Privacy

Last updated November 9, 2026

OneWord is built so your learning stays yours. In short: no ads, no tracking, no selling your data, and your words and progress stay on your iPhone.

What stays on your iPhone

• Your learning: the words you've learned, your answers, progress, streak and settings are saved on your iPhone. OneWord's widget and notifications read them from there too.
• Your goal: if you tell OneWord why you're learning (for example, a trip and its date), that's saved on your iPhone only.
• Notifications are scheduled on your iPhone. Answers you give from a notification or the widget are saved on your iPhone.

We don't run servers that collect this information, and OneWord doesn't send it anywhere.

Signing in (optional)

You can use OneWord without an account. If you choose Sign in with Apple, Apple gives the app an identifier for you and, if you allow it, your name and email (or a private relay email). OneWord keeps these on your iPhone.

Microphone and speech recognition

"Say it" practice uses your microphone to hear you say a word. Recognition runs on your iPhone when the language supports it; otherwise Apple's speech recognition service processes it under Apple's privacy policy. OneWord doesn't record or keep what you say. You can skip "Say it" and turn off microphone access at any time in iOS Settings.

Reporting a problem with a word

If you tap "Report a problem", OneWord opens an email for you to send. It includes only the word and your note. You choose whether to send it, and we use it only to fix the word.

No ads, analytics or tracking

OneWord shows no ads, includes no analytics or advertising tools, and doesn't track you across apps or websites. We never sell your information.

Children

OneWord doesn't knowingly collect personal information from anyone, including children.

Deleting your information

Settings → Reset all data erases your words and progress. Deleting the app removes everything it saved on your iPhone.

Changes

If OneWord ever starts handling information differently (for example, to sync your progress between devices), we'll update this page first and change the date above.
