Privacy Policy

Last revised on October 8, 2026.

Our privacy commitment for launch

Sylvie is operated by Sylvie AI, Inc. We are building Sylvie so that, at public launch, private assistant content stays on your device or network rather than being collected or stored on Sylvie's servers.

This is our commitment for the planned public release. The current development version uses hosted services.

Essential account and service information

Our launch commitment allows for the information needed to create and administer your account: signup and contact details, messaging consent and opt-out records, and essential account-security and service-administration records. It also allows information you choose to provide when requesting support and billing information if you subscribe to a paid service. These exceptions do not authorise collecting private assistant content for analytics, advertising or AI model training.

SMS, WhatsApp and connected services involve their respective providers. Choosing those services may require them to process the information needed to deliver messages or carry out your instructions.

Phone verification at signup

We use Twilio Verify to send and check one-time SMS codes, including for people who choose WhatsApp for their assistant. Twilio receives your phone number and the code you enter to verify possession of that number. Sylvie does not store verification codes. We keep temporary verification, attempt-limit and browser-session records for up to 48 hours before routine cleanup, then retain the verification time and provider with your beta request. Cleanup may take longer during an interruption.

Password security

Passwords you choose to save for connected services are held in an encrypted vault.

Your information

We do not sell your personal information, use it for advertising, or use your content to train AI models.

You can disconnect connected accounts or request account deletion through your Sylvie settings. Contact us if you need help or have questions about data handling.

Google API services

Sylvie's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

Messaging

For consent, message frequency, carrier charges and opt-out instructions, see our SMS Terms. Reply STOP to stop messages or HELP for assistance.
