Terms of Service

Last updated: 11 July 2026

These Terms govern your use of the Jam Jam mobile app and the jam-jam.org website (together, the “Service”). By using the Service you agree to these Terms. If you do not agree, do not use it.

These Terms are provided in several languages for convenience. In case of discrepancy, the French and English versions prevail.

1. The Service

Jam Jam is a music companion: a chord notebook, jam tools, melody editor, import helper and backing-track generator. The core app runs on your device and is fully usable without an account and without an internet connection. A web app is also available on jam-jam.org — songbook, composer, keyboard and tuner in your browser, kept in sync with the mobile app through your account.

2. Accounts

An account is optional and only enables social and sync features. You sign in with an email one-time code or a supported provider (e.g. Google). You are responsible for the activity on your account. One active session per environment is allowed — a web session and a mobile session can be open at the same time (they stay in sync).

3. Your content

You keep all rights to the songs, chords, lyrics and melodies you create or import (“Your Content”), stored on your device. If you share content with friends or make it public, you grant us a limited licence to host and transmit it solely to provide those features.

You are responsible for ensuring you have the right to use, import and share Your Content. Do not upload content that infringes others’ rights. Sharing is for private and friend-to-friend use, not public redistribution of copyrighted works.

4. Acceptable use

Don’t break the law or infringe others’ rights.
Don’t upload illegal, hateful, or sexually explicit material (avatars are moderated).
Don’t abuse, overload, reverse-engineer or disrupt the Service.
Don’t impersonate others or create fake accounts.

5. Subscriptions & pricing

Premium is offered as an auto-renewing monthly or yearly subscription, or as a one-time lifetime purchase. You can buy it through two channels: (a) inside the mobile app via the app store (Google Play, and the Apple App Store where available), or (b) directly on jam-jam.org. It is the same single Premium, unlocked across all your devices whatever the channel; store prices are higher only to absorb the store’s commission.

Store purchases (a): billing, renewal and cancellation are handled by the store under its own terms. Subscriptions renew until cancelled in your store account; manage or cancel them there.

Direct purchases on jam-jam.org (b): the seller is the publisher of Jam Jam (see “Publisher” below). Payment is handled by our processor Stripe. Prices are shown inclusive of VAT. Monthly and yearly subscriptions renew automatically until you cancel; you can cancel at any time from “Manage my subscription” (via the Stripe customer portal), and cancellation takes effect at the end of the current paid period — you keep Premium until then. The lifetime plan is a single payment valid for as long as the Jam Jam service is operated. Your invoices are available at any time from the same management portal, and we send a reminder email before each annual renewal.

Subscription prices may change over time. If you have an active subscription, you keep your current price for as long as your subscription remains active, even if the price increases for new subscribers. If you cancel and later resubscribe, the price in force at that time applies.

The scope of the free tier and of Premium may evolve: features that are free today may become Premium, and new features may be offered as Premium-only. A lifetime purchase you have already made is never revoked.

6. Purchases, refunds & right of withdrawal

For store purchases, refunds are handled by Google Play (or the Apple App Store) under their own policies. For direct purchases on jam-jam.org, your card details are processed by Stripe and are never stored by Jam Jam; likewise, store payment details are handled by the store and never stored by us.

EU consumers, right of withdrawal: Premium is digital content supplied immediately. At checkout you expressly request immediate performance and acknowledge that Premium is available to you right away. For direct purchases on jam-jam.org, you keep a 14-day right of withdrawal: if you withdraw within 14 days, we refund the amount paid in proportion to the service already provided (pro-rata), in accordance with Article L221-28 of the French Consumer Code. For store purchases, the store’s own refund policy applies.

7. Automatic Assistant

The in-app Automatic Assistant helps clean up imported songs and suggest content. Results may be imperfect and you remain responsible for what you keep.

8. Disclaimers & liability

The Service is provided “as is”, without warranties. To the extent permitted by law, we are not liable for indirect damages or loss of data. Keep your own backups.

9. Termination

You may stop using the Service and delete your account at any time from the app. We may suspend access that violates these Terms.

10. Publisher, governing law & mediation

The Service is published by an individual entrepreneur (auto-entrepreneur) registered in France. These Terms are governed by French law, without depriving consumers residing in the EU of the mandatory protections of their country of residence.

In accordance with Articles L612-1 et seq. of the French Consumer Code, consumers may use a consumer mediation service free of charge before any court action. EU consumers may also use the European Commission’s online dispute resolution facilities, where available. Contact us first at [email protected] — most issues are resolved directly.

11. Changes & contact

We may update these Terms; material changes appear here with a new date. Questions: [email protected].
