Privacy Hub

One policy per app

Each Kaifuz Studio app is built for a clear purpose, so each has its own dedicated privacy policy. Select your app below.

• KaiCleaner Privacy Policy Media stays strictly on your device — nothing is uploaded, and nothing is deleted automatically.
• KaiCam Privacy Policy Camera, Bluetooth, and local-network access are used solely to control your connected camera.
• KaiPlay Privacy Policy (Formerly BabyVocab) Offline-first, child-safe, and parent-gated vocabulary games.
• KaiReader Privacy Policy Vocabulary, reading history, and progress stay local; sentence translation is optional.

Speech Timer

Speech Timer runs entirely in your browser — your agenda, notes, and settings never leave your device unless you choose to share them. Pressing "Copy share link" is optional and uploads that agenda's text (names and notes) to our server so it can be opened from the short link; it is deleted automatically 30 days after its last update. Turning on "Sync this meeting" additionally shares the current position in the meeting (which speaker, how much time is left, running or paused) with everyone holding the link, for as long as the meeting is running — it stops the moment sync is turned off or the meeting ends. If the server can't be reached, Copy falls back automatically to a long link that shares without uploading anything, by encoding the agenda into the link itself. Speech Timer has no account, no cookies, and no analytics.
