Privacy Policy
Last updated: 27 June 2026

Skeinos is local-first and privacy-first. The extension organizes your AI chats (folders, search, prompts, instruction profiles) by reading the pages you already have open. Your conversation content stays on your device.

What never leaves your device
Conversation content, titles, and ids, your search index (searchPostings), your ConversationIndex, and any model Comparison records. These are processed and stored only in your browser (IndexedDB / chrome.storage.local) and are never transmitted, on any tier.
We never read or transmit credentials, cookies, or authentication tokens for any site.
Anonymous diagnostics
The only telemetry Skeinos collects is anonymous diagnostics — crash reports and adapter-health signals (when a chat site changes its layout and breaks an integration) so we can fix breakage quickly. We do not collect usage or product analytics of any kind.

Diagnostics are opt-in and off by default. Nothing is sent unless you turn them on — offered as an explicit choice on the final onboarding step and any time in Settings → Privacy & data — and you can turn them back off at any point. What diagnostics contain when enabled:

Crash reports — the error type, a truncated and filtered error message, and stack frames limited to Skeinos's own code. Host-page frames are dropped, and sensitive substrings (URLs, emails, tokens) are masked.
Adapter-health signals — which supported platform broke, the integration config version, and a fixed code for which page anchor was missing. Every field is a fixed category or a version number.
No conversation content, search queries, prompt/folder/profile/tag names, URLs, or free text are ever included.

How "anonymous" works
Diagnostics events carry no per-user identifier. Our processor's ingest requires every event to include a distinct_id, so all events ship a single fixed constant ("anonymous") that is identical for every install and encodes nothing about you. Crash reports group by their stack fingerprint, not by person. We hold no persistent identifier for you and therefore maintain no server-side profile to access or erase.

Where diagnostics go
When diagnostics are enabled, events are sent by the extension's background service worker — the single point of egress — to PostHog Cloud EU (https://eu.i.posthog.com), our processor, hosted in the European Union. This is the only external endpoint Skeinos contacts. We send hand-built JSON over HTTPS; the extension bundles no third-party analytics SDK and loads no remote code. No session recording or page/DOM capture ("autocapture") is used.

Your controls
Diagnostics are off by default; opting out again is instant and also discards any not-yet-sent events from the local buffer.
Uninstalling the extension removes all local data.
