TagPivot
Tag and weight websites while browsing to build a personal knowledge graph of your web history. Data stays local by default.
What it does
Add one or more tags to the current site/page while you browse. Tags are yours; there is no shared taxonomy.
Optionally add a weight (importance / relevance) so your own history becomes sortable beyond recency.
Over time, TagPivot builds relationships between tags and domains. The goal is recall and organization, not recommendation.
Note: TagPivot is intentionally simple. It avoids background syncing and remote analytics so the data model remains understandable.

Privacy
This section is the TagPivot extension privacy policy.
Effective date: 2026-03-05
Data collection
TagPivot does not collect, transmit, sell, or share personal data.
The extension can analyze page content locally in your browser to compute tag relationships (for example: bridges and counterpoints). No page content, browsing data, or user identity is sent to external servers.
Local storage
TagPivot stores derived metrics locally using Chrome extension storage (chrome.storage.local). This may include tag labels, weights, aggregate counts, and structural scores needed for functionality.
All stored data remains on your device. You can remove it at any time by uninstalling the extension or clearing extension storage.
Permissions
TagPivot requires access to the current page to apply tags and compute local relationships. This access is used solely for on-device computation and is never transmitted externally.
Third parties
TagPivot does not use analytics services, advertising services, tracking scripts, remote code, or external APIs.
Changes
If permissions or storage behavior change, the release notes will describe what changed and why.

Pricing
TagPivot is currently distributed as a simple extension. Pricing is a placeholder until a paid feature set exists.
Local tagging + weights + basic exploration.
Optional: rules-based tagging, richer export formats, longer history windows.
Optional: shared tag presets and controlled syncing (only if you choose to add it).
