1. General provisions and the Seller's details

1.1. This document (hereinafter the "Offer") is an official proposal (a public offer) by the Seller to conclude a licence agreement for the grant of the right to use the additional functionality of the browser game Misteria Vale on the terms set out below. The right is granted on the terms of a simple (non-exclusive) licence; the price of a Package is the remuneration for the grant of the right.

1.2. The Seller's details:

1.3. The Offer is addressed to natural persons using the Game (hereinafter "Users"). Sales are made in roubles of the Russian Federation; payment is accepted through Russian payment infrastructure, and fiscalisation is carried out under the legislation of the Russian Federation on the use of cash register equipment; the functionality for purchasing Packages is not addressed to users outside the territory of the Russian Federation.

1.4. The Game is intended for an adult audience (information product mark — 18+). By accepting the Offer, the User gives the Seller an assurance (Article 431.2 of the Civil Code of the Russian Federation) that: they have reached the age of 18 and have full legal capacity; and that the means of payment used belongs to them or is used with the consent of its owner.

1.5. This Offer applies exclusively to the purchase of Packages directly on the Website (https://misteriavale.com). If the Game is launched through a third-party gaming or distribution platform, the purchase of in-game resources is made on that platform, under its rules and through its payment facilities; the platform is the party to such a settlement with the User, and this Offer does not apply to that settlement. At the same time, section 6 of this Offer (the legal properties of Mana) applies to the use of Mana regardless of the channel in which it was acquired: the scope of the right granted, its term, the manner of its expenditure and the consequences of its withdrawal are the same for all Users. The rules for using the Game as a whole are determined by the Terms of Use (clause 3.3).

2. Terms and definitions

2.1. Game — the browser detective game Misteria Vale, available at https://misteriavale.com, including its software components, interface, content and additional functionality.

2.2. Account — the User's account in the Game, on which the Mana belonging to the User is recorded.

2.3. Mana — an in-game resource in units of which the scope of the right to use the additional functionality of the Game is expressed. The legal properties of Mana are defined in section 6 of the Offer.

2.4. Package — a fixed quantity of units of Mana determined by the Seller and offered for purchase at the price stated in the catalogue of packages on the Game's website.

2.5. AI agent — a software component of the Game that produces the answers of the game characters and the related in-game texts (descriptions, reactions, elements of narration) using the artificial-intelligence models of an external provider.

2.6. Order — a request placed by the User to purchase a particular Package. Each Order is assigned an order number — a unique human-readable identifier that is stated in the payment reference and in the fiscal receipt and is used when contacting support.

2.7. Contract — the licence agreement for the grant of the right to use the additional functionality of the Game, concluded between the Seller and the User by acceptance of this Offer in the manner set out in section 4.

3. Subject matter of the Contract

3.1. The Seller grants the User a simple (non-exclusive) licence — the right to use the additional functionality of the Game in the amount expressed in units of the in-game resource "Mana". The right is deemed granted from the moment the corresponding quantity of Mana is credited to the User's account and is in effect from that moment until the Mana is spent or cancelled on the grounds provided for by the Offer, but no longer than the period of existence of the Account and of the provision of the Game's service (sections 16–18).

3.2. The right to use the additional functionality of the Game is granted for personal non-commercial use within the Game and is not transferable to third parties.

3.3. The rules for using the Game as a whole (the licence to the Game, permitted conduct, moderation, blocking) are determined by the Terms of Use published at https://misteriavale.com/legal/terms/.

3.4. The Game is not gambling, a lottery or a bet; the purchase of Packages and the use of the additional functionality do not involve any possibility of winning and are not based on risk.

4. The moment of conclusion of the Contract and the method of acceptance

4.1. Acceptance of the Offer consists of a combination of the User's actions — (a) ticking the mandatory box in the purchase form, by which the User simultaneously accepts the terms of the Public Offer and of the Terms of Use and confirms that they have read and agree with the Payment and Refund Policy, and (b) payment of the Order. The acceptance of each of the said documents is recorded by a separate entry in the acceptance log stating the version of the relevant document. The Contract in respect of a particular Order is deemed concluded from the moment the bank confirms the payment.

