World of Lifting (formerly PR.O) is made by Overload Apps LLC ("we", "us", "our"). This policy explains what information the World of Lifting app and its related services (the "Service") collect, why, who we share it with, and the choices you have.
By using the Service you agree to this policy and to our Terms of Service.
World of Lifting is free. There are no ads in the app, and we don't sell your personal information.
Data from Apple Health and Health Connect is used only to show your own trends, targets and insights. It is never used for advertising or marketing, never sold, and never shared with third parties unless you choose to post it.
Your profile, posts, comments, lifts and records are visible to other World of Lifting members. Your habits, body data and health data are private unless you share them.
You can delete your account in the app at any time. Some data isn't removed automatically yet, and you can ask us by email to delete it. See Delete your account and data.

Email address and sign-in method (email and password, Google, or Apple). If you sign in with Apple and hide your email, we receive Apple's private relay address instead.
Display name and profile photo.
Body type, birthdate and preferred units (kg or lb). Your body type is shown on your profile; your birthdate isn't.
Workouts, programs, exercises, sets, reps, weights, rest times, notes and workout ratings (for example energy and focus).
Personal records, class levels (Atlas and Spartan), XP and workout counts that the app calculates from your training.
Collections and folders you create.
Habits you log or that are filled in from your phone: weight, steps, sleep, food (calories, protein, carbs, fat), caffeine, water, waist and other body measurements, resting heart rate, heart rate variability (HRV), active calories, cardio minutes, and any custom habits you create.
Your habit targets, your phase (bulking, cutting or maintaining), your goal weight and your time zone (so your weekly recap arrives on Monday morning where you live).
Height, if you enter it.
Posts you publish, including photos, workouts, records and any Habits trends you choose to share.
Comments, likes and reactions, poll votes, mentions and hashtags.
Who you follow and who follows you.
A push notification token, so we can send you notifications.
Device model, operating system, app version, language, time zone and IP address.
Crash reports and performance measurements.
Which features you use (for example "started a workout" or "opened the Habits page").
A device integrity check (Firebase App Check) that helps us block fake or modified copies of the app.
When you install or open the app, our attribution partner AppsFlyer records how you got there (for example which of our ads or links you tapped), along with device information such as your IP address and a device identifier. On Android this can include the advertising ID, which Google Analytics may also use. On iPhone, we don't access the advertising identifier (IDFA), and we don't ask to track you. On Android, you can reset or delete your advertising ID in your phone's settings.
World of Lifting no longer sells subscriptions. If you subscribed to PR.O in the past, we keep your subscription status and transaction IDs (through RevenueCat, Apple and Google) so the app can tell you how to cancel. We never receive or store your card details.
If you email us, we keep your message and the details you send us so we can help you.
We only ask for a permission when you use the feature that needs it. Every permission is optional, and you can change it later in your phone's settings.
Camera: to take a profile photo or a photo for a post, and to record videos of your sets.
Photos: to choose existing photos, and to save set videos to your photo library.
Microphone: to record sound with set videos. Set videos are saved only to your phone and are not uploaded to us.
Notifications: for rest timers, workout reminders and social notifications. You can choose which notifications you get in the app's notification settings.
Apple Health or Health Connect: see the next section.
If you connect Apple Health (iPhone) or Health Connect (Android), World of Lifting can read and write the data below. You choose exactly which types to allow, and you can change that at any time in the Health app or in Health Connect.
Data
Why we use it
Weight
Your bodyweight trend, rate of change, goal timeline and estimated maintenance calories
Steps
Your daily steps habit and target
Sleep
Your sleep habit, and how your sleep compares with your own workout performance
Nutrition: calories, protein, carbs, fat and caffeine
Your food habits and targets, and your estimated maintenance calories
Water
Your daily water habit and target
Waist measurement (iPhone only)
Your body measurement trend
Resting heart rate
Your recovery trend, compared with your own baseline and your training
Heart rate variability (HRV)
Your recovery trend, compared with your own baseline and your training
Active calories
Your daily energy trend
Workouts (exercise sessions)
Your cardio minutes habit
Distance and total calories burned (Android only)
Read together with exercise sessions so cardio minutes can be imported. These values aren't stored or shown.
So your records stay up to date across your apps, World of Lifting can save these to Apple Health or Health Connect when you log them in the app: weight, food (calories, protein, carbs and fat), caffeine, water and, on iPhone, waist measurement.
The values we import are saved to your World of Lifting account so your habits, trends and targets work across your devices. Only you can see them, unless you choose to share them (for example a Habits trend post, where showing your bodyweight is optional and off by default).
We don't use health data for advertising, marketing or data mining.
We don't sell health data.
We don't share health data with third parties, except our service providers who store and process it for us (listed below), or when you choose to post it.
