Gym Boss combines the flexibility of workout notes with the intelligence of a real training system — progression, AI coaching, nutrition, and cardio tracking, all in one place.
Log a workout exactly the way you'd write it down — your own shorthand, your own order, free-form text. Gym Boss reads it and turns it into structured sets, reps, and weight, without forcing you into a rigid form first.
Every confirmed set becomes part of your history. Gym Boss tracks what you lifted, when, and how it went, then tells you what to target next — a rep, a few more pounds, or simply repeat what worked. No spreadsheet, no guessing.
Ask a real question and get an answer that already accounts for your history — no re-explaining your split, your goals, or last week's session every time. Gym Boss's AI coaching reads your actual training data, not a blank chat window.
A visual map of every muscle group you've trained, strength trends over time, and the numbers that show real progress — not just a log of what happened.
Write what you ate in plain language or scan a barcode — Gym Boss estimates calories and macros and keeps a running picture of your day against your own daily targets.
Live GPS tracking for outdoor runs and walks, or log treadmill and indoor sessions manually — distance, pace, and calories, alongside your lifts.
What's trending, what's been consistent, and where real progress is happening — summarized automatically, not buried in a log.
Download Gym Boss and start training with a system that actually knows what you did.

We may request access to your device's camera and photo library. Camera access is used to scan food barcodes and, if you choose, to photograph a meal for a Premium photo estimate. Photo library access is used only for images you explicitly select, such as a meal photo or a shareable cardio route card. We never browse, scan, or upload your photo library in the background — only the specific images you choose in the moment.
Photo estimates are a Premium feature you start deliberately. When you take or select a meal photo and request an estimate, that image is sent from your device to our servers and then on to our AI provider, OpenAI, which analyzes it and returns an estimated list of foods with calories and macros.
We do not store the photo itself. The image is passed through for analysis and is not written to any photo storage, and it is never attached to your workout logs, food history, or profile.
What we hold on to is the text estimate that comes back, and only for as long as it is useful to you. If you save the estimate, it becomes ordinary food entries that you own and can edit or delete, and the estimate text is discarded in the same moment. If you don't save it, it is cleared automatically — within about 25 hours at the outside. Alongside it we briefly keep a one-way fingerprint of the image, so that retrying a request cannot charge you twice or create a duplicate entry. That fingerprint cannot be turned back into your photo, and it is discarded at the same moment as the estimate text.
What remains afterwards is a small technical record of the request itself — when it happened, whether it succeeded, and what it cost us to run — with nothing derived from the image in it. That record is kept while your account exists and is removed when you delete your account.
Under OpenAI's API terms, content sent through the API is not used to train its models. OpenAI does, however, retain API request data for a limited period — currently up to 30 days — for abuse monitoring under its own policies, so we cannot promise that your photo is discarded the instant it is analyzed. If you would rather no image ever leave your device, simply don't use photo estimates — every nutrition feature in Gym Boss remains available through barcode scanning, search, and text entry.
We may request access or permission to track location-based information from your mobile device, either continuously (in the background) or while you are actively using the application. This data is specifically collected to track your cardio routes, distance, and pace, even when your device is locked or the app is minimized.
To provide our core features, we collect information you voluntarily provide, including account details, workout logs, and nutrition history. You may permanently delete your account and all associated personal data at any time directly within the application's settings menu.
When you use "Ask Gym Boss" or get a nutrition estimate, the text of your workout notes, food notes, or questions is sent to our AI provider, OpenAI, to generate a response. If you request a meal photo estimate, the photo you selected is sent as well. We do not send your email address, precise identity, or payment information to OpenAI. See AI Usage for more detail.
Gym Boss uses Sentry, a crash and error reporting service, to help us detect and fix app crashes and errors. Crash reports may include device and app state information at the time of the crash, but are not linked to your name, email address, or account identity, and are never used for advertising or tracking.
We use PostHog, a product analytics service, to understand how users interact with Gym Boss and to improve app performance and features. We may collect product interaction information such as whether certain features are used, app version information, and performance timing data. Gym Boss may associate these analytics events with an internal user identifier.
We do not send workout notes, AI conversations, nutrition descriptions, bodyweight values, exercise weights or repetitions, names, or email addresses to PostHog for product analytics.
We do not use PostHog data for cross-app advertising or tracking.
If you subscribe to Gym Boss Premium, your purchase is processed by Apple or Google directly — we never see or store your card number. Your subscription status is shared with our payments partner, RevenueCat, so the app can unlock Premium features on your account.
We keep your data for as long as your account is active. Deleting your account through the app removes your profile, workouts, food entries, weigh-ins, and saved AI conversations from our live database. Routine database backups may retain deleted data for a limited additional period before they are cycled out.
Gym Boss is not directed to children under 13, and we do not knowingly collect personal information from anyone under 13. If we become aware that we have collected personal information from a child under 13, we will delete it. Contact us at support@gymbossnotes.com if you believe we have inadvertently collected such information.