4.2. The payment button is unavailable until the mandatory box is ticked and a valid email address for sending the fiscal receipt has been given. Under the payment button there is the line: "By paying you confirm that you have read the Personal Data Policy".

4.3. On acceptance the following are recorded: the versions of all the documents accepted (and also the versions of the Personal Data Policy and of the AI Usage Policy, the acceptance of which does not require a tick), the date and time of acceptance, the User's IP address and browser data, the source of acceptance and the order number. A snapshot of the versions of the documents is kept as part of the Order and is not altered retrospectively.

4.4. Consent to receive advertising messages is given by a separate optional tick, is not a condition of purchase and may be withdrawn at any time.

5. The moment the right is granted

5.1. The right to use the additional functionality of the Game is deemed granted from the moment the corresponding quantity of Mana is credited to the User's Account.

5.2. Mana is credited only after the bank confirms the payment (a signed notification from the bank or the result of polling the status of the Order through the bank's API). The User's return to the Game's website after payment is not in itself a ground for crediting.

5.3. If the bank's confirmation is received with a delay, Mana is credited automatically once the confirmation is received; the User need take no further action (see also section 11).

6. Legal properties of Mana

6.1. Mana has the following properties:

  1. Mana is not money, electronic currency or a means of payment.
  2. Mana is not accepted by third parties.
  3. Mana has no independent value outside the Game.
  4. Mana is not withdrawn and is not converted into property.
  5. Mana is not transferred between Accounts.
  6. Mana does not yield income.
  7. Mana is used only for the functions of the Game.
  8. The price of Packages and the cost of individual in-game actions may change.
  9. Free and paid Mana are accounted for separately.
  10. On a refund, the corresponding Mana is cancelled.
  11. On a chargeback, Mana is blocked or written off.

6.2. The purchase of a Package is not a deposit of money for safekeeping and does not create monetary obligations of the Seller to the User, save those expressly provided for by the Offer and by law (including on refunds).

7. Packages and prices

7.1. The list of available Packages, their face values (the quantity of units of Mana) and their prices in roubles are published in the catalogue of packages on the Game's website and are available to the User before the Order is placed.

7.2. Specific numerical values of prices are not fixed in the Offer: the price in force is the one stated in the catalogue of packages at the moment the Order is placed.

7.3. When an Order is placed, a snapshot of its terms is recorded: the Package selected, its face value, the price, and the versions of the applicable documents. Subsequent changes to the catalogue do not affect an Order already placed.

7.4. The price of a Package is the remuneration for the grant of the right to use the additional functionality of the Game and is stated inclusive of applicable taxes.

8. Changes in prices

8.1. Mana is spent at the in-game rates in force at the moment the in-game action is performed; the rates are set by the Seller having regard to the cost of processing requests by artificial-intelligence models and are communicated to the User in the Game's interface before the action is performed. The Seller is entitled to change the composition of the catalogue of packages, the face values and prices of Packages, and also the cost of individual in-game actions paid for in Mana. Changes are published on the Game's website and apply to Orders placed after publication and to in-game actions performed after publication; Users are notified of changes in the cost of in-game actions in the Game and on the website at least 14 calendar days before the changes take effect; changes in the cost of in-game actions are proportionate to the change in the actual cost of processing requests by artificial-intelligence models.

8.2. Changes have no retroactive effect: the terms of an Order placed earlier are determined by the snapshot recorded at the moment it was placed (clause 7.3); changes in the cost of in-game actions do not apply to actions already begun or paid for.

8.3. A User who does not agree with a change in the cost of in-game actions is entitled to refuse further use of the additional functionality and to obtain a refund of the value of unused paid Mana under the Payment and Refund Policy.

