Fast Tracker Privacy Policy

Last updated: 21 October 2026

This policy applies to the Intermittent Fasting Tracker app for Android and iOS, named Fast Tracker on the home screen and published in the app stores as auratics.

In short

• Fast Tracker works without an account, and then your fasts stay on your phone.
• If you turn on Backup and sync, signing in with Google or Apple, and agree, a copy of your fasts is kept on our server in the European Union so you can restore it and use it on another phone. You can delete it at any time.
• The app is free because it shows ads from Google AdMob. In the European Economic Area, the United Kingdom and Switzerland, you decide whether those ads are personalised.
• We do not sell your data.

1. What stays on your phone

• Your fasts: when each one started and ended, and its goal.
• The fast you are running now, and your default goal.
• Your settings, such as the theme and reminders.

Without Backup and sync, none of this is sent to us or to anyone else, and uninstalling the app deletes it.

2. Backup and sync (optional)

Backup and sync is off until you turn it on in Settings. It asks for your consent first, and only then signs you in.

What we store, on Supabase in Frankfurt, Germany:

• your account: an account ID and the email address that Google or Apple gives us (with Apple, this can be a private relay address);
• your fasts: when each started and ended, its goal, and when it last changed;
• for a fast you delete, only its ID and when it was deleted, so your other phones delete it too;
• when you gave your consent.

What for: only to keep a copy of your fasts and to show the same fasts on every phone you sign in on. Nobody else can see them: every account can read and change only its own data.

Signing in. Google or Apple confirms who you are. They learn that you signed in to Fast Tracker, under their own privacy policies: Google and Apple.

Signing out stops backup and leaves your fasts on the phone. Deleting your account (section 9) removes the account and every fast stored with it.

3. Your health

Fasting times can say something about your health, which the GDPR treats as a special category of data. Without Backup and sync they never leave your phone. With it, we store them only because you explicitly agreed, and we never share them with Google, with advertisers or with anyone else.

Fast Tracker gives general information, not medical advice. Talk to a doctor before fasting, especially if you are pregnant or breastfeeding, have diabetes or another medical condition, take medication, or have had an eating disorder.

4. Notifications

If you turn on reminders, such as a notice when you reach your goal, they are scheduled on your phone. Nothing is sent to us or to another server to deliver them. You can turn them off in the app or in your phone’s settings.

5. Advertising

Fast Tracker shows a banner ad from Google AdMob. To show ads, measure them and, where you allow it, personalise them, Google may collect:

• device information, such as the model and operating system;
• your IP address and approximate location derived from it;
• how you interact with ads;
• on Android, your device’s advertising ID.

On iOS, the app does not ask for tracking permission and does not read your device’s advertising identifier (IDFA). Your fasts and your account are never shared with Google AdMob.

European Economic Area, United Kingdom and Switzerland. When you first open the app, Google’s consent form asks whether ads may be personalised. You can change your choice at any time in the app’s settings.

Everywhere else. You can reset your advertising ID or turn off personalised ads in your phone’s settings.

Google processes this data under its own privacy policy: policies.google.com/privacy. How Google uses data from apps that use its services: policies.google.com/technologies/partner-sites.

6. Services the app connects to

Provider	Purpose	What it receives	Location
Google (AdMob)	Ads	As described in section 5	United States
Expo (650 Industries, Inc.)	Downloading app updates	Device type, app version and a random installation ID	United States
GitHub, Inc. (GitHub Pages)	Checking whether a newer version of the app is available	Nothing beyond the request itself; the comparison happens on your phone	United States
Supabase, Inc.	Backup and sync, only if you turn it on	As described in section 2	Germany (Frankfurt)
Google or Apple	Signing in, only if you turn on Backup and sync	That you are signing in to Fast Tracker	United States

Like any request over the internet, each of these also reaches the provider with your IP address. Without Backup and sync, none of them receives your fasts.

7. Legal bases (EEA and UK)

• Backup and sync: your explicit consent (GDPR Articles 6(1)(a) and 9(2)(a)). You can withdraw it at any time by deleting your account.
• Personalised ads: your consent. You can withdraw it at any time in the app’s settings.
• Non-personalised ads and ad measurement: our legitimate interest in offering the app for free.
• Update checks: our legitimate interest in keeping the app working and secure.

8. How long data is kept

• On your phone: until you delete it or uninstall the app.
• Your account and its fasts on our server: until you delete the account.
• Google, Apple, Expo, GitHub and Supabase keep the data they receive according to their own policies.

9. Deleting your data

• One fast: open History, tap the fast, then tap Delete. With Backup and sync, it is deleted on your other phones too.
• Your account and its backup: Settings → Backup and sync → Delete account. The fasts on your phone stay.
• Everything on the phone: Settings → Delete all data, or uninstall the app.
• Without the app: write to auratics.studio@gmail.com from the email address of your account, and we delete the account within 30 days.
• Advertising data: reset or delete your advertising ID in your phone’s settings, or manage Google’s data at myadcenter.google.com.

Step by step: Deleting your data

10. Your rights

If you are in the EEA or the UK, you have the right to access, correct and delete your personal data, to restrict or object to its processing, to data portability, and to withdraw consent. You also have the right to complain to your local data protection authority.

For a copy of what we store about your account, or any other request, write to auratics.studio@gmail.com and we will reply within 30 days.

11. Security

Your fasts are stored in the app’s private storage on your phone, which other apps cannot read. Every connection the app makes is encrypted (TLS). On our server, row level security limits every account to its own data.

12. Children

Fast Tracker is not directed at children under 13, or under 16 in countries where that is the age of digital consent. We do not knowingly collect data from children.

13. Changes

We may update this policy. The current version is always on this page, with the date at the top.
