Summary of Key Points
This summary provides key points from our privacy notice, but you can find out more details about any of these topics by reading the full policy below.
What are your rights? Depending on where you are located geographically, the applicable privacy law may mean you have certain rights regarding your personal information. This includes the right to request access to, correction of, or erasure of your personal data.
Full Privacy Policy
1. What Information Do We Collect?
We collect personal information that you voluntarily provide to us, including:
- Submission profile: name, email, date of birth, gender, city/state, country, bodyweight, height, grip training experience, hang time, attempt date, notes, occupation (optional), partner gym (optional)
- Video proof: URLs you provide (YouTube, Drive, Instagram, TikTok, etc.) and, when you upload a file, a copy stored for review and portal playback (see retention below)
- Portal account data: magic-link sessions, hang history, training logs, card/avatar preferences, public Watch preference, challenge standings, achievement email tracking
- Guardian fields (minors under 18): guardian full legal name, a guardian email that is not the athlete's email, and a digital consent checkbox (required for every online submit when the athlete is under 18, including under 13)
- Technical / analytics: device and browser type, approximate region, page views, and events via Google Analytics (GA4) when enabled; Cloudflare may process request logs for security and performance. We also log anonymous page paths (and, after login, a portal_open keyed only by athlete id). No raw IP is stored.
- Microsoft Clarity: session replay and heatmaps, with form fields masked. In the EU, EEA, UK, and Switzerland, Clarity loads only after you accept the analytics banner. Other regions load it with the page.
All ages are welcome online and at WDHC gym nights. Online submissions for athletes under 18 require a parent or legal guardian name, a separate guardian email, and consent on the form (see Parental Consent). Under-13 hangs keep Watch private. Public Watch and social spotlight cannot be turned on for an athlete under 13. Sanctioned gym nights remain available with a parent or guardian and host staff present. Contact [email protected] to request deletion of a minor’s data.
2. How Do We Process Your Information?
We process your information to:
- Operate the leaderboard, monthly challenges, championships, and Athlete Portal
- Verify hangs, prevent fraud, and maintain competition integrity
- Compute Grip Age™ and related stats from profile + hang data
- Send transactional email (submission received, approval/deny, magic links, challenge notices)
- Improve the site (analytics) and comply with law
3. Processors and Service Providers
We use infrastructure processors under contract or standard terms, including:
- Cloudflare (Pages hosting, CDN, Turnstile bot protection, Workers/API edge)
- Supabase (database for athletes, submissions, sessions, training logs; object storage for hang video files when uploaded)
- Resend (transactional email delivery)
- Google (Workspace email where configured; Analytics GA4 when enabled)
- Microsoft Clarity (session replay and heatmaps; masked forms; EU, EEA, UK, and Switzerland only after consent)
- Third-party video hosts you choose (YouTube, Drive, etc.) remain under their privacy terms for any link you provide
We do not sell personal data to marketers.
4. When and With Whom Do We Share Your Personal Information?
When a submission is approved, your name, location, and performance metrics may appear on the public leaderboard and challenge boards. Your video link is optional on the public leaderboard: private or unlisted links work for verification; we only show a Watch button if you leave public Watch enabled. We may use performance stats and (with public Watch or separate promo consent) linked video for WDHC promotions per the Media Release. We share data with processors above as needed to run the Services, or when required by law.
5. How Long Do We Keep Your Information?
- Leaderboard / competition records: retained for historical integrity of the sport and rankings unless you request erasure and applicable law requires deletion
- Video URLs: retained for verification and integrity notes
- Uploaded hang files: retained while useful for review, portal playback, integrity, and historical board context; we may remove files after a reasonable period or on a verified erasure request (public leaderboard stats may remain in anonymized or name-only form where needed for sport history)
- Portal sessions: short-lived magic-link sessions; expired tokens are discarded
- Transactional email metadata: delivery logs with our email processor as needed to operate the service
- Analytics logs: retained per Google Analytics, Microsoft Clarity, and Cloudflare defaults (typically months, not forever)
- Support email: as long as needed to resolve the request
To request access or erasure, email [email protected] from the address on your athlete profile.
6. How Do We Keep Your Information Safe?
We use HTTPS, access-controlled admin tools, service-role keys kept off the public site, and reasonable technical and organizational measures. No method of transmission or storage is 100% secure.
7. What Are Your Privacy Rights?
In some regions, such as the European Economic Area (EEA), UK, and Canada, you have certain rights under applicable data protection laws. These may include the right (i) to request access and obtain a copy of your personal information, (ii) to request rectification or erasure (the "right to be forgotten"); (iii) to restrict the processing of your personal information; and (iv) if applicable, to data portability. In certain circumstances, you may also have the right to object to the processing of your personal information. If an athlete in the EEA or UK asks us to delete personal data, we delete it unless a legal exception applies. Competition records may remain in anonymized or name-only form where needed for sport history, as described in section 5. Uploaded files and account data are deleted when the request is verified.
U.S. state privacy laws (including California) may also give you the right to know what personal information we collect, request deletion or correction, and opt out of sale or sharing of personal information. WDHC does not sell personal information. To make a request, email [email protected] from the address on your athlete profile. We will not discriminate against you for exercising these rights.
If you are located in the EEA or UK and you believe we are unlawfully processing your personal information, you also have the right to complain to your local data protection supervisory authority.
To exercise rights, email [email protected] with the email on your athlete profile. We may need to verify control of that address.
8. Cookies and Analytics
We use essential cookies/storage for unit preferences, portal sessions, and security (e.g. Turnstile). Google Analytics may set cookies or use similar tech to measure traffic. Microsoft Clarity may record masked session replays and heatmaps. In the EU, EEA, UK, and Switzerland we ask first: Accept allows analytics and Clarity, and this browser remembers that choice. Reject keeps analytics off and does not load Clarity. The United States and other regions load analytics without that banner. You can block analytics cookies via browser settings or extensions; core submit and portal features still work.
9. Do We Make Updates to This Notice?
We may update this privacy notice from time to time. The updated version will be indicated by an updated date at the top of this page.
10. How Can You Contact Us About This Notice?
