Sum Privacy Policy

Effective date: June 15, 2026

Sum is a local file hash checker. It lets you choose a file with Android's document picker and calculates SHA-256, MD5, file size, and saved hash checks on your device.

Files

Sum does not upload files to our servers. Selected files are read locally only for hash calculation. Sum does not edit files, scan for malware, verify official sources, or guarantee file safety.

Saved Checks

Recent hash checks may be saved locally on your device using app storage. You can clear saved checks in the app.

Advertising

Sum contains ads and uses Google Mobile Ads SDK. Google Mobile Ads SDK and Google User Messaging Platform may process data such as device identifiers, approximate location, diagnostics, app interactions, and advertising data to provide ads, measure performance, prevent fraud, and manage consent.

Children

Sum is a general utility and is not directed to children.
