Visible status can show availability at a moment. It does not reveal a complete conversation history, a location, or the reason someone used an app.
Separate presence from conversation
WhatsApp and Telegram web clients display the activity signals available under their own settings. Seeing someone online does not establish who they are talking to or whether they read your message.
WhatsApp’s last seen and online help explains visibility limits. Do not treat a missing status as proof of blocking, inactivity, or deception.
What Mona is for
Mona is presented as an online-activity tool. Use only supported, visible signals and verify the available platforms and features in the current app. This is not a verified GPS location or message-reading workflow.
An organized activity history can help review recorded timings, but missing observations and delayed notifications remain possible. Coinciding sessions are not evidence of communication.
Agree on the purpose
Ask the people involved what monitoring they permit and how the information will be used. Consider applicable law, account authorization, and platform rules.
For urgent wellbeing questions, call or contact the person directly. A timeline is not an emergency service and cannot establish that someone is safe.
