Privacy Policy

Last updated: 22 April 2026

FansBall Knowledge ("we", "us", "our") is a football fantasy and knowledge platform operated by Sandeep Khadka. This policy explains what data we collect when you use the Ball Knowledge mobile app and website, why we collect it, who we share it with, and what rights you have over it.

By creating an account or using the app, you agree to this policy. If you disagree, please don't use the service.

1. Data we collect

Category	Examples	Source
Account	Email, display name, profile picture, authentication provider (Google, email)	You, Google OAuth
Gameplay	Fantasy team picks, captain choices, daily-challenge answers, LFS picks, quiz attempts, points, streaks	Your in-app activity
Social	Leagues you join, stories you like/save, reports you file	Your in-app activity
Technical	Device type, OS version, app version, crash reports, Expo push token	App + Sentry
Advertising	Advertising identifier (only if you grant permission via iOS ATT prompt), ad interaction events	Google AdMob

2. Why we collect it

Run the app — sign you in, persist your teams and progress across devices, compute leaderboards.
Send notifications — deadline reminders, captain-scored alerts, daily-challenge prompts. You control this via your device settings.
Keep it working — diagnose crashes (Sentry), monitor performance, detect abuse.
Pay for the service — show AdMob ads; rewarded ads unlock in-app hints.
Comply with legal requests — retain data only as long as required.

3. Who we share it with

We share the minimum necessary with trusted service providers who are contractually bound to handle data on our behalf:

Provider	Purpose	Data shared
Supabase	Authentication + database hosting	Email, auth identifiers, all gameplay data
Cloudinary	Image hosting (avatars, story images)	Images you upload
Expo (Push)	Delivering push notifications	Push token, notification content
Sentry	Crash reporting	Device info, stack traces, user ID (anonymized where possible)
Google AdMob	Serving ads	Advertising ID (with your consent), approximate location
Render	Backend API hosting	All data flows through this infrastructure

We do not sell your personal data. We do not share it with advertisers or data brokers beyond the named providers above.

4. Your rights

You can, at any time:

Access your data — use the in-app "Export My Data" option (Profile → Settings → Export).
Delete your account — use "Delete Account" in Profile → Settings. This permanently removes your user row and all cascaded data (teams, picks, completions, streaks, league memberships, push token, stored images). Deletion is immediate and cannot be undone.
Withdraw tracking consent (iOS) — iOS Settings → FansBall Knowledge → Allow Tracking toggle.
Disable notifications — iOS/Android Settings → FansBall Knowledge → Notifications.
Contact us — email support@fansballknowledge.com for questions or concerns.

5. Children

FansBall Knowledge is not intended for children under 13. We do not knowingly collect data from children under 13. If you believe a child has given us personal data, contact us and we'll remove it.

6. Security

All data is transmitted over HTTPS. Passwords are hashed with bcrypt. Push tokens and authentication tokens are stored in encrypted secure storage on-device (Expo SecureStore / iOS Keychain / Android Keystore). No system is perfectly secure, but we follow current best practices and patch promptly when advisories are published.

7. Data retention

We retain your account data for as long as your account is active. On deletion, the account row and all cascade-linked data are deleted immediately. Sentry crash reports are retained for 30 days. Backup snapshots may contain data for up to 30 days after deletion; these are not used for anything except disaster recovery.

8. Changes to this policy

We may update this policy as the app evolves. Significant changes will be announced in-app. The "Last updated" date at the top always reflects the current version.
