Independent profiles based on verifiable encryption and audit facts alongside user-reported service quality — with privacy-core dimensions firewalled out of review scores.

§1

What this page is

This page explains what IndexFair shows for encrypted cloud-storage services: verifiable security facts, user-reported sync and support quality, and which dimensions require audit evidence rather than review sentiment.

§2

What we score

v2.1 · Global · Block B · service quality · Σ 35%

Genuine user reviews aggregate across four service-quality aspects. Weights below are indicative and not yet certified in the active methodology version.

Service-quality aspect weights
AspectIndicative weightWhat it measures
Sync reliability
12%
How reliably files sync across devices — conflicts, stalled uploads, and version-history recovery as reported by users.
Support quality
8%
Response latency and resolution quality for account, billing, and data-recovery issues.
Pricing & value
8%
Clarity of plans, storage limits, and whether users feel the subscription matches the service delivered.
App UX
7%
Onboarding friction, desktop and mobile app reliability, and day-to-day usability.
Weights are PROPOSED — shown as indicative; final values will be confirmed and dated at /changelog before go-live.
§3

What we do not score from reviews

v2.1 · Global · privacy-core · Block-A only

Three privacy-core aspects are firewalled out of Block-B — they require independent audit or technical evidence, not user sentiment:

Privacy-core criteria not scored from reviews
AspectWhy not scored from reviews
Encryption architectureWhether client-side or zero-knowledge encryption is genuinely implemented must be assessed from technical documentation and audits — not inferred from reviews.
Audit independenceWhether a published security audit is genuinely independent must be read from the audit document itself, not scored from user sentiment.
Incident & breach historyDocumented breach and incident history is a verifiable factual record — shown in the profile, not scored from reviews.
§4

The factual profile

v2.1 · Global · facts · not scored

Each service profile shows verifiable facts: encryption architecture (client-side vs server-side), published independent audit history, and documented breach or incident history. These facts are shown as a factual record — they are not scored from reviews.

§5

Sources

v2.1 · Global · signals

Service-quality scores are built from genuine user reviews across multiple platforms. We retain aggregate metrics only; verbatim review text is discarded after extraction.

§6

What we do not do

  • We do not accept brand payment to alter, reorder, or suppress scores.
  • We do not surface review text verbatim — aggregate metrics only.
  • We do not promote brands by ranking position. Order is computed; placement is not for sale.
