Security you can verify
Your transcripts and your inbox are the two most sensitive things you give us. Here's how we protect both.
OAuth with narrow scopes
Gmail and Outlook connect via OAuth 2.0. We request the minimum scopes needed to send on your behalf — nothing more. No passwords are ever stored, and tokens are encrypted at rest and refreshable without re-auth.
AES-256 encryption at rest
All sensitive data — OAuth tokens, transcripts in-flight, generated drafts — is encrypted with AES-256-GCM, the same standard used by banks and government agencies.
TLS 1.3 in transit
Every request to and from ReplySequence is sent over TLS 1.3. HSTS is enforced with preload so downgrade attacks are not possible.
Transcripts are not stored permanently
Transcripts are processed to generate your draft, then purged on a short retention window. We do not keep a long-term archive of what was said in your meetings, and transcripts are never used to train AI models.
SOC 2 Type II infrastructure
Hosted on Vercel and backed by Supabase (Postgres) — both SOC 2 Type II certified. You inherit that posture through us, with row-level security, automated backups, and point-in-time recovery.
Signed webhooks
All inbound webhooks (Fireflies, Granola, Zapier, Resend) are verified via HMAC-SHA256 signatures. Unsigned or tampered payloads are rejected before they reach the pipeline.
Least-privilege access
Every API endpoint enforces explicit ownership checks. You can only ever see your own meetings, drafts, and sequences — never another user's data, even by ID guessing.
Rate limiting & abuse protection
Public endpoints, webhooks, and onboarding flows are rate-limited. Stripe and Clerk handle payment and auth surfaces so card data and credentials never hit our servers.
