Privacy Policy
TURN is a running coach app run by Silver Lake Analytics Pty Ltd, ABN 21 696 408 376, of Geelong, Victoria 3216, Australia ("we", "us"). This policy explains what we collect, why, who we share it with, and how you can see or delete it.
Last updated: 10 November 2026
The short version
- We collect only what the coach needs to write and adjust your plan.
- Some of it is health information (heart rate, sleep, recovery, and any pain or injury you tell us about), so we treat all of it as sensitive.
- Your coach's replies are written with help from an AI service. Your messages and the training data they rely on are sent to that service to write each reply.
- We never sell your information and never use it for advertising.
- If you connect intervals.icu, we keep maps of your routes with the start and finish removed, so your home and workplace are never stored. You can turn maps off at any time.
- You can delete your account and your data, at any time, with one button. It is gone from our database straight away.
What we collect
When you sign up:
- your email address
- your goal (for example a race, its date and distance)
- optional answers: how much you run each week, a recent race time
- your time zone, read from your browser so your plan arrives at the right hour
When you use the coach:
- the plan we write for you
- your messages to the coach, by email or in the app, and its replies
- topics you have asked the coach not to raise again
- your 1-5 ratings of the weekly email, and which links in our emails you click
- a record of when you gave or withdrew consent to AI coaching
- if you come back from a break, an injury or an illness: the pain score you log after a run (0 to 10), whether it was worse the next morning, and where you are in your return to running
If you choose to connect intervals.icu (optional, and you can disconnect at any time):
your training history: distance, duration, pace, heart rate, elevation, cadence, stride length, left/right balance and similar measurements from your runs and rides
your wellness data: sleep, heart rate variability and resting heart rate
your heart-rate zones and fitness estimates
an access token that lets us write your plan to your intervals.icu calendar
maps of your routes, so you can see where you have run and ridden. To protect your home and workplace, we remove the first and last 500 metres of every route before we store it, so where you start and finish is never kept. Your maps are visible only to you.
Connecting intervals.icu is how you agree to share this training, recovery and route data with us. You can turn route maps off at any time on the Connections page. We then stop collecting them and delete the maps we hold. Your plan keeps working without them.
If you choose to connect Garmin through Junction (optional, and you can disconnect at any time):
- your runs and other workouts: start time, sport, distance, time, average heart rate and total climb
- your sleep each night, your resting heart rate and your heart rate variability
Junction, our data partner, holds this data for us in the United States and we read it from there each morning. We keep which Junction account is yours, when your watch was last connected, and, for 42 days, a summary of each day so your coach can answer you quickly: how many runs, their distance, time and average heart rate, and your sleep, resting heart rate and heart rate variability. We do not keep your routes or second-by-second records.
If you subscribe:
- your subscription status and history. Your card details go to our payment provider, Stripe, and never reach us.
Why we collect it
- to write your training plan and adjust it from your data and your feedback
- to answer you when you talk to the coach
- to bring you back from a break or an injury safely: your running steps up only when your pain scores and running data say it is safe
- to send your plan to your watch, if you connect intervals.icu
- to show you your routes, if you keep route maps on
- to email you your plan and your weekly summary
- to manage your trial and subscription
- to understand, in aggregate, how people use the app so we can improve it
We do not use your information to train AI models, and we do not sell it or share it for advertising.
AI coaching
The coach's replies are written using Claude, an AI service from Anthropic. To write a reply, we send Anthropic your message, the relevant part of your plan and training data, and the topics you have asked the coach to avoid. Under Anthropic's commercial terms, this content is not used to train its models.
We ask for your consent to AI coaching the first time you message the coach. You can withdraw it at any time in your account. If you do, the coach stops replying to you, but your plan and emails continue.
AI transparency (Garmin and other connected devices). If you connect a Garmin or another device (through intervals.icu or Junction), your coach uses that device's data, such as your runs, sleep, resting heart rate and heart rate variability, to adjust your plan. Some of it is sent to Claude, the AI service from Anthropic, to write your coach's replies. We ask for your explicit consent before any of your data is sent to Claude (the first time you message the coach), and you can withdraw it at any time in your account: your plan carries on, without AI-written replies. We never use your data to train AI models. While you are returning from an injury, the coach's replies also use your recent pain scores and where you are in your return.
The coach is not a doctor or a physiotherapist. It does not diagnose, prescribe medication or supplements, or give weight-loss targets, and it will tell you to see a health professional when something you describe needs one.

Cookies
We use a cookie to keep you signed in, and a cookie from PostHog to count visits. We do not use advertising cookies.
Keeping it safe
Your information is held in Australia (Supabase, Sydney). Only you can read your own records through the app. The intervals.icu access token is encrypted and never sent to your browser.
How long we keep it
We keep your information while you have an account. If you start signing up but do not confirm your email, we delete your answers after 24 hours.
Deleting your data
Use Delete my data in your account. It:
- disconnects intervals.icu and revokes our access to it
- asks Junction to delete your account there and the data it holds
- cancels any subscription
- deletes your account, your plan, your messages, your training data and every other record about you in our database
It happens straight away. Copies in our backups are overwritten within 7 days.
Some records sit outside our database and are not removed by the button:
- Our sign-in service keeps a security log of sign-ins, which includes your email address.
- The services listed under "Who we share it with" keep what they received under their own terms: for example the emails Resend sent you, payment records at Stripe, and the visit counts at PostHog. To ask us to have any of these removed, email us.
Unsubscribing
Every plan and coaching email has an unsubscribe link. Unsubscribing stops those emails. We may still send emails you need about your account, such as sign-in links and payment receipts.
Your rights
You can ask to see the information we hold about you, or ask us to correct it, by emailing contact@silverlakeanalytics.com.au. We will respond within 30 days.
If you are unhappy with how we have handled your information, email us first. If we do not resolve it, you can complain to the Office of the Australian Information Commissioner at oaic.gov.au.
Age
TURN is for people aged 18 and over.
Changes
If we change this policy in a way that matters, we will email you before the change takes effect.
