Privacy Policy

Fastly itself collects none of your data, and it has no account or sign-up. We run no server that receives your information. Your fasts and start times, fasting plans, weight, body measurements, water logs and settings are stored only on your device and are never sent to us. The app connects to the internet for ads (see Advertising), for the optional Fastly Pro purchase on Android (see Purchases), and when you tap a link to a source, which opens in your browser. The app's typeface is bundled with the app, so nothing is downloaded to display it.

Since we do not collect any user data, there is no information for us to use or process. Your fasting history, weight and plan data stay on your device and are used only inside the app to run the timer, show fasting stages, charts and streaks, and schedule your reminders.

We do not share your data with third parties, because we do not collect it. Your fasting history and progress remain on your device unless you tap Share to send a progress card through your system share sheet; nothing is shared until you choose to, and the card goes wherever you send it. The only other information that leaves your device is what Google AdMob and its mediation partners receive to show ads (described below) and, on Android, what Google Play handles for the optional Pro purchase.

Fastly is supported by ads served through Google AdMob and its mediation partners Unity Ads, ironSource (Unity LevelPlay) and Liftoff (Vungle), including optional rewarded ads that play only when you tap to watch one. To show and measure ads, these companies may access your device's advertising identifier and other device identifiers, your IP address and the approximate location derived from it, how you interact with ads, and diagnostic and device information (such as device model and operating system). Fastly does not put your fasting, weight, body-measurement, water or plan data into ad requests.

Where the law requires it, Fastly asks for your consent through Google's consent form before ads are requested: in the EEA, the UK and Switzerland you are asked first, and in some US states the form lets you opt out. Your choice is saved on your device, and Settings › Privacy choices lets you review or change it at any time. Ads may be personalised only as the choice you make allows. On iPhone and iPad, after any consent form, Fastly asks for App Tracking Transparency permission: your advertising identifier is used only if you allow tracking, otherwise ads are not personalised, and you can change this at any time in iOS Settings › Privacy & Security › Tracking.

Learn more in the privacy policies of Google (https://policies.google.com/privacy), Unity Ads and ironSource (https://unity.com/legal/game-player-and-app-user-privacy-policy) and Liftoff (https://liftoff.ai/privacy-policy/). You can also reset or limit your advertising identifier in your device settings.

On Android, Fastly offers an optional one-time purchase, Fastly Pro, through Google Play. Google Play processes the payment; we receive no card or payment details, and the purchase is tied to your Google Play account so it can be restored on a reinstall or a new device. Fastly has no in-app purchases on iPhone and iPad.

Fastly sends local notifications to remind you about your fast. They are scheduled on your device, and no push-notification service of ours is involved. Your device asks for notification permission, and you can turn reminders off in the app or in your device settings.

On Android, an optional home-screen widget shows your current fast. It reads the fast's details from data stored on your device and sends nothing anywhere.

The citations in Fastly's articles link to their sources, such as PubMed or a journal's DOI page. Tapping one opens the page in your browser, and Fastly sends that site nothing about you; the site then handles your visit under its own policy. Sharing a progress card uses your system share sheet, and only when you choose to share.

Your fasting, weight, body-measurement, water and plan data are stored locally in the app's private storage on your device, protected by your device's own security. Fastly does not add its own encryption on top of that. A card you share is an ordinary image or text that goes wherever you send it.

Since we do not collect any user data, we do not retain any personal information on external servers. Everything Fastly stores is on your device. You can delete individual fasts and weight entries inside the app, but there is currently no button that deletes all your data at once. To remove everything, uninstall the app or, on Android, clear the app's storage in your device settings. Google keeps whatever it keeps for ads and purchases under its own policies, which we do not control.

Fastly is an intermittent fasting timer and self-tracking tool for general wellness and informational purposes only. It is not medical advice, and it is not a medical device: it does not provide 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 13 ("Children"). Fastly is designed for adults and is rated 18+ in the app stores. We do not knowingly collect personally identifiable information from children under 13. If you become aware that a child has provided us with personal data, please contact us at hello@microappdigital.com 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.
