Enforce application rules
Maintain a safe community
Prevent misuse
Comply with legal obligations
A report does not automatically result in deletion of a message. Authorized administrators may review reports and decide whether further action is appropriate.

With technology and service providers used to operate the application

These measures may include:
Firebase Authentication
Firestore security rules
Server-side authorization checks
Role-based access restrictions

13. Data Retention
We retain personal information only for as long as necessary to provide the application's services, administer the dojo, protect the service, or comply with applicable legal obligations.
While your account remains active, relevant account, membership, attendance, rank, progress, subscription, chat, and other information may remain stored as necessary to provide the application's functionality.
If you permanently delete your account through the application, personal data associated with your account is deleted as described in the Account and Data Deletion section below.

Information that is no longer required may be deleted or, where appropriate, anonymized.
14. Account and Data Deletion
You can permanently delete your account directly from within the application.
To delete your account, open your Profile and select Delete Account.
You will be asked to confirm the action before deletion begins.
When account deletion is successfully completed, the application deletes personal account information associated with the account, including, where applicable:
The Firebase Authentication account
The application's user account record
Linked current and legacy member records associated with the account
Member-owned subcollections and records
Attendance history
Rank and progress information
Subscription records stored as part of the member profile
Registration and account-linking request records
Chat messages authored by the user
Chat read receipts
Device notification tokens associated with the account

Deleting your account does not necessarily delete shared information belonging to other users or shared dojo records.
Certain administrative, financial, accounting, legal, security, or record-keeping information may be retained where necessary or required by applicable law.
