Privacy Policy
Last updated: November 10, 2026
In short: SiftClean scans and cleans your disk entirely on your computer. Your files, their names and their paths are never sent anywhere. If you allow it, the app shares a few anonymous counts that help us understand how it is used.
Data that stays on your computer
Everything SiftClean needs to show you your disk – folder names, file sizes, modification dates and Smart Scan results – is processed locally and kept only in memory while the app is running. Your settings are stored in a small file in your user profile.
Anonymous statistics
When “Share analytics” is on, SiftClean sends the following information:
| Data | Why |
|---|---|
| A random installation ID created on first launch | To count how many installations use the app, without knowing who you are |
| The type of event: app opened, scan finished or items deleted | To understand which features are used |
| The amount of space freed and the number of items deleted | To show how much space SiftClean saves in total |
| The number of files in a finished scan | To improve scanning speed on large disks |
| Operating system, app version and app language | To decide where to focus fixes and translations |
We never collect file or folder names, paths, file contents, your name, e-mail address or your account details. We do not store IP addresses.
Your choice
You can switch statistics on or off at any time in Settings → Share analytics, or during the first-run setup. When it is off, the app sends nothing.
Where the data is stored
Statistics are received by a Google Apps Script service and stored in a Google spreadsheet operated by us. Google acts as our hosting provider and processes the data under its own terms. Because the data is anonymous, we can’t link it to you or to a specific device.
This website
The website does not use cookies or third-party trackers. When you click a download button, we count the click together with the chosen platform. Nothing else is recorded.
Retention
Anonymous statistics are kept for as long as they are useful for improving SiftClean and may be deleted at any time.
Changes
If this policy changes, we will update the date at the top of this page. Significant changes will be announced in the app.
