Privacy Policy

Below are my apps with short information and what user's data it can use. Every app has some more different terms & conditions.



NONE of my app use any personal user data like contacts etc and none is ever uploaded online without notifying users. First most of my apps are simple tool like apps which require internet to show ads only. Ads are delivered by Google Ad services that means only privacy policy of Google Ad services applies to my ad supported apps. Exceptions are mentioned in individual app section.


My websites:

Only use Non-Personalized ads for EEA users.

EUROPE USERS and any other user with Advertisement Consent for using personal data.

I am updating my apps to comply with Europe's EU ePrivacy Directive and the General Data Protection Regulation (GDPR) and other similar laws on ads and personal data. Apps will show a consent form asking you to give consent to use "user data" for delivering relevant ads. This section provides further details and links for understanding what "user data" is and how it is used.

My apps ONLY use AdMob (Adsense) which is Google's Mobile advertisement service. This means your consent only applies to Google AdMob, Adsense. My apps DO NOT HAVE other services which save your data outside device and that even without letting you know.

Below are links which give details on personal data. Please go through these links to know better about Ads personal data usage.

For developers, publishers and also helpful for end users.

How consent of user data for advertisement is handled?

A consent request form is shown to user 1st time app is run. Consent is taken before app connects to adnetwork. This means without getting consent app does not connects to advertisement services. Following happens when consent choice is made.

Technical description:

Here Google AdMob guides developers how to handle consent. App follows the same. Go to this section "Forward consent to the Google Mobile Ads SDK" in this page

Here Google says:

extras.putString("npa", "1");

This will cause Google to make advertisement Non Personalized. This means ads not using personal data. App only sends this value to Google. App has no other internal mechanism to manage ads and personal data. Page also describes

"If non-personalized ads are requested, the ad request URL currently includes &npa=1. However, note that this is an internal implementation detail of the Google Mobile Ads SDK and is subject to change."

It means if Google changes internal implementation then apps will again require update and technically cannot handle consent well. User's understanding regarding this matter is expected. Its out of control of developers.

List of Apps 

Strikeout apps are either temporarily disabled Or i stopped working on them permanently. NO law applies on them. If you are using them from any source other than playstore then i will not take any responsibility of it. Many websites simply collect APKs to build their catalog and provide download service. They are out of publishers control.


Donate APK

It removes Ads and unlocks locked features from many of my Android apps. It will also support development of apps. Its few KBs only and doesn't do anything other than just remaining installed. Doesn't connects to internet for ads etc. Donate or buy here :



Image Custom Size Reducer and converter


Reduce your images to custom size. For example reduce 2MB selfie to 400KB without noticeable quality loss or 50KB with some quality loss. Its an image converter also. It support size reduction with almost NOT noticeable quality loss. Very useful tool for students as well as other users.

Requires STORAGE access to save images. Internet to show ads. Google Ads policy applies.


Sacred Sound - Visualizer


This app generates cymatics, string art etc art from sounds. For example it can make rangoli arts, mandala like arts from simple human voices. Has internal generator for complex arts.
  • This software requires Microphone access to capture audio from device to render graphics on screen. The audio data is NOT USED for ANY OTHER purpose. The audio data always used inside the app and is not sent or shared to other apps or devices.
  • App requires external storage write access to just save screenshots captured by app. If disabled no screenshots can be saved or app can crash.
  • It uses Google Admob ads and therefore their privacy policy, usage terms are also applicable. Link at end of page.
  • Ads are removable through my unlock app which removes ads from my other newer apps also. It helps to keep updating the software with more dedication. Unlock app does nothing by itself other than acting as a key and therefore no privacy terms are applicable to it.


Random Graphics Generator

It only requires access to storage to save images. When internet is active Google ads are shown and the privacy terms of Google applies.

Left-Right Ear and Speaker Test


I made this app when i was repairing my Piston earphones and it also helped me when i got infection in right ear and i wanted to check by what percentage my right is hearing lesser. This small tools helps when Left-Right is not mentioned in audio listening gadgets.

Shows Google ads and so applies the ads policy.

SoundFont MIDI Player


Plays midi files with high quality instruments (SF2 files). Play old musics in high quality. Requires STORAGE access and internet to show ads. Google Ads policy applies.




Shows dominating frequency from MIC as text instead of graph. This was required when i wanted to just see most dominating frequency of sound instead dense graph. The audio is locally used for finding frequency and is NOT used for anything else. Audio is also not saved anywhere.




Allows selection of mutiple audio sources and channels to test if device supports them or not. When i tested Nokia 8.1 i found it doesn't supports STEREO recording whereas it records 3d surround sound via camera video. This tool tests the actual audio data and shows if its really MONO or STEREO. Nokia 8.1 has 2 mics and supports stereo via its proprietary recorder app. Audio is NOT SHARED outside app and not saved anywhere. Its just checks audio for MONO and STEREO and discards all audio data.
