Treblew Consumer Health Data Privacy Policy

Effective Date: 15 October 2026

Treblew is operated by Jennifer Cabral ("Treblew", "we", "us", or "our").

This policy explains how Treblew collects, uses, shares and deletes "consumer health data", as Washington's My Health My Data Act, Nevada's consumer health data law and Connecticut's data privacy law use that term: information that is linked or reasonably linkable to you and identifies your past, present or future physical or mental health status. It applies to everyone whose consumer health data Treblew handles, wherever they live, and it adds to our Privacy Policy (https://treblew.com/privacy), which covers everything else.

In short

• We collect health data only to provide the features you use, or with your consent.
• We do not sell health data, use it for advertising, or share it with data brokers.
• We do not use your body, face or voice to identify you.
• You can see, delete, and withdraw consent for your health data, and appeal our answer.

1. The consumer health data we collect, and why

Depending on the features you use, Treblew collects:

• Measured summaries of your sessions: average, highest and lowest heart rate, time in each heart-rate zone, active energy, distance, elevation and steps, with the name of the device or app that measured them, kept on your iPhone. Why: to show your sessions, history and progress.
• Heart rate and energy at a moment: the heart rate measured nearest a golf shot or a practice swing, and the energy so far, kept on your iPhone. Why: to show them with that shot or swing.
• Workouts from Apple Health that you import or link: their activity, times and which workout it is, kept with your history, and their measured summary, kept on your iPhone. Why: to add them to your history when you choose to.
• What you write and record: sessions, goals, plans, notes and Coach conversations, which can reveal health information if you include it (for example an injury in a note). Why: to keep them for you and, for Coach, to answer you.
• Coach's view of your measured values, only with Coach's separate permission for them and only when your question calls for them: your iPhone sends them for that answer only, and Treblew's servers don't store them. Why: to answer your question.
• Frames from swing videos you send for analysis, which show your body: the video stays on your iPhone, and only still frames taken from it reach Treblew, deleted once analysed. Why: to analyse your swing when you ask.
• Swings and hits your Apple Watch or iPhone detected, and estimates made from them (such as tempo or energy). Why: to show your practice and sessions.
• Swing data you share with Treblew, only when you choose to, each time: the motion your watch recorded around those swings or strokes and, for a swing filmed on your iPhone, the reading of your body's position in the clip, never the video, its sound or a health value such as heart rate. Why: only to improve swing detection and tempo; kept 12 months.

Some health information is used by Treblew only on your iPhone or Apple Watch and is never sent to Treblew's servers: heart-rate series and zones read from Apple Health to show a session, your body weight (to estimate energy when nothing measured it), your date of birth (read on Apple Watch to set its heart-rate zones), the motion your watch records around swings and strokes, and swing clips filmed on your iPhone with their sound and the reading of your body's position in them (the motion and that reading only reach Treblew if you choose to share your swing data with Treblew, as above; a clip never does).

The measured summaries of your sessions, and the heart rate and energy at a shot or swing, stay on your iPhone too, in a file for each account kept out of your iPhone's backup. They reach Treblew's servers only when Coach needs them for an answer you asked for, with its permission, and are not stored there; the stored conversation keeps Coach's answer without the measured figures. Treblew's servers keep which Apple Health workout a session is, so that a new iPhone can read its values again from Apple Health (a shot's or swing's heart rate, and an Apple Watch session recorded with Save sessions off, can't be read again).

We do not create templates of your face, voice or body, and we never use images, motion or sound to identify you. The reading of your body's position in a clip measures where your joints are, frame by frame, to estimate your swing's tempo; it stays on your iPhone and is not used to identify you.

2. Where it comes from

• You: what you enter or record in Treblew.
• Your devices: your Apple Watch and iPhone, through Treblew, while you record a session.
• Apple Health, only with the permissions you give in Apple's Health settings.

We do not buy or receive health data about you from anyone else.

3. Who receives it

We do not sell consumer health data. We do not share it with data brokers, advertisers or affiliates (Treblew has none).

These service providers process it for us, only to provide the Service and under contract:

• Amazon Web Services (Singapore region): hosting, our database, and storage of swing frames and of the swing data you share with Treblew;
• OpenAI (United States): Coach and golf swing analysis, only after you allow it. Measured values reach Coach only with their own permission. OpenAI does not use what we send to train its models.

At your direction:

• Apple Health: when you turn on Save sessions, Treblew writes the sessions you record to Apple Health on your device.
• Anyone you share with: a session summary, a clip or a motion file you share goes only where you send it.

We may disclose information when the law requires it, as described in our Privacy Policy.

4. Your consent

We collect consumer health data without asking first only when it is necessary to provide what you asked for, such as recording a session you start. Otherwise we ask first:

• Apple Health: Apple's permission screen, for each kind of data;
• Coach and swing analysis: Treblew's permission before anything is sent to OpenAI, and a separate permission before Coach receives your measured values.
• Swing data you share with Treblew: asked each time, in the sheet that says what is sent; nothing is sent without your yes.

You can withdraw consent at any time, without affecting what was done before: in Apple's Health settings, in Treblew under Settings › Your data › Coach & AI, or by writing to us. Treblew then stops collecting or sharing what that consent covered.

We do not use geofencing around any health care provider.

5. Your rights

You have the right to:

• confirm whether we collect, share or sell your consumer health data, and access it, including a list of every third party and affiliate we have shared it with and how to contact them;
• withdraw consent to our collecting and sharing it;
• have it deleted. We delete it from our systems and tell our service providers to delete it too; copies in our database backups are overwritten within 7 days.

How to use them:

• Delete everything: Settings › Your data › Delete account, in the app. Your account and its data are deleted from our database straight away, and the measured values that iPhone keeps for it are removed.
• Anything else: write to privacy@treblew.com with "Consumer health data request" in the subject. We may ask you to confirm the request from the email address of your Treblew account, so that nobody else can see or delete your data.

We answer within 30 days, as our Privacy Policy says, and never later than the law allows (45 days in Washington). If we need longer, we tell you why within those days and answer within 45 more. Requests are free, up to twice a year. We will not treat you differently for using these rights.

6. Appeals

If we decline your request, in whole or in part, you can appeal: reply to our answer with "Appeal" in the subject, or write to privacy@treblew.com. We will answer within 45 days and explain our decision in writing. If we deny your appeal, you can contact the attorney general of your state, such as the Washington State Attorney General's Office, Nevada's or Connecticut's.

7. Security and retention

We protect consumer health data as described in our Privacy Policy, and limit access to it to what running the Service needs. We keep it until you delete it or your account, except swing frames, which are deleted once analysed and at the latest 30 days after you send them, Coach conversations, which are deleted 90 days after their last message, and swing data you share with Treblew, which is deleted 12 months after you share it.

8. Changes and contact

We will update this policy when what we do changes, and update its Effective Date. If a change materially affects how we use your consumer health data, we will tell you in the app first and ask for your consent where the law requires.
