Turn production exports into safe test data

Seeding staging with production data is the classic shortcut that turns into a breach report. Masked exports give you the same row counts, cardinality and edge cases — without a single real email address in your test database.

• ✓Deterministic hashing preserves joins between tables masked separately
• ✓Realistic shape: empty cells stay empty, formats stay consistent
• ✓Mask a fresh export any time your staging seed needs updating
