# Provision on Subscription Tariffs
###### Version 1.04 dated March 15, 2026

The text of this document is an integral part of the Terms of Use.

## 1. General Principles
1.1. All Tariffs provide identical functionality, except for limitations on the number of supported (active) Connected Chats.
1.2. The term "day" in the system is defined as an interval of 24 hours.
1.3. The maximum subscription period is 730 days (2 years).
1.4. Upon expiration of the subscription, access to the Application's functionality may be suspended. Data created during the period without an active subscription may not be displayed in the Application.
1.5. Notification regarding the need to renew the subscription is sent to the Administrator via the Bot or by email (depending on the authentication method) no later than 14 calendar days before its expiration.
1.6. Renewal and change of subscription plans are carried out exclusively through the Admin Panel in the "Settings > Subscription" section.
1.7. The sole method of paying remuneration to the Developer is the use of Telegram's internal currency (Telegram Stars).
1.8. The Developer is entitled to unilaterally extend the subscription period without charging additional fees (within marketing promotions or for other reasons).
1.9. The subscription remains active throughout the paid period, regardless of whether the Users and the Administrator use the Application or not.

## 2. Subscription Renewal
2.1. If the Tariff selected during payment matches the current one, it is considered a subscription renewal; otherwise, it is a change of subscription (see Section 3).
2.2. Subscription renewal is performed by shifting the expiration date of the previously paid period by the number of days specified during payment.
2.3. Upon subscription renewal, unused days of the current Tariff are preserved and added to the new period.
2.4. A discount corresponding to the selected renewal period is applied upon subscription renewal.

## 3. Change of Subscription (Modification of the Active Tariff Plan)
3.1. The Application Administrator is entitled to change the tariff plan one Day after the previous Tariff modification.
3.2. Transition to a new Tariff is performed automatically (except for the case specified in clause 3.9) after the Developer receives the processed payment data from Telegram.
3.3. Upon changing the Tariff, the restrictions of the new Tariff (maximum number of chats) apply immediately.
3.4. Transition to a Tariff with fewer chats is possible only if the number of current (active) Connected Chats in the Application does not exceed the limit of the new Tariff.
3.5. Upon changing the Tariff, the value of the unused period of the current subscription is credited towards the new tariff plan in the form of additional days in accordance with the calculation rules set forth in clauses 3.7–3.9 of this Provision.
3.6. For paid Tariffs, the base daily cost when paying for a period is determined according to the formula:

**Base Daily Cost = (Base Tariff Cost / 30) * (100% - Period Discount)**

3.7. Number of additional days:
**Number of Additional Days = (Base Daily Cost of the Current Tariff * Number of Unused Days) / Base Daily Cost of the New Tariff**

3.8. The discount rate used for calculating the Base Daily Cost is taken as follows:
-- For the current Tariff: the discount for the last paid period;
-- For the new Tariff: the discount for the selected period.

3.9. Transition to a Tariff without payment (free) is carried out only through a support request followed by manual recalculation and a refund.
3.10. All calculations are performed using rounding. A discrepancy of up to 3 (three) additional days is recognized by the Administrator and the Developer as an acceptable technical tolerance, and no claims shall be made regarding such discrepancy.
3.11. If signs of abuse of the Tariff change mechanism are detected (e.g., frequent switching between Tariffs), the Developer reserves the right to suspend the Administrator's account, cancel recalculation results, and, in exceptional cases, fully block the account without a refund (in accordance with clause 8.12 of the Terms of Use).

## 4. Use of Promo Codes
4.1. Promo codes are provided for a specific amount of Telegram Stars, which are converted into additional days according to the active Tariff. The Base Daily Cost takes into account the period discount of the paid subscription (if any).
4.2. Promo codes are not available for non-paid (free) Tariffs.
