• • Official Telegram channel (@devsms_uz) — at the Administration's discretion
• • In-system notifications — at the Administration's discretion

2.4. Claiming lack of notification is not accepted as a defense. The User is independently obligated to regularly review these Terms and stay informed of updates. Continued use of the service after Terms are updated constitutes unconditional acceptance of the new terms.

2.5. These Terms constitute the sole and complete agreement between the User and DevSMS. All prior oral or written agreements are superseded.

3.1. Registration via phone number is required to use the service.

3.2. IMPORTANT: The service does not require identity documents (passport, ID card) from users. However, the Administration reserves the right to request additional identification when necessary.

3.3. The User bears full responsibility for the accuracy and correctness of all entered data.

3.4. The User is obligated to keep account access credentials (password, token, API key) confidential and not share them with third parties.

3.5. All actions performed through the User's account, including those performed by third parties, are deemed to have been performed by the User, and the User bears full responsibility.

3.6. If unauthorized access to your account is detected, immediately notify the Administration. The User remains liable for all actions until notification is received.

4.1. The service is intended exclusively for lawful purposes in accordance with the laws of the Republic of Uzbekistan.

4.2. Permitted use: verification codes (OTP), system notifications, technical alerts, service messages, and other lawful purposes.

4.3. STRICTLY PROHIBITED:

• • Sending unsolicited bulk messages (spam) without recipients' consent
• • Using the service for fraud, deception, or dissemination of false information
• • Sending offensive, threatening, defamatory, or illegal messages
• • Sending advertising messages without an approved template
• • Unauthorized sending of messages on behalf of other persons, organizations, government agencies, or brands
• • Attempting to circumvent, breach, or abuse the platform's security systems (AI moderation, rate limiting, etc.)
• • Impersonation or unauthorized use of names of financial institutions, banks, payment systems, or government agencies
• • Any messages intended to mislead, intimidate, or deceive the SMS recipient

4.4. Users who violate any of the above rules will be immediately blocked without prior notice, all funds on their balance will be confiscated, and they may be held liable in accordance with the laws of the Republic of Uzbekistan.

5.1. The User bears FULL, SOLE, AND UNLIMITED responsibility for the content of ALL SMS messages sent through the DevSMS platform.

5.2. This responsibility is unconditionally maintained in all of the following cases:

• • The message was sent intentionally
• • The message was sent unknowingly, by mistake, or due to negligence
• • The message was sent with incorrect content due to a technical error or human factor
• • The message was sent by a third party through the User's account
• • The message was sent via API, web interface, or any other method

5.3. DevSMS acts exclusively as a technical intermediary (platform). The platform provides technical infrastructure for SMS transmission and does not create, edit, or assume any obligation to approve message content.

5.4. Every SMS sent by the User, including service names used in Universal OTP templates, OTP codes, and other parameters, is under the User's personal responsibility.

5.5. Any complaints, claims, objections, or demands from SMS recipients are directed exclusively to the sender (User). DevSMS assumes no liability for such claims.

5.6. By accepting these Terms, the User assumes all legal, financial, moral, and other consequences arising from SMS messages they have sent.

5.7. Under no circumstances shall DevSMS, its management, employees, or partners be liable for the content of SMS messages sent by the User. This rule applies regardless of whether the message is lawful or unlawful.

6.1. The DevSMS platform uses an artificial intelligence (AI)-based moderation system for automatic SMS content review.

6.2. The AI moderation system is employed to protect users and ensure the platform's lawful operation; however, it does not impose any liability on DevSMS for SMS content.

6.3. PENALTY MECHANISM: If the AI moderation system determines that message content or service parameters (company name, etc.) are prohibited:

• • The SMS WILL NOT BE SENT to the recipient
• • The full message cost WILL BE DEDUCTED from the User's balance (as a penalty)
• • The deducted funds WILL NOT BE REFUNDED
• • The incident will be recorded in the security log

6.4. The User confirms full awareness of the AI moderation system's existence and unconditionally agrees to the penalty mechanism. Penalties may be applied without prior notification.

6.5. AI moderation decisions are final and review is not guaranteed. The Administration may review decisions at its discretion but is not obligated to do so.

6.6. Attempting to bypass the moderation system — including sending Universal Template texts with prohibited content through the regular SMS form — constitutes a particularly serious violation and results in additional sanctions.

