Privacy & performance.
Reading shouldn’t require an account or a tracking banner. Optional measurements are off by default; you can inspect them locally before deciding whether to share.
This tab’s measurements
These are your device’s samples, not site-wide visitor statistics. Loading, interaction delay, and layout stability are measured across a full page visit; client-side route changes do not reset these vitals. Reload a page for a fresh sample. Some results arrive after interaction or when you switch tabs.
No measurements recorded in this tab. Diagnostics stay off unless you choose an option above.
What stays in your browser
Saving a post or note stores its title, local link, reading position, and revision date on this device. It isn’t synced or included in performance reports. Search runs on public summaries in your browser; its query remains in the address bar so you can reuse the link.
Manage saved reading ↗What optional sharing includes
Performance values, broad page categories, screen-size groups, motion preference, room rendering mode, and a small set of room-chapter and contact/repository-link events. Each measurement has a short-lived sample key for deduplication, not a persistent visitor ID. No pointer recording, session replay, fingerprint, article text, search query, or full URL is sent.
A collection server necessarily receives network metadata such as an IP address. Its operator must configure retention, access controls, and aggregation before enabling sharing. Turning sharing off stops future reports; clearing local data cannot remove a report already delivered.
Ordinary hosting and external links
The host and any external image providers still receive normal requests needed to serve pages and images. External sites you choose to visit have their own privacy policies. Optional diagnostics do not change those ordinary requests.
