What's inside

Built for the whole season

Every objective, session, and protocol connected in one structured, searchable place.

Athlete & team projects

Spin up dedicated projects for individuals, squads, training camps, and competition phases — each keeping its objectives and protocols linked.

Sweat-loss estimation

Estimate fluid loss from duration, intensity, and environmental conditions, then turn it into concrete fluid-intake targets.

Reusable hydration templates

Build hydration and recovery templates once, then apply them across athletes and phases so protocols stay consistent.

Body-mass & readiness tracking

Monitor body-mass changes through the season and log readiness checklists to keep workload and recovery in balance.

Interactive dashboards

Read clear signal on hydration consistency, workload balance, recovery effectiveness, and long-term athlete development.

Journals, protocols & reminders

Coaching journals, protocol libraries, milestone calendars, recovery windows, advisory tips, search and reminders — all on hand.

About us

Sports science, kept private.

💧We are Wmax — a small team of sports-science nerds, former trainers, and builders who got tired of watching hydration and recovery decisions get made on gut feel and scribbled notes. We set out to give performance professionals a calm, structured place to plan the unglamorous work that keeps athletes healthy: fluid, recovery, and readiness.

🏋️Wmax is built for strength coaches, athletic trainers, and performance staff juggling dozens of athletes across seasons, camps, and competition phases. Spin up dedicated projects for individuals or whole squads, connect every objective, session, and protocol in one place, and stop hunting through five different apps to answer one question about a single athlete.

📊Inside, you can estimate sweat loss from duration, intensity, and heat, build reusable hydration templates, set fluid-intake targets, and track body-mass changes across the season. Dashboards turn it into clear signal, while journals, checklists, calendars, and protocol libraries keep years of planning searchable. And because everything lives on your device, your athletes' data stays yours.

Plan the recovery. Trust the readiness. Win the long season.

Privacy policy

Your data is none of our business.

Effective Date: June 2026

Wmax was built on a simple, slightly old-fashioned idea: your data is none of our business. The app is designed to run entirely on your device, so we never collect, store, transmit, or even see anything you put into it. Here's exactly what that means.

01 Information We Collect

Nothing. Wmax requires no account, and we never ask for your name, email, phone number, or location. Athlete profiles, projects, teams, hydration templates, sweat-loss estimates, fluid-intake targets, body-mass records, journals, checklists, milestones, and protocols are created and held by you. We have no servers receiving them and no way to read them.

02 How We Use Information

Because we never collect your information, there is nothing for us to use, analyze, profile, monetize, or sell. Every calculation, dashboard, and suggestion is generated locally on your device, for your eyes only. There is no behavioral tracking and no advertising profile, here or anywhere else.

03 Data Storage

All of your Wmax content is stored locally in the app's own storage on your device. There is no cloud sync, no remote backup, and no transmission of your records to us or any third party. Your planning data never leaves the device unless you choose to export or share it yourself.

04 Third-Party Services

Wmax embeds no third-party analytics, advertising networks, trackers, or data-harvesting SDKs. We don't hand your activity to social platforms or marketing partners. The app is intentionally self-contained — there is no quiet pipeline sending your work elsewhere.

05 Data Security

Keeping data on-device is itself our strongest safeguard: information that is never uploaded can't be intercepted in transit or exposed in a server breach. Your records inherit the protections of your own device, so we recommend using your operating system's lock screen, encryption, and access controls.

06 Children's Privacy

Wmax does not knowingly collect personal information from anyone, including children under 13, because it does not collect personal information at all. With no data-gathering mechanisms, the app aligns with COPPA principles by design rather than by promise.

07 Your Control

You are always in complete control. Add, edit, or delete any record at any time, and remove everything permanently by deleting the app. Because there are no accounts or cloud backups held by us, uninstalling fully and irreversibly clears the data Wmax stored locally — so export anything you want to keep first.

08 Changes to This Policy

If we update this policy — for example, to reflect new features — we'll revise the Effective Date above and publish the current version with the app. Our core commitment won't change: Wmax stays a local-first, no-collection tool.
