Terms of Service
Last updated: 2026-05-27
These Terms ("Terms") govern your use of Gustavia (the "Service"), operated by Gustavia ("we", "us"). By creating an account you agree to these Terms.
1. The Service
Gustavia reads messages from accounts you connect (Gmail, Outlook, WhatsApp, SMS) and extracts appointments. We write calendar events only when you click Save. You can disconnect any provider, export your data, or delete your account at any time from /settings.
2. Your account
You must be 16 or older. You are responsible for keeping your password and 2FA secret safe. Notify us at [email protected] if you suspect your account is compromised. We may suspend or terminate accounts that violate these Terms or applicable law.
3. Acceptable use
Do not (a) reverse-engineer the Service, (b) access accounts that are not yours, (c) use the Service to harass, defraud, or send spam, (d) attempt to bypass rate limits, security controls, or tenant isolation, (e) submit content that is illegal in your jurisdiction. We may suspend accounts that violate this section without notice.
4. Data we touch
See Privacy for the full list. Short version: we read message metadata + body only for the messages your connected accounts surface to us. We encrypt the OAuth tokens we hold per-user (AES-256-GCM). We do not train AI models on your data, sell it, or share it with advertisers.
5. Subscriptions and refunds
Paid plans bill in advance. You may cancel any time; cancellation stops the next renewal but does not refund the current period. Refunds for unused time are at our discretion. We will give 30 days' notice of price changes.
6. Warranty disclaimer
THE SERVICE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT APPOINTMENT EXTRACTION WILL BE ACCURATE. ALWAYS CONFIRM EVENTS BEFORE RELYING ON THEM.
7. Liability cap
TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR AGGREGATE LIABILITY FOR ANY CLAIM ARISING OUT OF THESE TERMS OR THE SERVICE IS LIMITED TO THE GREATER OF (A) FEES YOU PAID US IN THE 12 MONTHS BEFORE THE CLAIM OR (B) ONE HUNDRED U.S. DOLLARS ($100). WE ARE NOT LIABLE FOR INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES, INCLUDING LOST PROFITS OR MISSED APPOINTMENTS.
8. Termination
You may close your account from /settings at any time. We may terminate for breach of these Terms with reasonable notice (or immediately for security risk). On termination we delete your OAuth tokens, message data, and extracted events within 30 days unless we are legally required to keep them longer.
9. Data retention
Active account: we keep your data while your account is open. Closed account: 30 days, then permanent deletion. Audit logs are retained 12 months for security investigation. You can export everything from /settings at any time.
10. Governing law and disputes
These Terms are governed by the laws of New York, USA, without regard to conflict-of-law rules. Any dispute that cannot be resolved by good-faith negotiation will be settled by binding arbitration in New York County, NY under JAMS Streamlined Arbitration Rules. Each party bears its own costs unless the arbitrator decides otherwise. You may opt out of arbitration within 30 days of signup by emailing [email protected]. Class actions are waived.
11. Changes
We may update these Terms. Material changes get 30 days' notice via email to your account address. Continued use after the effective date constitutes acceptance.
