To ensure system stability and cost governance, the Free Trial Tier is subject to a strict monthly AI budget of £0.50. Upgrading to the Personal Tier unlocks a soft budget of £10.00, and the Pro Tier grants a soft budget of £50.00. Soft budgets trigger administratively warning telemetries but never result in sudden hard service blocks.

Absolutely. Subscribers on paying tiers (Personal and Pro) have full access to a self-service Stripe Customer Portal accessible directly from their platform settings panel, allowing them to upgrade, downgrade, update payment methods, or cancel their plans instantly.

SymaOS connects directly to Google Calendar API to read your schedules and free slots in real-time. The planning engine operates as a deterministic scheduling allocator: it places inferred tasks, daily briefings, and prep windows strictly within your open slots, avoiding any calendar overrides.

Yes, privacy is at the core of SymaOS. In local development sandboxes and production servers, user profiles and credentials are strictly isolated via standard header-mediated cookie identity boundaries. No autonomous agent is permitted to execute write actions without your explicit approval.
