How these business & teams apps were checked

Every app on this page carries a dated Trust Report. We download each build from the developer’s own release channel, verify its code signature and SHA-256 checksum, run a multi-engine malware scan, list the permissions it declares, count the tracker SDKs in the package, and record any published CVEs against the shipping version. Findings are stated with a date, never compressed into a score, and never for sale. See the full method ›