9. Payment procedure

9.1. Payment is made in roubles of the Russian Federation through the internet acquiring of the servicing bank: the Faster Payments System (SBP) and bank cards.

9.2. Payment is made on the bank's secure payment page (via a payment link). The Seller does not collect or store Users' bank card details.

9.3. In the purchase form the User states an email address for sending the fiscal receipt. That address is kept as part of the Order and is used for sending the receipt.

10. Fiscal receipts

10.1. On payment of an Order the Seller issues a fiscal receipt in accordance with the legislation of the Russian Federation on the use of cash register equipment and sends it to the email address given by the User in the purchase form.

10.2. The name of the item in the receipt is formed on the template: "Right to use the additional functionality of the game, a package of N units of Mana", where N is the face value of the Package purchased. The VAT indicator in the receipt is determined by the Seller's tax status in respect of value added tax on the date of settlement in accordance with the legislation of the Russian Federation.

10.3. The specific fiscal attributes of the settlement are determined in accordance with the legislation and the recommendations of the cash register service and the fiscal data operator.

10.4. As the right to use the additional functionality is granted at the moment Mana is credited (section 5), payment of an Order is fiscalised by a single receipt at the moment of payment with the settlement-method attribute "full settlement". By accepting the Offer the User consents to the issue of one such receipt per Order; no separate fiscal receipts are issued on the subsequent spending of Mana, since spending is the use of a right already granted.

11. Crediting and spending of Mana

11.1. Mana is credited to the Account after the bank confirms the payment (clause 5.2). Crediting is idempotent: repeated delivery of a bank notification, a repeated payment under the same Order or a repeated request via the same payment link do not lead to repeated crediting.

11.2. If no notification is received from the bank, the status of the Order is polled automatically through the bank's API, and Mana is credited without any involvement of the User. Orders with delayed confirmation are monitored by regular reconciliation.

11.3. Mana is spent on in-game actions that require the additional functionality of the Game (including the answers of the game characters produced by the AI agent). The cost of in-game actions in units of Mana is displayed in the Game and may change (section 8).

11.4. Free Mana (including starting and bonus Mana) is provided gratuitously, is accounted for separately from paid Mana and is spent first. Free Mana is not compensated in money and may be cancelled in the cases provided for by the Game's documents (including in the event of breaches, deletion of the Account, or discontinuation of the Game); the provisions of the Offer on refunds do not extend to free Mana. The terms on which free Mana is credited are published in advance and are not altered retrospectively in respect of Mana already credited.

11.5. All operations of crediting and charging Mana are recorded in the operations log. Information about the Mana balance and the purchase history with order numbers (in the Game's interface — the "order code") is available to the User in the Game.

12. Errors in the operation of the Game and of AI agents; compensation

12.1. The answers of the game characters are produced by a generative model (an AI agent) and are variable: they may contain inaccuracies, repetitions or other imperfections of a creative nature. For detail, see the AI Usage Policy: https://misteriavale.com/legal/ai/.

12.2. If, as a result of a technical failure of the Game or of an AI agent, the paid functionality was not provided or was provided with a defect (for example, Mana was charged but the result of the in-game action was not received), the Seller, on the User's request, applies one of the following methods of compensation:

  1. repeat provision of the functionality;
  2. restoration of the Mana charged;
  3. refund of the corresponding part of the money paid.

The method is determined having regard to the User's wishes; where a defect is confirmed, a refund of money may not be replaced by another method against the User's will.

12.3. To obtain compensation the User contacts support (support@misteriavale.com), quoting the order number and a description of the problem. First response within 3 working days.

13. Refunds

13.1. Refunds are made in accordance with the legislation of the Russian Federation, this section and the Payment and Refund Policy: https://misteriavale.com/legal/refund/. The User's rights as a consumer established by law are retained in full.

