Privacy
Short version: no account, no tracking, no analytics in the app. The scan never leaves your Mac. Only two things go online: the licence activation (and its occasional check), and a daily look for a new version that you can switch off.
What stays on your Mac
- Everything the scan finds: folder sizes, file names and paths, the causes and their sizes. They're worked out on your Mac and shown to you; they're never sent.
- Your history of fixes and the growth watch (each cause's size, saved once a day while greyspace is open, kept 90 days), saved in ~/Library/Application Support/greyspace.
- The list of processes that wrote the most to disk, read from macOS when you open it, and kept in memory only.
What leaves your Mac
| When | What is sent | To |
|---|---|---|
| You activate your licence, and now and then afterwards to check it | Your licence key and a one-way hash of this Mac's hardware ID, so the key counts one Mac once (the ID itself is never sent) | tealmac's licence server, which asks our payment provider whether the key is valid |
| Once a day, unless you switch off Check for updates in Settings | A plain request for the list of published versions; nothing about you or your Mac is added | tealmac.com |
That is the full list. greyspace has no analytics, no crash reporter that phones home, no advertising and no account.
Permissions
- Full Disk Access lets greyspace measure folders macOS keeps from apps, such as iPhone backups, Mail and Messages, and other apps' data. It reads sizes and names; it doesn't open your documents, mail or messages to read them.
- Administrator password: protected actions (deleting a local snapshot, rebuilding the Spotlight index, measuring protected folders) ask for it through the standard macOS prompt, once per action, with the command shown first. greyspace never stores it.
- Notifications (optional): only for the growth watch alert you turn on.
Buying
Checkout is run by our payment provider, Dodo Payments, the merchant of record. They handle your payment details and email address under their own privacy policy; we receive your order (email, country, amount) so we can send your licence and help you. We never see your card number.
This website
The site uses Cloudflare Web Analytics, which counts page views without cookies and without following you across sites. When you click a Buy button we count the click (the app name and the page, nothing about you), and the checkout link carries where the visit came from: the referring site's name (not the full address), the first page you opened here and any campaign tags in the link you followed. The thank-you page reads your licence key from its address in your browser and removes it from the address bar; it is sent only to our licence server to make your download link, and our server doesn't log it.
