Privacy Policy

1. Who We Are

Slim to Win ("we", "us") provides the Slim to Win mobile app and the website slim-to-win.com. This Privacy Policy explains what personal data we collect when you use the app, why we collect it, how long we keep it, and how you can delete it.

Contact: support.team@slim-to-win.com

2. Information We Collect

Information you give us:

• Account data: email address, password (stored only as a secure hash), username, display name, profile photo, year of birth and preferred language
• Profile and onboarding answers: fitness goals, activity level and the answers you give in the About You step
• Body measurements: weight and body measurements you enter
• Progress photos and videos: body progress photos, elimination round videos and meal photos you upload
• Nutrition entries: meals and foods you log
• Workout records: workouts completed, check-ins and challenge progress
• Community content: feed posts, replies, votes, reports you submit and users you block
• Support requests: support tickets, messages and attachments you send us
• Legal records: when you accepted the Terms of Service and Privacy Policy and signed the Medical Waiver

Health data (only with your permission):

• If you connect Apple Health, Health Connect or Huawei Health, the app reads your daily step count and active calories burned. The app only reads this data; it never writes to your health app.

Information collected automatically:

• Device and session data: device model, operating system, app version and a push notification token
• Approximate location: when you sign in, the city and country are derived from your IP address and stored with your sign-in session so you can recognise your own sign-ins and we can detect suspicious ones. We do not collect precise (GPS) location.

We do not use advertising identifiers, we do not track you across other companies' apps or websites, and the app contains no advertising. The current version of the app does not use product analytics.

3. How We Use Your Information

We use your information to:

• Create and secure your account and sign you in
• Run fitness challenges: registration, daily workouts, check-ins, progress tracking, eliminations, community voting and results
• Show your progress, measurements, photos and step counts to you in the app
• Operate the community feed, including reporting and blocking
• Send notifications and emails about your account and the challenges you join (you can change notification preferences in Settings)
• Answer support requests
• Detect fraud, cheating and abuse, and keep the service secure

Health data from Apple Health, Health Connect or Huawei Health is used only to show your step and active calorie totals and challenge progress. It is never used for advertising or marketing, never sold, and never shared with third parties for their own purposes.

4. What Other Users Can See

• Your username, profile photo and the posts and replies you publish in the community feed are visible to other users
• Other participants in a challenge can see your challenge progress and rankings
• During community voting, progress photos submitted for voting are shown to other participants anonymously

You can block another user from the "..." menu on their post or reply. Blocked users are managed in Settings > Privacy.

5. Information Sharing

We do not sell your personal information. We share it only with service providers that help us run the app, and only for that purpose:

• Hosting and storage of the app's backend and files (our own servers)
• Email delivery provider, to send account and challenge emails
• Push notification services (Expo, Apple Push Notification service and Firebase Cloud Messaging), to deliver notifications to your device
• IP geolocation service, to derive the approximate city and country of a sign-in from its IP address

We may also disclose information when required by law, or to protect the rights, safety and property of our users and Slim to Win.

6. Data Security

Data is encrypted in transit (HTTPS). Sign-in tokens are stored in the secure storage of your device. Access to personal data on our servers is limited to authorised staff. No method of storage or transmission is completely secure, but we work to protect your data and fix issues quickly.

7. Data Retention

We keep your data while your account is active. When you delete your account, it is scheduled for deletion and permanently processed after a 30-day grace period, during which you can cancel by signing in. After the grace period, your email address, name, username and personal profile fields are removed and your device identifiers are cleared, so the remaining records are no longer linked to you.

If you also want your photos, videos, posts and other content removed, include that in your request (see section 8) and we will delete them. Records we must keep by law are kept only as long as required.

8. Your Rights and Deleting Your Account

You can:

• Access and update your profile data in the app
• Export your data from Settings > Privacy
• Change notification and privacy preferences in Settings
• Delete your account in the app: Settings > Account > Delete Account
• Request deletion without the app: follow the instructions at https://slim-to-win.com/delete-account or email support.team@slim-to-win.com with the subject "Account deletion request" from the email address of your account

To exercise any other right, email support.team@slim-to-win.com. We reply within 30 days.

9. Children

Slim to Win is intended for adults aged 18 and over. We do not knowingly collect data from children. If you believe a child has created an account, contact us and we will delete it.

10. Changes to This Policy

We may update this Privacy Policy. When we make material changes, we will update the version and effective date and show the new policy in the app. The current version is always available at https://slim-to-win.com/privacy.
