The key word is optional. CronZeno is still the same fully offline GPS race tracker you know. The online features are entirely opt-in: nothing leaves your device until you choose to publish it.
What’s new in version 1.2.9
- Publish racetracks — share a course with the community so other athletes can download and race it
- Publish race events — create an official race that athletes can join by submitting their own GPS run
- Live leaderboards — see real-time rankings with total time, average speed, country, and team information
- Browse online — discover public races and racetracks shared by other users, download them with one tap
- Contribute to a race — submit your run to any open race event, even if you didn’t create it
- Three-level role system — Athlete, Team Manager, and Race Master, each earned by peer endorsement
- Team-restricted races — publish a race visible only to your team members
How the online system works
Every action in CronZeno Online is explicit. When you record a run or create a race locally, it stays on your device. You decide which items to publish, and you can unpublish them at any time.
🛡️ Offline-first, always. GPS recording, race management, and performance analysis all work without an internet connection. An account is only needed for online features.
Step 1 — Create a free account
Open CronZeno, go to the Profile tab, and tap Sign In / Register. Registration uses email and password — no third-party logins required. Once registered, fill in your athlete profile (name, country, team code) so your information shows correctly on leaderboards.
Step 2 — Publish a racetrack
Any registered user can publish a racetrack. Open a track in the Tracks tab, tap the blue cloud icon, and confirm. The app uploads the track metadata and GPX file. A cloud badge appears on the card to show it’s public. You can unpublish at any time by tapping the same icon.
Step 3 — Publish a race event (Team Manager or Race Master)
Open a race in the Races tab, tap Edit / Publish, then tap the blue cloud-upload button. You’ll be asked to choose visibility: Public (visible to everyone, requires Race Master role) or Team only (visible only to your team members, requires Team Manager or Race Master role).
Once published, athletes can find the race in Browse Online, download it, record their run locally, and submit it back to the event.
Step 4 — Live leaderboard
Every submitted run updates the leaderboard in real time. Open any published race and tap View Leaderboard to see the full ranking — position, total time, average speed, and athlete information. The top 3 get a gold/silver/bronze podium display.
The three-level role system
Online permissions in CronZeno are managed through a peer-endorsement role system. You start as an Athlete and earn higher roles through recognition from the community — no administrator approval needed.
| Role | How to earn it | Key permissions |
|---|---|---|
| 🏃 Athlete | Default — granted on registration | Publish racetracks, browse & download public content, submit runs to open races, view leaderboards |
| 👥 Team Manager | 2+ athletes confirm your team alias | Everything above + publish team-restricted races (visible only to team members) |
| ⭐ Race Master | 2+ Team Managers endorse you | Everything above + publish public races (visible to the whole community and on the website) |
Roles are cumulative: a Race Master is also a Team Manager and an Athlete — no permissions are ever removed when earning a higher role.
Public vs. Team-restricted races
When a Team Manager or Race Master publishes a race, they choose its visibility:
- Public race — visible to all users in the app and on cronzeno.com. Appears in Browse Online for everyone. Only Race Masters can create public races.
- Team-restricted race — shown with an 🔒 orange lock icon. Visible only to members of the owner’s team. Does not appear on the public website. Available to Team Managers and Race Masters.
🔒 Team-restricted visibility is enforced at the database level — it is not just a UI filter. Even a direct API call cannot return a restricted race to a user who is not a team member.
Privacy
CronZeno has always been privacy-first, and the online system keeps that promise:
- Nothing is uploaded automatically — every publish is a conscious action you take
- GPS route files (GPX) are stored in a private bucket — only authenticated users with the right role can access them
- Your email address is never shown to other users
- You can unpublish any content at any time
