Terms of Service (Public Offer)

Effective date: 3 October 2026 Provider: Sherzod Maxmudov Contact: support@elchi.tech · https://elchi.tech

1. General provisions and acceptance

1.1. These Terms of Service (the "Terms") govern the use of the Elchi mobile and desktop application (the "App") and constitute a public offer under the Civil Code of the Republic of Uzbekistan.

1.2. Installing or using the App constitutes full and unconditional acceptance of these Terms. Anyone who does not agree must not use the App.

2. Description of the service

2.1. Elchi is a private, end-to-end encrypted, peer-to-peer messenger. Messages and calls are encrypted on the user's device.

2.2. The Provider operates supporting infrastructure (a relay server for offline delivery and an address-discovery service). By architecture, this infrastructure cannot read message content and cannot determine who communicates with whom.

2.3. The App has no user accounts; the user's identifier is a cryptographic key generated and held on the user's device.

2.4. The App is distributed exclusively through official application stores; the current list of official distribution channels is maintained at https://elchi.tech. Copies obtained from any other source are not provided by the Provider, may be modified or unsafe, and the Provider accepts no responsibility whatsoever for them.

3. User obligations

3.1. Key and data safety. The user is solely responsible for safekeeping the device and the identity recovery phrase. Losing both results in irreversible loss of the identity and message history — the Provider has no ability to restore them.

3.2. Lawful use. The user undertakes not to use the App for unlawful purposes, including distribution of illegal content, harassment, fraud, or infringement of others' rights. The user further undertakes to comply with all applicable laws and regulations of the country or territory in which the user resides or is located while using the App. The user is solely responsible for the content they send and for ensuring that their use of the App is lawful in their jurisdiction.

3.3. Contact verification. For sensitive communication, verifying the contact's identity (QR code or fingerprint comparison in the App) is the user's responsibility.

4. Technical limits of the Provider's capabilities

4.1. The Provider does not moderate, access, store, or restore message content; does not maintain user profiles; and keeps no communication-metadata logs.

4.2. Consequently, the Provider is unable to recover data, unlock conversations, reset identities, or identify users — including in response to users' own requests. This is not a refusal but a technical impossibility arising from the App's architecture.

5. Availability and warranties

5.1. The App is provided "as is" and "as available." The Provider aims to keep the relay and discovery infrastructure running but does not guarantee uninterrupted availability, delivery timelines, or fitness for a particular purpose.

5.2. Peer-to-peer delivery additionally depends on both parties' networks and devices.

6. Acceptable use of infrastructure

6.1. Abuse of the relay/discovery servers — flooding, denial-of-service attacks, or use of modified clients that violate protocol limits — is prohibited and may be rate-limited or blocked at the network level.

7. Intellectual property

7.1. The App, its name, logo, and brand elements are the property of the Provider.

7.2. These Terms grant the user a personal, non-exclusive, non-transferable license to use the App on their devices.

7.3. Reverse engineering is permitted only to the extent allowed by applicable law.

8. Limitation of liability

8.1. To the maximum extent permitted by law, the Provider is not liable for: indirect, incidental, or consequential damages; loss of data caused by device loss or user actions; or content exchanged between users.

8.2. The user shall indemnify and hold the Provider harmless from any third-party claims arising out of the user's use of the App or the content the user sends, including claims resulting from a violation of these Terms or of applicable law.

9. Age requirement

9.1. The user must be at least 13 years old to use the App. Where the laws of the user's country or territory of residence set a higher minimum age for using services of this kind, or for accepting these Terms without parental consent, that higher age applies. By using the App, the user represents that they meet the age requirement applicable to them.

10. Changes and termination

10.1. The Provider reserves the right to update the App and these Terms. Material changes will be announced in the App or at https://elchi.tech with a new effective date. Continued use after changes constitutes acceptance.

10.2. The user may stop using the App at any time; the in-app erase function removes all local data.

11. Governing law and disputes

11.1. These Terms are governed by the laws of the Republic of Uzbekistan, with regard, among others, to the Law "On Informatization" (11 December 2003, 560-II) and the Law "On Telecommunications" (new edition, 27 December 2024, O'RQ-1015).

11.2. Disputes shall first be resolved through negotiation.

11.3. If negotiation fails, disputes shall be referred to the competent court at the Provider's location in the Republic of Uzbekistan, unless mandatory rules of law applicable to the user provide otherwise.

11.4. If any provision of these Terms is held invalid or unenforceable, the remaining provisions remain in full force and effect.
