Par Diem

Last Updated: October 12, 2026

Par Diem ("we," "us," or "our") is committed to protecting your privacy. This Privacy Policy explains what personal information we collect when you use Par Diem, how we use it, who we share it with, and what rights you have regarding your data.

1. Information We Collect

Account Information

When you create an account, we collect your email address and name. You may optionally provide a profile photo.

If you try to sign up while Par Diem is in private beta and your email address is not on our early-access list, we keep that email address, the date or dates you tried, and which sign-in method you used (email, Google or Apple), so that we can email you once when Par Diem opens. We do not use it for anything else, and we do not create an account for you.

Sign in with Apple / Google. If you choose to sign in with Apple or with Google instead of an email and password, we receive your name and email address from the provider you choose. With Apple you may choose to share a private relay email address instead of your own. Our authentication provider also records the provider's account identifier for your account and, for Google, the profile-photo link Google supplies — we do not display, download or copy your profile photo, and we do not receive your Apple or Google password.

Golf Profile and Coaching Data

To provide personalized coaching, we collect and store:

Your Handicap Index®, goal Handicap Index, starting Handicap Index, and improvement goals
Your home course and list of courses you have played or want to play
Your stated golf weaknesses, play frequency, and coaching preferences
Post-round debrief conversations, including strengths, weaknesses, and mental patterns you describe
Coaching chat conversation history
In-round notes captured during play, including associated hole numbers and timestamps
Practice plans generated for you based on your coaching profile and debrief history
AI-synthesized coaching themes and pattern analyses derived from your usage over time
Tallies and counts computed from your scorecards, debriefs and, if you connect your Handicap ID and allow score access, your USGA score history, along with short excerpts of your own debrief wording
Pre-round playbook notes and round declaration records
Caddie notebooks generated for specific courses

Trip Planning Data

When you use Par Diem's trip planning features, we collect:

Trip names, destinations, dates, and notes
Itinerary items, including tee times, accommodations, car rentals, and other activities
Participant information: names, email addresses of invited participants, and RSVP status
Budget information and cost estimates
AI-generated trip brochures and full conversation history from trip planning chats

Golf Community Data

If you use the Golf Community feature, we store:

Your golf contacts' names, email addresses, Handicap Index (for contacts you have verified) or Avg Strokes Over Par (self-entered), home courses, and any notes you add
Shared golf history you record, including rounds played together, trips taken together, and how you met

Payment Information

Payments are processed by our third-party payment provider, Stripe. We do not store your credit card number, expiration date, or CVV on our servers. We retain records of your subscription status, billing dates, and transaction references needed to manage your account and comply with financial regulations.

Affiliate Tracking Data

Par Diem participates in the CJ Affiliate Network (operated by CJ International GmbH, part of Publicis Groupe, headquartered in France). When you click a booking or affiliate link within Par Diem — currently Booking.com links in trip planning features — CJ's tracking technology (cookies and pixels) may record:

Browser and device identifiers (user-agent string, browser version, cookie IDs)
Your IP address at the time of the click
Click timestamp and the link destination
Transactional data if you complete a booking (order ID, order amount, timestamp) — used to calculate commissions owed to Par Diem

This data is collected by CJ on their own systems and is governed by CJ's Services Privacy Policy.

Par Diem receives only aggregate commission reporting from CJ. We do not receive or store your individual transactional details from Booking.com or other affiliate partners.

If you would prefer that CJ not track your clicks, you may opt out via CJ's opt-out mechanism. Contact us at hello@pardiem.com for assistance finding the current opt-out link.

If you are located in the EU or UK: CJ's data collection via affiliate cookies may constitute processing requiring your consent under GDPR. CJ is responsible for obtaining and managing that consent as the data controller for their tracking systems. You have the right to withdraw any consent you have given to CJ at any time through their opt-out mechanism noted above.

Usage Data

We collect standard technical usage data including your device type, operating system, browser, IP address, pages visited within the app, and general usage patterns. This information helps us maintain, improve, and troubleshoot the service.

