What to contact us about

Use the Telegram route for educational-content questions, display problems, improvement suggestions or content-use requests. A short, specific subject helps identify the issue immediately, such as “Bond table error in Persian”. This route does not place a trade or confirm an account operation, and sending a message does not automatically carry out a financial instruction.

A reproducible technical report

Include the page address, language, device, browser and approximate time. Describe the steps, what you expected and what actually appeared. If the problem happens only after changing language or opening a menu, state that sequence. A screenshot of the affected area can help; remove personal information, unrelated tabs and account details from it first.

Questions about a lesson

Name the lesson and section, and identify the formula, term or step that is unclear. For a numerical example, include the values you used and your calculation result; this can reveal a difference in units, decimal notation or costs. Keep an educational question distinct from a request for a personalised signal or guaranteed return: the material explains analytical methods.

Accounts, access and sensitive operations

Use the site’s official buttons for sign-in and registration. For an order, balance or withdrawal question, check the status and support route in the account service itself; this education site does not display account state. Never send passwords, one-time codes, private keys or recovery phrases to explain a problem. A similar username or familiar logo alone does not verify a sender’s identity.

Republication permission and corrections

For a permission request, identify the exact article or image, publication destination, intended use and audience scope. Receipt of a message or silence is not copying permission; consult the content-rights terms. If you find a factual or translation error, identify the wording, explain the problem and, where possible, provide a primary source so the issue can be assessed.

Clear follow-up and privacy

Continue an existing issue in the same conversation so its context stays together. Add the outcome of a retest, a browser change or the time a problem stopped. Response hours and guaranteed handling times are not published here; do not rely on a messaging reply for an urgent financial position. Share additional evidence only as necessary and through a verified route.
