What no-logs covers
The policy is about records the VPN operator keeps. Other traces live on the device.
A no-logs VPN does not record a history of your source address, the sites you requested through the tunnel, or the contents of that traffic. RookVPN’s free and paid profiles use the same claim: the limit on the free tier is duration and how many profiles you can hold, not a different logging rule. Billing still needs an email and a payment record. Support mail is kept so a ticket can be answered. Those records are not a browsing log.
The policy does not erase what the websites you visit already store. It does not stop a browser from having cookies. It does not remove GPS from a photo you upload. It does not make a password safe because you sent it in a chat that is logged by the chat provider. It does not hide a WebRTC candidate if the browser gathers one outside the tunnel.
If you need a secret to disappear after it is read, that is a one-time link, described in the one-time secrets guide. If you need a photo without a location tag, that is the EXIF guide. If you need to know whether the tunnel is the path the browser uses, that is a leak test, not a clause in the policy.
Read the current text on the policies page. A summary in a post is not the policy.
