Privacy Policy

This policy explains what Calverda LLC (“we,” “us”) collects when you use Tartan Ryder, how we use it, how long we keep it, and who we share it with. Tartan Ryder is an invitation-only golf-event companion; we collect only what we need to run the events you participate in.

Who we are

What we collect

• Identity. Your name and mobile phone number, as entered by an event organizer who invites you.
• Authentication. One-time passcodes sent to your phone, and the timestamp at which you verified them. We do not store your passcode.
• Event activity.The events you participate in and the data you generate inside them — sheet entries, scores, group competition entries, side-challenge entries, bracket picks, Ryder Cup assignments, and the messages you exchange with other participants through the app.
• Notification records. Logs of the messages we sent you (in-app and SMS), their delivery status, and your preferences.
• Operational telemetry. Server-side error reports and request logs used to keep the service running. We scrub phone numbers and other sensitive fields from these reports before they reach our error-tracking provider.

We do not collect financial account information. Tartan Ryder does not take payments and does not hold any money on your behalf.

How we use it

• To authenticate you and keep your session secure.
• To run the events you join — record entries, compute pools and standings, and notify you of activity.
• To send transactional SMS and in-app notifications you have not disabled (see our SMS Disclosure).
• To diagnose and fix problems with the service.

We do not use your information to send marketing, target advertising, or train machine-learning models.

Service providers

We share information only with vendors who process it on our instructions to operate Tartan Ryder:

• Twilio Inc.— sends SMS messages and one-time passcodes on our behalf.
• Supabase Inc.— provides our database and authentication infrastructure.
• Vercel Inc.— hosts the application.
• Functional Software, Inc. (Sentry)— collects anonymized server-side error reports.

We do not sell, rent, or otherwise transfer your information to third parties for their own purposes. We may disclose information if required by law or to protect the rights and safety of participants.

SMS opt-in scope

Mobile information — your phone number, the fact and content of any SMS opt-in, and any opt-out reply — is used only to deliver messages from Tartan Ryder on behalf of Calverda LLC. It is not sold, rented, or shared with third parties for their own marketing purposes, and it is not used for any purpose other than operating the service.

How long we keep it

We retain your account, event participation records, and notification logs for up to 24 monthsafter the last event you participated in. We may revise this window from time to time; if we shorten it, the change applies to existing data on a rolling basis. You can ask us to delete your data sooner — see “Your choices” below.

Your choices

• Notification preferences. Adjust per-channel and per-category preferences in the app under Settings, or reply STOP to any SMS to opt out of all SMS.
• Access, correction, deletion. Email support@calverda.com to request a copy of your data, correct an inaccuracy, or have your account and history deleted. We respond within 30 days.

Children

Tartan Ryder is intended for adults aged 18 and over. We do not knowingly collect information from anyone under 18.

Security

We use TLS in transit, isolated production credentials, and short-lived sessions cookies. No system is perfectly secure; if you believe your account has been compromised, contact support@calverda.com immediately.

Changes to this policy

If we materially change this policy we will update the effective date above and, where appropriate, notify you in the app or by email. Continued use of Tartan Ryder after a change constitutes acceptance of the updated policy.
