Rattlegram

Privacy Policy

To be able to decode COFDMTV encoded text messages, Rattlegram needs access to the microphone.
Having access to the microphone is considered to be a sensitive permission and you
have the right to know what Rattlegram does with that access:
The data recorded from the microphone is only used to feed the COFDMTV decoder
and spectrum analyzer for the visualization of its frequency content.
Rattlegram uses a very small temporary buffer in volatile memory and constantly
overwrites that buffer with new data from the microphone.
The resulting text message from the COFDMTV decoder is the only data that gets stored
in persistent storage on your device.
