FFIT is a free interval timer that runs in your browser. Using it means you agree to these terms. They're short.
A browser-based interval timer. It beeps. It counts. It ends. No backend, no account, no data stored anywhere except your own device. It's one HTML file. You can view source.
A fitness professional. A doctor. A personal trainer. A substitute for any of those. FFIT tells you when to work and when to rest based on the numbers you gave it. The numbers you gave it are your responsibility, not ours.
We're not going to tell you to consult a physician before exercising—you're an adult. But if something hurts, stop. If the timer says go for another round and your body says absolutely not, listen to your body. FFIT has no idea how you're doing. It's a timer.
FFIT is provided as-is. We built it to work and we intend to keep it working, but we make no guarantees that it will always be available, always be bug-free, or always behave exactly as expected on every device and browser in existence. If it breaks mid-workout, we're sorry. That's what the reset button is for.
To the maximum extent permitted by law, FFIT and its creator are not liable for any injury, loss, or damage—direct or indirect—resulting from the use of this tool. You set the intervals. You do the work. Any consequences are yours.
The code, design, and name belong to FFIT. Don't clone it and pass it off as your own product. Do feel free to view source, learn from it, fork it for personal use, or share the link.
We might update these terms. If we do, the date at the top changes. Continuing to use FFIT after a change means you accept the new terms. We won't email you because we don't have your email.
These terms are governed by French law. Any disputes go to the courts of Paris, France.
