backup and portability

Your data

Entries are stored on this device in browser storage for this website. The server serves the app files but does not receive your entries. Export a backup periodically so clearing Chrome data or losing the phone cannot erase the only copy.

privacy

How storage works

Cycle Signal has no account, analytics, advertising, remote database, or data-upload API. The hosted files and offline cache contain only application code; your entries remain in Chrome storage on this device unless you explicitly export or share them. Anyone who can open your unlocked phone and this app can read the entries.
