MuscleClock ("the App") is an independent mobile application for iPhone and Android. This policy explains what data the App collects, how it is used, who it is shared with, and how you can control or delete it.
Used to create and sign in to your account via Firebase Authentication. We do not use it for marketing.
Muscle names, notes, tags, rest hours, exercise names, and logged attempt weights you add in the App. This data is stored so the App can show it back to you and sync it across your own devices. It is never sold.
The free version of the App shows a small banner ad served by Google AdMob. To show and measure ads, the Google Mobile Ads SDK collects your device's IP address (which can be used to estimate your general location), device and advertising identifiers (the Android advertising ID, or on iPhone the advertising identifier if you allow tracking), how you interact with ads, and diagnostic information such as crashes and performance. Details are in the "Ads and Your Choices" section below.
If you buy the one-time ad-free upgrade, RevenueCat receives a confirmation of that purchase from Apple or Google together with an anonymous, randomly generated app-user ID, so the upgrade can be recognised and restored on your devices. We do not give RevenueCat your email address or any other personal details. We never see your card or billing details; the payment is handled entirely by the App Store or Google Play.
We do not collect your precise location, contacts, photos, or microphone/camera data, and we do not run our own analytics or tracking.
If you allow notifications, the App schedules local reminders on your device that tell you when a muscle has finished recovering (for example, "Chest is recovered"). These reminders are created on your device from the rest times you set. No notification content is sent to or from any server. You can turn notifications off at any time in your device's system settings.
Your account and app data are stored using Firebase Authentication and Firebase Firestore (Google Cloud services). Firestore security rules restrict every user's data so that only that signed-in account can read or write it — no other user and no public request can access it. Data is transmitted over encrypted connections. Because these providers operate globally, your data may be processed in countries other than your own.
We do not sell your personal data.
Your data is kept for as long as your account exists. You can permanently delete your account and all associated data at any time from within the App:
Menu (⋮) → Delete account
This immediately and permanently deletes your muscles, exercises, logged attempts, and your account, and cancels any reminders scheduled on that device. This action cannot be undone.
If you cannot open the App, you can request deletion from the web instead — see How to delete your account and data. Your ad-free purchase belongs to your App Store or Google Play account and is not affected by deleting your MuscleClock account.
Depending on where you live (for example in the EEA, UK, or California) you may have the right to access, correct, delete, or export your personal data, to object to or restrict certain processing, and to withdraw consent you have given. Because the App shows you your data and lets you delete it yourself, most of this can be done in the App. For anything else, contact us using the address below and we will respond within 30 days.
The App is not directed at children under 13 and does not knowingly collect their data. If you believe a child has given us personal data, contact us and we will delete it.
If this policy changes, the "Last updated" date above will be revised and the new version will be posted to this page. We may notify you via the email address associated with your account for material changes.
