DateInvite — Playful Interactive Scheduling & Invitation Engine

DateInvite is a mobile-first web invitation platform engineered to eliminate the social friction and ambiguity of asking someone out. Texting someone lacks intentionality and excitement, while enterprise calendar tools feel sterile and transactional. DateInvite introduces an asymmetric, zero-auth architecture: senders create custom invitation links in 30 seconds without creating an account, and recipients experience an animated, interactive proposal that captures concrete preferences upon acceptance.

"Asking someone out via plain text messages lacks intentionality and leads to logistical drop-off, while enterprise calendar tools feel transactional, corporate, and awkward."

Casual Texting Ambiguity

Logistical Momentum Decay: Even after an initial "yes", endless back-and-forth about day and location causes plans to drop.
Rejection Awkwardness: Direct digital invitations often create high social pressure without playful conversational release.
Lack of Intentionality: Standard chat links fail to signal care, thought, or excitement.

Platform Churn & Privacy Vulnerabilities

Registration Barriers: Legacy RSVP platforms demand email signups, passwords, and app downloads before sending.
Email Scraping Risks: Exposing a sender's private email to client-side bundles creates severe harassment and spam vectors.
Sterility of Calendars: Enterprise scheduling links (Calendly) communicate transactional meetings rather than genuine warmth.

30-Second Link Synthesis

Creator inputs recipient name, date vibe, and private notification email. System hashes an unguessable cryptographic slug (`/invite/[slug]`) and provisions Supabase record.

SECURITY AUDIT // ROW-LEVEL SECURITY & ENCRYPTION

Zero Cross-User PII Exposure Architecture

Because DateInvite operates on an open invitation URL model, creator email addresses are protected by PostgreSQL Row-Level Security policies that prevent client-side query leakage.

SUPABASE ROW-LEVEL SECURITY POLICY // SENDER PRIVACY ISOLATIONPostgreSQL / RLS

-- Enforce cryptographic invitation isolation
-- Recipient endpoints can view proposal metadata, but never creator email
CREATE POLICY "invitation_recipient_public_read" 
ON public.invitations
FOR SELECT 
TO anon 
USING (
  slug = current_setting('request.headers', true)::json->>'x-invite-slug' 
  AND status = 'active'
);

-- Creator email is restricted strictly to server-side service roles
REVOKE SELECT (creator_email) ON public.invitations FROM anon, authenticated;
