Privacy Policy
This policy explains what data Disk Space Monitor handles on your Mac and what, if anything, leaves it.
1. Scope
This policy applies to the macOS app “Disk Space Monitor”.
2. Who is responsible
The controller responsible for processing personal data in connection with this app is:
Name: Patricia Sauer
Address: Tannenweg 3, D-16540 Hohen Neuendorf
Email: patricia@patricia-sauer.com
Website: www.patricia-sauer.com
Phone: +49 171 170 94 26
“Controller” means the person who decides how and why personal data is processed.
3. What stays on your Mac
Everything the app does happens on your Mac:
- Free-space readings of your startup disk, taken about once a minute. One reading every five minutes is kept for 30 days to show the chart and the forecast.
- Your settings, such as warning thresholds and display options.
- If you choose your home folder to find large folders: the access you granted, and the sizes of a fixed list of folders (for example caches, downloads and developer tools). The app adds up file sizes and does not open, read or change the contents of your files. Folder sizes are kept in memory only while the app is running.
This data is stored in the app’s own folder on your Mac. It is never sent to us, and we cannot see it.
4. Notifications
Warnings about low disk space are local notifications created on your Mac. They do not pass through any server. You can turn them off in System Settings at any time.
5. What leaves your Mac
Nothing. The app has no permission to connect to the internet, so macOS would block any connection attempt.
6. Purchases
Optional in-app purchases are handled entirely by Apple through the App Store. The app only learns from Apple which purchase you made, so it can unlock it. We do not receive your name, payment details or Apple account. Apple processes data as an independent controller under its own privacy policy when you download apps and make purchases, over which we have no influence.
7. What the app does not do
The app contains no advertising, no analytics or tracking SDK and no crash reporting. It does not use advertising identifiers, does not track anyone across apps or websites, does not require an account, and never asks for a name, email address or any other personal information.
8. How long data is kept
Free-space readings older than 30 days are deleted automatically. Settings and readings stay on your Mac even after you delete the app. To remove them, also delete the “Disk Space Monitor” folder in ~/Library/Containers (in Finder: Go > Go to Folder…).
9. Your rights
You have the right of access, rectification, erasure, restriction of processing and data portability, and the right to object to processing based on legitimate interest (Art. 15–21 GDPR).
In practice there is nothing for us to look up: no data about you ever reaches us. Under Art. 11 GDPR we are not required to collect extra data merely to make identification possible.
You also have the right to lodge a complaint with a data protection supervisory authority, for example the authority responsible for our place of business in Brandenburg, Germany.
10. Changes to this policy
This policy will be updated if the app changes in a way that affects it. The date below shows when it last changed.
