This policy covers Terminal, Insomnia, Leaflet, Clocks, and NFC Lab. No account is required to use any of them. We do not collect, store, or transmit personal data, and we do not know how many people use our apps, how often, or what they do with them.
The apps contain no analytics, crash reporting, advertising SDKs, or tracking of any kind. None of them are designed for or directed at children, and none collect personal information from anyone, including children under 13.
Data. Server credentials and SSH keys are stored locally on your device and never leave it except as part of direct SSH connections to servers you configure.
Network. The app connects only to SSH servers that you explicitly add and connect to. All network traffic goes directly from your device to your server. No data is routed through Silly Siren Studios servers or any third-party infrastructure.
In-app purchases. Purchase transactions are handled entirely by Apple via StoreKit. Silly Siren Studios does not receive or store your payment information. We have no visibility into who purchases Pro beyond what Apple provides in aggregate App Store reporting.
Network. Insomnia never connects to the internet. It has no servers, no accounts, and nothing to sync. Everything it does happens entirely on your computer, using the system's own power management APIs.
Data. Insomnia stores your preferences on your computer only: your settings (such as timer, battery and hotkey options), the apps you choose for auto-activate, and whether you've set it to launch at login, which the system itself manages via SMAppService. These stay inside the app's sandbox container, are never transmitted, and can be removed by deleting the app and its data folders in ~/Library/Containers. The launch-at-login registration is managed by the system and may remain listed in your computer's login settings until you remove it there. Nothing is measured, logged, or sent about how you use the app.
Deleting your data. Silly Siren Studios holds no data about you from Insomnia. There is no account to close and nothing for us to delete. To remove what Insomnia stores on your computer, delete the app and its data folder in ~/Library/Containers (com.sillysirenstudios.insomnia).
Network. Leaflet has no servers, no accounts, no analytics, and no update checks, and it never sends your files or any information about you or your use of the app anywhere. By default it never contacts the internet when you open a document: images that a document points at over the internet are not loaded. If you choose to load them, for one document or for all of them, your Mac requests those images directly from whoever hosts them, the way a web browser would, and nothing goes through Silly Siren Studios. That choice is off until you turn it on. The app also holds macOS's standard network-client entitlement, because macOS requires it for the built-in web views that render Mermaid diagrams and math inside a sandboxed app. All of the diagram and math code is bundled inside Leaflet itself.
Data. Leaflet only reads the specific Markdown, plain-text and data files (shown as rendered Markdown or in a plain monospace view) and folders you choose to open, and never writes to or modifies them. The only file it can write is a PDF that you choose to save from the print panel. It stores your display preferences (appearance, text size and window size), the list of folders you had open, so they reopen when you relaunch the app, and whether you chose to load remote images for all documents, on your Mac only. They stay inside the app's sandbox container, are never transmitted, and can be removed by deleting the app and its data folders in ~/Library/Containers. Nothing is measured, logged, or sent about how you use the app.
Deleting your data. Silly Siren Studios holds no data about you from Leaflet. There is no account to close and nothing for us to delete. To remove what Leaflet stores on your Mac, delete the app and its data folders in ~/Library/Containers (com.sillysirenstudios.leaflet and com.sillysirenstudios.leaflet.quicklook).
Network. Clocks has no accounts, no analytics, and no network access at all: the app holds no network entitlement, so it cannot connect to the internet. Nothing leaves your Mac.
Data. Clocks stores your preferences on your Mac only: your list of cities and any custom labels, which city shows in the menu bar, your display options (time format, seconds, date, clock style and whether a location shows in the menu bar), the height of the clock list, and whether you've set it to launch at login, which macOS itself manages as a Login Item via SMAppService. These stay inside the app's sandbox and its shared App Group container (shared only between the app and its own widget), are never transmitted, and can be removed by deleting the app and its data folders in ~/Library (Containers and Group Containers). Nothing is measured, logged, or sent about how you use the app.
Network. NFC Lab has no servers, no accounts, no analytics, and no network access at all: the app holds no network entitlement, so it cannot connect to the internet. Nothing it reads from a tag or stores on your device is sent to Silly Siren Studios or anyone else.
Data. NFC Lab reads and writes NFC tags only when you hold a tag to your phone and start a scan or a write. It stores your tag library (saved scans and templates, with their folders), imported CSV data, Lab snapshots and notebook notes, and your display settings on your device only, inside the app's sandbox. They are never transmitted. If you export a JSON file, a CSV file, a snapshot, a report, a console transcript or a memory dump, or share one from the app, it goes where you choose to send it using the system share sheet, and Silly Siren Studios does not receive it. The automation actions (Scan NFC Tag, Read URL from NFC Tag and the three Write actions) pass data only between your own automations on your device. Nothing is measured, logged, or sent about how you use the app.
Tags. Writing to a tag changes that tag. Locking a tag read-only is permanent, and so are some Lab settings (for example a password attempt limit or a configuration lock). Information on a tag can be read by anyone with an NFC reader, so do not write secrets to a tag you leave in a public place.
Deleting your data. Silly Siren Studios holds no data about you from NFC Lab. There is no account to close and nothing for us to delete. To remove what NFC Lab stores on your device, delete the app; the system removes the app's data with it. Anything you exported or shared is a file you control.
If this policy changes, the updated version will be posted at this URL with a new "Last updated" date.
