Privacy policy

1. Information we use

Account information: your email, account identifier, chosen name, birthday, languages, goal, time zone, learning reason and preferences. A profile photo is optional. Authentication is used to secure your account; your password is not included in your learning-data export.

Learning information: your private packs, words, answers, examples, review ratings, schedules, activity and exam attempts. Files you choose to upload may be stored with your account. Text and CSV imports are read on your device and the resulting cards can be synchronized.

Support information: ticket subjects, categories, statuses and messages are stored so the support team can help you. They are private to you and authorized administrators and may be retained for recovery after account deletion.

Community information: publishing a pack makes its words and examples visible to other signed-in learners, who may save independent copies. Making the original private does not delete those copies. Reports are private support conversations and creator blocks are private account preferences. Account records may be retained for recovery after deletion.

Technical information: hosting and authentication providers may process IP addresses, request times and security/error information to operate and protect the service. Local storage holds sessions, settings, cached learning data, unfinished exams and changes awaiting synchronization. Avoid uploading sensitive personal information about yourself or others.

2. Why we process it

We use account and learning data to provide the features you request, synchronize your library and calculate progress. Where applicable, the legal basis is performance of the service agreement. We use limited technical information to secure the service, prevent abuse and diagnose failures, based on legitimate interests where that basis applies.

Notification permission is optional and controlled by your device. Daily reminders are scheduled locally. You may disable them in Lerzai or your device settings. When you request AI-generated content, your input and selected languages are sent to an AI service to generate a response. We do not use your private learning content to train an AI model.

When advertising is enabled in the app, Google advertising services may process device identifiers, IP address, approximate location and ad interaction information to provide and measure ads. Where required, a consent message lets you accept, decline or manage choices, and you can revisit available choices in the app. Rewarded ads are optional. Google explains its advertising practices at https://policies.google.com/technologies/ads.

3. Providers and access

We use service providers for authentication, data and file storage, hosting and distribution. They receive the information needed to provide those services and may retain limited operational records according to their security practices and applicable requirements.

Authorized administrators can access account details, learning progress, packs and cards to operate the service, handle support and moderate content. Technical maintenance may require restricted access to stored data. We may disclose information where legally required or needed to protect rights and service security.

4. International processing

Lerzai is available internationally. Our configured learning database is in a European region; hosting, authentication operations, distribution and storage providers may process information in other countries. Protections and rights may differ by location. Contact us for information about relevant providers, processing locations and safeguards applicable to your account. International availability does not mean every country has identical privacy rules.

5. Storage and deletion

We keep your account and learning data while your account is active. Deleted packs, cards and related information may be retained on the service for recovery and are not shown in normal use. Contact us for details about retention or a request to erase data.

In your account settings, you can request an export or delete your account after confirming your password. Deletion deactivates the account; associated data and uploaded files may be retained for recovery. Contact us to request information about retention or erasure.

Signing out does not necessarily erase that account’s private offline cache from the device. The app restricts access through account sessions; someone controlling the device or its storage may still access locally stored files. In-app account deletion clears the current device cache. Remove app/site data separately from other devices, or uninstall the app, when disposing of them.

6. Your choices and rights

Depending on your location, you may have rights to access, correct, erase or receive a portable copy of information, restrict or object to processing, withdraw an optional permission and complain to a data-protection authority. Regional rights and exceptions differ. Use the in-app export/delete controls or email contract@aminehalal.com from your account email. We may verify ownership and respond within the deadlines applicable to your request.

You can edit your display name and languages in settings and edit or delete your learning content. Device permissions can be changed in system settings. We do not charge for exercising a privacy right unless a permitted exception applies.

7. Young users and security

Lerzai is intended for people aged 16 or older who can accept these terms under local law. It is not directed at children under 16. If you believe an underage person has provided information, contact us so we can investigate and remove it when appropriate.

We use encrypted transport, authenticated account access, database ownership controls and private upload/download authorization. No system is perfectly secure. Protect your password, email and devices, and notify us if you suspect unauthorized access.

8. Updates and contact

We may update this notice as the product or processing changes. The date above identifies this version. Material changes will be brought to users’ attention where required. For privacy questions or requests, contact contract@aminehalal.com.
