Privacy Policy

At Fastly, we prioritize your privacy and data security. We do not collect any personal data from our users. Everything you enter — your fasts and start times, fasting plans, weight and body measurements, water logs, reminders, goals, and settings — is stored locally on your device and is never transmitted to any server or to us.

Since we do not collect any user data, there is no information for us to use or process. All fasting calculations, stage detection, charts, streaks, and reminders are generated entirely on your device, without requiring any personal data, ensuring complete privacy for our users.

We do not share any user data with third parties because we do not collect any user data. Your fasting history and progress remain on your device unless you explicitly tap Share to send a progress or achievement card via your system share sheet.

Fastly is supported by ads served through Google AdMob. AdMob may collect a non-personal advertising identifier from your device to deliver non-personalized ads, frequency capping, and aggregate measurement. This data is handled by Google in accordance with the Google AdMob Privacy Policy. The app itself does not receive, store, or share this identifier. You can reset or limit ad tracking from your device's system settings at any time. Fastly also offers an optional one-time in-app purchase to remove ads.

The security of your data is of utmost importance to us. Although we do not collect any personal data, we employ stringent security measures to protect any information processed through our application. All data is stored locally on your device using encrypted local storage. We are committed to maintaining a secure environment for all users.

Since we do not collect any user data, we do not retain any personal information on external servers. All application data is stored locally on your device and can be deleted at any time by clearing the app's data within the app or by uninstalling the application.

Fastly is an intermittent fasting timer and self-tracking tool for general wellness and informational purposes only. It is not a medical device and does not provide medical advice, diagnosis, or treatment. Always consult a qualified healthcare professional before beginning any fasting, diet, or weight-loss program, especially if you are pregnant, breastfeeding, under 18, or have a medical condition.

Our application is not intended for use by anyone under the age of 18 ("Children"). We do not knowingly collect personally identifiable information from children. If you become aware that a child has provided us with personal data, please contact us so that we can take steps to remove such information.

We may update our Privacy Policy from time to time to reflect changes in our practices or for other operational, legal, or regulatory reasons. We will notify you of any changes by posting the new Privacy Policy on this page. You are advised to review this Privacy Policy periodically for any changes. Changes to this Privacy Policy are effective when they are posted on this page.
