Cairn — Privacy Policy

Last updated: June 2026

What Cairn collects

Cairn assigns each user an anonymous identifier when you first open the app. This identifier has no connection to your name, email address, phone number, or any personal information.

The following data is stored on Supabase (our database provider):

• Your chosen circle colour and identity mark
• Your daily goal type (e.g. fitness, creative, work)
• Whether you completed your goal each day

What Cairn never collects

• Your name, email, or any contact information
• Your intention text — this stays on your device only, never uploaded
• Your location
• Any information that could identify you to other users

How your data is used

Your anonymous data is used only to show your circle whether you have completed your goal today. No personal data is sold, shared, or used for advertising.
