Privacy Policy
Updated November 12, 2026
1. Introduction
QuantVPN explains what data we collect and keep when you use the QuantVPN browser extension, apps and Telegram bot. The extension and the bot share one account: a subscription bought in the bot also works in the extension.
2. What we do not collect
We do not track what you do online. We do not collect or store:
- your browsing history or the addresses of pages you visit;
- the content of your internet traffic;
- how much data each user transfers;
- logs of your real IP address or your IP address on the VPN server.
One exception: if a wrong sign-in code is entered in the extension, our server may write the IP address of that request to a technical log to stop code guessing.
3. What we collect and keep
3.1. Account and subscription
- Telegram ID and your Telegram username, if you have one: we use them to find your subscription.
- Referral source: the link or button that brought you to the bot.
- Subscription dates and chosen server regions.
3.2. Payment
- E-mail: needed for the receipt, passed on by the payment provider YooKassa.
- Payment ID, amount and subscription period.
Bank card details never reach us: the payment is handled by YooKassa.
3.3. Browser extension
- Device ID: a random identifier we use to limit the number of browsers per subscription (two at most).
- Sign-in token: keeps your session.
- Last activity time: updated when the extension checks your subscription or the server list.
- Connection events: when you turn the VPN on, the extension tells our server the code of the chosen server and your Device ID. We store this together with your Telegram ID and the time, to see whether new users reach their first connection and which servers are busy. These records contain no website addresses and no traffic content.
- Diagnostic events: when something breaks (a failed server switch, a proxy sign-in error, a password refresh problem) the extension sends a technical event with the type and reason of the failure, the server code, the response code of our proxy, the browser and extension version, a one-way hash of your Device ID, and the time. Such events are not created while you browse or while the connection works normally.
Your chosen server, your Smart Mode site list and other settings are stored only in your browser.
3.4. Apps for phone and computer
- A device identifier that the app reports when you add the subscription: we use it to count how many devices are connected to the subscription.
4. How we use data
We use data to:
- check your subscription;
- limit the number of devices per subscription;
- remember the server you chose;
- find and fix failures;
- understand how the service works as a whole: how many connections, how busy the servers are;
- answer support requests.
5. Who we share data with
We do not sell data and do not give it to advertisers or analytics services. The exceptions are the payment provider YooKassa (to accept payments) and cases where the law requires it. We have no history of your websites and no traffic content, so we cannot hand them over.
6. How long we keep data
We do not currently delete connection events and diagnostic events automatically. We keep subscription data while the subscription is active and afterwards so that you can renew. We keep payment data as long as accounting law requires. To delete the data linked to your account, write to support.
7. Your rights
You can:
- ask what data we keep about you;
- ask us to delete your data;
- view and remove your extension devices with the
/extension_devicescommand in the bot; - stop using the service at any time.
For all of this, contact support: @quant_vpn or support@quantvpn.app.
8. Website and cookies
The website does not use cookies or analytics counters. Fonts and images are loaded from the same server as the site itself, so no third-party service receives your address when you open a page.
9. Children
The service is not intended for children under 13. We do not knowingly collect data from children.
10. Changes to this policy
We may update this policy. The current version is always on this page. We will tell you about significant changes in the extension or in the Telegram bot.
