Oto Reactor · Updated 13 October 2026

Summary

Oto Reactor does not collect personal data. The app has no accounts, no analytics and no advertising, and it does not send any data to our servers.

Data on your device

Your vocabulary, review progress, goals, reminder time and settings are stored only on your device. They are included in your device backups (for example, iCloud Backup) under Apple’s terms. Deleting the app deletes this data. Reminders are scheduled by iOS on your device.

Translation

Subtitles and words are translated by iOS on your device. The first time you use a language, iOS may download it from Apple. The text you translate is not sent to us.

YouTube

Oto Reactor uses YouTube API Services. Videos are played by the YouTube embedded player, and video details, subtitles and thumbnails are loaded directly from YouTube. When you watch a video or paste a link, your device connects to YouTube, which may collect information such as your IP address, device details and data stored in cookies or similar technologies, as described in the Google Privacy Policy. We do not receive this information. By using Oto Reactor you also agree to the YouTube Terms of Service.

Email

If you write to us, we receive your email address and message and use them only to reply.

Children

Oto Reactor is not directed at children under 13 and does not collect information from them.

This website

This website does not use cookies, analytics or trackers. It is hosted on Cloudflare Pages; Cloudflare may process technical data such as IP addresses to deliver and protect the site.

Changes

If a future version adds features that handle personal data, such as optional sign-in or backup, we will update this policy before that version is released.
