We maintain an officially verified app-ads.txt file ensuring brand protection and transparent ad serving.
Quick answers on data privacy, permissions, and application support.
No. DecibelPro computes sound pressure levels (dBA) in real time entirely on your device using transient memory buffers. Audio samples are never written to disk, never recorded, and never uploaded to any remote server or cloud system.
Our applications are designed with privacy-first principles and do not require user account registration. As such, we do not store personal account profiles. If you have contacted support or submitted telemetry and want all associated correspondence permanently deleted, email rajasaad707@gmail.com with the subject "Data Deletion Request" and your request will be honored within 48 hours.
Yes. Core features across our apps—including DecibelPro's sound meter and acoustic tone generator, Emoji Riddle's rebus puzzle stages, and our sorting games—are fully functional offline without an active internet connection.
Yes. Apps designed for children (such as TinySteps and Numbers 123) strictly adhere to COPPA (Children's Online Privacy Protection Act) and Google Play Families Policy guidelines. We never collect personal identifiers from children, do not serve interest-based ads, and protect sensitive parent settings behind a parental gate.
