sovseal bills on flat plans with fair-use ceilings — not per-operation metering, and not credits. Because the architecture is zero-knowledge, every number the billing engine sees is Layer-A metadata: operation counts, ciphertext byte totals, and seat counts. The server never needs, requests, or holds a decryption key to produce an invoice.
Pricing lives in one place. Plans, prices, seats, quotas, and the trial/grace model are documented on Usage & Billing. This page covers the billing mechanics.

​
What “flat with fair use” means

There is no balance to top up and no per-call charge. Each paid plan carries a soft monthly operations ceiling that exists to catch runaway automation, not to meter you: Crossing a ceiling starts a conversation, not an overage invoice. Local memory is never metered, throttled, or billed — it runs entirely on your device.

​
Per-seat team billing

Business (5 seats included) scales by seat at $25/month per additional seat.
  • Automatic scaling — when an admin grants access beyond the purchased seat limit, the billing engine triggers a Polar subscription seat update (PATCH /subscriptions/{id}) and the new seat is invoiced.
  • Manual adjustment — add seats from Plan (/plan) via Add Seat, which updates the Polar subscription and issues a prorated invoice.
  • Webhook syncing — seat claims (customer_seat.claimed) and revocations (customer_seat.revoked) sync back via signature-verified webhooks, keeping the database and Polar aligned.

​
What the server measures

Three Layer-A dimensions, none of which require decryption:
  1. Sync operations — count of background replicate calls against the v2-agent-state edge endpoint.
  2. Encrypted storage — sum of ciphertext bytes in public.agent_state_snapshots and the sovseal-rom bucket. The server measures envelope size, never content.
  3. Seats — active member count on Business and Enterprise.
API project sub-keys (sov_proj_, sov_live_) are unlimited on every tier and are not a billing dimension.
Cryptographic privacy guarantee — usage is computed from ciphertext size and operation metadata alone. Producing your invoice never requires access to your key or your memories.

Polar checkout

sovseal uses Polar as merchant of record for checkouts, subscriptions, seat changes, and invoices. Payment credentials never touch sovseal servers. To upgrade, downgrade, or manage invoices, open Plan (/plan) in the dashboard and choose Manage Subscription to reach the Polar customer portal.
