1. Who We Are
Explain It Easy ("the App") is developed and operated by IntrePe. If you have any questions about this policy, contact us at explainiteasyapp@gmail.com.
2. Information We Collect
2.1 Account Information
If you create a registered account, we collect the email address and password you provide through Firebase Authentication (Google LLC). This information is stored securely in Firebase and is used solely to authenticate you and maintain your account.
If you use the app as a guest (no account), we collect an anonymous device identifier generated by Firebase Installations to track your daily free-use quota. This identifier is not linked to any personal information.
2.2 Usage Data
We store the following in our own database (MySQL on Railway):
- Your Firebase UID (a pseudonymous identifier assigned by Firebase)
- Your current usage plan (registered, pro, or unlimited)
- Your daily usage count and bonus uses (reset each day)
- Session tokens used to authenticate your requests to our proxy server
We do not store the text you paste or the explanations returned.
2.3 Text You Submit
When you tap Explain, ask a follow-up question, or start a quiz, the text you entered (and, for follow-ups, the earlier explanation in that conversation) is transmitted over HTTPS to our proxy server, which forwards it to Anthropic's Claude API (Anthropic PBC, United States) to generate the response. The text is used only for this purpose and is not retained on our servers after the response is returned to your device.
Anthropic may process your text according to their own Privacy Policy. Do not submit sensitive personal information (e.g., passwords, social security numbers, financial details) through the App. A privacy notice is shown before your first request.
2.4 Photos and Camera
If you scan text with the camera or choose a photo, the text is recognised on your device (Google ML Kit). The image itself is not uploaded; only the recognised text you then choose to explain is sent, as described above. The App does not request the camera permission — photos are taken by your device's camera app.
2.4.1 Advertising Data
The App uses Google AdMob to display ads. AdMob may collect device identifiers, IP address, and usage data for ad personalisation. You can opt out of personalised ads in your device's settings (Settings → Google → Ads). If you choose to watch an optional rewarded ad for an extra explanation, the App passes Google an identifier for your account or guest installation so that Google can confirm the completed ad to our server, which then adds the bonus use. Where the law requires it (for example in the EEA and UK), the App asks for your consent before showing ads, and you can change your choice anytime under Me → Ad privacy choices. For more information see Google's Privacy Policy.
2.5 Locally Stored Data
Your explanation library (including follow-up questions and quiz scores), learning stats such as streaks and badges, and your preferences (reading level, answer style, explanation language, app language, theme, text size) are stored locally on your device. This data never leaves your device unless you explicitly use the export or share features.
3. How We Use Your Information
- Authenticate your account and maintain your session
- Enforce daily usage quotas to ensure fair access
- Serve AI-generated explanations via Anthropic's Claude
- Display relevant advertisements via Google AdMob
- Diagnose technical issues via server-side logs (logs do not include your input text)
4. Data Sharing
We share data only with the following third-party services as necessary to operate the App:
- Google Firebase — authentication and anonymous device identification
- Anthropic — AI explanation generation (input text, reading-level preference)
- Google AdMob — in-app advertising
- Railway — cloud hosting provider for our proxy server and database
We do not sell, rent, or trade your personal information to any third parties.
5. Data Retention
- Account and quota data is retained as long as your account is active.
- Anonymous device records are retained to enforce daily quotas; they contain no personal information.
- Session tokens expire after 30 days (registered) or 1 day (anonymous).
- Server request logs are retained for up to 30 days for debugging purposes.
6. Your Rights & Data Deletion
You have the right to request deletion of any personal data we hold about you. To submit a deletion request, visit our Data Deletion Request page. We will process all requests within 30 days.
In the App: signed-in users can permanently delete their account under Me → Account → Delete account. This removes your sign-in account (Firebase), your records in our database and your active sessions, and clears the data stored on that device.
7. Children's Privacy
Explain It Easy is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us at explainiteasyapp@gmail.com and we will promptly delete it.
8. Security
All communications between the App and our servers use HTTPS. Passwords are managed entirely by Firebase Authentication and are never stored or visible to us. We apply reasonable technical and organisational measures to protect your data; however, no system is 100% secure.
9. Changes to This Policy
We may update this Privacy Policy from time to time. We will update the "Last updated" date at the top of this page. Your continued use of the App after changes are posted constitutes your acceptance of the revised policy.
