Coach Lucas is a personal training and nutrition companion for iPhone. This policy explains, in plain language, what the app does with your information. The short version: your data stays on your device, and we collect nothing.
Coach Lucas has no accounts, no logins, and no servers. It makes no network calls in normal use. That means:
Apple's App Store “App Privacy” label for this app is therefore “Data Not Collected.”
The health and fitness information you choose to enter or import — such as body weight, body‑fat %, lean/fat mass, workout sets (weight and reps), calorie and macro logs, meals, cardio, supplements, and any medications you log — is saved only in the app's private database on your iPhone.
Coach Lucas can, only if you choose to, read certain data from Apple Health to save you re‑typing it: your body weight, body‑composition (body‑fat %, lean/fat mass), and the calories and macronutrients you've logged in other apps. This is read‑only — the app never writes anything back to Apple Health — and it requires your explicit permission through Apple's own Health permission screen, which you can change or revoke at any time in the Health app.
Anything imported this way is stored only in the app's private database on your device, exactly like data you type in. It is not sent to us or anyone else. Because nothing is collected off your device, Apple's App Privacy label remains “Data Not Collected.”
If you use the in‑app export feature, the app bundles your data into a file that you choose to save or share (for backup or to move to another device). You can optionally protect that file with a password (AES‑256 encryption). This is a file you create and control; the app itself still contacts no server. Once you share that file somewhere, it is outside the app's control.
Coach Lucas provides general fitness and nutrition guidance and estimates (for example, calorie and macro targets calculated from standard formulas). It is not medical or nutritional advice and is not a substitute for a qualified professional. Any medication or supplement tracking is for your own logging only. Consult your healthcare provider before making significant changes to your diet, training, or medications.
Coach Lucas is intended for adults and is not directed at children under 13.
Coach Lucas does not sync or back up your data to any cloud service, and there are no plans to add it — your health data stays on your device. If you want a copy, use the app's own export, which produces an encrypted file that you create and control. Should this ever change, this policy will be updated before any such feature ships.
If this policy changes, we'll update the “Last updated” date above and revise this page.
