Privacy Policy

Last updated: May 18, 2026
The short version Adnota collects nothing. Your annotations live in your browser, on your machine. We don't have servers that see them, accounts that own them, or analytics that track anything.

What this policy covers

This policy describes how Adnota — both the Chrome extension and the marketing site at adnota.app — handles information. It's intentionally short because there isn't much to describe.

What the extension collects

Nothing leaves your device. The Adnota extension does not transmit any data to us, to third parties, or to any server. There is no account system, no login, and no telemetry.

The extension stores the following locally on your machine, in your browser's chrome.storage.local:

This data never leaves your browser. We cannot see it, retrieve it, or back it up. If you uninstall the extension or clear your browser storage, this data is gone.

What the marketing site collects

The site at adnota.app does not run analytics, telemetry, or tracking pixels. There are no cookies set by us. Standard server logs (IP address, request path, timestamp) may be retained by our hosting provider (Cloudflare Pages) for operational purposes; we do not access or analyze them.

Third-party services

Visiting the marketing site causes your browser to load a small number of third-party resources, each subject to that party's own privacy policy:

Permissions the extension requests

The extension requests Chrome permissions only as needed to function — the ability to read and modify pages you visit (so it can annotate and erase), and access to chrome.storage.local (so annotations persist). No permissions are used to transmit data off your device.

Children's privacy

Adnota is not directed at children under 13 and we do not knowingly collect data from anyone — including children — because we don't collect data at all.

Your rights and controls

Because we don't collect or store your data on our servers, there is nothing for us to delete, export, or correct on your behalf. You retain full control:

Changes to this policy

If we change this policy, we'll update the "last updated" date at the top of this page. Material changes will be noted here. Continued use of the extension or site after a change means you accept the updated terms.

Contact

Questions, concerns, or just want to verify any of the above? Email privacy@adnota.app. The extension's source is also inspectable in Chrome DevTools — you're welcome to verify any of these claims directly.
