Before you subscribe
You are buying software that drafts charts from your audio files. It does not guarantee chord-for-chord accuracy. Internal benchmarks average about 40% bar-level chord agreement with reference labels across 50 test songs; individual songs vary widely. Refunds follow Lemon Squeezy’s refund policy — try a song you know well first and use the built-in editor if names are off. Full disclaimer.
What a license includes
- Desktop app — opens in its own window. Mac DMG or Windows zip; double-click, no installer script.
- Library — save songs, search, sort, star favorites, and edit title, artist, and tags on this PC.
- Local charts — drop an MP3, set song key / meter / BPM, toggle 7th chords, transpose or capo, optional lyrics, save a PDF.
- Private — songs never leave this PC.
After you pay
- Download from the Releases table on the home page. The how-to guide is in the same folder.
- Open Chord Chart and enter the email used at checkout.
- This computer uses one registered PC slot the first time you activate. For a laptop and a desktop, buy an Extra PC license.
Your checkout email is not a password, but do not share it — someone else could register your PC slot first. A second computer needs an Extra PC license. The annual term starts at checkout. Renewing the 1 PC license early keeps your remaining time and adds one year (still one PC slot). Each Extra PC adds another slot and has its own yearly term from Lemon. The app shows your end date and reminds you in the last 7 days. Subscriptions renew yearly until you cancel. Sharing one Mac or PC? Use separate macOS or Windows user accounts so each person keeps their own checkout email, PC slot, and song library (each person pays separately). Forgot your checkout email? Check your Lemon Squeezy purchase receipt (order confirmation email), or email [email protected] with an approximate purchase date.
