Privacy at a glance
QTimer helps you create, share and run workout timers. No account is required, and workouts can be created and used directly in your browser.
When you use AI workout generation, the description you submit is sent to the QTimer API and processed by its configured AI service.
Workout links
QTimer workout links contain the workout configuration in the URL. That can include a title, exercise labels, durations and repetitions. Anyone who receives a link may be able to read, use and share that information.
Do not put confidential, medical or personally identifying information in workout titles, labels or shared links.
AI workout generation
The workout description you submit is sent to qtimer-api. The API applies validation and safety checks, then sends the relevant prompt to Cloudflare Workers AI, which is the configured provider in this project.
If a generated result needs correction, the provider may also receive the generated candidate and structured validation feedback so it can try again. QTimer does not deliberately persist prompts or generated workouts in an application database. Infrastructure and provider systems may retain operational data or logs outside QTimer’s direct control, and their exact retention is not verified here.
Please do not submit sensitive personal or medical information.
Analytics
QTimer uses Google Analytics to understand coarse product usage and improve the application. QTimer intentionally excludes AI prompts, workout titles, step labels, serialized workouts, URL query parameters and URL hashes from analytics events and page views.
Google may process technical data under its own policies. QTimer does not provide a consent or opt-in flow. You can restrict analytics with browser settings or blocking tools if you choose.
Local browser data
QTimer does not use an account database or browser storage for workout content. Sound, voice narration and screen-awake choices are session controls on the ready screen; they are not saved by QTimer. The workout itself stays in the URL you open or create.
Service providers
- GitHub Pages hosts the website. See GitHub’s privacy statement.
- Cloudflare Workers runs the API, and Workers AI processes AI generation. See Cloudflare’s privacy policy.
- Google Analytics measures product usage. See Google’s privacy policy.
These providers operate infrastructure that QTimer does not control, including their operational logging and retention.
Retention
QTimer has no application database configured for prompts or workouts, and the application does not deliberately persist them. The QTimer API may process a prompt and generated result in memory while fulfilling a request. Operational logs, rate-limiting systems and provider-side retention are outside the repository’s verified application behavior.
User choices
- Avoid entering sensitive content in prompts, titles and labels.
- Remove QTimer preferences by clearing site data in your browser, although this version does not save those controls.
- Keep workout URLs private when their contents should not be public.
- Use browser privacy settings or blocking tools to restrict analytics.
Fitness disclaimer
QTimer organizes timers and workouts. AI-generated workouts are general information, not medical advice. Choose activity appropriate to your health and ability; stop and seek appropriate help if you experience alarming symptoms.
