MemoryGuardian vs PilferShush Jammer
Side-by-side comparison of two open source alternatives
MemoryGuardian
A Small App for Enhanced Privacy & SecurityMemory Guardian is a lightweight Android app that enhances user privacy and security by automatically clearing the clipboard at set intervals. This helps protect sensitive information, like passwords, from potential leaks to other applications.Key Features:Automatic Clearing: Set customizable intervals for automatic clipboard clearing.Manual Clearing: Use the "Clear" button for immediate action.Clipboard Editing: Edit clipboard content directly within the app for quick adjustments.Notifications: Get notified when the clipboard is cleared.Dark Mode: Switch between light and dark themes for a personalized experience.Tiny: The app is small in size and does not consume much storage space.No Permissions: Memory Guardian does not require any permissions to function, ensuring user privacy.No Ads: Enjoy an ad-free experience with no interruptions.Minimalistic: Experience a clean and clutter-free interface for a distraction-free user experience.Open Source: Contribute to the project and help improve the app for everyone.
PilferShush Jammer
Features a passive jammer technique that engages the microphone thereby blocking other apps from using it. But does NOT listen to or record any of the audio from the microphone. It uses 0% CPU and no noticeable battery use. However is not intended to be left on permanently due to the variety of triggers that can cause audio_focus_state changes (VOIP etc). Also features an active jammer that emits tones constrained to the NUHF range of 18 kHz to 24 kHz range. User determined carrier frequency and drift limits with rate for random tone emissions depending on the device capabilities. For instance 20000 Hz carrier, drift limit 1000 Hz and rate slow - will output random frequency between 19 kHz and 21 kHz approximately every second. Audible artifacts are present during the NUHF tones but this may be changed in a future release. Experimental white noise output may not be very effective at blocking and is a somewhat annoying sound. The device speaker output may not have enough amplitude to block unwanted NUHF signals - testing will determine. * Manual start * Notification post when running * Auto stop and restart when telephony interrupts * Currently relies on audio_focus_state changes for auto-switching * Active jammer
