Frequently asked questions
The app shows 'Searching for Bluetooth devices'
This is normal when no other JaenanTok users are nearby. You need 2+ devices within Bluetooth range (~10-100m) to communicate.
Messages aren't being delivered
Check that both devices have Bluetooth enabled and the app is open. BLE range is limited to about 10-100 meters.
How do I delete my data?
Go to Settings → Delete All Data. Or simply delete the app — all data is permanently removed.
Does this app need internet?
No. JaenanTok works entirely over Bluetooth. No server, no internet, no account needed.
Can I use this in a real emergency?
JaenanTok is designed for emergencies but does NOT guarantee delivery. Always call 112/119 when possible.
Is my data safe?
All direct messages are end-to-end encrypted. There is no server — your data never leaves your device.
