Lekhoni

Terms of Service

Effective date: . Last updated: .

These Terms of Service (“Terms”) govern the use of Lekhoni – Bangla Tracing App and the associated services described on this page. Lekhoni is provided by Zoya TV Kids, operated by Akther Traders B.V., Netherlands.

The same app is listed for Android and for iPhone and iPad with the application id com.zoyatvkids.bangla. On this website it is also called Lekhoni – Learn Bangla Writing. Android is distributed on Google Play. The iPhone and iPad app is distributed on the Apple App Store and is covered by these Terms.

Acceptance of these Terms

A parent or legal guardian should read these Terms before allowing a child to use Lekhoni. Lekhoni is designed for young children and should be used under appropriate adult supervision. The parent or guardian decides whether a child may use the application, on which device, and with which account.

A parent or legal guardian accepts these Terms by installing Lekhoni, by allowing a child to use it, by creating or signing in to a parent account, or by claiming complimentary premium access. If a later version offers an optional paid feature, completing that purchase is also acceptance of these Terms. A child does not enter a contract by tracing letters or numbers. Lekhoni does not ask a child to accept these Terms, to create an account, or to make a purchase.

If you do not agree to these Terms, do not install the app, do not create a parent account, and do not allow a child to use Lekhoni.

About Lekhoni

Lekhoni is an educational application designed to help children learn Bangla handwriting through interactive tracing. It is meant for families.

Current features include:

A lesson can include a writing demonstration that is packaged inside the app. That demonstration plays on the device. Lekhoni does not open YouTube for it. A separate practice page is a free drawing space. A parent or child can choose to save a practice drawing to the device photo library.

Additional educational content and features may be introduced in future updates. A feature described here is part of the app only while that version includes it. Lekhoni is a practice tool. These Terms do not promise that a child will reach a particular writing level, score, or pace.

Eligibility and parental responsibility

Lekhoni is intended for children aged approximately 4–7, under the supervision of a parent or legal guardian. An adult may also use it with a younger or older child when that adult decides it is suitable. The adult is responsible for deciding that the application is appropriate for the child who uses it.

Parents and guardians supervise account management, device permissions, and any optional purchases that may be offered in a later version. Before sign-in, sign-out, account deletion, or a complimentary premium claim, the app asks for the answer to a short arithmetic question. That question is checked on the device. It is a prompt for an adult. It is not an identity document check, and it does not replace supervision.

The adult who controls the device is responsible for the operating system, for app-store accounts on that device, and for permissions the operating system asks for, such as saving a picture to the photo library.

Accounts and authentication

Lekhoni supports optional account authentication through the providers available on the device:

Some educational functionality can be used without signing in. The first five vowels, the first five consonants, and the numbers ০, ১, and ২ can be traced without a parent account.

Certain features, including complimentary premium access and deleting the parent account, require a signed-in parent. A child is not asked to create a Google or Apple account. The parent account is the adult’s account.

Google Sign-In uses the OpenID, email, and profile scopes. Sign in with Apple may share a name on the first authorization. If the parent chooses Hide My Email, Apple may provide a private relay address. After sign-in, Lekhoni stores a parent profile in Firebase for that account: display name when one is provided, email when one is provided, profile photo URL when Google provides one, the sign-in provider, and created and last sign-in times. The account id is the Firebase user id. Child names and learning progress are not part of that profile.

The parent is responsible for activity under that account and for the security of the Google or Apple account used to sign in. Premium stays on the Firebase account that received it. Two sign-ins with the same email address are not merged into one account. Signing in with Apple does not automatically pick up premium that belongs to a separate Google sign-in. The app can attach Google and Apple to one Firebase user, but the current parent screen does not show a control that starts that step.

Sign-out removes the session from that device and clears the local copy of premium status for that account. Sign-out does not delete the Firebase user or the stored parent profile.

A signed-in parent can delete the Lekhoni parent account in the parent area, or by email if the app cannot be used. The steps, what is deleted, and what is kept are on the account deletion page and in the privacy policy. Deletion removes the Firebase login, the parent profile, and premium on that account. It does not erase child profiles, stars, or tracing pictures stored on the device. A promotional claim record is not deleted automatically. If a store purchase record exists for that account, it is not deleted automatically. Lekhoni does not currently process payments or sell in-app purchases.

Free Access and Premium Features

Without complimentary premium access, Lekhoni opens the first five vowels, the first five consonants, and the numbers ০, ১, and ২. Premium is full access to the letter and number tracing set in the current app. It is a parent feature.

Lekhoni is currently available as a free educational application. At present, Lekhoni does not offer paid subscriptions or in-app purchases.

Parents or legal guardians may sign in using a supported authentication provider, such as Google Sign-In or Apple Sign-In where available, and may be eligible to claim complimentary premium access through the “Claim Free Premium Access” feature. In the app, that control is labeled বিনামূল্যে প্রিমিয়াম চালু করুন.

This promotional offer is provided at no cost and does not require payment information. Eligibility and availability may be limited by the terms and capacity of the promotional campaign.

Once complimentary premium access has been successfully granted, it will remain available according to the entitlement conditions communicated at the time of the claim. Reaching the campaign’s participation limit does not, by itself, cancel previously granted entitlements.

