Terms of Use

Last updated: 13 August 2026

The service

ChallengeCalendars provides free challenge-tracking calendars and related tools. We aim for excellent uptime but the service is provided "as is", without warranties; export your data if it matters to you (your account page makes that one click).

Your account

• You're responsible for your password and anything done with your account.
• One person per account. You must be 13 or older.
• We may disable accounts used for abuse (spam content in shared calendars, attacks on the service, illegal content).

Your content

Challenge titles, descriptions and notes remain yours. By switching sharing on you make that calendar visible to anyone holding the link. Don't publish content that is illegal, hateful or someone else's private information.

Health disclaimer

Challenge descriptions on this site (including fitness and diet challenges) are general information, not medical advice. Consult a professional before starting any demanding physical or dietary program.

Changes

We may update these terms; material changes will be noted on this page. Continued use after changes means acceptance.