Feedback and Support Communications

If you contact us via our feedback or support form, we collect the content of your message, your email address and name, and any optional device or browser context you choose to share with us.

Health and Biometric Data (Connected Apps)

Par Diem includes optional integrations with Oura Ring and Apple Health (HealthKit), built to personalize coaching. These integrations are turned off. You cannot connect an Oura or Apple Health account, and Par Diem is not reading, receiving, or storing any data from either service.

Par Diem has not launched publicly, and no health or biometric data has ever been collected from a user through these integrations.

We may turn these integrations on in a future release. If we do, this policy will be updated before that happens, describing exactly what is read and stored at that time, and your explicit opt-in will be required.

Health and biometric data from connected apps has never been used for advertising, sold to third parties, or shared beyond what is described in this policy.

On Apple Watch, Par Diem asks for workout permission only to keep the app active during a round. Par Diem does not read any health data, does not save a workout to Apple Health, and does not send health data to our servers. While a round is active, your Apple Watch may record heart rate in Apple Health as it does during any workout; Par Diem cannot see that data. This is separate from the Apple Health and Oura integrations described above.

2. How We Use Your Information

We use your information to:

Provide and operate the Par Diem service
Generate AI-powered coaching insights, trip recommendations, and course guides personalized to your golf profile
Process payments and manage your subscription or Trip Pass access
Send transactional emails (account confirmation, password reset, trip invitations, subscription receipts, and relevant product notifications)
Diagnose and fix technical issues, and improve the product based on usage patterns
Respond to your support requests and feedback
Comply with applicable legal obligations

We do not sell your personal information to third parties. We do not use your data for advertising or share it with ad networks. We do not use your personal coaching or golf data to train AI models for any purpose other than generating responses in your own session.

3. AI Processing — How Anthropic and OpenAI Are Involved

Par Diem uses Anthropic's Claude AI models to power coaching conversations, trip planning conversations, caddie notebook generation, and other AI features. When you interact with any AI feature, the relevant context — which may include your coaching profile, debrief history, trip details, course information, and your messages — is sent to Anthropic's API to generate a response. The one exception is trip brochures, which are generated using OpenAI's API instead — see below.

Anthropic processes this data to produce the AI-generated response and handles it in accordance with their own privacy and usage policies. Anthropic retains this data for up to 30 days, and it may be accessed by Anthropic for safety and security purposes during that period. We encourage you to review Anthropic's Privacy Policy to understand how they handle API data.

We limit the data sent to Anthropic to what is reasonably necessary to generate a personalized, helpful response. We do not send payment information or raw authentication credentials to Anthropic.

Because our Oura Ring and Apple Health integrations are currently turned off (see Section 1), no health or recovery data from either service is included in the context we send to Anthropic.

Anthropic's commercial Terms of Service state that they do not use API inputs or outputs to train their models by default; you can review Anthropic's Commercial Terms of Service for their current policy on this.

Trip brochures — the shareable itinerary summary generated when you tap "Generate Brochure" for a trip — are written using OpenAI's API instead of Anthropic's. To generate a brochure, Par Diem sends OpenAI the trip's name, destination, dates, budget range, and any planning notes you've added; the itinerary items saved to that trip, other than ones you have cancelled, including tee times, hotels, car rentals, and their associated notes, addresses, and price estimates; and the name of you and of any golf contacts included in the trip's roster (no Handicap Index or Personal Recreational Value is sent to OpenAI). OpenAI processes this data to generate the brochure's written content and handles it in accordance with their own API data usage policies. We encourage you to review OpenAI's Privacy Policy to understand how they handle API data.

