Amino Sprint

Privacy Policy

Your practice stays on your device. The app does not collect personal data or track you.

Who this policy covers

This policy describes Amino Sprint and this website, provided by Eilon Krauthammer. For privacy questions, contact eilonkrauthammer@gmail.com. Effective September 20, 2026.

No app data collection

The app has no account system, advertising, tracking, analytics service, or developer-operated backend. We do not receive, sell, or use your in-app activity for advertising. The current app has no purchases or subscriptions.

What stays on your device

Amino Sprint stores quiz results, confidence choices, review dates, session history, personal memory cues, and Mix-up Lab progress in the app’s local storage. Appearance and haptics preferences are also stored locally. These records support practice and scheduled review. They are not transmitted to the developer.

Permissions and external links

The app does not request access to your microphone, camera, location, contacts, or photos. It has no advertising, analytics, or third-party crash-reporting service. If you open a reference link, the destination website and your browser handle that visit under their own privacy practices.

Your controls and deletion

You can reset learning progress in the app’s settings. A reset preserves appearance and haptics preferences. A recovery copy of an unreadable progress file may remain locally after a reset. Deleting the app, rather than offloading it, removes its local app data. Device backups may retain copies until you manage or delete those backups. There is no developer-held account or remote learning database to delete.

Device backups and Apple services

Your operating system may include app files in device backups, depending on your settings. This is separate from app-provided cloud sync; the app does not offer cloud sync. Apple manages App Store transactions, system diagnostics, and any information you choose to share with Apple under Apple’s privacy policy.

This website

This website is hosted with OpenAI Sites. Requests to load it necessarily involve technical information such as your IP address, browser information, requested page, and request time. Hosting providers may process this information to deliver and secure the site under their own practices; see OpenAI’s privacy policy. We have added no advertising pixels, analytics scripts, contact forms, or tracking cookies. App data is not sent to this website.

If you contact support

If you email us, we receive your email address and whatever you include. We use that information to answer and resolve your request. Our email provider processes the message to deliver and store it. Please avoid sending sensitive information or recordings unless needed for your request. Support correspondence is retained only as needed for support, security, or legal obligations. You can request deletion by email, subject to any retention required by law.

Children and privacy rights

The app does not knowingly collect children’s personal information. A parent or guardian can contact us about information a child may have sent to support. Depending on applicable law, you may have rights to access, correct, delete, restrict, or object to processing of information you provide to us, and to complain to a data protection authority. Email us to exercise applicable rights. We cannot retrieve data that exists only on your device.

Changes

We will update this page and its effective date if our practices change. Material changes will be described here. Contact eilonkrauthammer@gmail.com with questions.
