Privacy Policy

This Privacy Policy applies to the Fastiq mobile application (the “App”) and this website. By using Fastiq, you agree to the practices described here. If you do not agree, please do not use the App.

Information we collect

Information you provide

• Account information. If you choose to create an account, we collect your email address. We use a one-time email code to sign you in; we do not store a password.
• Health and fitness information. The profile and goals you enter — such as height, weight, age, sex, activity level, fasting schedule, logged meals, calories, macronutrients, and weight history.
• Food photos and images. Photos of meals, nutrition labels, and barcodes you submit so the App can estimate nutrition information.
• Community and group-fast information. Your display name, group-fast title, coach updates, and other content you choose to share through community features.

Information collected automatically

• Purchase information. Whether you hold an active Fastiq Pro subscription. Payments are processed by Apple or Google, depending on where you subscribed; we do not receive or store your full payment-card details.
• Basic diagnostic and usage data. Limited technical information needed to operate the App, diagnose problems, and prevent abuse.
• Product analytics. Screen views, app launches, onboarding progress, interactions with subscription offers, purchase outcomes, and use of meal-logging and fasting features. These records can include counts and feature-use indicators, app and device technical information, event timestamps, subscription status, and an internal Fastiq identifier used to understand repeat use. They may be linked to your account and are not fully anonymous.
• Notification token and timezone.If you allow notifications and enable a hosted-notification category, we associate an app-specific push token and your device's timezone with your Fastiq account. We use them to deliver notifications at the relevant local time and respect quiet hours.
• Hosted-fast preferences. We remember which fast invitations you have seen and which fasts you have muted, so we can avoid repeating invitations and respect your notification choices.

How we use your information

• To provide core features: fasting timers, food logging, and progress tracking.
• To estimate calories and macros from the photos, labels, and barcodes you submit.
• To calculate personalized nutrition goals from the profile information you provide.
• To back up and sync your data across your devices when you sign in.
• To manage subscriptions and restore purchases.
• To understand feature use, improve onboarding, and evaluate subscription offers.
• To announce newly scheduled hosted fasts, remind you about fasts you join, and deliver coach updates and polls, according to your notification preferences.
• To respond to support requests and keep the App secure and reliable.

Hosted fast notifications

Depending on your preferences, we send announcements when a host schedules a fast, reminders and schedule changes for fasts you join, and coach updates and polls. Notifications may contain the host's display name, the fast title, schedule information, or the coach message. We use your timezone to time reminders and delay new-fast announcements and coach notifications during quiet hours.

Notification delivery is processed on our behalf by Expo and the push notification services operated by Apple or Google. We use push tokens and notification content only to provide these features, not for advertising or cross-app tracking.

You can control new-fast announcements, hosted-fast reminders, and coach updates separately in Settings, or mute an individual fast. An invitation shown inside the App does not require notification permission. We remember that you have seen an invitation so that the same fast does not repeatedly prompt you.

Product analytics and advertising measurement

We use PostHog to process product analytics on our behalf. Session replay is disabled. We do not forward these analytics events to advertising platforms or use them to track you across other companies' apps and websites.

The revised analytics setup excludes fasting durations, fasting goals, weight, meal contents, photos, and contact details from PostHog events. Coarse indicators of feature use remain, such as whether a meal was logged or a fast was completed. Earlier app versions may have included fasting duration and goal properties; updating the App does not itself erase previously collected analytics records.

In iOS versions using our revised install-attribution setup, the App registers a fixed install signal with Apple's privacy-preserving attribution system. Apple may send a delayed attribution report to a qualifying advertising network, with information limited by Apple's privacy rules. This process does not provide your Fastiq account ID, health information, or device advertising identifier to the network. This setup does not request Apple's tracking permission or use the Meta SDK to send individual app activity or subscription events.

AI processing of meals

When you use the AI logging features, the image or text you submit is sent through our secure server to our AI provider (Google, via the Gemini API) to generate nutrition estimates that are returned to you. This processing exists solely to provide the feature you requested. Nutrition values produced by AI are estimates and may not be accurate.

How your data is stored

Fastiq is designed to work primarily on your device. Your logs are stored locally. If you create an account, your data is also backed up to our cloud infrastructure (Supabase) so it can sync across your devices. Access to your synced data is restricted to your own account.

Service providers we share data with

We do not sell your personal information. We share data only with the service providers needed to run the App, and only as necessary to provide their service:

• Apple and Google — app distribution and subscription payment processing, through the App Store and Google Play.
• Supabase — authentication and encrypted cloud storage for account backup, sync, hosted-fast preferences, and notification scheduling.
• RevenueCat — subscription management and entitlement status.
• PostHog — product analytics for understanding and improving the App, processed on our behalf in the United States.
• Google (Gemini API) — AI analysis of the meal images and text you submit.
• Expo, Apple Push Notification service, and Firebase Cloud Messaging — delivery of hosted-fast announcements, reminders, and coach notifications according to your preferences.

These providers are bound by their own terms and are expected to protect your information consistent with this policy.

Data retention and deletion

You are in control of your data at all times. You can:

• Erase all datafrom within the App (Settings → Erase all data & start over) to clear your meals, fasts, weight, and goals.
• Delete your account from within the App (Settings → Delete account). This permanently removes your account and its associated synced data from our app servers. For analytics records, contact us as described below.
• Control notifications.Turning a category off stops notifications in that category. Turning all hosted-notification categories off, signing out, or deleting your account removes the push token from Fastiq's systems. Muting a fast stops its notifications. We also remove invalid tokens when a notification service reports that the App is no longer registered.
• Contact us at support@fastiq.fit to request deletion of your data.

Signing out, resetting an analytics identifier, or deleting your app account does not automatically delete previously collected PostHog analytics records. To request access to or deletion of analytics records associated with you, email support@fastiq.fit.

Your rights

Depending on where you live, you may have rights to access, correct, export, or delete your personal information, and to withdraw consent. To exercise these rights, use the in-app controls above or email us at support@fastiq.fit.

Children

Fastiq is intended for adults aged 18 and over. It is not directed to children, and we do not knowingly collect personal information from anyone under 18. If you believe a minor has provided us information, contact us and we will delete it.

Security

We use reasonable technical and organizational measures to protect your information. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

International transfers

Your information may be processed in countries other than your own, including by the service providers listed above. Where required, we take steps to ensure your data receives an adequate level of protection.

Changes to this policy

We may update this policy from time to time. When we do, we will revise the “Last updated” date above. Material changes will be reflected here before they take effect.
