Security & authenticity
Security rating: Trusted
Signing certificate
Certificate issued to “chaimob”Not the developer's name (“Arvind Kumar”). Names in certificates can't be verified, so this alone proves nothing.

Scans and ratings come from the source store; the certificate comparisons are AAPKs's own, made from the files' published signatures. AAPKs doesn't scan files itself — compare the MD5 and signer after downloading.
Permissions (4)
Data Structure requests 4 permissions, none of them sensitive.

Can I install this APK over the version I already have?
Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.
Is the Data Structure APK safe?
No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is 2579501b3dfb5b6409f6d047e097ea0f.
