1. Data Collection: We collect your chosen username and a unique user ID generated by Firebase Authentication for the purpose of identifying you within chat rooms. Room codes and messages sent within rooms are stored temporarily on our Firebase Firestore database to facilitate real-time communication. We do NOT collect any personally identifiable information beyond your chosen username and the Firebase-generated user ID.
2. Data Usage: Your username and user ID are used solely to display your identity in chat rooms and manage your participation. Room data (including messages) is used to enable chat functionality. We do not use your data for advertising, tracking, or any other commercial purposes.
3. Data Storage and Deletion: Chat rooms and their messages are designed to be temporary. Rooms are automatically deleted if they become empty (no participants) or if there is no activity (no messages sent or users joining/leaving) for 15 minutes. Permanent rooms, if enabled by the host and secured with a password, will persist even when empty, but will be deleted after 1 week of inactivity (no messages sent or users joining/leaving).
4. Security: We use Firebase Firestore, which provides robust security features. However, please remember that random and unmoderated chat rooms inherently carry risks. Do NOT share sensitive personal information (e.g., real name, address, phone password, financial details) in Textroll chat rooms.
5. Encryption Algorithm (Deprecated): All sensitive data, including chat messages, room codes, usernames, and room passwords, are encrypted using a custom substitution cipher (Hashtik V2). While this algorithm provides a basic level of obfuscation, it is considered **deprecated** and is not cryptographically robust against advanced attacks. It is primarily used here to prevent casual snooping of data directly from the database. For highly sensitive communications, a more modern and robust encryption standard would be required. This algorithm is intended for future updates to a more secure method.
6. Changes to this Policy: We may update this privacy policy from time to time. Any changes will be reflected directly within the app. Your continued use of the app after such changes constitutes your acceptance of the new policy.
7. Contact: For any privacy-related questions, please contact us through the platform where you accessed this application.
