         <h3><img class="title" src="../shared_images/subtitles_blue_light.png"> Данные формы</h3>
 
-        <p>Form data contains information typed into web forms, like user names, addresses, phone numbers, etc., and lists them in a drop-down box on future visits.
-            Unlike the other forms of local storage, form data is not sent to the web server without specific user interaction.
-            Beginning in Android Oreo (8.0), WebView’s form data was replaced by the <a href="https://medium.com/@bherbst/getting-androids-autofill-to-work-for-you-21435debea1">Autofill service</a>.
-            As such, controls for form data no longer appear on newer Android devices.</p>
+        <p>Данные формы содержат информацию, введенную в веб-формы, например имена пользователей, адреса, номера телефонов и т.д., и доступную в раскрывающемся списке при будущих посещениях.
+            В отличие от других форм локального хранилища данные формы не отправляются на веб-сервер без специального взаимодействия с пользователем.
+            Начиная с Android Oreo (8.0), данные формы WebView были заменены на <a href="https://medium.com/@bherbst/getting-androids-autofill-to-work-for-you-21435debea1">службу автозаполнения</a>.
+            Таким образом, элементы управления данными формы больше не отображаются на новых устройствах Android.</p>
