Score derivation
FeiLiu VPN / QuicklyVPN
Under the Default (evidence-weighted) weighting, FeiLiu VPN / QuicklyVPN scores 7.5 on the 65% of our methodology we hold evidence for, provably between 4.91 (every unmeasured dimension at its worst) and 8.05 (every one at its published maximum).
provably between 4.91 and 8.05
Weighting: Default (evidence-weighted). Weights are allocated toward what this site independently verifies. Speed and streaming are vendor-claimed rather than measured here, so they carry roughly half the weight the industry standard assigns them; that weight moves to privacy, transparency and server authenticity, all of which are checked against primary documents or our own probe network.

Floor 4.905 is the value column summed; potential 8.055 credits each unscored dimension at its ceiling instead. Renormalising the floor over the 65% that scored gives 7.55, held at or below the potential to publish 7.5.

Reading the derivation
- Measured
- We produced this number ourselves and can reproduce it.
- Documented
- Read out of a primary document: a privacy policy, an audit report, or source code.
- Vendor-claimed
- Asserted by the provider. We have not independently verified it, and the score is capped accordingly.
- No evidence
- We found nothing to score. The dimension is excluded from the weighted mean rather than counted as zero.
A ✓ is a rule we checked that found nothing wrong, for a no-logs provider that is the point, not an absence of news. A “not disclosed” line is a negative we scored and cited; a “not assessed” line is our own gap, which lowers coverage but costs the provider nothing. Every score here is a published-formula reading of the published evidence.
