Privacy Policy

SportCircuit and the SportCircuit Planner · Last updated 1 November 2026

This policy explains what personal data we collect when you use SportCircuit's website, the SportCircuit Planner (app.sportcircuit.co.uk) and SportCircuit coaching, why we collect it, who processes it for us, how Garmin Connect, Strava and AI are used, and the rights you have over your data.

1. Who we are

SportCircuit is a brand of Pulse Fifteen Ltd, a company registered in England and Wales under company number 10042256 ("we", "us", "our"). Pulse Fifteen Ltd is the data controller for the personal data described here. SportCircuit and DailyFit15 are both Pulse Fifteen products and share one account system: if you sign in to both, it is the same account. DailyFit15's own data use is set out in its privacy notice.

2. What we collect

• Account - your name and email address, from Google or Apple sign-in, or an email account.
• Your training profile - your focus (triathlon, swim, bike or run), the sports you do and how often, your ability and level, sex (optional), weight (optional), and your training numbers: FTP, threshold pace, swim pace (CSS) and threshold heart rate.
• Races and availability - your races and goals, your usual week (rest days, long-session days), holidays and trips, festive and family days, and anything you tell us when a week is written ("a busy week at work").
• Illness and injury - when you tell us you're ill or injured: what, since when, and how you're feeling, so your plan can ease off and build you back.
• Menstrual cycle information - only if you choose to give it. See section 6.
• Completed training - sessions you mark done, partly done or missed; minutes and training load; how a session went and how you felt, with your notes and effort (RPE); and activity files you upload. From an uploaded file we keep its summary (distance, time, pace, power, heart rate), our analysis against the plan and the chart data. The file itself is not kept, and the route only if you tick "keep the route".
• Garmin Connect, Strava and Wahoo data - only if you connect them. See section 4.
• Notifications - if you turn on browser notifications, your browser's push subscription for this site.
• Messages to us - support requests, review requests and requests to join coaching.
• Technical data - basic information such as browser type, app version and error logs, to keep the service running and fix problems.

3. How we use it

• to build your season around your races and write your weekly sessions at your own paces, power and zones;
• to adjust your plan for illness, injury, holidays and what you actually did, and to show how your training matched the plan and how your fitness is tracking;
• if you're coached, so your coach can plan and review your training;
• to send your planned sessions to your Garmin device and bring your completed activities back, if you connect Garmin, to bring in activities from Strava, if you connect it, and to send planned rides and runs to Wahoo and bring your workouts back, if you connect Wahoo;
• to send you notifications you've asked for, and service emails;
• to answer your messages, keep the service secure and working, and meet our legal obligations.

We use your data to provide the service you've asked for. Where we rely on your consent - your menstrual cycle information, connecting Garmin or Strava, browser notifications - you can withdraw it at any time, as described below.

4. Garmin Connect, Strava and Wahoo

Connecting Garmin is optional. If you connect your Garmin account (from your SportCircuit set-up or your DailyFit15 account):

What we receive from Garmin

• your Garmin user ID and the permissions you granted us, and access tokens that let us act for you (stored encrypted);
• activity files (FIT) and their details - sport, start time, duration, distance, heart rate, power, pace, cadence and the device used - for activities you record after you connect.

What we send to Garmin

• your planned sessions, as structured workouts with their targets, scheduled on the days in your plan, so they're on your watch or bike computer.

How Garmin data is used

• A completed activity is matched to the planned session on its day and scored against it - time in zones, heart rate, power and pace charts, and training load - so you can see how it went, and your fitness tracks what you did. An activity with nothing planned is added as an extra session.
• In DailyFit15, a day with a Garmin activity counts toward your streak.
• The route from a Garmin activity is kept for its route map unless you turn off Route maps on the Connections page - see route maps below.

Who receives Garmin data

• It is stored and processed in Microsoft Azure, our hosting provider (database, file storage and application hosting).
• If you are coached, your coach can see your sessions and their analysis.
• It is not sold, and is not shared with any other third party.

Your control

• Turn sending workouts or bringing in activities off at any time, in your set-up or account.
• Disconnect at any time. Sessions still to come are taken off your Garmin calendar, we tell Garmin to remove our access, and no more data comes through. You can also remove access in Garmin Connect under Connected Apps.
• Deleting your account disconnects Garmin in the same way.
• Activities already brought in stay part of your training history until you delete them or your account.

Strava

Connecting Strava is optional, and it is the same connection DailyFit15 uses. If you connect it:

• We receive your Strava athlete ID, access tokens that let us act for you, and - for activities you record after you connect, including ones you keep private on Strava - their details and recorded data: sport, start time, duration, distance, heart rate, power, pace, cadence and elevation.
• A completed activity is matched to the planned session on its day and scored against it, as an uploaded file is; with nothing planned it's added as an extra session, which you can pair with a planned session yourself. The same session arriving from both Garmin and Strava is counted once. The route is kept as for Garmin (see route maps).
• In DailyFit15, a day with a Strava activity counts toward your streak, and (if you choose) finished DailyFit15 workouts are posted to Strava.

Disconnect at any time from your set-up or account, or in Strava under Settings › My Apps. Activities already brought in stay part of your own training history until you delete them or your account.

