review. This revision does not authorise paid launch or replace a signed customer agreement.
Tandem uses authentication and session mechanisms to keep authorised users signed in and to enforce access controls. Local device storage may also hold interface preferences or queued worker actions. Storage needed for authentication and requested service functions must be distinguished from non-essential tracking.
Do not treat legal-notice acknowledgement as cookie consent. Non-essential analytics, advertising or session replay must have a separate assessment and any legally required consent before activation. Users must be able to manage any optional consent separately.
The final cookie and storage inventory must be verified against the deployed application, its actual providers, purposes and expiry periods. This draft does not certify that a deployment contains only essential technologies. Browser controls may clear stored data; workers should synchronise queued work before clearing application storage.
