Privacy Policy
Last updated: October 2, 2026Tada does not collect, store, or transmit any personal data.
- No network connections. There is no networking code in the app, so neither your settings nor the notifications you send leave the Mac it is installed on.
- Local data only. Tada stores the default effect, the display language and when it was last called in this Mac’s UserDefaults (com.senkentarou.tada.app) and nowhere else.
- Notification content. The title and body passed to tada notify are used only to show a macOS notification. The notification stays in macOS Notification Center; Tada itself neither stores nor transmits it.
- No analytics, no tracking, no accounts. Tada contains no analytics SDKs, crash reporters, or third-party services, and never asks you to create an account.
- Permissions. macOS requires the notification permission only to use tada notify. Playing effects needs no permission.
This policy governs for Tada. For how information collected in connection with an app purchase or an enquiry is handled, see Senchan Company’s privacy policy.
If this policy changes, the updated version will be posted at this URL.