We don't use health data to make decisions about credit, insurance, employment or eligibility for anything.
We don't store health data in iCloud.
Our analytics never contain your health values. They only record whether you allowed access, how many data types you allowed, and which Habits features you use.
World of Lifting's use and transfer of information received from Health Connect to any other app will adhere to the Health Connect Permissions policy, including the Limited Use requirements.
You can disconnect at any time: on iPhone, open the Health app, tap your profile picture, then Apps, then World of Lifting. On Android, open Health Connect, then App permissions, then World of Lifting. Data that was already imported stays in your account until you delete those entries or your account.
World of Lifting is a social app. Other signed-in members can see:
your display name, profile photo, body type, the date you joined, your class levels, XP, rank, workout count and pinned lifts;
your posts, comments, likes and reactions;
your place on leaderboards.
People who follow you can also see your finished workouts. Anyone with an account can follow you.
When you set an all-time record in the app, your display name and the lift may be announced to all members, including by push notification.
Your display name and profile photo are in our people search. If you make your profile private on your athlete card, you won't appear in people search.
Your habits, body measurements, birthdate, health data and notification settings are private: other members can't see or access them. The app also never shows your email address to other members. It is, however, kept in your account record, which other signed-in members' apps can technically read, and we're working on moving it into a private part of your account.
To run the app: your account, workouts, programs, habits, trends, classes, records, posts and notifications.
To keep the community safe: we automatically check posts, comments and images for harmful content (see "Service providers" below), and we act on reports.
To fix bugs and improve the app, using crash reports, performance data and feature usage.
To understand which of our own ads and links bring people to the app.
To answer your questions and support requests.
To send you emails about your account, such as password resets. We don't currently send marketing emails. If we ever do, each one will have an unsubscribe link.
To meet legal obligations and enforce our terms.
We share information only with companies that provide services to us, and only what they need to do that work:
Google Firebase and Google Cloud (USA): sign-in, database, file storage, server functions, push notifications, analytics, crash reports, performance monitoring, remote configuration and app integrity checks. Google Cloud Vision and Natural Language check images and text for harmful content.
Algolia (USA): search for people, exercises (including exercises you create) and hashtags. For people, this is your display name, profile photo address and user ID only.
AppsFlyer (Israel and USA): install attribution and app links.
RevenueCat (USA): the status of older PR.O subscriptions.
Apple and Google: sign-in with Apple or Google, app distribution, and older subscription billing.
We may also share information if the law requires it, to protect the safety of our members or the public, or as part of a merger, acquisition or sale of assets, in which case this policy continues to apply to your information.
We don't sell your personal information, and we don't share it for advertising by other companies.
Your account data is kept until you delete your account. When you delete it, we delete your data as described on our data deletion page.
Crash reports are kept for up to 90 days.
Analytics data is kept for up to 14 months.
Attribution data is kept by AppsFlyer under its own retention policy. When you delete your account, you can ask us to have AppsFlyer delete it too.
Records of older purchases are kept by Apple, Google and RevenueCat as their own policies and the law require.
We don't keep database backups. Google, which hosts our data, may keep deleted data for up to 7 days for disaster recovery, then it's permanently gone.
Wherever you live, you can:
see and correct most of your information in the app;
ask us for a copy of your personal data;
delete individual workouts, posts and comments, clear habit entries, or delete your whole account;
disconnect Apple Health or Health Connect;
turn notifications off, or choose which kinds you get;
make your profile private.
To make a request, email us from the address on your account. We may need to confirm it's you before we act. We answer within 30 days.
You also have the right to restrict or object to how we use your data, to move your data to another service, and to withdraw your consent at any time. We use your data to provide the Service you signed up for, with your consent (for health data and optional permissions), for our legitimate interests (keeping the app secure and improving it) and to meet legal obligations. You can complain to your local data protection authority.
You have the right to know what personal information we collect and how we use it, to get a copy of it, to correct it and to delete it. We won't treat you differently for using these rights. We don't sell personal information or share it for cross-context behavioral advertising.
World of Lifting is not for children. You must be at least 16 years old to use it. We don't knowingly collect personal data from anyone younger. If we learn that we have, we delete it.
We protect your information with encryption in transit, access rules that limit who can read each piece of data, and limited staff access. No service can be completely secure, so please use a strong password and keep your sign-in details private.
We are based in the United States, and our service providers may process your information in the United States and other countries. Those countries may not have the same data protection laws as yours. Where the law requires it, we rely on safeguards such as the European Commission's Standard Contractual Clauses.
The app may link to websites or services we don't run. Their privacy practices are their own, so please read their policies.
We may update this policy when the Service or the law changes. We'll change the "Last updated" date above, and for important changes we may also let you know in the app.
