Terms of Service

These terms are the agreement between you and CRESCO ("we", "us") for use of the Day One app and website ("the service"). By using Day One, you agree to them. If you don't agree, please don't use the service.

1. Using Day One

• You may use Day One for your own personal, non-commercial fitness.
• You must be at least 13 years old (or the minimum digital age in your country).
• Don't misuse the service: no reverse-engineering, reselling, or using it to harm others or break the law.

2. It's free, and it has ads

Day One is free to use. We keep it free by showing ads (through Google AdMob). By using the app you agree to see ads, which are handled per our Privacy Policy and Google's terms. We may add optional paid features in the future; anything paid will be clearly marked.

3. Not medical advice

Day One provides general fitness and wellness information only. It is not medical advice and is not a substitute for a doctor, physiotherapist, or dietitian. Exercise has inherent risks. You use Day One at your own risk, and you're responsible for exercising safely and within your limits. Check with a healthcare professional before starting, especially if you have any health condition, are pregnant, or have been inactive for a long time. Stop and seek help if you feel pain, dizziness, or shortness of breath.

4. Your content & data

The information you enter stays on your device (see the Privacy Policy). You're responsible for keeping your own backups. We can't recover data stored only on your device.

5. Our content

The Day One name, logo, text, designs, programs, and animations are owned by CRESCO and protected by law. You may not copy, redistribute, or sell them without our permission. You get a limited, personal licence to use the app as intended.

6. No warranties

Day One is provided "as is," without warranties of any kind. We don't promise it will be error-free, uninterrupted, or produce any particular fitness result.

7. Limitation of liability

To the fullest extent allowed by law, CRESCO is not liable for any injury, loss, or damage arising from your use of Day One, including from exercising or following any guidance in the app. Your use is at your own risk.

8. Changes & ending

We may update the app or these terms. If we change the terms, we'll update the date above. We may also stop offering the service. You can stop using Day One any time by uninstalling it.

9. Governing law & contact