Wahoo

Connecting Wahoo is optional. If you connect your Wahoo account (from Connections in SportCircuit):

• We receive your Wahoo user ID, access tokens that let us act for you (stored encrypted), and, for workouts you record after you connect, their summary and recorded file: sport, start time, duration, distance, heart rate, power, speed and cadence.
• We send your upcoming planned rides and runs, each with its intervals and targets, scheduled on their days so they're ready in the ELEMNT app and on your device. You can turn this off; workouts already sent are then removed.
• Your workouts are scored against your plan exactly as an upload is. A session arriving from more than one service is counted once. In DailyFit15, a day with a Wahoo workout counts toward your streak. The route is kept as for Garmin (see route maps).
• If you're coached, your coach sees Wahoo sessions in your plan, as they see sessions you upload.

Disconnect at any time from Connections: workouts still to come are removed, we revoke our access, and no more data comes through. Deleting your account disconnects Wahoo in the same way.

Route maps

For runs and rides that come in from Garmin, Wahoo or Strava, we keep the GPS route so the session can show it on a map. This is on unless you turn off Route maps on the Connections page. Turning it off stops routes being kept from then on; deleting a session or your account deletes its route. Routes are stored privately in Microsoft Azure and shown only with that session: to you, and to your coach if you're coached (never for a Strava activity). They are never sent to any AI service. A route can show where you live or often train, so turn it off if you'd rather not keep it.

5. AI and your plan

Your weekly sessions are written with the help of Claude, an AI model made by Anthropic. To write a week we send Claude a brief that includes:

• your sports, level and training numbers;
• your races, the phase of your season and your usual week;
• holidays, illness or injury guidance, and anything you've typed for that week;
• last week's sessions and what you marked or uploaded yourself (not anything that came from Garmin, Strava or Wahoo);
• if you've asked for it, your estimated cycle phase for each day, as described in section 6.

If you're coached, your coach can ask Claude to draft a note on a session you uploaded yourself. It sees that session's numbers and your ratings, never your notes, and never a session from Garmin, Strava or Wahoo.

We never send your name, email or contact details. Anthropic does not use this data to train its models under the terms we operate under. Text you type for your coach or a week is sent as written, so leave out anything you'd rather not share.

6. Menstrual cycle information

This is special category (health) data. We only keep it if you choose to give it and tick the consent box (UK GDPR Article 9(2)(a)). It is:

• the first day of your last period, your usual cycle and period lengths, and whether to plan around it;
• used only to shape your own training;
• stored separately from the rest of your profile;
• never shown to a coach, other users or our support staff, and never sold or shared.

When a week is written, its days are described to Claude only as estimated phases (for example "follicular"), with no name or dates, and the written sessions never mention it. You can change it any time, or remove it completely, on your set-up page. It is deleted at once, and with your account. More detail is in the cycle privacy note.

7. Who processes your data

We don't sell your personal data. We use these providers, each only for its purpose:

• Microsoft Azure - hosting, database, file storage and outgoing email.
• Anthropic - writing your weekly sessions, as described in section 5. It never receives Garmin or Strava data.
• Google and Apple - if you sign in with them.
• Garmin and Strava - if you connect them, as described in section 4.
• Your browser's push service - Google, Apple or Mozilla, depending on your browser - to deliver notifications you've turned on. It only carries the notification.
• Your coach - if you're coached, your coach sees your plan, training and notes. Never your cycle information, and never anything that came from Strava.

8. Where your data is kept

Your data is stored in Microsoft Azure's Canada Central region, encrypted in transit and at rest. Anthropic processes the briefs it receives in the United States. Where data leaves the UK we rely on safeguards recognised under UK data protection law, such as adequacy regulations or the International Data Transfer Addendum.

9. How long we keep it

We keep your account, profile and training history for as long as your account is open, so your season and fitness carry on. Your menstrual cycle information is deleted as soon as you remove it, and Garmin and Strava tokens as soon as you disconnect. When you delete your account, your data is deleted. We may keep only what we're required to keep for legal or accounting reasons, and for no longer than needed.

10. Your rights and choices

Under UK data protection law you have the right to:

• access the personal data we hold about you;
• correct it - most of it you can change yourself on your set-up page;
• delete it - your cycle information on your set-up page, a session or upload on your plan, and your whole account on the delete account page (it's the same account for SportCircuit and DailyFit15), or by emailing us;
• export it - ask us and we'll send your data in a portable format (JSON) within one month;
• withdraw consent - remove your cycle information, disconnect Garmin or Strava, or turn notifications off at any time. That doesn't affect what was done before;
• object to or restrict some processing, and complain to the Information Commissioner's Office (ico.org.uk).

To use any of these rights, email privacy@pulsefifteen.com.

11. Cookies and storage

We use only what the site needs to work: your signed-in session and a few preferences (such as km or miles), kept in your browser. The installable app keeps a copy of itself and your plan so it opens quickly. We don't use advertising or tracking cookies.

12. Children

SportCircuit isn't intended for children under 16, and we don't knowingly collect their data. If you believe a child has given us personal data, contact us and we'll delete it.

13. Changes to this policy

We'll update this page when what we do changes, and change the date at the top. If a change is significant - such as a new use of your data or a new kind of provider - we'll tell you in the app before it applies.
