Flash Chord is free and it will always be free. It's free to use ("free as in beer") and it's free to use ("free as in freedom"). What does that mean? It means that you won't ever pay a dime to use Flash Chord and it's an open source tool, so you're free to see what Flash Chord is doing and how it's being done.
That being said, Flash Tool is not "free" in the sense that it takes time to build and maintain. It also costs actual money to host and renew the domain each year. While these costs are not a lot, everything adds up.
If you use Flash Chord, if you find it useful, and if you'd like to help support it, please consider making a donation.
While we could seek out other forms of advertising, that really doesn't sound like much fun. Plus, lots of people run ad blockers anyway.
If you'd like to make a donation to say thanks and to help support Flash Chord, you can do so below. Any amount would be greatly appreciated. Even if you choose to not make a donation, your use of Flash Chord is still appreciated. :)
