2. Description of Service

twocal is a calendar synchronization service that connects your Google Calendar and Microsoft Calendar accounts and keeps them in sync automatically. You authorize the Service to read and write calendar events on your behalf.

3. Eligibility

You must be at least 13 years old to use the Service. By using the Service, you represent that you meet this requirement.

4. Your Account

You are responsible for maintaining the security of your account and for all activity under it. Notify us immediately at [email protected] if you suspect unauthorized access.

5. Acceptable Use

You agree not to:

• Use the Service for any unlawful purpose
• Attempt to circumvent security measures, rate limits, or usage quotas
• Reverse-engineer, scrape, or probe the Service, or supply feed URLs or other inputs intended to make the Service reach systems it is not meant to access
• Use the Service to send unsolicited calendar invitations, event content, or other communications to people who have not consented to receive them, or to facilitate spam, phishing, or harassment
• Sync, copy, or extract calendar data you do not own or are not authorized to access, or use the Service to circumvent the sharing or access controls of another person or organization
• Deliberately generate excessive event volume, sync loops, or other activity designed to exhaust the resources of the Service or of Google, Microsoft, or other connected providers
• Create accounts through automated means, or register multiple accounts to evade usage limits, quotas, or a suspension
• Use the Service to harm others or violate their privacy

We may rate-limit, throttle, suspend, or terminate any account, and pause or remove any sync configuration, to enforce these terms or to protect the Service, our users, or connected providers. Where abuse threatens the Service or third parties, or risks the standing of our connected applications with Google or Microsoft, we may act immediately and without prior notice.

6. Calendar Data

The Service accesses your calendar data solely to perform synchronization as configured by you. We do not sell, share, or use your calendar events for advertising or any purpose other than providing the Service. You can revoke access at any time by disconnecting your accounts from the Settings page or from your Google / Microsoft account permissions.

7. Health Information

The Service is not intended for use with protected health information ("PHI") as defined under the Health Insurance Portability and Accountability Act ("HIPAA") unless you have entered into a Business Associate Agreement ("BAA") with us. If you are a covered entity or business associate under HIPAA, you must not use the Service to create, receive, maintain, or transmit PHI absent a signed BAA. Executed BAAs are incorporated into and form part of these Terms.

8. Availability; Disclaimer of Warranties

We strive for high availability but do not guarantee uninterrupted access. The Service is provided "as is" and "as available." To the maximum extent permitted by law, we disclaim all warranties, express or implied, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or secure, and we are not liable for sync failures, data loss, or missed events caused by outages at Google, Microsoft, or our infrastructure.

9. Termination

You may delete your account at any time from the Settings page. Deletion takes effect after a 30-day grace period during which you can restore your account by signing back in; after that your data is permanently removed. Requesting deletion cancels any paid subscription immediately, without proration or refund for the remainder of the billing period. We reserve the right to suspend or terminate accounts that violate these Terms.

10. Limitation of Liability

To the maximum extent permitted by law: (a) twocal shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or for lost profits, revenue, or data, arising from or related to the Service, even if advised of the possibility of such damages; and (b) twocal's total aggregate liability arising from or related to the Service and these Terms, regardless of the theory of liability, shall not exceed the greater of (i) the amounts you paid us in the twelve (12) months preceding the event giving rise to the claim, or (ii) one hundred dollars ($100). These limitations apply to any Business Associate Agreement or other data protection agreement incorporated into these Terms, except to the extent such agreement expressly states otherwise.

11. Changes to Terms

We may update these Terms at any time. Continued use of the Service after changes constitutes acceptance of the new Terms. We will notify you of material changes by email.
