How we score providers
Every provider and plan gets one number from 0 to 100. It is a weighted sum over the same 5 fields, with the weights published below. No editorial adjustments, no paid placement.
What counts, and how much
| Field | Weight | Better when | Full marks between |
|---|---|---|---|
| PriceOffer level | 30% | Lower | $2 /mo – $25 /mo |
| StorageOffer level | 25% | Higher | 0.5 TB – 10 TB |
| Zero-knowledge encryptionVendor level | 20% | Higher | Yes = full, No = none |
| Version historyVendor level | 15% | Higher | 0 days – 365 days |
| Password-protected linksOffer level | 10% | Higher | Yes = full, No = none |
The formula
- Normalise. Each field is mapped to 0–1 between the two anchors above. Below the first anchor scores 0, above the second scores 1. Yes/no fields are 0 or 1; choice fields use the fixed values listed.
- Invert fields where lower is better, such as price, so 1 is always the good end.
- Weigh and sum. Multiply each normalised value by its weight, add them up, and scale to 0–100.
- Missing data counts as the midpoint, 0.5. Nobody is rewarded for leaving a field blank, and nobody is punished beyond average.
An offer's score uses its own fields. A provider's score is its best offer blended with the provider-level fields, same formula.

Where the numbers come from
Every value on this site carries the page it was read from and the date we read it. Pages are re-checked on a schedule, and any change is reviewed by a person before it goes live. If pricing or specs change, the score follows.
