Privacy promise

Your story, your control.

Pregnancy is intimate. So we wrote this in plain English. Here's exactly what we do, what we don't, and how to wipe everything in one tap.

The seven promises

Encrypted at rest + in transit

AES-256 on disk, TLS 1.3 in flight. Even our engineers can't read your chat history without a multi-step audit trail.

Stored in EU or US — your pick

Pick at signup. We use Supabase (Frankfurt or N.Virginia) — never China, never anywhere with weak data laws.

Never used to train AI models

Your messages don't make it into anyone's training data. We hold a contract with OpenAI, Anthropic, and Moonshot that explicitly excludes us.

No ads, no third-party trackers in chat

The marketing site has analytics (PostHog, Plausible). The app itself is ad-free, tracker-free.

Delete everything in one tap

Settings → Delete account. Wipes chats, journals, voice clips, photos, embeddings — irreversibly within 24 hours.

Export anytime

Settings → Export → JSON or PDF. Take your full history with you, no questions, no waiting list.

HIPAA-aligned (we're not a covered entity yet — we follow the standard)

Denny is not a medical provider, so HIPAA legally doesn't apply — but we follow its standard for storage, access logs, and breach notification. If we partner with an OB practice in v2, we'll be covered too.

The data flow — what happens when you ask Denny something

  1. 1

    You ask

    Message arrives at our edge in Frankfurt or N. Virginia, encrypted end-to-end.

  2. 2

    We classify

    Local intent router decides: knowledge / emotional / safety / urgent — without seeing your name.

  3. 3

    We retrieve

    Our knowledge base (52 trusted sources, embedded) is searched. Nothing about you is sent yet.

  4. 4

    We respond

    Anonymized prompt → LLM. Reply comes back. Your name + week + memory are stitched in *only on your device*.

  5. 5

    We forget what we don't need

    Raw photos auto-purge after 14 days. Voice clips auto-purge after 7 days. Chat history is yours forever — unless you delete it.

A note from Mikhail

My wife was the first user. So this isn't a corporate policy I copy-pasted. I built Denny to handle data the way I'd want hers handled — minimal, encrypted, and fully under your control. If anything here ever feels off, write me directly: hello@hellodenny.com.
