Privacy policy | Andev
The short version: our tools run in your browser and never upload your files. Here's exactly what that means.
Files you open in our tools are processed locally on your device. They are never uploaded to, stored on, or seen by any server. When you close the tab, they're gone.
We don't require an account and we don't ask for personal information to use the tools. We don't sell data, because we don't collect it.
This site is served as static files from a global content delivery network. Privacy-respecting, cookieless analytics may be used to count anonymous page views and understand which tools are useful; this never includes the contents of your files. We don't use advertising trackers.
Links to our apps (Flashcards World, My Location and QZBrain) lead to separate products, each with its own privacy policy.
We aim to respect the GDPR and CCPA. Because our tools run on your device and we don't collect personal data, there is usually nothing for us to access, export, or delete — but if you have a privacy question or request, email privacy@andev.app.
Where analytics are used, they are privacy-respecting and cookieless (for example, Cloudflare Web Analytics) and never include the contents of your files.
If anything here is unclear, the principle to remember is simple: your files stay on your device.
