MathVellum (“the app”) is developed by Youssef Charif Hamidi. This policy describes what the app does and does not do with your information.
MathVellum does not collect, transmit, or share any personal information. The app runs entirely on your device. It has no servers, no analytics, no advertising, and no third-party tracking.
The app stores the following information locally on your device so that your work persists between sessions:
This data never leaves your device. It is not sent to us or to any third party. Uninstalling the app removes this data.
When you use the export feature, the app generates a PDF file and saves it to your device’s public Downloads folder. The app does not retain a copy of these files and does not transmit them anywhere. What you do with the exported file is entirely under your control.
The app does not make any network requests. It works fully offline.
The app is suitable for users of all ages. Because no data is collected, there is no special handling for children’s data — there is simply no data.
None. The app does not integrate any analytics, crash reporting, advertising, or social-media SDKs.
If this policy changes, the new version will be published at the same URL with an updated “Last updated” date.
