Tabitha is a browser extension that helps you manage, save, and search your tabs and windows, with optional AI features. This policy explains exactly what data Tabitha handles, where it is stored, and the limited cases in which data leaves your device.
Short version: Tabitha stores everything locally on your own device. It has no servers, no account system, and no analytics or tracking. Data only ever leaves your device if you choose to enable the optional AI features by adding your own Google Gemini API key — and even then, it goes directly from your browser to Google, never to us.
Who we are
Tabitha is developed by Frisson Labs. We do not operate any backend service that receives, stores, or processes your data. There is no “Tabitha account.”
Data stored on your device
All of Tabitha's durable data is stored locally in your browser (via IndexedDB and extension storage). It never syncs to us or any third party. This includes:
- Saved windows and tabs — page titles, URLs, and favicons of windows/tabs you choose to save.
- Captured page content — when you save or analyze a page, Tabitha may store the page's text (and, transiently, its HTML) locally so it can summarize and search it.
- AI-generated data — page summaries, text chunks, and embedding vectors used for on-device semantic search. These are created only when AI features are on.
- Session snapshots — a rolling history (up to 20) of your open windows' titles and URLs, so you can restore a previous session.
- Settings — your preferences (theme, backup settings, etc.) and, if you provide one, your Google Gemini API key.
You can delete this data at any time by removing saved windows, clearing the extension's data, or uninstalling the extension.
Your Google Gemini API key
The AI features are optional and require your own Google Gemini API key:
- It is stored only on your device, in the extension's local storage.
- It is never transmitted to us.
- It is excluded from any backup files Tabitha creates, so it won't leak if you share a backup.
- It is used solely to authenticate your requests directly to Google's Gemini API.
When data leaves your device
Tabitha's core tab-management features work fully offline. Data leaves your device only in these specific cases:
1. Google Gemini API (only if you enable AI features)
If you add a Gemini API key, the following is sent
directly from your browser to Google's Gemini API
(generativelanguage.googleapis.com) to power the
corresponding feature:
- Summaries: the URL, title, and extracted text of a page you save/analyze.
- Semantic search & indexing: page summaries and text chunks (to generate embeddings), and your search queries.
- Chat: your questions plus the relevant snippets retrieved from your own saved content.
- Auto-organize: the summaries of the pages being grouped.
This data is processed by Google under Google's Privacy Policy and the Gemini API terms. Tabitha never receives a copy. If you never add a key, none of this data is ever sent.
2. YouTube transcripts
When you analyze a YouTube video page, Tabitha requests that video's transcript from YouTube's own endpoint (in the context of the YouTube page you already have open). This happens only for YouTube pages and only during analysis.
3. Favicons for chat citations
When the AI chat shows a cited source, Tabitha loads that site's favicon
from Google's public favicon service (google.com/s2/favicons).
Only the site's domain is included in that image request. (The main tab
list uses the browser's own favicons and makes no such request.)
What we do NOT do
- We do not collect analytics or telemetry of any kind.
- We do not use trackers, advertising, or fingerprinting.
- We do not run any server that receives your data.
- We do not sell, rent, or share your data with anyone.
- We do not transmit your browsing history anywhere (your saved data stays on your device; only content you explicitly save/analyze is used, and only as described above).
Permissions
Tabitha requests only the permissions needed for the features above. A plain-language explanation of each permission is provided in the store listing.
Children's privacy
Tabitha is a productivity tool not directed at children and does not knowingly collect any personal information from anyone.
Changes to this policy
If this policy changes materially, we will update the “Last updated” date above and the version published with the extension.
