VAPETRACK is a free web app for tracking e-cigarette puffs. Log a puff with a single tap, and the app keeps daily counts, history, trend charts, hourly distribution, and comparisons with previous days. It runs entirely in your browser and never sends any of that to a server.
The app doesn't collect or send any personal data to a server. Specifically:
The app stores the following in your browser's localStorage (locally on your device, not on a server):
This data never leaves your browser, and the app has no access to it from anywhere else. You can remove it by clearing the site's data in your browser settings.
In the Export & Backup section you can download a summary as PDF or CSV, or a complete backup of your data as JSON. Both export and backup are generated locally in your browser from the data stored in localStorage — the app never sends them anywhere on its own. You keep and manage the backup file yourself (e.g. when switching to a new device), and can restore it the same way using the Restore from backup feature.
The app loads fonts from Google Fonts (fonts.googleapis.com). Loading the page therefore sends a standard request to Google's servers, which is common practice for most sites using custom fonts. Aside from that, the app loads no other external scripts or tracking code.
