vepu Privacy Policy
Last updated: November 10, 2026
About this policy
vepu is a paper airplane experiment notebook operated under the name vepu. This policy describes the app and its public legal and support pages. Last updated: November 10, 2026.
Your notebook stays on your device
Aircraft designs, folding instructions, hypotheses, locations you type, flight measurements, report drafts, archive selections, nickname, and badge or reference photos are stored locally on your device. A typed test location is not GPS tracking. The app does not ask for location access or upload notebook records to an application server. There is no online account or cloud synchronization service provided by vepu.
Photos and camera
You can choose a photo through the system photo picker. Only the selected image is made available to the app. If you choose to take a badge photo, camera access is requested for that action. You may deny camera access and continue with a bundled illustration or a selected photo. Images may be resized, cropped, and saved locally. The app does not record microphone audio.
Preferences and local storage
Session and display preferences are stored on your device. Notebook records use local database and application storage. Local data remains until you delete it, remove the app, or the operating system removes it. Device backups controlled by you or your operating system may include app data; their retention is governed by your device and backup settings.
Network requests for documents
Opening a legal or support page loads it over HTTPS from Cloudflare hosting. Cloudflare receives technical request information such as IP address, request time, requested URL, and browser or WebView information to deliver and protect those pages. Hosting request logs follow the hosting provider's retention practices; we do not specify a verified log retention period. These requests do not contain your flight notebook, photos, or nickname. External links, such as an email app opened at your request, follow their own policies.
Sharing and exports
You decide whether to export or share HTML, CSV, PDF, or JSON records using the system share sheet. Exports can contain your measurements, notes, report text, and embedded photos. A JSON backup can contain the whole notebook and photos. Review a file before sharing it. Copies you send to another app, person, or storage provider are controlled by that recipient and are not removed when you delete the local original.
Advertising, analytics, and purchases
The app contains no advertising, advertising identifier access, third-party analytics SDK, tracking permission request, in-app purchase, or subscription. We do not sell notebook data or use it for targeted advertising.
Your choices and deletion
You can edit or delete records in the app, change your badge and nickname, revoke camera permission in system Settings, and use the local archive deletion controls. Deleting an archive bookmark only removes that bookmark; it does not delete the underlying experiment. Uninstalling the app removes its local container, subject to operating-system backup behavior. We cannot restore notebook files that you have permanently deleted.
Young users and availability
The service is intended for users aged 13 or older. We do not knowingly request personal information from children under 13. If you believe a child has shared personal information through a support channel, contact us so it can be addressed. Intended distribution covers available App Store territories except mainland China, Hong Kong, Macao, and Taiwan, subject to the actual store listing.
Contact and changes
Contact: vepu@support.com. We may update this policy when app behavior or hosting changes. The date above identifies this version. A material change will be reflected in the published policy.
