This is a translation. If it differs from the Russian text, the Russian text prevails.
1. Parties and acceptance
LLC Vulpes Solutions Technology (the “Licensor”) grants the user the right to use the software it developed, “Didox for Bitrix24 — EDI, e-invoices and counterparties of Uzbekistan” (the “App”), under this license agreement.
The user is an organization, an individual entrepreneur or an individual who uses the App in their activity. On behalf of an organization, installation and setup are done by a representative authorized to accept these terms.
The user reads the agreement before installation. Installing the App on a Bitrix24 portal and starting to work after reading it means accepting the terms. If the terms are not acceptable, installation and use should stop. The document is available without signing in at didox-int.vulpes.pro/en/terms.
2. Subject and scope of the license
The Licensor grants a simple (non-exclusive) license to use the App within its features and the chosen plan. Exclusive rights to the App are not transferred to the user.
The user may install the client part on one Bitrix24 portal, run it in a browser, use the server part through the App interface, connect their own Didox companies, create and process documents, get details and statuses, and set up CRM fields and tabs. Loading the client part into device memory and storing it temporarily, as needed for such work, are permitted.
The user gives access to their employees within the configured portal rights. Another portal requires a separate connection. The number of Didox companies and the document types depend on the plan shown to the user before choosing it.
The permitted territory of use is the Republic of Uzbekistan, the Republic of Kazakhstan and the Russian Federation. Installation depends on the App being available in the corresponding Bitrix24 Market storefront. The App works with Uzbekistan’s document flow through Didox; placement in another country does not add exchange with that country’s local EDI operators.
3. Term and price
On first connection, a 14-day trial with the features of the “Professional” plan is provided. No fee is charged for this period. After it ends, a paid integration plan is required to continue.
- “Start” — 135,500 Uzbek soums (UZS) per Bitrix24 portal per month.
- “Professional” — 200,000 Uzbek soums (UZS) per Bitrix24 portal per month.
For Bitrix24 portals in the .ru and .рф domain zones (Russian Federation), prices are stated in Russian rubles (RUB); for other portals the currency may be agreed with the Licensor. The currency and amount are shown in the app before a request is made:
- “Start” — 1,490 Russian rubles (RUB) per Bitrix24 portal per month.
- “Professional” — 2,490 Russian rubles (RUB) per Bitrix24 portal per month.
The prices are for one month of access. Paying for 12 months at once reduces the price by 10%, for 36 months — by 20%; the discounts are the same for prices in soums and in rubles, and a total in rubles is rounded to a whole ruble. The plan contents, term, total amount and purchase method are communicated to the user before payment. Payment is made for the chosen period; access is provided after payment is confirmed. Purchase methods permitted by the rules of the relevant Bitrix24 Market storefront apply. This agreement does not allow bypassing those rules.
The right of use is valid during the trial or paid period. The end date is shown in the App. The end of a period does not mean consent to a new payment and does not create a debt for the next period. Without renewal, access to paid features is suspended.
Didox services, the Bitrix24 plan and access to Bitrix24 Market, if the portal needs it, are purchased separately and are not included in the prices above. A price change does not change the cost of an already paid period. Refunds are considered according to the purchase terms and mandatory requirements of applicable law.
4. Rights and restrictions
Rights to the App’s code, interface and own documentation remain with the Licensor. Rights to Bitrix24, Didox, E-IMZO, their marks and components belong to their respective right holders. This agreement does not grant a separate license to their products.
Without the Licensor’s separate permission, one may not distribute or sell copies of the App, sublicense it, bypass access or payment restrictions, remove copyright notices, or access other people’s portals and data. The restrictions do not cancel actions expressly permitted by mandatory rules of law.
The user keeps the rights to their documents and data. Processing them does not give the Licensor the right to dispose of document contents beyond the purposes of the App.
5. Documents and signing
Internet access, a supported Bitrix24 portal and a valid Didox account are required. The user ensures lawful access to their organization’s data, assigns employees and checks details, goods, amounts and document contents before sending or signing.
In the App version as of the date of this agreement, documents are signed in the Didox account. Built-in E-IMZO signing inside Bitrix24 is not provided yet. Connecting a company by password does not sign documents and does not replace an electronic signature. Digital signature private keys are not stored on the App server.
Statuses depend on exchange with external services and may update with a delay. In case of discrepancies, check the original document in Didox. Counterparty information does not guarantee its solvency and is not a legal opinion.
6. Data and privacy
To carry out the user’s operations, the App processes portal information, details, document data and connection credentials. Processing, protection and deletion are described in the privacy policy, available without signing in.
The user ensures the necessary grounds for transferring data of employees and counterparties. The Licensor uses data to provide features, support and security of the service within the privacy policy.
7. Support and liability
Support works Monday to Friday, 10:00–19:00 Tashkent time (UTC+5). The first response comes within four business hours. The time to fix an error depends on its cause and is clarified when you contact us. Contacts are in section 10.
Updates provided during the access period are used under this agreement unless other terms are separately agreed for a new feature. The Licensor accepts reports of failures and fixes errors in its part of the integration.
Each party is liable for its own actions and breach of obligations under applicable law. The Licensor does not control Didox, Bitrix24 or internet providers and does not guarantee their uninterrupted availability. This does not release it from liability for its own breaches or from the duty to investigate integration errors.
The Licensor does not make decisions about the contents and signing of documents for the user. No term of this agreement excludes liability that the law prohibits limiting.
8. Termination of access
The user may stop working, remove the App from the portal and contact support about ending the service and deleting data. Removing the App does not cancel operations completed in Didox and does not revoke signed documents.
In case of a breach of terms, the Licensor states the reason and the actions needed to fix it. In case of a security threat, unauthorized access or a breach of law, access may be suspended immediately with subsequent notice. Restoration of access and settlements are handled according to law.
9. Versions and disputes
This version was published on 24 October 2026. A new version is posted at the same address with its date. Changes have no retroactive effect and do not worsen the terms of a paid period without the user’s agreement, except as provided by law. If new terms must be accepted, the user reads them before they apply.
The parties first contact each other to settle disagreements. An unresolved dispute is heard by a competent court. The law of the Republic of Uzbekistan applies, preserving mandatory guarantees that cannot be excluded for the user under the law of their country.
