Terms of Use
Last updated June 2026
Welcome to Crucibull. By creating an account or using the app you agree to these Terms. If you don't agree, don't use Crucibull.
Your account
You must be at least 13 years old. Keep your login secure; you're responsible for activity on your account. One person per account.
Fair play — no cheating
Crucibull's rankings, streaks, leagues and challenges depend on honest effort. Don't fake reps, spoof the camera or pose detection, manipulate the AI counter, use bots or scripts, or otherwise game the leaderboards. We may reset stats, remove you from rankings, or suspend accounts that cheat.
AI feedback isn't professional advice
The rep counting and form feedback are automated estimates to help you train — not medical, physical-therapy, or professional coaching advice, and they can be wrong. Always use your own judgement. See the Health tab.
Subscriptions & billing
Crucibull Pro is offered as a 7-day free trial followed by an auto-renewing subscription ($4.99/month or $35.88/year, or local equivalent). Payment is charged at the end of the trial unless you cancel beforehand. It renews automatically until cancelled; manage or cancel anytime through your app-store account or billing portal. Prices may change with notice.
Acceptable use
Don't use Crucibull to break the law, harass others, post content you don't have the rights to, or interfere with the service. We may suspend or terminate accounts that violate these Terms or the Community Guidelines.
Liability
Crucibull is provided “as is,” without warranties. To the fullest extent permitted by law, we are not liable for injury, loss, or damages arising from your use of the app or from exercising. Your use is at your own risk.
This is a plain-language starter policy and not legal advice — replace it with text reviewed by a lawyer or a policy generator before public launch. Questions: support@crucibull.fit.
Health & safety disclaimer
Read before you train
Exercise carries a risk of injury. By using Crucibull you confirm you're physically able to exercise and that you accept this risk.
Consult a physician before beginning any exercise program, especially if you have a medical condition, are pregnant, are injured, or haven't been active for a while. Stop immediately and seek help if you feel pain, dizziness, shortness of breath, or discomfort.
Crucibull's Trials, targets, and AI form feedback are general fitness guidance generated automatically — they are not medical advice and not a substitute for a doctor or qualified trainer. Warm up, use proper form, train within your limits, and rest when you need to.
You are solely responsible for your own safety. Crucibull and its creators are not liable for any injury or harm resulting from exercise performed using the app.

Camera stays on your device
Rep counting runs entirely on your device using on-device pose detection. Your camera video is never uploaded, recorded, or sent to us or any third party. Only the resulting numbers (reps, form score) are saved to your account.
What we store
Your profile (name, username, email, age, height, weight, goals), and your training data (workouts, streaks, PRs, XP, league standing, posts and comments you create). This lets us sync your progress across devices and power leaderboards.
What's public
Your username and ranking stats appear on leaderboards and to friends. Your real name and contact details are kept private and are never published to public leaderboards.
Service providers
We use Google Firebase (authentication & database) to store your data and RevenueCat/Stripe to process subscriptions. They handle data on our behalf under their own privacy terms.
Your control
You can edit your profile anytime, and permanently delete your account and all associated data from Account → Security → Delete account. Requests: support@crucibull.fit.
Starter policy — have it reviewed before launch. Privacy rules vary by region (GDPR/CCPA).
Community Guidelines
The Forge is a respectful place
Crucibull's Forge is for encouragement and friendly competition. To keep it safe, everyone agrees to these rules.
Be respectful
No harassment, bullying, threats, or hate speech. No content that's sexual, violent, illegal, or that targets people based on who they are. No spam, scams, or impersonation. Keep it clean — profanity and slurs are filtered and may be removed.
Report & block
Tap the “⋯” on any post or comment to report it or block the person — blocked accounts disappear from your Forge. Reported content is hidden from you immediately and reviewed. We aim to act on reports within 24 hours and remove violating content and the accounts behind it.
Zero tolerance
There is no tolerance for objectionable content or abusive users. Accounts that break these guidelines may be suspended or permanently removed.
