Effective date: August 11, 2026
Thinklet is a note-taking browser extension. This policy explains what data Thinklet handles and how.
Thinklet does not collect, transmit, sell, or share any of your data. Everything you type stays on your own device, in your own browser, unless and until you turn on optional cloud sync (see “Future: optional cloud sync” below).
Thinklet stores your notes (title, content, and created/edited timestamps) using chrome.storage.local, a storage area built into Chrome that is local to your browser profile on your device.
Thinklet does not have a server. It does not send your notes, or any other data, over the network.
Thinklet does not use analytics, telemetry, crash reporting, or advertising SDKs of any kind.
Thinklet does not read the content of any web page you visit, your browsing history, your bookmarks, or any other browser data outside of the notes you create inside Thinklet itself.
Uninstalling Thinklet removes its locally stored notes along with it, the same as uninstalling any other extension. Exporting a note (Markdown or PDF) saves a file to a location you choose, using Chrome’s normal download and print flows; Thinklet does not otherwise copy your notes anywhere.
Chrome requires every extension to declare the permissions it needs. Thinklet requests:
| Permission | Why Thinklet needs it |
| storage | To save your notes locally in chrome.storage.local so they persist between browser sessions and stay in sync across the toolbar popup, the side panel, and the full-tab editor. This is the only way Thinklet stores anything. |
| sidePanel | To let Chrome dock Thinklet in its built-in side panel, so you can keep a note open next to other tabs instead of only in a popup that closes when you click away. |
Thinklet does not request host_permissions, meaning it cannot read or modify the content of any website. It does not request tabs, history, bookmarks, cookies, or any permission that would let it see your browsing activity.
We plan to add an optional feature that lets you sign in and sync notes to your own cloud account (via Supabase), so your notes can follow you across devices, with chrome.storage.local kept as an offline cache. That feature:
Will be off by default. Nothing will be sent off your device unless you explicitly sign in and turn it on.
Will only transmit your own note content, associated with your own account, secured so only you can read it.
Will require adding new permissions to the extension (network access to the sync service), which Chrome will ask you to approve on update, and which will be reflected in an updated version of this policy before that feature ships.
Until that feature ships, the “Summary” section above is accurate: nothing leaves your device.
Thinklet is not directed at children and does not knowingly collect data from anyone, regardless of age, because it does not collect data from anyone at all.
If this policy changes (for example, when cloud sync ships), we will update this document and update the effective date above. Continued use of Thinklet after a change means you accept the updated policy.