Gym Boss is a personal fitness, nutrition, and cardio tracking app. You must be able to form a binding contract to use it, and you're responsible for keeping your account credentials secure. You agree not to misuse the app — including attempting to access another user's data, disrupting the service, or using it for any unlawful purpose.
You must be at least 13 years old to use Gym Boss. If you are under the age of majority in your jurisdiction, you may only use Gym Boss with a parent or guardian's involvement.
Gym Boss Premium is an auto-renewing subscription billed through the Apple App Store or Google Play. It renews automatically at the end of each billing period unless you cancel at least 24 hours before renewal, through your Apple ID or Google Play account settings — we cannot cancel or refund a subscription on your behalf. Pricing and duration (monthly or annual) are shown before purchase.
You own the workout notes, food entries, and other content you create in Gym Boss. You grant us the limited right to store and process that content in order to provide the app's features, including sending relevant text — and, for photo estimates, a meal photo you choose to submit — to our AI provider as described in our Privacy Policy and AI Usage page.
Gym Boss, including anything generated by its AI features, provides general fitness and nutrition information for informational purposes only. It is not medical, dietary, or professional advice, and does not create a doctor-patient, dietitian-patient, or trainer-client relationship. Consult a qualified professional before making significant changes to your training, diet, or health routine, especially if you have an injury, a medical condition, or are pregnant.
Gym Boss is provided "as is," without warranties of any kind. To the fullest extent permitted by law, we are not liable for any indirect, incidental, or consequential damages arising from your use of the app.
You and Gym Boss agree to resolve any dispute arising from these Terms or your use of the app through binding individual arbitration under the Federal Arbitration Act, rather than in court, except that either party may bring a qualifying claim in small claims court. Any arbitration will proceed on an individual basis only — not as a class, collective, or representative action. You may opt out of this arbitration agreement by emailing support@gymbossnotes.com within 30 days of first agreeing to these Terms.
We may update these Terms from time to time. Continuing to use Gym Boss after a change means you accept the updated Terms.

Gym Boss uses artificial intelligence (currently OpenAI models) to generate workout analysis, next-session recommendations, nutrition coaching, and macro/calorie estimates from the notes you enter or, for Premium photo estimates, from a meal photo you choose to submit. This content is generated automatically and is not reviewed by a human before you see it.
Photo estimates are a best guess from a single image. A model cannot see what is underneath the food, weigh a portion, or know how something was cooked, so calories and macros from a photo should be treated as a rough starting point that you review and correct — not a measurement. Always check the estimate before saving it.
AI-generated estimates and suggestions are provided for general informational and educational purposes only. They may be inaccurate or incomplete, and do not constitute medical, dietary, or professional fitness advice. Do not disregard or delay seeking professional medical advice because of anything generated by Gym Boss. If you notice pain, dizziness, chest pain, or any concerning symptom, stop the activity and seek appropriate medical help.
When you use "Ask Gym Boss" or request a nutrition estimate, the relevant text you've entered is sent to OpenAI to generate a response. When you request a meal photo estimate, the photo you selected is sent to OpenAI as well. We do not send your email address, precise identity, or payment information as part of that request. We do not store the photo itself; see Meal Photo Estimates in our Privacy Policy for exactly what is and isn't kept.
