LangFastPro is operated by Adnovation Technologies LLC, USA. This page explains how information is handled when you read our lessons or contact us.
When you email us
We receive your email address and the information you choose to send to [email protected]. We use it to respond to questions, corrections and other requests. We retain correspondence as needed to handle your enquiry and keep a record of its resolution. Please avoid sending unnecessary personal information.
Website analytics
We use Proferex and Ahrefs Web Analytics to understand how our website is used.
Proferex records visited pages, URL parameters, referring pages and a session identifier, and may receive connection-type information. Its script stores the session identifier in your browser's local storage. A new session starts after more than 30 minutes of inactivity. Proferex blog analytics and server logs are stored in the United States for six months. Like other website infrastructure, the servers also receive technical connection information, such as your IP address.
Ahrefs collects page and referrer information, browser and device details, language, approximate location and usage events. It uses a daily identifier to count visitors. Ahrefs states that this service uses no cookies, does not store raw IP addresses and does not track visitors across days. See Ahrefs Web Analytics and its privacy policy for details.
Your choices
You can clear site data, including local storage, through your browser settings. This does not delete records already held on servers.
For privacy questions or requests about accessing, correcting or deleting information relating to you, email [email protected]. Applicable rights and exceptions depend on the law.
Other websites
Story sources and other sites we link to have their own privacy practices. Please check their policies when you visit them.
Updates
We will post changes to this policy here and update the date above.
