Lemur Terms of Use

Version 0.6 — 9 November 2026

Payments are currently unavailable. The purchase provisions describe a future offer and will apply once sales begin.

1. Publisher and contact

Lemur is published by Marcin Wiśniewski. For game enquiries, email [email protected]. The postal address for correspondence, including complaints to the publisher, is ul. Jana Kazimierza 31B, 01-248 Warsaw, Poland. Phone number for buyer contact: [PUBLIC_PHONE_BEFORE_SALES].

Lemur helps users learn multiplication. An adult chooses how a child uses it; purchases are intended to be made by an adult. The game does not guarantee a particular learning outcome within a particular time.

2. Access and requirements

The current version provides the free Mini Zoo and presents the planned full-version offer. Purchasing and restoring a purchase are not yet available. Free access is not proof of a full-version purchase.

This version requires Android 14 or later and storage space for installation and game data. The game works offline. No online account registration is required. Profiles are local and are not separate password-protected accounts. Anyone using the same device and installation can view and change profiles.

3. Mini Zoo and the full version

Mini Zoo allows multiplication practice with factors 2–5 in both modes, with no limit on days or games. Local profiles, history and progress are available. The full version extends the range to factors 2–9 and further parts of the zoo. Discovering later stages still requires game progress; payment does not replace the learning requirements.

After sales launch, the full version is planned for a one-time payment, with no subscription and for an indefinite period. Google Play will show the total price and currency before payment is confirmed. Access will be granted after Google Play confirms the purchase. If payment is pending, the game will wait for confirmation.

4. Licence and use

The licence is non-exclusive. After purchase, the full version may be used on one device at a time, across all local profiles in that installation. This includes home use or use by one teacher on their personal device, including group lessons. A set of school tablets requires a separate offer.

After changing devices, the full version can be restored as described in section 5. Use on one device at a time is a licence condition. Lemur will not detect or technically block simultaneous use on several devices. Rights granted by Google Play and the user's statutory rights take precedence over these licence restrictions.

You may not sell copies of the game or distribute it or extracted assets without authorisation. This does not restrict acts permitted by law or rights under separate licences for included materials. Zoo maps saved in the game may be kept, printed and shared non-commercially at home and during your own classes. Information about music and other materials is available under Music and licences.

When distributed through Google Play, the store's terms also apply.

5. Purchases and game data

Once payments are launched, a valid purchase can be restored after reinstalling or changing phones without paying again. A compatible device, the same Google Play account used for purchase and an internet connection will be needed. Restoration will cover full-version access. History, profiles and progress remain in the local game save. In the current preview, the restore button reports that payments are unavailable.

Game data is stored on the device. Deleting a profile, clearing app data or uninstalling may cause progress to be lost. The publisher has no server copy from which to restore it. The game does not synchronise between devices. Images saved to the gallery must be deleted separately.

6. Complaints and conformity with the contract

Problems with the game or access to purchased content can be reported to the publisher by email or post using the details in section 1. It helps to describe the problem, game version, device model and Android version, and the requested remedy. An order identifier may help with a purchase issue. A request may be limited to information needed to handle it.

When sales begin, the transaction party, price, and route for payment or refund support will be identified in the checkout, receipt and Google Play terms applicable in the buyer’s country. Contact the publisher for problems with the game. The consumer’s rights against the responsible trader remain unaffected.

Consumers retain statutory rights if digital content is not supplied or does not conform to the contract. These may include requiring conformity and, where the applicable law provides, a price reduction or termination. The time for responding to a complaint depends on applicable law; in Poland it is generally 14 days.

7. Withdrawal from a future purchase

In the EU and the United Kingdom, consumers generally have 14 days from a distance contract for digital content to withdraw without giving a reason. Send the withdrawal notice to the transaction party before the period ends; its details appear in the receipt or store terms. This is not a statement that a 14-day right applies in every country, including the United States. Consumers elsewhere retain the rights provided by their local mandatory law.

For paid digital content supplied without a physical medium, the EU and UK right can be lost after supply begins only where the applicable legal conditions are met. These include the consumer’s express prior consent to supply during the withdrawal period, acknowledgement of the resulting loss of the right, and the required confirmation on a durable medium. Merely reading these terms does not give that consent. The actual checkout and confirmation must satisfy the rules in the buyer’s country.

Example notice: “I withdraw from the contract for the full version of Lemur concluded on […], order ID […]. Name […], address […], date […].” Use of this example is optional. If withdrawal is effective, the transaction party reimburses the consumer as required by applicable law; in the EU and UK this is generally within 14 days of receiving the notice, using the original payment method unless another no-cost method is agreed.

8. Updates and user rights

Changes will be communicated with later versions. An indefinite purchase is not a promise to add new features indefinitely; obligations to provide legally required updates, including those needed for conformity and security, remain. A document change cannot by itself remove acquired access or limit statutory consumer rights.

These terms do not exclude liability that cannot legally be excluded. They do not require a consumer to use only a court where the publisher is established. A consumer may seek help from a consumer adviser or a competent alternative dispute resolution body; the trader's participation depends on applicable law and its position in the matter. Consumers in other countries also retain their applicable mandatory protections.

9. Privacy

The separate Lemur Privacy Policy available in the app explains how data is stored and deleted. Reading it is not consent to marketing or tracking.
