This policy explains what data may be processed when you use Concert App, why it is used, and what choices are available to you.

Concert (“the App”) is operated by a private individual.
For privacy and data protection inquiries: vladimirananev073@gmail.com

This Privacy Policy explains what data may be processed when you use the App, for what purposes it is used, how it is stored, and what choices are available to you.

1. Age Restriction

The App is intended for users who are 16 years of age or older. We do not knowingly collect personal data from children under 16.

If we become aware that personal data of a child under 16 has been submitted through the App, we may delete that information to the extent reasonably possible.

2. Scope of This Policy

This Policy applies to the App itself and to related authentication, synchronization, subscription verification, storage, and support processes.

It does not govern data processing by third-party services acting under their own privacy policies, including Apple, Google, Firebase, and storefront billing providers.

3. What Data May Be Processed

3.1 Use Without an Account

The App may be used in guest mode.

In guest mode:

  • user content is generally stored locally on your device;
  • app settings and technical state may also be stored locally;
  • guest-mode data is generally not sent to the cloud database unless and until you sign in and use migration or synchronization features.

Local guest-mode data may include:

  • tracks;
  • lyrics;
  • chords;
  • setlists;
  • notes;
  • folder structure;
  • app settings such as theme and language;
  • locally cached session and access data, where applicable.

3.2 Account and Authentication Data

If you create or use an account, the following may be processed:

  • email address;
  • Firebase user ID or a similar account identifier;
  • technical data about the sign-in method;
  • service data necessary for account-based functionality.

Depending on platform and availability, the App may support:

  • email/password sign-in;
  • Google Sign-In;
  • Sign in with Apple.

For ordinary use of the App, we do not intentionally require your phone number, postal address, or precise geolocation.

3.3 User Content

We process the content you create in the App, including:

  • track titles;
  • author names entered by you;
  • lyrics;
  • chords;
  • setlists;
  • notes;
  • folders and related structure;
  • data related to trash, restore, and deletion status.

If cloud synchronization is enabled for your account, such content may be stored in cloud infrastructure associated with your account.

3.4 Subscription and Access Data

If you purchase, restore, or use Pro access, the App may process subscription-related data, including:

  • subscription status;
  • entitlement/access status;
  • platform or storefront information;
  • purchase token, transaction ID, or similar verification data;
  • timestamps related to verification;
  • locally stored data used to determine access to paid features.

We do not collect or store your bank card number or other full payment card details. Payments are processed by the relevant app store or billing provider.

3.5 Legal Consent Records

If the App requires confirmation that you have reviewed legal documents or given required consent, records of such consent may be processed, including the time of confirmation and related technical metadata.

3.6 Technical and Diagnostic Data

We may process a limited amount of technical data necessary to operate, protect, debug, and support the App, including:

  • technical state related to authentication, synchronization, and purchase verification;
  • error messages and service logs;
  • technical cloud records related to transitions between guest and signed-in modes;
  • app and device environment data made available by the platform or third-party SDKs as part of their ordinary operation;
  • IP address and network metadata that may be processed by third-party services as part of normal service delivery.

Based on the current implementation, we do not claim the use of advertising SDKs, behavioral profiling, targeted advertising analytics, or built-in ad networks.

4. How Data Is Used

Data is used only for legitimate app-operation purposes, including to:

  • create and maintain your account;
  • support guest mode and signed-in mode;
  • store and synchronize your content across your devices;
  • support tracks, setlists, folders, lyrics, chords, and notes;
  • provide and verify access to Pro features;
  • maintain security and prevent abuse or technical failures;
  • troubleshoot errors and preserve service integrity;
  • comply with legal obligations;
  • respond to support requests and deletion requests.

We do not sell your personal data.

Based on the current implementation, we do not use your data for ad sales or behavioral advertising profiling.

5. Legal Bases for Processing

Where applicable law requires a legal basis for data processing, we may rely on one or more of the following:

  • performance of a contract — to provide the App and its features to you;
  • legitimate interests — to protect, maintain, fix, and improve the App;
  • compliance with legal obligations — to keep necessary records and respond to lawful requests;
  • consent — where consent is legally required or explicitly requested inside the App.

6. Third-Party Services

The App may use third-party services, including:

  • Firebase Authentication;
  • Cloud Firestore;
  • Cloud Functions;
  • Google Sign-In;
  • Sign in with Apple;
  • Google Play Billing;
  • Apple App Store billing;
  • external resources related to hosting legal documents or service information.

Such services may process data in accordance with their own privacy policies, including technical identifiers, IP address, authentication data, purchase-related information, and service logs necessary for their operation.

7. International Data Transfers

Because the App uses third-party cloud and platform infrastructure, data may be processed on servers located outside your country of residence.

By using the App, you understand that data may be transferred to and processed in jurisdictions where the level of data protection may differ from that in your country, subject to the safeguards used by the relevant providers.

8. Data Retention

We retain data only for as long as necessary for the operation of the App and for the purposes described in this Policy.

In practice, this may mean the following:

  • local guest-mode data remains on the device until you delete it, clear app data, uninstall the App, or otherwise change the usage mode;
  • account-linked cloud data may be retained while the account remains active and while needed for App functionality;
  • deleted user content may temporarily remain in trash or restore state where such functionality exists;
  • subscription, access verification, and technical records may be retained longer to preserve service integrity, prevent abuse, handle disputes, and comply with legal obligations.

If the App uses a trash feature, deleted items may remain there for a limited period before permanent deletion.

9. Account Deletion and Local Data

You may delete your account using available in-app functionality or contact us by email.

When an account or data is deleted:

  • account-linked cloud data may be deleted or scheduled for deletion;
  • local data may be removed from the active App database on the device;
  • certain cached data, preferences, logs, or third-party service records may remain temporarily until cleanup completes;
  • deletion may be delayed or partially fail due to lack of connectivity, the need for re-authentication, or third-party service unavailability.

10. Security

We use reasonable technical and organizational measures intended to protect the data processed by the App, including secure data transmission where supported by the services in use.

However, no method of storage or transmission can guarantee absolute security. You are responsible for the security of your device, operating system, and account credentials.

11. Your Rights

Depending on your jurisdiction, you may have rights:

  • to access your data;
  • to correct inaccurate data;
  • to delete data;
  • to restrict or object to certain processing;
  • to withdraw consent where processing is based on consent;
  • to lodge a complaint with a competent supervisory authority.

To exercise such rights, contact: vladimirananev073@gmail.com

We may ask you to verify your identity before fulfilling a request.

12. Payments

The App may offer optional paid subscriptions for Pro features.

Payments, renewals, cancellations, and refunds are handled by the relevant app store or billing platform. Depending on the platform and build, this may include Google Play and Apple App Store.

We do not receive your full payment card details. From storefronts and billing providers, we may receive only technical information necessary to confirm purchase status and access to features.

13. What We Do Not Intend to Require for Ordinary Use

Based on the current implementation, for ordinary use of the App we do not intend to require:

  • precise geolocation;
  • phone number;
  • postal address;
  • camera access;
  • microphone access;
  • contacts access;
  • public profile data;
  • social graph data;
  • public communication features.

Based on the current implementation, we also do not declare the use of built-in advertising, ad SDKs, or behavioral advertising tracking tools.

14. Changes to This Policy

We may update this Privacy Policy from time to time. The current version may be published in the App, on this website, or in another official source designated by us.

Your continued use of the App after the updated version takes effect means that you have reviewed the updated version.
