Tonic terms of service
Last updated 28 October 2026.
Who we are
Tonic is made by Northpocket Software Inc. (“North Pocket”, “we”, “us”). By installing or using Tonic you agree to these terms. If you do not agree, do not use it.
Your licence to use Tonic
We give you a personal, non-exclusive, non-transferable licence to use Tonic on devices you own or control, for making music, including in public performance, worship services and recordings. Tonic is licensed to you, not sold.
Your account
- Keep your sign-in to yourself; you are responsible for what is done with your account.
- Founding Player spots are closed: no new spot is given. A player who holds one keeps Tonic free for good. A spot, like Tonic given to a beta tester, belongs to the account it was given to and cannot be sold or transferred.
- You must be old enough to agree to these terms where you live, or use Tonic with a parent’s or guardian’s agreement.
Buying Tonic
- Tonic is one purchase, made in the App Store or Google Play. It is not a subscription and does not renew. Beta testers, and players Tonic was given to, do not pay.
- One purchase opens Tonic on every device you sign into with the same Tonic account. Restore purchase on Tonic’s purchase screen brings it back on a new device or a new account.
- The store takes the payment, and its own terms apply to it.
- Refunds go through the store you bought from. App Store: sign in at reportaproblem.apple.com, choose Request a refund, then pick Tonic. Google Play: on play.google.com, open Payments & subscriptions, then Budget & order history, find the order and choose Report a problem. You can also write to us and we will help.
- If a purchase is refunded or reversed, Tonic stops opening for that account the next time it starts. It never stops in the middle of a song.
Your keyboards
Tonic changes your keyboards’ key. Some keyboards need Tonic’s help to do it: Tonic helps only a keyboard you allow, and that keyboard’s own sound is off while it does. Tonic tells you on screen whenever it is helping one, and tries to give the keyboard back when you ask, on Panic and when it quits. If Tonic closes unexpectedly, turn that keyboard’s sound back on yourself; its card in Tonic shows how. Some keyboards cannot confirm what they were sent; Tonic says so and shows that keyboard’s own steps. You remain responsible for your own equipment, for checking it before a performance, and for keeping backups of what is stored on it.
Tonic works with keyboards made by others. Their names are trademarks of their owners, used only to say what Tonic works with; no keyboard maker makes or endorses Tonic.
Using it fairly
Do not:
- sell or share access to an account;
- copy, decompile or reverse-engineer Tonic, except where the law allows it regardless of these terms;
- interfere with our servers, test them for weaknesses without our written permission, or send automated requests;
- use Tonic to break the law or anyone else’s rights.
Ending this agreement
You can stop at any time: delete the app, and delete your Tonic account (see the privacy policy). We may suspend or close an account that breaks these terms, after telling you why where we can. What these terms say about liability and the law keeps applying after they end.
Warranty and liability
Tonic is provided “as is”. As far as the law allows, we do not promise it will be free of faults or suit every keyboard, and we are not liable for indirect or consequential loss, including a performance interrupted, or for loss of data or income. As far as the law allows, our total liability to you is limited to what you paid us in the 12 months before the claim. Nothing here limits rights you have under consumer law that cannot be limited.
Apple
If you got Tonic from the App Store: these terms are between you and North Pocket, not Apple. Apple is not responsible for Tonic or its content, has no duty to provide maintenance or support for it, and is not responsible for any claim about it, including product liability, legal compliance or intellectual-property claims. If Tonic fails to meet any warranty that applies, you may tell Apple and Apple will refund the purchase price, if any; Apple has no other warranty obligation. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them. You confirm you are not in a country under a U.S. government embargo and are not on a U.S. government list of restricted parties.
Governing law
These terms are governed by the laws of Canada that apply where North Pocket is based. Disputes go to the courts there, unless the law where you live gives you the right to bring them at home.
Changes
When these terms change, we update the date at the top. If a change matters to you, we will say so in the app before it takes effect.