13.2. The main principles:

  1. If money has been debited but Mana has not been credited, Mana is credited after reconciliation or a full refund of the money is made.
  2. On double debiting, the duplicate payment is refunded and the Mana credited in excess is cancelled.
  3. Money is refunded to the original payment instrument by which payment was made; if a refund to the original payment instrument is impossible (it is closed or unavailable), the refund is made by another lawful method as agreed with the User.
  4. On a refund, the corresponding Mana is cancelled.

13.3. A full refund under an Order entails the cancellation of all the Mana of the corresponding Package and the withdrawal of access to the paid functionality opened by that purchase.

13.4. Partial refund: the value of the unused part is subject to refund — exactly the value of the Mana actually used is withheld; Mana is cancelled in proportion to the share of the sum refunded, with the quantity of Mana to be cancelled rounded down — in the User's favour; the access opened by the purchase is retained. The method of calculation with an example is set out in the Payment and Refund Policy.

13.5. If by the moment of the refund the Mana to be cancelled has already been spent, the Mana balance on the Account may become technically negative; until it is cleared, charges for paid functions are unavailable.

13.6. Functionality duly provided and actually used is not subject to refund solely because the User has changed their mind. This does not limit the User's right to a refund where the functionality was not provided, where there is a technical defect, or where a charge was made in error.

14. Chargebacks

14.1. A chargeback is a dispute raised by the User over a payment under the rules of the payment systems.

14.2. On receipt of notice of a chargeback in respect of an Order, the Mana credited under the disputed payment is blocked for the duration of the dispute; while it is blocked it cannot be spent. Mana is cancelled only upon the outcome of the dispute, if the money has in fact been returned to the payer; in that case, where the balance is insufficient, a technically negative balance arises, and access to the paid functionality opened by that purchase is withdrawn. If the chargeback is rejected, the block is lifted and the Mana is restored.

14.3. The Seller keeps and, where necessary, provides to the bank (the payment system) the following evidence: the record of acceptance with the versions of the documents, the log of Mana crediting and spending, the fiscal receipt, and the history of the Order.

14.4. The Seller recommends sending a complaint to support before applying to the bank: most problems (Mana not credited, double debiting, a defect) are resolved more quickly under sections 12–13.

15. Blocking and countering fraud

15.1. The Seller is entitled to restrict or block access to the Account in the event of a breach of the Terms of Use, including attempts to circumvent the charging of in-game actions, fraudulent payment transactions, or the use of other persons' payment instruments without the consent of their owners.

15.2. The grounds for and the procedure of blocking are determined by the Terms of Use. While the block is in force the spending of Mana is suspended; when the block is lifted the Mana balance is retained. Blocking does not mean the cancellation of all paid Mana: where a breach is confirmed, the Mana obtained as a result of the breach is cancelled; the Seller's losses are compensated by agreement of the Parties or through the courts. An unused balance paid for in good faith is retained until the dispute is resolved and is refunded in money on the User's application under the Payment and Refund Policy; nothing is deducted from the sum refunded other than the value of the Mana actually used and of the Mana obtained as a result of the breach.

16. Term of validity of Mana

16.1. The term of validity of paid Mana is not limited: Mana credited is perpetual and is retained on the Account for as long as the Account exists and the Game's service is provided — until it is spent or cancelled on the grounds provided for by the Offer (sections 13–15, 17–18).

17. The Mana balance on deletion of the Account

17.1. Deletion of the Account at the User's initiative is a withdrawal by the User from the Contract as regards the unused balance. The value of unused paid Mana is refunded in money on the User's application under the Payment and Refund Policy. Before deletion is confirmed, the User is warned about the balance and may spend it or request a refund. On deletion of the Account the Mana balance is cancelled; the right to claim a refund of the value of unused paid Mana is retained, and an application for a refund may be made after deletion of the Account as well — through support, quoting the order number. Records of orders, payments and Mana movements are retained after deletion of the Account (clause 22.2, the Personal Data Policy), which makes it possible to consider such an application. Refunds do not extend to free Mana (clause 11.4).

