How it works
A transparent, rule-based explanation of the signs you report — nothing more, nothing hidden.
1. You choose a platform
Each platform has its own list of observations, written for how that app really behaves.
2. You select what you've noticed
We only use your answers. We never connect to, scan or look up any account, and your selections stay in your browser tab.
3. We apply documented rules
Each observation is tagged as a weak sign (often caused by privacy settings), a consistent sign (commonly seen with blocking but with other causes), or an explicit platform notice.
- Insufficient information — nothing selected.
- Inconclusive — signs with many plausible explanations.
- Possible signs of blocking — two or more consistent signs, with alternatives still possible.
- Platform explicitly indicates a block — you reported a notice shown by the platform itself. Still user-reported, not verified by us.
Why no percentages?
A probability would need a validated, representative dataset. We don't have one, so showing a number would be misleading.
