EDITORIAL PRINCIPLES

## How we write these articles

Every guide is tested on a current iPhone running the iOS version named at the top of the page. Every cryptographic claim links to its primary source — NIST, the IETF, the Apple Platform Security guide, or the OWASP Foundation. We do not run affiliate links to competing apps and we do not run "sponsored" comparisons.

When we compare App-Vault to a competitor, we describe what the competitor actually does (from their own documentation and our own testing of their current App Store build), even when that documentation is more flattering than what we would write for them.

## How we update them

Privacy product comparisons go stale fast — apps add features, change pricing, and rewrite their privacy posture. Every article carries a visible "Updated YYYY-MM-DD" date. We review each guide at least once per quarter and rewrite the comparison tables when a major competitor ships a relevant change.
