Privacy Policy

Jamsic is designed to keep your musical and practice information on your device and to minimize data transmission.

1. Overview

Jamsic is developed by JJ Studio Entertainment as an offline-first music practice and organization app. No Jamsic account is required, no Jamsic cloud account exists, and JJ Studio Entertainment does not operate a Jamsic backend that stores your repertoire or practice data.

The current version does not use analytics SDKs, advertising SDKs, behavioral tracking, cross-app tracking or third-party ad tracking. Jamsic does not create a user profile and does not upload your musical or practice data to JJ Studio Entertainment.

The current App Store privacy declaration for Jamsic is Data Not Collected. The iOS Privacy Manifest declares tracking as disabled and does not declare collected data types or tracking domains.

2. Information stored locally by Jamsic

You can create and store information such as song titles, artist or band names, repertoire information, song status, practice plans, practice sessions, practice progress, rehearsal information, rehearsal issues, gig information, settings and preferences.

This information is stored locally on your device. Jamsic currently does not transmit it to a Jamsic server and does not provide Jamsic cloud synchronization.

Data stored locally by the app is different from data collected or transmitted by the developer. Jamsic is designed so that your musical and practice information remains local unless you independently choose to share information outside the app.

3. Microphone and tuner

Jamsic requests microphone access only for the chromatic tuner. The microphone is activated only when you choose to use the tuner.

  • Audio is analyzed locally to detect instrument pitch.
  • Audio is processed temporarily in memory.
  • Audio is not recorded for storage by Jamsic.
  • Audio is not saved or uploaded.
  • Audio is not transmitted to JJ Studio Entertainment.
  • Audio is not used for analytics or advertising.

You can deny or later change microphone permission through the privacy settings provided by iOS or Android. Without microphone access, the tuner cannot listen to your instrument.

4. In-app purchases

Jamsic offers an optional one-time purchase called Jamsic Pro Lifetime. It is a non-consumable lifetime unlock and is not a subscription.

Purchases are processed by the platform store: Apple App Store / StoreKit on Apple platforms and Google Play / Google Play Billing on Android. JJ Studio Entertainment does not directly process your credit card number, bank account information, Apple ID payment credentials or Google payment credentials.

Jamsic may store a small local entitlement state needed to continue recognizing an already accepted Pro access while offline. This local state is not an advertising identifier, is not used for profiling and is not sent to a Jamsic backend.

Jamsic does not persist purchase receipts, StoreKit JWS payloads, payment tokens or sensitive payment credentials as ordinary app data. The applicable store remains the authority for purchases and eligible restorations.

5. Analytics, advertising and tracking

Jamsic currently does not use analytics services, advertising SDKs, personalized advertising, cross-app tracking, tracking pixels, behavioral profiling or advertising identifiers for tracking.

There are currently no ads in Jamsic.

6. Third-party platform services

The principal external platform services relevant to Jamsic are Apple App Store / StoreKit and Google Play / Google Play Billing. These services may process information necessary to provide purchases, purchase verification and restoration according to their own privacy policies and platform terms.

This does not mean that JJ Studio Entertainment receives your complete payment credentials.

7. External links

Jamsic may provide links to the Jamsic website, this Privacy Policy or the Support page. These links open in the system browser. Jamsic does not include an unrestricted web browser.

When you leave Jamsic and use an external website or service, that website or service may apply its own privacy policy and terms.

8. Other device data and permissions

The current Jamsic experience does not depend on precise location, contacts, calendar, camera, photo library, health data or social media accounts.

The primary sensitive device permission used by Jamsic is microphone access for the tuner.

9. Data retention and deletion

Because your musical and practice data is stored locally, JJ Studio Entertainment does not keep a Jamsic server copy that can be remotely deleted on your behalf.

Where Jamsic provides reset or delete-data functionality, deleting local data removes the locally stored musical and practice information covered by that action. Jamsic is designed to preserve the local Pro entitlement cache during an internal local-data reset so an already recognized purchase is not treated as disposable musical data.

Uninstalling the app may remove local data that is not otherwise preserved by the operating system. Because Jamsic currently has no Jamsic Cloud, local musical and practice information may not be recoverable after deletion or reinstallation. Eligible store purchases are separate and may be restorable through the relevant store.

10. Children's privacy

Jamsic is not designed specifically as a child-directed service. It does not provide social features, chat, public profiles, user-generated content sharing, gambling, loot boxes or adult content.

Jamsic does not require a Jamsic account and the current app does not collect personal information through a Jamsic backend. Parents and guardians can use the device and platform controls provided by Apple or Google when appropriate.

11. Security

Jamsic minimizes the information that needs to leave the device. Local app data benefits from the security protections made available by the operating system and device.

No device, software or storage method can guarantee absolute security. Jamsic does not claim end-to-end encrypted cloud storage or server encryption because Jamsic currently does not operate a cloud storage service for your musical and practice data.

12. International users

Jamsic itself currently keeps your musical and practice data on your device. Apple and Google may operate platform services in multiple countries and may process store-related information under their own policies, contractual safeguards and applicable laws.

If you access external websites from Jamsic, those services may also process normal web requests according to their own practices.

13. Future services

Jamsic may evolve. If future online, cloud or other services change how data is handled, this Privacy Policy will be updated before or when those features become applicable.

Future online services, if introduced, may be offered separately.

14. Changes to this Privacy Policy

We may update this Privacy Policy when Jamsic features, platform requirements, store services or applicable laws change. The “Last Updated” date will be revised when a new policy version is published.