4. Third-Party Services We Use

We share data with the following service providers as necessary to operate Par Diem:

Supabase — Database and authentication infrastructure. Your account data and all app content are stored in Supabase's managed PostgreSQL database, hosted on AWS. Row-level security is enforced so that each user's data is accessible only to them and to authorized Par Diem service operations. Supabase Privacy Policy
Apple Inc. and Google LLC — Optional sign-in providers. If you choose Sign in with Apple or Sign in with Google, that provider confirms your identity to us and shares your name and email address (with Apple, optionally a private relay address). We do not send your golf data to either provider as part of signing in. Apple Privacy Policy · Google Privacy Policy
Anthropic — AI model provider. Your coaching, trip, and chat data is sent to Anthropic's API to generate AI responses, as described in Section 3. Anthropic Privacy Policy
OpenAI — AI model provider (trip brochures only). When you generate a trip brochure, the trip's logistics, itinerary, and the names of everyone on the trip roster are sent to OpenAI's API to generate the brochure's written content, as described in Section 3. OpenAI Privacy Policy
Stripe — Payment processing. Your payment information is transmitted directly to Stripe and governed by their security standards (PCI DSS Level 1). We share only what Stripe requires to complete a transaction and manage your subscription. Stripe Privacy Policy
Resend — Transactional email delivery. Your email address is shared with Resend to deliver account and product emails on our behalf. Resend Privacy Policy
Oura and Apple Health (HealthKit) — These optional integrations are currently turned off (see Section 1). No data is currently exchanged with either service. Oura Privacy Policy · Apple Health & Privacy
Vercel — Application hosting and infrastructure. Par Diem is hosted on Vercel's platform. Your requests pass through Vercel's servers. Vercel Privacy Policy
KAYAK — Affiliate flight and car rental links. When you click on flight or car rental links within Par Diem, you are directed to KAYAK's website. Par Diem may receive an affiliate commission on bookings made through these links. We do not share your personal data with KAYAK — link clicks are the extent of the relationship. KAYAK Privacy Policy
CJ Affiliate (Commission Junction) — Affiliate network provider. When you click Booking.com hotel links within Par Diem, CJ's tracking technology records the click and any resulting commission-eligible transaction. CJ is part of Publicis Groupe and operates internationally. Par Diem receives commission reporting only — not your individual personal data.
Booking.com — Hotel booking partner. Par Diem surfaces Booking.com links in trip planning features. If you click a Booking.com link and make a reservation, Booking.com and CJ may record transaction data for commission purposes. Par Diem does not share your personal profile data with Booking.com — link clicks are the extent of the relationship. Booking.com Privacy Policy

We do not share your personal data with any other third parties except as required by law.

5. Data Retention

We retain your account and app data for as long as your account remains active. You can delete your account at any time from Settings in the iOS app or from your profile page on the web; deletion takes effect immediately. When you delete your account from the iOS app, we also ask Apple to end Par Diem's Sign in with Apple authorization for your Apple ID. When you delete your account, your personal data is deleted and identifying details are removed from any records we are required to keep — for example, billing and referral records are retained in anonymised form, and financial transaction records may be retained for up to 7 years as required by law.

Coaching conversations, debrief records, and in-round notes are retained for the lifetime of your account because they power the longitudinal coaching insights that make Par Diem useful over time. You may delete individual debriefs, notes, or trips from within the app at any time.

We are not currently collecting or retaining any Oura or Apple Health data — see Section 1.

Email addresses from sign-up attempts made during the private beta (see Section 1) are kept until we send the email telling you Par Diem has opened, and are deleted 30 days after we send it. If we have not emailed you within 24 months of your first attempt, we delete the address then. They are also deleted as soon as you create an account or are added to our early-access list, and you can ask us to remove yours earlier by emailing hello@pardiem.com.

6. Your Privacy Rights

All Users

Regardless of where you are located, you have the right to:

Access: Request a summary of the personal data we hold about you
Correct: Update inaccurate information through your account settings or by contacting us
Delete: Delete your account and associated personal data yourself at any time — iOS: Settings → Delete Account; Web: Profile → Delete Account. You may also ask us to do it for you
Opt out of AI features: Stop using AI coaching or trip planning features at any time by not interacting with those sections of the app

California Residents (CCPA / CPRA)

If you are a California resident, you have the right to:

