Your employer could receive confirmation that you have activated a Calm subscription, which may indirectly reveal that you are seeking stress relief, mental health support, or sleep assistance.
Calm collects a broad range of personal data including mood check-ins, sleep habits, health app data, and inferred characteristics like age and gender, which may be shared with advertising partners and used for behavioral targeting across the web. Some of this data sharing may qualify as a 'sale' of personal data under CCPA and similar laws. You can opt out of targeted advertising and data sharing by visiting calm.com/optout or using the Cookie Preferences Manager on the Calm website.
