Privacy Policy

Effective date: November 10, 2026 · Last updated: November 10, 2026

Yumijam LLC ("we", "us") publishes Lingoonie, an Android app for learning Spanish, French and Italian. This policy explains what the app does with information.

1. Information stored on your phone

The app saves these in its private storage on your phone:

• Your learning progress, review schedule, streak and favorites.
• Your settings (for example voice, speed, light or dark theme, your last screen).
• Which paid plans you own, as reported by Google Play.
• Error reports waiting to be sent, if you were offline.
• Texts and files you add to the Reader ("My Texts"), and the translations made from them.

We cannot see this information. You can delete all of it by clearing the app's storage in your phone settings or by uninstalling the app.

Phone backup. Android may back up your saved progress to your Google Account and may copy it to a new phone, depending on your phone's backup settings. Files you added to the Reader are left out of the cloud backup but can move with a phone-to-phone transfer. That backup is run by Google under Google's Privacy Policy. You control it in your phone's backup settings.

2. Purchases

Paid plans are annual subscriptions bought through Google Play. Google processes the payment. The app asks Google Play which plans you own and unlocks content to match. We never receive your card or bank details. Google gives us sales and subscription reports through Google Play Console (for example order and product details) under Google's terms. You can cancel or change a subscription in Google Play, and the app has a button that opens Google Play's subscription page.

3. "Report an error" and "Contact support"

Cards in the app have a flag button. If you tap it and press Send, the app sends us:

• The app version, the language, the card ID and the screen name.
• The text shown on that card.
• The type of problem you picked and the optional note you typed.
• The time you sent it.

We do not collect your name, phone number or device ID with the report. Please do not put personal information in the note.

Contact support. In Settings, "Contact support" lets you send us a message from the app. It sends the topic you picked, your message, the app version, the language and the time. You may also type an email address only if you want a reply; it is optional, and we use it only to answer you. It travels the same way as a report (below).

The report is sent securely (HTTPS) to a form on this website, which is hosted by Netlify. Netlify stores the submission and emails it to us. Like any web host, Netlify may see your IP address in its server logs. If you are offline, the app keeps up to 50 reports on your phone and sends them later.

We use reports only to fix mistakes in the app. We keep them for 12 months after they are received, then delete them. To have a report deleted sooner, email support@lingoonie.com.

4. Reader translation

The Reader lets you add your own text and shows a translation. In the Android app, translation and language detection are done on your phone, using Google's ML Kit. The text you translate and its translation never leave your phone and are not sent to us or to anyone else. The first time you use a language, the app downloads that language's translation file (about 30 MB per language) from Google. That download is a network request to Google, so Google may see that a download was requested (for example your IP address), but not your text. After that, translation works without the internet. ML Kit also sends Google some diagnostic data; see section 6.

5. Pronunciation audio

The app speaks words and sentences with your phone's built-in text-to-speech. Some phone voices may use the internet. That is controlled by your phone's speech provider, under its own policy.

6. Other connections and service providers

The app uses the internet for: sending a report you chose to send, Google Play purchases and subscription checks, update checks through Google Play, downloading a translation language file, ML Kit diagnostics (below), and opening links you tap. The home-screen widget shows words from the data already on your phone and does not use the internet.

Google ML Kit. The translation and language-detection features use Google's ML Kit software. ML Kit sends Google diagnostic and usage data: device information (manufacturer, model, operating system version), the app name and version, performance measurements, error codes, the languages set for translation, and an installation identifier. According to Google, this data is encrypted in transit, is used for diagnostics and usage analytics, and is not shared with third parties. We do not receive this data. See Google's ML Kit disclosure and Google's Privacy Policy.

7. Permissions

The app declares only these Android permissions: Internet, Network state (to know if you are online), Keep awake (so the screen can stay on while you study, only if you turn on that setting), and Google Play Billing (for purchases).

8. What we do not do

We do not sell your information. We do not show ads. We do not track you across apps or websites. We do not build a profile of you. Lingoonie does not include advertising, tracking or analytics tools of its own. The only analytics-type data comes from Google's ML Kit, described in section 6.

9. This website

lingoonie.com sets no cookies and has no analytics or advertising tools of its own. It is hosted by Netlify, which processes basic connection data (such as IP addresses) to deliver and protect the site; see Netlify's Privacy Policy.

10. Children

Lingoonie is not directed to children under 13, and we do not knowingly collect information from children under 13. If you believe a child has sent us information, email us and we will delete it.

11. Your choices

• Delete your on-phone data: clear the app's storage or uninstall.
• Delete a report you sent: email support@lingoonie.com.
• Stop backups: change your phone's backup settings.
• Cancel a subscription: use Google Play.

If you live where the law gives you rights over your information (for example access, correction or deletion), email support@lingoonie.com and we will respond within the time the law requires.

12. Security

Reports are sent over HTTPS. Your saved progress is kept in the app's private storage on your phone. No method is perfectly secure.

13. Changes

If we change how the app handles information, we will update this policy and the "Last updated" date. If a change is significant, we will say so in the app or on this website.
