DeltaDisk is built so that information about your disks never leaves your Mac.
What the app sends
Two things, both to mossbit.app:
- An update check, once a day. It sends the app version and the macOS version. Nothing else — system profiling is switched off in the app.
- A download of the revoked-key list, once a day. This is a plain file request; no license key and no personal data are sent.
There is no analytics, no crash reporting and no account. Folder names, file names and sizes are never transmitted.
What the app stores on your Mac
- Trial start date and, after purchase, your license key (in the macOS Keychain and in the app's settings file).
- Your settings and the list of folders you watch.
- The daily size history used to show what changed.
What we keep when you buy
Your name, your email address and the license ID, stored in Cloudflare KV. We use them to issue your key, to show it again when you ask, and to revoke it if a purchase is refunded.
We never see or store your card details. Payment is processed by Stripe — see the Stripe Privacy Policy.
Server logs
Our site runs on Cloudflare, which keeps standard request logs (including IP addresses) for a short period.
Your rights
Email support@mossbit.app to ask what we hold about you or to have it deleted. Purchase data held by Link can also be deleted by contacting Link.
Cookies
mossbit.app sets no cookies. Stripe Checkout runs on Stripe's own domain under their policy.