6.7. Detection of prohibited content (one or more times) gives the Administration the right to IMMEDIATELY AND COMPLETELY block the User and CONFISCATE ALL funds on their balance.

6.8. Confiscated funds WILL NOT BE RETURNED UNDER ANY CIRCUMSTANCES OR FOR ANY REASON WHATSOEVER.

6.9. The moderation system is not perfect and may not detect all prohibited content. The AI moderation system's failure to flag a message does not release the User from liability. The responsibility established in Section 5 remains in full effect for every message sent.

7.1. Universal OTP templates are standard templates pre-approved by the SMS service provider (operator) that allow users to insert their company/service name and OTP verification code.

7.2. The User bears FULL RESPONSIBILITY for ANY name entered in the "company/service name" field of a Universal Template.

7.3. The following are STRICTLY PROHIBITED as company names in Universal Templates:

• • Offensive, defamatory, or immoral words
• • Names of other companies, brands, or trademarks (e.g., Uzcard, Payme, Click, Humo)
• • Names of government agencies, banks, or financial institutions (e.g., Central Bank, Tax Committee, Ministry of Foreign Affairs)
• • Any names intended for deception, fraud, or misleading
• • Any names that violate the laws of the Republic of Uzbekistan

7.4. When a prohibited company name is detected, all provisions of Section 6 (AI Moderation System and Penalties) apply in full.

7.5. The OTP code field must contain only digits (4 to 8 digits). No other characters are accepted.

8.1. DevSMS uses the platform of an SMS service provider (operator) for SMS delivery.

8.2. All SMS messages are sent through the infrastructure of the SMS service provider (operator) and are subject to its terms.

8.3. Template Approval: All SMS templates (except Universal Templates) are reviewed and approved by the SMS service provider (operator).

8.4. The template approval process may take up to 24–48 hours. Moderation is carried out on business days (Monday–Friday); Saturday and Sunday are days off.

8.5. The SMS service provider (operator) reserves the right to reject a template. Rejected templates may be revised and resubmitted.

8.6. The User is obligated to comply with all rules and restrictions established by the SMS service provider (operator).

9.1. Payment for each SMS is deducted from the balance according to the established tariff. The tariff is calculated based on the number of SMS parts.

9.2. Payment is also charged for SMS successfully transmitted to the SMS service provider (operator) but not delivered to the recipient (FAILED, REJECTED, EXPIRED). These are the terms of the SMS service provider and mobile operators; DevSMS is not responsible for non-delivery and funds are not refunded.

9.3. For SMS blocked by the AI moderation system, the full payment is deducted as a penalty and is not refundable (see Section 6).

9.4. Funds deposited to the balance are intended exclusively for service usage and are treated as prepayment.

9.5. REFUND POLICY: Deposited funds are generally NON-REFUNDABLE. Exceptions:

• • Only funds erroneously deducted due to a technical fault of the DevSMS platform
• • Only in cases confirmed by the Administration

9.6. Tariffs may change without prior notice. New tariffs apply only to SMS sent after the change.

9.7. Subscription plans. The Start plan has no mandatory subscription fee; Pro and Business are optional monthly or yearly subscriptions:

• • The plan fee is charged from the balance at the start of each period. SMS, template and device SMS prices are the same on every plan.
• • Cashback (Pro — 5%, Business — 10%) is calculated every month from that month's SMS spend and credited to the balance as a bonus at the end of the month — yearly subscriptions included; for one month it never exceeds the plan's monthly price. Voice OTP, template and device fees do not count towards cashback.
• • Plan changes (upgrades and downgrades) take effect immediately: the current plan is cancelled and the new one is bought for a full period starting today. The value of the remaining days of the current period (the day of the change counts as used) is deducted from the new plan price; any excess is returned to the balance. API keys and devices above the new plan limit (newest first) stop working — they can be deleted; the main API key always works.
• • A cancelled plan stays active until the end of the period and then returns to Start; plan fees are not refunded on cancellation.
• • If the balance is insufficient at the end of a period, plan features are kept for 72 hours. If the balance is not topped up within that time, the plan returns to Start; no data is deleted.
• • If a plan price changes, the new price applies from the next period; the current period keeps the old price.
