Notification access is different from permission to send notifications. Understand the risks of message previews, Android 15’s limits, and how to review app access.
Prompt injection can divert an assistant with chat access. Understand E2EE boundaries, necessary permissions, and practical controls to reduce data leaks.
A safety number is a human-readable fingerprint of the encryption keys behind a chat. Here is what comparing it out of band actually proves, why it changes, and why no warning flag can replace the ritual.
What does a safety number verify? Learn how to compare it with a contact, respond to key changes and distinguish manual verification from key transparency.
Encrypting messages in transit does not necessarily protect a backup stored in the cloud. This guide explains where backups reside, who may have access to them and what questions to ask any messaging service.
How can you check a fake administrator, a bogus prize or a cryptocurrency offer? A guide to stopping, verifying independently and protecting your account, including the limits of end-to-end encryption.
Pegasus and Graphite target devices, not just unlocked screens. Learn what the forensic reports show, where E2EE stops and how to respond to a spyware warning.
An app lock helps with casual access, but malware or remote control may abuse an unlocked messenger. Review Android permissions and respond from a trusted device.
Look beyond the label: algorithm choice, key custody, identity checks, backups and independent evidence determine what a messenger actually protects.
MLS uses tree-based group key agreement; Livara describes a sender-key design. Compare membership changes, recovery, overhead and evidence without a false winner.
What ML-KEM-768 does in a messenger, why a hybrid design also uses P-256, and which security questions FIPS 203 does not answer.
Pulse comes from the people building Livara. Read the bylines, follow the sources, and explore the trade-offs behind the technology.
