About vepu
vepu is a local notebook for paper airplane designs, folding steps, version comparisons, measured flights, and reports. No online account is required. To begin, open the app and choose Enter the laboratory.
Using your notebook
Use Lab to view designs, New fold to create folding instructions and an experiment, Flight log to find batches, Archives for saved bookmarks, and Passport to edit your local researcher badge and open settings. Record distance and airtime manually. Failed or excluded trials do not enter the valid-measurement comparisons.
Photos and permissions
Use Choose from Photos to select a single image. Move and zoom the square crop to frame a badge photo, then choose Use Photo. Camera availability depends on your device and permissions. If camera access was denied, enable it in the device Settings app or use a bundled illustration. Flight notes and measurement entry do not require camera access.
Exporting and protecting data
Export formats include HTML, CSV, PDF, and JSON. JSON backups may include your whole notebook and embedded photos. Store exported files in a location you control and review personal content before sharing. Backup import is not included in this version. Keep the original app data until you have verified that an export is complete.
Troubleshooting
If a save or export does not finish, wait for its message and retry after the current operation ends. Ensure that your device has available storage. If a hosted policy page cannot load, check your connection and use Retry. Avoid uninstalling the app as a troubleshooting step unless you have preserved the data you need. Permanently deleted local records cannot be recovered by vepu support.
Privacy and purchases
Notebook records and photos stay on your device unless you export or share them. Opening hosted policy pages makes ordinary HTTPS requests to Cloudflare. There are no in-app purchases, subscriptions, advertising, or third-party analytics SDKs in this version. Read the Privacy Policy for further detail.
