Privacy Policy EN
Effective date: August 27, 2026
Overview Knotweave (“the app”) is a puzzle game where you connect numbered cells in sequence to fill the grid. This policy explains what data we collect, why, and how you can control or delete it.
Data we collect Account data (only if you choose to sign in): • Guest sign-in: an anonymous account identifier and the display name you type in. No email or password. • Google Sign-In: your Google account’s user ID, email address, and display name, provided to us by Google when you sign in. • Sign in with Apple: your Apple ID’s unique identifier and the name/email you choose to share, provided to us by Apple when you sign in.
Gameplay data: your level completion times, star ratings, hint usage, and lifetime star total, submitted to a public leaderboard under your display name and stored against your account identifier.
Local-only data: your puzzle progress, unlocked themes, and app settings (sound, haptic feedback, language) are stored only on your device.
Push notification data: if you allow notifications, we use a Firebase Cloud Messaging device token to send you daily challenge reminders. This token is not linked to your identity beyond your device.
Advertising data: the app shows ads served by Google AdMob. AdMob may use advertising identifiers (such as Apple’s IDFA, requested via the App Tracking Transparency prompt on iOS, or Android’s advertising ID) to show relevant ads and rewarded-video hints. If you decline tracking permission, or on Android generally, ads are shown without personalization.
How we use this data To let you save progress, compete on level and Daily Challenge leaderboards, remind you about new daily puzzles, and show ads that support free access to the app. We do not sell your data, and we do not use it for any purpose other than the above.
Third parties Google Firebase (Authentication, Cloud Firestore, Cloud Messaging, Cloud Functions) and Supabase host your account, leaderboard, and daily challenge data. Google AdMob, Google Sign-In, and Sign in with Apple serve ads and (optionally) sign you in. These are covered by Google’s Privacy Policy (policies.google.com/privacy), Apple’s Privacy Policy (apple.com/legal/privacy), and Supabase’s Privacy Policy (supabase.com/privacy).
Data retention & deletion Leaderboard and account data is kept until you delete it. You can permanently delete your account at any time from Profile → Request Account Deletion (or Settings → Delete Account). This triggers removal of your account and its associated profile record. Individual past leaderboard scores may remain visible as historical entries tied to a now-deleted account identifier, with no way to link them back to you afterward.
Children’s privacy Knotweave is a general-audience puzzle game and is not directed at children under 13. If you are a parent or guardian and believe your child has provided us with personal data, please contact us below and we will delete it.
Your choices You can play without signing in at all; sign-in is only required to appear on leaderboards. You can sign out or delete your account at any time from Settings or Profile. You can turn off daily reminder notifications at any time from your device’s notification settings. On iOS, you can change your ad tracking permission at any time in Settings → Privacy & Security → Tracking. On Android, you can opt out of personalized ads or reset your advertising ID at any time in Settings → Google → Ads.
Changes to this policy We may update this policy from time to time. Material changes will be reflected by updating the effective date above.
