Sidekick Privacy Policy

Last updated: 5 November 2026

This policy explains how the Sidekick mobile app ("Sidekick", "the app", "we") handles your information. In short: you sign in with Apple or Google to use Sidekick. Your workouts, food logs and body data live on your phone and are backed up to your account on Sidekick's own server, so they follow you to a new phone. We never sell them or use them for ads. Anonymous usage and crash data help us fix bugs, and you can turn that off.

1. Data stored on your phone

Your profile (name, age, height, weight, goal), training plan, workout history, food and water logs, weight and body measurements, fasting history and settings are stored on your device. Your phone's own backup (iCloud or Google) may include them.

1a. Cloud backup

While you're signed in, Sidekick copies that same data (not progress photos, and not data read from Apple Health or Health Connect) to a backup tied to your account on Sidekick's own server (249apps.com, hosted by Hostinger), so you can restore it on a new phone. It is sent over an encrypted connection, kept as one copy that each new backup replaces, and deleted when you delete your account. It is used to restore your data and, when you contact us or something goes wrong with your account, the Sidekick team can see a summary of it (your goal and plan, workouts, weight and food-log totals, app settings) to help you. We never sell it, share it for advertising, or use it to train AI. You can restore it from Me › Backup.

2. Your account (Sign in with Apple or Google)

Sidekick needs an account. When you sign in, we use Google Firebase Authentication to create it. It stores your name, email address (Apple may give a private relay address) and a unique account ID. We use these only to provide your account and its backup.

While you're signed in, the app also keeps a short account summary on Sidekick's own server (249apps.com, hosted by Hostinger): your name and email, how you signed in, your phone's platform (iOS or Android), the app version, your language setting, whether you have Sidekick Pro, when you joined and when you last opened the app. We use it to support you and to keep the app working on the versions people use. It holds no workout, food, body or health data, and it is deleted with your account.

You can delete your account at any time in Me › Account › Delete account. This permanently deletes the account and, for Apple, revokes Sidekick's access to your Apple ID.

3. Usage analytics and crash reports

To find bugs and improve the app, Sidekick uses Google Firebase Analytics and Firebase Crashlytics. They collect:

This data is not linked to your account or name, is not used for advertising, and is not sold. Sidekick does not collect any advertising ID and does not track you across other apps or websites. You can turn it off any time in Me › Privacy › Share usage data.

3a. Feedback and purchases

If you send feedback from Me › Send feedback, we store your message, the kind of feedback, your phone's platform, app version and language, and, if you add it or are signed in, your email and account ID, so we can read it and reply. It is kept until the issue is handled, at most 2 years.

Sidekick Pro is sold through the App Store or Google Play; Apple or Google handle payment and we never see your card details. We use RevenueCat to check which purchases are active. It receives an app user ID (your account ID if you're signed in, otherwise a random ID) and your purchase history. RevenueCat's privacy policy: https://www.revenuecat.com/privacy

4. Apple Health and Health Connect

If you turn on Health sync, Sidekick reads your steps and active energy to fill your activity rings and writes finished workouts and weigh-ins. Health data stays on your device. It is never sent to us, to Firebase, or to any third party, and is never used for advertising or analytics. You can turn access off in the Health or Health Connect app at any time.

5. Camera

The camera is used only to scan barcodes and nutrition labels. Images are processed on your device and are not uploaded or kept.

6. Food lookups

When you scan a barcode, the barcode number only is sent to Open Food Facts (openfoodfacts.org) and the USDA FoodData Central service to look up the product. No personal information is sent with it. Searching the built-in food list works offline.

7. Notifications

Workout reminders are scheduled on your device. No notification data leaves your phone.

8. Children

Sidekick is not directed at children under 13 (under 16 in the EU) and we do not knowingly collect their data.

9. Keeping and deleting data

Depending on where you live (for example under the GDPR or CCPA), you may have rights to access, correct or delete your data, or to object to its use. Contact us to use them.
