Privacy Policy
The short version. DTM Fitness works fully on your phone without an account. If you choose to sign in, we back up your training so you don’t lose it. We never sell your data, show ads or track you across other apps. Progress photos never leave your phone. You can delete your account and everything in it from inside the app at any time.
Who we are
DTM Fitness (“DTM”, “we”, “us”) is a strength-training app operated by DO THE MOST FITCO (Pty) Ltd, a company registered in South Africa (registration number 2026/864468/07). We are responsible for your personal information under the EU General Data Protection Regulation (GDPR) and South Africa’s Protection of Personal Information Act (POPIA). You can reach us at [email protected].
What we collect
Without an account
Everything you enter (your profile, workouts, lifts, body measurements and progress photos) is stored only on your phone. We don’t receive any of it.
If you sign in to back up
| Information | Why we use it |
|---|---|
| Your email address | To send you a sign-in code and identify your account. We don’t send marketing emails. |
| Your training profile: age, sex, height, body weight, experience, goals, training days, equipment | To back up and restore the plan the app builds for you. |
| Injuries and joints to protect, readiness check-ins | To keep your plan safe for you when it’s restored on another device. |
| Workouts, lift records, routines, weigh-ins and tape measurements | To back up your history and sync it between your devices. |
| Basic technical logs (such as IP address and time of a request) | To keep the service secure and fix problems. Kept for a short period only. |
We never upload your progress photos, your profile picture or a workout that’s still in progress. They stay on your phone.
If you use the Smart Coach
The Smart Coach is powered by artificial intelligence (AI). When you ask it a question, the app sends your question and a short summary of your training (your plan and settings, recent workouts, lift estimates, body weight, age range, equipment and any joints to protect) to our AI provider so it can answer. The summary never includes your name, email address or photos. We don’t store your conversations: they live on your screen until you close the Smart Coach. We keep a count of how many questions you ask each day, to keep the service fair and affordable. The Smart Coach is for adults only.
If you subscribe to DTM Pro
Subscriptions are bought through Apple, so we never see your card or payment details. Our subscription provider, RevenueCat, receives the purchase record from Apple (which plan, when it started and renews, and whether it’s in a trial) together with a random ID for your app, or your DTM account ID if you’re signed in, so your subscription follows you to a new phone. It never receives your name, email address or training. We keep your subscription status with your account so the app and the Smart Coach know you have DTM Pro.
Apple Health
If you switch on Apple Health (Settings > Apple Health), DTM reads your steps, sleep, resting heart rate, heart-rate variability and the workouts your phone or watch records, and saves your DTM strength workouts to Apple Health. Health data stays on your phone. It is never uploaded to our servers, never shared with the Smart Coach or anyone else, and never used for advertising. You can switch it off in the app, or remove DTM’s access in the Health app at any time.
Crash reports
If the app crashes or hits an error, it sends us a crash report so we can fix it: the error, the screen it happened on, your phone model and system version, and the app version. Crash reports never include your name, email address, IP address, photos, workouts, weights or anything else you log. They’re kept for up to 90 days.
Anonymous usage counts
The app adds one to a daily total when certain things happen, such as “onboarding finished”, “a workout was finished” or “someone trained in their second week”, so we can see what works and fix what doesn’t. A count says nothing about who you are or which phone it came from, and nothing about what you lifted or logged. You can switch it off in Settings > Anonymous usage counts.
Feedback you send
When you use Send feedback, we receive your message, the app version and your phone model. If you add your email address, we use it only to reply to you. We keep feedback for as long as it helps us improve the app, and delete it on request.
Health information and your consent
Some of what you log, like injuries and body weight, counts as health information, which the law protects more strictly. We only store it in the cloud if you tick the consent box when you sign in, and we keep a record of when you agreed and to which version of this policy. You can withdraw that consent at any time by deleting your account, and your data stays on your phone either way.
Our legal basis
We back up your data because you ask us to (performing our agreement with you), store health details on the basis of your explicit consent, and keep the service secure because we have a legitimate interest in doing so.
Who we share it with
We don’t sell or rent your information, and we don’t share it with advertisers. We use a small number of trusted service providers who process it only on our instructions:
| Provider | What they do | Where |
|---|---|---|
| Supabase | Stores your backup and runs sign-in | Frankfurt, Germany (EU) |
| Sentry | Receives crash reports so we can fix bugs | Frankfurt, Germany (EU) |
| Resend | Delivers the sign-in code email | EU (Ireland) |
| Anthropic | Provides the AI that answers Smart Coach questions. Under its commercial terms it doesn’t use this data to train its models, and it keeps it only for a limited time for safety monitoring. | United States |
| RevenueCat | Checks and manages DTM Pro subscriptions bought through Apple | United States |
| Cloudflare | Hosts this website | Global |
Your personal coach, only if you choose one
If you link to a DTM coach with their invite code (Profile → Personal coach), that coach can see your backed-up training: workouts, lift records, your plan, body weight and measurements, and the profile details that shape your plan, including any joints you’ve flagged. They can’t see your email or progress photos, and they can’t change anything. Your coach can send you short notes, which we store with your account until they or you delete them (deleting your account deletes them too), and they can see whether you’ve read them. You can unlink at any time, and they lose access immediately.
Where information is processed outside South Africa or the EU, we rely on the provider’s standard contractual safeguards. We may also disclose information if the law requires it.
How long we keep it
Your backup stays until you delete your account. When you do, your account and everything in the cloud are deleted straight away, apart from short-lived technical logs and backups that expire on their own schedule.
Security
Your data is encrypted in transit and at rest. Each person’s records are locked so that only they can read them, and our AI provider’s key lives on our server, never in the app.
Children
You can use DTM Fitness from age 14, but cloud backup and the Smart Coach are for people aged 18 and over. Under-18s keep everything on their own phone and we collect nothing from them.
Your rights
You can ask to see, correct, export or delete your information, object to how we use it, or withdraw your consent. To get a copy of everything, use Profile → Settings → Download my data. The quickest way to delete everything is Profile → Settings → Account & backup → Delete account in the app. For anything else, email [email protected] and we’ll reply within 30 days. If you’re unhappy with our answer, you can complain to your data protection authority: the Information Regulator in South Africa, or the supervisory authority where you live in the EU.
Changes
If we change this policy in a way that matters, we’ll tell you in the app before it takes effect.
