Coach the architecture.
Not just the rep.
Chillsy Rillsy breaks every technique into primary skills, supporting elements, and progressive stages — so improvement stops being a guess and becomes a system you can see, plan, and repeat.
Six ways to build a training system, not a to‑do list.
Every feature exists to turn a single technique — or an entire season — into something structured, traceable, and easy to refine.
Skill Trees
Decompose any technique into primary skills and supporting elements, laid out visually from foundation to mastery.
Prerequisite Pathways
Define what has to be learned first. Sequence progression so nothing gets trained out of order.
Drill Mapping
Connect specific drills directly to the technique components they're designed to train.
Mistake & Correction Library
Document common execution errors alongside the corrective strategies that fix them, permanently at hand.
Readiness & Reflection
Log progress journals, readiness evaluations, and session reflections that build a real record over time.
Project Workspaces
Organize athletes, seasons, objectives, checklists, and technique libraries in one dedicated space.
Build a skill path, node by node.
This is the same logic that powers every skill tree inside the app. Click a node to complete it once its prerequisites are unlocked, and watch readiness climb.
Front Foot Strike — Skill Path
A simplified example tree. Foundation unlocks components, components unlock drills, drills unlock mastery.
Built by people who got tired of flat checklists.
We started Chillsy Rillsy because coaching great technique has always been harder than it should be. Athletic skill isn't one thing — it's dozens of smaller components stacked on top of each other, and most training tools flatten that complexity into a checklist instead of a system. We wanted a workspace built the way skills actually get learned: piece by piece, in order, on purpose.
Our mission is simple — turn technical coaching into an architecture, not a guess. Every movement an athlete performs can be broken into primary skills, supporting elements, and progressive stages, and once you can see that structure clearly, refining it stops being guesswork and starts being engineering.
Inside Chillsy Rillsy, coaches and athletes build real skill trees: prerequisite pathways, drills mapped to technique components, a living library of mistakes paired with corrections, and clear completion criteria for every milestone. Dedicated project workspaces keep athletes, seasons, and sessions organized in one place.
🎯 Mastery isn't luck — it's a system you can see.
Nothing leaves your device. Ever.
The short version: Chillsy Rillsy doesn't collect, store, or transmit any of your data. The long version is below.
Information We Collect
We collect nothing. There are no accounts, no sign-ups, no names, no email addresses, and no location requests. Your skill trees, drills, notes, journals, and workspaces are created and stored entirely on your own device.
How We Use Information
Because nothing is collected, nothing is analyzed, profiled, or sold. There is no advertising engine and no usage analytics. Every feature runs on-device, with no data ever leaving your phone or tablet.
Data Storage
All content lives in local, on-device storage only. There is no cloud sync, no remote database, and no transmission to any server we or anyone else operates.
Third-Party Services
No third-party analytics, advertising networks, tracking pixels, or external SDKs are integrated into the app. Nothing is shared, because nothing is collected in the first place.
Data Security
Since your training data never leaves your device, there's no server-side database to breach and no credentials to protect. Standard device-level protections (passcode, biometrics, up-to-date OS) keep it safe.
Children's Privacy
Chillsy Rillsy does not knowingly or unknowingly collect personal information from anyone, including children under 13. Because no data collection occurs at all, the app is COPPA-friendly by design.
Your Control
You have full control over everything you create. There are no accounts to manage and no cloud backups. Deleting the app removes all local content permanently — nothing remains anywhere else.
Changes to This Policy
This policy may be updated to reflect new features or for legal clarity. The Effective Date above will be revised whenever changes are made. Continued use after an update means you accept the revision.
