Emergency SOS Trigger
A large emergency button starts emergency mode quickly. The app alerts saved contacts, opens a locked emergency screen, and continues until the user presses Stop Emergency.

Repeating SOS Messages
SOS messages continue at a set interval until emergency mode is stopped, with statuses like Sending, Sent, Delivered, or Failed.
Emergency Calling
When emergency mode starts, SilentGuard immediately calls the first saved emergency contact.
Location Sharing
Alerts include the latest available location. If location is unavailable, the SOS still sends and explains that location could not be attached.
Audio Evidence Recording
Pro starts emergency audio recording automatically and uploads small audio chunks every few seconds when internet is available.
Saved Emergency Recordings
If emergency mode stops before sharing, the evidence session is still saved so Pro users can share it later from SilentGuard.
Offline Audio Protection
No internet? SilentGuard records locally, keeps pending recordings on the device, and uploads automatically when internet returns.
Internet Fallback
SilentGuard tries normal SMS first. If SMS fails but internet is available, it opens sharing through apps like WhatsApp, Gmail, Telegram, Messenger, or Messages/RCS.
Emergency Contacts
Add contacts manually or pick from the phone contact list. Contacts can be saved and managed inside the app.
Volume Button Trigger
Users can enable accessibility permission for volume-button emergency trigger support, and the app shows whether it is enabled.

Important Safety Reminder
Prepare your phone before you need emergency help.
Silent Guard is designed to support your safety in emergencies, but no app can guarantee 100% life protection. For the best protection, users should always make sure their phone is ready before leaving home, travelling, meeting someone unfamiliar, or entering an unsafe situation.
Silent Guard can help send SOS alerts, location, calls, and emergency evidence, but users should still stay aware of their surroundings and contact local emergency services whenever possible.
Before relying on Silent Guard, confirm:
Quick checks for stronger emergency readiness
Internet or mobile data is turned on
Location/GPS is turned on
SMS service is available
Emergency contacts are saved correctly
Volume trigger/accessibility is enabled
Phone has battery and network coverage
Calm, transparent safety
Professional safety wording, no fear tactics.
SilentGuard supports emergency communication but cannot replace official emergency services.
✓ Free users can use core SOS protection without signup.
✓ Pro recording is for emergency evidence and starts during emergency mode.
✓ Offline recordings remain on the device until upload is possible.
✓ Users choose and manage their own emergency contacts.
✓ The emergency continues until Stop Emergency is pressed.
✓ Paid accounts are email-linked and limited to one active device.

07FAQ
Clear answers for safety-critical questions.
Does SilentGuard need internet to send SOS?+
Normal SMS uses cellular SMS service, not internet. If SMS fails and internet is available, SilentGuard can open a share option so the user can send the SOS through another app.
Can SilentGuard send SMS without mobile network?+
No. SMS depends on the phone, SIM, carrier, and mobile network. SilentGuard shows status such as Sending, Sent, Delivered, or Failed when available.
What happens when the phone has no internet?+
Pro audio can keep recording locally. Pending recordings upload automatically when internet returns.
What if location is unavailable?+
SilentGuard still sends the SOS message and explains that location is unavailable. Users should keep phone location turned on before emergencies.
When does audio recording start?+
For Pro users, emergency audio recording starts automatically when emergency mode is triggered and microphone permission is enabled.
Who can open the evidence link?+
The secure evidence web link can be shared with trusted people. It shows uploaded audio chunks and refreshes to show new uploads while emergency mode is active.
What happens after the Pro trial ends?+
The app tracks trial days left. When the trial reaches 0 days, the user must choose Free, Monthly, or Yearly.
Can paid users use the same account on many devices?+
Paid accounts are linked to email and can be active on only one device at a time to help prevent account sharing.
