Privacy Policy
cyclotronn PDF Viewer ("the App") is developed and published by cyclotronn. This policy explains how the App handles information when you use it — and it's short, because the App does not collect, store, or share any personal data.
The App does not collect any personal data. It does not require an account, and it never asks for your name, email address, location, or any other personally identifiable information.
The App works entirely on your device. Any PDF files you open are read and rendered locally — they are never uploaded, transmitted, or shared with us or with anyone else.
Laws such as the GDPR and CCPA give you rights over personal data a company holds about you — access, correction, deletion, and so on. Because the App collects nothing, there is no personal data associated with you for these rights to apply to.
The App does not request any special device permissions. It opens PDF files through Android's standard file picker and "Open with" system, so it never needs access to your storage, camera, microphone, contacts, or location.
The App does not use advertising networks, analytics tools, crash-reporting services, or any other third-party SDK. No data leaves the App through it, because none is collected in the first place.
The App is not directed at children under 13 and isn't designed to appeal primarily to them. Since it doesn't collect personal data from anyone, it doesn't knowingly collect personal data from children either.
Because no personal data is collected, stored, or transmitted, there is no personal data at risk of being accessed, lost, or misused through the App.
If the App's functionality ever changes in a way that affects this policy, we'll update this page and revise the effective date above.
