Privacy Policy
Chartless is a Google Chrome extension that listens to the audio of the browser
tab you choose and displays the chords it detects — the current chord, the song's
key, recent chords, and optional fingering diagrams — as an overlay on that tab.
Short version: Chartless does not collect any personal
data. Tab audio is analyzed entirely inside your browser, in real time, and is
never recorded, stored, or transmitted anywhere. There are no servers, no
accounts, and no analytics.
What Chartless processes, and where
- Tab audio — captured only after you press Start in the
extension popup, and only for that tab. The audio stream is analyzed in
memory (pitch and rhythm features) and discarded immediately. No audio is
ever written to disk, recorded, or sent over the network. Pressing
Stop (or closing the tab) ends the capture.
- Detection results — the chords, key, tempo, and chord-progression
patterns detected for a song may be cached locally in your browser's
extension storage so the next play of the same song locks in faster. This
data never leaves your device.
- Your settings — mode, presets, instrument choice, overlay position.
Stored locally in your browser's extension storage only.
What Chartless does not do
- No audio recording, storage, or transmission — ever.
- No collection of personal information of any kind.
- No analytics, telemetry, tracking pixels, or third-party services.
- No accounts, sign-ins, or server communication. The extension makes no
network requests.
- No reading of page content. The overlay is drawn on top of the page; the
extension does not read or modify what the page contains.

Start. This is the entire point of the extension.offscreen — Chrome's mechanism for running the audio pipeline

Changes
If this policy ever changes, the effective date above will change with it, and
material changes will be noted in the extension's release notes.
