Welcome to Fastly. These Terms of Use ("Terms") govern your access to and use of the Fastly - Fast Timer & Tracker mobile application (the "App") provided by 23apps ("we", "us", or "our"). By downloading, installing, or using the App, you agree to be bound by these Terms. If you do not agree, do not use the App.
Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to download and use the App on Apple-branded devices that you own or control, for your personal, non-commercial use. This license is also subject to the Apple Media Services Terms and Conditions and the Licensed Application End User License Agreement.
Fastly is an informational and habit-tracking tool. It is not a medical device and does not provide medical advice, diagnosis, or treatment. Intermittent fasting may not be appropriate for everyone, including but not limited to individuals who are pregnant or breastfeeding, under 18, have a history of eating disorders, diabetes, low blood pressure, or other medical conditions, or are taking medications that require food intake.
You should consult a qualified healthcare provider before starting any fasting program or making significant changes to your diet, exercise, or health routine. Never disregard professional medical advice or delay seeking it because of information obtained through the App. You use the App at your own risk and are solely responsible for your health decisions.
The App offers optional auto-renewing subscriptions ("Fastly Pro") that unlock additional features such as unlimited history, advanced charts, and CSV export. Current pricing is displayed in the App before you complete a purchase.
Purchases made through the App Store are subject to Apple's refund policy. We do not process refunds directly. To request a refund, please contact Apple Support.
You retain all rights to the data you enter into the App, including fasting sessions, weight entries, and notes. The App stores your data locally on your device and, if you enable iCloud sync, in your private iCloud container. Please see our Privacy Policy for details on how your data is handled.
You agree not to:
The App, including its design, graphics, text, and code, is owned by 23apps and is protected by copyright, trademark, and other intellectual property laws. These Terms do not grant you any rights to our trademarks or branding.
The App is provided "as is" and "as available" without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the App will be uninterrupted, error-free, or free of harmful components.
To the maximum extent permitted by law, 23apps and its affiliates shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, data, use, or goodwill, arising out of or in connection with your use of the App. Our total aggregate liability for any claim arising out of or relating to these Terms or the App shall not exceed the amount you paid to us in the twelve months preceding the claim, or USD $10 if no payment was made.
You may stop using the App at any time. We may suspend or terminate your access to the App if you violate these Terms. Upon termination, the license granted to you in Section 1 ends immediately.
We may update these Terms from time to time. We will post the updated Terms on this page and revise the "Last updated" date. Your continued use of the App after changes take effect constitutes your acceptance of the updated Terms.
These Terms are governed by and construed in accordance with the laws applicable to 23apps, without regard to conflict of law principles. Any disputes shall be resolved in the courts of competent jurisdiction where 23apps operates.
