2alo is designed and operated using End-to-End Encryption (E2EE), with the primary goal of protecting user privacy and ensuring maximum data confidentiality. 1. Core Privacy Principles We cannot access the content of your messages, calls, shared files, or communications. All communications between users are protected using end-to-end encryption, meaning only the sender and intended recipient can decrypt the content. 2alo servers do not store encryption keys and have no technical ability to decrypt user content (zero-knowledge architecture). 2. Information We Do Not Collect 2alo does not collect, store, or process the following data: - Message content, voice calls, video calls, or shared files - Encryption keys for user communications - Personal contact lists stored on your device, unless explicitly permitted by the user - Audio, image, or video data outside encrypted transmission - Advertising data, tracking data, or behavioral analytics 3. Minimal Technical Information To operate the Service reliably, we may process a limited amount of technical metadata, including: - Network connection information (such as IP address at the time of connection) - Basic device information (operating system, app version) - Encrypted routing data required for message delivery This information: - Is not used for advertising - Is not used for user profiling or behavior tracking I- s not linked to message content 4. Log Data 2alo does not use analytics tools or third-party tracking systems. In limited technical circumstances (such as debugging, abuse prevention, or infrastructure protection), system-level logs may be temporarily generated to ensure service reliability and security. These logs: - Do NOT contain encrypted message content - Are processed only for operational and security purposes - Are retained for the shortest period necessary 5. Third-Party Service Providers 2alo may rely on third-party infrastructure providers (such as hosting, networking, or DNS services) to operate the Service. These providers: - Do not have access to encrypted user content - Provide infrastructure services only - Are contractually obligated to protect data confidentiality Our website and infrastructure may use services such as Cloudflare DNS to enhance security and protect against attacks. Such services may automatically process limited technical request data in accordance with their own privacy policies. 6. Information Security We implement industry-standard security measures, including: - End-to-end encryption (E2EE) - Secure server infrastructure - Strict internal access controls However, no method of electronic transmission or storage is completely secure. While we strive to protect your data, we cannot guarantee absolute security.
