1. What Information Do We Collect?
Personal information you disclose to us
In Short: We collect very little personal information, and only what you choose to provide.
The app does not require you to create an account, and we do not ask for your name, email address, or other contact details in order to use it. We only receive personal information that you voluntarily provide — for example, if you contact us directly by email.
- Sensitive Information. We do not process sensitive information.
- Payment Data. If you choose to purchase a subscription, your payment is processed entirely by Apple Inc. through the App Store. We do not receive or store your payment instrument number or security code. You may find Apple’s privacy notice here: https://www.apple.com/legal/privacy/en-ww/.
Information stored on your device
In Short: Your learning progress is stored locally on your device and is not transmitted to us.
The app saves your learning progress (such as completed lessons) locally on your device using the operating system’s standard storage. This information stays on your device, is not sent to our servers, and is removed when you delete the app.
All personal information that you provide to us must be true, complete, and accurate, and you must notify us of any changes to such personal information.
2. How Do We Process Your Information?
In Short: We process the limited information described above only to operate the app and respond to you.
We process information for the following purposes:
- To provide and maintain the app. This includes saving your learning progress on your device so you can continue where you left off.
- To process purchases. Subscriptions are handled by Apple; we use the resulting purchase status to unlock premium features.
- To respond to your inquiries. If you email us, we use your message and email address to reply.
- To comply with law. We may process information where required to meet our legal obligations.
3. When and With Whom Do We Share Your Personal Information?
In Short: We do not sell your personal information. We may share information only in the limited situation described below.
We may need to share your personal information in the following situation:
- Business Transfers. We may share or transfer your information in connection with, or during negotiations of, any merger, sale of company assets, financing, or acquisition of all or a portion of our business to another company.
4. How Long Do We Keep Your Information?
In Short: We keep your information for as long as necessary to fulfill the purposes outlined in this Privacy Notice unless otherwise required by law.
We will only keep your personal information for as long as it is necessary for the purposes set out in this Privacy Notice, unless a longer retention period is required or permitted by law (such as tax, accounting, or other legal requirements).
When we have no ongoing legitimate business need to process your personal information, we will either delete or anonymize such information, or, if this is not possible (for example, because your personal information has been stored in backup archives), then we will securely store your personal information and isolate it from any further processing until deletion is possible.
Your learning progress is stored locally on your device, not on our servers, and remains there until you delete it or remove the app.
5. How Do We Keep Your Information Safe?
In Short: We aim to protect your personal information through a system of organizational and technical security measures.
We have implemented appropriate and reasonable technical and organizational security measures designed to protect the security of any personal information we process. However, despite our safeguards and efforts to secure your information, no electronic transmission over the Internet or information storage technology can be guaranteed to be 100% secure, so we cannot promise or guarantee that hackers, cybercriminals, or other unauthorized third parties will not be able to defeat our security and improperly collect, access, steal, or modify your information. Although we will do our best to protect your personal information, transmission of personal information to and from our Services is at your own risk. You should only access the Services within a secure environment.
6. Do We Collect Information From Minors?
In Short: The app is rated 4+ and suitable for all ages. We do not knowingly collect personal information from children.
The app is intended to be appropriate for users of all ages, including children, and carries a 4+ age rating on the App Store. Because the app does not require an account and does not collect personal information from any user, we do not knowingly collect personal information from children. If you believe we have somehow received personal information from a child, please contact us at krznenimacor@gmail.com and we will take reasonable steps to delete it.
7. What Are Your Privacy Rights?
In Short: Depending on where you live, you may have rights regarding your personal information under applicable privacy laws.
Depending on your location, you may have the right to request access to, correction of, or deletion of any personal information we hold about you. Because the app works without an account and stores your progress locally on your device, you can also remove all locally stored data at any time by deleting the app. To make a privacy request, email us at krznenimacor@gmail.com.
Withdrawing your consent: If we are relying on your consent to process your personal information, which may be express and/or implied consent depending on the applicable law, you have the right to withdraw your consent at any time. You can do so by contacting us using the contact details provided in the section “How Can You Contact Us About This Notice?” below.
However, please note that this will not affect the lawfulness of the processing before its withdrawal nor, when applicable law allows, will it affect the processing of your personal information conducted in reliance on lawful processing grounds other than consent.
If you have questions or comments about your privacy rights, you may email us at krznenimacor@gmail.com.
8. Controls for Do-Not-Track Features
Most web browsers and some mobile operating systems and mobile applications include a Do-Not-Track (“DNT”) feature or setting you can activate to signal your privacy preference not to have data about your online browsing activities monitored and collected. At this stage, no uniform technology standard for recognizing and implementing DNT signals has been finalized. As such, we do not currently respond to DNT browser signals or any other mechanism that automatically communicates your choice not to be tracked online. If a standard for online tracking is adopted that we must follow in the future, we will inform you about that practice in a revised version of this Privacy Notice.
9. Do We Make Updates to This Notice?
In Short: Yes, we will update this notice as necessary to stay compliant with relevant laws.
We may update this Privacy Notice from time to time. The updated version will be indicated by an updated “Revised” date at the top of this Privacy Notice. If we make material changes to this Privacy Notice, we may notify you either by prominently posting a notice of such changes or by directly sending you a notification. We encourage you to review this Privacy Notice frequently to be informed of how we are protecting your information.
10. How Can You Contact Us About This Notice?
If you have questions or comments about this notice, you may email us at krznenimacor@gmail.com.
11. How Can You Review, Update, or Delete the Data We Collect From You?
You have the right to request access to the personal information we hold about you, details about how we have processed it, to correct inaccuracies, or to delete your personal information. You may also have the right to withdraw your consent to our processing of your personal information. These rights may be limited in some circumstances by applicable law.
