YouWrite ("the App") is an IELTS Writing practice application developed by PrincipiaForge ("we," "us," or "our"). This policy explains what data the App handles, how third-party services are used, and your rights regarding your information. It applies to the App on all platforms where it is offered, including Google Play and the Apple App Store. The App is offline-first and requires no account, sign-in, or sign-up: your writing stays on your device, and we operate no servers that store it.
1. Data We Collect
We do not collect, store, or transmit your essays, practice content, or study data to our own servers — we operate none. There is no account or profile to create, and we hold no information that identifies you. All of your essays, review history, decks, progress, in-app statistics, and preferences are stored locally on your device. The only data that leaves your device is the limited information processed by the third-party services described below, and anything you yourself choose to share with an external AI tool (see Section 3).
2. Third-Party Services
The App integrates the following third-party services, which may process limited data according to their own privacy policies. Firebase Crashlytics and Firebase Analytics (Sections 2.1 and 2.2) are used in the Android app only; the iOS app does not include Firebase. RevenueCat (Section 2.3) is used on both platforms.
2.1 Firebase Crashlytics (Google)
Used to collect anonymous crash reports so we can identify and fix bugs. Crashlytics automatically collects device information (such as model and OS version), app state at the time of a crash, and stack traces. It does not collect your essays or other writing, and it does not identify you personally.
2.2 Firebase Analytics (Google)
Used to understand which features help learners and how the App is used in aggregate, so we can improve it. Analytics collects app-interaction events and device or other identifiers (such as a non-permanent app instance ID). It does not collect your essays or other writing. Aggregate usage data helps us decide what to build next.
2.3 RevenueCat
Used to manage in-app Pro subscriptions. RevenueCat processes purchase transactions made through Google Play or the Apple App Store and may collect an anonymous app user identifier and your purchase history to determine your subscription status. No personal information beyond what the store provides for a purchase is shared, and no essays or writing are shared.
We only use third-party services that are bound by their own privacy and data-protection commitments, which provide the same or equal protection of your data as described in this policy.
3. Your Essays and the "Bring Your Own AI" Handoff
The App contains no AI and never sends your essays anywhere on its own. When you use the grading handoff, the App copies your essay text so that you can paste it into the external AI tool of your choice (such as ChatGPT, Claude, or Gemini). At that point you are sharing that text directly with a third party that we neither control nor operate. Any information you provide to that AI tool is governed by that provider's privacy policy and terms, not ours. We recommend reviewing their policies and avoiding sharing sensitive personal information in your practice essays.
4. Data Storage
All App data is stored locally on your device using an on-device database. You can export your data to a file and import it again — for example, to move to a new device — and those files are created and stored wherever you choose. We never receive a copy of this data.
5. Data Sharing
We do not sell, trade, or rent your personal data. We do not share your essays or study data with any third party. The only data transfers that occur are (a) the limited, mostly anonymous data sent to the third-party services in Section 2, and (b) any content you yourself choose to share with an external AI tool as described in Section 3.
6. Data Retention
Data stored locally on your device is kept until you delete it or uninstall the App. Data processed by the third-party services in Section 2 is retained by those services according to their own retention policies (for example, Firebase Crashlytics keeps crash reports for 90 days) and is then deleted or anonymized.
7. Your Choices and Deleting Your Data
You are always in control of your data:
- Local data — Use the App's reset option in Settings to erase your essays, decks, and progress, or simply uninstall the App to remove all local data from your device.
- Data held by us — None. Because the App has no accounts and we operate no servers, we hold no copy of your essays, study data, or any profile about you.
- Third-party data — The limited data processed by the services in Section 2 is not linked to your name or email, and it expires under their retention policies (Section 6). If you have questions about it or would like us to request its deletion, email us at [email protected] with the subject "Data deletion". We will respond within 30 days.
- Withdrawing consent — You can withdraw your consent to data collection at any time by uninstalling the App, which stops all further collection. You can then request deletion of data already collected as described above.
8. Children's Privacy
The App is intended for IELTS candidates, typically teenagers and adults preparing for the exam. It is not directed at children under 13, and we do not knowingly collect any data from children under 13. Because the App has no accounts and stores everything on the device, it does not collect names, email addresses, or other contact details from anyone, including children.
9. Changes to This Policy
We may update this policy from time to time. Any changes will be reflected on this page with an updated effective date. Continued use of the App after changes constitutes acceptance of the revised policy.
