Terms of Service

Effective September 8, 2026

Willow is a practice-management platform for psychotherapists, provided by Sulo Systems Inc. ("Sulo Systems," "we," "us"). These Terms of Service ("Terms") govern your access to and use of Willow (the "Service"). By creating an account or using the Service, you agree to these Terms.

1. Who these Terms apply to

A "Practice" is a therapy practice, clinician, or other organization that signs up for Willow. Practice staff ("Practitioners") act on behalf of their Practice. Clients of a Practice may also use Willow's client portal to book appointments, message their practitioner, sign forms, and pay invoices. These Terms apply to Practices, Practitioners, and Clients alike, except where a section says otherwise.

2. The Practice is responsible for its data

Each Practice is solely responsible for the accuracy, legality, and appropriateness of the client information, clinical notes, and other content it stores in Willow, and for its own compliance with the professional, regulatory, and privacy obligations that apply to it (including any applicable health-information-privacy law). Sulo Systems provides the software; it does not provide clinical, legal, or regulatory advice, and is not a party to the therapeutic relationship between a Practice and its Clients.

3. Accounts & acceptable use

You're responsible for keeping your login credentials confidential and for all activity under your account. You agree not to use the Service to violate any law, infringe anyone's rights, upload malicious code, or attempt to access data that doesn't belong to you or your Practice.

4. Subscriptions & payment

Practices subscribe to Willow on a recurring basis at the price shown at checkout, billed through our payment processor, Stripe. Subscriptions renew automatically until cancelled; you can cancel at any time from Settings, and access continues through the end of the paid period. Fees are non-refundable except where required by law.

Willow can optionally let a Practice connect its own Stripe account so its Clients can pay invoices online. Those payments go directly to the Practice's own Stripe account — Sulo Systems does not hold, control, or take a share of Client payments made this way, and is not responsible for a Practice's billing arrangements with its own Clients.

5. Termination

We may suspend or terminate access to the Service for a Practice that breaches these Terms, doesn't pay its subscription, or uses the Service in a way that puts other users or Sulo Systems at risk. A Practice may stop using the Service at any time by cancelling its subscription.

6. Disclaimers & limitation of liability

The Service is provided "as is," without warranties of any kind. To the maximum extent permitted by law, Sulo Systems will not be liable for indirect, incidental, or consequential damages, or for any amount exceeding the fees paid for the Service in the twelve months before the claim arose.

7. Changes to these Terms

We may update these Terms from time to time. If we make material changes, we'll provide reasonable notice (for example, by email or an in-app notice) before they take effect.

8. Governing law

These Terms are governed by the laws of the Province of Ontario and the federal laws of Canada applicable therein, without regard to conflict-of-law principles.
