Slitherlink Privacy Policy
Developer: An Suhan (안수한) — glorygem195@gmail.com
Package: slitherlink.com.puzzle.glorygem.slitherlink_project
1. What we collect and why
| Data | Purpose | When |
|---|---|---|
| Email address | Create your account, sign you in, reset your password | Only if you sign up |
| Account identifier | Link your saved progress to your account | Only if you sign up |
| Puzzle progress | Restore your progress on any device you sign in to | Only if you sign up |
| App usage data | Understand which screens and features are used, so the app can be improved | Always, while the app runs |
Settings and cached progress are kept on your device only and are never uploaded. You can play without an account; in that case no email address or progress is stored on a server.
2. Processors
The app uses Google Firebase.
| Processor | Service |
|---|---|
| Google LLC (Firebase Authentication) | Account sign-in |
| Google LLC (Cloud Firestore) | Storing progress |
| Google LLC (Firebase Analytics) | Usage statistics |
We do not sell or share your data with anyone else, and there is no advertising in the app at this time.
3. International transfer
To provide the services above, your data may be transferred outside the Republic of Korea.
| Item | Detail |
|---|---|
| Recipient | Google LLC (operator of Firebase) |
| Countries | The United States and other countries where Google operates data centres |
| Data transferred | Email address, account identifier, puzzle progress, app usage data |
| Purpose | Account authentication, saving and restoring progress, usage statistics |
| Method | Transferred over encrypted connections while you use the app |
| Retention | Until you delete your account (usage statistics: Firebase’s default retention period) |
If you prefer not to have your data transferred, you can play without signing in, or delete your account. In that case progress cannot be saved to or restored from an account.
4. Retention and destruction
- Account data and progress are kept until you delete your account, and are deleted at that moment.
- If you request deletion by email, we delete the data within 7 days of verifying your request.
- Electronic records are deleted in a way that cannot be recovered.
- Usage statistics are not personally identifiable and are removed automatically after Firebase Analytics’ standard retention period.
5. Deleting your account and data
In the app, sign in and open the account screen (where the sign-out button is), then choose 탈퇴하기 (Withdraw). For security you may be asked to sign in again first. Deleting removes your saved progress and your account permanently. If you have already uninstalled the app, email glorygem195@gmail.com from your account address and we will delete it within 7 days. Details: /slitherlink/account-deletion/
6. Security
All communication with Firebase uses encrypted connections, and Firestore access rules restrict each account to its own data. Passwords are handled by Firebase Authentication and are never visible to the developer.
7. Children
The app is intended for users aged 13 and over and is not directed to children.
8. Your rights
You may request access to, correction of, deletion of, or suspension of processing of your data at any time by emailing glorygem195@gmail.com. Requests are handled promptly after we verify your identity.