18. The Mana balance on discontinuation of the Game

18.1. Should a decision be taken to discontinue the Game, the following procedure applies: the Seller notifies Users at least 30 calendar days in advance — the notice is published on the website and in the Game's interface; in addition, a notice is sent to the email address given by the User at purchase or in the settings, where there is one. The notice sets out the procedure for making applications for refunds. The sale of Packages ceases from the moment the notice is published; during the notice period Mana may be spent freely.

18.2. The value of unused paid Mana is refunded in money on the User's application to the original payment instrument under the Payment and Refund Policy; the period for making an application for a refund is not limited by the date of discontinuation of the Game; refunds do not extend to free Mana.

19. Liability

19.1. The Parties bear liability in accordance with the legislation of the Russian Federation. Nothing in the Offer limits the User's rights as a consumer established by law.

19.2. The properties of the functionality provided are described in the Offer and the related documents: the service is provided with technical interruptions for maintenance (both planned and emergency), and continuous (one hundred per cent) availability of the Game is not guaranteed; the answers of the game characters are produced by a generative model, are variable and are works of fiction with possible inaccuracies (clause 12.1, the AI Usage Policy). The Game is provided exclusively for personal non-commercial use (clause 3.2).

19.3. The Seller is released from liability for non-performance or improper performance of obligations caused by circumstances of force majeure (clause 3 of Article 401 of the Civil Code of the Russian Federation), and also in cases where the non-performance was caused by the acts or omissions of the User themselves.

19.4. The User bears liability for breach of the Offer and of the Terms of Use in the manner established by law. The voluntary forms of compensation provided for by the Game's documents (repeat provision of the functionality, restoration of Mana — section 12) supplement and do not replace the User's rights established by law.

20. Complaints procedure

20.1. Complaints under the Contract are sent to the support address support@misteriavale.com, stating the order number, a description of the situation and the User's demand.

20.2. The Seller sends a first response to an enquiry within 3 working days. Complaints requiring verification of payment transactions are considered within the time limits established by the legislation on the protection of consumer rights.

20.3. Sending a complaint is a right and not an obligation of the User; this Offer does not establish a mandatory pre-trial procedure. The User is entitled to apply to a court under the rules of jurisdiction established by the legislation on the protection of consumer rights (at their own choice).

21. Procedure for amending the Offer

21.1. The Seller is entitled to publish new editions of the Offer. Each edition has a version number and an effective date and is published at the permanent URL: https://misteriavale.com/legal/offer/.

21.2. A new edition applies to Orders placed after its effective date. To Orders placed earlier, the edition whose version is recorded as part of the relevant Order on acceptance applies (clause 4.3).

21.3. Alteration of the text of the edition in force without assigning a new version number is not permitted.

22. Archive of versions and final provisions

22.1. An archive of all editions of the Offer and of the Seller's other documents is available in the documents section of the website: https://misteriavale.com/legal/.

22.2. Information about the fact and the terms of acceptance in respect of a particular Order (the versions of the documents, the date and time of acceptance) is recorded in the manner set out in clause 4.3 and is kept by the Seller as part of the Order.

22.3. The following are also an integral part of the relations between the Parties: the Terms of Use (https://misteriavale.com/legal/terms/), the Payment and Refund Policy (https://misteriavale.com/legal/refund/), the Personal Data Policy (https://misteriavale.com/legal/privacy/), and the AI Usage Policy (https://misteriavale.com/legal/ai/).

22.4. The law of the Russian Federation applies to the relations between the Parties. The choice of applicable law does not deprive the User of the protection afforded by mandatory rules of law that apply irrespective of the agreement of the parties.

22.5. The Offer is drawn up in Russian. Where a translation into another language appears, the Russian version prevails: the translation is for reference only and does not create rights or obligations of its own.
