One rule, published up front
A challenge has one metric, one time period, one timezone, and one scoring rule. Everyone sees it before they join.
One challenge. Any watch.
Sibaq lets friends on different wearables compete in one private challenge under one published rule. Steps, runs, rides, or sleep. The server scores everyone the same way, so the watch you own never decides the leaderboard.
Read only
Sibaq reads the numbers your platform already has. It never writes to your health data and never asks for write permission.
One source per person
You pick the source that counts for you in each challenge. Two copies of the same ride are never added together.
Honest gaps
A day with no data stays a gap. It is never shown as zero, and the leaderboard says when a number is stale.
Where it stands
Sibaq is in a closed beta with a small group of testers. It is not in any app store yet. There is nothing to download from this page.

What Sibaq does with your data
The short version: it keeps integer daily totals for the metrics you chose to share, shows them to the people in your challenge, and nothing else. No GPS routes, no heart-rate streams, no advertising, no selling. The full text is in the privacy policy, and you can delete your account from inside the app at any time.