A signed-in parent can claim the offer from the parent area while the campaign is open. The number of places is set on the server. A used free place is not returned if the account is later deleted. Deleting the parent account removes premium on that Firebase user. A new sign-in creates a new Firebase user and does not restore a deleted grant. It can receive a new complimentary grant only if the campaign still has a place and the server accepts the claim.

If the same Firebase parent account already has complimentary premium, signing in with that same account on another supported device can read it while the device is online. Signing in with Apple does not automatically pick up premium that belongs to a separate Google sign-in.

After a successful online check, the device keeps a local copy of that account’s premium flag for seven days so full access can continue offline. Sign-out and account deletion clear that copy. The copy does not include child profiles.

Future versions of Lekhoni may introduce optional paid premium features or one-time purchases. Any such purchases will be clearly identified, with applicable prices and conditions displayed before payment. No payment will be charged without the user’s authorization.

Any future purchases will be subject to the applicable app store’s payment terms and mandatory consumer protection laws.

Future purchases and consumer rights

Lekhoni does not currently offer paid subscriptions or in-app purchases, and it does not process payments. Claiming complimentary premium access does not ask for payment information. Lekhoni does not collect a payment-card number. There is no purchase-restoration flow in the current app, because the current app does not sell an in-app purchase.

If a later version introduces an optional paid premium feature or a one-time purchase, the applicable app store will process that payment. The price and conditions will be shown before the parent is charged. Lekhoni will not charge a payment without the parent’s authorization. A purchase already stored for a different parent account will not be moved to another account.

If a later version sells a purchase, a refund of that store charge is requested from the store that took the payment. The store decides store refunds under its policies and applicable law. Contact zoyatvkids@gmail.com if a completed purchase is not reflected on the parent account that was signed in at the time of purchase. Do not send a password, a full payment-card number, or a child’s personal information.

If you are a consumer in the European Economic Area, the United Kingdom, or another country whose law gives you rights that cannot be waived, those rights remain. Nothing in this section removes a statutory remedy for digital content that is not in conformity, including the remedies Dutch and other EU consumer law provide. Those rights apply to Lekhoni where the law gives them, including while the application is free. If a later version offers a paid digital purchase, and a store asks for consent to supply that digital content immediately and for acknowledgement of the effect on a withdrawal right, that request is presented by the store in its purchase flow.

Child profiles, progress, and tracing pictures

A parent can add up to five child profiles so siblings can keep separate progress. The add-child screen asks for a display name, up to 30 characters. It does not ask for a birthday, an age, or a photograph of the child. The app chooses an avatar key. It does not take a camera photo of the child.

For each child, the device stores which child is active, lesson progress, stars, attempt information, practice times, the sound setting, and a picture of a successful trace when the app saves one. The Parent Dashboard can show that progress and those saved successful tracing results. This learning data stays in the app’s private storage on the device. Lekhoni does not upload child names, progress, or tracing pictures to Cloud Firestore or Firebase Storage.

A picture saved to the photo library from the practice page stays in the photo library. Lekhoni does not upload it and does not delete it later. Deleting a child in the parent area deletes that child’s profile and the tracing pictures stored in the app’s files for that child.

Android or iOS backup, if the parent turns it on in the operating system, may copy local app data. Lekhoni does not control those backups. Uninstalling the app or clearing its storage removes the local profiles and pictures that are still only in the app.

Acceptable use

Lekhoni is licensed for personal, household, educational use by a family. A parent or guardian agrees to the following:

We may suspend or close a parent account, or refuse a complimentary premium claim, when these rules are broken or when that step is needed to protect families, the service, or the stores. Refusing a new claim does not, by itself, cancel complimentary premium access that has already been granted.

Intellectual property

Akther Traders B.V. or its licensors own Lekhoni, including the app, the lesson structure, tracing guides, packaged demonstration videos, text, graphics, and the Lekhoni and Zoya TV Kids brands. Bangla letters and numbers, as a writing system, are not our property. Our presentation of them, and the materials that teach them in the app, are.

We grant the parent a personal, non-exclusive, non-transferable, revocable license to use Lekhoni for family learning, subject to these Terms and the rules of the store that supplied the download. The license ends when these Terms end or when the app is removed, except for rights that mandatory law keeps in place.

A child’s tracing and practice drawings belong to the family. We do not take ownership of them. Because those pictures stay on the device unless someone chooses to save a copy to the photo library, we do not receive them and we do not receive a license to publish them.

Privacy

The Lekhoni privacy policy describes what stays on the device, what a parent sign-in stores in Firebase, how complimentary premium entitlements are recorded, that Lekhoni does not currently process payments, how technical diagnostics are handled, and how deletion works. The privacy policy is part of the information a parent should read with these Terms. On a question of personal data, the privacy policy is the detailed statement. These Terms still govern the use of the app.

Lekhoni does not include an advertising SDK. It does not ask children to create an account. It does not use Firebase Analytics to record in-app usage events.

