Winter Arc stores only what it needs to run your 30-day challenge: your name, your start date, your daily goals, the habits you create and the days you save.
Your data is tied to your account and is only readable by you. We do not sell your data and we do not share your daily entries with creators or advertisers.
If you arrive through a creator link, we store the creator's handle so they can see how many people started a challenge — never your personal entries.
Resetting your challenge permanently deletes its days, streak and badges. To delete your account entirely, contact us.
