SentenceRay ("the app") is made by StarNova. This policy explains what the app collects, why, and what your choices are. It is written to be read, not to be survived.
| Data | Why |
|---|---|
| The text you submit — the sentence you paste, share into the app, or ask a question about | To produce the X-Ray (structure, backbone, meaning, vocabulary, quick check) and to answer your "Ask about this" questions. The text and its analysis are stored so your Recent and Saved lists work. |
| An anonymous visitor identifier — a random ID created on first launch, plus a device fingerprint value used only to recognise a reinstall as the same visitor | To count your free daily X-Rays and AI questions, to keep your history, and to attach a Pro subscription to your install. It is not linked to your name, email, Apple ID or phone number. |
| Preferences — your English level and your explanation language | To pitch explanations at the right level and in the language you chose. |
| Usage events — for example: the app was opened, a sentence was X-Rayed, the paywall was shown, a purchase completed | To understand which parts of the app help and which do not. The text of your sentences is never included in analytics events. |
| Purchase state — whether a subscription is active, its product and renewal date | To unlock Pro and to restore it on a new device. |
SentenceRay does not ask for and does not use your microphone, camera, photos, contacts, location, calendar, or health data. It does not track you across other apps or websites, and it shows no advertising.
We do not sell personal data and we do not share it with anyone else, except where the law requires it.
Submitted sentences and their analyses are kept while your install exists so that your history works; on the Free plan only your most recent five are shown. Analytics events are retained by Google for up to 14 months. If you ask us to delete your data, we delete the visitor record, its submissions and its analyses within 30 days.
SentenceRay is intended for a general audience and is not directed at children under 13. We do not knowingly collect data from them. If you believe a child has used the app and you would like their data removed, contact us and we will remove it.
Our servers and our providers are located outside your country in some cases. Where data is transferred out of the EEA or the UK, it is done under the European Commission's Standard Contractual Clauses or an equivalent safeguard.
If this policy changes in a way that matters, we will update the date at the top and, where the change is significant, note it in the app.
