About PrinVox

PrinVox builds Margin Guard: a way for AI SaaS teams to see their real gross margin — revenue minus AI cost — per customer and plan (plus AI cost per feature), computed directly from connected data instead of a spreadsheet guess.

We show a clear, honest number. When data is incomplete, Margin Guard says so rather than filling the gap with an estimate.

PrinVox is operated by M. Amin Sayegh, trading as PrinVox, a product of AIProCraft, Chemnitz, Germany. Full provider details are in the legal notice (Impressum).

How your data is handled: Stripe is connected through Stripe Connect and used only to read revenue data. PrinVox requests Stripe’s standard Connect permission (scope read_write; Stripe offers a read-only scope only to Stripe Apps), yet its code only performs read requests and never initiates payments, payouts, transfers or refunds. The connection credential is stored encrypted. AI usage reaches PrinVox only through the private ingestion key you create yourself. Every account’s data is isolated from every other account’s, and each margin figure is computed by fixed, auditable rules from that data.
