Last updated October 13, 2026. This is an English translation for convenience; the Russian version is the binding one.
1. Who we are and what this is
1.1. This document is a public offer (Articles 435 and 437 of the Civil Code of the Russian Federation) from Danil Sergeevich Kozlov, who applies the special tax regime "Professional Income Tax" (self-employed, NPD), INN 694200865411 (the "Seller"), to any person (the "Customer") to conclude an agreement for access to Ostrov Pro on the terms below.
1.2. The Customer accepts the offer by ticking the consent box on the payment page and paying (Article 438(3) of the Civil Code). From that moment the agreement is concluded.
1.3. Terms: the Service is the Ostrov apps for iPhone and Mac and Ostrov Cloud; the Account is the Customer's Ostrov account; Pro is the set of paid Service features described on the pricing page; the Period is the paid month or year; the Team is a group of Accounts whose owner has paid for team access.
2. Subject
2.1. The Seller provides the Account with access to Pro features for the paid Period, and the Customer pays for it.
2.2. What Pro includes is described on the pricing page at the moment of payment. The Service is provided as it is offered at the time of use; the Seller develops it and may change individual features without making Pro worse as a whole during a paid Period.
2.3. Plans. Ostrov Pro - Pro features with the Ostrov cloud allowance (about 12 hours of meetings a month). Ostrov Ultimate - Pro features and more: a cloud allowance of about 30 hours of meetings a month, 20 GB of cloud storage, up to 10 computers, assistant memory of up to 1000 facts. Ostrov Pro with your own model - the same Pro features without the cloud allowance: processing is done by a third-party model with the Customer's own key (YandexGPT or a compatible model); the Customer contracts with and pays the model provider directly, and the Seller is not responsible for that model's work or availability. Ostrov for teams - access for 5 to 30 members of a Team whose owner has paid: Pro features for each member, a shared cloud allowance (about 9 hours of meetings per member per month), shared boards, assignments and chat; the owner takes one of the seats. Ostrov Team+ - the same for 5 to 30 members, but with a shared cloud allowance of about 18 hours of meetings per member per month, Ultimate features for each member (up to 10 computers, 20 GB, assistant memory of up to 1000 facts) and 26 weeks of manager analytics. For more than 30 people, access is provided under a separate invoice to the company on request through support. The cloud allowance follows the plan as it stood when the paid Period began: if the Seller changes the size of the allowance, the new size applies from the Period that starts after the change.
2.4. Changing plans and seats. A new payment for the same plan extends the term from the end of the paid Period. Switching between Ostrov Pro and Ostrov Ultimate, or between Ostrov for teams and Ostrov Team+, takes effect from the moment of payment, and the unused part of the previous plan is added to the new Period, converted by the monthly price of both plans (for example, 10 days of Pro at 390 RUB a month add about 4 days of Ultimate at 990 RUB a month). A payment for any other plan takes effect from the moment of payment; the unused part of the previous plan is refunded on request under section 6. For a Team, a new payment sets the number of seats for the new Period; if there are more members than seats, new members cannot join until seats free up. An Account has one auto-renewing subscription: paying for a different plan replaces the auto-renewal of the previous one.
3. Price and payment
3.1. Current prices: Ostrov Pro · monthly - 390 RUB per month; Ostrov Pro · yearly - 3 900 RUB per year; Ostrov Ultimate · monthly - 990 RUB per month; Ostrov Ultimate · yearly - 9 900 RUB per year; Ostrov Pro with your own model · monthly - 290 RUB per month; Ostrov Pro with your own model · yearly - 2 900 RUB per year; Ostrov for teams · monthly - 290 RUB per person per month, 5 to 30 people; Ostrov for teams · yearly - 2 900 RUB per person per year, 5 to 30 people; Ostrov Team+ · monthly - 490 RUB per person per month, 5 to 30 people; Ostrov Team+ · yearly - 4 900 RUB per person per year, 5 to 30 people. Prices are in Russian rubles; VAT is not charged (the Seller is a professional income tax payer).
3.2. Payment is accepted through YooKassa (NKO YooMoney LLC) by bank card and other methods available on the YooKassa payment page. Card details are entered on the YooKassa page and are never received by the Seller.
