Effective date: 7 October 2026
This policy explains how the Rayofi mobile app handles information when you use it with compatible Rayofi Go-Tone equipment.
Information stored on your device
The app stores workout history (including the sets, weights and reps you complete), custom workouts, equipment choices, custom resistance curves, app settings, and selected device identifiers locally on your device. No Rayofi account is required. Training data is not uploaded to a Rayofi server, except the short training summary you choose to send to the optional AI Coach described below. Android or Apple device backups may include this local data depending on your device and backup settings.
Bluetooth and connected equipment
With your permission, the app uses Bluetooth to find and connect to compatible Go-Tone equipment, send training settings and firmware updates, and receive device status and workout measurements. These exchanges happen locally between your phone and your equipment.
On older Android versions, the operating system may require location permission to discover nearby Bluetooth devices. Rayofi does not use that permission to collect or store your location.
Optional voice features
When you activate a voice feature and grant microphone permission, the app uses the microphone and your device's speech-recognition service to interpret your words. Rayofi does not save audio recordings or send them to a Rayofi server. The speech service configured on your device may process audio under its own privacy terms. Manual controls work without microphone permission.
Optional AI Coach
The AI Coach is optional and only works after you agree to it in the app. When you use it, the app sends your messages and a short training summary to the Rayofi coach service so it can write replies and suggest training plans. The training summary contains the number of connected Go-Tone units, whether they are Pro or standard models, the accessories you own, your weight unit (kg or lb), and your recent exercises, weights and reps. It does not include your name, email address or location.
The coach service passes this information to our AI provider Kie.ai, which uses a model from Google (Gemini) or OpenAI to write the reply. These providers may process the information outside the European Union under their own terms. The coach service itself runs on Cloudflare.
Rayofi does not store your conversations. The coach service keeps only a random install ID and a daily message count, for up to two days, to prevent abuse. Our hosting provider may keep standard technical logs, such as the time, approximate region and outcome of a request, which do not contain your messages.
If you mention pain, an injury or another health matter, that is health information. Only share what you are comfortable with. We use it only to answer you, and only with your consent. The coach gives general training suggestions, not medical advice, and it is not a substitute for a doctor or physiotherapist.
You can withdraw your consent at any time with the AI Coach data sharing switch under Help & Privacy in the app. Everything else in the app keeps working without the coach.
Analytics and advertising
The app contains no advertising or third-party analytics SDKs and does not track you across other companies' apps or websites.
Shopping and support
Shopping and contact links open external services whose own privacy practices apply. If you contact support, Rayofi receives the information you choose to provide so the team can respond to your request.
Your choices and deletion
You can revoke Bluetooth and microphone permissions in your device settings, and withdraw AI Coach consent in the app under Help & Privacy. Deleting the app removes its local data from that device. Device backups are managed separately in your device settings.
For access, correction, or deletion requests concerning information you sent to Rayofi support, contact us using the details below.
