Privacy Policy

We save your workout data so the app works for you. We also use anonymized, aggregated workout data to train a strength model that makes better recommendations for everyone. We don’t sell your personal information. You can opt out of model training or ask us to delete your data at any time by emailing support@powerliftcalc.com.

Basic account details (like your email), the workout data you log (exercises, sets, reps, weight, RPE, timestamps, bodyweight, notes), and simple app/technical stats (for reliability and troubleshooting). We don’t collect government IDs or precise GPS location.

To run and improve the app, sync your data, provide support, keep things secure, and build features. We also use de-identified and aggregated workout data to train and evaluate our strength prediction model.

Before using workout logs for training the model, we remove direct identifiers and combine data so it can’t reasonably be linked back to you. We don’t try to re-identify you, and model outputs aren’t meant to include personal info.

You can: (1) opt out of your workout data being used (anonymously) for model training; (2) get a copy of your data; (3) correct it; or (4) ask us to delete it. Email support@powerliftcalc.com. For full account deletion steps, see the “Delete My Data” page.

We share personal data only with trusted vendors who help us run the app (under contracts that protect your information), or if required by law, or to prevent harm. We may share aggregated data that doesn’t identify you. We do not sell your personal data.

We use reasonable security measures to protect your information. No system is 100% secure, but we work hard to keep your data safe.

We keep personal data while your account is active or as needed to provide the app. We may keep de-identified, aggregated data to improve the app and our models.

PowerliftCalc isn’t for children under 13, and we don’t knowingly collect their data.

If we change this policy, we’ll post the updated version here. Questions or requests? Email support@powerliftcalc.com.