3.3. The Seller issues the receipt (Federal Law No. 422-FZ) in "My Tax" (Moi Nalog) and sends it to the email or phone number the Customer entered on the payment page, no later than the 9th of the month following the month of payment. With auto-renewal, the receipt for each charge is sent to the same contact. If you have not received a receipt, request it through support.
4. How Pro is provided
4.1. Pro access opens automatically right after payment on all devices of your Ostrov account; there is no delivery.
4.2. If a payment went through but Pro did not turn on within an hour, write to support - we will fix it or refund the payment.
5. Auto-renewal and cancellation
5.1. By paying, the Customer agrees that YooKassa saves the payment method and that the price of the same plan (for a Team - for the same number of seats) is charged automatically at the start of each next Period (one day before the paid Period ends); if the Customer has accepted an offer under clause 5.5, it applies once on its terms. The Seller only sees the type of the payment method and the last four digits of the card (for example, "Visa •• 1234").
5.2. If a renewal charge fails, it is retried once a day later; if that also fails, the subscription ends and the saved payment method is no longer used.
5.3. The Customer may turn auto-renewal off at any time: in the Ostrov app (Settings) or on the subscription page with a code from the app. Pro remains active until the end of the paid Period; no further charges are made. The reference to the saved payment method is kept for 7 days after auto-renewal is turned off: during those days auto-renewal can be turned back on with one tap on the same page, with the same payment method; after that the reference is deleted, and auto-renewal can only be restored with a new payment. If the paid Period ended within those 7 days, after restoring the plan price is charged within half an hour and the new Period starts at the moment of payment. Deleting the Account also turns auto-renewal off. On the same page the Customer may remove the saved card at any time: it is deleted immediately, auto-renewal turns off, and Pro remains until the end of the paid Period.
5.4. The Seller may change prices. A new price applies only to charges made after the Customer is notified in the app at least 10 days in advance; if the Customer does not agree, they can turn auto-renewal off.
5.5. Offers when turning auto-renewal off. When the Customer turns auto-renewal off, the Seller may offer: (a) a 10% discount on one next renewal; (b) "three months for the price of one": the next renewal of a monthly plan charges the price of one month and extends Pro by 3 months, of a yearly plan - the price of a year and extends Pro by 15 months (3 months free); for a Team - for the same number of seats. Each offer can be accepted once for the whole life of the Account and only while auto-renewal is on; only one accepted offer is in effect at a time. An accepted offer keeps auto-renewal on and applies only to one next renewal; after that the regular price under clause 5.1 is charged. If the subscription ends before that renewal (clause 5.2, or 7 days after turning auto-renewal off under clause 5.3), the offer expires. Refunds under section 6 are calculated from the amount actually paid and the Period it paid for.
6. Refunds
6.1. Under Article 32 of the Russian Consumer Protection Law, the Customer may withdraw from the agreement at any time. The refund is the part of the price proportional to the unused full days of the paid Period.
6.2. To request a refund, write through the support form or in the app (Settings → Support) and include your account code from the app. The money is returned to the same payment method within 10 days of the request; Pro access ends on the day of the refund.
6.3. If Pro was unavailable through the Seller's fault for more than 24 hours in a row, the Seller extends Pro for that time or, at the Customer's request, refunds that part of the price.
7. Responsibility
7.1. The Seller strives to keep the Service available but does not guarantee uninterrupted operation: interruptions are possible because of maintenance, failures at hosting providers, payment and communication services, and other circumstances beyond the Seller's control.
7.2. Models process speech and text automatically and can make mistakes; the Customer checks important results. The rules of use are in the Terms of Use.
7.3. The Seller's liability is limited to the price of the current paid Period, except where the law does not allow such a limitation.
8. Personal data
8.1. How the Service handles data is described in the Privacy Policy. YooKassa processes payment data under its own rules; the Seller never receives full card numbers.
9. Term and changes
9.1. The agreement is valid while Pro is paid for. The Seller may change this offer by publishing a new version on this page; for an already paid Period, the version in force on the day of payment applies.
9.2. Disputes are first resolved through support: we reply to a claim within 10 days. If no agreement is reached, the dispute goes to court under Russian law; the Customer, as a consumer, may choose the court under the Consumer Protection Law.
