  • email address;
  • notification settings;
  • notification time;
  • profile image, if uploaded by the user.

1.3. Data Entered by the User into the App

Vocalendar is intended for scheduling and lesson tracking, so the user may independently add the following to the app:

  • student information, including name, phone number, contact method, or account used for communication;
  • student photos, if the user chooses to add them;
  • lesson data, including date, time, lesson type, comments, and the list of students;
  • subscription and payment data, including purchase date, number of lessons, price, and remaining lessons;
  • financial data generated based on the information entered by the user into the app.

1.4. Technical Data

When using the app and website, we may receive technical information necessary for operating the service, for example:

  • IP address;
  • device type and operating system;
  • app version;
  • interface language;
  • information about network requests and technical errors.
  • At this time, the app does not use third-party advertising SDKs and does not include embedded analytics for advertising purposes.

2. What Permissions the App May Request

Depending on the device and platform, the app may request access:

  • to the camera, so the user can take a photo for the profile or a student card;
  • to the gallery or photo library, so the user can choose an image for the profile or a student card;
  • to the internet connection, in order to authenticate, sync data, and use the server-side functions of the app.
  • The app only uses permissions that are necessary for the relevant feature and that are triggered by user actions or service settings.

3. How We Use Data

We may use data for the following purposes:

  • registration and account sign-in;
  • email verification and account recovery;
  • storage and synchronization of schedules, lessons, students, subscriptions, and related records;
  • displaying the user profile and settings;
  • operating reminders and notification settings;
  • ensuring account security and preventing unauthorized access;
  • error diagnostics, technical support, and improving service stability;
  • complying with legal requirements and protecting our legitimate interests.

4. Where Data Is Stored

Some data may be stored locally on the user's device, including:

  • local app database data;
  • profile image or student photos if they are selected on the device;
  • session tokens and certain settings in the device's secure storage, if supported by the platform.
  • Some data may be transferred to and stored on our server infrastructure where necessary for authentication, synchronization, and operation of the user account.

5. Disclosure of Data to Third Parties

We do not sell users' personal data.

We may transfer data to third parties only in limited cases:

  • to infrastructure and hosting providers, if necessary for operation of the app and website;
  • to contractors and technical partners who help maintain the service and are required to comply with confidentiality obligations;
  • where such transfer is required by law, by a request from a competent authority, or to protect our rights.
  • We do not transfer user data to advertising networks for targeted advertising, unless this is separately stated in an updated version of this Policy.

6. Data Retention Period

We retain data for the period necessary to:

  • provide the user with Vocalendar functionality;
  • support the account and synchronize data;
  • fulfill contractual and legal obligations;
  • resolve disputes, prevent abuse, and protect our rights.
  • If a user deletes data from the app or requests deletion of the account, we will seek to delete or anonymize the data within a reasonable period unless longer retention is required by law or by legitimate grounds.

7. Legal Bases for Processing

Depending on applicable law, we may process data on the following bases:

  • performance of a contract or providing the user with access to the service;
  • user consent, where required;
  • compliance with legal obligations;
  • our legitimate interests, such as ensuring security, preventing fraud, supporting app operation, and improving service quality.

8. User Rights

Depending on applicable law, the user may have the right to:

  • request access to their data;
  • request correction of inaccurate or outdated data;
  • request deletion of data;
  • restrict processing or object to it;
  • withdraw consent where processing is based on consent;

  • file a complaint with a competent data protection authority.
  • To exercise these rights, the user may contact us using the details provided in this Policy.

9. Children's Data

Vocalendar may be used to keep records of lessons with students; however, the app is not intended for independent use by children as a separate consumer platform.

A user who enters student information into the app is responsible for having appropriate legal grounds for processing such data and for complying with applicable legal requirements.

10. Security

We take reasonable technical and organizational measures to protect data against loss, unlawful access, alteration, disclosure, or destruction. However, no method of transmission over the internet and no storage system can guarantee absolute security.

11. International Data Transfers

If servers, contractors, or infrastructure located outside the user's country are used to operate the service, data may be transferred to other jurisdictions. In such cases, we take reasonable measures to protect data in accordance with applicable law.

12. Changes to the Privacy Policy

We may update this Privacy Policy from time to time. The current version will always be published on this page together with the date of the latest update.

Continued use of the website or app after the changes take effect means the user agrees to the updated version of the Policy, unless otherwise required by applicable law.
