And so, is this for a regular or a Pro subscription? The reason: Pro has unlimited data. I didn’t see any info. as to a data limitation, or not, at the offer page for this offer.
Do note a “complication” for the lifetime offer: you need to submit a request at the end of 10 years, for another 10 years of coverage.
For whatever it’s worth, I’m currently (only recently) on a free 1-year offer for Windscribe, and I’ve been impressed by it (ease of installation, ease of use and behavior, and data speed) from limited use.
