Privacy Policy
1. Information stored on your device
To work, the app saves the following on your phone only:
- your settings (theme, units, view mode and similar choices);
- your favorite elements and the notes you write;
- your quiz and flashcard progress, and your study streak;
- a flag that remembers you have seen the introduction.
This information is not sent to us or to anyone else by the app. You can remove it at any time (see section 7).
2. Information we collect
We do not collect personal information through the app. There is no sign-up or login. The app does not include advertising or analytics tools.
3. Sending a suggestion or sharing
- Send a suggestion: the app opens your own email app with a message addressed to stardustsupport@gmail.com. Nothing is sent from the app itself. The message is sent only if you send the email. If you switch on “Include app and Android version”, those details appear in the email text. We use emails only to reply and to improve the app. Please do not include personal details.
- Share an element card: the app creates a temporary image on your device and hands it to the sharing menu. You choose which app receives it. We do not receive it.
4. Links to other websites
Some screens can open web pages, such as the data sources, in your browser. Those websites have their own privacy practices, which we do not control.
5. Information from Google Play
If you install the app from Google Play, Google may collect information about your installation and device according to Google’s own policies. Google may give us summaries, such as the number of installs, ratings and crash reports, that do not identify you.
6. Children
Stardust is a study aid for students. It does not ask for personal information and has no accounts, so it does not knowingly collect personal information from anyone, including children. If you are a parent or guardian and have a question, please contact us.
7. Your choices
To delete the information stored by the app, open your phone’s Settings, go to Apps, choose Stardust, then Storage, and select “Clear data”. Uninstalling the app also removes it. Because we do not hold your data, there is nothing for us to delete on our side, except any emails you have sent us. You can ask us to delete those.
8. Changes to this policy
If the app changes in a way that affects your privacy, for example if advertising is added, we will update this page and the effective date, and we will describe the change in the app and on its store page before it takes effect.