Third-party services

Sign-in, accounts, and premium checks use services we do not own. Lekhoni does not currently use Google Play Billing or Apple In-App Purchase. If a later version adds an optional paid feature, that purchase will use the applicable store’s payment service. The services used today are:

Those providers handle the data their services need under their own terms. Firebase for this app stores Cloud Firestore in the Europe multi-region, and Cloud Functions run in the Netherlands, as described in the privacy policy. A Google or Apple service can still process information outside the family’s country. Their availability is outside our control. Tracing that is already on the device can continue offline. Sign-in and a new premium check need a working connection to the relevant service. A purchase, if one is offered in a later version, will also need a working connection to that store.

Availability, updates, and support

We provide Lekhoni as it is available on the stores and on the device. We may update the app, change or remove a feature, close the complimentary premium campaign, or stop offering the app. Closing that campaign, or reaching its participation limit, does not, by itself, cancel complimentary premium access that has already been granted. An update may be required for sign-in or premium checks to keep working. We do not promise that the service will be uninterrupted, error-free, or kept available for a particular time.

Support for families is by email at zoyatvkids@gmail.com and on the support page. Write from the parent’s own email. Say whether the device is Android or iPhone/iPad. Do not send a password, an identity document, a payment-card number, or a child’s personal information.

Educational purpose

Lekhoni helps children practice Bangla handwriting. It does not replace a parent, a teacher, or a school. Feedback on a trace is an in-app check of that drawing against the lesson. It is not a certificate, a grade, or an assessment of the child. We do not guarantee a learning outcome.

Disclaimers and liability

Mandatory consumer rights stay in force. If you are a consumer, we do not exclude or limit liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, for gross fault, or for any other duty that the law of the Netherlands or another mandatory consumer law does not allow us to exclude. A consumer’s statutory rights in respect of digital content that is not in conformity, including rights under Dutch law implementing the EU rules on digital content, remain available.

Subject to those rights, Lekhoni is provided as available. We do not promise that every device, operating-system version, or store account will work with every feature. We are not liable for learning results, for a store’s decision on the download of the free app, or for a store’s decision on a payment or a refund if a later version offers an optional purchase, or for loss of on-device progress caused by uninstalling the app, clearing its storage, a failed device, or a backup the operating system makes under the parent’s settings.

Where the law allows a limit on liability to a person who is not acting as a consumer, our total liability arising out of Lekhoni in any twelve-month period is limited to the amount that person paid us for Lekhoni in that period, or fifty euros if they paid nothing. That limit does not apply where the law forbids it.

Stopping use and closing an account

A parent may stop using Lekhoni at any time by removing it from the device. A parent with an account may also delete that account, as described on the account deletion page. Deleting the account ends premium on that Firebase user. It does not by itself delete child profiles stored only on the device.

We may suspend or end access to a parent account, or stop providing Lekhoni, if these Terms are broken, if we need to do so for security or legal reasons, or if we discontinue the service. Where it is reasonable and we have an email address for the account, we will write to that address. We may act without advance notice when delay would risk harm, security, or a legal duty.

Ending use does not remove a promotional claim record. If a store purchase record exists for that account, ending use does not remove it either, as the privacy policy describes. Sections that by their nature should continue, including intellectual property, liability within the limits above, and records we must keep, continue after use ends.

Governing law and disputes

These Terms are governed by the laws of the Netherlands. If you are a consumer habitually resident in the European Economic Area or the United Kingdom, you also keep the mandatory protections of the country where you live. Those protections apply where the contract cannot take them away.

The courts of the Netherlands may hear a dispute about these Terms. A consumer living in the European Union may also bring proceedings in the courts of the Member State where that consumer is domiciled, as EU law provides, and we may bring proceedings against that consumer only in those courts. A consumer may also use any out-of-court dispute procedure that is legally available to them. Akther Traders B.V. is not currently committed to a particular private dispute board.

Google Play and the Apple App Store

If you download Lekhoni from Google Play, Google’s Play Terms of Service also apply to that download. Lekhoni does not currently charge a purchase price or process an in-app payment. If a later version offers an optional paid feature, Google’s terms will also apply to that payment. These Terms govern your use of Lekhoni with Akther Traders B.V.

If you download Lekhoni from the Apple App Store, these additional points apply, and Apple’s Media Services terms apply to the store:

Where these Terms and a store agreement both apply, the store agreement controls the relationship with that store. These Terms control the relationship with Akther Traders B.V.

Developer and Trader Contact Information

Lekhoni is offered by a trader established in the Netherlands. For Google Play’s trader information, and for families in the European Economic Area, the trader is:

The Google Play account is an organization account of Akther Traders B.V. and is declared as a trader. Please do not send a child’s personal information, a password, or a payment-card number to the support email.

Changes to these Terms

We may update these Terms. When we do, the effective date and the last-updated date at the top of this page will change. The page will stay at /terms. The updated Terms apply from the effective date shown here. If a parent does not agree to the updated Terms, they should stop using Lekhoni and may delete the parent account. A change does not remove a promotional claim record, or a store purchase record if one exists, that the privacy policy says is kept, and it does not remove a consumer right that mandatory law keeps in place. A change does not, by itself, cancel complimentary premium access that has already been granted.
