This guide describes Silent Key’s actual product model and the general privacy concepts around it. It avoids guarantees the service cannot technically make.
Before starting a conversation
Confirm why the other person needs to contact you and share the minimum identifier required. Send your SK-ID privately rather than publishing it. Use a nickname and profile image that do not reveal unnecessary personal details. Keep the Google account used for sign-in protected with a strong password, current recovery information and two-step verification when available.
Check the service’s security model before sending sensitive material. Silent Key is moderated and Firebase-backed; it is not presented as end-to-end encrypted. That makes it suitable for ordinary conversation, not for secrets that require the provider to be technically unable to read the content.
During the conversation
Pause before sharing addresses, live location, school schedules, financial information, login credentials or verification codes. A temporary timer does not stop a recipient from copying the content. Be cautious when someone creates urgency, asks you to move to an unfamiliar platform or requests proof through private documents.
Keep the conversation inside the expected context. Unexpected links, files or requests should be treated as untrusted until independently verified. Silent Key currently focuses on text and profile controls; that narrower design is useful because fewer media paths mean fewer places for hidden content to arrive.
Use blocking early
Blocking is not an admission that something dramatic happened. It is a routine boundary tool. Use it when a person repeatedly contacts you after being asked to stop, pressures you for information or makes the conversation unsafe. Continuing to argue often gives an abusive person more attention and more material to misuse.
Blocking should stop ordinary one-to-one contact in the application. Keep in mind that a determined person may use another account or a different service, so review what identifying information has already been shared.
Report with useful context
A useful report identifies the user or message, selects the closest reason and adds concise context. Do not embellish. Administrators need enough information to understand the pattern, not a novel written during peak frustration. Preserve relevant details before temporary history expires if they are needed for a report.
Moderation can review reports, remove messages, suspend accounts or block accounts. Because moderation requires access, the service does not claim end-to-end encryption. That trade-off should be understood rather than hidden behind a lock graphic.
After the conversation
Remove the chat from your own list when you no longer need quick access, but understand that this may not delete the other participant’s view or all server records. Temporary messages expire according to their timestamps and cleanup process. Conversation connections can remain even when history is empty.
Review browser notification permissions on shared devices. Log out when using a device you do not control. If the Google account may be compromised, secure that account first because Silent Key relies on Google Sign-In rather than a separate password.
Escalate serious problems
For immediate danger, threats, exploitation, fraud or other serious harm, use trusted adults and appropriate local authorities or support channels. An in-app report is a product moderation tool, not an emergency service. Keep evidence through safe, lawful means when it may be needed, even if that means the material should not be deleted automatically.
