Terms of use
Last updated November 13, 2026
These terms cover the TuneLever app and this website. By using the app you agree to them. If you don’t agree, please don’t use the app. “TuneLever”, “we” and “us” mean the makers of the app.
What the app does
TuneLever measures your piano through your phone’s microphone and coaches you, step by step, through tuning it yourself. It can tell you when a piano is better left to a technician (piano tuner). It is a guide, not a technician in the room.
Tuning a piano carries risk
Please read this part carefully.
- A piano string is under high tension. It can break, and a broken string can whip. Wear safety glasses while you tune.
- Turning the wrong peg (tuning pin), or turning too far, can break a string or harm the peg or the piano. Turn in small amounts, and stop when the app tells you to stop.
- The app’s checks lower these risks. They can’t remove them. You choose whether to tune, and you are the one turning the lever.
- When the app says to call a technician, please do. Old pianos, pianos far below pitch, loose or very tight pegs, and rusty strings need someone who can see the piano.
We do not promise any particular result. How a piano sounds after tuning depends on the piano, its condition, the room, and the care taken.
Free features
The “Can I tune it?” check, the Snapshot and tuning map for one piano, the tool list, the first lessons and practice drills, and the first coached note are free.
Passes
- A DIY pass gives one month of full coaching. It starts when you buy it.
- A pass does not renew. Nothing more is charged when it ends. Buying another pass while one is active adds a month to the end.
- A tuning or pitch raise you started during a pass can be finished up to 7 days after the pass ends.
- When a pass ends, your pianos, Snapshots, history and reports stay. Nothing you made is taken away.
- Prices are shown in the store before you buy and may differ by country.
Refunds
- Bought on an iPhone or iPad: Apple handles refunds. Ask at reportaproblem.apple.com.
- Bought on Google Play: if you ask within 7 days of buying, we’ll refund the pass. Email us with the order number from your Google Play receipt.
- Nothing here limits any refund rights you have under the law where you live.
Using the app fairly
Please don’t copy, resell, or try to get around the pass checks in the app, or interfere with our server. The app, its illustrations and its text belong to us. Your pianos and tunings belong to you.
App store terms
If you got the app from the App Store, Apple’s standard license agreement for apps also applies. If you got it from Google Play, Google Play’s terms apply to the purchase. Apple and Google are not responsible for the app or for support.
No warranty, and limits on our liability
The app is provided as it is. To the extent the law allows, we make no promises beyond those in these terms, and we are not liable for damage to a piano or for indirect losses that come from tuning it. If we are found liable, our total liability is limited to what you paid us for passes in the 12 months before the claim. Some places don’t allow these limits, so they may not apply to you.
Changes
We may update these terms. We’ll post the new version here and change the date at the top. A change never takes away a pass you have already bought.
