Privacy
Mister Plimsoll runs entirely on your Mac. It collects no analytics, no telemetry, and no usage statistics. Nothing is sent to any server I control.
Your configuration — the volumes you choose to monitor, your thresholds, your alert preferences — is stored in macOS user defaults on your Mac alone.
Credentials, such as the SMTP password you give Mister Plimsoll for sending email alerts, are stored in your macOS Keychain, encrypted at the operating-system level. They never leave your Mac except to authenticate with the third-party service you’ve chosen (your email provider’s SMTP server).
If you click Leave a tip, you’re redirected to Stripe’s hosted checkout page. Stripe collects payment information per Stripe’s own privacy policy.
The misterplimsoll.app website may keep standard server logs (IP address, timestamp, requested page, user agent) for operational and security purposes. These are not used for analytics, advertising, or any other purpose, and they aren’t shared with anyone. They are typically deleted within 60 days.
Beta software warning
Mister Plimsoll is in beta. That means it may have bugs that cause it to fail to alert you when a drive crosses your threshold, fire false alerts, fail to send email or iMessage, or behave in other unexpected ways.
Please don’t rely on it as your sole protection against running out of disk space, particularly on production machines, servers, or systems where running out of room would have serious consequences. Treat its alerts as one signal among several.
Liability
Mister Plimsoll is provided as-is, without warranty of any kind, express or implied. To the fullest extent permitted by law, Glenn Fleishman is not liable for any direct, indirect, incidental, consequential, or other damages arising from use or misuse of the software, including (but not limited to) data loss, missed alerts, hardware damage, downtime, or business interruption.
The software is free. By using it, you accept these terms. If you don’t agree, please don’t install or run it.