Know what personal information we collect about you and how it is used and shared
Request deletion of your personal information
Correct inaccurate personal information
Opt out of the sale or sharing of your personal information (we do not sell or share personal information for cross-context behavioral advertising)
Limit the use of your sensitive personal information — health and biometric data from connected apps (such as Oura or Apple Health) constitutes "sensitive personal information" under CPRA. We do not collect this data; see Section 1. If we turn these integrations on, it will only ever be with your explicit opt-in and used solely to personalize your coaching features, never for advertising or profiling
Not be discriminated against for exercising any of these rights

European and UK Users (GDPR / UK GDPR)

If you are located in the European Economic Area or United Kingdom, you have additional rights under GDPR, including:

The right to data portability — receiving your data in a structured, machine-readable format
The right to restrict processing in certain circumstances
The right to object to processing based on our legitimate interests
The right to lodge a complaint with your local data protection supervisory authority

Our legal basis for processing your data is primarily the performance of our contract with you (providing the service you signed up for) and, in some cases, our legitimate interests in improving the service and maintaining security.

Special category health data: Health and biometric data from connected apps (such as readiness scores and HRV from Oura, or sleep, HRV, and resting heart rate from Apple Health) constitutes "special category" personal data under GDPR Article 9. We do not collect this data, and never have — see Section 1. If we turn these integrations on, our legal basis will be your explicit consent, given by connecting your Oura account via our OAuth authorization flow or by tapping "Connect Apple Health" in the iOS app and allowing access in Apple's permission sheet. We will ask for that consent and update this policy first.

How to Exercise Your Rights

To request access to, correction of, or deletion of your personal data, contact us at hello@pardiem.com or through our Contact page. We will respond within 30 days. We may ask you to verify your identity before processing your request.

Deletion does not require contacting us: the in-app control above performs the deletion immediately.

7. Children's Privacy

Par Diem is not directed at individuals under 18 years of age, and we do not knowingly collect personal information from anyone under 18. If we learn that we have inadvertently collected personal data from a minor, we will delete it promptly. If you believe a minor has created an account, please contact us at hello@pardiem.com.

8. Security

We implement reasonable technical and organizational measures to protect your personal information, including:

Encrypted data transmission via HTTPS for all app traffic
Row-level security on our database, restricting data access to the authenticated account owner
Server-side API calls for all AI and payment operations — sensitive keys are never exposed to the browser
OAuth access tokens for connected third-party apps (such as Oura Ring) are encrypted with AES-256-GCM before they are stored, using a key held outside the database, and are never transmitted to or accessible from the browser
Restricted access to production systems and credentials

No method of data transmission or storage is 100% secure. While we take reasonable precautions, we cannot guarantee the absolute security of your information.

9. Cookies and Tracking

Par Diem uses session cookies that are strictly necessary for authentication and maintaining your logged-in state. We do not use third-party advertising cookies, tracking pixels, or behavioral analytics cookies. We do not share browsing data with ad networks or use cookies to build advertising profiles.

When you first visit Par Diem, a cookie notice is displayed to confirm your preferences. Because we only use strictly necessary cookies, this notice is provided as a transparency measure — no consent is required for the app to function. You may dismiss the notice at any time.

Affiliate tracking cookies: When you click a Booking.com or other affiliate link within Par Diem, third-party cookies may be set by CJ Affiliate on your device to track the click for commission purposes. These cookies are set by CJ, not by Par Diem, and are governed by CJ's cookie and privacy policies. Par Diem's own cookies remain limited to strictly necessary authentication cookies as described above.

Sign in with Apple / Google: If you choose to sign in with Apple or Google, you are taken to that provider's own sign-in pages, where the provider may set its own cookies under its own policies. Those cookies are set by Apple or Google on their own pages, not by Par Diem.

10. Changes to This Privacy Policy

We may update this Privacy Policy from time to time as the product evolves. We will notify you of material changes via email or through an in-app notice before they take effect. The "Last Updated" date at the top of this page reflects the most recent revision. Your continued use of Par Diem after changes take effect constitutes acceptance of the updated policy.
