Evo of Strength (EOS) is a strength-training log built to keep your data in your hands. This page explains, in plain language, what the app handles, where it lives, and the choices you have.
EOS keeps a log of your strength training — your workouts, exercises, body weight, sex (used for strength-level comparison), progress and settings. It also keeps the profile name shown on your account. This data is stored on your own device first.
EOS uses an account, so a copy of your data is also kept securely in the cloud. That is what lets you move between devices and restore everything if you change phones. Your data is never shared with anyone else, and never used for advertising.
You can sign in with an email address or with your Google account. If you sign in with Google, we also receive the name on your Google profile, which becomes your display name in EOS. We use this only to recognise you and keep your account secure — to sign you in and help you recover access. Your email, name or Google identity is never shared with anyone else, and never used for advertising.
EOS can show how your strength compares with others. To do that, your sex, body weight and your best lifts in the four main exercises (squat, bench press, deadlift and overhead press) are sent to the cloud, linked to your account. Only these figures are used for the comparison — the rest of your logbook, such as your full history, notes and other exercises, is never used for it.
To run the app and your account, EOS uses a small, deliberate set of trusted services:
As part of normal web traffic, these services may see technical details such as your IP address — the same as visiting any website. EOS uses no advertising networks and no analytics or tracking tools. We do not follow you around the web.
We do not sell your personal information, and we do not hand it to advertisers or data brokers. Full stop.
Any time, you can export a complete backup of your data from inside the app and keep it yourself.
You can remove everything in two ways: use the Delete account button inside the app, or email us at feedback@evoofstrength.com and ask us to delete your account. Requests sent by email are completed within 30 days.
Either way, your account and all of its data are erased — both on your device and in the cloud.
This is permanent and cannot be undone.
If we change how the app handles data, we will update this page. The “last updated” date at the top always tells you when it last changed.
